Making Flat Multicolor 3D Prints

Prints Charming walks viewers through how they make these flat stained glass inspired 3D prints of Pokémon in this YouTube video:

If you’ve ever wanted to create detailed 3D prints with lots of colors but felt limited by the number of filament slots or toolheads available on your printer, I’ll walk you through the process I use to bring these designs to life. I’ll cover how I prepare the artwork, set up the colors, get the file ready for printing, and turn a digital image into a finished stained-glass-style 3D print.

Cheers to Prints CHarming for sharing their technique!

Check out these stained glass inspired builds in the Adafruit Learning System:

Matrix Portal Stained Glass with WLED

Make a glowing stained glass window with over 2000 LEDs that animate and glow in hundreds of different patterns and colors, all without writing a line of code. The magic lies with WLED, a free, open-source LED animation program that runs over WiFi. Control your LED matrix with your smart phone or web browser, and watch your creation dance.

Driving 512 LEDs from a Nintendo Switch: ESP32, WS2812, and a 240fps

Brewser is a homebrew web runtime for modded Switch consoles. The app Matrix Studio lets you drive an LED Matrix from your Switch!

Matrix Studio is a pixel art and animation app running in Brewser, a homebrew web runtime and app platform for modded Nintendo Switch consoles. It streams frames live to a 512-LED WS2812 matrix through an ESP32 over USB serial.

How it works: frames are delta-encoded with a full keyframe every half second. A write that runs long skips the next frame instead of queuing it, so latency never builds up. Clocking out 512 WS2812 LEDs takes about 15 ms, which sets a hard ceiling of roughly 65 fps.

Thanks for sharing!

Wooden NeoPixel Xmas Tree

It’s never a bad time to make a NeoPixel project, but the holiday season certainly does lend itself to creating large-scale, blinky, colorful displays. In this project, we’re taking the classic Christmas tree shape, cutting it out of wood and mounting some NeoPixels in the tree to create a festive yuletide light display.

Happy National Video Games Day 2026

image of Magnavox Odyssey via Wikipedia

 

September 12th is National Video Games Day!!  Released 54 years ago in 1972 the Magnavox Odyssey was the first commercial home video game console. And while there seem to bet a few different days claiming to be “video game day” we celebrate today for Magnavox. We remain agnostic on which is the official day and are happy to celebrate video games any day.

Learn more from Wikipedia:

The hardware was designed by a small team led by Ralph H. Baer at Sanders Associates, while Magnavox completed development and released it in the United States in September 1972 and overseas the following year. The Odyssey consists of a white, black, and brown box that connects to a television set, and two rectangular controllers attached by wires. It is capable of displaying three square dots and one line of varying height on the screen in monochrome black and white, with differing behavior for the dots depending on the game played.
