MAKE: Blog: TV-B-Gone Gun

TV-B-Gone Gun

Ferry, from the HackedGadgets Forum, writes:

"I took 30 IR LEDs and wired them up, a SMD FET switches them on and off and is wired up with a pinheader connector to the TV-B-Gone. Internally the FET is connected to the output pin of the controller, which is also connected to the transistor driving the normal IR LED.

I took a lens out of a old beamer, and used a PVC tube to fit all the stuff in.
After all I painted it black, paint doesn't hold too well on PVC but whatever.
It's possible to focus the beam by turning on a blue LED and slide the LEDs when loosening the screws on the side."

its only been tested at about 50 feet, but im sure with that many LEDs, it can go much further...

Where I live if you pulled that out to turn some TV's off you'd get shot or put in jail or maybe both.

Why bother with trying to turn a TV off that's _that_ far away? Is it really bothering you that much? Does doing this make some really significant statement to society? Or are you just trying to be an annoying **** and remove yourself from the situation just far enough to face the consequences for your actions?

"paint doesn't hold too well on PVC"

Try Krylon Fusion directly or as a primer for another paint.
