So by combining a nice box and some hardcore electronics nerdiness I've made a nice christmas gift for my wife. The LoveBox is a small box that when opened displays a random message of love to the viewer.
Step 1: Alternative usages
So in order to get the world spinning the LoveBox can be changed into a DecisionBox by altering the software to give a random answer of "YES", "NO" and once in a while even an "MAYBE" when the box is opened. That's the perfect gift for the undecided decision maker. ;-)
For gamblers the box could be adapted to show lotto numbers when opened.
The possibilities are endless as most people needs to be told something or make decisions....
Step 2: What you need
- A nice box
- A alphanumeric display
- A microcontroller
- A 74HTC138 (3-to-8 decoder)
- Some resistors
- Two 3-volt batteries
- A microswitch (NC)
- Wires, hot glue gun, soldering iron and other small tools.
