Title: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: LaserHorse on June 23, 2013, 09:47:08 PM http://i1289.photobucket.com/albums/b517/LaserHorse/PiMiner1_800_zps7ab3c9e4.jpg (http://s1289.photobucket.com/user/LaserHorse/media/PiMiner1_800_zps7ab3c9e4.jpg.html)
The PiMiner project (http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner) was conceived as a way to turn a Raspberry Pi into a bitcoin mining host 'appliance' with integrated LCD. The project scripts currently display the following info: • Hashrate • Error % • Share data • Pool address & user name • Network difficulty • Mining duration / Uptime • Exchange rate via MtGox Full tutorial available here: http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner The tutorial contains information which should be helpful to anyone interested in mining with Raspberry Pi (even w/o an LCD, etc); including links to getting started with Pi, network setup, logging in via ssh, etc Note: The tutorial example uses Block Erupter USBs, but minor software changes should allow use with any USB miner compatible with cgminer v3.1.1 New in v1.1: • Added mining auto-start after boot (see tutorial for setup (http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/configure-auto-start)) • Time format changed to dd:hh:mm • Abbreviated large share count (ex. 12300 == "12k3") • Revised error % calculation: 100 * HW / (diff1shares + HW) • Added MtGox last, high, & low price (currency can be changed in PiMinerInfo.py) • Removed cgminer data logging (was appending nohup.out) • Misc. tutorial revisions/clarifications http://i1289.photobucket.com/albums/b517/LaserHorse/PiMiner-angle-800_zps725d1c19.jpg (http://s1289.photobucket.com/user/LaserHorse/media/PiMiner-angle-800_zps725d1c19.jpg.html) Feel free to make suggestions as to what you'd like to see added, or additional details to include in the tutorial. Also, If you build this project - please share pics of your setup!

Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: Red_Wolf_2 on June 23, 2013, 10:58:10 PM If you've got room on the bus, why not stick an RGB LED in there for instant status observation. Red for bad, blue for something, green for good, orange for warning (say if one or more asics isn't happy), etc...
Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: LaserHorse on June 23, 2013, 11:58:36 PM If you've got room on the bus, why not stick an RGB LED in there for instant status observation. Red for bad, blue for something, green for good, orange for warning (say if one or more asics isn't happy), etc... Plenty of room on the i2c bus - LED could def be handy. Alternatively, could just use an LCD with an RGB backlight and change backlight color per status. (The LCD in the pics above is actually RGB, just set to green) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: JLM on June 24, 2013, 03:12:54 PM Sweet.
I´ll try it. Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: cchan on June 24, 2013, 03:27:23 PM Cool
Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: hotwired007 on June 24, 2013, 03:48:20 PM Brilliant project! If only ASICMiner drops the price for their USB hardware ... havent they just dropped them? Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: forum2005 on June 24, 2013, 04:06:07 PM interesting project... all in one.

Was looking into putting an lcd shield on myself, but was after more graphical display of my cacti graphs...as I graph the cg/bfg miner api outputs Pi's work well with the fpga's too :D Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: erschiessen on June 24, 2013, 04:23:20 PM This is so sweet.
I would like to build two. One for K1's and one for K16's.

Another pi miner, my mini rig []http://anonymouse.org/cgi-bin/anon-www.cgi/http://img209.imageshack.us/img209/5761/usld.jpg[] is this not a bit expensive now as the FPGA board does around 5-6Mhash for 70 and the USB Asic does 333 for around the same? (based on 0.99 BTC) (GBP prices) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: billotronic on June 24, 2013, 05:12:12 PM this is UBER sexy!
Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: Bitcoinorama on June 24, 2013, 06:19:13 PM Very cool, love your anonymous Tor Pi project as well!
Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: MWNinja on June 24, 2013, 06:24:54 PM Cool project, I've added a few raspberry pi's to my collection of toys too. That LCD is really trick, but the thought of having to solder is a bit off-putting. It would be really cool if they were sold in a more "complete" state. Also I would love it if adafruit would accept bitcoin payment!

Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: LaserHorse on June 24, 2013, 11:22:01 PM Thanks all - appreciate the feedback.
Assembled LCD kits are not currently available - but I will post here if they become available. In any case - soldering is fun! No, really - I quite enjoy it myself ;) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: sdminer on June 26, 2013, 08:26:01 AM how many usb block erupters can the rasberry pi handle?
it has two usb connections, so can I hook up 2 x 10 port hubs to it?

Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: tom_o on June 26, 2013, 10:04:27 AM Cool project. Wish I could afford to waste money on block erupters, here's my piminer running scrypt, only several orders of magnitude slower.

Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: evilscoop on June 26, 2013, 10:38:57 AM unless yer overclocking, in an open case, with a fan....a cpu heatsink is useless on a pi...
Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: tom_o on June 26, 2013, 10:41:41 AM can't quite tell but have you put a heatsink on the CPU? Yeah runs at 64.8 even with that! 975 core/475 cache/500 ram at 1.35v. Gonna reformat it soon and make it into a lil VPN/fileserver and send it off for free colocation (http://www.edis.at/en/server/colocation/austria/raspberrypi/), running it as a miner is a bit pointless at 0.48khash/s. Stock speed is normally 0.33khash/s!

The 700Mhz ARMv6 will become the bottleneck before 127 USB devices I would have thought. Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: hotwired007 on June 27, 2013, 12:33:04 PM apparently you 'can' overclock the CPU - i dont know how or to what value - i'd definately investigate cooling - as i've seen people say they've over clocked to 800mhz
just googled and found this: http://www.jeremymorgan.com/tutorials/raspberry-pi/how-to-overclock-raspberry-pi/ 1000Mhz and much improved RAM speed? I think thats a win BUT i'd definiatly want a cooler on the chip ;) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: tom_o on June 27, 2013, 12:44:26 PM apparently you 'can' overclock the CPU - i dont know how or to what value - i'd definately investigate cooling - as i've seen people say they've over clocked to 800mhz just googled and found this: http://www.jeremymorgan.com/tutorials/raspberry-pi/how-to-overclock-raspberry-pi/ 1000Mhz and much improved RAM speed? I think thats a win BUT i'd definiatly want a cooler on the chip ;) Trouble with that is that overclocking often corrupts the SD card requiring a complete reinstall. Gonna be a bit of a pain if your miner goes down cause of this, mine is at 975 core/475 cache/500 mem with +0.15v Heat shouldn't be too much of an issue; it only gets to 64 degrees even with a little aluminium ramsink and a sealed plastic case (see top post on this page) after 3 days of LTC mining on the CPU. But I certainly won't run it this way for long! When I send it off to the datacentre it'll definitely be back to stock - not worth risking it; the performance is so low anyway, even 30% more is still really slow! Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: Rotorgeek on July 06, 2013, 02:33:02 PM Ask here for troubleshooting help? If not I'll edit this out to keep your post clean.
I ran through the Adafruit tutorial with both the Raspbian and the Occ distros with the same results. I get to the part where you start cgminer and then PiMiner and nothing seems to happen. The LEDs on the USB sticks stay solid and the LCD says "no connection to cgminer" http://imgur.com/M8u95D8 Thanks Rotor Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: LaserHorse on July 06, 2013, 10:16:59 PM Ask here for troubleshooting help?

Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: crazyates on July 06, 2013, 10:36:41 PM You can OC the rPi all you all you want, it's still going to be slow. It's an ARMv6 CPU. They've been using ARMv7 for years now, and ARMv8 is coming out in the next year or so (gonna be sweet!). That's like OCing a PIII to compete with an i3.

Yea 2 usb block erupters miners they showed as usb0 and 1. Edit: same ones from the tutorial. The also work fine on my PC, so I know it's not an equipment problem from that side.

Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: LaserHorse on July 06, 2013, 11:02:14 PM Also - please ensure you're using a USB hub which is compatible with the RPi.
As a general rule - avoid USB 3.0 hubs! a list of verified compatible hubs can be found here: http://elinux.org/RPi_VerifiedPeripherals#Working_USB_Hubs Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: Rotorgeek on July 07, 2013, 01:22:02 AM Yea 2 usb block erupters miners they showed as usb0 and 1.

Occidentalis this time but I tried Raspbian and had the same problem. As far as the USB hub, I have used it for several things, and never had an issue. I'll try it without the hub and 1 miner. Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: LaserHorse on July 07, 2013, 01:44:36 AM Occidentalis this time but I tried Raspbian and had the same problem. As far as the USB hub, I have used it for several things, and never had an issue. I'll try it without the hub and 1 miner. And it's a powered USB hub capable of supplying a full 500mA to each port? Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: Rotorgeek on July 07, 2013, 02:58:27 AM Occidentalis this time but I tried Raspbian and had the same problem.

Yea the Hub is on the list. Trendnet TU2-700. It has a 2a power supply. Oh yea I remembered I cant try it without the hub. No power in the main USB header. Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: LaserHorse on July 07, 2013, 03:21:26 AM hrrrmm … possible you have another instance cgminer running in the background?
Your best bet is to reboot the Pi and try running cgminer normally (not in background) using: sudo ./cgminer-3.1.1/cgminer --config /home/pi/cgminer.conf -S /dev/ttyUSB0 -S /dev/ttyUSB1 If cgminer runs into an issue, it should display an error. Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: Rotorgeek on July 07, 2013, 04:00:32 AM Guys thanks for all the help, I got it fixed.
Someone asked me for a screen grab of the .conf file and when I was editing out the login info I noticed something. The instructions said Update the below template with your mining pool credentials by replacing "PoolAddress:Port", "UserName.WorkerName", and "Password" with your info, then copy & paste into the nano editor: Well I din't verify it transferred over properly. ::) There were some line break errors. I fixed those and it's up and hashing away. Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: LaserHorse on July 07, 2013, 04:03:18 AM excellent :)

Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi Post by: howzbit on July 09, 2013, 09:08:55 AM Quick question:
I'm planning to run 30 usb miners with the PiMiner, could I hook up 3 of these 10 port USB hubs (http://"http://www.amazon.com/Aitech-Adapter-backward-Compatible-aluminum/dp/B009NESU4M/ref=sr_1_13?ie=UTF8&qid=1373360761&sr=8-13&keywords=anker+usb+hub") (RPi non-compatible) to say 1 D-link hub that is compatible for the RPi?

Then press and hold the up button to launch cgminer with the predefined config file? The bonus would be still having the ability to SSH in independently and see the output from cgminer.
P.S. I also think you should come up with a way for people to mine on a schedule and be able to set aside time to mine (say thanks) to you for a given period of time per day/week, like cgwatcher does. Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: LaserHorse on July 12, 2013, 03:45:19 AM So I was wondering if there was a way to launch Pi.Miner form a "autorun" script when the Pi boots? Then press and hold the up button to launch cgminer with the predefined config file? The bonus would be still having the ability to SSH in independently and see the output from cgminer. The tutorial now describes how to add auto-start and the scripts have been updated to support this functionality. This method starts cgminer up as well. Unfortunately, I haven't been able to run cgminer as a background job which can then be brought to the foreground. Whenever I tried, cgminer just stops while in background - this is why I ended up using nohup. I'm open to better solutions, of course. P.S. I also think you should come up with a way for people to mine on a schedule and be able to set aside time to mine (say thanks) to you for a given period of time per day/week, like cgwatcher does. Interesting, but would need to be 1000% bulletproof/bug free - don't want to risk messing with folks' income! In any case, my address in in my sig :) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: MineForeman.com on July 12, 2013, 04:03:37 AM I haven't been able to run cgminer as a background job which can then be brought to the foreground. Whenever I tried, cgminer just stops while in background - this is why I ended up using nohup. I'm open to better solutions, of course. I don't know what you are using for init there are a few ways around it, if your using something oldish like SystemV (it has the /etc/init.d file structure) I have used this method a few times with limited success;- http://askubuntu.com/questions/257808/how-can-i-use-init-d-or-some-other-method-to-run-a-screen-script-on-boot-up/ The issue with SystemV is that it is brain dead when it comes to monitoring processes and if the miner dies in background its dead. You can do some sort of bash loop but its not ideal. Id your using a more modern distro that has systemd instead everything gets easy, use this;- Code: [Unit] And systemd will baby sit the process for you, you can even switch too it (screen -r) kill the miner and get dumped out and when you look at your process list it is still there ;) .

For some reason the installed USB controller can't handle very well those hubs made with two cascaded hub internally.

The list of colors is defined starting at line #19: Code: self.col = (self.lcd.ON, self.lcd.OFF, self.lcd.YELLOW, self.lcd.OFF, If you'd prefer to only use green, you can replace those 4 lines with this line: Code: self.col = (self.lcd.GREEN, self.lcd.OFF) EDIT: you'll also need to change line #51 in "PiMiner.py" from: Code: lcd.backlight(lcd.ON) Code: lcd.backlight(lcd.GREEN) Just remember to keep the indentations as seen above, or python may bite ;) The only other LCD function which can be controlled is the display contrast, which can be altered using the onboard potentiometer (http://learn.adafruit.com/adafruit-16x2-character-lcd-plus-keypad-for-raspberry-pi/usage#adjusting-contrast) Hope that helps!

My Pi Miner has been running great for the past week with 9 Erupters. But, I'm having a problem adding more Erupters to it and hope that someone may be able to share some guidance.

Thanks for the ideas and feedback. To answer your question - you are correct, the hubs are not in series, but rather connected in a hub/spoke style. (RPi -> Hub1. Then Hub1 connects to Hub2, 3 and 4 directly.) I did not try specifying ttyUSB13 & 14, although that is a great suggestion.

This method starts cgminer up as well. Unfortunately, I haven't been able to run cgminer as a background job which can then be brought to the foreground. Whenever I tried, cgminer just stops while in background - this is why I ended up using nohup. I'm open to better solutions, of course. Have you considered using "screen" instead of nohup? This should allow you to watch the cgminer output when you log in via ssh, but I am not sure if/how you would make it start automatically at boot, nor have I actually tried it. Here's an interesting link explaining the differences between nohup and screen: http://www.52nlp.com/nohup-and-screen/ On a side note: I just switched over my BFL jalapeno from an old laptop to my RPi and following these instructions I was able to get things up and running just fine! Awesome tutorial! :) A few comments that may help others:
Keep up the good work! :) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: Blackwolve on December 18, 2013, 09:06:28 PM Requst/Help:
Hi, i want to monitor an usb hub on a PC via network because this hub deliver USB3 for the Twin Fury (upto 900mA). USB3 is not supportet with this hub on the rpi, so i need to take this option. The quick`n`dirty was to change the s.connect ((host, port)) to s.connect (('192.168.178.xx, port)) but it is no well modification. Have you ideas how i fix it well or is there a feature i didn't see? Greetings :) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: cs2000 on January 04, 2014, 09:59:27 PM May be a long shot here, but ive just upgraded from BlockEruptors to the new Bitmain Antminer U1's. This meant needing to change from CGminer 3.1.1 to CGMiner 3.8.5.
Sadly, my screen now just says 'MHS av' 'MHS av' Im guessing CGminer changes its API or something from the 2 versions. All the other functions still work such as miner & pool name, bitcoin price, network difficulty and the devices screen, just not the most important one showing the hashing rate and the Accepted, Rejected, HW Error stats on the first screen. I don't really know Python, but I understand that the "fault" lies with the PiMinerInfo.py file (https://github.com/adafruit/PiMiner/blob/master/PiMinerInfo.py) Wonder if maybe the project author, or some other kind person could assist. Perhaps its worth creating an updated version of the tutorial, it seems as though its been hugely successful, tons of people use RPI's as mining controllers, just would be nice for it to work with the newer CGminer versions and seeing as block eruptors are getting more and more obsolete, maybe its time! Would be a shame for me to have no use for the adafruit screen, that tutorial was the only reason I purchased the LCD plate! Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: chadgroover on January 06, 2014, 05:01:52 PM Another guy here who bought an Adafruit 16x2 display on the basis of how cool it looked in the article!
Unfortunately I'm also at a bit of a standstill in getting the display working alongside some new Antminer U1s as per this post - https://bitcointalk.org/index.php?topic=390929.msg4345581#msg4345581 Would be cool if someone could take a look at some point... I'm happy to be a guinea pig if needs be! Not sure if this is of any relevance, but CGWatcher can connect to the API listen port on my Pi without any issues, but doesn't display average hashrates... Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: MWNinja on January 06, 2014, 06:02:25 PM Just wanted to drop in and mention that PiMiner comes pre-installed on the Bitcoinpi.org distribution.

Would be a shame for me to have no use for the adafruit screen, that tutorial was the only reason I purchased the LCD plate! I am having the same trouble as you. I also have just purchased a Bitmain Antminer U1 miner to test before I set up a proper rig with my RPi. I also just assembled the Adafruit I2C 16x2 LCD plate, great bit of kit and only took 30 mins to assemble and I'm no expert, so those not liking the thought of soldering anything give it a go! Anyway I installed the latest version of cgminer (3.10.0) but following the tutorial on Adafruit, I run it using the example cgminer.conf file and the LCD plate works just fine and displays all the info correctly. However, my Antminer was only hashing at around 700 MH/s, but it's rated at 1.6 GH/s, up to 2.2 GH/s overclocked. The official install of cgminer does not to my knowledge have the ability to set overclock parameters for my device as it does not have the proper bit main drivers. For those I looked at two different sources which use a "patched" version of cgminer 3.8.5 with the bit main drivers. I build and configure it fine using the --enable-bmsc option instead of the --enable-icarus option as per the tutorial. I edited the cgminer.conf file to replace: Quote "icarus-options" : "115200:1:1", "icarus-timing" : "3.0=100" with: Quote "bmsc-options" : "115200:20", "bmsc-freq" : "0981" Now when I run this 'forked' version of cgminer with the bmsc options enabled, the display just shows: Quote 'MHS av' 'MHS av' I'm pretty sure it must be something quite simple that requires a little editing of the python scripts, but I wouldn't know what at the moment and it's been years since I scripted in python!! :-\ Would be great to hear from the projects author. :) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: OliRS on January 21, 2014, 10:46:49 PM Well after a lot of reading and searching around I found this thread, and this post in particular: https://bitcointalk.org/index.php?topic=390929.msg4379693#msg4379693
The short version is that the AdvancedStyle and bitmaintech versions have alterations to the API which stops the functionality of the Adafruit LCD screen. The version below does not. After installing the repo in that post (https://github.com/fractalbc/cgminer) I now have full bitmain support and the I2C LCD screen is functional again :) Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: RemoteBC on February 03, 2014, 07:47:58 PM To resolve the 'MHS av' 'MHS av' problem edit the file PiMinerInfo.py ...
nano PiMinerInfo.py Change line 143 which shows s2 = 'avg:%s' % self.hashrate(float(d['MHS av'])) return [s1, s2] to this if ('MHS av' in d): s2 = 'avg:%s' % self.hashrate(float(d['MHS av'])) else: s2 = 'avg GHs:%s' % float(d['GHS av']) return [s1, s2] Title: Re: PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1] Post by: Sp00n1980 on March 05, 2014, 04:53:32 PM Hi i am having a slight issue with piminer, i am running minpeon 0.2.4.4, with bfgminer3.10.0
