High voltage capacitor bank (more than 2kV and 10A)
Ғылым және технология
WARNING: The experiments shown in this video involve high voltages and currents. These voltages and currents can be potentially dangerous for all living things. Be sure to always take the right precautions and wear appropriate safety equipment like goggles, gloves and ear protection.
The 'Boom box' is made out of 3 disposable camera's (you can use more than 3). I used the charge circuit from one camera and the capacitors from all 3 camera's and put them in parallel. Then I added a switch between the battaries and the charge circuit, a switch on the charge circuit itself to start charging the capacitors, and a switch after the capacitors to release the charge in one go (but I cannot recommend this to anybody because the switch welds itself together and gets stuck in one position. you would have to chose an appropriate switch that can handle the power). The 'Boom box' generates more than 2kV (max voltage my multimeter could read) and around 10 amps of current (biggest fuse it could blow with the thing).

You know you could measure a higher voltage than your multimeter can show, with a voltage divider. Use, say, a 9M resistor and a 1M resistor in series. Put the voltage across the whole 10M, and measure across the 1M. You're measuring 1/10 of the voltage. Of course the principle applies in general. Probably best to use higher values, ie 10M rather than 10K, so as not to load down the voltage. Because a digital multimeter has high input impedance, this will be OK. Of course, you can experiment. For your switches welding, you can buy old-fashioned, Frankenstein-style knife switches from educational suppliers. Or make your own.

yeah I know, I probably should've done that :-).Multimeter didn't work properly anymore after doing this a few times. It now messures twice the amount of voltage (3s lipo -> 24V ???), oops. Using the knife switches would be a great idea, thanks ;-)
Wow
Someone told me about using a disposable camera to make a zapper / shocker, so I tried it. In the process of disassembly, exposing the critical bits and reassembly, I accidentally zapped myself a couple times. When it was done, I refused to test it again. DO NOT TRY THIS AT HOME. 😂😂😂😂😂
