When you run bfgminer dont you pass it information about the devices to use? like:

bfgminer.exe -o http://stratum.bitcoin.cz:3333 -u username -p password --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM4

You can then save this as a desktop shortcut or some kind of .bat to autorun on boot. Then create a duplicate of this specifying different com ports for each of your devices and different worker details.

There is probably a better way to specify this in a config file but I have forgotten how. I'm sure someone else with clearer instructions will come along.

Someone asked something similar on my build log (https://bitcointalk.org/index.php?topic=255582.20 post 37). I was doing a comparison between btcguild PPS vs btcguild PPLNS vs slush (better with slush I thought after a week). For my setup on my raspberry pi I had it to run three instances of CGminer each using different block erupters (2 each), so I had different -S tags in the script that would load up cgminer automatically on power up (but on PC you can just put this in your .exe command to run), and then each using a different .conf file with different worker and server settings. All instances worked perfectly, although there was a warning about the API being already in use but this was a non-fatal warning and did not effect mining. I am assuming the BFGMiner is written very similarly to CGMiner so a first job would be to check this but quite possible then

Does anybody know of a place for stats listing top transaction fees? - I wanted to see if we were particurly lucky in this respect

Transaction Fees 16.28387991 BTC (http://blockchain.info/block-index/406729/000000000000000fd4a3801c9df5ba3d8570e56cad29c28026d072051090e9f1)

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

I take it that you didn't have any issues running the first parts sudo apt-get update etc. maybe the site was down when you tried because it downloads the file in my browser

Hia, I am no expert but lets work through the simple things - so you have got the internet up and running via either wifi or ethernet? (did you check it out by opening up Midori)

Looks good, like the power switch idea. Post back if you use my guide and have any q's.

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:

• Set up two accounts for a pool, each with one worker, and each with a different payout address
• Run two instances of CGMiner on the RPi (you might get warning about API but that is not important), because I don't think you can have more than one worker logged in in one instance of Rpi
  Have both having a separate config file with each going to the pool but with different users and workers.

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.

Thanks for looking, Will

They're 336mhz each and I have 6, so that's just over 2gh. They are turning over about £1.30 / $2.30 per day. And in order to work out if I was making any money you'd have to know how much I paid for them!

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

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? I am envious

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. Cheers, Will

So what you are saying is anybody in the world who starts working off the block that we found here, by adding new transactions to it? Phew get it out there!

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

Easy come easy go:

I think I lucked out with that one - highest earnings on a single round so far for me! Thank you for your donations:

What he said

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.

When I went in at 18:41:00 (UK time) 31/07/2013 my total confirmed and unconfirmed was 0.17885167
in again this morning just now 06:16:00 01/08/2013 total confirmed and unconfirmed is 0.17826633

during the night the meter has been running backwards for me, and yet I don't see anything in stats in terms of invalid blocks

any ideas? We're not talking a huge amount here, but is potentially lost work during the night
