Revision as of 08:13, 4 September 2008
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.

Power Supply
Due to the relatively high current consumption of the Freerunner a power supply from a hub dynamo seems to be unavoidable.
I skip the switch mode regulator and will use simple Z-Diode parallel to the Freerunner. Later I want to add an LED light parallel to both.
GPS
Existing Software
Getting GPS Data
On Freerunner there is no need to read from gpsd or similar. I just can get the data from /dev/ttySAC1
Additional GPS Functions
Altitude Plots
Of the travelled track and also of the upcoming (hopefully OSM will soon provide elevation information of the roads)
Trip Information
Garmin Etrex Legends trip information display is to stupid. I want infos for the current day and for the time since last break.
Location Reporting
If I have internet access via the phone during my trip I can regularily update my on webpage with location markers as shown here: http://wiki.openstreetmap.org/index.php/Openlayers_POI_layer_example
Slope, Vertical Speed
The GPS does not give sufficiently accurate vertical speed. A barometric sensor (see Variometer) 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?
Sideward Inclination of the Bicycle
By measuring the increase of the total acceleration not by change of the acceleration angle.
Road Quality
Can the road (e.i. surface) quality be recorded by measuring the vibrations with the accelerometers?
Car Counter
... using the builtin microphone. Or would it be possible with the accelerometers using high sampling rate?
Heart Rate Monitor
Are there Bluetooth Heart Rate Transmitters available?
Pedalling Frequency
Pedal sensors with Bluetooth and power supply by magnetic induction would be nice.
Otherwise USB with an FTDI chip.
Programming
Language
Python
UI
python-etk
I could not find any documentation yet. Seems to be the same as python-gtk.
I don't want to have eye-candies. Maybe eye-candies are neccessary for selling phones. Eye-candies cause eye-caries or even brain-caries. ;-) They are for gamers.
Colors are o.k. if they carry information. Color gradients of menu bars are useless and annoying.
Maybe I should directly call xlib instead of using some *tk. From python I could try http://python-xlib.sourceforge.net/ .

alternative window managers
The bicycle computer should show different values at the same time. This should be user configurable at runtime. What about having little python scripts just showing a window with one value and let the window mananger do the rest? The default window manager of OpenMoko is the Matchbox Window Manager. Are the various python window managers an alternative?

Plotting
matplotlib? might be an overkill. Anything usable lightweight available?
Jogging
Accelerometer
Mount the Freerunner to the shin and measure the damping and motion style with different shoes at various speeds. Especially interesting to watch the aging of the shoes (different damping).
Openstreetmap
- GPS-Trail currently only dicussions there
I would like to have a simple application to add map information at my current location. Say, I am standing beneath an ATM, just use a menu item "Add ATM" and typing in its name - finished. There is no need for a map display. The program just displays the OSM nodes near the current location. And you can add a new node or modify an existing node.
Other Accelerometer Ideas
- Indoor use of those GPS games
- Programming a Marble game would be more fun than playing it (Martin Senkerik is now having that fun http://projects.openmoko.org/projects/accelgame/)
- Moving within a larger virtual screen by tilting the display.
Games
Finger-usable application to play the game of Go: Somebody somewhere suggested a double click methode for keyboard input. The first click zooms the area of the keyboard the second click activates the key. I don't want this for keyboards but for Go and similar games this could be quite interesting.
More Brainstorming
Midi Input via Touchscreen
There is not much space to use the touchscreen as an ordinary piano keyboard.
What about using the touchscreen like the left hand fingering on a guitar, mandolin, banjo ore similar? The touchscreen lays in front of you in landscape mode. There are four rows, one for each finger.
| D# | G | B | d# | | D | F# | A# | d | | C# | F | A | c# | | C | E | G# | c | This layout might be to simple. Should it be optimized for easy chord playing? To come more close to a piano and common string instruments it might be better to flip the arrangment of the notes. | c | c# | d | d# | | G# | A | A# | B | | E | F | F# | G | | C | C# | D | D# |
Unfortunately the touchscreen handles only single touches (UI_Improvements#The_touchscreen). Therefore a polyphonic input is not possible.
Octave shifting via accelerometer reading?
Similiar project: http://www.neo1973-germany.de/wiki/epiano Obviously not what I am having in mind.
