Transformerless is not usually practical at this power level - a transformer will be cheaper and probably smaller than any safety-approvable alternative, unless you can burn off a lot of heat.=20 You could use a capacitive dropper but the cap(s) would likely be bigger and more expensive than a 12v 100mA transformer. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
