Re: the n810 as a bicycle computer
 

Making noise: Good. Their Java stuff does that, but it plays back velotones (like ringtones, get it? :rolleyes:) at specific speeds. (Apparently it'd have done specific velocities, but they were too cheap to add GPS.) They lack text-to-speech, so they can't do reading off whatever speed you're at.

Making noise mixed with music, in only one channel: Dead simple, and already done. I use this when playing mp3s with the device in my pocket, to read the track title when skipping tracks. Check it out here.

Speech to text / voice commands: Looks possible, but not done yet. A better bet would be duct-taping a BT remote (plain HID remote would work, but wiimote might have some cool accelerometry application here) to the bars, and using that.

A bike computer basically just takes the input of a little switch that is closed every time a magnet on the spoke passes by the stationary thing on the fork. It seems to me that we just need a little hardware thing that reads the switch "clicks" when the wheel turns, and oh, yeah, a handlebar mount for the tablet. The handlebar mount would be cool for other reasons, too... Hmmm, now I'm going to look into that. Even for GPS and a bike-jukebox.

Handlebar mount is pretty easy. I have my N800 mounted to the handlebars of my motorcycle with a RAM mount. One issue with the N800 is the outdoor screen visibility sucks.

Re: the n810 as a bicycle computer
 

I bought a bluetooth GPS (holux slim240) for use with my N800, then bought a Nokia 6120 (went for Nokia to keep charger compatibility with the N800)

by chance I then found Nokia sports tracker for S60 phones, which sits on the phone, and tracks my ride/walk etc. It also logs any photos I take enroute with the phone. I can then upload them from the phone to the sports tracker website which displays all the workout data, and the track plotted on google maps. Really really cool stuff.

The main site is also very N8x0 friendly. Much better than taking your tablet mountain biking I think.

Re: the n810 as a bicycle computer
 

Yes, if you have an S60 phone. As I do not, then taking my tablet when I go wandering in the backcountry is required.

Re: the n810 as a bicycle computer
 

So did anyone find a decent APP to substitute for a bicycle computer?? Last weekend the wife and I went for a leisurely 16 mile ride (I'm gonna be sore for a while). I used Maemo Mapper and it did a great job capturing the track and displaying MPH, but it was a real PITA to go through the menu's to get the distance from start... Would live if that would be an option to leave displayed on the screen...

Or is there a decent GPS based trip computer that would display Speed, Avg speed, top speed, altitude, track file (map not necessary), distance from start.. there are a bunch of other things I think could be done, like total distance for the year, etc..

Anyway if there is something out there then I would love to know about it...

Thanks
