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, ...

The design for the MicroSlice laser cutter and engraver has been developed as an entrant into the 2013 Radioshack Microcontroller Contest which went on to win the competition.

Laser diode driver ICs Ricoh has added two Laser Diode Driver ICs targeted for laser scanning type automotive and consumer projector applications. The RN5C750 and RN5C752 are four-channel laser ...

Called RLD90QZW8, “original technology allows Rohm to reduce the temperature dependence of the laser wavelength to just Δ11.6nm – 0.10nm/°C”, said the company. “This makes it possible to narrow the ...
