We're handing everyone a ESP32-S3 development board with a touchscreen, Wi-Fi, Bluetooth and a battery. Your challenge is simple: build something insane.
Expect teams of two, a room full of builders, and a day to turn an idea into a working prototype.
We'll provide:
- A ESP32-S3 development board for every team
- Food, drinks and snacks throughout the day
At the end of the day, each team will give a 1 minute demo. Projects will be judged on creativity, technical execution and overall usability, with prizes for the standout hacks.
Schedule
- Arrive by 10:30am
- Demos begin at 4:00pm
- Wrap up by 5:00pm
Places are limited and we expect this to be heavily oversubscribed, so apply early if you'd like to join us.
