Tesla coil

The Tesla Coil we bring with us is small, and only generates a couple hundred thousand volts of electricity and will light up a fluorescent bulb held in your hand. The Demonstration: A fluorescent light bulb held near a Tesla coil will light up and spark, even without being plugged in! Quick Physics: The Tesla coil creates an electric field that pushes electrons through the light bulb. This is the same way the lights in your house work, except in your house, the electricty comes through a wire instead of through the air. The Details: A Tesla coil is a device for making very high voltages. Voltage is a way to measure how much energy an electric charge has. Tesla coils can make voltages of more than a million volts. The small one used in the demonstration makes about 60,000 volts. Normally, such high voltages are very dangerous, but the Tesla coil makes very high frequency electricity. This means the coil turns on and off very quickly so the electricity flows on the outside of your skin instead of through your body. The Tesla coil is very different from the Van de Graaff generator. A Van de Graaff generator makes static electricity; the charges don’t move on their own. A Tesla coil makes current electricity; the charges are flowing. One end of the Tesla coil is connected to the ground. Because the coil makes very high voltages, the electricity can leave the Tesla coil and go through the air to get back to the ground. If a fluorescent light bulb is held near the coil, the ele...

At ArcAttack, we’ve been experimenting with controlling our Tesla coils with music for years. We’ve put everything we’ve learned into the Thundermouse. This knowledge is why it’s the most advanced kit available today. Our DIY Tesla coil kit will allow anybody to create a stunning lightning display just like ArcAttack. The Thundermouse offers advanced features while limiting the design to all through-hole components. For that reason, it’s easy to assembly. This simplicity is achieved using a Cypress Psoc5 development board. We also use a unique method of primary current envelope shaping. Because of this, the Thundermouse can move fluidly through many modes of modern Tesla coil operation. Thundermouse delivers its capabilities through a single plug and play USB device. It works under Linux, Mac OSX, and Windows. Plug it in, and Thundermouse connects as a virtual MIDI...

Welcome to the Tesla Coil Design, Construction and Operation Guide. I hope this guide will serve as a comprehensive step-by-step reference with easy to follow instructions. By following this guide you can build a Tesla coil capable of generating over 4' arcs of lightning. Design The guide will begin with a basic introduction to Tesla coils, how they operate and how to properly design one. This section mostly contains tedious equations and formulas used in the design process. Fortunately the use of software programs, like the Construction This section will guide you through the process of Tesla coil construction. I'll show you all the required parts and offer advice to help you avoid mistakes. Operation Finally, I'll explain how to set-up and adjust your Tesla coil for safe operation and maximum efficiency. I'll offer some troubleshooting tips to help you solve those little issues that often come up. This guide is intended for anyone with basic to advanced experience with electronics, some free time and a desire to create their own lightning. It's helpful to have some hands-on experience with electronics, but it's not necessarily required. This guide only covers traditional Tesla coils, not solid-state Tesla coils or magnifying Tesla coils. However, all types of Tesla coils share many common parts and principles of operation so this guide may still be used as a reference for other types of Tesla coils. I try to assure that all the information in this guide is correct, but r...

Besides the lightning-bolt shows they can put on, Tesla coils had very practical applications in wireless radio technology and some medical devices. 2. The power source is hooked up to the primary coil. The primary coil’s capacitor acts like a sponge and soaks up the charge. 3. Electric current builds up in the capacitor until it reaches a tipping point. The current streams out of the capacitor into the coil. Once the first capacitor is com-pletely wrung out and has no energy left, the inductor reaches its maximum charge and sends the voltage into the spark gap (basically a gap of air between two electrodes). 4. The huge voltage current flows through the spark gap into the secondary coil. The energy sloshes back and forth between the two coils. 5. The secondary coil has a top-load capacitor that concentrates all the current and can eventually shoot out lightninglike bolts. The idea is to achieve a phenomenon called resonance between the two coils. Resonance happens when the pri...
