A small Tesla Coil (12` range), Jacobs Ladder or a `Antigravity Project` from the book `Electronic Gadgets for the Evil Genius`, but I am having a very hard time locating part for these projects. It is a nice book but there project cost estimate is way of the mark (by a factor of 10-20 more). And the only website I have found is the website from the book and charge an arm and leg.

Were can I buy high voltage capacitors, avalanche diodes and high voltage transformers in the 10KV range and higher. Does anyone know of a good source for these parts Ebay is the best bet. For HV transformers, neon-sign transformers are generally the most available but this depends a lot on how popular neon signs are in your area, as well as in some cases regulations that restrict voltage/power, or mandate internal groundfault sensing electronics. The only widely available species of HV transformer is the microwave oven transformer, but their relatively low voltage and high current capability make them difficult and more dangerous to use. Be careful with those evil genius books. I have one and I`m not at all confident that details are explained enough particularly with HT projects working straight off the mains ! I beleive there is a website the author sells the required parts from Farnell sell control panel transformers for converting 208VAC to 600VAC down to 115VAC or 230VAC. You could run one in reverse to give 600VAC or 830VAC, depending on whether you need isolation from the mains or not. You can then use a capacitive voltage multiplier to give 10kVDC. Whether isolation from the mains increases safety is debatable. If you use an isolation transformer and want the secondary to float, you need to ensure the insulation can withstand the secondary plus the primary voltage. The transformer I linked to above is only tested...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
