Hack of today, wall wart mod for USA to Euro connector. When receiving a low cost piece of electronics often you find these US type flat pin connectors without a good way to connect to a European wall socket. (with round pins) Today I finally used one of the many power cables I have laying around, probably cut of an old CD player. I soldered the wires to the flat pins, added a tye rap, used some heat shrink. This only works when the PSU is universal (100-240 volts) I guess using just heat shrink is not official a good enough insulation :-) (do not try this at home), but it works just fine here.
