AT Tiny Custom Dev Board

If you've ever wanted to make your own PCB board this is a great project write-up to read through. The author has built a custom board & layout for the AT Tiny microcontroller which he eventually turned into a line-following robot.

PIC Virtual Oscilloscope

The oscilloscope is arguable one of the most useful tools for electrical engineers. This is a small DIY oscilloscope that uses a simple PIC dev board and a computer GUI to display the results. .NET is used to store & display the data. Both hardware schematics & software are available for download in the project write-up.

Build A Chat-Cord

This project shows you how to easily (and cheaply) create a chat-cord. The chat-cord is something that has become increasingly popular in the world of VOIP. If you are a Skype master with some basic solder skills this should be a very easy project for you. Schematic details & parts lists is available in the project write-up.

DIY PIC Programmer

Most microcontroller programmers are actually very simple devices that can be made by yourself. Being that programmers range from $50+, so it can be a good investment or backup programmer. The parts are very cheap and this project write-up is clean with step-by-step instructions. Give it a look see!

Universal NiMH Charger

NiMH rechargeable batteries have been around for quite some time and have proven their worth. This type of rechargeable battery can be found inside things from electric cars to electric tooth-brushes. Today's simple project makes use of a microcontroller for controlling the recharging of the battery and turning off when recharging has completed.

Wireless Arduino Programming

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.

40 MHz Frequency Meter

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!
