How do you upload sketches to the Forkuino? Do you need an additional FTDI cable?
The 1/10 Pin spacing is nice to have but a 1:1 Arduino is not really awesome. Why not build (and program) the most power saving Arduino you can get on earth? There is a really nice tutorial how much what component is consuming:
"The initial outcome is that, to save power, forget about using a development board. Further savings (like reducing clock speed) would be overshadowed by the huge overhead of the voltage regulator and USB interface chip.
So from now on I'll experiment with the "bare bones" board. However it can still be programmed using the normal Arduino IDE [via USBtinyISP]"
This would be an interesting workshop with practical output.
