High Voltage pages

Banjo effect - long film exposure of a moving streamer
Warning: some of these devices run from 12V, but nevertheless produce voltages high enough to shock and, under most conditions, may even cause severe damage to your health. So be careful.

Remember to use bleeder resistors for all high voltage (over 40V) capacitors.

Never get close to or touch any operating HV device. Use plastic or grounded operation panels.

Build or use any devices presented here entirely at your own risk.

Additionally please note that despite my best efforts the device descriptions given on this site may be flawed or information might be missing, so always think for yourself first. If anything regarding HV is unclear then _ask_ someone, to lessen chances of getting yourself killed in some mindbogglingly embarrassing way.
