Badges

Hello, hi!

Hi there! My name's Kay Ohtie! I'm a coyote of the air-filled sort, and either you clicked your way to this page from my website, scanned your way here with a QR code on my e-paper badge, or tapped an NFC badge! Either way, thanks for dropping by!

This page is here to document the badges I'm wearing, especially the signatureless e-paper ones, for artists who created them and perhaps a little information about them.

But first...

What's that box thing you're wearing??

That is an e-paper badge I built! I came up with the design and had a proof-of-concept (read: just the display with an image) at MFF 2018, and had the badge working and live for FWA2019!

The badge is comprised of the following components:

All these are connected up, with images loaded onto the SD card. Every few minutes, the microcontroller wakes up and sends a new image to the display from the SD card. The battery lasts up to 48 hours in ideal conditions, but I tend to recharge it daily.

The display itself is capable of displaying three colors: white, black, and yellow. There's another variant that does red instead of yellow, and so red is commonly used in the images pushed to these displays to make sure it renders in the 'color'. Images below are recolored from what they are on the SD card, red, to be similar to the golden on the display.

Speaking of images...

Barnem

These were really my first e-paper badges, done as a proof of concept for me by my wonderful friend Barnem, and they're very cute! The blushy first one was designed around a smaller display I started to use with a Raspberry Pi Zero, but opted for the larger display powered by a Cortex M0 instead.

Kit did the first full-display image last year, taking advantage of every pixel for a fun effect!

Frengers

One of my new badges this year! Frengers has done some pixel work in the past, and did an incredible job on this limited-palette image! The dithering to get the hair color as almost a 4th color is great! Much thanks for their work!

Reluctant Draggin

I reached out to Reluctant to see if he'd be down for doing a badge, and he wasn't remotely reluctant to do it! Is this false advertising? Cute blimpiness either way!
