My office is littered with little flying IR helicopters and airplanes. While these are fun, sometimes they can get a little annoying.
I'd like to build a small "no fly zone".
I plan on modifying this kit to pulse out at regular intervals 360 degrees to disrupt these infernal flying contraptions. I think it'll be really fun to watch a group of engineers try to figure out why their toys are dropping from the sky!
I figure that I'll need to reprogram the microcontroller with codes for these types of things. Also, I plan on adding more IR LEDs to cover 360 degrees. This brings up a couple of questions.
Can I run multiple LED off one pin of the controller? I noticed from the schematic, there are two LEDs off one pin. Can do more than that as long as I have transistors in place to drive the LEDs?
How difficult would it be to add a switch to change this devices mode? Meaning switch between nuking these helicopters and say TV's?
Other uses for the TV-B-Gone kit?

You can add more LEDs, I'm currently running 6 off one pin (with six transistors that is).
However, my personal recommendation would be using a 555 timer. That way, you could use a potentiometer to control the output frequency, easier that way:

Oh Shiny! Thanks for the links! I'll be looking into making that jammer as well.magician13134 wrote:You can add more LEDs, I'm currently running 6 off one pin (with six transistors that is).

I've been playing and reading a good portion of the day but I can't follow that schematic. Am I just being a n00b or what?magician13134 wrote:You can add more LEDs, I'm currently running 6 off one pin (with six transistors that is).
