DubStep. Food for thought.

2 days ago, I was sitting in my Calc class and one of my colleagues handed me his iPod and asked me to plug it into the new room's speaker system to test it out with some dubstep. But rather quickly the teacher came down on us. That night in the shower, a thought crossed my mind. The speakers weren't wireless, but they did have wires. I wondered if it would be possible to modulate the audio signal from the iPod with a low frequency, high amplitude, carrier wave, send that signal through the air to the wire where it would then induce a signal that would be amplified and played by the speakers. It makes sense, I've been able to achieve a similar effect with radios and short range transmitters, so why shouldn't it work over a larger scale.

Electronics 201: Pull-Up and Pull-Down Resistors

In today's lecture, we go over the useful tool that is the pull-up and pull-down resistor.

Computer in a Suitcase

I've always been fascinated with technology of the past. Perhaps not the distant past, but definitely within the last half century. One such piece of nostalgia is the Altair 8800, what is probably the first personal computer. What I want to do is recreate that sort of device within a suitcase, it makes sense. I'm going to use the Z80 microprocessor, the same processor in the TI-83 and 84 calculators, and the Altair's switch based programming and 5 expansion ports to create this device. I'm already working on a schematic for the entire thing, but I doubt the board will be something I can etch in my backyard.

Electronics 101: Capacitors

In this lecture, we go over the analog component that is the capacitor.

Learning AVR-C Episode 2: Setup and BlinkLED

In this video we go over the setup of the programming board we're going to use throughout the rest of the series, the basics of registers and the BlinkLED program.

Electronics 201: Digital vs. Analog

In this video, we start the Electronics 201 lecture series where we look at the more digital side of electronics as opposed to Electronics 101's analog electronics.

Arduino Tutorial #2 (Blink LED)

Here is my second Arduino tutorial where I go over the setup of the Arduino IDE, drivers, and some basic programming.
