PAM3.1
used solid trim, black stranded wire, and hot glue to make a more solid necklace
with protruding LEDs for extra luminosity. Jen had difficulty working with the
conductive thread, but in the end it was a learning process in e-wearables.
The Creation Process (as per Jen's
description):
- I sanded down some LEDs so they
would look more interesting and have less chance of catching on one’s
clothes.
- I got the circuitry soldered and
happy by itself and made sure the connections were good before…
- …gluing the two sides of the circuit
to the trim, which was an adventure in itself! The hot glue was occasionally
enough to melt the solder, so I had to keep away from the LEDs whenever
possible.
- I sewed the zipper connections by
hand, moving the middle “no light” state up towards red because there was
space at the very bottom of the zipper, below the green switch, for being in
an off/non-power-drawing state. I sewed big loops toward the outside of the
zipper for the wire to hook onto.
- Carefully, I looped the side
circuits into the loops and glued up the rest, leaving ample wire for the
connections to the batteries.
- I taped two small button cell
batteries (that I happened to have a pre-existing supply of) for each side,
and then picked up some crimp connectors from RadioShack to make the
connections onto the batteries. Then, a few loops of magnetic tape made the
package compact and fairly easy to take apart for battery switch-ups.
- I looped some wire through the
zipper pull and wound magnetic tape around it for a stylish, larger pull. In
testing the zipper on the circuit, it seemed that a big pull was most
comfort and afforded the least zipping resistance.
Pros
- LEDs are not obscured by anything
for higher visibility
- More LEDs increase the odds of being
visible despite hairstyle or clothing attire differences
- Circuitry is contained and concealed
within the solid trim
- Same zipper circuitry for intuitive
motion
Cons
- Difficult to repair because the trim
is glued together - everything is totally concealed after the hot glue
- Sewing the zipper was difficult
until Mouna hooked us up with better conductive thread
- The zipper is a little stiff at
first - it needs a bunch of runs to smooth out
