Hi all,

Here is a easy and low cost fighting system for rc models. You just need a spare channel. Code is easy to modify. Thanks to J44 for the Ir part.

I've been using it on a ground target. I can reach target at 50-75m with sunlight but you need to be accaurate.

TX Digispark version:
What do you need?
1x led 5mm infrared 940nm (I use sfh 4545)
1x MMBF170 or bs170 (for powerfull led)
1x digispark
1x convex lens (I use 27 and 33mm)



It's fun and accurate.



Receiver:
1x arduino (nano, pro mini, digispark, ...)
1x IR receiver tsop 4838 (check polarity)
1x speaker

Code are available but still in test.


Need 1 tx for each player.
