In this project we see how to build a logic probe, that is a complete, simple and effective instrument that allows you to measure digital logic levels 0 and 1, both in TTL and CMOS technology. The maximum accepted level is 10 volts but CMOS can reach up to 18 volts (however best avoided). To…
In this project we will see how to build a home automation greenhouse with Arduino Uno that allows you to grow plants even in unfavorable weather conditions. In addition to recreating an optimal environment, a domotic greenhouse allows the automation of fertilizer administration and controlled irrigation. Furthermore, by monitoring environmental factors in real time, you…
In this project we are looking for a solution to control the humidity level in the bathroom. In particular we will try to control an already present fan that is operated manually. You can of course buy a fan with an integrated controller, but this is often expensive and with limited manual settings, here we’ll…
Fed up with shaky footage ruining your video? In this project we will try to address this problem by building an automatic slider for the camera. We create a robust system where the camera slides along a square tube with a pan and tilt mechanism that gives the user the ability to capture any angle….
In this project we will see how to make a 3D printed pet feeder. All modeled parts are available for you to replicate the project in your home. The system is very simple: you are asked to enter two times when you want to distribute food, for example 8:30 and 17:30, then, at the indicated…
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…
Grumpy Hedgehog is a device that allows you to interact with electronic devices through movements. We can easily create our own movements and patterns to transmit actions through different communication channels (USB HID, Wifi, IR …) or simply use its relay and servo motor. The system is based on the VL53L1X time-of-flight sensor, a technology…
In this project we will show you how to build your home emergency light. The idea of the following circuit is that it must be compact and may be kept plugged into the mains socket for a permanent automatic operation. The battery can also be charged via a solar panel when the power grid is…
When you test a new electronic circuit or new hardware design it’s useful to check if the components on the board are overheating abnormally. If something goes wrong (which can happen on the first try) these components could reach a temperature of up to 80 ° C and touching with your finger is not a…
In this project we will see how to make a low cost smart mirror from readily available parts. It all relies on the use of a regular picture frame, and mirrored window film to turn the glass into a two way mirror. Then enclose a monitor in the frame and hide it behind the mirrored…
Home security systems are a growing field of projects. A self-built system is not only generally less expensive than a professional installation, it also allows total control and customization to suit your needs. With the introduction of Microsoft Project Oxford, facial recognition applications are now more accessible than ever to makers. This project uses a…
Roni Bandini is a writer born in the seventies, obviously he likes paper books but after many years of using a Kindle he has become accustomed to some features that he doesn’t want to lose. What features? The remaining reading time for example. Can this feature be implemented for paper books? The first thought was…
