A bare bones scheduler isn't that hard either.

Small embedded projects utilizing Teensy or Arduino don't need Rust per se. A program encompassing a a few thousand lines can be made reliably in C by a single person. Rust is only needed for code bases consisting of tens to thousands up to...

A piece? Or per number of pieces?

My only issue with Zephyr is that it's written in C. I believe all new OSs should be written in Rust.

You might want to look at the Snooze library. It is included with Teensyduino.

Try to replace the FreeRTOS with a context switcher, like the one suggested by ARM.

Has anyone seen this? I think it's pretty nifty. But it's also quite expensive. Can anyone recommend something similar but cheaper?

Debugging isn't even possible at the moment (AFAIK). I'm only using the USB serial debug output to see what's happening.

The TeensyThreads API mentions sleeping for a certain amount of time, but how about sleeping until an interrupt wakes up the CPU? Does the library allow for that? This is obviously relevant for battery powered applications where you want the CPU...

The idea is to completely replace the power adapter and the 7805 regulator with the USB breakout.

I'm planning to use something like this to power my future boards.

With a Voltcraft Energy Check 3000.

My Teensy alarm clock is powered by a (regulated) wall plug adapter which outputs 7.5V and a 7805 voltage regulator converts this into the 5V needed to power the device. It uses about 4W continuously. However, when I power the board through an...
