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.
Parts:
C1 100uf 25V Electrolytic Capacitor
C2,C3 0.01uf 25V Ceramic Disc Capacitor
C4 0.01uf 1KV Ceramic Disc Capacitor
R1 1K 1/4W Resistor
R2 2.7K 1/4W Resistor
Q1 IRF510 MOSFET
U1 TLC555 Timer IC
T1 6V 300mA Transformer
LAMP 4W Fluorescent Lamp
MISC Board, Wire, Heatsink For Q1
Notes:

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.
