Michael has a quick rundown of his generator build and how you can make one yourself. A belt passes over the pulley.

Van de graaff generator plans. A simple homemade Van de Graaff generator In this project we will build a device that can generate 12000 volts from an empty fizzy drinks can and a rubber band. The device is called a Van de Graaff generator. Science museums and research facilities have large versions that generate potentials in the hundreds of thousands of volts.
How to Make a Van De Graaff Generator. Ive built this Van De Graaff generator for a science coursework and it works pretty well considering it being built in a rush needa hit that deadline man. With it I managed to achieve a 15cm spark a happy physics teacher and full marks for my.

Eventually the Van de Graaff generator will attract dust reducing its effectiveness.
Wipe the dust off with a dry cloth to return the generator to peak ability. This project first appeared in MAKE Volume 28 page 124. Adam Wolf is a co-founder of Wayne and Layne LLC a company that makes open source hardware nerdery.

Van de Graaff Discharge For Students 6th - 12th. The choice of belt and roller materials will determine the polarity of the voltage produced. A very simple mini Van De Graff Generator can be made from household parts.
It wont make your hair stand on end but it could produce as much as 20000 Volts. The generator uses a nylon pulley at the lower end of the machine attached to an electric motor. A belt passes over the pulley.
As the pulley turns rubbing occurs. The pulley acquires positive charges while the inside surface of the rubber belt near the plastic pulley acquires an equal amount of negative charge. The outside surface of the rubber belt acquires an equal amount of positive.

The same Van de Graaff generator would work a lot better with something that was well rounded everywhere. Well rounded dome from a purchased Van de Graaff. These bad edges can be improved a bit by insulating them.
In the photo below you can see Ive coated them with epoxy. Even then doing this is no substitute for using something with only well rounded edges but its an. Here is how I built one and how you can too.
Van der Graaf Generator are an English progressive rock band formed in 1967 in Manchester by singer-songwriters Peter Hammill and Chris Judge Smith and the first act signed by Charisma RecordsThey did not experience much commercial success in the UK but became popular in Italy during the 1970s. In 2005 the band reformed and are still musically active with a line-up of Hammill organist. However the potential of the device was realized and Van De Graaff proposed a plan for a generator that could produce up to 1000000 volts.
He built his first sizeable model of the Van De Graaff generator in 1933 and since then more devices with higher maximum voltages have been produced. Van de Graaff experiments are all based on the fact that like charges repel. A Van de Graaff generator pulls electrons from the Earth moves them along a belt and stores them on the large sphere.
These electrons repel each other and try to get as far away from each other as possible spreading out on the surface of the sphere. A Van de Graaff machine is a mechanical-electric device which produces extremely high voltage at low safe levels of electric current. It also goes by the name Van de Graaff Electrostatic Generator We usually encounter these devices in high school where our physics teachers use them to raise the hair of some lucky student.
