We’ve all likely seen the amazing images possible with a scanning electron microscope. An SEM can yield remarkably detailed 3D images of the tiniest structures, and they can be invaluable tools for research. But blasting high-energy cathode rays onto metal-coated samples in the vacuum chamber of a bulky and expensive instrument isn’t the only way […]

Spooky teddy is a 2-part Halloween decor. The first part is the teddy bear that has a 3d printed mechanism that can rotate with an Arduino UNO and a solenoid. The second part is a self-rocking chair powered by an Arduino nano and a solenoid attached to the bottom of the chair. The two parts

Call us easily amused, but we think it’s pretty amazing what can be done with a microcontroller, some RGB LEDs, and a little bit of plastic. Case in point is [andrei.erdei]’s beautiful and quite approachable fiber optic LED lamp. It’s a desktop-friendly version of a similar piece [andrei] made that is roughly nine times the size

If you’re a maker that publishes projects online, you’ll be well across the production values arms race that’s been raging over the past decade. For those in the 3D printing space, this means that you’ll need to be producing slick timelapse videos of your prints. [BuildComics] is now doing just that, with a custom camera arm

Build yourself a low-cost easy to assemble bluetooth controllable robotic bartender using an Arduino Uno. This easy Arduino based project can be 3D printed and is a cool Arduino project for beginners. The aim of this project was to create a bar robot that was low cost and easy for anyone to write their own

Calculating on paper is never an easy job. And when it comes to formulas with sub-formulas of their own, it is nothing short of a nightmare! Take the case of a simple pendulum, which has a variable with a formula of its own. What if there was a way to replace these scary calculations with

Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input, and we’ll build on those skills in this lesson. Ultrasonic

Repetitive tasks in video games often find a way of pushing our buttons. [Facelesstech] got tired of mashing “A” while catching shooting stars in Animal Crossing, so he set out to automate his problem away. After briefly considering rigging up a servo to do the work for him, he recalled a previous effort that used an Arduino

Rollercoasters are great fun if you can deal with the exhilaration without throwing up or otherwise screaming until you pass out. Of course, the big outdoors ones are a little hard to get to at the moment, what with a pandemic raging outside. However, [3d_coasters] has built a tabletop design that, while it’s too small to ride,
