Data transmition using lasers?

[chrisshortys]

ok that sounds like a pritty good idea and somthing i hadnt even considered!

So just a simple 555 timer switching a transistor to the laser with the pic at the reciever with a rang of if signal is 190-210 then target is hit by laser 01 etc?

any chance of seeing a rough circuit diagram of the way that you did it?

cheers! chris

I am using a PIC running at 3 volts and a logic level Mosfet (NPN) to the laser. A 555 would also work but for me it is easier to program the pulse I want. Sorry, I can not find a drawing.

This thead has the drawing for the target.

Thanks again!
I shall try my best to have a play with this over the next few weeks.... Ive got my college project to work on first though!
