In this article I describe how we made an hour glass with leds as the sand. We were always interested in making something that visually flows like sand and decided to use an hour glass to start. The movement is not completely fluid given the resolution of the amount of pixels, but it does resemble […]

As an artist, sometime I created an art pieces without planning ahead what I want to draw or paint, just want to add colors or lines onto the drawing or canvas, and never think of the outcome of the piece. Let’s our own instinct and subconscious leading away! Then I thought, “What if I am using electronic components,

I do project related works. After the structure contractors finished their building works, they threw away a lot of washers and nuts M10. During I did cleaning, I picked them up to make this decorative see-through led project. It can be viewed from frontside or backside by a push button. Let’s watch videos bellow before

Faced with an old console stereo from the 1960s that was barely functional, [Sherman Banks] aka W4ATL decided to upgrade its guts while keeping its appearance as close to the original as possible. This stereo set is a piece of mahogany furniture containing an AM/FM stereo receiver and an automatic turntable from JCPenny’s Penncrest line. As best [Sherman] can

Quantum computers aren’t quite ready for the home lab, but since there are ways to connect to some over the Internet, you can experiment with them more easily than you might think. [Norbert] decided to interface a giant quantum computer to an ordinary Arduino. Why? Well, that isn’t necessarily clear, but then again, why not? He

Arguably the biggest advantage of the Arduino ecosystem is how easy it is to get your code running. Type a few lines into the IDE, hit the button, and in a few seconds you’re seeing an LED blink or some text get echoed back over the serial port. But what if that same ease of
