Hmmm. I have not considered laser diodes. I've seen some tight light cones come out of leaded parts, so I was thinking LEDs like slboat is using.

I am going to hold off saying more until my new breadboard and variable power supply get here and I test what I think. I think, if a 555 based beacon can be done cheaply then it should be posted here for anyone with the skills to make. But since SL_Boat has the contacts in place, and if it works he could sell both. But that is conditional on sooooo many levels. BTW, Using an altered Miru Mod Arduino an AR Drone will lock on to and follow a 980nm laser diode much better than the 940nm LED. I am hoping that this will follow true for the Rovio. Also, exceeding the PRV/PIV @ 1amp on a 1n4148 will melt and ignite your breadboard...

Rovio's don't like fire. In fact there was a high-school or university that used Rovio as a base for the legendary Trinity Fire Fighting Robot contest a few years back.
