The facelesstech blog tackles making a paracord lanyard that lights up via LEDs.
What triggered me to build this lanyard was that I found a lipo that was small and still packed a punch. This lipo actually came out of a used single use e-cig/vape. It was 350mAh 13300 in size which would power the micro led strip for 7 hours on a single charge.
My plan was to take a length of paracord and remove all the inner strands then replace them with the mircoLED strip, I thought I better add some of the stands back into the cord to add some strength back into it and take some of the strain off the LED strip.
The project uses a 3D printed case to house the battery.
