[David] sent in his laser beam analyzer project. It’s a complete analysis system built from off the shelf hardware. Even if you’re not into lasers, the project combines several technologies that are useful for the hardware hacker. A laser beam is focused to shine onto a spinning reflector. Beam signal is attenuated by adjusting the distance with a stepper actuated sled. The beam is then measured using various sensors.
I thought we were due for a laser hacks category, so I created it and added some of the older laser hacks to it.
