Re: Cycle Analyst V3 preview and first beta release

heyDD- It sounds like a button or perhaps condensation problem that is causing phantom button pushes. In particular, holding the left button depressed on boot sends control directly to Setup - you primary symptom. Buttons not working is likely because one or more is stuck ON. Carefully unscrew the b...

Re: DIY electric hand cargo trailer

But is there a benefit (for example in terms of torque) using a different kind of motor? What do I lose not using a hub motor (for example are rpms fixed in other types of motors?)? I originally proposed using the hubmotor because of the fabrication simplification and the ease of upgrade - just buy...

Re: Sempu BB + cycle analyst assist not working well

The grossy asymmetric Sempu waveform in combination with the high pole count has been found to cause certain CA 3.1+ PAS difficulties. This isn't directly related to the odd pulse timing your post illustrates, but it's another Sempu weirdness. This issue has been addressed and will be released very ...

Re: Trek report on becoming more visible (for electric velomobile)

Improved visibility has only do with knees, feet, and pedaling in that they provide points of visual complexity and change for others. Tying lighting to pedal motion misses the underlying cause of the Trek observation and suffers from the rate dependence you point out. If you want to get peoples att...

Re: Cycle Analyst V2 - Menu on startup

This could simply be a failed button assembly with the left button stuck ON. Remove the four screws from the back of the case and carefully open it. Unplug the button ribbon cable from the circuit board. Now try powering up the CA to check if it boots properly. If this works, a replacement case part...
