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.”

[Wayback/Archive] GitHub – computerequipmentgroup/equip-1: Compact DV recorder · GitHub
Compact DV recorder. Connects to any FireWire camcorder and saves footage directly to microSD. No laptop required.
Supports MiniDV, DVCAM, DVCPRO, Digital8, and HDV. Controls the tape deck on supported cameras, so you can digitize an entire tape automatically. Pressing record on the camera triggers capture on the Equip-1.
Built around the Radxa ROCK 2F and our custom Firehat — a FireWire HAT with a VIA VT6315N controller connected via PCIe over FPC.
The Firehat is also available standalone. It works as a HAT for the ROCK 2F, Pi 5 and other SBCs.

[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:

Lot’s of power supplies on [Wayback/Archive] MikroTik Routers and Wireless – Products, most (except the internal ones) I listed below grouped by output voltage and amperage (and wattage which I rounded down).
I didn’t realise there were so many and that there basically is no consistent naming scheme.
