I've been working on the FastLED project. This week I got it to support WS2816 LEDs. They're pretty nifty LEDs -- they're like WS2812, but with 16 bits per color channel instead of 8, they have much greater dynamic range. From blinding all the way down to "Is it lit at all?"

Of course, with twice as many bits, it takes twice as long to refresh them. That's why I made them work with the ObjectFLED driver today (up to 42 parallel strands from a Teensy 4).

"To understand how the DMA works, you really need to carefully study the reference manual about the USB hardware, particularly the device-mode QH and qTD structures. Reading the USB 2.0 spec and EHCI spec also helps, but to be realistic, those are very long and EHCI is quite complicated. It's the sort of learning curve you could expect to measure in years, not days or weeks."

😨😬

Okay, even I'll admit when I'm being a bit silly...

Too much time and too many MCU cycles on my hands, clearly.

I am designing the Birthday Tower's bottom enclosure. It's gotten really crowded in here. I spent most of yesterday just trying to figure out how to make everything fit.

From the left:
- barrel jack
- audio amp
- speaker
- two Wago connectors
- Teensy audio board with Teensy 4.0 on top (not pictured)
- level shifter board
- JST SL jack

Component positions are approximate. The case dimensions are accurate for now.
