Here is a fun project, created from start to finish by Matthias Koch: In itself, this is no big deal. The generated pattern is a 16x16 expanded pixel image, and 640x480 displays are pretty basic by now - although they’re fine for presenting text-mode information and retro...

Scott Harden built his own opto-isolated laser controller and wrote a post on his blog detailing its assembly: My goal was to utilize a free hardware output line to signal to a device that I build to modulate the laser in a special way. This way there would be no modification to any...

Solid-state relays introduction from Vishay, (PDF) MOSFET SSRs feature an optocoupler construction, but have a pair of MOSFETs on the output instead of a phototransistor. A pair of source-coupled MOSFETs emulate an electromechanical relay by providing bidirectional switch capability...
