25 RGB LEDs!

Well, it's time for another update! As I explained earlier, my plan is to eventually have RGB LEDs stuck to a large piece of cloth (maybe 2.5x2.5 meters), and being able to fold these pieces of cloth for easy transportation. Since this requires a bit more work, and getting the right cloth etc., I decided to first make a smaller 5x5 LED panel. I found a magnetic board hanging on my wall and decided it looked nice and square. After doing some measurements and drawing crosses, I placed my small LED circuit boards on the board. The result looked like this:

After many hours of soldering the circuit boards, stripping ribbon cables, attaching connectors, and of course a lot of tape, I got my board to look like this:

I have to agree, the tape does not make it look any prettier. Especially since the nice transparent cello tape ran out and I had to use that non-transparent type of tape half-way through. The back of the board has the LED driver boards attached, connecting nicely to the LEDs using IDC connectors:

Finally, a video of the 25 RGB LEDs working wonderfully:
