TRON Hoodie 2.0

July 13, 2018

v 2.0 As much fun as the 1.0 hoodie was, realized could take it up a notch by adding a  SOUND ACTIVATED POCKET INVERTER.  That way it would flash along with the beat when you wear it to a concert or on stage.  We stock a 6v and a 12v. To drive one length of EL Wire you need to use the 6V.  high-brightness-aqua-electroluminescent-el-wire-2-5-meters  + el-wire-6v-sound-activated-pocket-inverter + a 4x AA Battery Pack   Before soldering anything, it's a good idea to make sure the circuit works with alligator clips.  From Left : EL Wire adapter to sound activated inverter to 4xAA battery pack.    The dashed white lines on the inverter go to the RED lead on the battery pack.  Then...

TRON Hoodie 1.0

July 13, 2018

v 1.0 For a good sewing starter project, I decided to replicate Adafruit's Tron Hoodie.  You only need a hoodie, needle & thread,  & some EL Wire with a battery pack. No soldering involved.    Relatively straight forward, sew thread loops around the EL wire about every 3 inches. To get a nice curve along the hood, use a tighter spacing of stitch.    Good idea to measure the inner length of your hoodie first as I ended up having enough EL wire to do half the back too.  A second consideration is if you want it inside the zipper or outside.  Inside you won't see half the EL if you zip it up.  I chose a reversible hoodie, so...
