I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless control to Arduino or ESP8266 projects. In this video, I’ll walk you through ...

Modern technology builds on abstractions. Most application programmers today don’t know what a non-maskable interrupt is, nor should they have to. Even fewer understand register coloring or ...

It’s always nice to simulate a project before soldering a board together. Tools like QUCS run locally and work quite well for ...

I needed to verify that a newly installed LoRaWAN gateway was working correctly, so I built a simple and portable testing ...

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

We use WhatsApp almost every day so much that it has become an unavoidable part of our routine. From a simple “good morning” ...

This DIY 6-DOF robot arm project details a two-year build cycle using 3D printed parts, custom electronics, and over 5,000 ...
