Pictures of your mining rigs!

[pontiacg5]

The USB riser cables came from China directly, I ordered them in bulk. There's really only one or two suppliers, last I checked.

There are a few guys who sell them on the forum here, you may look around the marketplace a bit and get lucky and find a local seller.

Get ready to see my crazy wires and rig ahaha

Toilet paper and cardboard boxes literally right against stacks of potential ignition sources, A++ would ignite again.

Those multiplugs are a fire hazard if you're not careful how much you load onto them. I'd check how warm the cables feel.

And on the "I built this myself", may I present a BFL single/25 that hashes at 48. :-)



Yep, that's 5 chips added on the right side. And yes, I had to build the whole 1 volt supply myself. To be honest, I'm actually kind of impressed with this one, details over in this thread.

Maybe I should get a job building these. Or testing them; I seem to be good at figuring stuff out.

So my latest procrastination had several design requirements:

- Must ventilate most of its heat to the outside (hot Australian summer at the moment)
- Must not be audible from any part of the apartment (as declared by the minister of Finance and Tribal Warfare.) outside of the spare bedroom
- Must not burn down the place if some shitty PSU cable/connector catches on fire

But first, some history... The existing solution that worked for ~half a year for my CPU miners (Primecoin/Protoshares): I had installed most of the stuff under the home entertainment unit, complete with fan intake and ventilation duct (this was when I was single, can you tell?):

At its height, there were 7 computers in there, ~500 watts of heat nicely ventilated outside. Ambient temps are often 30 deg C all day where I live so more heat from mining is not required...

Anyway, certain people found this setup in the living room unacceptable and a new solution that met the criteria above was created...

Mining box!

Home of the mining box

Since the first pics, some motherboards had died, other systems were repurposed. As a result, the mining box would house:

1x core 2 quad q6600, dual radeon 7790s
1x core 2 duo E8400, 1x radeon 5750
2x core 2 duo E7500, (CPU only)
16 port gigabit switch

Here is the power infrastructure, networking (including switch) hidden under a plane of glass. On the right are the two E7500's and in the middle is the E8400 and shitty old 5750 card:

https://i.imgur.com/EI7qYt6.jpg


The Q6600 and 2x 7790 placed on top of the glass which sits sort of diagonally:

https://i.imgur.com/5YP4hDO.jpg


As it turned out, it was very hard to cool this thing while keeping it more or less silent. Most of the things in the box were quiet, but most of the AC powered fans I had to ventilate it were too noisy. I finally tore this rotary vane (squirrel cage) fan out of an old portable air conditioner. I added a cord and switches for it. It has three motor winding taps and can run at 85, 155, or 185 watts (@230 volts). Unfortunately all of these were simply too loud. Even at the lowest fan speed it creates reverberations that can be heard from the other side of the apartment. The solution is to run it on the lowest setting, through a step down transformer that outputs @ 130 volts. This limits the total power consumption (and noise) to 28 watts. The clips on the side are to hold on the dust filter. The plastic lid placed on top of the CPU heatsink is to deflect some of the air coming down from the fan, which can make an annoying whistling noise:

The box is pressurized by the big fan, and hot air flows up through a duct to the window above:

https://i.imgur.com/nB1WvUj.jpg


Making the wooden window frame and getting the duct to stay in it was a huge pain in the ass. I finally settled on a ventilation fascia installed into the wood, which gave a point to secure the duct to. Its held in place with some reusable zipties and screws.

https://i.imgur.com/7GEIj6J.jpg


Unfortunately, as I discovered later on, making the fan silent by running it at lower RPMs reduced the flow rate too much and things were getting too hot. As a result the Auxiliary Air Accelerator(TM) was created for $9. I'll eventually cut out some metal at work that will make this duct connection and entire top of the box much neater.

The final setup as it probably will be left from now on:
*I changed the step-down transformer to a 1000 VA model so all of the motor speeds can be used if needed

There is another two 7790's and a watercooled 6870 (display device) on the HTPC, now much lonelier without its CPU mining brethren:

So numbers? The CPU mining across all of my systems makes about $8 revenue per day. Mining dogecoin across all my GPU makes about $20-22 revenue per day most day. Power cost per day @0.30 AUD/kWh is about $8 to $9. I have some outdated ASIC strapped to the cooling fans of my makeshift NAS pile which get about $0.15/day? ( ):

The end... for now...

Cables are very cold none of my cables run hot, today I will split up the rig and yes cable tie the shit out of those messy atx wires aha.

Also looking to mount everything in a spare server rack, Cheers

[N[e]wBie]

so I want to make a rig like this;
to keep it outside. What tools are needed? I have the box already, and the system, nothing else. Can I simply screw the motherboard into the plastic with a standard metal screw? Can I do this without a power drill? Will three fans like this be better blowing towards the GPUs if the case is open, and OUT if its closed? Thanks!

Was this the place: http://www.aliexpress.com/item/PCI-E-PCI-E-Express-1x-to-1X-4x-8x-16x-Riser-Extender-Adapter-Card-with/944387438.html

Here is our rig currently, adding a second machine into the chassis later today. Doing very nicely with temps running from 76-80 on the R9 290's. Had all sorts of fun with the MSI board and the risers (had to downgrade the slots to Gen1 to get it to boot) I also totally failed to get linux working (not got the linux skills sadly) Win 7 64 up and running a breeze tho. Getting about 430kh/s per card mining VTC atm. Chassis allows for 2 rigs, with a i guess enough space for 4 x cards per rig, but sticking to three per rig for now.

Rig design a work in progress, rather like the vertical mount idea with the fan blowing between the cards and board. Your design is very good and allowing a decent level of expansion, did you fabricate it yourself or build it based on existing shelving? Are you running 6 x cards on one board with 2 x PSU's?

The wooden frame isn't to bad. I should spend some time and similar.

So after yesterdays rig upload:


I have now created V2 setup






Will upload the ants soon

Much cleaner and better looking plus temps are down by 10c on average

Cheers

[klondike_bar]

Just got 4 more antminers wired up, last 2 coming tomorrow for a total of 7 antminers and a 256GH Bitfury system. - roughly 1.65 TH

Of course, I wired up the entire crate with 2 antminers and 2 power supplies, got it in place, powered on - and only one PSU works .  With no good way of removing the bad PSU, I had to cut the power lines and route them to another PSU ziptied to the crate.

[batt01]

One Asic Cube, two overclocked AntMiners and a few Block Erupters and a Rpi. I added an exhaust  fan to the Ants to help keep the temps down.  Room is now toasty warm. Pool show total of 480ghs. I have about 30 more BE's and a Jalapeno 7ghs now shown.

@duniek
what is that motherboard u using? you got so much space with 3 gpus

Looks like a DFI Lanparty board for AMD (probably Skt939?), and one of the few motherboards out there with nice spacing for three graphics cards, similar to the Asrock X58 Extreme6.

Here is my USB collection.





Also a youtube video of some of my Bitmain U1 units running.

Here is my USB collection.

Hey, we think alike, what are the two weird ones (3rd and 4th from left)?



I got the original heatsink for that BE!

Edit: to the moderators, this new image thing is broken because it doesn't cache properly!

3rd is a nanofury prototype hand made by Vs3 4th is an IceFurY
