Yo dudes.
I've done some nerding. Well, ehrm, most of the things I do is probably considered nerdy :D
Anyways, I tried to determine the frequency of the carrier wave on an old ir-remote of mine. 36KHz sounds about right. Next step is to build an ir-transmitter based on a pic controller. That way I can control e.g. my TV from my computer... :P

Awesome coolness-note: my digital oscilloscope triggered on a flank caused by the flash of the camera! :D
