The control system is build around the simple Arduino shield shown to the right, which uses simple 74 series logic to send TTL control signals to the laser diodes used in his rig.

It’s a laser engraver built from a DVD burner diode (translated). It turned out so well we wonder what other projects he’s forgotten to tip us off about?

The Arduino illuminates (blasts) the target using an inexpensive laser diode mounted on a servo motor. Interesting applications of applied math include computing distance based on sonic travel time, ...

120W laser diode for lidar Rohm has developed a 120W 905nm infra-red laser diode for lidar. Called RLD90QZW8, “original technology allows Rohm to reduce the temperature dependence of the laser ...
