Mini Build - Capacitor Outside Foil Sniffer

A simple circuit I designed that I later adapted to support the Arduino build that identifies the outside foil or shield of a capacitor for those that don't have an oscilloscope or other means.
Please reference the new/improved Arduino design that uses two LEDs to identify the outside foil or shield of the capacitor at: • Capacitor Outside Foil...
You can download the schematic, BOM & sketch at:
drive.google.c...
Just look for the folder: Capacitor Outside Foil Sniffer w/ Arduino Version 2.0
If you missed Capacitor Outside Foil Sniffer w/ Arduino Version 1.0: • Capacitor Outside Foil...
Some other similar circuits I've designed and built in the past:

A very simple solution to something few realize makes a difference. Well done Don !!

Thank you Ron. It’s time to get back on the Airline 62-316. Thanks again. Best, Don

I built this today, works surprising well for such a simple design. Thanks for sharing.

[@RestoreOldRadios]

Jim, glad to hear it worked for you as well. Thanks for reaching out and sharing your experience. All the best. Don

Thanks for making this video and the instruction. I think I left this comment on one of the other videos, but it was probably more pertinent to this one. I wonder if somebody makes one of these premade for sale or may be a kit -thanks again.

I’m not sure if these units are still available, but you might find it helpful at: ruclips.net/video/mx1Z_zyDhw4/видео.html Best, Don

Interesting but if you wanted it to work the way u said you would have to switch read change the connections on the outside terminals of the switch . the connections in the switch are opposite the side . if you switch to the left the connection is on the right

Alex - thanks for reaching out. With this design being different, the direction of the switch provides the lowest AC voltage based on the configuration I shared and demonstrated. I confirmed this by testing ~50 capacitors I had already identified the foil/shield side. Thanks again for reaching out and watching. Best, Don

[@alexkay1874]

@@RestoreOldRadios Ok so looking at it from the top and you flick the switch to the right or red side the connection in the switch is to the negative terminal making that the foil side

[@RestoreOldRadios]

The direction of the switch that provides the lowest AC voltage points to the foil/shield side. Best, Don

Very nice! Can you make it more simple? Haha!

[@RestoreOldRadios]

I’m working on a simple solution now. LOL On a serious note, thanks for watching. Best, Don
