Sadly the app doesn't work. There is no popup asking for microphone permission.

EDIT: I see there is an open issue for that on github

These are valid points but the upside of vr is still much bigger than the current downsides. The ability to explore worlds as if you're actually there is something no other medium really offers.

if you're experimenting with hrv/biofeedback then you might find Aidlab 2 interesting, it gives RR + GSR in one wearable (fyi I am the author)

yes,, render feels like the most natural next step right now (similar mental model). Still kind of nostalgic about Heroku, had really good times with it.

Same here! Still on a streak since day one

hey guys, we’ve had a chance to chat a few times. Fingers crossed for your launch here. Have you thought about Show HN? Your product is clearly needed, and I’ll always support standardization /open standards.

by tracking sleep, what exactly do you mean by that? sleep phases, sleep score, sleep duration?

the open-source models will catch up, 100%

No, and no nudity, no reference images. Example: 'athlete wearing a health tracker under a fitted training top'

'athlete wearing a health tracker under a fitted training top'

Cool, but it's still unusable for me. Somehow all my prompts are violating the rules, huh?

Congrats guys on your release. I tried new VitalLens side by side with my medical grade tracker (Aidmed One) but the respiration numbers were quite off.

Curious if you've done any comparisons against actual hardware (chest-based or contact PPG), or if validation is mostly dataset based for now.

It's not sexy, and as a result an overwhelming majority of the population is unaware about how to avoid succumbing to it

When I started building an ECG Holter in my early 20s, I tried to get some friends to use it and kept hearing "yeah, but it’s not exactly sexy to wear that thing." That’s when it hit me how little people care about prevention until something goes wrong. We still have a huge awareness gap to close.

So I went on X after a long break from social media, and my feed is full of tips like this one:

Growing on X is so simple I’m shocked it works.

100x comments a day

10x posts a day

15x DM’s a day

1x thread a day

1x email a day

This is how you grow your presence on X.

Even if having a presence matters, how can you actually say something meaningful if you post 10 times a day - there's no way (unless you just repeat yourself). Hopefully my algorithm's just gone weird but sadly the people I used to follow stopped posting.

Hey, can you join our Discord: https://discord.gg/sPay3Xm? Reach out to me personally (@guzik1) - happy to help you with that as we've already had a few people who integrated with rpi, so I can share some tips and examples.

Thank you! We've integrated a different chip for measuring chest movements

sadly, comfort for chest straps compared to hand straps is a known issue and ours is definitely no different. Wve done a bunch of tests, tried different materials/custom solutions, and honestly we're still clueless how to make it significantly better (if anyone here works in textiles or wearable fabrics, I'd love to connect). So yeah, if wearing your Garmin for more than an hour already feels uncomfortable, ours probably won't be much better in that regard

for regular users, since the device itself doesn't have any interface, we need to send at least some data so they can see it somewhere. the natural place is the phone, but not all of our professional clients liked viewing long ECG recordings or detailed metrics on a small screen, so we built cloud access mostly for convenience .

(to be clear - if a developer wants, they don't need to send anything to us)

Thanks! Yep, the interface for a shell is available here: aidlab.com/developer/debug we are using Jquery Terminal + Web Bluetooth (sadly, I think it's not under active development anymore)

and yeah, when we started years ago, it felt natural that the next step would be to measure glucose from blood but the truth is with the current state of science, it's still not possible to do that 100% non-invasively.

we don't have any plans right now to build a blood glucose sensor (although we already support a few external sensors - but not glucose monitors yet)

I am glad that we decided to pick CSV as our default format for health data (even for heavy stuff like raw ECG). Yeah, files were bigger, but clients loved that they could just download them, open in Excel, make a quick chart. Meanwhile other software was insisting on EDF (lighter, sure) but not everything could handle it.

We thought for a long time about using protobufs in our product [1] and in the end we went with JSON-RPC 2.0 over BLE, base64 for bigger chunks. Yeah, you still need to pass sample format and decode manually. The overhead is fine tho, debugging is way easier (also pulling in all of protobuf just wasn't fun).

That makes sense, thanks a lot for clarifying! I'll send you an email.

Some are for free:

- aidlab.com/datasets

- physionet.org

glad there are a few supporting comments including yours (I thought I was the only one who felt the criticism was excessive)

thanks for linking to my landing page!

Here's the backstory of how it all started: https://howtoware.com/aidlab (good reading for anyone wondering how to start a wearable startup)

Ha, thank you for that! I actually didn't have prior experience in wearables. My background was in mobile app development. I co-founded a company during the app boom, and we built a lot of iOS and Android apps. The transition into health sensors happened pretty organically and I also felt there was nothing that let me measure my own data and make use of it, so I decided to create a wearabke + free SDK for that. There is a quite nice article of how it all started here: https://howtoware.com/aidlab (good reading for anyone wondering what the struggles are when running a wearable startup).

Gee, today is my birthday (36). I've never managed to get anything I've built to the HN front page. Always wondered if that means my ideas just weren’t that interesting, or if it's just the luck of the draw.

*edited my original comment without mentioning my project*

let me piggyback on this thread because maybe there’s a kind soul here who knows the answer. I set up some simple cron jobs in Claude Code that run every few hours. I am on the Pro plan and unfortunately, I cant fully solve this one problem: I keep getting the error:

Invalid API key · Please run /login

I know there are a lot of github issues about this but most of them dont seem to directly apply. The weird thing is: when I run the exact same command manually in my terminal, it works fine. When run via cron, it fails. I suspect it has something to do with how Claude CLI stores the session token or environment variables, since cron doesn’t run as a full login shell. I already tried wrapping the command in bash -l -c "..." which helps in some cases, but not consistently. Has anyone here figured out a clean, reliable way to run Claude CLI from cron without having to manually relogin every 5 hours or so? Or is it only restricted for paid anthropic API Key?
