The Magic Frame V3 is now printed and assembled. 

The 3D design has now 8 LED row per piece of 13cm. Each row has 3 LED so 24 LED per piece. Which is 32 * 3 = 96 LED for a 52cm frame. 

Here is the schematic : 

And the schematic of the Bluetooth / HID central 

I didn't had much time to solder it and build a 3D printed box. This will be for later ^^
