  • E-Field Mill : 8 Steps (with Pictures) Instructables

    After disconnection of the ground a charge remains on the material even if the electric field vanishes. This charge can be measured with a voltmeter. This is very roughly the principle of measuring static electric fields. A few years ago i built a field mill according to plans and schematics i

  • 1. The following list shows roughly which materials you will need. You may change and tailor those as much as you want. Sheets of 4mm plywood timbe.2. In the first picture you can see the whole design is based on two sheets of plywood 210mm x 140mm in dimension. They are mounted above each othe.3. Now you have to electrically interconnect everything so that it works properly. Use the brass wire and solder together the following parts. The.4. Follow the schematic to place the electronic components on a piece of perfboard. I soldered pin headers to the edges of the board to connect it.5. There isn't much to say about the Software. It's written very straightforward. The application knows some commands to get configured properly. Y.6. I just told you that the working principle of this device is electrostatic induction. So how it works in detail? Lets assume for moment we would.7. After some testing, debugging and improving i installed the field mill together with my old win-xp notebook in my attic and did a test run over.8. Now as everything is (hopefully) working fine you should gather some data. I'd recommend to use a fixed place for the field mill. Otherwise the.
