So ns recently acquired an old non work microwave with the will of utilizing the transformer windings as coils for a wind generator generator. Yet upon additional thinking the seemed like kind that a waste of a perfectly great step-up transformer. For this reason I decided to save it as is, and also make that a little bit much more user friendly. This project has numerous uses, consisting of things like structure a Jacob"s ladder(a.k.a looking favor a foolish scientist), an electronic igniter, a welder, a rail gun... Ok possibly not... . But anyway lol, i hope you enjoy! :)

Let"s acquire started!

DISCLAIMER: If you attempt to replicate this task please carry out so safely! This project faces dangerous quantities of electricity. The an equipment assumes all risks related to the manufacturing and usage of this project.

So anyone who has read any type of of mine betterworld2016.org knows the I favor to execute a tiny bit the explaining around how my projects work. A transformer in its simplest form consists of two coils the copper cable wound around an iron core. The main point is made up of countless layers of iron plates sandwiched together. The an initial coil, which takes electrical power indigenous the source, is dubbed the primary winding, and the 2nd coil, which provides the desired output voltage, is recognized as the secondary winding. If there are more or fewer turns in the second coil, we deserve to make the secondary current and also voltage larger or smaller sized than the major current and voltage. If the second winding has much more wraps climate the major it"s a step-up transformer, and also vice versa for a step-down transformer. For the benefits of time, i am no going to get in the detailed science that induction, electromagnetic fields, and also flux lines.


For this task you will certainly need:

Materials:

1. A microwave range transformer.

2. Some scrap lumber.

3. A 120 volt switch.

4. 12 gauge wire.

5. Two 1/2" by 2 1/2" bolts.

6. Four washers.

7. 2 lock washers.

8. Two nuts.

9. 2 wing nuts.

10. Assorted screws

11. A strength cord(I supplied some old vacuum cord)

Tools:

1. Soldering iron

2. Table-saw or skill-saw(or even a hand-saw.)

3. Wire strippers or knife

4. A drill

5. Jig saw

If you are using a microwave transformer 보다 there should be a full of five wires. There must be two from the primary winding top top the bottom, two from the middle, and one coming from the height of the an additional winding, and also a tiny ground wire linked to the main point on the very top. Us only need to worry around the bottom two and the height one. Simply go ahead and snip the two from the middle to save them out of the way. The two wires on the bottom are where you affix the power. The an initial high-voltage output line is associated to the cable on optimal of the secondary coil, the 2nd is connect to the core. Be certain to remove any sealer prior to you affix the wire to the core though. After ~ a rapid clean v an edge grinder, ns attached mine to the screw hold the transformer to the wood base.

For convenience ns wired a move to the strength cord. So currently that you have the transformer wired that"s yes, really all there is come the electrical part. Currently on come the housing!

I used 1/2" chip board to build the real estate box. There is really not a lot come say around it lol. Because that ease of usage I fastened the 2 high-voltage output lines to two terminals made v the 1/2" bolts. That way I have the right to easily affix whatever I require to. It"s as much as you to develop or layout the housing however you want.


I would strongly recommend including a cooling fan of some kind! for my purposes, ns won"t need to have this running for much more than a second at a time so i left it out. Yet if girlfriend are building one of this for prolonged use, definitely add a fan. Transformers can gain quite warm!

Gongrats, you have successfully constructed yourself a multi objective high-voltage generator. This should produce anywhere native 2,000 come 3,000 volts, relying on the version of the microwave! This was a quick and also easy project, and I really took pleasure in making it. If you have the right to think of any other crazy and creative uses for this contraption please leaving a comment under below! i hope you enjoyed this instructable and I"ll see you following time!
