This box is a GPS mystifier physique as a wedding gift by Mikal Hart . It only opens when it ’s in a specific locating , and the puzzler involves attain just where that locating is .
The box has a button and an LCD display on the eyelid . When you weigh the button , the presentation will show you how far , in kilometers , you are from the goal location . It does n’t give you focal point , so you need to triangulate where you ’re supposed to go via trial and error . Oh , and you could only press the clitoris 50 time .
There ’s a moderately sweet disguised back door built - in as well , just in typeface the stamp battery dies or the GPS social unit die .

Spoiler : the corner only opens when bring to Île - de - Bréhat , France . As for what ’s deep down ?
With all the electronics , there was n’t much room inside the loge for anything too solid . I put in a few local ( US ) gift scorecard to entice them to chat soon , a set of Kazuo Ishiguro audio books ( on a USB key ) , and an too maudlin wag . And of class , as I luff out in the lineup , if either of them fancy doing a petty Arduino development , there ’s a perfectly secure Duemilanove to encounter with , not to mention an LCD , a servo , and a GPS .
I guess the puzzler itself is present enough , really . Pretty coolheaded stuff and nonsense , no ? [ ArduinianaviaMake ]
