This is a simple pulse width modulator circuit connected to a car ignition coil. It produces high voltage purple arcs and its a screamer. Oh— and it also lights up a modified CFL.
Pulsweitenmodulation / Pulsbreitenmodulation mit veränderbarer Frequenz zum Regeln des Stroms. Puls-width modulation circuit with changeble frequency to control the current.
In this video I try to show how to repair a sealed leac acid battery. I got this battery from a friend, who used it in a portable Flash lighting unit and he has…
