The probe is a touch plate?
The probe is a bare wire, that I fed out the same hole as one of the two screws that hold it together. I wrap the wire under the screw head and over to the other screw and back again.
This is just a prototype- proof of concept, The production version can use some conductive rubber or maybe even conductive paint. My probe contact has 1M in series, so can be pretty high impedance.
Did you "borrow" a plastic case from a USB charger or did you 3D print one for your "plug?"
Actually that is an off the shelf replacement plug. I removed some plastic inserts from the end, but the circuit board fits entirely inside that stock plug housing.
The company I am trying to get to make these with me, has some funny plugs tooled up and in their product line.
So I could fit several of mine inside that plug housing... (or one with proper UL spacing)
I would really love to hand this off for them to finish... I did the hard part. But this still need UL approval, yadda yadda,,,
