Next up in our Design Space series we visited interface designer George Arriola at the San Francisco Sony Ericsson office. George was kind enough to draw back the curtain and permit a peek into one of the most secretive and innovative telecommunication industries — mobile phones. Come take a look with us. No NDA required!
Jan Lategahn (Germany) has put together a series of articles and links describing simple ways to calibrate amateur electronic instruments with a fair degree of accuracy without having to spend a bundle on a professional calibration lab. Methods and devices include DC and AC voltages, resistance, current, RF level, and frequency. Above are Jan’s homemade […]
Those who follow Jeri’s mad-scientist-like curiosity and sci-tech explorations in her many YouTube vids know that she’s recently been hot to create electroluminescence. In this vid, she tries to make her own phoshor. It didn’t quite work out, but she explains the process and then shows something cool that she did discover, triboluminescence, the optical […]
[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 […]
