Ambilight just too expensive or not cutting it for you? Same. I did it myself, and like most of my projects it involves a Raspberry Pi.
So, here’s what you’ll need to copy my setup:
- Raspberry Pi 4B
- Pimoroni Mote LED Kit
- 4K HDMI Splitter
- HDMI-to-USB 3.0 Capture Card
- Lots of USB outlets and cables, some included and some not.
I used HyperBian, which is basically Raspbian pre-flashed with Hyperion. This handy image does 90% of the work, so take a moment to appreciate how much you don’t have to do.
I’m not gonna mention the parts that are standard, like setting up Mote lights. I will go over the wiring though:
Media > Splitter > HDMI Capture Card > Pi > TV
Now the part that isn’t as it seems, which is why I’m bothering to write this. First, follow these instructions. Before copying over artnet-server.service modify it with nano, make sure the path to the script matches where it is on your installation. For me, I had to change the user folder from “osmc” to “pi”. If you try to start or enable the service you’ll probably get the following error:
Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory.
This can be easily fixed by running the following command:
sudo apt-get install libatlas-base-dev
Okay, now go to your Hyperion Dashboard. It should be localhost:8090 from your Pi. Set the Capture Input to the USB device detected (the capture card), and the LED output format to “fadecandy”. Set the number of pixels to “64”. Save the settings and everything should work! Don’t forget to configure your lighting orientation to match the placement of your lights!
