the model is a set of weights, you can take a snapshot and test it. Reinforcement learning itself is largely testing and tuning.

be careful how you mount it, make sure that there is enough dampening. people have had issues with excessive vibration and damaging the OIS and focusing motors in the cameras.

Thanks, hasn't been a problem for me.

~15,000km with this phone. Tens of thousands more on older phones all the way back to the 5s. Which of course wasn't nearly as good: no always-on display and had to use the Quad Lock "poncho" in the rain.


My road bike handlebars killed my iphone camera fwiw. Into the saddlebag it goes now.

Quadlock makes a special dampening mount for this reason.

what is insane, is that ble is largely unsecured in modern implementations. when testing, i kept picking up everyones whoops/assorted ble devices spamming out heart rate data to whomever wanted to connect.

note using a phone mounted to a bike or motorcycle can cause damage over time to the camera assembly especially the motors used for OIS. depending on how much you ride or the quality of the roads you ride, it could be an issue.

your project does look amazing. sorry that the appstore team is holding things up.

RE: ANT+, a hackrf one and fable was key to the hack.

I attribute my iPhone 7's camera failing with mounting it on my bike.

I’ve wondered about this. Does it shake a lot less when it’s in a pocket for the same ride?

Presumably yes, as every cyclist ever does that.


refresh rate is sort of a non issue. i can push the refresh rate to up to 20Hz, it is largely unnecessary for this project.

it has a nice backlight (basically identical to a kindle display)

color is fair, but i dont miss it.

i do absolutely love how readable it is in direct sunlight (when im mostly riding)


I find colour useful for a navigation map, mostly. I think the 4-colour eInk displays would be plenty for that, although they have refresh constraints iirc.

A good UI design would mostly avoid the need for colour.


i can push it as high as 20Hz.

For me, it matters only when I'm futzing with the map: dragging around or zooming. For the rest of the info on the display, anything more than 500ms interval seems like a waste of power.

yes me too. i may be working on something...

technically i dont think the coros uses an eink display. but it is definitely one of the cooler bike computers.

I hadnt heard of it. I will check it out.

PMTiles is the underlying technology I believe. We use it on oceanconnect.ca and in my opinion it’s pretty awesome. Very efficient to store and retrieve, and cut our S3 PUT request costs by something like 90% across the project.

i have been using it in my car during commutes for testing. modern eink displays can do pretty high refresh rates. i think i can hit 20hz.
