Rube Goldberg machines are usually over engineered devices that perform a series of simple tasks to complete another simple task. Today’s write-up is from a professor from Portland State University who created a computer out of relays. Watch the video to hear them clicking away as it calculates.

This little robot is quite innovative in design. Each of the 4 wheels is independently steered, along with some sensors to guide it. Many videos, the CAD layout & prototype designs are all in the write-up.

Another cool application of accelerometers is in this acceleration sensing glove. This project write-up comes from a student at Berkeley tasked with deciphering hand motions/gestures. The software & schematics are all right there waiting for you.

This robot is a direct creation from Cornell University’s ECE 476 Microcontroller course. Using a microcontroller it actively seeks out the source of a sound and moves towards it…audio source tracking!

Keyboards are all around us yet the information for interfacing with them is somewhat a mystery. This tutorial shows you (with a working example) how to interface a keyboard with the Altera UP1/UP2 board.

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!

However dangerous it might seem, it actually works! Controlled by an AVR microcontroller, this self balancing unicycle looks and runs like something that might have been a possible segway. The parts list, software & other useful downloads are all there waiting for you.

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.
