Prelim Photon Cannon Test

[fox46]

Back in 2001 I participated in a spinoff of FIRST called "Canada First" (As our FIRST had yet to come to Canada). The competition that year involved firing squash balls at targets. Lasers were prohibited so we used a 35W household halogen 12V pot light in a cardboard tube with a magnifying glass mounted inside the tube at the appropriate focal length to project a perfect "spot" on the targets. We inserted a piece of aluminum with a + slot machined in it and the result was a perfect crisp projection of a crosshairs on the targets. It worked magnificently well.

This being said, that competition, all the drivers were oriented to face the same direction and the targets were opaque so nobody was exposed to any aiming lights. I must say that if I felt it was impeding my drive team's ability to compete I would not have any bad feelings about launching a complaint against the offending device. FIRST has given you some incredible tools at your disposal (CRIO and Axis Camera). You should be endeavoring to use them and learn as much about the technology as possible.
