Let's see what happened in the last two years.\n\nFond are the memories of the Chaos Communication Camp 2019. If you attended, you most likely took with you a little wrist-mounted bio-sensor enabled hackable smart \"watch\" - the [card10 badge](https://card10.badge.events.ccc.de). It's like a time capsule from a better world.\n\nWhile the hardware was set in stone back then, the [firmware](https://firmware.card10.badge.events.ccc.de) was absolutely not. Over time, it learned many new [tricks](https://git.card10.badge.events.ccc.de/card10/firmware/-/blob/master/CHANGELOG.md); we will show the cool things that happened since you last updated your firmware.  And invite you to ~~resuscitate~~ reboot your card10 badge with more features, better Bluetooth, cleaner graphics and better sensor support than what you last remembered.\n\nAlongside the talk we plan to host self organized sessions with workshops to help you make the most of this little gem. Maybe you don't need another smart watch? How about a BLE connected indoor climate sensor, connected to your Raspberry PI, serving it directly to your phone? Stay tuned.\n\n- https://card10.badge.events.ccc.de\n- https://firmware.card10.badge.events.ccc.de\n- https://git.card10.badge.events.ccc.de/card10/firmware/-/blob/master/CHANGELOG.md\n\n00:00
