Just playing Super Mario All Stars on an RGB matrix panel as you do.

To keep things together better, I 3D printed a bracket in two pieces, the subject of a work in progress playground note: https://adafruit-playground.com/u/jepler/pages/3d-printed-bracket-for-4-64x64-2mm-rgb-matrix-panels

This is using a 3rd party breakout board with 3 HUB75 connectors. I recently added the ability to drive up to 3 connectors to Adafruit Piomatter, as well as temporal dithering.

In this specific interest, I'm using 2 connectors to drive a total of 4 64x64 panels. --num-planes=6 --num-temporal-planes=2 means I'm getting effective 18 bit color, albeit with the least significant 2 bits being shown on alternate refreshes, creating a tiny amount of 44Hz color shimmer.

All these "go faster" tricks together give me about 88Hz refresh rate on the panel, despite that we're still limited to about 10MB/s of data between the PI's main CPU and the PIO peripheral that's acting as the LED controller.

@3dprinting And of course there will be LEDs for illumination, and an ESPHome (or maybe two) to monitor and control it.

I've just posted about a couple of neat I2C modules that I'm planning to use with a MIDI controller at some point.

Measuring voltage w/bad LEDs it's around 80vdc. Short around a bad LED and it drops to around 40-50vdc. The LED driver shows its output from 36-65vdc and 300mA. It would seem the driver is cranking things up to hit some level of current flow?

Good day and welcome to fun with white LED fixtures. Today we have two of them, one that’s dimly lit and another totally borked. Both can be semi-revived by shorting around a burnt out LED.
Most of these fixtures have all of the LEDs in series, which means if even one burns out the whole device quits working. Not a great design.

Yet another MIDI monitor on yet another small, neat, microcontroller - this one the Waveshare RP2040 Matrix which has a great little 5x5 programmable LED matrix onboard.

And no, I'm not bored of these things yet :)

#LEDs #prototype

Quick test with a #PixelBlaze and some DIY addressable LED paracord. Encasing the 2.7mm LED strand in the paracord took a bit of work but makes it looks nice.

First time using one of these and so far it's much nicer than some of the other things I've used. Looking forward to playing around with the accelerometer and live coding.

This is my way of showing how awesome I think KiCad is. @kicad #kicad #LEDs

Finished this art piece for my office!

The base for this piece is a cork board. I painted the frame, covered the cork in fabric, added a string of WS2812 LEDs controlled by a Pixelblaze V3 Standard LED controller, and then finished it up with some mirrors and flowers.

This art took 23 calendar days to finish, but only 7 of those are days where I actually made progress on this project. The other 16 days were focused on other events and projects in my life.

The materials cost:
$39 USD for Pixelblaze
$35 USD for the LEDs
$20 CAD for the fabric
$10 CAD for the mirrors
$ 6 CAD for the fake flowers
$15 CAD paint
$ 5 staples
+ cost of tools and miscellaneous supplies

Wore some LEDs on a call with my electronics friends yesterday. This set of LEDs is my first time working with WS2812s and second time working with a Pixelblaze. Sunday these lights will be going onto an art piece I have in the works. But maybe I should do a photoshoot with them first.

Using my barycentric coordinates to implement vertex color interpretation.

I can use the same alpha, beta, and gamma values for depth buffer calculations, so I can have good looking intersecting triangles.

If you want/need a 32x16 RGB pixel panel and some alkaline batteries, the Mc2 Pixel Purse is on discount at amazon again. $8.99 at the time of writing this. I've deconstructed several for the panels, and at this price it's worth it.

Heute kam ein Paket an, darin auch ein MOLEX Adapter. Jetzt habe ich einen #ESP32 mit einem LED-Strip, der von der PSU meines Computers mit Strom versorgt wird!
Wer braucht schon kostspieliges RGB, wenn man es auch selber bauen kann und dabei noch was über die Hardware lernt?
Ach und man kann natürlich #FOSS wie #WLED installieren und so jede Menge neue Möglichkeiten eröffnen!
