About Me

I'm French, 35 years old. I lived in München, Germany until 2016 and now live in Singapore. I studied electrical engineering at the TU of Munich as double-degree student (exchange with my engineering school in France).

Equipment

Nowadays, I simply use my smartphone with the Geohash Droid app.

In the beginnings, I used the following equipment (back when I lived in Germany):

• Garmin eTrex 20 for geolocalization and track logging.
• My Peugeot bicycle to ride to the hashes.
• Nikon Coolpix L3 camera, very compact, to take photos of the expeditions.
• Additionally: an iPhone to locate me and for Google routing. MotionX GPS Lite for GPS coordinates and Google Maps for orientation.
