Coherent Visible Laser Module Driver PUBLIC

This is an adjustable voltage regulator for a Coherent Visible Laser Module. I've put a 1.2 k resistor across a 10 turn pot and this, together with my resistor choices should provide a maximum voltage...

Test: LM 317 voltage regulator PUBLIC

CL’s LM317 adjustable regulator seems to be bad - but is it? How to find “realistic” values for R_O and R_ADJ? Also see @signality’s LM317 test cct 01.

Bicycle-Electric 12V/5V for hub-dynamo PUBLIC

This is a little project for a bicycle electric with LED Lights. The used lamp is an AXA Luxx70 which has its optimal operation point at 7.0V. Below 7.0V the lamp lights in "steady-light" mode at...
