Arduino speaks without any special hardware
Reading Time: 2 minutesWe see many Arduino projects that feature audio output, but they tend to require a substantial amount of additional hardware. Audio files take up a lot of storage space, so they require something like an SD card adapter. Audio signals are analog, so they require a DAC (digital-to-analog converter) to get good…

Helping robot dogs feel through their paws
Reading Time: 2 minutesYour dog has nerve endings covering its entire body, giving it a sense of touch. It can feel the ground through its paws and use that information to gain better traction or detect harmful terrain. For robots to perform as well as their biological counterparts, they need a similar level of sensory…

DIY parachute system saves drones and rockets
Reading Time: 2 minutesToday’s consumer and professional drones are very stable. They’re easy to pilot and we’re past the era of rampant out-of-control drone crashes. But drones can still fail and benefit from a system that lets them return safely to the ground without damage. That is also true for hobby rockets, which still have…

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…

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…
