Pen expressing semiconductive polymers

Jim decides one day to fill his 4 colour pen with 4 semiconductive polymers....

He then jots down a cray...

Crazy!

so it's a method of laying semiconductor pathways using a pen? okay, why?

3 semiconductor polymers and one insulator, shirley?

If you can print circuit boards, you can certainly draw them. Can't for the life of me see why, but croissant for the Rube Goldbergedness.

Why? There are loads of applications
education... it is a little cheaper than the alternative
design... it is a little more portable than circuit board design software

Only 3 semiconductors and an insulator... To be honest I would expect to have to have several different polymers (and so more than one pen)...

Very nice. Colour them as well.

Jim? You mean Seymour.

[+] for the link.

I'm not sure you could create N-P junctions, for instance, just by drawing with different semiconductors. Don't you need the join to be precisely mated on an atomic scale? I like the idea, but I'd like you to address this before I vote.

I was about to answer [spidermother]'s question with a suggestion, but it seems better to spin this off into a new idea. I'll link and credit you.

[+] btw

You'll need an eraser too.
