Free geolocalization using Leaflet

By mvuilleu, in Programming, may 12,2018.

OpenStreetMap logo by Ken Vermette [CC BY-SA 2.0]Two years ago, we showed you how to geolocalize a vehicle without using a paying service, with a Yocto-GPS and the Google Maps API. But this month, Google decided to make the use of the Google Maps API billable. This gives us the opportunity to have a look at alternatives based on free and collaborative development, which no longer have anything to envy Google.

Implementing a hanging scale

By seb, in DIY and Android, may 04,2018.

This week, we are going to do some tinkering and build a hanging scale with a Yocto-Bridge and an Android smart phone. The aim is to weigh objects ranging from a few hundreds of grams to about twenty kilos, in order to weigh objects such a model air planes or bikes. Strangely, two widely popular hobbies at Yoctopuce :-)
