I attend conferences regularly, and for years I’ve wanted a badge that makes it easy for people to find me online.

In 2019, I attended defcon and built defpi, a goofy raspberry pi powered badge.

While that was fun I wanted a bit more turnkey and I found just what I wanted with a Badgeware Badger (nerdy domain hack badgewa.re).

Since my use case is to just have my socials via QR I chose the e-ink version as it made the most sense.

So what does the Badger come equipped with?

• RP2350
• WiFi
• 1000mAh battery
• USB-C
• MicroPython

I might not be the biggest Python fan but in the age of AI does it matter? I just ask Codex to help me get the desired outcome I'm looking for!

So Codex and I cooked a few hundred lines of Python and boom my profiles are only a QR code scan away.

Let's take a look at my default badge screen in all its glory.

Social screen.

All in all it's pretty simple, get you to either my LinkedIn or my personal site.

The crazy thing is the simulator lets me test the code before I deploy it to the badge.

make sim and I'm able to test it locally.

Then a simple make deploy while the badge is connected and it deploys it all.

You can check out the code repo if you wanna steal slopfork my setup.

make sim

Happy conferencing, folks!

PS: If you're going to be in Dallas for Commit Your Code 2026 come find me and I’ll show off the badge.
