And, for those of you who want to make a Tesla Coil - Make sure that you build a set of these or buy some pre-made; the radio frequency feedback going back into your mains circuit can snake around your house and destroy your valuable devices, like your new computer or your flat-screen T.V. or your digital camera...
...or worse...you could even destroy your transformer.
This RF frequency choke works, I believe, by allowing the electric current to pass while inducing a magnetic field in the choke (filter). This magnetic field causes the RF to dissipate as it is surpassed by the 60Hz (America) electricity.
Step 1: Supplies and Tools Needed
- About ten (maybe twenty) feet of copper magnet wire from 20AWG to 26AWG
- Two ballpoint pens (the kind with removable ends and a straight, hollow center.)
- A drill and the smallest drill bit you can find that will make a hole your wire can fit through.
(I had already made one, so I only had one pen for the picture)
Also; it may be wise to make sure that your drill's battery isn't dead. Good incentive is the fact that mine was and it took me about 20 minutes to wind my second filter.
A drill isn't neccessary, but it makes the job around thirty times easier and faster.
