Love the project and progress made, along with the ESP32 ANT!

But to be more involved and support a project like this I really would need it to be based on a board with proper weather resistance! Hope you find that as an option in the future.

Within 10 seconds I was convinced I needed to try this. For me, the next step for this is taking all the sensor data recorded for a ride, and loading it into my own fitness tracking database that I own, control, and isn't tied to someone else's profits.

intervals.icu?

Looks good, but unless I'm severely mistaken it's a SAAS, not self hosted. As long as it's on someone else's service I don't own it and it's not under my control.

I openly admit, I have not spent much time researching this subject, was just in the back of my brain as I migrate away from SAAS and IAAS.

This is great. One suggestion I have (for these types of projects in general) is to include a BoM and price estimates. Make those front and center. Even though prices shift they give people ballpark estimates for deciding "do I want to spend time on this" or not. It also shows a log of clearly supported hardware and even makes it easier to track tweaks for different hardware as people contribute to your projects.

This is great, I just saw your post on X. I'm also building a bike computer! eInk is the right display tech. I think this will do really well. It might need a UV filter. That said, I don't love needing a separate device (hence, I don't own any bike computer). This is just my preference, but I really prefer to just plop my phone on my handlebars. So I'm building a bike computer app for iPhone: https://x.com/mholt6/sta…

"this is just my preference, but I really prefer to just plop my phone on my handlebars"

It's not a preference. There are a slew of issues around physical damage. Running out of power is far more of a problem than you make it out to be. There are major visibility issues (thankfully Garmin is working on this by continuing their idiotic OLED push /s) and water ingress issues. 1M submersion rating is NOT "driving rain while riding at 15-20mph."

The only people I see with phones on their handlebars are newbies.
