This instructable will show how I built a small Wimshurst influence machine with two CDs, pieces of scrap cardboard and some tin foil. These are instructions for.

The Wimshurst machine shown below was made by me using two CDs as the disks.

Because the disks and the capacitor are small it doesn't build up a lot of charge, resulting in a small spark. You can see a video below of how to make it step-by-step.

Part 1 – Overview, Materials, and Tools

Being hand cranked. The parts of a Wimshurst machine and a bit about how it works A Wimshurst machine has two disks see the diagrams below , each with metal sectors or segments on their outer faces. The disks turn in opposite directions. The hand crank is connected directly to two big pulleys near the bottom. Belts then extend from these big pulleys up to small pulleys attached to each disk.

However, one of the belts is twisted, like the number 8, causing that disk to turn in the opposite direction of the other disk, whose belt is not twisted. Wimshurst machine parts from the front. If for example a positive charge is brought near a conductor, it can be seen that this conductor is polarized.

And of course charge x vector is a dipole moment. Check out the channel of this youtuber Thomas Kim.

He has all sorts of interesting electrostatic machines made from PET bottles and CDs, he doesn't provide much information, they are probably intended as demonstrations. He also has a CD wimshurst machine. I did get the Idea of using aluminium tape for the second pair of disks from him.

Small Wimshurst Generator From Cardboard and CDs

A Wimshurst machine and all other electrostatic influence machines are nothing more than elegant, mechanized versions of a sort of double electrophorus. A Wimshurst machine consists out of two parallel, counter rotating discs with metal strips. The strips pass under so called 'neutralizer' rod which do the separating out of the charges on the strips and the strips also pass under combs which harvest the accumulated charge on the strips.

The machine I have built is the mirror image of the one explained in that link, so I will give a brief, parallel English explanation. One can see in the main pictures of this step, that there are 6 different zones on the discs.

Because just touching or handling the disks is enough to charge them a minuscule amount. This charge will amplify itself as the discs are spinning. Secondly, the front disk strips on the other bottom side now have a net negative charge.

In zone 4, the back disk gets in contact with the back neutralizer rod. And the negative charge on the back is produced in exactly the same way as in zone 2.

The positive charge repels the positive charge or attracts negative charge since it's mainly negative charges that move on the other side of the disk. As the back disc moves towards zone 4. As both strips on both disks have the same charge, they repel each other.

Secondly the comb acts like a Faraday cage so the charges on the strips desperately want to escape outwards toward the comb. And this is what happens. The comb does not need a physical contact with the strips as it has conducting points and electric fields towards points are always very strong, so there the air will break down a bit and the resulting ions provide a path for the charge on the strips to escape towards the low potential of the combs.

When running a Wimhurst machine, this is visible with a small purple line from one of the points to the disks. Wikipedia has an interesting animated gif that shows everything said previously in an animation, but it is a bit complicated to deduce how everything works from it and the compact explanation with it.

In theory, the metal strips are not really necessary and this should be possible with only some charge on the surfaces of the disk.

A Wimshurst machine without metal strips on the disks is called a Bonetti Machine.A Wimshurst machine around Introduction: Electrostatic machines have always seemed a little like magic to me. Once enough charge has built up on both sides of the spark gap to break down the air in that gap, a spark occurs.

Step 2: Materials and Tools

And the negative charge on the back is produced in exactly the same way as in zone 2. Materials: Figure 2 wimshurst-materials-blue-bg. In , August J. Video - How a Wimshurst machine works Here's a very detailed video on how the Wimshurst machine works. Mascart, A.
