Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit, so [ElectroBoy]’s dual voltage PSU ...

So what’s so exciting about this single-voltage linear power supply? Honestly, nothing — until you start looking at its thermally compensated current limiting circuit. This one is by ...

A 12V linear actuator consists of a motor, gearbox, actuator rod, and lead screw. When powered, the motor rotates the gearbox, which drives the lead screw to extend or retract the actuator rod. This ...
