Matt Blythe provides a complete guide on how to make this Valentine’s Day Puzzle Box. The box can only be opened by rotating it in a correct sequence of orientations. There are four difficulty levels: easy, medium, hard and impossible.
After I saw this post on hackaday.com about ST Microelectronics giving away STM32F3 Discovery boards for free, I knew I had to have one, but I didn’t really have a specific project in mind for a while. Then, one day I remembered a reverse geocache box that was also featured on hackaday, and realized that I could do something similar. The F3 Discover board includes a 3-axis accelerometer & 3-axis gyroscope, so instead of using GPS, I would only have the box open when it was rotated through the correct sequence of orientations.
