My first DIY bitfury solar miner.
The box under panel contains RasPi and custom single chip mining board (its heatsink is sticking out of the box).
The chip's core powered directly from the panel (Uoc=1.15V, Isc=5.5A, Ucore=0.87V), and RasPi powered from the cord.
Аfter the first half hour of mining I observed unusual high hashrate (>3Gh/s) of single bitfury chip.
Just to mention I was unable to get more than 2.9Gh/s from this chip when it was powered from buck converter (0.85-0.9V).

In an SPI chain of chips, does the OUTMOSI go back to the host, or does the return data get routed back down the chain to INMISO?
The latter. output port of the final chip doesn't need to go anywhere.

Is there anything special to be done to end a bitfury chain?
I'm trying to make one single chip being detected and used by cgminer but while it does solve test vectors with spitest, cgminer nor chainminer are able to use it for mining.
I'm assuming that outclk, outsck, outmiso, outmosi don't have to be connected for a single chip system...

Where is this "spitest"? Is it a pre-written test vector program that I missed in here somewhere? That'd help me tremendously getting a beaglebone bitfury port

Now that I'm on chainminer, I just repopulated that chip on the board, and this seems to confirm it's marginal:
What is this "chainminer" you speak of
It was announced here:
Thanks to Niko and his team for developing a nice web interface for the rPi controller.
https://megabigpower.com/images/piServer.PNG
also he put up the chainminer code on a github:
https://github.com/bfsb/chainminer
I'd love to see some community effort around improving both the piWeb front end, stratum failover options & chainminer itself...

I think I have a bad chip. It was acting strangely when I was testing cgminer hashing one chip at a time, reporting between 500 and 1500MH where all others were >2.5GH.
Now that I'm on chainminer, I just repopulated that chip on the board, and this seems to confirm it's marginal:

Holy thats pretty impressive Any news on full production/cost?
Any news on full production/cost?Like with the S-HASH design, we're not looking to mass produce this ourselves, but we're open for licensing agreements with 3rd parties to build them. It's hard to estimate a cost. It all depends on volume and what kind of deal you can make with the bitfury ASIC sellers.
Have you approached any companies yet? This looks pretty special to me
Fantastic work on those boards by the way.
Indeed.

Our (c-scape & intron) bi•fury board is hashing over 5 GH/sec.
Screenshot from BTC Guild:
Photo of bi•fury prototype board with 2 ASICs, plugged into laptop. A fan is aimed at the board + heatsink, keeping the ASIC temperature at 45 ℃, and the rest of the board (including the regulator) at 40 ℃. Core voltage has been set at 0.84V.
The extra pushbuttons, jumper, and 3 wire UART are just for testing/debugging.

Pretty sure it's a software problem.
Switched from cgminer to chainminer, and now I'm seeing >18GH on seven chips!

What are you using for spiclk speeds and bitfury clock setting?
SPI clock 500 kHz, core voltage 0.88V, internal slow osc 54 bits.
What software are you using?
