Title: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc Post by: willinliv on July 13, 2013, 02:10:30 PM Objective The objective of this project was to put together a Raspberry Pi controlled Block Erupter USB mining rig using CGminer, that is contributing to a mining pool (in this case Slush's mining pool https://mining.bitcoin.cz/), with enhancements that make it headless, with automatic log on and start up, whilst being accessible via VNC. There are already some very good tutorials out there (used here), but I found that each of these had slighlty different enhancements of no interest to me, which meant that their specific commands were not ideal. So this is my attempt as muddling through things, interfacing different solutions together to get what I need, and troubleshooting problems as they arise using online sources. I hope others find this walkthough useful, I am sure that you'd be able to find these solutions for yourself, but I thought it might be useful for others who maybe are less confident or don't know the right search terms to put into Google. Plus it's a record in case I forget should I need to recreate it. If you do find this walkthrough a timesaver, and something that gets you up and running, you might like to buy me a shandy or two by tossing me a few milibits: bitcoin:1PhtdmAhwUB2ywGiYGEYHLY7ponXykKfBY (bitcoin:1PhtdmAhwUB2ywGiYGEYHLY7ponXykKfBY) http://s22.postimg.org/ou7ozavep/miner.jpg (updated image 1/8/13 - everything is fixed on a heavy stand that provides a nice volume of air underneath. There are two Arctic Breeze mobile fans in there too) As pointed out by J35st3r, the version of CGMiner that the tutorial below get's you to install is version 3.1.1. Apparently (according to the Adafruit tutorial) http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/install-cgminer the most recent version 3.3.1 has problems addressing the USB devices under Raspbian. But I'd be interested in trying it out sometime Sources
Equipment
Prerequisites
Instructions Step 1 - Prepare the Raspberry Pi
Now with Cgminer installed, and the config file setup, how do we actually run Cgminer for the first time just to check that everything works? Step 2 - Initial check of hardware Here we need to bifurcate slightly from the Adafruit tutorial, because they want us to use PiMiner using their LCD Raspberry Pi shield, which is nice but not what we are after.
Now hopefully you should see CGminer starting up, then connecting to your pool, and then starting to receive and send work (Accepted blocks). If there are any problems then check things such as your cgminer config file, by retracing your steps. http://s17.postimg.org/k34h33c1r/cgminer.jpg Step 3 - Set up Auto-login and autostart of Rpi and CGminer Next up, to set it so that the Raspberry Pi automatically starts mining when the Raspberry Pi is turned on, without any intervention. This means that if there is a power cut it comes back online unaided, and also we can do away with the keyboard and mouse and screen. You can set it so that it mines without having to run through LXDE (loads CGminer directly at the bash), but you lose the ability to use VNC, and whilst you can use SSH to control the computer there are disadvantages to this which I will come on to in the next section. There did not seem to be any advantages in hashrate one way or the other, so do it like this.
That means that we can now get rid of the screen and keyboard, and locate the machine somewhere remotely, but what about if we want to be able to remotely access the machine and update it's settings in some way? Step 4 - Setting up VNC access This is for controlling the Raspberry Pi remotely through another computer and the network rather than having to use a monitor, keyboard and mouse directly on the Raspberry Pi. There are two options put forward in the tutorials, neither work well enough for what we need:
The trouble with both of these is that when you login via these means it creates a second and new concurrent user session, so you can't see what the original one in terms of seeing what is the current session/desktop is doing. This is clever stuff and a fundamental basis of Linux, but no good when you want to dip in every now and again to see how CGminer and the block erupters are getting on.You need to have access to the actual session, not have create a new one.

As a heads up for any newbies reading this, this is the latest version that supports the -S parameter. More recent versions expect to communicate directly with the the USB driver, so the setup procedure is quite different. Perhaps you would like to update your tutorial with this information?

Thanks for your suggestion, and I just put a note about this in the original post. I'd be interested to see the command for running block erupters under linux for the most recent version 3.3.1. Adafruit did say there was a problem with this under Raspbian, but that might just be because they were trying to use -S tags.

I only mentioned it just in case someone downloaded the latest cgminer instead (like not everybody reads the instructions in full before starting ::) ). I had a scan through the cgminer support forum, and it looks like its best to stick with 3.1.1 for now vis https://bitcointalk.org/index.php?topic=28402.msg2632152#msg2632152 (lead developer recommends 3.1.1 as newer versions are unstable on RPi). Title: Re: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc Post by: willinliv on July 15, 2013, 06:50:56 PM Great thanks for looking for confirmation on that point, and again for raising it in the first place!
To answer the other commenter, with 6 erupters at just over 2gh/s it's making about 0.04BTC per day at present but I can't realistically expect to see any ROI financially given increasing hashrates and difficulty. Title: Re: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc Post by: 40-Pin on July 15, 2013, 10:37:32 PM I got two Pi boards myself, they are a lot of fun to mess around with. I have to ask the question though... why would one not use a 1 foot usb extension cords on each port of the hub to keep the Erupters farther apart? Hell could take a block Erupter shell off and vaccum seal all the PCBs and the exposed usb parts and just lay them in a few buckets of water, might melt the plastic but who knows! Iunno fun stuff :P

Hell could take a block Erupter shell off and vaccum seal all the PCBs and the exposed usb parts and just lay them in a few buckets of water, might melt the plastic but who knows! Iunno fun stuff :P Yes I thought about that (the extension lead thing) and I have heard of other people using these - I just decided it was more trouble than it's worth. The hubs nicely arrange the erupters for the fan to blow over them, I think it's important to have theit heatsinks facing upwards for the heat to convex (?) off of them. I have also fitted those raspberry pi heatsinks to the be chips (on the underside), and they heat up considerably so must be doing a good job. It's surprising effective a fan is at colling down those heatsinks. Having said that I don't have the fan running at night, and some days too (and it's warm here at present) and I haven't noticed any increas in Hardware errors by having the fans off, if anything it's slightly lower by a smidgen, but we're only talking 1.002% as opposed to 0.998% errors. On the raspberry pi, I now have three - one for running Xbian to play films (http://youtu.be/G2-eUrGbl0I (http://youtu.be/G2-eUrGbl0I)) from my bittorrent directories on my PC, this one for mining and another as kind of a testing one. Really versatile and keeping a lot of people very happy!

Anyway are you only using the fan to cool it? Title: Re: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc Post by: willinliv on August 01, 2013, 03:59:43 PM Yes just using two of those Arctic Breeze mobiles (the one without the stand). Seem to do a very good job at keeping it cool. I did actually fit heatsinks onto the chips (on the other side from the preinstalled large heatsinks). Lots on ebay, and the fans hit the erupters from that side so the ridged heatsinks I installed keep nice and cool. I can't say it makes anything run faster, probably more stable though and may last longer until I sell them.

Thanks!

Or is it simply a space/cost saver? Thanks! Using a Raspberry Pi is definitely a space/cost saver. Compared to a PC, its a fraction of the size, costs $25/$35 for 256MB/512MB models respectively, and uses much lower amount of power (5V micro-USB charger). Things like heatsinks and fans add a little bit of cost, but definitely improve the performance (I know this from experience). If you have an old PC layout around, you could certainly use it. Over time the extra energy costs will definitely add up though.

Over time the extra energy costs will definitely add up though. I'll add to that that it is also a discrete package, nice and small to hide away somewhere. And also with the way I have set it up, I have every faith (touch wood) that if I had a power outage/cut it would happily turn on, boot up and start mining all by itself. Certainly a lot more confidence that it won't BSOD or someother reason why it shuts down and then doesn't come back up. Very robust I'd say Title: Re: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc Post by: uletter on August 05, 2013, 10:32:07 AM Going to fall in love with this things, are we can mining using raspberry pi model a?

Hi yeah I should think so, I greatly assume that no difference in Ram or speed (or if there is that it wouldn't cause any hassles), the only thing is that you'd have to get the wifi up and running as model A doesn't have ethernet I think? I think this is pretty easy to so but you might find it useful search google or the raspberry pi foundation for a list of known compatible usb wifi receivers. There are loads of instructions on line, but if you run into probs or need more info, post back to here and eventually I check here again. Thanks for taking a look.

Looking forward to my bitfury rig ;D Yeah that's the only thing putting me off upgrading (plus no money ;) is that any bigger miner I would really still like to have control of the computer part of the miner. Look at kncminer or anything like that, lots of gigahashes but you have to use the linux board that comes built into it to control it. I like tinkering with my pi - guess that's the difference between a hobbyist and an investor. Anythink I think the bitfury works through usb?

Wondering what do you do if you have used the 2 usb ports on the pi. Can you chain usb hubs or is there another trick to it? Hi, for my setup I have a 4-port powered hub (2.5Amp power adapter for each), and each of these hubs plugs into 1 of the usb sockets on the rPi (I don't need a keyboard or mouse or whatever because I have it set up to be controlled over the network). If I had to plug in a keyboard I have a spare socket on each of the two hubs because I have 6 block erupters instead of 8. If I wanted to get more block erupters then I would buy another hub and hope and pray that this would daisy chain on from one of the hubs, but from what I have read this can be iffy with an RPi. best of luck Title: Re: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc Post by: willinliv on August 08, 2013, 07:30:54 PM Still make no money on this. 600 MHZ is not enough They're 336mhz each and I have 6, so that's just over 2gh.

Could you just use different workers? Is it safe to get worker usernames and passwords from other people (for yourself and them) if you want to mine for them? First and foremost I'm no expert at this, but as a professional troubleshooter my suggest is below. I think you are correct but to be sure If you wanted to have the earnings of one miner sending to one address and the earnings of another (lets say block erupter) sending to another address, assuming that you are mining via a pool (and from my experience that would have to be Slush's), what I would do would be:
I am currently comparing slush vs btcguild pps vs btcguild pplns weekly payouts, and have written some personal documentation on the processes, currently up to top of head with a dissertation but if I get a chance I'll update the OP with some instructions about running multiple instances with different block erupters.

useing all equipment including raspbian from the tutorial. I tried saterday night and Sunday morning. I so pose the site could have been down for quite a while and will try again after work. read somewhere a time out setting exists and is defaulted to 900 seconds but my attempts timeout much quicker than that. *Update:* problem resolved- I guess their site was down all weekend. worked right away this afternoon. Now I have an error input/output when starting cgminer perhaps because i don't have the lcd keypad kit connected yet. still waiting for it in mail. Title: Re: Walkthrough: Raspberry Pi/Block Erupter mining rig setup with autostart and vnc Post by: willinliv on August 13, 2013, 10:35:05 AM perhaps because i don't have the lcd keypad kit connected yet. still waiting for it in mail. I don't have one of those either - but I do actually have the lcd coming through the post too, but I won't get a chance to solder it up for a few weeks yet. When you connect the lcd panel I'm not sure but I don't think you would have to change the settings to call up CGminer that I wrote (if you have been following them also). You'd have to follow the PiMiner steps of the Adafruti tutorial though. I think that CGMiner provides an API port on the computer and in some way the PiMiner links up to that port to broadcast information and provide some control. But I think that API runs independantly of any settings that you apply - so hopefully nothing has to be changed. I am enjoying this work, although I am very ominous about the release of the 400gh chips, apparently there was a 100TH surge on the network yesterday and people thought it might have been KNCminer doing some testing. So the next few months could be bad news for these, I was considering selling them on ebay whilst I still had a chance to mitigate a bit of the losses, but I figured that I wouldn't get that much for the number I have (6) and to have a 'poker in the fire' would be more interesting than not to have. Lets say for example that shipping by all these companies are put back a few months/years as with BFL - here's to hoping anyway! thanks |
