Camera-Free Object Discovery and Interaction with GazeTags

Camera-Free Object Discovery and Interaction with GazeTags

Future Interfaces Group

GazeTags skip cameras: stick a year-long battery tag on anything you care about, and a head-worn IR beam wakes only what you're looking at. Future Interfaces Group gets object-level gaze sensing — plus non-visual state like kettle temp — for a few hundred bucks across a whole home.

colsto

A careful, slightly unsettling look at how faint background sounds like passing aircraft can pin a recording to within about 100 meters. Stick around for the end, where it covers what you can do about it.

Senior Engineers Are Using AI Wrong and Software Factories Are Dumb

Senior Engineers Are Using AI Wrong and Software Factories Are Dumb

Joe Maddalone

Joe Maddalone asks which engineering habits are real principles and which were just workarounds for how expensive human-written code used to be. A good gut check for any team rethinking how it builds with AI.

Wes Bos

Wes Bos built his own iPhone app to capture photos and lidar, then had Codex stitch it all into a 3D model of his house. The scanner, viewer and skill are open on GitHub, so you can point it at your own space this weekend.

Why Investors Love Wonder

Why Investors Love Wonder

CNBC

CNBC spends about ten minutes on Wonder, Marc Lore's food-tech startup that has raised $3 billion since 2018 to rethink dining with automation and customization. Investors are sold, but it's still unclear whether diners will be.

Your Local AI Is Not as Private as You Think

Kai

Running models on your own machine keeps prompts away from cloud providers, but Kai shows where the real risks hide: poisoned weights, chat templates and exposed Ollama ports. His five fixes are worth a quick check before you give a local agent shell access or your .env files.

The ElevenLabs Situation Is Crazy

Chris Williamson

Chris Williamson found a popular ElevenLabs voice that sounds a lot like him, down to his Northeast England accent. It's a good look at what voice consent means once anyone can make a stock voice say anything for a few dollars.

Speech Recognition Without the Internet Now Fits on a $10 Chip (Whistle)

Speech Recognition Without the Internet Now Fits on a $10 Chip (Whistle)

Better Stack

Better Stack fits Whistle, a 16.9 MB speech-to-text model, onto a $10 ESP32-S3, where it runs with no Wi-Fi and no cloud. They walk through what they cut to make it fit and how they brought processing time from 24 seconds to about 10, so it's not instant. The full project is on GitHub if you want to build one.

Jev Can SERIOUSLY Supercharge Your AI Second Brain (Here's How)

Cole Medin

Cole shows how Jev takes over the small, constant calls in his second brain, like which emails need a reply and which ideas he's already seen, faster and cheaper than an LLM. He's also upfront about where it still falls short, which is the part we found most useful.

I built a Blockbuster

Pre Internet

A scratch-built Blockbuster with 1,200 tiny VHS tapes, plus interviews with people who actually worked there. It's half model build, half memory project, and the care in both halves is what makes it worth the 25 minutes.

Adam Savage Stunned by 3D Printed Rubber!

Adam Savage’s Tested

Adam and Norm put Formlabs' Flexible 80A resin through a drop test, a wall-thickness test and a Gothic cathedral print, then visit the materials lab where it was developed. The chemistry segment and the post-processing tips make it worth watching start to finish.

This Game Was Built Only With AI in 11 Weeks

Stefan 3D AI

Stefan plays through games his viewers built with AI, from a cozy fishing game Claude made through Blender MCP to a 1920s fishing-and-smuggling game one dev has been building with Claude for 11 weeks. The good part is he asks each builder how they did it and what it cost, then says what he'd do differently.
