Halloween is right around the corner and just about every Halloween project needs some kind of motion sensor. Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest animatronic creation. You can see a video of the device and how it works below. The […]
Interested in making a useless box? Building this project was a really fun experience for me. Having very little prior knowledge about circuits, making this simple gadget was a great introduction to circuits for me. And, it’s really fun to play with once completed! This project is meant for beginners with little or no experience
Got a couple of old DVD-RW drives lying around, just collecting dust? Of course you do. If not, you likely know where to find a pair so you can build this totally adorable and fully dangerous laser engraver for your desk. Check out the complete build video after the break. [Smart Tronix] doesn’t just tell you to

When your friends are off to the post-apocalyptic Wasteland Festival and present you with a defunct Power Wheels clone toy Jeep to make ready for the festivities, what are you to do? If you happen to be [Victor Frost], soup it up with new electrics and uprated steering, and send it forth into the hideous no-mans
Growing basil is great, but do you know what’s even better? Having an autonomous basil farm! As the saying goes: “never spend ten minutes doing something by hand, when you could spend 10 hours failing to automate it”. Although I may be bad at gardening, something I am good at is enthusiastically trying to solve
Sure, we see quite a few plotters and other motion machines, but the one from [DAZ Projects] has the virtual of looking dead simple. The Arduino and CNC shield are old hat, of course. But some 3D printed pulleys and a very simple-looking core XY arrangement looks like this could be a pretty quick build. You might

The new design of the 6WD mobile platform, the vehicle uses 2mm aluminum alloy, aluminum spray surface treatment. 6 high-speed DC motor (original 17000 rpm), with 1:34 full metal gear box, so that the car to obtain strong off-road performance. Shock absorption design is the highlight of the car, the use of 6 damping shock
We’ve grown to expect seeing mechatronics project incorporate a standard complement of components, things like stepper motors, Arduinos, lead screws, timing belts and pulleys, and aluminum extrusions. So when a project comes along that breaks that mold, even just a little, we sit up and take notice. Departing somewhat from this hardware hacking lingua franca

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,
3D PRINTED ROLLER COASTER LOOKS PRETTY DARN FUN Continue Reading
If you march sufficiently deep into the wilderness of control theory, you’ll no doubt encounter the inverted pendulum problem. These balancing acts have emerged with a number of variants over the years, but just because it’s been done before doesn’t mean there’s no space for something new. Here, [David Gonzalez], has taken this classic problem
