IKEA’s Vindriktning air quality sensor. Because I just used a Raspberry Pi Pico W to put one of those on the internet.
Looking at [Wayback/Archive] bafkreiguunarmi7u6wqx52fweumduakxt6ddhm2a3gklv7nxpxsb5ma5nu@jpeg (750×1000), it only measures PM2.5, temperature and humidity but not CO2.

Hack your home: [Wayback/Archive] Chris Bensen on Twitter: “Web server on @arduino connected to a MOSFET, soldered 3 wires to garage door opener and bada bing bada boom, I can open the garage door from any web browser. Next up, Home Kit integration, Arduino sensors for door state, clean it up, then blog it if there is interest?”
Via [Wayback/Archive] Chris Bensen on Twitter: “I made some progress on my garage door opener project this weekend and ordered parts for next phase. I’m looking for a cool name, any suggestions? Also I looked into the business of garage doors and why its so f-ed up. It’s all a monopoly and outsourced! Go figure.”

Naming of the Golmar series is confusing: Stadia, Tekna, Szena.

[Wayback/Archive] Moving things – YouTube is a short remix of the YouTube short video [Wayback/Archive] Based on your ideas! What else shall I design? – YouTube based on an idea from [Wayback/Archive] cdaylward (Charles D. Aylward) · GitHub.
Basically it is the opposite of the Eye-Fi: you op a micro–SD card in the board, then mount the board on an ESP32 one with Wi-Fi, power up the combo, then can you can access the files via your Wi-Fi network.
This makes it a lot easier to transfer files to for instance a 3D printer. For some of these printers in order to refresh the content, you have to pull out then re-insert the microSD/adapter/ESP32-board contraption.
Hopefully by now the tutorial mentioned at the end of the video has been published online.
Images grabbed from the above video:

Only do this when your G3 is broken beyond repair!
This particular example shows how to shoe-horn an Apple Silicon based Mac Mini into a the very first incarnation of an iMac: a classic iMac G3 case restoring both plastic, and using 3D printed mounts to ease assembly/disassembly.
Still cool as it is flexible so also allows for other Mac hardware like a Mac Studio.
The screen is a 14 inch 16:10 screen which is very expensive over here:

Likely a 4:3 OLED screen has less visible bezels.

The display quality of [Wayback/Archive] Reflection Frame is nice, but the there was no public API at the time of writing, so I wonder if there is now.
