- Hack Details: I want to build a locked box that can only be opened by solving molarity and concentration calculations. There’ll probably be a treat inside for the capable student who solves the basic arithmetic.
- What you need to make it happen?: A suitable box (could prep something in advance?), a solid way to lock it (maybe a solenoid?), microcontroller, screen and keyboard (I have a wee usb numberpad if that’s useful).
