[Chris] shares a dorm room with five other people. When living with others its important to stay on top of cleaning and to do so equitably the sextuplet came up with a well-planned whiteboard of chores. The problem lies in getting everyone to do theirs in a timely manner. To help facilitate this, [Chris] came up with a system that lets roommates swap chores, giving each other IOU’s for future duties.
The system uses an Arduino board along with an RTC chip for precise timekeeping. The user interface is made up of a graphic LCD and a keypad with everything mounted inside of a cardboard box. [Chris] shows off his system in the video after the break, spending the majority of time on the debt system. The roommates have a pot of money for group groceries and this system will let you know where everyone stands. But according to his written description this also stores the calendar of chores that need to get done, and will let you trade with one another to fit your personal schedule.
So now the issue is getting everyone to use the system. But we don’t think that’s going to be too tough since all six of them are computer scientists.
