can someone post the pi image they are using for this? tried the black arrow one but reports error with mining_proxy and still doesnt work after updating it.

I made a support thread / setup guide for the black arrow bitfury 16 chip board. I'll post my cgminer setup guide later. Here's the thread:

thanks, looks like it was more my wiring than software.

If I purchased a kit (I did) from Minersource, can I buy more boards at the $40 price point?  Also, do these boards have a tendency

to produce many errors when connected in larger numbers.  I can get sub 1% out of EACH board separately, using Cgminer, but

more that 10 connected at once gives me crazy errors.  Even if I knock the speed down to 50!  I would like to connect 24 boards

to one R-pi/controller. 

Thanks!

We do see a tendency for a smaller number of errors, but not significantly. You may have a bad board in the stack that is effecting the others. You can buy as many of the boards @ $40 as you would like.

No overclocking, but as long as you buy > 13 boards, pi and controller are included.

if these were $30/each it would be a non decision but with the price of the big rigs dropping so fast it's just easier to wait and not have to 'cobble' a 1 or 2 ths system.

I have tested each board separately and logged errors.  All of them where below 3%.  When I connect 10 boards to the controller the errors stay low.

However when I connect 15, errrors are almost always above 5%.   I noticed increasing the SPI frequency from 96000 to 500000 helped.
