Pine64 and Radxa's new Pi CM4-compatible boards

Camera Pi – DSLR Camera with Embedded Computer
I’ve had the idea of embedding a computer DSLR camera for a couple of years now, but for whatever reason I never got around to implementing it, mostly due to the cost of small single board computers.

Receive push notifications from your rice cooker
I have a lovely, and reasonably priced, Mini Panda Rice Cooker. It does not have any SmartHome features. You put in water and rice, press a button, it cooks rice. Nice!
