DIY Ambilight – part 3

18-03-2019 - DIY

Finally the new LED strip arrived so now I had al the pieces to connect everything together.

I started by cutting the LED strip to the desired length. I had a total of 96 LEDs so I cut it in pieces of 8, 21, 38, 21, and 8 LEDs. In Hyperion it looked like this:

The next step was to put the strips on the back of the TV and solder them together again. Note: check for the arrow on every section so it points in the same direction. It doesn’t matter if its clockwise or counter clockwise because you can change this in Hyperion.

Now connect all the other pieces. Is used a 4-port USB hub to power the PI and the HDMI splitter and converter. The hub is connected to a USB port of the TV.

Unfortunately the video grabber I used didn’t work. When I tried to take a grabber screenshot I got an error: VIDIOC_S_STD ERROR 25, Inappropriate ioctl for device. Hmm…

A quick search learned my that the chipset of the grabber wasn’t supported. So I ordered another grabber based on a link I found. Different chipset but the same error. This time I got a version 2 grabber and in the link they used a version 1 grabber… So I ordered a third grabber. So now I’m waiting for that to arrive… TBC
