"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 pins."

“In this post we’ll put everything together and show you how to communicate between your Android application and the Arduino using nothing but the Android USB host API. Remember, this approach has nothing to do with Android ADK! Unlike Android ADK, your Android device will act as the USB host, while your Arduino board will act as the USB device.”

“Arturo Vidich, Sofy Yuditskaya and I needed a way to read brains for our Mental Block project last fall. After looking at the options, we decided that hacking a toy EEG would be the cheapest / fastest way to get the data we wanted. Here’s how we did it.”

“A while back, I did a wireless temperature sensor project using XBee radios….So I decided to try the same project using inexpensive RF devices. I used a 434MHz transmitter ($4) and receiver ($5) from Sparkfun, and had great success with these cheap devices. I also used a simple LM34 Fahrenheit temperature sensor, two Arduinos, and a two-digit LED display to show the temperature at the receiver end.”

“If you ever wanted to integrate touch sensitivity into your project, this board could just do the trick. It’s a capacitive touch sensor. These sensors are used in our everyday consumer electronics like notebook trackpads, video game consoles, touchscreens…just to name a few.”

“This is a simple sequencer machine which uses Capacitative Sensing Code for input to the Arduino. It is is a combination drumpad and sequencer. It has just two modes, record, and playback, and needs very few components; an Arduino (of course), and just 3 resistors and a piezo speaker. If you’re feeling decadent, you can add an LED (with a resistor) for more “ooomph”.”

“Most people would just go out and buy a temp / humidity sensor and be done with it….Instead, I decided to build an accurate temp / humidity sensor with a Sensiron SHT11 to read the values, a RBBB Arduino kit to process everything and an Adafruit 128×32 OLED to display the results – all wrapped up in LEGO!”

“In my spare time I have been working on a tiny two axis CNC machine that will be powerful enough to move a pen around like a plotter. Future versions will be larger and handle more powerful tools, but this is a good start to work out the kinks.”
