How to make a battery powered tesla coil?
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 diificult, but it is not. It is $2.00 worth of parts and can be assembeled 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.
I answer a lot of tesla coil and Nikola Tesla questions, so you might want to browse thru my profile for more info.

Does anyone know if there are battery powered heated water bowls?
We have an outside cat who lives in the shed and I am worried his water will freeze. The thing is we have no outlets so it needs to be battery powered. thanks for the help!
I know of electric water bowls, im not sure about battery powered though.
You should try calling your local pet stores, or go online to see before you waste a trip somewhere.
Good Luck!
I think its so awesome you care so much about your outside kitty, alot of ppl would not think of that!!
