An old PC case becomes a Halloween vending machine

Arduino Team — September 8th, 2025 Halloween is creeping up on us like some kind of impatient ghoul, which means that half the maker community is currently scrambling to throw together some spooky projects. Those projects become a lot more approachable when you start with something the already exists—anything, really. For example, Appalachian Forge Works began this Halloween vending machine project with an old PC case. Used PC cases are easy to find for free or...

This novel 3D printer kinematic system uses a mouse sensor for closed-loop control

Arduino Team — August 12th, 2025 Robert Murray-Smith wants to experiment with a novel 3D printer kinematic system that drives a round bed through a friction interface — essentially a polar 3D printer, but without the backlash associated with gears. However, friction drives have a tendency to slip and so he will need closed-loop control of the system and that will require a sensor to monitor position. In a recent video, he demonstrated how it is...

This Arduino failsafe protects an amazing backyard observatory

Arduino Team — June 3rd, 2025 Nothing quite compares to the feeling of looking up at the cosmos on a dark night, and even an affordable telescope can enhance that experience. But if you’re willing to spend the time and money, you can take things much further. That’s what Redditor CosmicRuin did when they built an amazing backyard observatory. And they recently designed this Arduino-based failsafe to protect that observatory in the event of a...
