Step 1: Parts and Tools
These all need to be matched. For instance, I needed 50cm of EL wire for each shoe and the inverter I used needed to be able to work with this length. If the inverter is not powerful enough, the wire will be dim. Too powerful and it will damage the wire. Where you get your inverter from should be able to tell you the lengths it is rated for. The battery also needs to be the right voltage for the inverter.
Bits and Pieces:
- Battery Charger (for charging the batteries if using LiPO batteries) http://www.adafruit.com/products/259
- Fishing Line
- Sticky-Back Velcro
- Inverter (converts the low DC voltage from the battery to high AC voltage for the EL wire) http://www.elec2go.com.au/prod38.htm
- LiPO Battery or CR2023 CMOS battery (http://littlebirdelectronics.com/products/polymer-lithium-ion-battery-110mah)
- Extra Wire
- Heat Shrink Tubes
- EL Wire
- Wide Elastic (not pictured)
- Soldering Iron
- Scissors, Screw Drivers, Pliers etc
Step 2: Prepare EL Wire
The image shows the end product.
Step 3: Attach EL Wire
Next, stitch the EL wire to the shoe with fishing line. I found I only needed to stitch it in a few places; the stiffness of the wire helped it keep its shape.
Step 4: Modify Inverter
To connect the LiPo battery to the inverter, I took it apart and soldered wires onto the inverter pcb. So that I could put the battery cover back on the inverter, I cut slots in the inverter case for the wires.
Step 5: Attach Inverter and Battery
To attach the inverter, I used sticky-back velcro. it holds the inverter really firmly and I don't think it will fall off in use. To keep all the wires and battery out of harms way, I made a patch using wide elastic and more sticky-back velcro. The sticky back velcro didn't stick to the elastic very well, so I ended up having to sew it.
