Net Power Strip

The Net Power Strip is a cool little project that shows you how to build an electric power strip that you can control via the internet. It uses analog relays for power switching. Hardware schematics included in the project write-up.

Digital Thermometer Display

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!

40W FM Broadcaster

The the 40w fm broadcaster is a very powerful FM range audio amplifier. The project write-up is very detailed with a standard scientific method style. Not for RF novices (but take a look anyway!).

Hardware Temperature Sensor

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!

An Intro To Jacob’s Ladder

The theory behind Jacob's Ladder has been around for quite some time and the project has been reproduced many times in many different ways. This project write-up gives you some background theory and shows a simple implementation of it.

ADC without ADC

Although most modern microcontrollers have ADC's (analog to digital converter) inside of them, you might someday find yourself without one. This little project shows you how to make a simple analog ADC using RC theory.

The &microSCOPE

We've seen quite a few DIY Oscilloscopes and here one more! This one is rather unique in that it as minimal as possible using a 12xxxx series PIC and outputting to a standard TV.

Inside Hot Wheels’ Radar Gun

Hot Wheels makes a cheap radar gun that can actually work to clock the speed of objects. If you've ever been interested in radar this is a great place to start. The circuitry inside is as simple as it gets for radar (which is still fairly complex). Take a look!

Simple Battery Tester

Today's project is an old fashioned one for amateurs and experts: The Battery Tester. It checks to see if the battery has any juice left to power appliances. The design is purely analog so parts are cheap and the tester is very small. Take a look!

Cheap DC Power Supply

This project is a great start for anyone interesting in the world of power electronics. There is nothing too special about the circuit except that it does what it is suppose to and is completely analog. The hardware circuit diagram is in the project write-up along with all details necessary to build this one.
