Build a Half Wave Villard Cascade of 28 Stages. That means for 10KV in you get (in theory) 280KV out! An incredible voltage, perfect for physics experiments.
The CDV700 dosimeter variant 6B (newer) and a few mods to improve functionality: audio connector and bnc connector.
An article on various high voltage sources. Includes schematics, construction details, high resolution images and videos.
How to make a high voltage capacitor in a few steps. See a video with my 19nF/10kV capacitor, with under 1$ cost.
An attempt on building a TEA N2 Laser and an innovative idea for positioning the high voltage electrodes.
My first ZVS high voltage driver. A lot of current, and a lot of hot plasma. Includes YouTube video.
