LED matrix frame for 64x64 (2.5 mm pitch)
thingiverse
I upgraded the frame to match an LED matrix. One similar to the adafruit matrix was coupled with their matrix hat on a raspberry pi zero for this purpose. To power it, I connected seven 18650 batteries in parallel to a 5V pull-up. To control the matrix, a VL53L0X time-of-flight distance measurement sensor is used. It will instantly shut down the running script if no one is nearby to see it. As for the frame itself, I plan to install it on my front door where the spyhole or door viewer isn't used anyway. The simple cylinder from the 2nd scad fits perfectly with my door. The print was a straightforward one-piece design. I believe I printed it with 30% infill.
