I've thought about this for a while now...
On the low side, a tvs diode (eg if over 12v it clamps) and a fuse which should protect a user from death?
Or what about simply a very low current blow fuse on the 110/240ac .. would these methods not make a capacitor fed power supply safe?
Never built one, but i think i shall for a simple 1w led which will never be touched... question is could one be made safe?
