transistor oscillation producing magnetic pulses in coil with which a magnet can interact in reciprocation motion, as a Magnetic Piston; since magnet is moving it...
Transistor oscillator (TROS) consisting of two long ferrite toroids, running from 1.5V bttry with wounding on one toroid as around a bar, generating AC in...
Interesting observation of classic TROS but with real (not LED) light-bulbs. Bemf here hitting the ferrite cores with coils, causing them to light bulbs almost...
Transistor oscillator (TROS) similar to TROS - "LITZ" www.youtube.com but with two transistors and ac/ac transformer can work as an Inverted lighting 120v 40w bulb...
Just simplified previous version to one transistor only; again, the oscilation doing the job inducing current in different configurations of coils on load side. In...
here's the schematic many asking for, work as inductor as well; what was surprised me most - the higher load (amperage) the less transistors overheating;...
