There are still 15 Gridseeds in stock, this will be all we have for a while so get 'em while we got 'em.
Easy Mining Update:It seems we have an unstable rig. I am trying to narrow it down to which one it is, you will notice on coinshift our rigs are being separated into workers according to the color of their rapsberry pi's case.

So... we have teal, clear, and
naked (poor guy doesn't have a case!) Edit: Naked was the culprit, changing out the Pi to see if it has any affect.. if not, I will separate its hubs in between two Pis. He has been replaced by 'white'.
All easy mode miners are mining on three pis with 24 to 27 gridseeds each.
I just got some more Pis in today, so I will try separating the trouble rig into two rigs to see if that helps any if my original plan doesn't work. My original plan consists of simply re-imaging the SD card and seeing how it works.
2nd Edit: All up and running fine now. Faulty USB hubs were at play. Those cheap ones don't work worth a crap. Luckily I got 10 more Rosewills in the mail today and replaced the hubs and wa lah. All is good again! It is odd though sometimes the cheap hubs work and sometimes they don't. It's hit or miss I guess. The rosewill hubs work awesome with Pis though.. no problems at all! Pushing 27-30 Mh in easy mode.

I really hate to be "that guy", but ..... any update on those refunds?
I know you said you'd have them out last weekend and I realize you had a really busy one with getting this setup - I can appreciate that. Just wondering if there's any date set for sending them out.
