		<title>Wireless Robotics Platform: Cheap R/C Vehicle + Arduino + XBee + Processing</title>
		<description><![CDATA[I built a wireless robotics platform from a cheap R/C car, an Arduino with XBee shield, small microswitch sensors, and a Processing program running on a remote computer to control the vehicle.  The vehicle is completely controlled by the code running on the remote computer which allows very rapid prototyping of the code to [...]]]></description>

		<title>EZ-Expander Shield for Arduino</title>
		<description><![CDATA[I&#8217;m happy to finally announce my new product, the EZ-Expander shield.  After several months of hard work of sourcing parts, designing the PCB, and setting up a store, my first product is now available for purchase in the nootropic design store! 
For all the technical details, go to the EZ-Expander page.

		<title>Arduino Police Lights</title>
		<description><![CDATA[This is an amusing project inspired by flashing blue and red lights on police cars, ambulances, etc.  This is a perf board Arduino with 5 blue and 5 red LEDs, and the Arduino code lights them up in a pattern similar to police lights.
First, the Arduino built on a perf board.  It&#8217;s not hard to [...]]]></description>

		<title>Arduino-Controlled Lock with Keypad</title>
		<description><![CDATA[After tearing down an old CD player, I was inspired by the CD laser scanning assembly to build a door lock for my subterranean lab.  The assembly has two motors: one for turning the CD (I&#8217;m not using this one) and one for slowly moving the laser across the CD&#8217;s surface.  This second [...]]]></description>

		<title>Wireless Temperature Sensor</title>
		<description><![CDATA[I decided to explore the more advanced features of XBee radios by building a remote temperature sensor.  You can get quite a bit of control over an XBee radio without a microcontroller at all.  You can configure the radio to send sensor readings at particular intervals when it detects changes on certain input [...]]]></description>

		<title>Hack-a-Sketch</title>
		<description><![CDATA[Here is a device I call the Hack-a-Sketch.  The screen is a normal laptop (an old one), but it has real knobs which control the stylus on the screen.
An Arduino board reads the inputs from two potentiometers (the knobs), and sends the information via USB to a Processing sketch which displays the path of [...]]]></description>

		<title>LED Clock</title>
		<description><![CDATA[I harvested this LED clock display from an ancient VCR and wrote an Arduino sketch to drive the display.  First I experimented with the leads to understand which leads controlled what behavior.  There are 4 digits on the display and there are 4 corresponding leads for positive voltage to drive them (the Arduino [...]]]></description>
