Fresh hacks every day
[Troy] recently got his hands on a greengoose starter kit and like any HAD reader would do, proceeded to probe it mercilessly.
The greengoose appears to be some sort of location-tracking device which reports back to a server on the position and location of radio transmitters relative to it. [Troy] managed to not only get the base-station’s firmware, but … Read the rest
Here’s a talking reverse geocache puzzle box which [Erv Plecter] built as a wedding gift for his friends. The box itself isn’t really the gift, but a surprise delivery system for a collection of cash from the couple’s circle of friends to go toward the honeymoon. We think this is about fifty times more fun that getting a fat envelope … Read the rest

The orange box is a metal cash box, and there’s a … Read the rest

The hardware actually turns out to be very simple. He needed a GPS module to gather location data, and a way … Read the rest
GPS receivers may be available for well under $100 these days, but what’s the fun in buying one when you can build it yourself? According to [Andrew], the creator of this device, he was inspired by Matjaž Vidmar who developed a GPS receiver from scratch over 20 years ago. His article can be found here and includes some nicely … Read the rest
[Davy] and his friend [Chris] were tasked with putting together a bachelor party for their friend [J], and had a little more in mind than the standard drunken revelry. To earn the privilege of partying his brains out, they decided that [J] would have to fulfill a series of tasks and challenges before joining up with the rest of his … Read the rest
The team at Eschelle Inconnue wanted to “trace a sound cartography of Islam” in Marseilles, France, so they came up with a clever little GPS walking tour powered by an Arduino, MP3 playback module, and a surface transducer speaker.
The team used a Processing app to define geographic areas where each MP3 file would play. An Arduino on the build … Read the rest
