Florin shows us how to convert a Nokia 1110 cell phone’s normal monochrome LCD to a color LCD scrounged from a Nokia 1600. This article does not have much to do with microcontrollers or electronics hobby work but it is interesting and shows that you can hack your cell phones to make them suit your […]

Every wonder what is inside a toll way RFID tag? The windshield on one of our cars had to be replaced the other day. We removed the toll way RFID tag before taking the car to the shop so I could peek inside. I doctored the picture here so the registration number is not shown.

In this article Frank explains the code used in the Wii Nunchuck Mouse article. Each piece of the code is explained clearly. If you want to understand how the Wii Nunchuck Mouse works or learn about programming then this is a good article to read.
Coverage includes the Arduino microcontroller code and the Autoit scripts […]

I did some more scrounging to create a mini Locnar using the LEDs from a Glade Light Show air freshener. The wall wart had previously been scrounged from this air freshener for the bread board power supply. Now we reuse part of the circuit board with the LEDs combined with what we learned in […]

Turns out that a Ping Pong ball makes a reasonable LED diffuser. Just drill a hole and insert the LED. Easy micro Locnar! With an RBG LED this could make a nice system indicator. Maybe build a strip of these indicators to make several status indicators. Each server gets a mini orb to show […]

In this article I describe the simple setup and explain the code to drive analog meters using PWM outputs from an Arduino and the LCD Smartie program. I also replace the meter face to show the proper scale. Replacing the meter scale is very easy to do with most meters and can really add some […]

I just updated the Accelerometer Based Mouse post with a video Bernard sent in. This is an awesome video of him playing a first person shooter game called Dark Messiah. In the video he is moving about and fighting while we watch both his monitor and the mouse. The video is embedded at the bottom […]

A new version of the Arduino board was released with a cool new feature. With help from Paul Badger of Modern Device Company and Brian Riley of the Freeduino project this article will show you how to modify the Arduino Compatible Bare Bones Board to make it compatible with the new Diecimila Arduino. No more […]

This tutorial will show you how to make a very simple robot that will avoid obstacles on the ground. It uses no microcontrollers, no servos, and there is no need to program. The simple design make its an ideal project for those wanting to tryout robotics and also makes a great weekend project. After building […]

Arek combines a wireless router, NAS, and a USB Bit Whacker to take control of his sprinkler system. Reflash the router and NAS with linux, add some PHP and USB controlled phototriacs to the sprinkler controller and control it all from the comfort of your PC.
