In what is probably a fairly obvious and easy thing to do with Xbee, we have the arduino wireless programmer. This is a pretty cool idea because it clears up the mess of wires around your project and is very simple integrated into your project.

This project is a simple little frequency meter. It uses an ATMega microcontroller for its brains with a standard algorithm & timer for calculating the frequency seen on input. Newer microcontrollers will have CCP (capture & compare modules) that make this task a piece of cake, but a back to the basics look at thing never hurts!

The mini digital volt meter is a neat little project that uses a standard microcontroller for all I/O. The project write-up goes through the build process of the project & shows you how the software algorithm is setup. Hardware schematics & high level software algorithms are explained in detail, take a look.

Switch Debouncing is a problem that every hardware or software design runs into sooner or later. The problem is that humans can’t press a switch for 1/1,000,000th of a second. Read on for possible hardware & software solutions to this problem.

The standard NES controller has been made into mp3 players, walkmans & plenty of other random yet incognito devices. This time it has been made into a fully fledged computer mouse. Check out the project write-up to see how it’s made.

The ATmega TV Terminal is a simple project that connects together a keyboard, serial communication port & TV video output. The idea of course is to make the TV the output terminal. If you’re into AVR’s this is definitely a project you can learn alot from. PCB schematics, source code & an indepth project write-up are all there.

Digital Oscilloscopes made with microcontrollers are always both cool little gizmos and very useful. This AVR based oscilloscope is limited in features, however its small size and low build-cost make it worthwhile. Hardware schematics and software are available for download.

Using the basic theory of electrolysis it is fairly simple to split the Hydrogen & Oxygen atoms from water. This project write-up gives a straight forward approach using household items to accomplish electrolysis. Be careful around pure hydrogen, remember the Hindenburg disaster!

This project is very useful for anyone who wants to get started using USB for programming instead of that clunky old parallel programmer. Using creative programming the author of this project managed to convert between parallel & USB using the ATtiny microcontroller.

Many of you have likely heard of using a lemon as a battery. For those of you who haven’t or have always wanted to, this video gives a great demonstration that virtually anyone can follow along with.
