How to Build 12 Volt DC Fluorescent Lamp
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.

12 Volt DC Power Suplly Adaptor
This series of images you can apply to make an adapter or power suplly with the output voltage (V DC output 12V). Power supply in the only protected by a capacitor as a safety if the power supply is connected to the load on the circuit.
So I recommend using 35V capacitor with a minimum specification. The security of power supply to power the more we can menggunakkan transistor TIP, but I have not discussed it. To the diode bridge can be compiled from the 4 then you solder the diode bridge rectifier into one or you can buy a bridge rectifier so that the comb-shaped (sideways) or the box. At least I would suggest using a diode bridge 1 Ampere, in a series of adapters, the bigger the better course of ampere diode current in the circuit. Diodes like toll roads, and current as a car passing by. The larger and the width of the existing highway, the faster the flow of runs and through the circuit.
For the circuit power supply 5 V, you can change the volt regulator on the type 7805 and 7905. This application applies equally in this series. For variations such as fuse or circuit switch on / off you can try it yourself.
Transformer 18 V + - 1 A minimum CT
Minimum of 35 V + Capacitor
