Re: TI-H: Infrared cable adapter
And i'll bet you guys didn't know I was reading everything you said... As
for this, I'll agree that it's fairly simple to do...as is the garage door
opener. The real joy would be building a keyless entry emulator. Walk into
parking lot. Push button. Suddenly, 40 car alarms go off. Slowly, joy
creeps into your heart, and you feel slightly guilty about it, but then you
realize how much fun you're having.
