Always wanted to build one of these and now I have!

This is a more frenetic color-demo mode, but my goodness I love it so much. The video doesn’t do the colors justice; they’re so vibrant. Sadly my phone struggles with the refresh rate of the board, but there’s no tearing in person.

Emergent behavior is just the coolest. And it’s USB-C powered!

Open source, as always.

Hardware:

• Raspberry Pi Pico
• Seengreat RGB Matrix adapter (https://www.amazon.com/dp/B0BC8Y447G)
• Waveshare RGB-Matrix-P2.5-64x64 (https://www.amazon.com/dp/B0BQYFRVTR)

Software:

• Philhower core (installation instructios) 4.5.4

The Matrix Adapter was really great; everything Just Worked with the right pinouts set and having native USBC PD rocked.
