Go to Post Honestly though, having a cave would be one of the greatest places to build a robot. There's already lack of light and lots of floor space! Well, if you have a good cave sponsor, that is. - Bryce Clegg [more]

Re: What to do with big capacitors?

I've had this Cap for a while now and haven't decided what to do with it either - notice it's only 15 microFarad, but its rated at 3.5 kV. Possible PE = 1/2 * .000015 F * 3500^2 V^2 = 92 Joules. But touching this when charged when your body resistance is 50 kOhm results in up to 70 mA which is on the borderline of lethal. My only idea is to use a HeNe Laser power supply to build a charging circuit (need to research the feasibility of this) and then discharge the cap through some coiled up copper tubing wound around an Aluminum can (Can crusher). The brief max current through the tubing should be in excess of 10,000 A and will create one heck of a magnetic field. Hmmmm???
