Pictures of your mining rigs!

Wow, people are still GPU mining?

Why wouldn't they be? I make over 2 BTC daily after converting the alts I mine to Bitcoins. While everyone else was spending money on ordering ASICs, I created a SCRYPT farm. I figure why take my army into the arms race for ASICs, I'll wait until the armies are weakened and build my army for much less money.

Pretty impressive, counted 49 cards?

Whats the noise like in there?

Because they pay for electricity
Btw pretty impressive farm, can you share your electricity specs?
(load, price and so on)

Also.. that room should be pretty hot!

.048 kw/h, 20,000 Watts

2 tons of cooling for 2 month out of the year and the rest is cooled by (2) 12" intake fans and (2) 12" exhaust fans. Room stays under 100 degrees in 90 degree outdoor temps during primetime day hours, and under 90 degrees in the evening. Cards run under 80C.

I'm over 70 cards now since the racks are full now (that pic was taken over a month ago). The noise is loud, but the exhaust fans cause the majority of the noise. It's an unmanned location, so noise isn't a factor.

Noise might not be a factor .... but fire ... everything is wood in your picture. Dried wood at that heat burns like a match.
Please make sure that you get an adequate (auto) fire extinguishing system installed. Not water based obviously!

Got my raspberry pi and block erupter mining without a hub. I know it's never gonna ROI but I'm selling my 7970 and I feel like I just need SOMETHING mining away! Plus it's a good use for the pi I've had sitting around for a over a year doing nothing.


So to do this I had to do a few things:

Drilled a 3.5mm hole in my pi case (smallest drill bit I could find) and bolted the Arctic F8 fan on with a 3M bolt with two nuts as spacers and one inside the pi case holding it on.

Made a breakout board to convert the non adjacent 5v and GND pins on the GPIO into a 3 pin fan header.

Soldered the Vin and GND directly to the USB ports and bypassed the main polyfuse.

Plastered the BE in cheap ram heatsinks (these are £1.50 for 8!)


Fan Mount:




GPIO 5v to fan header:






Direct USB power:



Finished and mining:





Future plans:


Get washers for fan mount.

Make fan shroud.

Cut ridiculously long VRM heatsink on the pi in half and put one piece on the block erupter VRM (see pic 2)

Overclock block erupter.

Yes, I'm putting Halon in my mining room.   

Barring a freak electrical issue, it's setup safely, across the street from a fire department, and fully insured.

Nice rigs. I planned on doing something similar, but the heat just became too much in my basement so I had to cut back. I would have kept going with GPUs if the heat wasn't such an issue, and think there are some fantastic opportunities right now in some of the alt coins like litecoin, feathercoin, and primecoin. Folks are so focused on the ASIC bitcoin race that many seem to be overlooking better opportunities elsewhere...

Wow 70 cards is a good haul! How many GH are you getting from those if you dont mind me asking?

Just north of 50,000 kh/s for Scrypt, with some more coming this week to put me at 60,000.

It won't last, but I'm glad I did this while everyone was focused on the ASIC race (I also ordered a 162Gh/s that won't make ROI most likely once it arrives). I also had a heck of a time with heat, but thanks to many hydroponics websites, they had a lot of information on cooling spaces. Those fans I installed with intake/exhaust, saved me about 6 tons of cooling. And after late september, the space will be under 80 degrees until May with just outside air being pumped in and hot air being exhausted.

A few questions about your setup...

1. Are you running a "best efficiency" pool like multipool, or are you manually switching all your miners to the best alt coin?
2. To check on, or make changes to the miners, do you have to remote (VNC, RDP, etc.) into each one? or do you use some other centralized way?
3. How often do you exchange mined coins to Bitcoin? Daily? Weekly? And how much time do you spend doing it?
4. Are you keeping track of HW expenditures vs. income? What is your estimation for ROI?

If we did something like that in the UK, we'd likely get raided by the old bill looking for a cannabis farm (they even use heat seeking cameras on helicopters to hunt down the hot spots in attics etc).

Since we're posting pics of our homebrew pi rigs, here's the rest of my setup.



The loose wires at the bottom connect to a second DE0-Nano, which is currently off on litecon FPGA development duty. The white bundle is serial comms connecting to my homebrew FPGA boards  here, as also do the red/green/blues at the left (GPIO bitbang programming of the FPGA bitstream). The central pcb is a opto-coupler to link the raspberry pi serial port to the DE0-Nano(s), while the right hand PCB is a PSU regulator to bypass the DE0-Nano internal regulators and supply 1.2 Volts core power (otherwise the regulators just get way too hot as its drawing 2 amps). There was a fan blowing air at the DE0-Nano, but the noise kept me awake at night, so I'm living dangerously with passive cooling (FPGA package temperature is 80C, so die temp will be around 95C. And its still giving 35MHash/sec ) Oh, and in case you're wondering the big diode between the choc blocks is dropping the incoming 3.3V power brick supply down to around 2.5V to reduce the thermal dissipation of the 1.2V regulator.

Heath Robinson and Rube Goldburg would be proud I think. Grommit too (he was the brains of the couple, you know).

1). I mine multiple Scrypt coins and have it auto switch using a new app called Multi-miner.. Check it out, it's been amazing! https://bitcointalk.org/index.php?topic=248173.0
2). Have Switched PDUs (cut turn off and on outlet for lockups), Raritan KVM and VNC so I remotely control every level. It's 14 miles away, and I only go in for hardware failures.
3). Haven't automated selling coins, and since I'm hoarding LTC a bit for speculation, the converting to BTC depends on coin. FTC I convert daily, as with most Alts
4). Yes, all expenses are tracked for tax purposes. ROI was projected at 6 months back in April, factoring in selling equipment for 30% of original cost (I could easily sell for 80% now). My ROI also assumed we'd be at 1100 difficulty by September 1st, and already over 1000 now, so it's working out much better than projected.

My two Rigs.
Top is the Mining Pumkin and the bottom is just my gaming PC with 2 760s and some soon to be OCed Erupters

awesome farm

agree that GPU mining is not dead
here is mine (upgraded version):

I agree, I have a small SCRYPT Farm in my house. Earning about 0.20 BTC converted per day with the hashing rate of 6.2 MH/s compare to my ASICs mining at 7.5 GH/s only earning me 0.07 BTC per day....

You do realize that 20,000W > 110A on a standard 120V line?
