POV’s have become quite popular recently and they have hit the DIY crowd just as hard. Most of the DIY POV’s are made with standard lasers you can buy anywhere. This detailed project write-up is devoted to explaining how to make your own DIY POV.

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.

Here is another interesting linux based project, although seemingly a tad overkill. This project takes data from a solar station and e-mails it to you at intervals you chose (i.e. once-a-day). The project write-up is very detailed from all aspects. Definitely worth a read.

The GunBot is basically a remote controlled gun and is a more difficult project as it involves both remote vision and control. Only a high level detail of the hardware & software is provided by that should be enough to get anyone started with a project similar to this one. Take care not to shoot anything that could be harmed!

This project is an autonomous blimp with surprisingly simple circuitry for controlling it. Autonomous blimps are quite a hassle to make because electronics (especially batteries) can start to weigh a lot very quickly. All schematics and a few videos are there waiting for you.

If you’re a linux guy and have always wanted an ‘in’ to the world of microcontrollers then this article/guide is for you. It’s not really a project so much as a very well written how-to develop for Atmel’s AVR using the linux gcc compiler. A great alternative from the Windowz world.

This LCD controller (HD44780) is the most widely used on LCD segment displays. The link for today leads to a plethora of background information on sending commands to the controller as well as software examples for many different devices.

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.
