My Light Diagram

This is a simple Project of 12 VDC Fluorescent Lamp Driver Circuit Diagram . A number of people have been unable to find the transformer needed for the Black Light project, so I looked around to see if I could find a fluorescent lamp driver that does not require any special components. I finally found one in Electronics Now. Here it is. It uses a normal 120 to 6V step down transformer in reverse to step 12V to about 350V to drive a lamp without the need to warm the filaments. 12 VDC Fluorescent Lamp Driver Circuit Digram Notes Q1 must be installed on a heat sink. A 240V to 10V transformer will work better then the one in the parts list.  The problem is that they are hard to find.This circuit can give a nasty (but not too dangerous) shock. Be careful around the output leads. Parts Part Total Qty.

This is the Simple 12 Vdc Battery Operated 120 Vac Power source Circuit Diagram. This simple 1 20 V: 24 V, center-tapped control transformer and four additional components can do the job. This circuit outputs a clean 200 V pk-pk square wave at 60 Hz and can supply up to 20 W. The circuit is self-starting and free-running. If Q1 is faster and has a higher gain than Q2, it will tum on first when you apply the input power and will hold Q2 off. Simple 12 Vdc Battery Operated 120 Vac Power source Circuit Diagram Load current and transformer magnetizing current then flows in the upper half of the primary winding, and auto transformer action supplies the base drive until the transformer saturates. When that action occurs, Q1 loses its base drive. As it turns off, the transformer voltages reverse, turning Q2 on and repeating the cycle. The output frequency depends on the transformer iron and input voltage, but not on the load. The frequency will generally range between 50 to 60 Hz wit...
