12VDC Fluorescent Lamp Inverter

Schematic design of 12VDC Fluorescent lamp inverter
Part List :
Capacitors	Resistors
C1      =  100 μF / 25V Electrolytic C2,C3 = 0.01 μF / 25V Ceramic C4      = 0.01 μF / 1KV Ceramic Semiconductors Q1     = IRF510 MOSFET (heatsink required) U1     = TLC555	R1     =    1K Ω ¼W R2     = 2.7K Ω ¼W Others T1      = Mains transformer             (220V Primary, 6V/300mA Secondary) LAMP = 4W Fluorescent Lamp MISC = Board, Wire, Heatsink
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.
