Yes, 'german engineering' if that helps. ;-)
My main reason for building the PCB - is avoiding the Risers fire hazard fun and all the cables.

The PCB looks like this:

Yes, you still need a MB/CPU/Ram. ;-)

The PI is just to remote control the Rig and measure the Wattage. One PI can mng. several Rigs.

Gauging interest: 6 GPU 19" Backplate with direct connected PSU.

I'm just gauging interest.

I have a custom Backplane that

  • fits into 19"
  • can mount up to 6 GPUs
  • powered by plugged in 1500W Plat 94% PSU (no cables between PCB and PSU, direct connected)
  • it has 2x8PINs on the PCB per GPU Slott, to draw extra Power for the external PCIe GPU, close by the GPU - so all cable length are short and identical
  • is connected via USB 3.0 Cables to any 6 Slot Board (like the usual Risers)
  • has the option to connect a picoPSU via Board
  • has the option to remote control via rasperyPi (on/off & Output Wattage mesaured)
I wonder if others would want such a package and would appreciate some offers via PM. It would include

* 1500W Plat 94% PSU
* Backplate
* USB Cables
* PCIe external GPU power cables 6x (2x 6+2) splitter cables

I don't think you understand the economics. ;-)

"secure" also means that you can't see anymore what the miner is sending - you now need a lot of trust that there is nothing hidden. this might work for claymore - but other will jump the ship and now you also have to trust them - before you could check it easily.

@Spotswood

Got any picture how the drop-in frame would look like?

@mrb

thanks, I got around that problem. I run into

Code:
DEBUG:asyncio:poll 573.300 ms took 0.016 ms: 1 events
DEBUG:asyncio:process 21691 exited with returncode 1
INFO:asyncio:<_UnixSubprocessTransport pid=21691 stdin=<_UnixWritePipeTransport closed fd=17 closed> stdout=<_UnixReadPipeTransport closed fd=18 closed>> exited with return code 1
DEBUG:asyncio:poll 563.276 ms took 0.014 ms: 1 events
DEBUG:asyncio:process 21692 exited with returncode 1
INFO:asyncio:<_UnixSubprocessTransport pid=21692 stdin=<_UnixWritePipeTransport closed fd=19 closed> stdout=<_UnixReadPipeTransport closed fd=20 closed>> exited with return code 1
INFO:asyncio:poll 999.912 ms took 1001.039 ms: timeout

I can run the solver manual and it seems to work. Is there an easy way to see the output/error of the solver so that I can keep debugging?

Weird. Enable verbose or very verbose ("-v" or "-v -v") mode and you'll see the stdout/stderr output of sa-solver.

Thanks, only tried -v. I guess it's then related to bytes.hex throwing an error - and I replaced it with binascii.hexlify - I can't find the documentation to bytes.hex.

Code:

I guess you know, in case you dont: the sum of 'Your payments' does not equal 'Paid'.
