Introduction With the increasing awareness of sustainable and green building, more and more people are concerned with the efficiency of energy use at home and at work. For our ECE 476 Final Project, we developed a microcontroller-based, interior illumination system – The Heliostat Skylight. By reflecting light that would otherwise be lost, the Heliostat Skylight […]

Introduction Our project, in one sentence, is an orientation independent 3D LED display. We were inspired by various videos on youtube of similar cubes but also by the idea of creating an interactive 3-dimensional display. We built a 5x5x5 LED cube display and controller board which interfaced the cube to a Mega32 microcontroller. We can

Introduction Overview SecureLED is an optical access control device which replaces current RFID or Magnetic Strip technologies with a cryptographically secure, contact-less device which communicates over commodity Light Emitting Diodes (LEDs). Project Summary This project started with one central premise: current physical access control systems are insecure in fundamental ways. We sought a way to

Introduction For our final project, we decided to build a digital message machine which displayed on a mirror. This is a variation from other digital message machines we had seen in stores and in past final projects. Instead of quickly moving a wand of LED’s to display the message on, we decided that holding the

LED Dog Collar So this is a pretty simple project, but I thought it was a clever idea. I have 2 dogs, a lab and a lab mix. The lab “Sunshine” likes to runaway a lot if we let her outside at all. She always comes back, but we can’t find her whenever she leaves.

The classic pong game. Two players. Press the buttons to move paddles up/down. Ball bounces back and forth. If you fail to catch it, your opponent gets one point. Score difference is showed with blue LEDs. Blue LED = lead by one point. If you then win another point, you win the game, and your

Last week on hack-a-day I saw their post on an LED Menorah that was powered by a 9v battery with the lights controlled by dip switches. I thought to myself, “gee, that’s not a very creative design”. There was redemption in the minimalist designs linked too showing a menorah soldered to a tiny2313 and one

Last Sunday I gave a workshop in TOG as part of it’s Engineers Week 2011 activities. We spent the day assembling a 8×8 Red/Green LED Matrix Display circuit which I designed in strip board. The circuit forms an interface between a micro controller and a 8 by 8 Dual Colour Common Anode LED Module. This

If you’re a resident of Seattle, I highly recommend you check out the Bubble events group. One of their regular events over the summer is something called “Nocturnal Push” where you can get decked out in your best glow gear and cruise the Alki Beach strip on your bike, longboard, or whatever. That’s why I
