This wrapping machine makes wire harness creation a breeze
Reading Time: 2 minutesArduino Team — September 5th, 2022 Many products require the use of wire harnesses, which are essentially bundles of cabling that connect one subsystem to another, such as a car engine’s sensors to the ECU. DIY projects can also find themselves needing one, but having to manage the wiring without tangles or…

New display technology features magnetic pixels
Reading Time: 2 minutesArduino Team — August 24th, 2022 Display technology, from cathode-ray tubes to LCD screens, exists to convey information to humans visually and it does that very well. But the lack of physical presence makes visual displays useless for almost everything else. The blind can’t feel pixels and computers need resource-intensive algorithms to…

Building an electronic pantograph with Hall effect sensors
Reading Time: 2 minutesArduino Team — August 22nd, 2022 A pantograph is a machine that lets an artist copy an image by tracing the original. Traditional mechanical pantographs use a complex linkage system to move the output pen relative to the stylus. While 1:1 pantographs do serve a purpose, the real value comes from a…

Building the worst digital camera ever
Reading Time: 2 minutesArduino Team — August 16th, 2022 Digital cameras work by letting light through a lens onto a sensor composed of photosites, each with a photodiode that outputs a signal relative to the brightness of the light. Modern digital camera sensors have millions of photosites, each of which contains a microscopic photodiode. The…

Building a DIY laser modem
Reading Time: 2 minutesArduino Team — August 8th, 2022 All digital communication ultimately comes down to transmitting ones and zeroes, but there are many ways to achieve that. One can encode that binary data as modulation in a radio signal or simply pulse electricity through a wire. But one of the most interesting methods is…

This high-precision AC meter handles inductive loads
Reading Time: 2 minutesArduino Team — August 5th, 2022 AC (alternating current) meters are useful tools for measuring power draw. One might use an AC meter to monitor the power consumption of their devices and appliances with the goal of lowering their energy bill. Makers in particular can benefit from AC meters to learn about…

Centimeter-scale lawn mower positioning without GPS RTK
Reading Time: 2 minutesArduino Team — July 27th, 2022 GPS is perfect for navigating roads, because that doesn’t require much precision. But GPS is only accurate to several meters, which means that it is unsuitable for applications that require more precise positioning. GPS RTK (real-time kinematic) systems can achieve much greater accuracy, but they are…

A DIY thermally actuated deformable mirror
Reading Time: 2 minutesArduino Team — July 25th, 2022 In typical applications, the optimal mirror is as flat as possible. The flatter the mirror, the less optical distortion it imparts onto the reflected “image.” Distortion isn’t often desirable, so precision mirror manufacturers take great pains to manufacture ultra-flat mirrors. But distortion is sometimes a good…

Reviving a vintage secondary split-flap clock with Arduino
Reading Time: 2 minutesArduino Team — July 25th, 2022 In the world of computing, many interfaces utilize a primary/secondary model of asymmetric communication, in which a primary host device controls one or more secondary client devices. This model is, for example, common among PATA and SATA hard drive arrangements. It is also common in clock…

A PDA-style mini pocket computer
Reading Time: 2 minutesArduino Team — July 13th, 2022 For a time in the late 1990s and early 2000s, PDAs (personal digital assistants) were quite popular. But smartphones made PDAs obsolete, as even early models had far more functionality. Many of today’s microcontrollers have performance similar to early PDAs and Volos took advantage of that…

This small device helps test thousands of old PS/2 keyboards
Reading Time: 2 minutesArduino Team — July 12th, 2022 Some vintage computer keyboards, especially units like the IBM Model M, are still quite desirable. Usually they’re popular among mechanical keyboard or retro computing enthusiasts who want period-correct hardware. YouTuber Midwest Cyberpunk had thousands of these old keyboards and needed a way to test them. So…

This small Space Invaders game runs on an Arduino Nano with a salvaged CRT display
Reading Time: 2 minutesArduino Team — July 6th, 2022 Rob Cai over on Instructables has created his own version of the classic video game Space Invaders using an Arduino Nano. However, unlike most other projects that would typically incorporate some kind of LCD or OLED screen, he chose to use a small black and white cathode ray tube (CRT)…

This RGB wedding dress mimics Princess Aurora’s from Sleeping Beauty
Reading Time: 2 minutesArduino Team — June 17th, 2022 Inspired by his Christmas tree’s RGB lights, Brett Haddoak had the idea to turn his now-wife Rachelle’s wedding dress into something out of the classic children’s movie Sleeping Beauty by embedding a series of RGB LED strips that would elegantly illuminate it just like Princess Aurora’s. At first, Haddoak chose…

Graffiti robot paints like a human
Reading Time: 2 minutesArduino Team — June 9th, 2022 Robots are capable of far more precise and accurate motion than humans are. That is great when you want a robot to assemble a PCB or perform heart surgery. But it’s a problem when you want robots do something creative — they’re just too perfect. The…
