Jeri Ellsworth talks to Jon Beck at Maker Faire about silk-screening EL displays with electroluminescent ink manufactured by Dupont. Jon is from CLUE, the Columbia Laboratory for Unconventional Electronics. (How great is that name? Their logo is a question mark where the dot is the ground symbol.) The video is a little hard to hear, […]
Here’s a follow-up video to Jeri’s earlier run through of her fabrication of an NMOS (N-channel) transistor. Here, she demonstrates some of the electrical characteristics of a P-channel transistor she fabricated in her home chip lab. Surface-mount it ain’t, but hey, homemade!

In this vid, geek goddess of all things awesome, Jeri Ellsworth, details how she made her own NMOS transistors using a a kiln, rust and stain remover, Emulsitone spin on dopant, wafer she scored on eBay, and some vinyl sign-making material.

From Wired’s “This Day in Tech,” the invention of the IC, 1952: The first integrated circuit was fairly crude — it had only a transistor and other components on a slice of germanium. But it did show the potential of the IC, which continues today to get smaller and more complex. Just a few months […]
Jeff Reifman has written a charming little piece on his blog about “being raised by RadioShack:” At one point, Chuck paid me $10/hr (a fortune) to manually re-type the entire contents of private investigator Gavin De Becker’s client database. Chuck set up two Model II computers side by side and I manually moved his entire […]
Angela Sheehan runs a site of crafty creations called Soft Circuit Saturdays. She demonstrates lots of neat ways that you can combine circuits with fabrics to entertain all your senses and even protect your tongue. She will be showing her work at this Saturday’s Cambridge Mini Maker Faire from noon to 4pm just outside the Cambridge Public Library.
And you thought stamp collecting was geeky! I love this idea. These are cheap coin-collecting albums. What a fabulous teaching aid and way of organizing components so that students of electronics can see the parts families, different varieties of components, different package types, etc. The background labels are even color-coded so that component types are […]
