A puzzle I designed for Square's 2016 CTF. I was inspired by DefCon's badge puzzles (significantly easier to solve however).
Want to try it out? Reach out to me and I might be able to mail out a spare.
- Feel free to abuse the hardware; it's yours.
- The board is easy to power from a wide range of sources. Don't go over ~35V. Some components might heat up a little.
- Solving the puzzle may require using sharp or hot tools (knives, soldering iron, etc.). Handle your tools carefully.
Andy, Todor, John and Matt helped me go from prototype to a finished board; answering my various questions along the way. Cedric and Chris helped solder some of these.
