Step 1: The Materials
2x - 3x3cm clear plastic plate (I cut them out of a haribo box)
3x - LED-stripe piece from a stripe with 120 LEDs per meter
1x - 12V DC power supply
Step 2: Tools
1.Remove the protective film from the back of the 3 LED-stripes and stick them on one of the clear plastic plates (I used the printed ones for the back).
2.Solder the strips together. Connect + with + and - with - and add a main power cable in the middle and test it out.
3.Put some hotglue onto the sides of the ground plate next to the LED-stripes and put the top plastic plate on it.
4.Stick some double-sided tape onto the back of the panels.
