This guide will explain the basics of controlling multiple 7 segment displays using an Arduino and a couple of shift registers. This project is ideal for displaying numerical data or managing a set of LEDs. As a beginner, like me, I had no clue on how to tackle this task. After trying out different methods […]

This project brings back the old time Analog VU Meter, with the added functionality of a neat looking clock! When you turn off your music the meters automatically swing into to clock mode. Behind it all is the popular and easy to use Arduino. This is my submission for the Make-to-Learn Youth Contest: What did

A key factor when building a pinewood derby car is its weight. The Boy Scouts of America and other organizations specify a weight of no more than 5 ounces. To improve performance many builders will add as much weight (mass) as possible up to that maximum allowable weight limit. What is often overlooked is the

Have you ever wondered about the radiation levels around you? Well today you can build your very own detector that measures ionizing radiation and displays data in real-time on an LCD (and also your computer if you want). The visual design, as seen below, is perhaps a tad short of a Red Dot Award, but
