Caution: These are not DIY projects for beginners. High voltages are involved that can kill you. Do not attempt to build these (or any other similar high-voltage) circuits if you don't know what you're doing. This site is not a how-to guide for newbies, but rather a resource for experienced electronics hobbyists.
