named because it was about the size of a postage stamp. Programmed in PBASIC, the BASIC Stamp found an audience in electronic hobbyists with powerful I/O commands that made it easy to connect to other electronic components. The Boe-Bot The Boe-Bot is a programmable wheeled robot with a BASIC Stamp 2 brain that is used by educators and hobbyists. After being introduced in 1998, it is one of Parallax's top selling robots. Sensors Parallax manufactures sensors to measure distance, color, humidity, temperature, pressure, RPMs, heat, and altitude. These sensors are either surface-mounted components on a printed circuit board or in packages that are readily acceptable for breadboard-style mounting. Each sensor is supported with educational curriculum and documentation. Education Stamps in Class Launched in 1997, Stamps In Class curriculum was designed to introduce students and educators to BASIC Stamp microcontrollers using software basics, circuit building, and simple hardware. One tutorial in the Stamps in Class series is the Boe-Bot, a simple yet versatile rolling robot that has a BASIC Stamp brain. Propeller education labs The Propeller education program was developed to teach how to operate the Propeller chip. The Propeller features eight 32-bit processors. The Propeller education program demonstrates how to program the microcontroller for use in process control, measurement and signal generation and robotics. The program is designed for engineering students who have product design requirements in their curriculum. Featured in magazines Filling a niche in the technology market by offering robotics for hobbyists, enthusiasts, and students, Parallax has been featured in magazines including: Make Magazine, SERVO Magazine, Robot Magazine, and Nuts and Volts. Unofficial Propeller Expo History The original UPE, the Unofficial Propeller Expo North East (UPENE) was hosted by a long time Parallax Forum member, "Oldbitcollector." He labeled it "Unofficial" so hobbyists could meet and exchange projects, ideas, and advice about Parallax robotics without getting permission to host an "Official Propeller Expo." However, Parallax came on board and now many Parallax employees can be found at each expo, talking with hobbyists, students, and inventors. Unofficial Propeller Expo North East (UPENE) The UPENE was an annual event located in Norwalk, Ohio, at the Norwalk Community Center. The expo consists of educators, engineers, hobbyists and students setting up tables and sharing their experiments, demonstrations, and products based on or inspired by microcontrollers such as the Parallax Propeller. The UPENE was the first of the three existing UPE's. As Parallax unofficially
