EL Wire can be dangerous and can give you a mild shock. We have taken an extra step and added conformal epoxy coating to help prevent unintended shocks
Step 1: Materials
- 3 Strands of EL Wire
- 3V inverter (Must be 3V)
- EL Wire Driver Board
- LilyPad Arduino
- Conductive Thread
- 5 JST Cables
- LiPo Battery
Step 2: EL Driver Board
The circuit for the board is quite straightforward. The triac switches power between the JST housing/EL Wire and the inverter. When the gate of the triac is pulled, high current can flow and the EL Wire is powered.
Additionally, we have added a conformal epoxy coating on the board to help prevent unintended shocks.
Step 3: Attaching JST Cables
Start by trimming, stripping and tinning the wires of the JST cable. Line up the two black wires and solder together. Slide the heat-shrink tubing over the solder join and shrink the tube with your soldering iron. (I find it best to use are large part of the iron, not the tip, and keep the iron moving of the tube.) Repeat again with the red wires and slip the tubing over both sets of wires.
Repeat this same process for the AC output wires. (Note: for AC output it doesn't matter which wire is soldered to the black or red wire of the JST cable.)

Step 4: Sewing and Planning
For my design, I wanted 3 nested blue lighting bolts. Having chalked out the first lightning bolt, I connected the power pins (+ to + and - to -) of the LilyPad and the EL Driver. I then connected my inverter inserting the DC input line to the DC-I labeled jack and the AC output line to the AC-O jack. I then tacked down the inverter cables with some invisible thread.
