Swadge 2019

Super Magfest is a four day-long event dedicated to the appreciation of video game music, gaming of all types, and the gaming community.
The Swadge, short for swag badge, is a circuit board badge which staff (red boards) and supporters (black boards) were given, and everyone else could buy at Super Magfest (blue boards). The official product page is over this way.
The 2019 Swadge has six modes:

• Colorchord, music reactive LEDs
• Reflector, a head-to-head reflex game
• Six Sided Die Roller
• LED Animations, unlocked by winning at Reflector
• Flashlight and strobe
• Instrument tuner

For the 2019 Swadge, I was the lead firmware developer. I wrote the mode framework, Reflector, D6, the LED Animation framework, and Flashlight. I also coordinated the other contributions. CNLohr wrote Colorchord, adangert designed the LED animations, and thaeli wrote the tuner.
The entire project is open source, and you can find it at GitHub below:

We manufactured 2700 Swadges and had a nearly 0% failure rate.
Here's a short preview of the 2019 Swadge doing its thing:



Here's a longer video describing all the 2019 Swadge features and how to use them:



Here's the longest video, a panel at Magfest about the design and creation of the 2019 Swadge. The slides are available online. My bit about the firmware is at 36:30 if you want to skip ahead:



We even had an instruction manual and mounting guide for 2019, which were firsts.

The community got into it as well. They even found most of the easter eggs:

• Super Swadge 2019 Easter Egg Hunting
• Swadge Easter Egg
• 2019 Swadge Modding?
• Super 2019 Swadge Wattage?
• If you got a Swadge, read this! (Also, feedback thread)

Swadge 2020

It's another project for Super Magfest! This year the theme was inspired by Donkey Kong, so we made barrels (green for staff and merch, black for supporters) and a banana (yellow, of course, for crazy-tier supporters). The official product page is over this way.
The 2020 Swadge has seven modes:

• Tiltrads, a tilt controlled Tetris-like game
• Snake, just like you remember on old Nokia phones
• Joust, a multiplayer dueling game inspired by JS Joust
• Maze, a tilt controlled labyrinth
• Gallery, a place to view GIFs and listen to music
• Colorshake, motion-reactive LEDs
• Music, a tilt-controlled single-voice synthesizer with pitch, tempo, scale, and rhythm control

The entire project is open source, and you can find it in these GitHub repos:

We made some 3D renders this year with KiCad:

I was on a panel about the design and creation of the 2020 Swadge, which you can view in its entirety below. The slides are available online too.
