A mechanical 7-segment clock
We are used to seeing clocks with 7-segment displays which, through the switching on and off of some LEDs, form the numbers. This project is different, in fact instead of the LEDs we find stepper motors that, by setting the rods in motion, allow the visualization of the numbers as if it were a classic…

Automatic cereal dispenser with facial recognition
The goal of this project is to create a device that contains cereals and opens the cap to release part of the cereal and then closes it again. The user will only have to place their bowl under the preferred cereal and an artificial intelligence algorithm will detect the face and release the correct cereal….

Automatic cereal dispenser with facial recognition
The aim of this project is to create a device that uses Artificial Intelligence to detect the faces of those who want to have breakfast and pour the cereals they have previously chosen. On a practical level, users place their bowl under the cereal they prefer and an artificial intelligence algorithm detects the face to…

Eggbot: the robot that draws on eggs!
The project consists of creating an eggbot, an artistic robot that can draw on spherical or egg-shaped objects using an Arduino Uno development board. This project is a good introduction to CNC machines because you can learn the concepts of firmware and hardware that involve them in a fun way. The robot needs two stepper…

Vertical surface plotter based on Arduino
This plotter, based on Arduino, allows you to draw on a vertical surface, such as a blackboard, using a normal marker. As you can see from the video, the central block, where the marker is located, is connected to two cables which, according to their length, make it move along the surface. The project is…

The Arduino based machine that cuts the cables
If you need to strip a cable or two, that’s easy enough. However, if you have to strip and cut several dozen cables all to the same length it becomes a boring thing. This is why Mr innovative has created a machine that cuts or creates surface cuts to facilitate peeling in user-defined points. The…

3D Printed Mini CNC Machine
In this project we will see how to create a 3D printed CNC machine. It’s just a prototype, but once it’s built you will surely be able to build a larger, more accurate one. The principle will be the same, but in this case we use DVD writers stepper motors to control the motion of…

Control Stepper Motor with A4988 Driver Module & Arduino
If you are planning on building your own 3D printer or a CNC machine, you will need to control a bunch of stepper motors. And having one Arduino control all of them can take up a lot of the processing and not leave you a lot of room to do anything else; unless you use…

Mesmerizing Magnetic Wall Clock
Mechanical clocks have always fascinated me. The way all of the internal gears, springs, and escapements work together to result in a constant reliable timepiece has always seemed out of reach for my limited skill set. Thankfully modern electronics like Arduino and 3D printed parts can bridge the gap to create something simple that…
