Adjustable Constant Current LASER Diode/LED driver
https://www.electronics-lab.com/adjustable-constant-current-laser-diode-led-driver/
I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and should have some sort of constant […]

ESP32 Burninator is a tiny laser engraver
https://www.electronics-lab.com/esp32-burninator-is-a-tiny-laser-engraver/
As the name implies, a linear stepper is linear a variation of the rotary stepper motor design, radially cut and laid out flat. It is similar to the rotary version in operation and performance, and it typically runs as an open-loop system with the ability to provide high resolution at high speeds and accelerations. As […]
Photonic chip steers light without any moving parts
