Arduino resurrects a washing machine that failed for silly reasons
Reading Time: 2 minutesThe maker movement often focuses on creation, but we should never overlook repair. In a consumer market increasingly moving towards planned obsolescence, manufacturers often fail to devote any resources towards the repair of their products. In many cases, replacement parts are unavailable or prohibitively expensive. But the maker skill set can provide…

Walk-Bot helps people with visual impairments navigate safely
Reading Time: 2 minutesIt is no secret that visual impairments — even those that don’t result in complete blindness — make it very difficult for people to live their lives. White canes can help people get around, but they require physical contact. Seeing eye dogs provide very valuable assistance, but they’re expensive and need care…

The 2022 Arduino Open Source Report is out
Reading Time: 2 minutesIn our last annual report we described 2021 as one of the busiest and most productive years in Arduino history in terms of open source development (if you missed that report, go read it now as it contains so many nice things). Well, we didn’t rest in 2022 either! The Arduino team…

Get creative with Raspberry Pi Pico
Reading Time: 2 minutesFiber OpticMatrix Display Using LEDs such as NeoPixels is a pretty easy thing to do – we’ve covered them extensively in issues 122 and 123 with light-up vacuum cleaners and Christmas tree lights. This project (which we covered in issue 118) goes further, using optic fibres connected to an LED board to…

This DIY Apple Pencil writes with gestures
Reading Time: 2 minutesReleased in 2015, the Apple Pencil is a technology-packed stylus that allows users to write on iPad screens with variations in pressure and angle — all while communicating with very low latencies. Nekhil Ravi and Shebin Jose Jacob of Coders Café were inspired by this piece of handheld tech to come up with their own…

A 3D-printable, Arduino-controlled star tracker great for astrophotography
Reading Time: 2 minutesMost modern digital cameras are perfectly capable of capturing photos of the stars. But many of them have trouble collecting the small amount of light available in a short amount of time, which means that you need to leave the shutter open for 30 seconds or more to get a decent exposure.…

DIY focus stacking device aids in macro photography
Reading Time: 2 minutesIf you’re ever tried to capture some macro photographs (very close-up pictures), you’ve probably noticed that it is difficult to get proper focus. Because the depth-of-field (DoF) for macro lenses is so small, you can only keep a narrow range of distance in focus at any given time — everything else is…

Make sound with Pico
Reading Time: 3 minutesPico Portal Music Box Even after 15 years, Portal’s Still Alive song is still well remembered and this project will make sure you never forget it. Pico can actually play MP3 files, and maker thisoldgeek wanted to give it a more antique music box vibe, so he created one in the style…

Multi-function device displays PC data and news
Reading Time: 2 minutesWhile the typical computer user doesn’t need to worry about it, those of us who overclock our computers or run them hard like to know how they’re performing. If, for example, you overclock your CPU, then you probably want to keep an eye on its temperature to ensure that it doesn’t exceed…

The Arduino Launch Control System is a model rocket enthusiast’s dream
Reading Time: 2 minutesConventional hobby model rockets get their thrust from disposable motors containing an explosive propellant, like black powder. But unlike the gun powder in a firearm’s cartridge that uses a concussion-activated primer to ignite, model rocket enthusiasts ignite their motors using an electric arc. Simple launch controllers consist of little more than a…

This pen plotter gets nervous when observed
Reading Time: 2 minutesThe whole purpose of machine automation is to eliminate human needs and errors. A CNC machine doesn’t get tired, doesn’t need breaks, and performs a task exactly the same way every time. But what if that weren’t true? What if machines experienced human emotions and let it affect their work like we…

Substituting a flex sensor for an inexpensive light-dependent resistor
Reading Time: 2 minutesIn order to build wearables that react to movement, most people tend to reach for accelerometers, gyroscopes, and flex sensors. But due to their higher cost, one of teacher Gord Payne’s students wanted to create a low-cost alternative that could be easily sourced and integrated into projects. A typical glove with finger movement tracking normally…

RelayFi smart relay board review
Reading Time: 2 minutesThe four relays take up most of the board and handle conversion and control for four mains-powered devices. We highly suggest getting some kind of case for the board as there are solder points on the underside of the PCB. These relays are controlled via an optoisolator which does improve the safety…

This glove translates sign language using an array of sensors
Reading Time: 2 minutesFor people not familiar with American Sign Language (ASL), being able to recognize what certain hand motions and positions mean is a nearly impossible task. To make this process easier, Hackster.io user ayooluwa98 came up with the idea to integrate various motion, resistive, and touch sensors into a single glove that could convert these signals into…

This search and rescue robot creates 3D maps of disaster areas
Reading Time: 2 minutesIf you look at footage from the search and rescue efforts following any disaster, you’ll see that first responders have a very difficult time navigating through rubble to find people in need of emergency care. They also have to take extra precautions, as gas line ruptures and other hazards present dangers they…

What we achieved in 2022
Reading Time: 2 minutesFor 2022, I decided to make some goals and rough plans instead of stumbling into projects like I have in the past – and also promising to go a bit easier on myself if I didn’t achieve them all. Still stumbling One thing I’m always proud of is the work we do…

Code Pico with Thonny
Reading Time: 2 minutes2. Choose interpreter Thonny is normally used to write programs that run on the same computer you’re using Thonny on; to switch to writing programs on your Raspberry Pi Pico, you’ll need to choose a new Python interpreter. Look at the bottom-right of the Thonny window for the word ‘Python’ followed by…

This reverse geocache gift box only opens at specific GPS coordinates
Reading Time: 2 minutesGeocaching is a hobby that combines the fun of a scavenger hunt with modern GPS technology. One party will hide a small cache somewhere, then post the general location and the exact GPS coordinates for other parties to find. The goal is to use GPS navigation to find the hidden cache. Often,…

This Arduino Nano-based synthesizer can produce a wide range of intriguing sounds
Reading Time: 2 minutesSynthesizers have existed in their current form for several decades now. In essence, they generate simple waveforms that are then either added or subtracted together and modified through the use of filters, envelopes, and modulators to control pitch, volume, and several other characteristics. Due to their simplicity, many types of components can…
