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, âgee, thatâs not a very creative designâ. 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 itâs Engineers Week 2011 activities. We spent the day assembling a 8Ă8 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

As simple as it gets and still works This LED flasher occurred to me while reading about negative resistance in transistors. It was reported that Leona Esaki, who was at Sony at the time, had been surprised to see a negative resistance region while investigating production defects in transistors which lead to his thesis work

A circuit that drives a red LED from a 1.5 volt battery and simulates an incandescent light. Duty cycle can be changed by selecting resistor values. Photo 1. This printed circuit board is 3 cm long. The first prototype was made with through hole parts. This is a single sided surface mount board with one
Finally, white LED’s are bright enough to use in a practical stroboscope. This circuit can operate as a bench-top stroboscope that, in conjunction with an oscilloscope or frequency meter and bench top power supply can accurately measure rotational speeds, or it can be operated hand-held from a single 9V battery, using a marked scale to
