An awesome new open source long-range RC transmitter
Reading Time: 2 minutesDSM (digital spectrum modulation) is a relatively new radio control technology that is ideal for long-range applications. It uses two methods, FHSS (frequency hopping spread spectrum) and DSSS (direct sequence spread spectrum), to transmit data, with the latter being especially resilient to interference and therefore suitable for transmission over long distances. If…

New authentication technology measures light reflected by hands
Reading Time: 2 minutesBiometric identification and authentication is big business. As an example, consider Apple’s Face ID technology, which has made strong smartphone security both user friendly and readily available. But Face ID requires substantial hardware and computational power to work, which makes it ill-suited for applications where cost is a major concern. To fill…

Let your coworkers know how you feel with this stress level indicator
Reading Time: 2 minutesAsking your boss for a raise when they are in a bad mood is not ideal, and this is what prompted Mark from element14 Presents to create a stress level indicating project that could show this mood to everyone else so they could avoid this awkward situation. Mark started this project by laser cutting…

The CWvox is a simple device that converts voice commands into Morse code keying
Reading Time: 2 minutesWhile most of us associate Morse code with old-timey telegraphs, it is still in use today. The benefits now are the same as they were a hundred and fifty years ago: it is an incredibly resilient way to encode information that works with a variety of different transmission methods. But what if…

Lumos finally enables wearable spectroscopy research
Reading Time: 2 minutesSpectroscopy is a field of study that utilizes the measurement of electromagnetic radiation (often visible light) as it reflects off of or passes through a substance. It can, for instance, help researchers determine the composition of a material, as that composition influences how the material reflects light. Spectroscopy is also used in…

3D-printed digital clock contains 24 analog clocks
Reading Time: 2 minutesClocks are fantastic means of creative expression, as they serve a practical purpose and therefore have a reason to exist, but aren’t limited to pure functionality. As such, we see many interesting clock designs. But ihart’s 3D-printed digital clock made from 24 individual analog clocks takes the proverbial cake. When observed from…

Update your ESP32 boards over-the-air (OTA) with Arduino Cloud
Reading Time: 3 minutesThe Arduino Cloud is Arduino’s integrated platform to develop, deploy, monitor, and control IoT devices with minimal effort. It enables makers, IoT enthusiasts, and professionals to build easily connected projects based on a wide range of hardware including not only Arduino boards, but also ESP32 and ESP8266 boards. Arduino is committed to…

Robot collects ping pong balls after matches
Reading Time: 2 minutesIf you frequent driving ranges, you’ve probably seen a machine (often attached to the front of an armored golf cart) designed to pick up golf balls. Because a driving range can easily fill up with thousands of golf balls an hour, such machines are necessary. After noticing that nobody wanted to pick…

Sci-fi film prop doubles as a DJ helmet
Reading Time: 2 minutesTake a moment to think about some of your favorite electronic music DJs. How many of them wear some sort of a helmet or mask? You can probably think of at least a few. For whatever reason, DJs like their privacy. Daniel Aagentah was tasked with making a sci-fi film prop helmet…

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…

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…

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…

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…
