Hello!
As a school project we are going to either
1) Invent something new
or
2) Take something and develop it to something new
and I was thinking about taking a lab heatsink, putting in a cheap IR diode, put a fan on the backside of the heatsink and couple it all up to a power supply with a switch. Okay? Now what? So I'm going to put a long foam tube where the laser comes out with a cap on it on the far end, and then drill a hole somewhere in the middle of the tube, in this way, when I demonstrate it noone needs goggles as everything is hidden and what is so new is that you just stick in a match or whatever in that hole I drilled, and voila! It ignites..
Now that I think about it, it sucks. But I want to do something with lasers. What would you suggest? We have a total budget of $25 per student.
I was also thinking to do a shock-absorber which I've been thinking about for the past weeks, and I have also tried it in my R/C airplanes and no matter how I land and in what speed, force, etc. the plane never gets wrecked. But I don't want to show it to the people there, they might steal it and earn some money on it.
What do you think? What should I do?
