With the purpose out of the way, it’s time start building.

It’s all a big hack, and since I didn’t plan the board layout, it all ended up being hard to hookup to a JeeNode, so I had to tack on a Proto Board:

Those solar cells are tiny! – if they don’t work, I’ll switch to more conventional bigger ones.

I used a JeeNode USB (about 60 µA consumption in power-down, due to the extra FTDI chip), but am powering it all via a 3x AA battery pack to get full autonomy. The idea is to place this thing indoor, facing south through a window:

Tomorrow, the code…
