"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."

“Using an add-on card to the already existing avr ethernet board we build a weather station. That is: A weather station with a build-in webserver…The system is modular. You can either build a pure Ethenet weather station or an Ethenet weather station with an additional local LCD display.”

“Clappidoo sits quietly and will not bother anyone, unless somebody carelessly puts an object in front of him. Clappidoo will then wake-up and, depending on his ‘mood’ of the moment, will either be: Angry, Happy, Confused or Flirty. Clappidoo will go trough all these moods at random, and will go back to sleep if you remove the annoyance in front of him.”

“Goals: [1] Create a wireless device that sends data from a simple tilt switch. [2] Use a PC to capture, analyze, and detect shaking mosion…..Method: Place a simple tilt switch on a wireless RF board (PIC12F675). Receive the RF data onto a USB PIC (PIC18F2550). Transmit the data to a laptop using USB serial port emulation (PBP code). Analyze the data using Processing, identify and visualize shake-motion.”

“In order to ease electronical design and increase hardware and software stability EMMA2 is built on top of an off-the-shelf handheld computer with integrated color camera and Bluetooth communication. In addition to the hardware components power supply and motor drive control the undercarriage hosts general purpose I/O interfaces enabling efficient integration of additional sensors in the future.”

“In Yaw Control Part 1 I discussed how gyroscopes can be applied in Radio Controlled cars to reduce yaw under braking and acceleration. Since this first post I have developed an Arduino based yaw control system which goes beyond the original goals to address the major flaw in the gyro based approach.”
