Isn't this similar to the currently available CircuitWriter? It's about $20.
I have a HO modeller friend who uses it to connect a resistor to the metal wheels on every rail car on his layout so his CTC signals can see occupancy. I haven't tried it myself.

That's a cool ad. If this is silver, wouldn't it get very expensive in quantities they show in the video?

Title: Company name is AgIC
Post by: Ngineer on July 22, 2016, 07:46:30 AM

It is a japanese company called AgIC. (= Silver integrated circuit)

https://agic.cc/en/

The pen is called Circuit Marker. I have no idea if and where it is available.

Caveat: "Circuit Marker draws up to 40 meters. This marker is compatible with only AgIC Circuit PET Film and Circuit Paper."

I use the CircuitWriter pen for making resistor wheels,  maybe this new product uses more of an ink?  There are cheaper sources of conductive paint but I wrote the process up here: http://cmrm.org/NewsLetters/CMRM-2016-07-July.pdf

Conductive paint/ink (silver, nickel and carbon based) have been brought up several times in the past.

There are probably more examples - I just did a quick search.
