I usually can spot scam emails right off the bat, but I have to admit, this one almost got me.

When I tried to import my localhost MySQL database sql file into phpMyAdmin today I was greeted with the following error:

My old car, or should I say, my very old car, recently broke down. If it weren't for the fact that I don't have much money, I would have rejoiced in the car's demise. Really, I would have. You have no idea how much pain my old car caused me.

Since I commute to school I had to quickly buy a new car. Of course, when I say new...

The final project in one of my engineering classes this semester is for my lab partner and I to build a circuit to drive a solar garden light. This is our pre-report for the project, which gives a general overview of how we intend to complete the project.

A recent project I worked on was interfacing an accelerometer to a PIC18F4550 and displaying the sensor data on an HD44780 display. When writing my HD44780 framework code (check out the...

If you're viewing this website for the first time, you might be wondering why all of the blog posts, tutorials, downloads, and gallery images were all added in just the past few days. No, I haven't gone on a blog posting, tutorial writing, file posting, image uploading spree, but rather have changed the CMS the website uses.

This board was designed for use as a general prototyping board, as I needed something a little more robust then my previous one. The main reason for building this, was that I needed a serial connection to a PC for debugging. It's hard to learn ADC's, Timers, PWM etc. without...

My first L297-298 stepper motor controller was made on prototyping board, which turned out to be a nightmare for two reasons. One, it's really hard to keep track of all the wires and where they're supposed to go when you're trying to assemble the board. Two, I meticulously made the wires all the "right" lengths because I wanted the stepper motor...

I designed this board to be a general-purpose experimentation board to help me learn about the PIC184550 USB module (or SIE). This was meant to be a kind of "step up" from my dsPIC30f4011 board which uses an RS-232 serial interface for communication with a PC. I really wanted to move from using RS-232 to USB, as USB is the new standard these days...
