I wanted the strips to light the wall on the backside, so the light would work indirectly. I wondered if the space between the strips was not to big. At that time I found an RGB controller with much more possibilities. It could also control more led strips so I could use the 2 spare strips I had ordered. 6 per side, and 11 cm of space inbetween.
Careful measurement and drilling M3 size holes created a mounting strip with 24 bolds. See picture above.

By having about 11cm of space between the strips and only 3 cm of wire to interconnect the strips, I needed to make new connection cables. I took an old IDE cable from an old computer and I took apart the 3 cm cables and by really a lot of cutting and soldering (12 strips x 2 connectors x 4 pins = 96 wires) I finally assembled new, longer, connection cables. Next time I will order longer cables from china.

With all the cables ready, the nuts and bolds mounted on the mounting strip I could finalize the assembly and do some testing.

I did the testing with the controller that could handle only 10 strips by specification. No problem! I had it on for several minutes and the controller did not generate an amount of heat that made me worry. So I guess 12 strips would work perfectly. Nevertheless I would use a controller with much more possibilities.

The picture above is from the simple controller, which would work very well in many cases. But hey, it did not have an infrared remote control so… to difficult to use.
