Here's the black circuit board. I'll get pics of one of the red ones soon.
Bruce was one of the original makers of the circuit board pen and here is a link to what he use to sell. he always mentioned that he used to sand the back of boards but the dust was extremely hazardous to the lungs.

Those are nicely done. I have some very thin circuit boards salvaged from laptop LCDs and am still thinking about how to get them on tubes. These are thin strips, so I'm thinking I'll have to do something like you see on the Abalone blanks.

My bother is really into electronics and hie takes apart computers and things like that. He has a big bucket full of circuit boards and I want to find some use for them.
Did Bruce ever post instructions on how to make it?
I've heard soaking in acetone would soften a thin board but it never worked for me
