    LED's

    One option for you Tat2z, is a simple boost DC driver supplied by any big 12VDC power supply (like a PC supply). The one I use supplies a clean 32VDC, has a nice big choke and caps (in addition to the relatively clean DC from the PC supply), cost me $12 on fleabay and all I had to do to make it...
