Bitcoin Mining with a Raspberry Pi - Lonewolf Online

“Bitcoin” mining on Raspberry Pi 3 with multiple USB miners

I’m just trying out “Bitcoin” mining to familiarize myself with the world of mining before investing in more powerful Th/s miners. I plan to use one of my Raspberry Pi’s with a powered USB hub connected with possibly 2-4 USB miners running with a USB fan as these things get pretty hot. Possible miners would be multiples of the Antminer U1, Antminer U2, or the GekkoScience device. My questions are: 1-Will a Raspberry Pi 3 work with a USB hub? 2-Can CGminer run properly with multiple devices and be able to consolidate the processing power of each miner?
Thanks in advance.

[WTS] 2x BFL Bitcoin Miner [7GHs and 10Ghs], power supplies, various USB Miners and Raspberry Pi Model B for controlling BFL

Can not sell for at least 6 months
I need to get these things out of my house. Everything runs perfectly and have been run for about 6 weeks [turned them off back in the summer after running too hot]. I bought them from Butterfly Labs directly at retail price. I am interested in knowing how much I can get for them. Doing some math I think I can get about $300-$350
I will not be making the sale until July, when I can actually get to them and get them shipped out. [No pictures, again just looking for reference prices]
What I have:
1x BFL Bitcoin Miner 7GHs (Likely could part for $60)
1x BFL Bitcoin Miner 10GHs (Likely could part for $90)
5x USB Block Eruptors 330MHs (Likely could part with the lot for $35)
2x AntMiner 2GHs [Never used] (Retail on Amazon for $35 each, could sell for $30 each)
1x Raspberry Pi Model B [would probably sell 4GB SD Card, USB Hub, Power Supply, and 16x2 LCD display with it] (Would sell the entire package for $70)
Willing to ship US only

Which Bitcoin Miner should I get?

Hello, I’m wondering which Bitcoin miner I should get. I’ve seen some RaspBerry Pi’s with Miner USB’s on them but that’s about all I know.
Can anyone recommend a good miner for my needs?

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit:‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.
Zybo Z7-10 Xilinx Zynq 7010 17,600 $199 Yes Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.


icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)


Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)


What can I do with an FPGA? / How many LUTs do I need?

part 3: down the NodeRed rabbit hole - resurrection (long)

so, now that i've got about 4 weeks of NR experience under my belt, i thought i would do a follow up and show a few new flows. plus, i've picked up a few new hardware add-ons. namely a Harmony Hub and a coupla Sonoff/Tasmota S31.
one of the new things i did was setup some global.variables i can use in any flow.
1] is pretty obvious, does my bayesian sensors think i'm home/not_home, and then save it to a global.variable.
2] reads the MQTT for my S31 power monitor on my dumb TV. if it's > 100, then the TV is ON, <= 99, then TV is OFF (or in the process of turning off). then set a global.variable for on/off.
3] i changed the day/night temperatures to global.variables.
4] this one gets the current volume level of my Sonos and then stores that to a global.variable. (get to why further below)
5] this one i talked about in another post here:
okay, so now that i know if my dumb TV is on/off, then i can add it into my "away" (and "bedtime") flow. that gray one on the bottom right is using the HarmonyHub control node to fire the power toggle. (which i'll get to further below) plus it'll stop my Sonos, if it's playing.
also you may notice the "alexa TTS" one, that's a subflow, which is a bit of reusable flow, you can put anywhere you want it. this one picks a random number between 1 and 10, then alexa TTS plays the corresponding message.
this was also my attempt to get alexa to say "aaaf-firmative" like newt in aliens.
doesn't really work, but i'm determined to make this happen. gonna have to figure out the proper phonetics of it. then i'm totally gonna get her to do a stutter like max headroom on one of the other responses. but, my ultimate goal is to get her to do "twiki" from buck rogers. beaty beaty
anyways, i've also added that subflow to all my switch on/offs. along with an MQTT log.
now for some of the new stuff...
here's a sleep timer. if i'm listening to music in bed, i can activate this with "alexa turn on sleep" and what it does, is it takes the current volume level of my Sonos, stored in a global.var, stores it in a flow.var, then subtracts 1 every minute, until it reaches zero. if the volume is at 30, then it'll be 30 mins until zero.
once it reaches zero, it stops the music, sets the volume back to the original state (ie: 30) and then turns itself off.
there's an issue when you use something like a Harmony Hub to turn on/off dumb devices via input_bool, or switches, or lights, etc.: that once you turn it on via NR, HA, HHub, Alexa, etc., then HA thinks it's on. if you then turn it off via the device remote, HA won't let you turn it on again, because HA thinks its already on.
so, i had to use a script and a "dummy" input_boolean. by dummy i mean, that i do not care, and will not EVER care, what it's state is. on. off. whatever. won't need it. it just needs to be there for the script to work.
input_boolean: mac_x: game_x: candles_x: tv_x: 
hide them from emu_hue, cause Alexa doesn't need to see them either.
emulated_hue: host_ip: 10.xx.xx.xx exposed_domains: - input_boolean - script entities: input_boolean.tv_x: hidden: true input_boolean.mac_x: hidden: true input_boolean.candles_x: hidden: true input_boolean.game_x: hidden: true 
add some scripts.
script: tv: alias: "TV" sequence: service: input_boolean.toggle entity_id: input_boolean.tv_x game: alias: "Game" sequence: service: input_boolean.toggle entity_id: input_boolean.game_x mac: alias: "Mac" sequence: service: input_boolean.toggle entity_id: input_boolean.mac_x candles: alias: "Candles" sequence: service: input_boolean.toggle entity_id: input_boolean.candles_x 
so instead of key'ing off the input_booleans, i key off the script call. "alexa, turn on candles" calls the script, which toggles the i_b but i only care about the state change of the script. then NR does it's thing.
notice tho, that it's a little smart. if the tv is already on, via that global.var, then it just switches inputs, otherwise it turns it on, waits 7 seconds, then switches inputs.
okay, here's something REALLY advanced.
i have a second pi running cgminer with a USB hub and some USB stick ASIC bitcoin miners. and every once and a while, they stop working and need to be reset. and you can't just restart, you gotta kill the power to the hubs to get them to reset. and then restart cgminer.
enter NR cgminer node and the cgminer API.
so every 5 mins, hit the cgminer API, it returns stats in json, dump those to mqtt. use the function node to pull out the array nested values we need to look at. look for a zero value in any of them. if the input_boolean "auto-reset-miner" is on, then lets reset.
stop cgminer, wait, turn off the USB hub, wait, turn on hub, wait, start cgminer, send an alert to mqtt and SMS me.
now the real magic is the red exec "start cgminer" node. because we stopped cgminer, we have to start it again, on a whole other computer than NR is on.
it basically does a SSH into the miner pi and starts up cgminer. this was difficult to accomplish inside a docker of NR. i had to move some ssh keys around and then reference them with full paths. then i had to do an ssh-copy-id so it didn't require a password.
ssh -i /data/.ssh/id_rsa [email protected] "start cgminer commands" 
anyways, i'm really proud of this one. it was difficult to figure out how to make it work. lots of different moving parts coming together.
here's something i'm still working on. a remote control using the NR dashboard UI.
something i can just put an icon on my iphone home screen and use from the couch.
anyways, enjoy.
or don't. i'm not your cruise director.
you do you.

Jihan Wu: "blocksize is a minor issue that cost the community so much damage. It has given too much opportunities for some people who are altcoin developers. We have more challenge to solve, for the future of Bitcoin rather than a blocksize thing."

Jihan_Bitmain full quote : "Hi I am fine. Thank you. I am pretty busy after the U.S. trip, and I don't have the time and mood to talk on the social media right now. But I read on btc and bitcoin. BIP109 is a compromise. They want to reach something by compromising, but it will not work. 2MB cap would bring us trouble in less than 1 year if it is selected by miners. I don't think I will vote for BIP109. We need a plan that will not drag the community into the blocksize issue from now on. For the growth of Bitcoin, blocksize is a minor issue that cost the community so much damage. It has given too much opportunities for some people who are altcoin developers but also claiming to be Bitcoin reference client software developers. We have more challenge to solve, for the future of Bitcoin rather than a blocksize thing. Bitcoin has a very long way to go to be a world reserve currency. I think everyone reading this post should buy a mini PC, like Intel NUC, in his home, with 500G-1TB disk and wifi. It cost less than 500$. It is running a full node, so don't go extreme to try to run it on a 10$ worth second handed RasPi. It will be able to support the network for at least 2-3 years. By adding HDD on the USB port and some pruning, it will be lasting even longer. You can express your point of view by running a certain kind of full node you like. It will be much more cheap and stable than running in VPS in the long term."

Check out Part 2 of our first Skycoin Official AMA with Synth

Enjoy Part 2 of 2 of the Skycoin Official AMA with Synth for March, 2018. Part 1 is posted here.
How will skywire stop centralization such as massive skywire node forwarding servers, like with the current internet?
There will be more competition between pools in Skycoin than there is in Bitcoin. If that problem occurs, then we will deal with it, we have strategies and models in place to handle this potential scenario.
How will it stop whales building humongous skyminer pools in massive cities such as New York that will forward all the nodes in that city?
If a whale wants to come in and invest 1 billion dollars, to take control of the internet service for a whole city, then it will only make Skycoin grow faster. If it becomes a problem like what is happening for Bitcoin right now, then we have plans in place to handle the issue.
The miner pools can only be so abusive in Skycoin, because if the pools are too abusive, then other people will switch to smaller pools that give them a better deal.
How do you solve mining for bandwidth? What is to stop an attacker putting two routers next to each other to print money?
This is of the reasons why Skycoin will work and we do not think we have any viable competitors. We know how to solve this problem.
The short answer is that we are not paying users for bandwidth. Users are paying each other. So if you put two routers next to each other in a loop, then you are paying yourself for your own bandwidth! So you are not printing money. It is the same as moving money from one of your wallets, to the other wallet.
Skycoin does not “print money”. There is zero inflation. It is a closed loop economy.
Our mathematical models show that if the network is not running in closed loop, that you can always game the system and eventually botnets will take over all of the rewards.
There is another way we found, which uses a bandwidth credit system and later we can build futures and derivatives markets. Since bandwidth is scarce, but is wasted if not used our algorithm allows a certain amount of fraud (acceptable loss ratio) to be factored in but mathematically guarantees that the fraud stays below a certain threshold. There is a maximum amount or upper bound a node can get away with, before it detected and the other nodes stop working with the node.
Basicly, eventually the nodes have a reputation system and nodes prefer other nodes who follow the rules over nodes that try to engage in bandwidth fraud.
We have a simple working solution for the testnet, then we will start building up the full solution, which will also improve the network performance a lot by directing most of the rewards at trustworthy nodes with a high uptime, lower latency and higher bandwidth capacity. The node reputation system will take a bit of work, but will allow us to do a lot of new thing with QoS and routing.
Since the people using Skywire resources depend on those resources to report what happens to the outside world, how do you stop adversarial actors from defrauding users using information asymmetry between the users and the blockchain? How do you do this without an enormous amount of overhead?
Adversarial actors are a major problem in any system where anything of value is concerned.
If you do not have a solution for fraud, then bots will come in and steal all the money. Imagine you are running a poker site with 100,000 humans on it. Then someone floods the poker site with 1 million bots (who are better at poker than humans). The bots are going to steal all the money from your users and they will leave (because they are only losing now and the game is not balanced anymore).
If you tell people “I will give you money for running this computer program”, there are people who control 15 million computers and they will just run the program on their botnet. All of the money will goto the bots.
Skywire solves the bot problem by a sort of peer-to-peer whitelisting protocol. We do not let people flood the network with bots. Each node maintains a peer list and if you want to peer a human has to add the peer on both ends by hand, so it’s harder for a botnet to come in and try to take over.
People, because they are social, will peer with people they know personally (their own social network or communities). It’s designed so that people with high quality, hand curated peer lists will have a significant advantage over someone who peers with 10 million slow botnet computers, running on laptops running windows XP. Also people who own dedicated hardware will also have much better performance metrics and will be rewarded more than botnet computers.
The overhead for the record keeping is only 2% to 6% of the total bandwidth in the network, depending on how long the sessions are and the specifics. So the overhead is at the same level as for the existing internet.
Why did you use Orange Pi’s, that have their NIC on a USB 2.0 bus, for the hardware in the Skynodes?
Ideally, for security, the NIC should not have DMA (Direct Memory Access). USB 3.0 is a nightmare. USB 2.0 is bad and USB 1.0 is actually better (more secure, but slower).
The NIC drivers or firmware usually have a lot of dangerous security problems.
We are designing a custom PCB and there are several security, cost, design issues that do not have a clear best solution. The NIC is on the USB 2.0 bus, primarily because that is what the chip supports and because of cost.
What is to stop the cable lobbyist and the FCC who have already proven they will go against the will of the people from banning skywire? Couldn't they stop people from getting access to the backhaul and outright outlaw the entire concept? When I asked on the Telegram everyone dismissed the concern and said 'its impossible to stop us, look at the darknet'. And while that is true, for skywire to work don't you need widespread normie adoption? What percentage of people would actually run this if they banned it?
There are many, extremely wealthy and powerful groups that are being squeezed out by the FCC and the internet monopolies. There are some surprising large and powerful players that will support (publicly or clandestinely) any project that gives them some breathing room from the telecom squeeze out.
We want them to try to ban Skywire. That means we are winning.
You have to understand the context of the FCC and the cable companies.
The cable companies were forced to be very aggressive and remove net neutrality and start using mafia extraction tactics against companies like Netflix and Google, because of earnings pressure. The cable companies all have declining revenue because people are using the internet for video and are “cord cutting”. The CEOs and management are desperate to keep their stock prices up and slow down the earnings decline.
The CEOs of the cable companies are under extreme pressure to increase earnings in the short term, but are using tactics that will create a lasting long term backlash. The CEOs will increase earnings, they will see their stock prices go up, they will cash out their options and retire to the Hamptons. The backlash will be the next CEOs problem.
Skywire is global and the FCC only matters in the US. In Europe there is much more diversity in ISPs and you wont see the type of battle and resistance they will put on in the US.
The cable companies are dying. They are the dinosaurs whining and moaning before the meteor impact. Fighting technology innovations like Skywire is part of the process of the demise of these telecom monopolies, but it is not something to worry about.
If they are attacking us, it means we are winning. We will be ready.
Do you have an estimate for when coin hours will have value and be tradable?
We are working on getting the exchange up, but it will need to wait until the testnet. First we will make coinhours tradable, then we will open them up for exchange.
How, in simple terms, do coin hours prevent spam?
The more they spam, the more scarce and expensive the coinhours become. If someone spams or attacks Skycoin, the Skycoin price will actually go up.
Since there are only a finite, scarce number of Skycoin and each Skycoin generates a fixed number of coinhours per hour; then coinhours become scarce and valuable. They put a price on transactions.
An attacker or spammer has to ask “Should I just sell my coinhours for money or should I spam and lose money?”. Eventually the spammer will use up all of his coinhours and then will have to buy them from someone else to keep spamming. Eventually they will even drive the market rate of the coinhours up, until the spamming becomes so expensive that they run out of money or give up.
On telegram you wrote coin hours are meant to be volatile if I'm not mistaken. Will this be a problem in the future?
It depends. By shuffling volatility from Skycoin, to the coin hours it makes Skycoin more valuable as a store of value and as a currency for transactions.
We want people to spend coin hours. If Skycoin is going up everyday 5% a day, why would you spend it? If we priced the bandwidth in Skycoin, the whole network would shutdown because everyone would just be hoarding their Skycoin instead of spending them! That is why we introduced coinhours.
Coinhours solve the problem of hoarding and gives people a currency which they are encouraged to spend. Skycoin is a better store of value because there is no inflation, while coinhours are better for transactions because they have an inflation rate that encourages people to spend them.
The market cap of the Skycoin coinhours could actually be higher than the market cap of Skycoin under some conditions.
Everyone is very excited to see what the price coinhours settle at. People are betting on the market and cannot wait to trade and speculate on the coinhours (either dumping them before they go down to zero, or hoarding them incase they go up 500x). I was surprised at how excited people are about the coinhours.
Are there any more coins launching on skyledger soon you can talk about?,, SPACO,, and more...
I have been so busy with Skycoin I cannot even keep up with the new ICOs.
We are opening up the platform now and more people will be launching coins that I could possible keep track of. We should probably have a registry to track the Skyledger ICOs.
Will it be easier to launch coins on skyledger in the future? Any other skyledger updates?
Yes. We have a script now for launching new coins!
In 30 seconds you will be able to: Create your coin Have your ICO software running to collect money Have the coin automatically listed on an internal exchange (instead of waiting 8 months to get listed on some mega exchange) Have mobile, desktop and hardware wallet support Skyledger is getting a rebranding and its own marketing team. We have several flagship coins in development, that will help alot for Skycoin marketing.
Synth mentioned months ago in the telegram chat that Obelisk was still in development, when and how will the algorithm be tested and release? How are the actual transactions validated if obelisk is not the algorithm used?
We have done several simulations. There are several peer reviewed academic research papers published about it. There are open source simulations in the github repo.
The exchanges are worried about us enabling the full consensus algorithm without enough testing. We have to do a lot of testing before we turn everything on.
Currently the exchanges forced us to use a masternode dev check-point system. Over time, we are going to make extensive changes to the node and keep minting on the checkpoint system, while rolling out everything. Then after extensive testing, will roll out everything in stages.
The testing of the new features and stages, needs to be done on a smaller coin (other Skyledger coins) before being rolled out to Skycoin. Skycoin’s market cap is too large and we have to be cautious about bugs and not rolling out new code before its tested.
The dev check-point system is a compromise that allows us to test new consensus algorithms, while protecting the exchanges. If the exchanges lose money from a bug and lose $200,000 in Skycoin then we have to pay them for the lose basicly.
The exchanges are all short-staffed because of massive user base growth. They are taking weeks sometimes to upgrade the Skycoin node version, after we release a new version. We have to carefully coordinate our release and upgrade schedules to minimize exchange downtimes.
The short answer, is; we can roll out everything in a few weeks (if we had to). Everything is tested and ready to go. However, because of the exchanges are overloaded, we have to roll it out carefully in planned stages, with a months notification for any changes.
I think everything will be in place by the end of the year, but the Skywire testnet is taking a lot of development resources, so we will push it back if that means Skywire gets launched faster.
Also, then we are always improving things. So even after it “done”, its not really done. It always need more developers working on it and improving everything. We think “one second transaction are fast enough”, then someone comes in with a video game they want to put on blockchain and suddenly we need 200 ms. The demands are endless.
When all of this work is done, it will also mean that we have the best blockchain platform. So we need to have a marketing event built around this. It may not make sense to do it in the middle of Skywire launch mania, because we can only handle so many things at once.
News like this, we also have to make sure we release it into an upward market, when a lot of people are paying attention to innovations in blockchain technology. It would be wasted if we released big news or features, when people were not paying attention.
What's in store for Skycoin this year?
To many things. Everything. All at once. Its crazy.
We are opening a hardware incubator, which is the most exciting thing for me. I think we will not see the real applications of blockchain until we get blockchain into the physical world.
Where do you see this project in 5 years, where in 10 years? (What is your long term goal?)
We are moving so fast. I could not imagine that we did as much as we have, in such a short time. I cannot even keep up with how many things are in development now.
The goal this year is to demonstrate real world applications of blockchain technology. To bring blockchain to the physical world and make it tangible.
The goal in five years is to make blockchain obsolete and to create what comes after blockchain. We are experimenting with a thing we have started to call the “Fibre”. I do not think innovation will stop at blockchain.
The third generation of coins is going to be post-blockchain and want to be a leader in this area.
How long before I can buy a coffee with Skycoin?
As soon as I buy a coffee shop, lol.
When the community try to bring more people to skycoin, specially those with big money, we have to face the fact that the time locked distribution is not auditable (or it is?) is there any strategy to calm the doubts about the distribution method (the developers hold the majority of the coins/ are the only ones able to mint coins)
One of the advantages of blockchain is that all of the transaction are public. So the distribution schedule is auditable. Skycoin’s distribution is completely public. The distribution addresses are also public. So it is very transparent.
There is an api endpoint here with the distribution addresses and information updated in real time
In your blogs you are talking about the possibility of a ninja announcement that burns 80% tokens. That means it will be only 20 mil sky. So, in which circumstances devs would do that?
If we can find a closed loop, economic model for Skywire, that does not require a 15 or 20 year distribution period. Then we will burn the coins. Then the distribution would be capped at 30 million instead of 100 million.
Right now, we need the coins held aside for infrastructure investment, to grow the network and maintain the project.
There are some future components, that could eliminate the need for infrastructure fund and enable the network to be self-financing. Even if we get these components in place, what it means is that the infrastructructure fund will just allow us to grow even faster! So we might still not burn the coins.
You cannot underestimate what it will mean if we are investing 100 million dollars a year of coins into growth. This is the fuel that drives the growth of the ecosystem, so it does not make sense to “burn” the fuel. If there are more projects we can invest in, to grow faster, then we should do that.
In your opinion, what is the best exchange for buying Skycoin right now, and why? And on what other exchanges will Skycoin be listed, and when?
C2CX is good. Cryptopia is also good but withdrawals are slow.
We will be listed on larger exchanges this year, but cannot give details. We signed contracts but the exchanges grew from 1 million users to 8 million users in a few months, so their technical teams are overloaded. Listing a new coin can take 6 months after signing the agreement now. We are doing all we can to expedite the process.
Will the Kittycash platform be advertised across cat loving forums and the like?
What will the value of legendary kittys be in 2019?
People are spending 1 or 2 Bitcoin per legendary kitty now. Kitty Cash had to stop selling legendary kitties, because fifty people were trying to buy each kitty and too many people were trying to buy them at once.
When will SKY be listed on new exchanges?
We were listed on four new exchanges this month. Wolfcrypto, Next, and two other exchanges. I cannot even keep track of it.
We signed contracts with the largest exchanges, but are still waiting for technical integration and we signed contracts not to disclosure information about specific exchange listings.
The exchanges are very overloaded right now, with technical problems from user growth and also from hundreds of coin ICOs that all want to be listed at once. Millions of people per month are registering on the Bitcoin exchanges now and the exchanges are overloaded. It can be a six month waiting list for listing now, after contracts have been signed, so we are just waiting at this point. However, big exchanges are coming soon.

How to get started on GPU mining on Pizza Pool ( [Nvidia/linux/ClosedSource]

Sunday morining the 0xBitcoin Discord got a surprise from @0xPiZzA...
hi guys. i am 0x778, again! has it gone a long time and you miss me? 8^D= i wait two more weeks since last time, want to check you to see if you are ready for gpu and 0xBITCOIN. today i am ready to release Closed Source GPU Miner for everyone, works for my new Mining Pool name " PiZzA Pool " ! \o/ new pizzaminer is ALPHA software : means speed good but has bugs. Linux only OS. new pool PiZzA Pool also ALPHA but in testing now, available for your to try. credit system is counting. automatic payment, i am building it now. XD lets GO for best! i am not support Help with this software, please figure it out. i believe you can do it. PiZzA Pool going to donate 2% to 0xBITCOIN project / Infernal Toast who will make Open Source Gpu Miner in competition with pizzaminer and Prevail in Triumph. .o/\o/ when you ready, more info : :heart: Have Fun, Love 0xBITCOIN 8^D= ~~ 0xPiZzA :heart: 
GPU mining!!!
PiZzA pool -
Before we start...
Yet the miner works and I've been paid by the pool (71.17318134 0xBTC):
1. Prepare your mining rig
Download required programs:
Using this software is risky, but you can minimize the risk by planning. Ideally you want a sanitized GPU mining rig.
This means:
  • No private key!!!
  • No saved passwords!!!
  • No files you are not comfortable with losing!!!
Use this as a basic security audit if you have an existing GPU mining rig.
2. Download and Install Ubuntu
You can Google this.
I believe in you, you will figure it out. :-D
But get an .iso and use Rufus to make a bootable USB.
3. Install Nvidia Drivers
Don't download them from the Nvidia website. Use repositories instead. This guide worked for me:
Make sure you are connected to wifi at this stage. The error message will not clue you into the fact that your internet is not working.
4. Run the pizzaminer software
Details are in the README.TXT. But essentially all you need to do is run the program. Make sure in properties it has permissions to exectute. Also run each miner in their own terminal instance.
CUDA_VISIBLE_DEVICES=0 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=1 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=2 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=3 ./pizzaminer 0x0123AbC... 
5. Configure Autostart
Inside the directory where pizza miner is create a file (autostart) that is executable and contains your payment address:
#!/bin/sh xterm -e -hold CUDA_VISIBLE_DEVICES=0 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=1 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=2 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=3 ./pizzaminer 0x0123AbC... & ... 
Then from Start>Startup Applications add the following task:
Name: Autostart pizzaminer Command: autostart (browse for file created above)
7. Optimization
v0.0.3 CPU optimization
Before the CPU was bottle necking the GPU utilization in certain cases. v0.0.3 fixes this and it's stable for me. With multiple cards on a Celeron G39XX you can expect a 50%+ boost in overall hash rate.
Overclocking (EXPERIMENTAL!!!)
This command should allow basic overclocking, monitor free initialization. Honestly haven't had much success in the overclocking department. Let me know if you do!
sudo nvidia-xconfig -enable-all-gpus -cool-bits=28 --allow-empty-initial-configuration 
6. Known Hashrates
GPU MH/s MH/s MH/s
Version v0.0.1 v0.0.2 v0.0.3
GTX 970 (40 MH/s) (55 MH/s) (75 MH/s)
GTX 1050 Ti (40 MH/s) (75 MH/s) (90 MH/s)
GTX 1060 (60-70** MH/s) (100 MH/s) (150 MH/s)
GTX 1070 Ti (90** MH/s) () ()
GTX 1080 Ti (140** MH/s) () (325** MH/s)
Please tell me your hashrates to add to this table!!!
If this guide has been helpful please consider donating:

Solar powered raspberry pi bitcoin miner - Is it possible? N00b who has to do a senior project and is interested in cryptocurrency :)

Howdy. I'm a high school senior with a senior project to do. Let me preface this by saying I know absolutely nothing about raspberry pi or solar power (although I do know a bit no pun intended about bitcoin mining). Is it physically possible to make a solar powered raspberry pi (with a battery obviously) that uses a USB bitcoin miner to basically get extremely small amounts of bitcoin? It certainly does not have to rake in cash, as this is an educational project. I would like it to shut off automatically when the power supply is low, and simply resume automatically when the power increases. If this is even possible, what would be the budget on this contraption? Thanks! :)

Strange device on school network

I was using Fing to browse some devices on my school's network because I was bored and I came across a Raspberry Pi. I thought this was peculiar because one: all the students had left, so it wasn't a student device, two: because the school primarily runs all their services off google and Windows Server, there were no Linux/Raspberry Pi devices used. I look further and the device reports over zeroconf/Bonjour that it's name is "TG-REVGEN" I scan services and find it's running SSH, SFTP, and VNC. I connect over all three with the default "pi" "raspberry" logon for Raspberry Pi, but sadly none work. Over VNC, there's a password hint, which I found quite strange. It's: "Guest Harvard Vega. Giraffe April welcome." I attempt a connection externally but it doesn't work. It most likely isn't the tech department's because why would it be wireless when then can easily wire it?
I make this post because it has me quite interested. My current theory is that either a teacher or student secretly set up a bitcoin USB miner with a raspberry pi, hence REVGEN (revenue generation).
Any ideas?

Monero mining, the road to hell.

You know it started out innocent enough. One friend at work started talking innocently about Monero and before I knew it I had hooked the work PC up to Minergate and had started mining. After I day I saw Moneros slowly ticking in and felt that it needed to go faster, so I downloaded the client as well on my gaming PC at home, but I wasn't able to use the graphic card, the Moneros were still ticking in at a too slow rate.
I did some more reading and found out that Minergate was the devil, that the way to go about this was to set up my own wallet and mine using a client, directly toward a pool. First I created a web-wallet, but then I remember MtGox and all the trouble with bitcoins being lost, so I created a shell wallet on my file server at home and downloaded a few clients, compiled, compared, tuned and after a while I started to see some real Monero dripping in. I managed to get the NVidia miner up on my gaming rig with the juicy 980Ti card and that really made the difference, but I wanted more.
I work with grid solutions/high performance computing and at work we have a lab where I can basically set up whatever equipment that I want (within reason) and latch on to work's power grid. I decided to set up a dual GPU system and just leave it running in the lab area where we have the consoles and do general close proximity work to make things work in the real lab. I did not have a casing so I ordered everything I needed and after some troubleshooting (BIOS did not support the Kaby Lake CPU) I got things up and running on 2xRX480 cards, nicely hashing in on about 630H/s on each card.
In the mean time, to maximize my Monero flow I had turned every device, work and private into CPU and GPU miners, every clock tick squeezed for maximum utilization and at one point I even ran clients on useless Raspberry PIs, slow file servers and Beagle Bone Internet of Things cards, yielding no more than 3-6 H/s. It all added up, but I still needed more.
I started looking into building a real mining rig. I ordered an AMD Motherboard, more PSUs, CPU, RAM, USB risers, etc. and I got a rig frame flown in from China at a reasonable price. In the meantime I had already ordered another RX480 which were idling on my work desk while I was building the rig. The rig was being set up at my work desk, sitting next to my work PC which also was mining Monero at full capacity when I wasn't at work. GPU mining needs to be off if the system is to be used without severe graphics lag.
I had installed 2 GPU clients on my home system as well, one that really bogged down the system, rendering it unusable for anything except mining, the other setting I could easily do other work, web-browsing and such without too much lag from the graphic cards. Whenever I left for work or went to sleep I put the heavy load version on, and when I got home from work or woke up in the morning, my living room was warm and cozy, at least 4-5'C above the usual.
By now I had gathered 5 GPUs which had completely filled up my mining rig. Achievement unlocked! Although I still had some debugging work to do on it (random crashes) it still would run smoothly most of the time. The Monero is pouring in, about $10 USD worth of Monero each day, from both my rig and the myriad of fileservers, gaming and work PCs, and stupid little devices that were designed for completely different things. The value of Monero had increased from about $12 USD to $30 USD during this time, everything was with a promising outlook.
Then, yesterday it occurred to me, I did move 2 cards from the first PC that I bought, to the mining rig, which means that I could get two new cards and put into that one. So, I have just ordered myself two more RX480 (which by the way are much nicer for Monero mining than the RX580s) and as I am sitting here, having just ordered those cards, I am already planning the next step, moving the first motherboard out of the PC and latch it on to a rig and connect 2 more cards (it's a mATX motherboard with 4 PCI-e slots)
But now, I am wondering, where will this all end? Have I become a Monero mining addict? How many rigs and graphic cards do I need to finally feel satisfied? When do I get enough? And will this short term bankrupt me completely? Well, at least I am not using money on booze, drugs or hookers, but it still feels like an addiction.
Any words of advice or comfort appreciated...

Skywire - Try and censor this, I dare you.

Synth posted this recently - Why? Remember that Skywire is designed with these in mind:

1) Asynchronous.

"Asynchronous data is data that is not synchronized when it is sent or received. In this type of transmission, signals are sent between the computers and external systems or vice versa in an asynchronous manner. This usually refers to data that is transmitted at intermittent intervals rather than in a steady stream, which means that the first parts of the complete file might not always be the first to be sent and arrive at the destination. Different parts of the complete data are sent in different intervals, sometimes simultaneously, but follow different paths toward the destination. The transfer of asynchronous data doesn’t require the coordination or timing of bits between the two endpoints."


It is more flexible and devices can exchange information at their own pace. Individual data characters can complete themselves so that even if one packet is corrupted, its predecessors and successors will not be affected.
It does not require complex processes by the receiving device. This means that an inconsistency in the transmission of data does not result in a big crisis, since the device can keep up with the data stream. This also makes asynchronous transfers suitable for applications where character data is generated in an irregular manner.


The success of these transmissions depends on the start bits and their recognition. This can be easily susceptible to line interference, causing these bits to be corrupted or distorted.
A large portion of the transmitted data is used for control and identification bits for headers and thus carries no useful information related to the transmitted data. This invariably means that more data packets need to be sent.

Choco's way of understanding it:

2) Channel bonding

"Channel bonding is an arrangement of communications links in which two or more links are combined for redundancy or increased throughput. Examples include links associated with network interfaces on a host computer, or downstream and upstream channels within a DOCSIS cable modem connection."

Choco's way of understanding it:

3) Economy based on data forwarding and downloading

The new Decentralized Internet, a wireless mesh network that pays you for supporting it.

Choco's way of understanding it:

4) Will even work on low-computationally intensive CPU boards like Raspberry Pi's.

Self-explanatory. See Skyminer.

Choco's way of understanding it:

Spelling it out.

Digital transmission of 0.1 watt (20dBm) from Sweden to Australia, over 15000km using the WSPR protocol. For comparison, your cell phone uses many times this transmission power. :-)
The extreme application possible with this design means it is nearly impossible to censor anything. The best you can do is make it annoyingly slow to transmit data, you will not kill it. Skywire's uncensorable data transmission is akin to Bitcoin's original idea of uncensorable money.

FOR IMMEDIATE RELEASE: After Butterfly Labs collapses, engineers find new jobs at 21 Inc.


After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

A bitcoin miner has shipped on time. Yes, that is news. A new venture-capital backed company, 21 Inc., has released a miniature bitcoin miner that they call a "Bitcoin computer". For $399.99, you get a Raspberry Pi, an SHA-256 ASIC board, and a giant fan.
Again, this is news: normally, a manufacturer of bitcoin miners would overdesign and underengineer their equipment, or, if they managed to ship something functional, it would be so poorly engineered -- and over budget -- that it be an explosion waiting to happen and/or priced comparably to a four-door sedan.
21 Inc. has done something remarkable in the Bitcoin world: they started a company that operates like a legitimate business. They're even listed on, a company that's so strict with vendors that Nintendo was kicked off their system for not kissing enough customer ass.
Okay, enough with the praise.

This thing sucks.

The "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)

Is that all I get for my money?

Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:

How about the software demos?

It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:

What are the real customers saying?

The packaging is slick:
"This @21dotco computer came already opened..."
The hardware is reliable:
" must have lost power, which caused my SSH keys to become corrupted."
The software is revolutionary:
" will be more expensive to pay for your spotify subscription via your electricity bill, but a lot of people don't care."

I want to buy it anyway!

Go ahead. I won't stop you. Oh, and 21 Inc. doesn't accept bitcoins.

I'm 16 and I want to start Bitcoin mining

I have already ordered a Raspberry Pi 3 and I know I need to install NOOBS onto it. I've watched a few videos on making a Bitcoin mine so I know/have everything I'm going to need. However, I'm having trouble finding USB bitcoin miner. I've found this one on Amazon for $70, but I'm not sure it's the best option and I'm hoping one of you could help me out.

Mining on a raspberry pi 3, Need some pointers.

Okay guys. I have a 24 hour deadline to finish this project and need some help from the Reddit community.
I bought a raspberry pi 3, a 5 inch lcd, and this usb asic miner off of ebay. The usb miner will be ready tomorrow, but I was wondering what I can do today to make sure that I can properly demonstrate that the computer mines bitcoin.
So here are some things I need help with. I know that I will hardly earn any money, but I am not creating this project for that reason
1) What pool should I be using?
2) Will the pi be able to handle the power needed by the miner?

Low wattage hobby miner hardware?

I'm a fan of bitcoin and like to support the bitcoin by buying and holding BTC and operating a full node - a bitnodes unit that consumes a very minimal 2.5 Watts.
Just for fun I'd like to run a small miner drawing about say 20-50 Watts tops, I know this will not be profitable in any way but would like to do it anyway more as part of a hobby than anything.
I've mined litecoin in the past using a bank of 3 graphics cards drawing about 750W total and it was a bit impractical for me to be honest due to the noise and heat they generated and the uncompetitive price I pay for residential electricity.
I figure something that only requires minimal cooling and therefore has no heat and noise issues would be ideal. Maybe a USB miner plugged into a raspberry Pi? (since I already run a couple of Pis).
It would be nice to have something fairly competitive in terms of hashes/joule efficiency. I see the ant miner S7 currently leads by a wide margin with about 4000 MHashes/Joule. See Mining hardware comparison

Alternate uses for a USB Bitcoin miner?

So I have a little $20 ASICMiner Block Erupter USB miner I used to mine Bitcoin and Peercoin for a while. Unfortunately, the difficulty of mining Peercoin has risen such that it's not powerful enough to make back its electricity usage. As I understand it, a Bitcoin miner is basically just an ASIC designed to break SHA-256 encryption. With this in mind, is there anything can do with it and my Raspberry Pi (other than crypto mining, of course)?

USB Mining Project

I found an old (abandon?) project that boots Arch Linux to run a bitcoin/litecoin miner automatically using cgminer.
Wonder if and how to modify it for XMR.
I've done some simple programing before in C and played around a bit with Raspberry pi, but this Github project is a little above me.
