Make Magnetic Generator

How do I make a battery powered Tesla coil(obviously quite small)? I've seen those mini ones as well, some smaller than a 9 volt battery. But I want to make it as large as possible while using batteries only. I built a battery powered Tesla coil myself.

One of the hardest parts of working with batteries is their life span. The primary circuit of a Tesla coil draws a LOT of current. Batteries are rated in amp-hours, meaning the number of hours they can go if the load is drawing 1 Amp of current. A good battery has about 4-6 amp hours. However, a Tesla coil absolutely has to draw more current than 1 amp in order to get anywhere near a respectable current going through the primary current (remember that the primary coil has high current, and the secondary has high voltage). So the batteries will die very quickly.

I built my coil using lantern batteries, 2 of them in series (12V), running through a pulse circuit and a car ignition coil to produce high voltage. The ignition coil will output somewhere around a 1-inch spark at a very high frequency.

The ignition coil method (which is by far, the most efficient Tesla coil you can make with a limited power supply like batteries) works very well. I have used the ignition coil Tesla coil method run plasma globes, make Kirlian photos, etc.

This is the way that it works:

An ignition coil requires a pulsed AC signal in order to continuously output a spark like a Tesla coil. Batteries are DC, so you need to find a way to pulse the DC signal. Specifically, you need to make a square wave(a square wave is where it goes on-off-on-off thousands of times per second).

There are two ways to do this:
1. Use a relay wired as and electromechanical buzzer. It sounds very difficult, but it is not. It is .00 worth of parts and can be assembled without soldering in less than 5 minutes. This way is the most similar way to the one that Tesla used.

2. Make an integrated circuit. There are a lot of people out there on the web who have used transistors to develop a complicated circuit that will pulse a 555 timer to drive an ignition coil. If you are good at soldering and circuitry, this way probably makes a nicer spark.

There is this e-book that contains step-by-step instructions on how to make a Tesla Generator. The guide is called: Tesla Secret. Since the publication of The Tesla Secret Handbook, tens of thousands of people allover the world have used it to build their own personal Tesla Generators and are now powering their homes for free!

Do you want to find out how you can also generate free electricity to power your house at no cost? If yes, then you need to download a copy of the Tesla Secret Handbook.
