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,...

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...

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,...

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...

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...

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...

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...

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...

  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....

A new Raspberry Pi stepper motor and DC bonnet has being designed by Adafruit and is now available to purchase from their online store priced at $22.50. The Raspberry Pi bonnet can drive up to 4 DC...

The new Snapmaker 2.0 is a modular 3-in-1 3D printer that doesn’t appear to have any downsides. It’s a well-made and capable 3D printer that also works as a laser cutter/engraver and CNC mill. Additionally, the kit...

Developed by students at the California Institute of Technology, Poseidon is an open source alternative to commercial syringe pump and microscope system. The Poseidon microscope consists of a Raspberry Pi, touch screen module, and commercially available digital...

If you wear a self-winding watch, I’m sure you’re aware that watch winders are generally very expensive, or cheap and noisy. So Kristopher Marciniak decided to hack an inexpensive winder replacing the stock motor with a stepper,...

  Set consisting of a stepper motor driver based on the ULN2003 chip and a 4-phase stepper motor. Equipped with 4 status LEDs for each phase of the motor, the driver is controlled via the 4 input...

Created by Tucker Shannon, the single pixel scanning camera uses a pair of stepper motors which directs the RGB color sensor (Adafruit TCS3472) in a square spiral for image acquisition: all powered by an Arduino Uno SBC. If you...

The maker Nikodem Bartnik has just created a 3d printed CNC machine that’s able to cut MDF and acrylic and can engrave aluminum. As for how well this CNC machine works, it’s pretty good. With the Gcode to cut...

How To Mechatronics has come up with a bender that not only twists wire left and right, but can rotate to create three-dimensional shapes. The 3d wire bending machine is powered by an Arduino Nano, which controls...

The Etch-A-Sketch was released by The Ohio Art Company in 1960. The popularity of the device is sort of interesting because it has lots of annoying problems: knobs only move the cursor up/down/left/right. Diagonals and curves require...
