Individual sales were never MGP's priority.  He had his big-time buyers/investors.  Dave just let us piggyback onto the hardware sales.  This was known from the very beginning and shouldn't be a big surprise.  Besides, there are many other miners to chose from now.

I'm personally running over 1.5THs of Bitfury boards and love my fickle little buggers.  But I'm much more pleased running my KNC and BitMain machines.  I don't have to worry about wiggling and swapping boards and constantly restarting.  What you don't see in the video of Dave's datacenter is the army of interns running about wiggling boards and writing new SD cards, lol.  Oh, and running to the store for new supplies of crappy rPi's.

I just wish the stratum proxy worked as failover (if primary pool fails, go to backup, so on), instead of splitting work.

True enough about the sd cards, sandisk + proper shutdown and they never seem to corrupt. I've yet to have one flake out on 12 rigs. The wobble thing is a very fair criticism though. Never should've been set up with that silly connector.


Just chuck chainminer and that proxy and run cgminer.

I second that. I have a V3 m-board and V2.2 h-cards. I just keep some fans on them, make sure the cards don't wobble and they're good to go. I just wish the stratum proxy worked as failover (if primary pool fails, go to backup, so on), instead of splitting work.

All of my hcards are v2 and running cgminer. Just nano driver-bab.c and change this:

#define BAB_SPI_SPEED 96000

to this:

#define BAB_SPI_SPEED 625000

run make again and you're gold.

These options can be passed to cgminer on startup:

--bab-options <arg> Set BaB options max:def:min:up:down:hz:delay:trf

As mentioned above bfgminer also works with --enable-bfsb, but cgminer autotunes bitfury, uses far less of the rpi's weak cpu, and runs much better imo.
