I built this for a school project faire. It has slots for different size coils so I am not limited to one barrel. It has a custom built control box with: Power, HV in, 2 switches to control which capacitor bank to charge, and a firing switch... As you can see I also made the power supply too. I bought the metal case at fry's electronics down in burbank, CA. It has a power indicator and charge indicator LED to tell when the capacitors have reached maximum charge. It takes about 30seconds for one bank to charge. Each capacitor bank consists of 6 330VDC 120uF flash capacitors.

will somebody get this dude a silicon controlled rectifier
lol :P
i dont get it <br>
very cool. check mine i just made one
&quot;sparky&quot; can be charged with a camera circuit as long as you hook it up to a voltmeter to make sure it doesn't overcharge.
lol. same handwritting as mine. however you could have used acrylic sheets for more aesthetic view. nice control panel awsome. a better work could have been done with your coil. what type of wire did you use
the one that's on it now is 30AWG
Neat control panel! I see you use the TV connectors for power supply! lol, I do too! They work really great. <ol> <li> How many Amps are the Caps being charged with? and, by extension, how many watts are the Caps being charged with? </ol>
300Volts at 0.16amps (16ma) wich equals to 48 watts.. Its not much I know but its only 1 flash curcuit, Im actually making a new charger that can handle 500VDC at 5 amps, I also bought some giant 2400uF 500WVDC capacitors too. I will post some pics later.
0.16 amps actually equals 160 mAh.<br>500V 5A?? thats insane. do it!
yeah that was a typo, sorry about that :) And yes, 500V at 5 amps will be EPIC! I am almost done getting all the parts together...
Damn straight it will be epic! post some pics of how far the nail lodges into the 2x4 !!
LOL ok!
I don't know exactly but its less than one.. I will get my ampmeter out and test it...Along with the watts, how do I calculate that??
Watts = Voltage x Amperage<br>So if I have a line with 110 volts and 20 amps, it can deliver 2200 Watts.
ah ok I see. I will let you know later today, I have school right now :/
hah! lol. you just can't stay away from instructables and the electronic hobbyist world can you? neither can I.
nope I can't :P
Yeah! even when I do school I think of electronic stuff! lol
what is in the power supply? is it a camera flash charger?
Yes it is. Its all I had at the time.
Very cool!
Thank you!
