A while ago I posted my $3.50 DIY TV-B-Gone Micro
, which was great and all but didn't have near enough juice. The TV-B-Gone SHP
is supposed to be able to turn of TVs from 100 meters away, but cost $50. So for about $5, I made a clone of one that seems to work pretty close to that limit. It's also very tiny compared to the commercial one.
Technically, because TV-B-Gone is a brand name, this is a "TV-B-Gone clone."
I used an ATtiny 85v as the "brains" of this, programmed with Adafruit's original code. It runs off of a 9v battery with a 5v regulator to power the microcontroller. The the LED array has 12 infrared LEDs in it, and the microcontroller is connected to a transistor that can power the whole array. The 12 LEDs blast out almost every TV on-off code, allowing you to turn pretty much any TV on or off. A 3mm green LED blinks between each code to show that it's working. When the battery is removed it is significantly smaller than the original TV-B-Gone, allowing for easy hiding.
Also, I'm entering in the microcontroller contest. If you think I'm worthy enough, give me a vote!
