Build for monitoring, buy for safety.

It's why DIY smart home projects suddenly got cheap (and actually doable) ...

Abstract: This article presents the design, simulation, and construction of a low-power three-phase inverter using sinusoidal pulse-width modulation (SPWM), implemented with a low-cost microcontroller ...

It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for analog circuits, but can fall short with programmable logic. Tools like ...

When I wrote about a DIY ESP32-S3 internet radio last week, "raspbeguy" commented he'd rather choose an ESP32-based DIY DAB+ ...

In a move that’s no doubt going to upset and confuse many, Espressif has released its newest microcontroller — the ESP32-S31.

AI coding replaces edit and debug with instruct and guide. Terminal plus AI replaces traditional development environments. IDEs are reduced to build and deployment tools only. My little dog Pixel does ...

- Many water sensors are active LOW or active HIGH depending on wiring. Set SENSOR_ACTIVE_STATE accordingly. - Built for Arduino core for ESP32 (use recent esp32 board package).

Abstract: In this paper, we describe a smart fitness tracker that helps count exercises like push-ups, squats, and jumps automatically. The system uses an ESP32 controller and an MPU6050 (IMU sensor) ...
