I've been on a mission to unify all my smart devices under one app, and as someone who's running most of his smart devices with ESP32s, the toaster seemed like the next logical step. After all, all I ...

Like many nerds, I have an interest in cryptography rooted in the wartime exploits of codebreaker and Ur-computer scientist Alan Turing. So I’ve followed with interest IEEE Spectrum’s reporting on the ...

At CircuitDigest, we've been creating and sharing Internet of Things (IoT) projects with our community for a long time. A crucial part of these projects is enabling communication between IoT devices ...

1. Joints - The Foundation of Movement Joints are the moving links in a robotic arm. They let the arm bend, rotate, or change ...

We’re all used to Bluetooth chips coming in QFN and BGA formats, at a minimum of 30-40 pins, sometimes even a hundred. What ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you ...

Espresso machine test 2025: 7 home setups compared – design, tech & daily grind. Which one’s the best espresso machine for ...

Genetic circuit engineering is the synthesis of unnatural DNA segments encoding protein or RNA molecules that control each other’s levels. Genetic circuit engineering is the bottom-up, local approach ...
