Clear flexible printed circuits - first success

I'm making flexible printed circuits with my vacuum deposition machine. In this video, I show my first successful active circuit built with copper deposited onto laser printer transparency sheets. My ultimate goal is to make thin film transistors and OLEDs that are deposited onto the substrate.


  1. Fantastic work!

    There is a compound going around on EBay called "wire glue" - not sure exactly what it is, but seems to be a carbon-loaded water-based glue (I doubt it's anything "nano" like it claims). It takes a little while to dry, but sticks pretty well and is very conductive. Might be useful.

  2. Fascinating, as always.
    Would there be any merit to fabbing your thin film components (transistors, OLEDs, etc.) on one sheet and the traces on another? You could sandwich the finished circuit.

  3. I was looking at articles on e-beam technology for the creation of microprocessors, and the wikpedia article I saw said that most labs repurpose scanning electron microscopes, so i went to see if anyone had built a home SCM and found you. so I wondered have you thought about building the tools needed to build microprocessors using either e-bean or ion-beam technology?

    because if you can - I know quite a few people who would like to build their own (they currently roll their own using FPGA and sat solver based hardware compilers)


  4. Big kate, I've thought about e-beam lithography, which could be done with some modifications to my SEM. However, the whole process of making a working microprocessor is quite involved. If I did a video on e-beam lith, I would probably be making something pretty basic, like a single line.

  5. hello mr Krasnow

    i have something that i would like to talk with you.
    please email me at

    thank you for your time
