The Helitronix Multi-Mixer is a sophisticated, state of the art, electronic mixing device which is now available in two versions, Standard and Special Edition.  The standard version provides mixing capability for radio controlled model helicopters with a single rotor head. This device enables you to add gyros to the pitch and/or roll axis of your helicopter. The Special Edition version adds mixing capabilities for tandem rotor and coaxial rotor helicopters.  The Special Edition mixer can be changed from standard, tandem or coaxial rotor mixing at any time through a simple configuration setting change.

The OpenStompTM Coyote-1 is an open source audio effects processor built for guitar players. With the Coyote-1 users can develop custom audio effects in software (like distortion, echo, chorus etc.), mix multiple effects to build "patches", and exchange those effects and patches with the OpenStompTM community.

At the heart of the Coyote-1 is one the coolest, most innovative, and just plain knock-your-socks-off fun microprocessors to come along in a decade; the Propeller from Parallax. The Propeller contains 8 independent processor cores running simultaneously at 80MHz with a unique architecture supporting a high-level byte coded language called "Spin", and a low-level assembly language with an amazingly versatile instruction set.  
 The Propeller development tools are all free, and the Propeller architecture allows users to develop firmware with nothing more than a simple USB cable. Its revolutionary architecture allows the Propeller to generate video in software by adding just three external resistors, so the Coyote-1 includes a video out port which can be used by developers for debugging or adapted to implement things like graphical tuners, spectrum analyzers, oscilloscopes, or light shows.

The SpinStudio Development System is the buffet style development system. Start with a MainBoard and select from a robust compliment of peripheral modules to configure your board your way! Your system can be reconfigured as your needs change and new SpinStudio modules are developed.

More than 10 different Peripheral Modules are available at this time, there's even a blank ProtoCard for you to design your own module! Some peripheral modules can be used with other Propeller development systems as well, such as the SD memory card adapter and the PropNIC ethernet adapter.

SpinStudio Main Boards and peripheral boards are sold as kits, and assembled by the customer before use. All components are through-hole and spaced for easy soldering.

ViewPort Robot Development Studio: "Build Advanced Robots" mydancebot.com has integrated the components required to build advanced robots into one package.  The ViewPort Robot Development Studio consists of a library of propeller objects and a windows application that reduce programming time while supporting advanced functionality.  The graphical development studio enables you to:

• Tune fuzzy logic rules by analyzing the robot's behavior and state over time.
• Develop and enhance vision algorithms by watching what your robot sees and thinks.
• Improve device communication by measuring digital and analog signals up to 80/40Mhz.

The μOLED-96-PROP is an extremely compact and a cost effective ready to go 'drop in' embedded display module designed by 4D Systems that will deliver ‘stand-alone’ functionality to your project.The module represents a unique combination of a powerful micro controller, the Propeller chip from Parallax Inc, a 0.96” 96x64 pixel 65K full colour OLED display and a micro-SD memory card socket capable of supporting up to 2GB of storage; all in an incredibly tiny 27mm X 23mm package.The module is designed to provide your projects with integrated functionality right out of the box.

The basic idea behind the PropRPM was to make available as many processor resources as possible. Only a few pins are occupied by peripheral components, such as LED bar, RS232 driver and serial EEPROM. If required, even those components can be easily removed, as all parts are on sockets.
