Static Sensing Biz Card

Concept of a business card that can show if stray static voltage is present. Trying to bring down unknown polarity voltage to 5V.

Trying to get 8-16kV of ESD through some passive components without burning them up. Ultimately to power an LED for a little longer than the static is present. Last ditch effort will be to scrap the LED and passives and wire up the contact points to a neon lamp. Wish me luck!

    Review schematic

    I included the schematic in with the images. It was the 2nd entry. If you wish to see how to build this project, there is also a video link on the main page. Ultimately, you only need a neon bulb and a business card sized PCB with exposed traces to get this working. Please message if you would like more details. Otherwise, enjoy the content linked throughout this page.

I was fairly certain that this would not work. I still wanted to try! ;)

Umm, not likely to have enough current to generate visible light.  You will probably need a small battery and high-impedance amplification for this to work.
