Hi,
I'm kinda new to designing electronics circuits. I'm currently working on building a coil gun, for my end of semester presentation for my E&M class; but I'm having some trouble. I'm using five 400V 220 μF caps, and I've read that I will need a power source of about 400V to charge them fully. I'm using D batteries as the power source (currently 8, for 12V total). Is there a way to cheaply (under $20ish) to boost the batteries up to the required voltage? If I need to increase or decrease the input voltage, I can. Any help is GREATLY appreciated. Thanks for your help.
p.s. I'm actually hoping of bringing this in to a local elementary school, when I give a presentation on magnetism, on February 19th. So if there is a quick way to accomplish my need, it would be awesome!!
