Ultrasonic transceivers are fairly cheap in price, but the controller boards are always far more expensive. This project write-up shows you how to build your own controller circuitry for some ultrasonics, saving you a bundle of cash!

Using off the shelf parts and a standard PIC microcontroller here’s a weather station that you can access remotely. The PIC takes care of all the data acquisition and serial transmission. Hardware schematics & software are included in the project write-up. Take a look!

Here’s another great analog project: A DIY Geiger Counter. The parts are all, for the most part, off the shelf and easily assembled together. The project write-up is extremely detailed with everything you’d need.

For people who are ‘musically’ inclined here’s a great project. The Laser Harp is exactly what you think, no strings, just lasers! The project write-up includes a lot of info on how to make it and an awesome video of the Laser Harp 2010 in action.

This is a cool little project that uses a PIC microcontroller to build a voltage output display for a variable power supply. The circuit schematic and software for the pic are included in the project write-up. The pure simplicity of this project is very refreshing, take a look!

In a little more sinister project, this guy used an AVR micro controller to act as an RFID tag. Hopefully the security gurus see stuff like this in action and realize how bad access control security really can be. The write-up has a few pics and gives a good general overview.

In our latest PyroElectro tutorial, we show you how to make a basic optical encoder for any mechanical system. Our example setup uses a simple printer pully and motor system. The write-up includes all source code, schematics and parts lists you’d need to build it.

This drop-dead simple project uses a SR87 GPS module and an AVR to understand the data. Then that is output onto a simple 16×2 character LCD. The hardware schematic and software is all there!

This project is probably more novelty than useful, but its simplicity will get you familiar with digital thermometers. A pic is used to interpret output data and a gigantic LCD display is used to show it to us humans. Software and hardware schematics are there just for you!

This quick project shows you how to take I2C output from an Analog Devices temperature sensor and display it on an LCD. All this is done with an ATMega. Not to worry because the software and hardware schematics are provided in the write-up!
