The fine folks at Adafruit don’t know of any reason why the speaker should get hot, but suggest that I go with the 5W speaker (as opposed to the 3W.)

I took a look at a light saber program from Adafruit, plus the AI-generated chase lights and tone generating programs. I gained insight in looking at the Adafruit RP2040 Propmaker Feather software, and how it differed from other Feather microcontrollers.

Some parts came in. I plan on cutting a hole in the iris on the bottom of the UFO model, and adding a speaker grill. On the inside, I plan on placing a speaker to emit an ambient UFO hum.

I've ordered a 40mm speaker for the UFO. It has to have a better bass response than what I was using.

I've also ordered a 100mAh and a 150mAh battery for the ACS mecha carrier.

Work on building models has been suspended until mid-month, as other projects have priority.

The MS Co-Pilot generated chase program wasn't perfect. There is a single NeoPixel mounted on the board called board.NEOPIXEL. There is also terminal strip on the board for connecting NeoPIxels. That connection is called board.EXTERNAL_NEOPIXELS.

Co-Pilot incorrectly used the former.

With the hardware progressing, it's time I doubled down on understanding CircuitPython. I want to light a NeoPixel ring with an Adafruit RP2040 PropMaker Feather, and I want to create the subtle sound of an alien spacecraft idling.

We sat down and brain stormed some of the design. We decided to add a mid layer to support effects hardware. An Adafruit RP 2040 Propmaker Feather, a LiPo battery, a speaker will mount to the bottom of the plate. A Neopixel ring will mount to the top and illuminate the windows and dome.

I have ideas. I'm just not sure which way to go.

The very top of the saucer has a 1-15/16 inch opening for a green dome to peek through and six "clerestory" green windows around the sides.

Green lighting seems almost mandatory, but I want more than a simple glow.
