Chinese Plug-In Mosquito (and Human) Zapper

Another deadly dangerous insect (and people) killing device is here. Test, teardown and schematic of a cheap Chinese plug-in fly zapper (mosquito killer) from Ebay for just $1.60 including shipping. You can very easily touch the high voltage grid. The protective bars have very big gaps and they are very soft The protective cover comes off almost instantly. This can zap you even when unplugged, because the capacitors have no discharging resistors. There's also no fuse. The capacitors rated for 400V run at 620V. The LEDs should be ultraviolet (UV), but they are blue. I'm not sure this is going to attract any insect. But at least, it didn't blow up :).
