Hi.
Does anyone know the schematic of a driver board ~16mm x 10mm with a LM358 I.C, a tact switch and a couple of transistors and few resistors supposed to drive a 1500mW violet, was inside a 14mm pointer tube ? No potentiometer trimmer. It is masked white, unable to follow its traces to draw its schematic.
