Don't look at me LED jar - Build guide.



This is a fairly easy project to build and only need some soldering and gluing. Video and background to this project can be found here.

Build it

Start by splitting up the led strip to eight half meter stripes and solder it together. The resistors are for reduce ringing and cross-coupled signals. 



Glue the stripes to the jar and put the beat stripe/ring inside the jar. The IKEA jar I'm using is really hard to get the glue to stick to the frosted part ended up using som sort of super glue.













The led strip can be ordered from Adafruit or aliexpress
