Show HN: Glasses to detect smart-glasses that have cameras
Hi! Recently smart-glasses with cameras like the Meta Ray-bans seem to be getting more popular. As does some people's desire to remove/cover up the recording indicator LED. I wanted to see if there's a way to detect when people are recording with these types of glasses, so a little bit ago I started working this project. I've hit a little bit of a wall though so I'm very much open to ideas!
I've written a bunch more on the link (+photos are there), but essentially this uses 2 fingerprinting approaches: - retro-reflectivity of the camera sensor by looking at IR reflections. mixed results here. - wireless traffic (primarily BLE, also looking into BTC and wifi)
For the latter, I'm currently just using an ESP32, and I can consistently detect when the Meta Raybans are 1) pairing, 2) first powered on, 3) (less consistently) when they're taken out of the charging case. When they do detect something, it plays a little jingle next to your ear.
Ideally I want to be able to detect them when they're in use, and not just at boot. I've come across the nRF52840, which seems like it can follow directed BLE traffic beyond the initial broadcast, but from my understanding it would still need to catch the first CONNECT_REQ event regardless. On the bluetooth classic side of things, all the hardware looks really expensive! Any ideas are appreciated. Thanks!

Show HN: Turn your site into a demo video with one URL
Tired of recording the same product demo 10 times and still not being happy with it?
That’s basically why I built AutoAds (autoads.pro).
The idea: you paste your site’s URL, and an AI pipeline does all the annoying stuff for you, fully automatic.
What it does
- You paste the URL of your site (SaaS, e-commerce, portfolio) - An AI pipeline visits the site and analyzes the content (sections, copy, visuals, CTAs, etc.) - It generates a screen-recording-style video of your site: - scrolling and navigating - focusing on the key sections - It then does an automatic edit: - short cuts - "promo-style" pacing - wraps everything inside a Mac mockup so it looks like a product video - In parallel, the AI generates: - a voiceover that explains your product - subtitles synced with the voice
End result: you get a ready-to-use promo video (MP4) without opening Loom, without a mic, without a camera.
What it works for today
- SaaS products - E-commerce sites - Portfolios / personal sites
There’s a free plan so you can try it with your own site (no credit card).
Feedback I’m looking for
- Would you actually use this instead of recording a manual demo? - What would you want more control over: script, voice tone, mockup style, video length? - What’s missing for you to feel confident using it on your landing page or in paid ads?
Link: autoads.pro
If you try it and get a cool (or terrible) video, I’d love to see it and hear what feels off or missing.
