Whoopsies forgot to post abt these gjdbgj I have created Peach Blossom and Smilk playlists hooray

[allie-leth]

My worker firmware works! It flashed itself over, now just to add some roll back, security, and validation features. But effectively this means I never have to plug in another ESP32 to send them firmware. I can just tell them to post to MQTT from the worker firmware for logging and post the firmware binary to my local file server. This makes my life so much easier while building out this mesh of meshes multi-protocol com lib. Hell yeahhh

Why does digital elecronics is important for engineering?

Digital electronics is super important in engineering for a bunch of reasons—it's pretty much the backbone of modern technology. Digital electronics powers everything from smartphones and computers to cars and medical devices. Engineers across disciplines need to understand it to design, troubleshoot, or innovate with modern systems.

GET CIRCUIT DESIGNING VIDEO TUTORIAL 👈.

Digital tech allows for very large-scale integration (VLSI), meaning engineers can cram millions of logic gates into a single chip (like microprocessors or memory). It enables powerful, compact, and cost-effective designs.
