OPT4048 - a "tri-stimulus" light sensor 🔴🟢🔵

We were chatting in the forums with someone when the OPT4048 (https://www.digikey.com/en/products/detail/texas-instruments/OPT4048DTSR/21298553) came up. It's an interesting light sensor that does color sensing but with diodes matched to the CIE XYZ color space. This would make them particularly good for color-light tuning. We made a cute breakout for this board. Fun fact: it's 3.3V power but 5V logic friendly.

BIG BIG rainbows on "Sparkle motion" WLED driver board 🌈💡

We got our WLED-friend PCBs

https://blog.adafruit.com/2024/12/02/leftovers-layout-wled-board-revision-a-completed/

and are testing it with various LED grids. First, we tried out a 16x16 NeoPixel grid that runs on 5V. Since that worked well, we're now onto a much bigger 60 x 60 grid - that's 3,600 LEDs! These are some NeoPixel pebble

We have all sorts of LED strips for a wide range of needs. Chonky strips? We got those! Strips with alligator clips&nbsp

netting samples we're also testing at the same time; each one has 20 x 60 pixels and uses 12V power, so it's a good test of the DC pass-through for higher voltages. Since WLED has a limit of 2000 pixels per output, this demo uses the three output ports that are then 'merged' together in memory to make a single large grid. We have more to test soon: the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C, so watch for those videos as they come together. Coming soon -

Coming soon! We're designing a board for using WLED - and we want to make like the bestest board in the wholeworld. Our resident me

) working - this mode is neat because its 'text only' - you get 3-bit color text, it does that by creating a 'resolution' of 91 x 30 characters, you can only set the color and glyph. However, the monitor output is a non-buffered 1280x720, with each scanline generated 'on the fly', so you don't need any SRAM. This could be great for something like a Z-machine emulator (

Festival of Lights… A 'USB Stick' Sparkle Motion WLED driver ✨💡🔌🌟

To wrap up this year, we're doing 8 days (maybe!) of light-filled designs. We started with the Sparkle Motion Mini

mini Sparkle Motion prototype - a tiny, fully-featured WLED board ✨🔌📏💡🌈

which can drive thousands of shimmering RGB LEDs. Next, we were going through some of our NeoPixel samples today and found some "LED Christmas light kit" with star LEDs, its basically these stars

Attaching NeoPixel strips to your costume can be a struggle as the flexible PCBs can crack when bent too much. So how to add little shooting

with a little USB plug that has IR, a crummy mic, a tactile switch to cycle modes manually, and a tiny microcontroller that turns the LED selections to different patterns - kinda like this:

The idea is cute - but the implementation could be improved with a lil sparkle motion

! we made a PCB that would fit into the same plastic enclosure but with an ESP32 instead. it's got an IR receiver, ICS-43434 I2S digital microphone

gpio 0 button in the 'right' place, 5V 2A fuse, USB-serial converter for uploading/debugging, and two level-shifted outputs. We can probably get the case in quantity or have this be a 'DIY replacement' that folks can use to make their existing setups WLED/xLights friendly.
