Static electricity
Archiver
Posts: 46,084
Guys I desperately need some help. I am currently trying to pursue a
static electricity project for my company. The obstacles that I face
are:
1. How can I build an efficient monitoring system to gather the info
and send it to me?
2. What kind of program would be involved in measuring charge and
how do I translate this to the BS2?

It seems on the surface that as soon as you try to measure the static
electricty, you'll ground it and will dissapate it. I think more
informaton on how it is generated would be appropriate.
I think you can get some extreely high impeadance op-amps to not
discharge it.
The op-amp may be needed as well as some high value resistors to
prevent destroying your circuits.
Pretty much any ADC chip will allow you to look at the voltage
generated from the output of the op-amp.

Put a long metallic plate along your static area and wouldn't the
capacitance change with strong static?
So, put a resistor in series with your lines going to this and you can pick
off a voltage that you could fire in to an opamp and amplify enough to stick
in to an A/D.
sound feasible?

It would probably work at 5 volts and a stamp input with some lower
sensitivity.
I tried a bit to come up with a complementary circuit that would work
as well as this one does when the new one is brought near a NEGATIVE
charge, but haven't yet.

It turns out I am also very much into Basic Stamps, and in fact have
two major exhibits at our museum running on them. One is a 6-channel
automatic AM radio station - Each channel is driven by an MP3 player
with the files stored on CF. The stamp controls the MP3 players and
the transmitter channels. We use it for "broadcasting" old time
radio programs in the museum, so that visitors hear old radio
programs and not Britney Spears or Dr. Laura when they tune the
radios.
The other is an automated exhibit (a life size diorama
of "Franklin's Laboratory") that tells the story of the early days
of electricity, and specifically Franklin's kite. The stamp operates
two MP3 Players, 6 different spot lights to illuminate the apparatus
as it is described in the audio narrative, and a couple of strobe
lights that create "lightning" during the thunder and lightning
storm. I almost forgot - the stamp also controls the sparks that
jump from the famous key to a Leyden Jar beneath it, as well as a
couple of compact Florescent tubes that are hidden inside the jar.
It is quite a show!
The site you saw (www.sparkmuseum.com) is my personal site, the URL
below is for our museum.
