In theory, there’s isn’t much to building a CNC machine. Hook a bit to a motor and move the motor around with some lead screws and stepper motors. Easy. But, of course, the devil is in the details. [DAZ] made a nice-looking and inexpensive rig that probably isn’t the most precise CNC in the world, but it […]
600V intelligent power modules (IPMs) from Infineon make up the CIPOS Micro IPMs. They are qualified for harsh humid environments, passing 1000 hours of high voltage, high temperature and high humidity reverse bias (HV H3TRB) stress testing. This makes the energy-efficient IPM suitable for power appliance motor drives particularly in circulator hydronic pumps, drain pumps for washing machines, dishwashers,

This instructable describes how to make an ultrasonic “radar-style” display using an Arduino microcontroller, an ultrasonic sensor, and a small stepping motor. An optional sensor modification allows multiple objects to be detected with each ping. Construction is simple … all you need are two drills, a sharp knife, a pair of side-cutters , and a

[TheStaticTurtle] built a custom controller for automating his garage doors. He wanted to retain the original physical button and RF remote control interfaces while adding a more modern wireless control accessible from his internet connected devices. Upgrading an old system is often a convoluted process of trial and error, and he had to discard a couple

Multirotors, or drones as they’re popularly called, are so ubiquitous as to have become a $10 toy. They’re no less fun to fly for it though, and learning how they work is no less fascinating. It’s something [Science Buddies] has addressed in a series of videos examining them from first principles. They may be aimed at

We use electricity to move things with the help of motors and magnets all the time. But if you have enough voltage, you can move things with voltage alone. As [James] found out, though, it works best if your objects — ping pong balls, in his case — are conductive. He wanted to add a Van

We’ve gotten used to seeing “meta clocks,” clocks that use an array of analog clock faces and piece together characters using the hands of the clocks. They’re very clever, and we always like to see them, especially when they come with detailed build instructions like this one does. What’s also nice about [Erich Styger]’s “MetaClockClock” display

Retired scientist [Mark Howe] spent the last couple months making an animatronic movie featuring his LEGO lunar lander in a video recreation of the Apollo 11 moon landing (also embedded below). [Mark] is not only the producer, but serves as the technical director, set designer, and cameraman as well. He designed and 3D-printed a custom special effects

A wave tank is a laboratory setup for observing the behavior of surface waves. The typical wave tank is a box filled with liquid, usually water, leaving open or air-filled space on top. At one end of the tank an actuator generates waves; the other end usually has a wave-absorbing surface. Usually these tanks cost

Hi everyone! In this instructable, I tell you how to make split-flap display and show the current weather conditions on it. Also how to fetch the weather information from the Web using Wi-Fi and API. I am a fan of the XOD visual programming environment. With the 0.22.0 version, XOD entered the Internet of things. So
