Un ami m'a donné un petit appareil #LoRa ,je l'ai mis sur le balcon pour créer un noeud et étendre le réseau mesh \^_^/

If you don't own the hardware, you emulate it.

The ESP32 QEMU port appears to work, though it's slow.

You can run #Zephyr applications on QEMU, which is great for early development, debugging, and #CICD workflows. Check out my tutorial for using Espressif’s QEMU fork for emulating #ESP32 applications made with Zephyr: https://shawnhymel.com/2807/how-to-run-an-esp32-zephyr-application-on-espressifs-qemu/ #embedded #programming

I’m working on an open source autograder for my upcoming #ESP32 course. I’m not a backend coder, so I’ve learned a lot (with no small amount of help from AI tools). The plan is to target simulation environments for #embedded systems (e.g. qemu), but it should work for a variety of build/runtime environments. #programming #IoT #education

SNS-GESTURE is hand gesture recognizing module with I2C interface which easily can be interfaced to Arduino, PICO or ESP32 with MicroPython https://olimex.wordpress.com/2025/06/16/sns-gesture-is-i2c-hand-gesture-recognizer-module-which-you-can-easily-interface-to-your-next-arduino-or-micropython-project/ #esp32 #pico #arduino #gesture #regonize #i2c #module
This module will help you to add fancy interface to your next project and to navigate without keyboard and mouse.

Please excuse my messy desk. This is my prototype of a battery powered and solar charged ESP32 WS2813 nightlight.

At the moment it is turning on the light when motion is detected, I have to add a light sensor. Then I would be able to turn on the light only when it's dark.

I'll keep you updated, a 3D printed case should be able to fit all those stuff.
