I just made a improvisation on my tv-b-gone since it's not always strong enough to reach the TV of your neighbor. It was a funny project to get rid of a boring sunday Wink Inspired by these:

http://www.redferret.net/?p=7413

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 transistror 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.

Here you can see the focus screws and pinheader.


Main power and focus led power switch


Front lens.


The blue led switched on.

Havn't tested the distance of it, hope to figue it out soon Laughing

thanks Smile

I'll let you know about the range. At least 15meters worked fine (with a window between tv and the gun). I wasn't able to test it at a longer distance.

You could also use a webcam to focus the beam, most webcam movies show ir light.
