doh! yet another mistake I made I tested it with 6V, thinking its fine, and thinking that 1.2V*4=6V . . . blaaaaah. Perhaps people will have to either use a 6V RC pack, or a 9V battery to power the microcontroller with the 4 cells powering the servos . . .Writing this tutorial has been such an educational experience for me . . .For my particular circuit, that prototyping board would not have saved time as the bus is in the wrong spot
you (and everyone else) has my full permission to fully criticize my work to the fullest I only want the best and most correct info on SoR . . .
So pretty much any one of these will work? http://www.digikey.com/scripts/DkSearch/dksus.dll?Criteria?Ref=883&Site=US&Cat=33424294
Even though it's bleedin' obvious (or is it?)......What is happening with the servos with remotre control you put in on the 2nd part of the series?Are these now removed from the equation?
it wasn't 100% clear to me how the soldering on the back went, i.e which pin to which pin. You might want to edit the picture so bright lines are overlayed on the soldering so that it's clearer?

I'm lost now. Can you link to the exact one you picked?
Ok I made some changes in a few places to account for my battery mistake. I now designed it so people can take two directions: a 6V+ battery pack (easy), or 4.8V batteries with holder and 9V battery (more complicated but cheaper).

I'm willing to bet a 3 year old can understand this enough to build the circuit . . . (apologies to all 3 year olds reading this tutorial)
since im leaving this weekend for my 6 week trip i wont have time to really look into it until late April . . .
