EL Wire: make it, connect it, power it

[Jeri's] back with a series of videos that outlines the step-by-step electroluminescent wire manufacturing, making EL panels from PCBs, and assembling power supplies for EL hardware. These concepts are actually quite approachable, something we don’t expect from someone who makes their own integrated circuits at home.

The concept here is that an alternating current traveling through phosphors will excite them and produce light. You need two conductors separated by a dielectric to get the job done. For wire, [Jeri] uses one strand of enameled magnet wire and one strand of bare wire. The enamel insulates them, protecting against a short circuit.

But that’s not all, she also tests using a circuit board as an EL panel. By repurposing the ground plane as one of the conductors, and using the solder mask as the dielectric she is able to paint on a phosphor product resulting in the glowing panel.

Finally, you’ve got to get juice to the circuit and that’s where her power supply video comes into the picture. We’ve embedded all three after the break. It’s possible that this is cooler than blinking LEDs and it’s fairly inexpensive to get started. The circuitry is forgiving, as long as you don’t zap yourself with that alternating current.

Making EL wire

[Jeri Ellsworth] adds electroluminescent wire to the list of things she makes. The materials list is incredibly low. The common components are epoxy coated magnet wire for the center conductor and bare wire for the second conductor. The part you don’t have on hand is phosphors, although she does link to a source.

The bad news: she doesn’t show us the build process or share the details about the inductor that fires this thing up. The good news: in-depth videos are on the way. In the mean time you can marvel in her glowing success at the end of the video, or check out some of her other electroluminescent fun.
