I should have gone for a ride today so I could post a photo here and not be completely off-topic… If only my uni wasn’t broken. Here’s some from ages ago:
Nelson BC.
First big tour. Miss those dreads…
Mowcius,
Excellent. I knew about Hal-effect sensors but it hadn’t occurred to me they might be sensitive enough to detect spokes themselves! I wasn’t excited about the prospect of mounting 36 regular cyclocomputer magnets to my wheel. I’ll have to look into it more.
Yes, I will probably end up using the spokes as a photo-interrupter. Or, when I get my MountainUni disc break, I was thinking of using that. I like the simplicity of only having electronics on one side of the frame, though.
Either way I still need a method of tracking where on the wheel the signal is coming from, so I’d probably keep the taped rim if I used a spoke-based interrupt, etc. Or do some fancy software magic that used the valve’s interrupt to reset the counter…
Time to dust off my IRC client.
