The new-year's reception at our company led to a semi-regular get-together of some colleagues to help each other with various projects. I noticed the sci-fi contest on Hackaday and we started brainstorming on a good idea for a project. HHGTTG is a favourite among our little group (it's no coincidence our company street address is at 42), and taking inspiration from there we found that with the limited time to the contest deadline a real life (though limited) version of the electronic thumb should be feasible.

We found a ride sharing service with a well documented API and the current idea is to have an ESP8266 poll the service for rides from our current location, provided by a GPS breakout board. User interaction through a small oled display on the device and some 'flat switches and dials'..

Will update the project once we've started hooking up the hardware parts and writing code to make it work. OH! We'll need a nice 3D printed enclosure, of course.. :-)
