DIY Weather Station

September 1, 2010 by Chris
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!

3 Digits Digital Volt Meter

August 27, 2010 by Chris
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!

A 4 bit CPU from TTL ICs

August 26, 2010 by Chris
It's not even close to an analog computer, yet it reminds me so much of them. This computer is built purely from TTL counters. The instructions are stored in two EEPROMs and the old school style is definitely worth a look. The write-up gives you a great idea of why we love microcontrollers so much.

Alarm Motion Sensor Switch

August 24, 2010 by Chris
I'm sure we've all seen the security motion sensors in the corner of the walls of our arch-enemies' homes, so why not learn how it works? This project takes a look at how to use a PIR motion sensor to switch on/off virtually anything, from an alarm to water sprinklers!

120V LED Night Light

August 23, 2010 by Chris
While it might seem to be a terribly obvious design, a night light that runs off of AC 120v is still worth taking a look at. The circuit, construction, pcb board & layout are all in the project write-up. Make one for your child today!

Using an AVR as an RFID tag

August 20, 2010 by Chris
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.

Network Controlled Air Conditioner

August 19, 2010 by Chris
This project uses a small embedded board to gain computer control over an old school air conditioner. The write-up goes through the process of hacking the A/C board and making php scripts to control it. There's even a short youtube video to sum it all up!

Z80 Text Scroller

October 1, 2009 by Chris
While surfing around I ran across the Z80 Text Scroller by Tim Williams. Tim's website has a lot of his personal projects and they all have the DIY feel that I love. Take a look at the text scroller and his site, hardware schematics & software are there as well!

Mint Tin Bike Light

September 29, 2009 by Chris
This project uses a 12xx series PIC to control the rear light to go on a bicycle. The main function is for when you are riding your bike at night so people can see you. Hardware schematics, PCB layout & software is all there. Avid bicyclists don't miss this one!
