Some applications written for the SHA2017 badge and the card10 badge from the Chaos Communication Camp 2019.
alarm, card10 hatchery
A simple countdown-like alarm, which reminds you to check the long rinse queue again or the like.
fractal_tree, card10, sha2017 hatchery
Draws multiple fractal trees. Quite useless btw.
This application was written for the SHA2017 badge and was ported to the CCCamp's card10. It should run on both badges and perhaps also on this Hacker Hotel 2019-thingy.
matrix, card10 hatchery
Display a Matrix-like animation with a configurable overlay (none, nickname, time) and optionally blinking LEDs.
The overlay can be switched by the bottom buttons and the LEDs can be enabled/disabled by the top right button.
pixelflood, sha2017 hatchery
Pixelflood server on your badge.
sensorthingy, card10 hatchery
The SensorThingy interacts with the card10's sensors and logs them into a JSON file.
