CHALKY
CHALKY is about analog time management in a digital way. The classic blackboard becomes the output medium of the digital world and thus combines the digital and the analog.
It is possible to send an appointment, message, or comment location independently via the digital path like an app or a website to a chalk robot — CHALKY, where it will be paged out on the analog path on the blackboard.
Arduino is used for the electronic part. CHALKY is based on the main part, which controls the chalk and the sponge via two servo motors. This part is attached to four strings, which are running over eight guide rollers. Two of the strings are connected to motors and the other two are connected to weights. The weights are necessary to push the main part with the chalk against t the blackboard.
Different forms and constructions were tried, to make it as light as possible.
