Ive been dessingen a tracer (a device that detects an airsoft bb and illuminats it)
Ive had my fair share of troubles in desinging it and perfecting it and after lots of fails and adjustments to make it work i had a working desing that worked on a breadboard bud once i converted it to a pcb its fails me and i have no clue why. The supply is a simple buck boost converter. The detection is an IR led and an phototransistor thats inputs to an comperator with reference voltage by a potentiometer voltage devider. Then that output is put into 2 diodes to bring the constant output voltage from 1.3v to 0 and then into a 555 delay of circuit. On the breadboard it al works bud when i made it on a self desinged pcb it just makes a buzzing sound and the leds stay on or start to flikker. Does anybody got a better way of doing this or knows whats wrong with it
