Here’s a fun DIY that shows you how to make a 2400 volt can crusher!  Is that too much for crushing a can? Well, I can think of many ways to apply this for can recycling, can you? The promised and much awaited 2400 volt power supply went through its first test run. It was a little disappointing it takes 4 firings to get the can into the hourglass shape. One of the capacitors might be bad. Anyway a Microwave Oven Transformer charges six 400 volt capacitors through a 500 ohm 250 watt resistor. The idea is to electronically crush the soda can into an hourglass shape. via hackedgadgets video://www.youtube.com/watch?v=c7JJdfe2VL4
