Arduino Nano ESP32 becomes an ultra-low-powered, pocket-sized Linux PC

While many users get them confused, microcontroller development boards and single-board computers are very different things. Single-board computers can run full operating systems, like your desktop PC or laptop does. Microcontroller development boards, like those from Arduino, are usually limited to simpler firmware. But as microcontrollers become more powerful, the line gets blurrier. To prove […]

DIY EMF detector scans for ghosts and appliances

Electromagnetic field (EMF) detectors are popular pieces of ghost hunting equipment. The idea is that paranormal apparitions emit a noticeable EMF that proves their existence. But in reality, those EMFs come from electric and electronic devices. And an EMF from your microwave may, for example, interfere with your Wi-Fi network and cause performance problems. So […]

This smart diaper knows when it is ready to be changed

The traditional method for changing a diaper starts when someone smells or feels the that the diaper has been soiled, and while it isn’t the greatest process, removing the soiled diaper as soon as possible is important for avoiding rashes and infections. Justin Lutz has created an intelligent solution to this situation by designing a small device […]

A DIY tube furnace for creating ICs

Modern integrated circuit (IC) chips can have transistors as small as two nanometers, which is only about 10 silicon atoms laid end-to-end. At that scale, fabrication looks more like chemistry than any kind of physical manipulation — a machinist isn’t carving tiny transistors into silicon wafers. For many types semiconductors, the fabrication process requires a […]

Mysoltrk is a low-cost solar panel tracking system

While a solar panel installed on the top of a roof, lamp post, or the side of a building will produce power, it is nowhere near optimal for achieving the maximum efficiency possible. To get better results, panels are often mounted to pivots and linear actuators/servo motors that continually move to always face the sun. […]

Turning a Barbie dreamhouse into a screamhouse with the Arduino UNO R4

With its bright color scheme and generally upbeat tone, the recently released Barbie movie evokes many of the same feelings as the toy brand. In keeping with this idea, Jaimie and Jay of the Wicked Makers YouTube channel decided to take it in the opposite direction by transforming a Barbie dollhouse into a haunted mansion for Halloween — complete […]

Experiments in PID control with an Arduino UNO R4 Minima-powered robot

In robotics and several other disciplines, PID (proportional-integral-derivative) control is a way for systems with closed-loop feedback to adjust themselves according to sensor data without overshooting the target. Drones, for example, use PID control to remain stable without wild oscillations caused by over-correction. But implementing PID control can feel overwhelming, so Adam Soileau from element14 […]

How to build a low-resolution thermal camera at a low cost using Arduino

Thermal cameras are very useful tools, because they let us see heat that would normally be invisible to our eyes. Maybe you’re working on a custom PCB and want to see if any of the components generate excessive heat. Or maybe you’re concerned that your car’s exhaust headers don’t heat evenly and you want to […]
