By removing rare earths from the equation, these designs promise cleaner supply chains and more sustainable production.

A growing range of Arduino-based robotics resources now combine sensor integration, coding fundamentals, and practical hardware skills. From beginner micro servo tutorials to advanced sensor ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

For reliability, designers must create flex circuits that are neither too thick nor bend too much. • Every flex circuit has a neutral-bend axis. • Smaller circuit thickness reduces the risk of damage ...

In the first of a multi-part series on how to design a custom chip for under $1,000, our Analog Editor gets you started with a Magnificent 7 list of textbooks. TinyTapeout offers a course that ...

Well, this might just be a Hackaday first. Certainly not the circuit sculpture part, nor the wearable aspect, but the ...

A very cool (also warm!) property of the base-emitter junction of (most) small signal BJTs is the ΔVbe temperature-sensing ...

This repository contains Logisim circuit designs of basic computer architecture modules, including the control unit, arithmetic and logic unit (ALU), registers, and memory. To open and run the circuit ...

AICircuit is a comprehensive multi-level dataset and benchmark for developing and evaluating ML algorithms in analog and radio-frequency circuit design. AICircuit comprises seven commonly used basic ...

This chapter explains how we use transistors, how we bias them, so they generate working and useful circuits, and how we stabilize them as the temperature, currents, and applications vary. There are ...
