Vigilant readers (ha, who am I kidding) will have noticed I've been starting on some ATmega hackery, but I'd like to prototype up without needing to but an arduino (clone) card for each one. So, off to the electronics equivalent Laminated Book Of Dreams (ie, farnell) to stock up on core components.
Discussions have come up with something like the following list, but what else should be added?
* LEDs - Was going to get both a selection single and a couple of RGB ones
* pile of resistors
* capacitors - elecrolytic and ceramic
* Diodes - signal. power, zener
* Voltage regulators
* 2n7000 mosfets
* generic transistors
* couple of atmega chips, crystals etc (core componets of arduinos)
* battery holders
* reset switches
* hookup wire
* breadboard (one decent and one small)
More specific bits I also want are
* rf12 boards
* opto isolator for telemetry input
* moar jeenodes :-)
