A long time ago I used to make my own double-sided PCBs at home using a fairly big tanning bed for exposing the PCBs. Hauling that thing around isn’t exactly convenient though, so I decided to make a small box to fulfill the same function instead.
Helping out with the design of a giant LED wall at my local hackerspace inspired me to put together something with RGB LED strips myself. After browsing the internet for some inspiration, I decided to build an Ambilight clone.
