Look carefully at the center of this picture and you'll see a Butterfly desperately hanging by it's feet from a battery charger test fixture. The thing behind the Butterfly is a HiPot which gives 1500V for one of the tests. The fan is because I'm using 300 watts of resistors for a 900 watt load; and the blue beer cans are actually 100V 47,000uF capacitors and they could fry a chicken!

The Butterfly controls 12 relays and measures .014mA current and 66V.
So anyone care to say the Butterfly is a toy?
