History

Originally established in 1987, in Rocklin, California, Parallax Inc. manufactured products such as the ISEPIC, TopRAM, and the first third-party Microchip PIC Programmer. In 1992, the BASIC Stamp 1 microcontroller module was released. In 1995, the BASIC Stamp 2 module was added to the product lineup. By 2002, there were over three million BASIC Stamp microcontrollers in use around the world. In 1997, the Stamps in Class program was created to provide educational resources that addressed the needs of electronic students ages 14 and up. The Boe-Bot is one of the company’s most popular products in the educational program. In 1998, Parallax Inc. formed a partnership with

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.

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.

The Parallax forum

Before 2004, the Parallax product user support forum was hosted in Yahoo! Discussion Groups. In 2004, this discussion group was moved from Yahoo! to Parallax Forums, located through Parallax's website. Members frequently discuss projects, programming, and products designed around the BASIC Stamp and Propeller Chip. Also, students can use the forums as a place to ask questions and receive direction to solve homework and projects.
