Just ordered my FreeRunner.
I want to use it as bicycle computer.
These are just ideas and wishes - not worth to make a separate wiki page.
Due to the relatively high current consumption of the Freerunner a power supply from a hub dynamo seems to be unavoidable.
I have a evaluation board of a Linear Technologies step converter which I will use at the beginning.
Of the travelled track and also of the upcoming (hopefully OSM will soon provide elevation information of the roads)
Garmin Etrex Legends trip information display is to stupid. I want infos for the current day and for the time since last break.
The GPS does not give sufficiently accurate vertical speed. A barometric sensor would be nice. Calculation of the vertical speed by integrating the accelerometer readings also not accurate. But maybe it is possible to use the accelerometers to measure the slope of the road. How to calibrate it? Is it possible to automatically calibrate it from GSP reading?
By measuering the increase of the total acceleration not by change of the acceleration angle.
