While I'm here, I find that when on battery, the keycaps do not stay lit. They do on USB. Is that a bug or a feature? (Save the battery, mayybe?)

We have a discord server up for those hacking on the badge. https://discord.gg/9DdhhPrV

Same here and the help screen is about as useful as the reproductive organs of celibate clergy!

Just got my badge the other day .. issue, my wife threw the packaging away that had the code. Is there a way to reset it? Or are the codes all the same?

https://plus.defcon.org/recover.html -- That should help

Invalid invite

For anyone who has not found it yet, you can access the badge through a serial terminal. For example, on mac you can use 'screen /dev/cu.usbmodem123451'

Did you try to generate more of those strings?

I'm in the same boat!

The lanyard is a USB-A to USB-C cable. Use it to connect badges to each other or to your computer.

Did those of us who went virtual this year get stiffed on a lanyard cable? I got a fabric one.
