Help!! Making A electro Static field meter,
Posted: Thu Jun 10, 2010 4:08 pm
Hello, All, i have been making a simple circit which is made to monitor electrostatic **van de graaf produces**
here is what i have done,
I Got a battery clip, Connected the red lead from the battery clip to the middle wire of the FET,
then Bent the gate wire Upwards in the air. *ride hand side wire*
then conected the remaining wire to the + long wire of the LED,
then the - wire of the LED to the Black wire of the battery clip,
Put battery in and it works bingo...
However, On a site im looking it it says this.
"On a low-humidity day and with a 1/2 meter antenna wire, its little LED-light will respond strongly when someone combs their hair at a distance of five meters or more."
The humidity reading of our test was at 58.0 - 60.07
the light should turn off. when a elctro field is around.
And the filed length from running a comb through hair, then putting the comb close to the wire is 6 cm away the LED turns off.. then 7 - 8cm it faids back on.
This is no 5 meters... Lol.
I did use a soldering iron..
Any help please.
This is for a ghost hunting project
Thanks... and btw i dont know nothing much about electronics.
