In this project we will see how to build a professional quality seismograph, completely open source, based on Raspberry-Pi and able to record earthquakes or other seismic events, natural (rockfall, glacier movement) or artificial (train detection, detection of vehicles). The seismograph works autonomously in the field, or it can be used as a seismic station….
The project was born with the purpose of helping the deaf community to communicate and interact easily with the surrounding environment. The goal is to convert the basic symbols representing the 26 letters of English alphabet and display them on a smartphone screen. For this system we were inspired by the idea of controlling a…
Can we “listen” a difference between pouring hot and cold water? As you see in the video you can do it, but why? It is mentioned that the change is due to complex fluid dynamics reasons. Beyond the scientific investigation, the question we asked ourselves was: is this ability to “listen to temperatures” something that…
In this project we see how to make a Bluetooth speaker with a clock. It displays date, time, temperature and humidity and it is updated from Internet at 15 minute intervals. It also has a 32-band audio spectrum analyzer that displays different musical patterns. The clock or spectrum analyzer can be displayed while playing music….
In this project we see how to create an I2C system to control motors using a DigiSpark Attiny85 plus an Arduino shield. To test its operation we made a small RC car that uses an M5StickC and connects to the Blynk app to communicate via the I2C protocol. We used two communications in this project…
In this project we will see how to make an anemometer (instrument for measuring wind speed and direction) using an Arduino Uno R3, two VL6180X laser distance modules and a section of tube made of plastic or similar materials. We will also use Processing3 to display wind speed and direction, the latter being independent of…
Relationships and mathematical patterns are all around us, in our daily life as well as in nature. These patterns can range from simple to complex, from harmonious to chaotic. Regardless of the type of pattern, these geometric figures intrigued us so much that we decided to investigate the underlying mathematics. In the following project we…
The idea of this project is to show the high and low tide times predicted for the day and a graph with the trend in the last 24 hours. In addition to this we also find basic meteorological data. We use a Raspberry Pi (in this case Raspberry Pi ZeroW) as a microcontroller and an…
The project attempts to recognize different bird calls by continuously listening to audio through the Nano 33 BLE Sense’s built-in microphone. The call of the bird heard will be analyzed and classified; if it is not heard, the audio will be classified as background noise. This project can be useful for people interested in birding…
The Maslow is a large format CNC router capable of cutting wood and other materials with precision and repeatability, based on a digital file. A CNC (computer numerical control) machine allows manufacturers to automate the cutting process in woodworking and other manufacturing operations. Once the Maslow is built and the software installed, you will have…
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…
The recognition of vehicle number plates is a process as complex as it is necessary, used for example at motorway toll booths or to identify who violate traffic rules. Here we propose a Raspberry Pi-based system that automatically recognizes vehicle license plates using image processing. The system features an HD camera with infrared sensor and…
