IR sensors (emitters/receivers) have the unique quality that they can sense things that are in front of them. This project goes through the theory and shows you both how to use them and what to expect from the sensors.

If you’ve ever been curious about simple breathalyzer theory this project is for you. They used a MQ-3 alcohol gas sensor and an arduino board to build it. The write-up has the software, hardware and a video of the working project in action.

Sim Cards and Smart Cards now have a large presence throughout the world and understanding how to read them is a interesting process. All these cards use a similar serial communication process and this project write-up explains how to read the memory from a telecard.

This project uses some creative thinking to build a binary clock that runs off of analog circuity. A wheel similar to an encoder wheel is used that slowly spins to give you the time in binary code. A great project for anyone willing to expand their mind beyond the base 10 number system!

Ugly Electronics Construction is something that seems to be reserved for either lazy people or abstract artists. This website goes through some examples of horrid looking but working electronics that are soldered together in ways that defy logic. Take a look to learn how to do it or just to get a good laugh.

This is a very unique way to create wireless communication and it gives a lot of range. Using two radio modems this guy makes it so two basic stamps can communicate serially. The project write-up explains the process very well.

This DIY Thermostat project is exactly what you think it is, a thermostat you can make on your own. It uses a temperature sensor and a ATtiny as a brain. Two seven-segment led bars show you the current temperature and you can set the thermostat using them as well. Board design, hardware & software are all available in the project write-up.

This line following robot was done for someone’s thesis so the write-up is very indepth. It goes through the basics of motor control, sensor control and combining the two using a microcontroller.

Today’s project shows you how to make a hand crank that can recharge your Ipod. Obviously you’ll run out of energy after a few minutes, but you’ll be able to listen to music while you’re at it. The write-up is very detailed, take a look.

This project uses a sharp IR sensor and some data processing. Then the data is visualized through a program. Visualization of data creates a way for us (humans) to understand data quicker, compared to when it is in raw number format.
