Today the missing parts for finishing rev2 arrived. And it's also working. Also the blank circuit is working! Here a first image. I will take better ones soon.

The changed firmware is now also available in the bit bucket repository. So in combination with the link to the board at OSH park. Everyone with decent soldering skills can build his own. If you do that please post some pictures.

Looking at this I wonder if a version with castellated pads for the headers would make sense. You could still solder pins on the edges, but you could also just put in on your PCB directly like an SMD component. Yes, I realize there are components on the other side of the board (and that moving them all on one side is not realistic), but you could still use only short pieces of wire...

mh.. never thought about that. But there is another reason why this will getting difficult: At least in this revision I need the PCB on the edges to run traces there.

Where can I order them ? :-D

hehe every time the same question.. (just kidding).

But thee will be maybe a possibility to order them later this year. But for now the "production" of these is not fast enough. And I do only have 3 PCBs of rev2. I should make some panel and stencil for it.

until then I have some TIL311 in stock... but they get too hot :-(

By the way I did measured the power consumption today and it consumes 5
times less and is brighter. More in a new log tomorrow.
