“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.”
