Ok, I'm pretty bed with circuts, but I know electricity. (I have built a tesla coil and am not dead. yet...) This is not about tesla coils though.
I have been trying to find a simple circut to completely charge several large capicitors from (one or several) 1.5 or 9 volt battery(s), and then light up an LED when their "full nuff". This is more difficult than it sounds with so many "battery chargers" and other crap out there on google.
Something similar to a disposible camera circut would work.
Plus or minus the 300 volts output...
I need this circut as a power source for a solenoid. The solenoid is going to be a trigger of sorts. It needs to have enough power to give one sharp (and unfortunately, somewhat long, maybe as much as a 1/2 inch, probably more like 1/4) pull every time I press a button. I have already decided to use a relay button switch thing circut. When you press a button it triggers a relay. This will discharge the capicitors into the solenoid actuating the rod. I'll probably have to build my own solenoid, but I already have brass tubing and steel avalible. Magnet wire is also avalible. I have built crappy coil guns and as stated above tesla coils, so solenoids should not be too much of a problem.
Plans that only use parts avalible from radio shack would be nice.
I'll probably use the large 4700µF 35V Electrolytic Capacitor from radio shack.
Maybe several if the solenoid needs more power.
Let me know if you need more info, and thanks for any help.
