The PIC program looks for these micro bursts.
In an electrostatic detection all that is getting detected is a voltage gradient and you don't know if it is simply an efield or an ion burst or whatever. I found that there were all kinds of different electrostatic fields in nature. For example - Lots of bushes and trees have a big electrostatic charge. So that was when I invented the PIC program to detection of ions. I used a PIC 12F675 it has a few A2D channels ideal for this sort of thing, and of course there are timers you can also use to time the ion bursts.
The PIC basically times the pulse created in the circuit and if it within the ion burst time window then it triggers pulses in the ear phones.
I don't know how to make this any clearer but if you don't understand I'll try and explain.

... I tested it with my air ion charger and a ozone generator and the ion detector immediately responds up to 10 feet away.
... So far no ionizations. Pretty much given it up. Still use the Tesoro though.  |
Hi Goldfinder,
Your circuit is very interesting.
It represents the first understandable improvement over the simple static detectors I have seen in this forum.
I have seen other signal processing circuits intended to detect ionic activity by extracting signals from narrow time intervals.
These circuits involved more complicated discrete digital circuitry to filter and process short interval signals, but they were never published here.
I suspected you would not have detected any signs of ionisation from long time buried gold with your ion detector, as you confirmed.
I am wondering how you determined the ion burst time interval to program your PIC to.
From what you posted, I am guessing you may have calibrated it to an air ion generator which produces ozone, or possibly some other source of ions?
Second, I am wondering how you originally discovered that ions will create bursts of pulses within a given time interval.
Is this something you discovered on your own, or is there a printed source you learned this from?
Best wishes,
