The parts from the prototype distributor arrived yesterday.
We assembled the first prototype in significantly shorter time, than we did on site at the MakerFaire.
Having a proper pcb makes a hell of a difference.
Thanks to jue, andy, cawi and lemoer for the efforts!

And this is the next revision, after the other members of our freifunk community complained about 'one' being to few LEDs.
Tripled the LEDs, tripled the current, by cutting the base resistors value in thirds, and reducing the corresponding pullups resistance to 4.7K.
Still purple, still taking 5V but now from a smd micro usb port instead of a tht one.
Side node: Reichelt does have exactly one micro usb port...
And thats footprint is not known to KiCad...
We aim for another usb port, in order to have it prepicked by our upcoming chinese pcb vendor. So this surely not be the last but current revision:

This is the first draft OSH Park rendered:

A few days ago we started to move our design from stripeboards to actual pcbs currently manifactured by OSH Park, as well as Aisler.
As it turns out, KiCad is intuitive enough, as I got a working prototype in the first try.
