Speedy2 R/C speed controller


Alrighty, this is a pretty straight forward one. [Jason] discovered our tips line – he sent in quite a bit of stuff. I scored a pair of $120+ RC cars for $25 each recently, and this would come in handy. In fact, the store drone that checked me out didn’t believe that I could build my own speed controllers cheaper than they $30 units they had on the shelf. This R/C car speed controller uses a SMD pic 16F84 accepts standard servo input from a stock controller. It uses several fets to drive a motor at up to 40 amps. Everything you need, including eagle cad files is included in the zip file.

(I’m down in San Antonio this week – so far it’s been fun. I finally picked up a panavise junior and restocked my heat shrink and soldering supplies. )
