Building a 360 LED screen

Needed material.

• A raspberryPi 3 or 3+ with adequate 2.5A or 3A power supply
• Adafruit raspberryPi LED Bonnet (adafruit link)
• 6x of 64x64 LED panels (aliexpress link)
• Entire 3D printed structure (onshape link)
• 24x M3x10 socket button hex screws (amazon link)
• A raspberryPI camera
• A longer ribbon for the camera (aliexpress link)

Software.

I will make an .img file with a working version of the PI. The OS is (as usual) arch-linux. The libraries used to drive the LED are:

• hzeller/rpi-rgb-led-matrix
• BNNorman/rpi-rgb-led-matrix-animator

The former is used to control the LED displays. The latter is used to to send multi-layered visual information.

Assembly.

• Download and burn the PI image with the custo software (link)
• Mount the 6 panels in a structure using the hex screws and the 3D printed parts.
• If using 64x64 LED panels, the bonnet must first be modified to properly drive this configuration by soldiering a jumper on the back (see figure below).
• Connect the bonnet to the PI and connect all the cables
