As a maker, we are always looking for the best way to power our projects. Usually, buck and boost converters are a considerable part of our project, because without good power, then everything else can be compromised. As important as it is, one does not want to splurge huge amounts of money on something that […]

In this project we built a sketchpad based on LED matrix display with microcontroller and resistive touch screen control. We used a single point resistive touch screen to detect the userās gesture and microcontrollerās analog/digital converter (ADC) ports collects the data and convert it to coordinates. We designed a LED drive circuit with shift registers
Introduction What is seeing without feeling? The field of Virtual Reality has recently been gaining much attention, with the Oculus Rift and Google Cardboard paving the path of visualizing a world that is not physically there. But what if the virtual reality experience could be enhanced by incorporating tactile sensing? The Haptic Glove we developed

INTRODUCTION This project implements a real-time scrolling spectrogram-style visualization of an audio signal. We successfully displayed the frequency spectrum content in real time using a 4-bit grayscale scrolling display on any NTSC television. The frequency spectrum of an audio line-in input or mic input is calculated and displayed in real time using two ATmega1284 microcontrollers
