Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

The growing availability of low-cost air quality sensors is helping people across the world track air pollution. Headway The growing availability of low-cost air ...

Have you ever wished you could revisit the golden age of gaming, where pixelated adventures and 8-bit soundtracks ruled your afternoons? With the power of the Raspberry Pi 5, that dream is no longer ...

When Raspberry Pi released the Pi 500, as essentially an RPi 5 integrated into a chiclet keyboard, there were rumors based on the empty spots on the PCB that a better version would be released soon.

The project can be used effectively to detect fast moving objects using sensors made from LED array. One of the slave microcontrollers (Slave A) is the PIC16F876A which autonomously scans the bottom ...

In this module we will wire up an ultrasonic sensor and attach it to our Raspberry Pi. Using the ultrasonic sensor we will measure the distance an object is away from the sensor. The distance of the ...

This module uses an ultrasonic sensor to trigger certain notes to be played through the pi. An object is held in front of the sensor and moved either closer or further away to make music. This is ...

Fluid-Implicit-Particle or FLIP is a method for simulating particle interactions in fluid dynamics, commonly used in visual effects for its speed. [Nick] adapted this technique into an impressive FLIP ...

What if you could build your own high-performance, scalable data storage solution for a fraction of the cost of commercial options? Imagine a sleek, compact system with swappable drives, RAID 5 ...
