This week, we are going to talk about a topic which is not linked only to Yoctopuce modules but which will certainly be of interest to those of our readers who use Raspberry Pi machines or other Linux systems: How to automatically run an application when Linux starts.
Do you remember the GT-521F52 fingerprint reader that we tested three weeks ago? We found a nice and fun application for it...
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.
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 :-)
We discovered somewhat by chance the ADH-Tech GT-521F52 fingerprint reader. As it is really affordable, less than fifty US dollars, we decided to buy one two, to see what we could do with it.
