This robot has built in functionality for line following, object avoiding and ‘victim finding’. A PIC micro allows to it be able to do all these at once. Check the project write-up to see the hardware schematics, software & parts list.

Wireless Audio has been kind of slow to make a big impact on the commercial market. So why not build your own? This project shows you how to build some wireless speakers to setup outdoors or indoors. The electronics are not overly sophisticated and the project write-up very thorough. Take a look!

In a true ‘build it as fast as possible’ style, we have the GPS Altimeter project. Built for the USC Rocket Propulsion Lab, this project tracks the peak altitude reached along with the descent back to earth. Schematic (hand-drawn) and source code are available for download.

Drop-dead simple RF transmitters are hard to come by, but this project breaks that trend. With only a few parts and some simple soldering this project shows you how to build an RF transmitter and receiver using RS232 serial ports. The data is coded in ascii and transmitted at 1 MHz.

The LM35 temperature sensor is used in this project to sense the temperature and relay that information back to a PIC micro. The project setup is: PIC, LCD and Temp sensor. The temperature results are displayed back on the LCD.

Today’s PyroElectro Tutorial shows how infrared remote controls work and guides you through the process of building an infrared IR receiver. The receiver decodes the infrared commands sent to it by a remote control, and displays them on an LCD for verification.

If you ever thought those little AVR microcontrollers were not so powerful, this project should prove you wrong. This project uses a 12 Mhz AVR to output complex grahics and basically an operating system to a touch screen LCD very similar to an iPhone. Hardware schematics & source code are all there for you.

Reverse Engineering is an important skill for electronics hobbyists because very often you will run into something you want to use, but don’t know how. An LCD is a tough thing to reverse engineer, but this tutorial shows you one approach to figuring out how to get things working.
