This page explains how to make a simplex repeater using a $25-$35 Raspberry Pi, a USB sound card, Python code, and a two-way radio. A simplex repeater is another name for a store-and-forward voice repeater. Contrary to a standard duplex repeater that operates on two frequencies simultaneously for receiving and transmitting, a simplex repeater initially […]
The upcoming brief Python scripts will showcase the fundamental functionality of the Raspberry Pi Pico board. These presume that one or more binary input or output circuits are connected externally. You can activate each one by pasting the program into code.py on the CIRCUITRY drive provided by the board. The text is available for copying […]
N.B. This is new and still being tested. The provided Python examples showcase different single-channel filters that can be used to manipulate sensor data. The filter functions are only numeric operations and should operate on any Python or CircuitPython system. This enables testing without an internet connection, as they can be fixed and assessed on […]
Device for intelligent waste bin. This device integrates several sensors to supervise the state of the trash. Story Content guidelines Context Effective waste management is now a crucial concern for our planet. In both public and natural environments, a considerable number of people fail to be mindful of the garbage they discard. When a garbage […]
Other applications of facial recognition include the use in surveillance and security due to enhanced technology in the Facial recognition system. This guide will go over how to create a facial recognition door lock system using a Raspberry Pi. There are three main steps: Collecting data: We will gather approved facial samples to unlock the […]
Below are brief Python scripts that showcase essential functions of the Raspberry Pi Pico microcontroller. These devices assume that one or multiple I2C (or I2C) devices are connected externally. The I2C bus is a two-wire bidirectional serial bus used for short-distance low-bandwidth communication between a microcontroller and peripheral devices. To execute any sample, just copy […]
In this tutorial about a light sensor for Raspberry Pi, I demonstrate the proper way to connect the photoresistor sensor to the GPIO pins. Finally, I demonstrate how to incorporate it into a basic Python script to enable data retrieval and utilization. This is another sensor that I am considering for inclusion in upcoming projects […]
Use a Raspberry Pi to make your “dumb” car smarter! Story INSPIRATION I think smart cars are great, but buying a brand-new car just for a few extra features seems difficult to justify. At the moment, I’m currently limited to my “dumb” car, however, that doesn’t prevent me from attempting to enhance its intelligence on […]
TNC-Pi is a unique variation of TNC-X made specifically to connect directly with the Raspberry Pi device. It has the option to connect to the Pi through either the Pi’s serial port or the I2C protocol. In this scenario, one Raspberry Pi can accommodate several TNC-Pi devices simultaneously by assigning each TNC-Pi a distinct I2C […]
