  • Chicken Using Coop Boss

    It was the first warm evening of spring and I just sat down to watch TV after dinner.  I picked up my iPad and tapped the link to our chicken coop’s web cam.  Instead of the usual bobbing heads of sleeping chickens I only saw one chicken and noticed the coop’s floor was covered with feathers.

  • Prospero: The Robot Farmer

    Prospero is the working prototype of an Autonomous Micro Planter (AMP) that uses a combination of swarm and game theory to make planting decisions plant by plant. The robot is designed to operate as a swarm and is the first of four developmental steps.

  • TheraPlay 2.0: Creating an Engaging Robotic Platform for Dyssemic and Autistic (ASD) Children

    Dyssemic (socially-challenged) is a term that refers to kids that have trouble communicating their ideas with other people and expressing themselves in general. Autism is a subset of dyssemia and is considered a spectrum disorder, meaning that each child has different characteristics in the way autism affects them.

  • Figure from The Propeller Experiment Controller Paper

    I am doctoral student studying behavior analysis and comparative psychology at Oklahoma State University in the laboratory of Dr. Charles I. Abramson. To be brief, I study basic principles of learning common to many species, including humans. I use the Parallax Propeller Microcontroller in my research.

  • RoboThespian

    RoboThespian is fully programmable with a web based interface and the API is available to developers.

  • Triage Training System creator David Dorhout and friend Michah holding the "Acting Coach" and "Director's Tablet.".

    The Triage Training System (TTS) provides a simple, mobile way to dynamically manage large groups of “victims” in a mass injury simulation by providing individual instructions on how each “victim” should act based on their unique injury. The TTS also simulates life signs such as a pulse.

  • Dr. Singh with his Wireless Vineyard Monitor.

    The Vineyard Monitor is shown below. It consists of a weatherproof box that houses the electronics mounted on a PVC support pipe. The pipe is intended to be driven into the ground. The soil temperature is measured by a sensor located at the bottom of the pipe.

  • Harrison and the Thumper.

    Thumper is a Propeller based Internet Radio Player with MP3 Recording and Playback capabilities. The hardware contains a single Parallax Propeller Chip and some external support chips to implement a complete internet radio player.

  • The Grizwold FX Rudoph 16 Control Board

    I would like to submit my propeller powered Christmas lights project that has been ongoing for the past few years. The lights are controlled by a 16 channel Propeller powered controller that I call the "Rudolph 16". These controllers receive DMX-512 from a Propeller powered PC interface I call the "DMX Director".

  • Eric Moyer with the OpenStomp

    The Coyote-1 is a user programmable/configurable open source audio effects processor designed primarily for guitar players. The Coyote-1 is currently capable of producing Echo, Distortion, Tremolo, Chorus, and Pitch Dive effects, and can be extended to produce hundreds of other audio effects through the creation of custom “effect modules.”

  • Cardiac Simulator Closed

    By day, I am a cardiovascular surgery nurse and by night I am an electronics learner and tinkerer.  I decided to combine both of my loves into one project – a cardiac simulator.  It is my hope that it will become a good resource for both healthcare givers as well as patients.  Healthcare givers can use the cardiac simulator as an

  • The OughtToPilot project.

    A Propeller-based attitude estimation device embeddable into low cost remote control (RC) airplanes for hobby-grade UAV application is presented. The system senses and controls the aircraft’s attitude (pitch and roll) to maintain level flight and guides the aircraft toward a pre-loaded GPS waypoint.

  • Close up of front of Propeller Clock PBC.

    Here is my entry to the "Hack the Halls!" contest. I started making this out for my brother and when I saw the contest I figured I'll post and see how I do. Check out the video:

  • Ryan and the DAQPac board.

    DAQPac is an automotive data logger designed from the ground up for motorsports enthusiasts. It has all the features necessary for a driver to improve both their skill and vehicle performance. DAQPac was the result of two prior prototypes, each one evaluating the hardware for function at a reasonable cost.
