This was build on a 2"X4" perf board from RadioShack.
All of the parts can be bought from Allied Electronics
or Jameco Electronics
. However I find Ebay very useful for quickly finding what I need any buying it for cheap. Digikey is also a good source. Heck, in a pinch even Radio Shack carries almost every part except for the LM358 and the voltage monitor. Jameco even has voltage monitor kits. They seem to be centered around the hobbyist electronics gurus. Probably the best source is Jameco.
There are many tutorials in my blog. Everything from antennas, to scratchbuild airplanes to motor construction is there and it's not clutterd with junk either. My purpose on here is to educate and be educated for the benefit of those who enjoy the RC hobby.
