Hi guys,

I'm building some sort of wood case to arduino mega with LCD, keypad, LED's ...

I also want to build a 9V power supply and I found this circuit on the internet:

Input 110VAC~60Hz

output 9VDC

Details:

Part
Total Qty.
Description
Substitutions
C1 1 2200uF 35V Electrolytic Capacitor
C2, C4 2 0.1uF Ceramic Disc Capacitor
C3 1 10uF 35V Electrolytic Capacitor
D1, D2 2 1N4007 Silicon Diode
BR1 1 2A 30V Bridge Rectifier
U1 1 LM7809 voltage regulator
T1 1 110VAC to 12VDC transformers (1.5A)
S1 1 SPST 2 Amp Switch
F1 1 2A 250V Fuse and Holder

I don't have experience building power supplies so do anyone see  a problem in this circuit?
