  1. Hi,
    Find yourself a +- 220v/12v transformer capable of handling 200ma, a 1a bridge rectifier, and a 1000mfd 25v electrolytic capasitor and a piece of veroboard. Over a switch and a fuse take the 220v to the transformer with the rectifier in serie and the cap in parrallel you should get a bit more than 12v to power your LED's. But I must warn you The mains supply of 220 volt is very lethal. If you know nothing about power electronics leave it alone and rather go and buy yourself a comercial power supply that is capable of handling the power of LED's. The current of smal led's is a couple of mA and bigger ones do not need a lot more. Enjoy!

    This solution will supply about 17V at low load! This could damage LED
