James Bruton builds a real Zelda Stabilizer Zonai Device
Reading Time: 2 minutesThe central gimmick of the new Legend of Zelda: Tears of the Kingdom game is the construction system, which is a lot of fun. You can fuse simple objects to build structures, but you can also add Zonai Devices to increase their functionality. One of those devices is the Stabilizer, which forces any attached…

Arduino Nano ESP32 becomes an ultra-low-powered, pocket-sized Linux PC
Reading Time: 2 minutesWhile 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…

DIY EMF detector scans for ghosts and appliances
Reading Time: 2 minutesElectromagnetic 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 you microwave may, for example, interfere with your Wi-Fi network and cause…

This smart diaper knows when it is ready to be changed
Reading Time: 2 minutesThe 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 DIY tube furnace for creating ICs
Reading Time: 2 minutesModern 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…

Mysoltrk is a low-cost solar panel tracking system
Reading Time: 2 minutesWhile 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…

Turning a Barbie dreamhouse into a screamhouse with the Arduino UNO R4
Reading Time: 2 minutesWith 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…

Jumperless breadboard makes prototyping a breeze
Reading Time: 2 minutesMost makers start their initial electronics prototypes on a breadboard, which is great for quickly setting up temporary circuits. But forming the connections requires jumper wires and even a basic project quickly becomes a rats’ nest of wiring that is difficult to manage. Tracking down issues within that tangle of wires is…

Custom vacuum controller facilitates the construction of vacuum tubes
Reading Time: 2 minutesVacuum tubes used to be the building blocks of computation and the drivers of screaming guitar amplifiers, but they’re rare today — so rare that there are virtually no manufacturers producing new units. If you shop for vacuum tubes, most of what you’ll find is either used or NOS (new old stock).…

Adding a turbo readout to a vintage PC case
Reading Time: 2 minutesIf you are young, you may not remember the turbo buttons of the 1990s. These existed for backwards-compatibility with older games and software that wouldn’t run properly at the blazing-fast processor clock speeds of the time. The turbo button simply told the CPU to run at a slower clock speed that would…

This Nicla Vision-based fire detector was trained entirely on synthetic data
Reading Time: 2 minutesDue to an ever-warming planet thanks to climate change and greatly increasing wildfire chances because of prolonged droughts, being able to quickly detect when a fire has broken out is vital for responding while it’s still in a containable stage. But one major hurdle to collecting machine learning model datasets on these…

Magic office gadget encourages coworkers to solve problems
Reading Time: 2 minutesWhether it’s budget issues, lack of time management, or simply not having any ideas for solving the issue at-hand, dealing with coworkers who bring up these problems is a pet-peeve of element14 Presents host Mark Donners. In response, he built a simple wall-mounted ornament consisting of a series of magic wands that prods coworkers to…

New backscatter technology promises cost-effective reliability
Reading Time: 2 minutesTraditional bi-directional wireless communication requires both a receiver and a transmitter at either end. Your laptop, for example, needs to receive a signal from your Wi-Fi router, but it also needs to transmit a signal back to that router. That transmission requires power proportional to the strength of the signal, which is…

A snore-no-more device designed to help those with sleep apnea
Reading Time: 2 minutesDespite snoring itself being a relatively harmless condition, those who do snore while asleep can also be suffering from sleep apnea — a potentially serious disorder which causes the airway to repeatedly close and block oxygen from getting to the lungs. As an effort to alert those who might be unaware they…

Building a dedicated 3D printer hot end controller with the Arduino UNO R4 WiFi
Reading Time: 2 minutes3D printers need to set their hot ends to a very specific temperatures suited to the filament material and keep them at those temperatures throughout the printing process. Most use PID (Proportional-Integral-Derivative) control for that purpose, which modulates power according to an algorithm that prioritizes stability and prevents feedback oscillations. But what…

Small PoV display uses CD drive motor for high-speed rotation
Reading Time: 2 minutesThe human brain and eyes are imperfect, so your visual perception has a limited “frame rate.” That is somewhere between 30 and 60 frames per second (fps). Most films are 24fps, which is part of the reason they don’t quite look like real life. Once you reach the upper limits of the human visual…

Channel your inner Bruce Lee with this DIY reflex coach
Reading Time: 2 minutesVideo games are popular because they provide a clear and reliable loop of effort and reward. If you smash the baddie, you get experience; get enough experience and you level up. But real life isn’t like that and there is little direct correlation between effort and reward, which is dissatisfying. Gamification techniques…
