anybody remember the game Myst? Well, [Michael] and his girlfriend have been playing quite a bit of it lately, so for her birthday, he chose to make her something inspired from it.
For those unaware of the classic that is the Myst series, it is a set of games that started back in 1993 where you assume the role of the stranger who gets to explore other planets (called Ages) to resolve various logical and mechanical puzzles.
Anyway, [Michael] got his girlfriend tickets to visit GC319QK (a geocache site requiring diving) — because the gift is a relatively small token, it was logical for [Michael] to make a fancy box for it — and that’s exactly what he did. It’s a peculiar little wooden box with LEDs, a button, a latch, an unplugged wire, different rods and unusual looking sensors — and it is a very smart little puzzle.
We could discuss to you how it works (with the Arduino, phototransistors and maybe the source code), but instead we think you’ll delight in viewing [Michael’s] video of it.
Now because the present is for geocaching, we’re practically amazed he didn’t include a reverse geocache puzzle in it too!
