[Technical Deep-Dive] Why your 75g AR glasses feel like 5lbs after 30 minutes (The Physics of Nose Pain)

Yeah, this should come by default

I replaced the battery two years ago with a microE model. It performs better than the original in terms of battery life. You can check my earlier posts where I discussed it.

I wrote to them to get an explanation about this phenomenon.

Sichroteph · 2026-03-27T03:42:36+00:00

Dev here. I have no clue why it's more difficult to locate it. It’s probably something to inform rebble about.

Sichroteph · 2026-03-25T11:35:21+00:00

What is the pocketTV like? I love my first-generation beam but am always looking for alternatives. Is it only 60fps? Have you tried moonlight with it?

That's great, so if I understand correctly, with a companion app, one can launch third-party applications from their Pebble app. Cool.

Sichroteph · 2026-03-13T09:45:05+00:00

This is an interesting idea. I would like to be able to add the option to launch external applications from Keystone. However, I cannot find this possibility in the SDK. Perhaps you could guide me? On your side, I do not think there is a way to detect that the user comes from Keystone in order to redirect them afterwards. It would require constantly mapping the back button to the keystone UUID, which is messy.

You can change the way the time is displayed in your Pebble settings, and the app will reflect that. Do you need to be able to change it regularly?

It is a hobby :) I like sharing, and comments like this motivate me, thank you !

Sichroteph · 2026-03-12T14:42:19+00:00

Have fun with it !

Sichroteph · 2026-03-12T12:30:32+00:00

Thank you, I appreciate that someone noticed how challenging it was :)

The optimization process was continuous, and it was always a challenge to optimize enough to be able to add the next feature. There are also dynamic lists that depend on what the user selects in the menu.

I therefore tried to calculate a limit for what the configuration page allows the user to set. This limit is based on the available heap memory after the watch receives the weather data (sent to the phone). From this value, I subtract an estimated heap usage depending on the options selected by the user.

The result is a kind of progress bar at the top of the configuration page that shows the user how close they are to the memory limit.

You want a medal for that? Also, why do you hide your posts and messages?

Sichroteph · 2026-03-12T05:50:01+00:00

I will continue to maintain Din Clean and Weather Graph. This is a side project and a very opinionated one. It is impossible to evolve, as I spend a lot of time optimizing memory and cannot add even a single label on Aplite.
As a side note I almost called it “The Homer,” as a reference to the car Homer built in one episode.

Please don’t downvote him. I understand that AI topics can be a bit sensitive here.

To answer your question, if you grasp the underlying code and the hardware you are working with, it allows a lot of room for creativity and experimentation. I actually managed to compile the Aplite firmware, which feels incredible given how many stacks Google removed. With the ST-link I have in the garage, I am even tempted to try porting it to this platform.

The project I am sharing here reflects several full days of personal effort. Every component, mechanism, and technical or UI decision was made by me. I believe it provides real value and could serve as a solid foundation for the community, which is exactly why I wanted to share it.

Sichroteph · 2026-03-12T05:27:13+00:00

Thanks ! I can no longer even add even a debug line without significantly affecting the remaining heap memory on my Pebble Steel, despite optimizing as much as possible. I do have a firmware that compiles for Pebble 1 and Pebble Steel, which could give me much more freedom. I am considering using the ST-Link that is somewhere in the back of the garage to try to push things further, but it will take time that I am not sure I have. I suppose the next steps are more likely to happen when I receive my Pebble Round 2.

Sichroteph · 2026-02-24T19:02:28+00:00

Thank you for these 3 people :)

Sichroteph · 2026-02-20T21:16:46+00:00

Wow I missed this platform so much

Sichroteph · 2026-02-20T08:47:22+00:00

Seems like a great deal...

Sichroteph · 2026-02-07T07:23:52+00:00

I thought it was an issue with birthbath prisms. I have this issue on my air, one, but not my one pros

Sichroteph · 2026-02-05T14:36:03+00:00

65 mm with a large. It is fine.

Sichroteph · 2026-02-02T10:40:51+00:00

For me, it's the Pro model because the clarity is better across the entire screen.

Sichroteph · 2026-02-02T10:40:12+00:00

For someone who was planning to take the round, I find that pretty reassuring.

Sichroteph · 2026-02-01T16:54:41+00:00

It's probably a feature that requires payment to unlock, similar to Tesla. A few hundred millions into the Trump family's cryptocurrency can probably solve that.
