High voltage & marx generator
I'm looking at some instructables, and the simplicity of the cockroft-walton generator is quite interesting.
Because I've always been fascinated by lightning and electric sparks (ever since I saw a wimshurst machine as a kid), I was thinking of building a CW generator, to power a small marx generator.
Now, I found the parts, but I don't know much about electronics, so I have a few questions, and I was hoping someone here could help me out.
1) For ceramic capacitors, some are labeled for instance '15kV', while others are '15VDC'. I assume the latter only work for DC input, is this correct?
2) If I were to make a CW generator using a few 400V capacitors and a fuse (assuming I don't f*k up putting it together) like this: https://www.instructables.com/id/High-Voltage-Power-Supply-For-Marx-Generator/?&sort=ACTIVE&l
Is there a risk of blowing a fuse in the house, or is that fuse in the setup enough protection?
3) Is there any risk for other electrical devices, like a computer, when I plug this in?
4) I work at a computer repair shop, are there any useful components in power supplies, old screens...?
Thanks in advance!
