@tmiller thanks! The #Pixelblaze Sensor Expansion Board by @wizard has a microphone, 3.5mm line-in jack, and a small MCU that handles sampling the input into a 32 frequency bin FFT that you can use in patterns. The javascript patterns can be written and edited live in a web app over wi-fi, hosted on the Pixelblaze's ESP32. It's brilliant in every way.

Sorry if you're tired of these, I'm having fun tweaking sound-reactive #PixelBlaze patterns. 😁

@xabean ha, I'm so glad you noticed! I spent longer than I care to admit trying to get them perfectly aligned, although I don't think my camera was perfectly "trammed" to the surface.
The two are being driven by separate but synced #Pixelblaze, but the pattern with particles emitting from the center does use RNG which is apparently not synced.

Such fun giving a seminar on #PixelBlaze to the women of Boston College's Girls Who Code chapter. @wizard your gear continues to inspire & empower. Hack on!

The LED cube's base came out okay. The Pixelblaze fits snugly, and the back panel looks better than it needs to. The printer is still printing the rest of the parts.

All glory to @jasoncoon for designing and manufacturing the LED cube. I'm just designing a new enclosure for it.

Gnarly wiring on the 10x5x5 #PixelBlaze LED cube. I really need to find time to solder this so I don’t need to constantly fix when someone moves this improperly.
