Build a scriptable USB keyboard using a Teensy board that emulates a standard keyboard and can be controlled over serial from a laptop or a Raspberry Pi, letting you interact with pre-boot menus and BIOS settings without a physical keyboard.
Discover the ePaper smart journal, an open-source electronic notebook built with a Raspberry Pi Zero 2 W, a Waveshare ePaper display, and an M5Stack CardKB keyboard. It offers the simplicity of paper with the power of a computer, perfect for capturing ideas without distractions.
This article shows how to drive a large WS2812B LED ring with a Raspberry Pi Pico or Pico 2, creating festive light effects and even using the ring as a low-resolution display.
Based on a single chip from Terminus, it allows you to connect four USB devices starting from a micro USB port; the form-factor is designed for pairing with Raspberry Pi Zero. We all know what a USB hub is, since at least once we all had to deal with it at home or…
In this project we will see how to use Home Assistant software to create an intrusion alarm system for your home. The system will basically detect if the door is opened without authorization and then send a notification to your smartphone. We will use a magnet with a reed switch to determine if the door…
The project is dedicated to plant lovers who want to create timelapse videos like the following. Of course you can use it to film anything you want. The author of the project, not having a suitable video camera, decided to use a Raspberry Pi. Several tests were carried out regarding the camera but in the…
I wanted to please a friend, an environmentally conscious friend who is concerned about mould spores in the air (from damp), additionally he is an occasional smoker and lives on a fairly popular city road, so he’s keen to see what’s present in the air as far as concentration and air quality go. To…
With a Raspberry Pi, you can build a computer in countless different ways and styles. This is the case of the computer built by Max of Make’n’Modify starting from an old suitcase found in a garbage can. The final result recalls the suitcases present in the tanks. The project consists of a Raspberry Pi 4B…
In this project we see how to build a device that detects maturation stages based on color with a neural network model. As fruits and vegetables ripen, they change color due to the four families of pigments: chlorophyll (green), carotenoids (yellow, red, orange), flavonoids (red, blue, purple), betalain (red, yellow, purple). These pigments are groups…
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….
In this article we will look at the design and construction of an inexpensive FM stereo receiver for the Raspberry Pi, with impressive results for the cost. Many FM receiver designs are centered around the RDA5807 or TEA5767 ICs, however Quintic Corporation’s QN8035 will be used in this design. A handful of discrete components on…
