This Instructable will walk you through building a medium sized Tesla coil.
Unlike some other high voltage experiments, a Tesla coil’s streamers can be very harmful. If you are shocked by the streamers, you will not feel pain, but your circulatory and nervous system can sustain severe damage.
Gather all the materials.
Put a small slot into the top of the pipe to wrap one end of the wire around. Slowly and carefully begin to wrap the coil, making sure that you don’t overlap wires or have spaces. This step is the hardest and most tedious part, but taking a lot of time will yield a very nice coil. Every 20 or so turns, put a ring of masking tape around the coil to act as a barrier if the coil starts to unravel. Once finished, wrap a tight piece of tape around the top and bottom of the coil and spray it with 2 or 3 coats of enamel.
Align the metal stand in the center of the bottom board and drill holes for bolts to go through. attach the bolts tightly upside down. This will allow you to put a base for the primary on top of it. Then bolt the primary’s base in. Take your pipe and wind it into a pretty spiral. Then mount it on the supra-base.
The simplest way is to make a salt water capacitor, using salt water, oil and tin foil. Wrap the bottle in foil, and fill it with water. Try to get equal amounts of water in each bottle, it helps to keep the power output stable. The maximum amount of salt you can put in the water is .359mg/mL. This ends up being a lot of salt, so you can tone down the amount a lot, just make sure that you use he same amounts on salt. Now put a few mL of oil slowly into the bottle. Punch a hole in the top of the cap and put a length of wire in it. You now have one fully functioning capacitor, now make 5 more.
Bring it outside for it’s first run, as it really isn’t safe to run anything this potentially powerful indoors, there is a high risk of fire. Flip the switch and enjoy the light show. I still don’t have a NST, but I’ll add pictures of my coil.
