I am relatively new to electronics, not dealt with digital circuitry so far, but eager to learn while building my own receiver, ESC's and transmitter for a rather complex project. The receiver I had very little trouble finding schematics for - a good looking ESC was even easier. But so far I have not seen any transmitter diagrams on the web. I would like a good four channel (at least) PWM transmitter (as this is the modulation the reciever and ESC's use), which is not powered by a programmable microprocessor. Any ideas, other than buying one (for money I could spend on steel)?
