## Projects
* [Verkehrswende Wordpress Locations](https://github.com/steampixel/RadentscheidWordpressLocations) - This Wordpress plugin can be used to track infrastructural problems like missing sidewalks or bike lanes and provides users with interactive maps. Users can also contribute to the map by uploading coordinates and images.
* [Radmesser](https://interaktiv.tagesspiegel.de/radmesser/index.html) - The Tagesspiegel, together with physicists, experts in artificial intelligence and designers, has developed its own sensor to find out how close car and bicycle drivers are in Berlin's city traffic.
* [Openbikesensor](https://zweirat-stuttgart.de/projekte/openbikesensor/) - Following the example of the Radmesser, the OpenBikeSensor was created in Stuttgart at the Zweirat. The Radmesser is a project from the Tagesspiegel in Berlin; a small technical device on the bike that measures the distance from overtaking cars while driving. Since this is not only a problem in Berlin, but also here in Stuttgart, we want to take care of it!
* [fixmyberlin](https://fixmyberlin.de/planungen) - The Berlin-based FixMyBerlin project analyzes all major roads in the city according to their cycling infrastructure and keep track of where construction projects are really being implemented ([source code](https://github.com/FixMyBerlin)).

Anschließend wurden nur Strassenabschnitten visualisiert, auf denen Tempo 50 gilt (maxspeed=50) und tatsächlich nur <33km/h gefahren wird.

Da der verwendete Step-Down-Regler nur maximal 25 V verträgt, muss die maximale Spannung begrenzt werden. Dies erfolgt hier durch zwei parallel geschaltete 12-V-Zenerdioden, die die übrige Energie »verbraten«. Die Dioden sind auf einem Temperaturschalter montiert, bei 60°C wird der USB-Lader abgeschaltet. Höhere Spannungen wären hier wünschenswert, damit die mühsam erstrampelte Leistung nicht schon bei normaler Fahrt und vollem Handyakku in Wärme umgewandelt wird. Doch die zusätzliche Leistung lässt sich dann nur schwer wegkühlen (@ Andreas Oehler: Danke für den Tipp).
