I'm thinking of building a Tesla Coil

AI Thread Summary
Building a small Tesla Coil can be done on a limited budget, but costs will vary based on the choice between solid state and traditional designs. Traditional Tesla Coils often utilize beer bottle caps filled with high salinity water as capacitors, while solid state designs require more components for the RF generator. Safety is a major concern, as high-voltage capacitors can be dangerous and may shatter violently. A simple spark gap can be created using bottle caps and screws, though it has a limited operational lifespan. For detailed plans and guidance, further research online is recommended.

I have a very limited budget right now. How much do you think it would cost to build a small Tesla Coil? This would include buying the components of a Tesla coil.

Solid state or traditional?
 
solid state has many more parts to make the RF generator
 
how do you make them the traditional way??

i don't have any idea how to make one but they seem to be cool.

any help?

I'm not sure. whichever is cheaper I guess
 
The traditional way is to use beer bottle caps. You take the beer bottles and fill them with high salinity water, then place them in a tub of high salinity water. It's somewhat of a crapshoot, since a defect in the glass can cause a breakdown, but that's what safety cages are for. People often use a neon sign transformer (with a ballast, shorting them can destroy them) to charge them up.

*These capacitors are very dangerous due to high voltage, low inductance, and low ESR. They may not be very big, but they'll have a heck of a peak current. They can also shatter quite violently.

Edit: For a spark gap, I used two bottle caps and two screws. You can adjust the length of the gap as well as blow air through, and it's very cheap. They'll only last about 20 minutes of operation though.

If you search around google, you may find more specific plans. In addition to getting your circuit tuned, you also have issues with the best gauge of wire to use on you secondary, the size and shape of your topload, and all sorts of crazy things.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
