12V Stroboscope 250-400V DC Circuit Diagram

12V Stroboscope 250-400V DC Circuit Diagram

The stoboscope tube needs about 250-400V DC to operate. This aerial voltage is generated application simple voltage footfall up ambit congenital from transistors Q1,Q2 and agent T1. This ambit gives out about 230V AC voltage which is again rectified with afterlight arch U1 (must accept at atomic 400V voltage rating) and stored to the capital capacitor C1.

I congenital my stroboscope from genitalia taken from old camera beam unit. This access gave me nice beam tube with reflector, activate agent and some of the capacitors (for archetype C1). Other genitalia were the one luying around. I acclimated some aberrant triac I begin in my for the triggering circuit, but any triac which can handle at atomic 1A and 400V should do the job well.
