I had a need for an "IR remote control signal repeater" to enable the operation
of several pieces of A/V equipment now hidden behind the doors of some new
cabinets. The local video store would be happy to fix me up for only $250.00!
(Oh Boy!) Well, I had a couple Tiny12 chips that were ophaned by the arrival
of the newer Tiny13, and my obsessive/compulsive nature dictated that one
must be used for something. Two Avr port pins would easily drive two pairs of
IR leds, and a salvaged IR receiver module provided the data input. Sofware
timing is used to drive four salvaged leds at 36 khz when the receiver output goes
true. Total size of the assembly language program: 37 words. Total cost: $1.50.
In spite of the fact that this function could be accomplished with two transistors,
two capacitors and a couple resistors, the Avr solution still seemed more elegant
and satisfying 8-)
This little project made me wonder what other sorts of very simple, silly, overkill,
or even lame applications other "Freaks" may have come up with to *actually
solve* a real world problem, as opposed to just idle or educational tinkering.
I have attached my source code for all to use and enjoy!
