arduino.cc 2022-08-04 20:58 This air cleaner activates when it hears shop tools running Air cleaners are indispensable appliances in shop environments. Fine sawdust in the air can, for example, cause a variety of respiratory ailments in woodworkers. Even if the tool itself has a vacuum collection system,...
arduino.cc 2022-08-03 21:14 Adding a battery gauge to a Citroën C-Zero electric car The Citroën C-Zero is an electric city card sold in the European market. It is a rebadged Mitsubishi i-MiEV, which is based on the Mitsubishi i kei car platform. Kei cars, in Japan, are a special class that receive...
arduino.cc 2022-08-03 08:15 Reading typewriter key presses with an Arduino There was a period in the late ‘70s and into the ‘80s when typewriter manufacturers tried to keep up with the tide of the digital age. Personal computers were hitting prices that middle-class families could justify...
arduino.cc 2022-08-02 05:36 Arduino-controlled robot solves Rubik’s Cubes in a couple seconds Rubik’s Cubes have been sold in stores for more than 40 years now, but most of us still can’t solve them. Others take the puzzles very seriously, competing in many speed-solving competitions around the world. The...
arduino.cc 2022-08-02 05:27 DIY SawStop saves fingers from shop mishaps Many power tools have the potential to cause serious harm, but few are as dangerous as table saws. But table saws are also indispensable for woodworking, which means that people are willing to risk their fingers to use...
arduino.cc 2022-07-28 03:50 Centimeter-scale lawn mower positioning without GPS RTK 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....
arduino.cc 2022-07-28 03:42 This walking machine can mosey in any direction Wheeled vehicles are so common because they’re efficient. If a vehicle will drive on a relatively smooth and flat surface, wheels are the most efficient option. But on rough terrain, wheels don’t always cut it. For...
arduino.cc 2022-07-27 20:01 This system detects leaks by listening to water flowing through pipes Damaged, leaking pipes are not only a nuisance to clean up after, but they can also create major inefficiencies within water delivery systems, leading to a loss in both the water itself and the electricity required to...
arduino.cc 2022-07-26 03:26 A DIY thermally actuated deformable mirror 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...
arduino.cc 2022-07-26 00:58 Reviving a vintage secondary split-flap clock with Arduino 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...
arduino.cc 2022-07-25 20:24 Now you can make shawarma at your desk If you’ve ever been lucky enough to visit a country in the Middle East or around the Mediterranean Sea, then you’ve probably seen street food vendors cutting slices off of a big ol’ hunk of slowly rotating meat....
arduino.cc 2022-07-22 23:33 Converting a Commodore PET into a USB docking station The Commodore 64 is one of the most iconic computers of all time and it is Commodore’s best known model. But Commodore made many other well-loved models, including the VIC-20, the Amiga, and the PET. The Commodore...
arduino.cc 2022-07-22 07:50 Industrial IoT anomaly detection on microcontrollers Consumer IoT (Internet of Things) devices provide convenience and the consequences of a failure are minimal. But industrial IoT (IIoT) devices monitor complex and expensive machinery. When that machinery fails, it can...
