Whether you’re interested in enhancing model trains, or simply want to hear more about integrating LED matrix displays into your next project, here you have some information you might find interesting. “I have used LED matrix displays for a number of different projects over the last few years. These 8×8 LED units have a controller that…
After many hours studying Arduino programming and thanks to the support of the Arduino Forum.cc community, the maker MBcreates was able to build his first Arduino project: a digital air pressure regulator. “Simple is often better. So I grab an old blowgun and used this a valve. The Arduino Digital Air Pressure Regulator uses a…
Asier Marzo, Adrian Barnes, and Bruce W. Drinkwater have developed a 3D-printed, Arduino Nano-controlled acoustic levitator. Thanks to this device you can levitate tiny drops of liquid, small solids, or insects in mid-air. Acoustic levitation has been explored in hundreds of studies for applications in pharmaceuticals, biology or biomaterials. It holds the promise of supporting innovative and ground-breaking…
Recently, low-cost microcontrollers like the Arduino have opened new doors for makers looking to do fun and interesting things with their vehicles. If you’ve ever had to park your car in a small garage or cramped space, you probably understand the frustration of not knowing how much room to leave behind and in front of your car….
Sometimes you want your creation to look great. That was the case here, as this electromechanical clock integrates several different types of metal along with a chain drive into something that’s as much a work of art as it is a practical timekeeping tool. This clock was designed, machined and assembled, every piece from scratch…
If you want to truly impress your child or your grandkids, and perhaps entertain yourself at the same time, there are many things you could do. Building a 1/4-size railroad, however, has to be close to the top of the list. The entire project was inspired by a 1965 Popular Mechanics article, and includes a…
POV Displays move through the air at a high enough speed to trick your eyes into thinking that a sequence of flashing lights is actually a solid image. Though interesting enough in two dimensions, LED Instructable maker “Gelstronic” decided to add more depth to his display, stacking 12 LED-enabled circuit boards in a helical pattern. PropHelix…
If you need to trigger a flash but you don’t find the satisfying app for your scope, you could do what Josh Beckwith did, making it from yourself. It’s a simple project, but it could be helpful for everyone with less experience with Arduino. You’ll need: Hardware – Strobe – Arduino Nano – NPN Transistor…
Using an Arduino Micro for control, the instructables user Joebarteam came up with a way to biometrically secure his garage. What could be better than using your fingerprint to unlock your garage? To this end, Joe’ came up with a system that unlocks his door using a fingerprint scanner, and a bistable relay to disable communication between…
Maker joesinstructables created a versatile, slithering system, which he calls the ‘Lake Erie Mamba.’ He put a dozen Arduino Mega-controlled servos together in a reptile configuration to allow the robot to move via serpentine motion (like a normal snake), rectilinear motion (like a worm), or sidewinding (which snakes use in shifting terrain). It can also twist itself into a…
Using an Arduino board and motor controllers, maybe you can solve the pre-departure stress. The backpack in question is wheeled around by two motors on mounts made out of paint sticks. The drive train of this robot consists of two powered wheels, and the two original wheels of the backpack. The only change that needs…
A control unit for the garden sprinkler that can be controlled via web and smartphone thanks to Arduino Yún. With summer approaching, our plants and our gardens need some regular watering in order to stay lush and green as we like them. It’s not easy to always remember to water plants and gardens…
