I got mine finished up last night, seems to be working in thermostat mode so far, very cool. Might build another box with something besides a drill bit and razor blade I didn't get the cutouts perfect, and the sockets I ordered seemed to be setup for a thinner panel, need to order the ones you sent the past numbers on to see if they fit better. Wiring wasn't too bad but a little cramped inside. Thanks so much will, I am sure you have this down after building so many, but seeing all the work you are putting in even if the parts were free you are doing this cheap cheap cheap.
I've made several updates to The Black Box and am now offering 50 units for pre-order for those of you that expressed interest in locking one in now. If pre-ordering isn't your thing, I'll have another 200 available as soon as I'm done fulfilling the pre-orders.
