The cat's out of the bag! My latest book, "The Secret Life of Circuits", is available in early access:

https://lcamtuf.coredump.cx/blog/secret/

It's the reference I wish I had when I was starting out. Electrons to embedded systems, 290+ color illustrations and 420+ pages of well-explained theory.

The Secret Life of Circuits

Many of you follow this blog because of the regular features about electronic circuit design.

I wrote up a guide on how to build a set of walkie talkies with esp-now and Arduino. Case design was inspired by some Barbie-themed toy walkie talkies that a friend of mine had when we were little kids

ESP-NOW Walkie Talkies

Ditch the smart phone and communicate with your buddy by building this set of walkie talkies! A Feather ESP32-S3 Reverse TFT runs Arduino code that uses the ESP-NOW protocol to send and receive I2S audio packets. The w.FL antenna adds extra range to communicate at longer distances indoors or outdoors.

Ladies and gentlemen, we have a working BambuLabs #CircuitPython library, making it easy to query info about your printer. This way people can build UIs on top of the easy to get data.
