As I was not one of the lucky persons to win a LittleWire, and that I had all the components available, I decided to build my own version... on perf board!
Doesn't look too bad from above, but...
... below it is a little but messier: as it is not strip board, you have to "bridge" all the pads with solder to create traces:
I was able to avoid wires, except for 4 of them (2 are a consequence of the funny ISP connector pinout).
I separated the 2 capacitors to have one close to the USB connector, the other one close to the ATtiny85.
I decided to put the jumper on the same R/A header, here is why:
I found this RX2KL05/S-5
Camden/Boss enclosure to be almost the perfect size for this baby:
The enclosure is available at RadioSpares
(unfortunately no longer at Farnell
With a little cutter knife carving, it is a nice protection for this LittleWire derivative!
Needless to say, it is fully functional and once the ATtiny85 flashed with my BusPirate, it is working as expected!
Maybe this case could be used for the original LittleWire too?
