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.

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?

No, and no nudity, no reference images. Example: '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?

Ask HN: Any Hardware Startups Here?

guzik — Mon, 10 Nov 2025 16:22:19 +0000

AI is eating the world. Feels like every hour there's a new SaaS or GPT wrapper launching. That's cool, but I'm curious who's still building hardware? I'm keen to meet those in our community taking on the often-quoted "hardware is hard" challenge.

Would love to hear what you're working on, even if it's just a prototype: anything that involves devices, sensors, rockets, robots, cameras, wind turbines, solar panels, self-driving cars, wearables, medical tech, anything that actually touches the physical world.

Remember, no venture is too small or niche!

guzik — Sun, 09 Nov 2025 09:54:53 +0000

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.
