I've had this 6x6x6 L3D Cube for years. I finally decided it was time to dust if off and replace the built-in controller with a #PixelBlaze by @wizard!
Video of the 6x6x6 L3D cube, with the frosted acrylic case, driven by a #PixelBlaze by @wizard. Which do you prefer, with or without the case? (See previous post in this thread).
Someone asked for a Fibonacci LED PCB even smaller than the 1" (25.4mm) Fibonacci128. I pointed out the problem of where to put the microprocessor & battery, they pointed out the 14mm TinyLily. So now I've crammed 55 x 1mm² XingLight WS2812 onto a 14mm PCB, ordering prototypes soon. 😅 https://tinycircuits.com/products/tinylily-mini-processor
I know, there's like nothing to the TinyLily except an M328P and a couple of caps that I could put directly on the back of the LED PCB, but I still like keeping them on separate PCBs. 🤷♂️
Yes, I think this just might work. There might be just enough room to solder the two PCBs together, using tiny castellated holes on the edge of the LED PCB. I think it'd require removing and desoldering the programming header pins from the TinyLily, or at least trimming them very flush. Could cut/sand the castellated holes through the TinyLily PCB if you actually wanted to try using tiny screws on the edge to mount this to something.
The TinyLily boards arrived and they are as tiny as advertised! I hooked one up to one of my 1 inch (25.4mm) Fibonacci128 boards to test it out and everything works! I'm ready for the 14mm Fibonacci48 prototypes to arrive. Current draw at ~6% brightness (still plenty bright) is about 50mA. Testing for an hour used about 60mAh. That's with the TinyLily programmer hooked up (3.3V regulator, FTDI chip, etc). Should be much lower with just 48 LEDs and no programmer.
This just got re-shared by @benhencke in a chat about working for "exposure". One of my favorite quotes, I believe from @Blenster: "Exposure is something you die of, not something you work for."
I received this brilliant LED triple helix, a gift from @graemegets! 🤩 This was from a gift exchange with a small group of maker friends. It came with 450 2mm LEDs on three thin strips, driven with a #PixelBlaze by @wizard. More details 🧵👇 #MakerGiftExchange
@graemegets@wizard Of course I immediately cracked it open and added a sensor expander to the #PixelBlaze. I also set out to get it fully mapped in 3D. The combination allows for motion-sensitive patterns like this. Later I hope to make this more granular than just up or down, with a smooth particle physics simulation. ⏳
I'm excited to finally meet in person many people that I admire, but the lack of diversity in speakers at my first @hackaday#SuperCon is so disappointing. It's an issue that has been brought up with leadership, but they seem to not care or want to actively address. https://mstdn.social/@alpenglow/111336992627871700
