[Note: Jameco is currently offering all the parts I used in this video as a perfboard prototyping kit — just add wire & solder. ] When you think “DIY electronics,” one of the first images that likely comes to mind is of parts and wire soldered to a standard piece of perforated circuit board — […]
Repair broken tracks with wire and solder. On Upcraft.it, MAKE pal Andrew Lewis shares some tips and tricks for repairing switches. With this switch, I was able to reposition the broken corner of the board and glue it back into place with epoxy. A close examination of the copper tracks on the circuit board showed […]
Jeri experiments with Dupont Luxprint Electroluminescent inks and converts an old LCD into a simple EL display. She also demonstrates that super glue can be used as the dielectric and that zinc sulfide glow powder does not work well as an EL phosphor.

I’m glad to see Jeri is back to doing her quick n’ dirty “Short Circuit” videos, where she shoots, edits, and uploads a benchtop tutorial video in record time. Sure they’re funky, but they get their point across. In this video, she shows you how to make a simple audio direct digital synthesizer (DDS) using […]
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.
