While building your own set of noise canceling headphones might turn out a bit big and bulky the theory behind how they work makes this project worth a read. Noise canceling headphones hit commercial markets a few years ago and are now very popular, especially among business travelers.

In an unordinary twist, here is a far more software based tutorial. File servers are the core purpose for any server aside from databasing. Using the Kubuntu flavor this tutorial guides you through the process & necessary commands for getting everything ready to go.

This project is border-line indescribable. Using an old TV a really sweet arcade game setup was created. He’s actually not 100% finished with it but the progress shown is pretty sweet and most importantly; already functional.

Simple transistors radios have been around for a long time and since they are quite easily built a variety of circuit diagrams for AM/FM exist. This project goes through (the old “radio shack special”) and explains what goes where for a very simple FM radio and even offers an example PCB layout. You may have already heard of the Radio Shack Special, but now you can check it out.

This robotic arm has 5 degrees of freedom utilizing standard hobby servo motors. The grippers are quite strong, the software is very user friendly and the mechanical structure very sound (albeit out of wood). The author also includes some nice schematics, pics & a cool video. Give it a look!

One of the newest technologies to hit the commercial market is the accelerometer sensor. It’s in cell phones, the Wiimote and many other consumer products. They’re cheap, accurate & have a decent response time. This article goes over what it is, how to use it & how to understand the data using an AVR microcontroller.

FPGA/CPLD devices don’t inherintly have or require clocks so timing can become an issue when you want to talk with a processor or instruction based machines. If we add a clock input like the UP2 has onboard, we can now control timing precisely. This tutorial does just that.

CMOS cameras have recently become inexpensive for hobbyists and clean interfaces have been developed for them. This project uses an ATmega16 microcontroller to capture and output data from the camera. The complete report write up and source code is available for download so take a look!

The two main programming languages for fpga/cpld devices in the world today are Verilog & VHDL. Both are concurrent programming languages (similar to Ada) and both are used globally. The difference between them is merely syntax, formation but not funcationality. This tutorial provides an intro to VHDL using the altera UP1/UP2 board.

Breakout has remained close to every gamer’s heart since early on in gaming history. This project website explains how to build a simple AVR powered surface mount setup of the classic game. The layout is very clean since it is surface mount & the author offers all source code for download.
