Hi guys,

Most of you know about the TV-B-Gone, but I want to make one of my own.

Could I wire up 3V to a switch and IR LED, and would I be set? Or is it more complicated than that?

 

Much more complicated. An IR remote is a modulated signal (about 38 kHz). Different TVs use different codes. TV-B-Gone is basically a microcontroller, that store and generates these codes.

I'm building this, sort of... I re-did the PCB, so it was single-sided, and removed a few unneeded parts. Waiting on the microcontroller and resonator (UPS guy should have been here by now...). The firmware is in 'C', which I've never used, so no idea if I compiled it correctly. The PCB I made is 1"x2" (more or less...) .
