With this device you will be able to read the measurements made by a DIY multimeter directly on your glasses. No cables will be present as the multimeter will send the read data through the Bluetooth connection....

In this project we will see how a machine was built that takes out your tea bag when the previously set time expires. The Steampunk-style structure was built with 4mm plywood cut out using a laser engraver....

This project allows you to create a low cost GPS data logger for RC aircraft. A Data Logger allows you to record data from sensors and save them in a micro SD memory. In this case, data...

In this article we will see how to build a fire and gas detection system that also provides protection. We use Arduino Nano as a microcontroller and two sensors: MQ-2 gas sensor and the flame sensor. We...

This project is not only an intelligent coffee machine with smartphone control but also allows you to graphically view the temperature trend. It can be controlled via Bluetooth or simply fill up with fresh water and the...

In this project we will see how to make an RC controller that communicates using a 2.4 GHz radio signal. This RC controller was designed to be used with a quadcopter. The radio control was made in...

The “light painting” consists in photographing moving light sources and thus obtaining very particular and creative images; in this project we see how to build a bright skateboard for this purpose. We used an Arduino Nano as...

In this project we see how to make a lamp that can change its colour according to the environment, using the Arduino Nano microcontroller. We must therefore create an electronic circuit that takes a color as input...

Virtual reality technology has come a long way over the past decade, but there are still some things that could be done to make it even more interactive and engaging. What if virtual reality users could actually...

In this project we will see how to make a thermometer to measure the temperature in the room with a measuring range from 10 degrees to 35 degrees Celsius and an accuracy of 0.5 degrees. The temperature...

In this project we will see how to make a smart pot that can show the emotion of a plant. It uses a soil moisture sensor to monitor the state of the soil and then displays an...

Peter Balch, reading an IEEE report on speech recognition from the late 1970s, wondered if, with a normal Arduino Nano, it was possible to obtain the results of a computer of the time. Comparing the two tools...

Anyone can learn robotics, but what if there was a practical and inexpensive approach? This is where “Boca” comes in. Boca is a 3D printed open source platform for manufacturers and researchers interested in exploring control theory...

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...

Lately we see many commercial products that allow you to levitate light objects using a magnetic field. There are already assembled kits, but today we will see how to build a more simplified one at home. The...

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...

After losing the chicken due to wildlife intruders, Elbie decides to create a Smart chicken coop with several functions: Opening and closing the door at sunrise and sunset according to local geographic coordinates; Intrusion detectors with flashing...

Due to the pandemic, many people have been forced to stay indoors much more often, which means missing out on the usual social events, including sports and tournaments. Even playing a simple game of chess hasn’t been...
