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 stepdown transformer in reverse to step 12V to about 350V to drive a lamp without the need to warm the filaments.
|C1||1||100uf 25V Electrolytic Capacitor|
|C2,C3||2||0.01uf 25V Ceramic Disc Capacitor|
|C4||1||0.01uf 1KV Ceramic Disc Capacitor|
|R1||1||1K 1/4W Resistor|
|R2||1||2.7K 1/4W Resistor|
|U1||1||TLC555 Timer IC|
|T1||1||6V 300mA Transformer|
|LAMP||1||4W Fluorescent Lamp|
|MISC||1||Board, Wire, Heatsink For Q1|
1. Q1 must be installed on a heat sink.
2. A 240V to 10V transformer will work better then the one in the parts list. The problem is that they are hard to find.
3. This circuit can give a nasty (but not too dangerous) shock. Be careful around the output leads.
