Mike Green - Voted "Most Helpful" Parallax Forums Contributor

Mike Green has been a contributor on the Parallax forums since 2004. He started with amateur radio and electronics as hobbies in his teens, got introduced in college to computers, and learned how to make compilers and operating systems, how computer logic works, and how to debug. He has degrees in Mathematics, Computer Science, and Medicine.  He worked for Datapoint and developed their Pascal compiler as well as helping with operating system and hardware development. Mike is married to a sculptor who occasionally incorporates video, audio, motion, and/or blinking lights in her pieces. Parallax products have been used extensively to do this. Mike has served as technical advisor (and builder) for friends who are sculptors. The Audio Sequencer (described in the Completed Projects forum) is one such project, originally built using a Stamp controller, then redesigned and rebuilt using a Propeller.

Andre' LaMothe - Native Californian, Computer Scientist, Best Selling Author, Entrepreneur. He holds degrees in Mathematics, Computer Science and Electrical Engineering. His career in computing started over a quarter century ago when he began developing video games and he's been hooked ever since! Mr. LaMothe is the former CEO of Xtreme Games LLC a value game developer in the 90's and early 2000's. His current company Nurve Networks LLC designs and develops educational embedded systems and development boards. Andre' has been working with Parallax for a few years now and developed the HYDRA Game Console. LaMothe also teaches at Game Institute and is a professional public speaker. www.xgamestation.com

Tracy Allen has been a contributor on the Parallax forums since 1997, and is a valued friend of Parallax. Tracy Allen received a B.S. in Engineering Physics, and a Ph.D. in Biophysics, both from the University of California at Berkeley. His own research was in bumblebee behavior in relation to the colony's energy needs, and in mathematical modeling. He started EME Systems as a natural adjunct to helping researchers in the biological sciences and in agriculture with instrumentation to gather data in the laboratory and in the field, including the Stache BASIC Stamp Field Programmer and the OWL2pe data logger. He also authored "Earth Measurements" (aka "Applied Sensors") for Parallax's Stamps in Class series of educational student guides using the BASIC Stamp as a tool for teaching environmental monitoring technology to high school and college students. His company, EME Systems has been in business since 1985. Their facility is located in the university town of Berkeley, California, across the bay from San Francisco.

Jeff Ledger- OBC "Old Bit Collector"- Unofficial Propeller Expo

Jeff Ledger has been a major contributor to the Propeller and has been very active on the Parallax forums as Oldbitcollector. Jeff is a career technologist with 30 years experience in the computer industry. His fondness for the early days of microcomputers brought the Propeller to his radar when a C64 emulation project using the Propeller was announced on the Parallax forums. Jeff is responsible for organizing and directing the unofficial Propeller Expos. The 2009 expos take place in Rocklin, CA at Parallax in June and in Norwalk, OH at the Norwalk Community Center in August. In 2008 Jeff held the first expo in Ohio. It was a success with over 100 attendees. When not working on the next Propeller Expo, his interests in the Propeller revolve primarily around using the chip as a "retro" style microcomputer. He has been involved in many related software projects to this end. Projects include PropDOS, CoggyTerm, and many others.

Phil Pilgrim's interest in electronics began with ham radio as a teen and continued with degrees in physics (WittenbergUniversity) and computer science (University of Michigan). The first contact between his current company (Bueno Systems) and Parallax came with a purchase of the PIC programmer and assembler software, which were employed to develop a linescan inspection system using a TI (soon to be spun off as TAOS) linear array sensor. The advent of the SX and Parallax's SX Key made possible a serendipitous combination with another TAOS imaging sensor, which he incorporated into an evaluation module. Meanwhile, Phi's relationship with TAOS brought him into separate contact with Parallax, this time as a designer of the TCS230 color sensor module. Since then he has designed several other products for Parallax, including the MoBoStamp-pe and its daughterboards, the SoundPAL, ServoPAL, and BOE-Bot Encoder Kit, among others. The Propeller has now captured a large chunk of his attention and he's enjoying some new design work based upon it.

Hanno Sander - Viewport Creator and Open Source Contributor

Hanno Sander has been working with computers since he programmed a lunar lander game for the z80 when he was 6. Since then he graduated from Stanford University with a degree in Computer Science and then started his corporate career as an internet entrepreneur. He moved to New Zealand in 2005 to spend time with his family and develop sophisticated, yet affordable robots starting with the DanceBot. He created Viewport software, the premier debugging environment for the Propeller. His technical interests include computer vision, embedded systems, industrial control, control theory, parallel computing and fuzzy logic. http://www.mydancebot.com 

Jon Williams - Engineer & Author (Nuts & Volts Columns)

Jon Williams is a Los Angeles based actor (see www.jonmcphalen.com), writer, (StampWorks book, “Stamp Applications” column in Nuts & Volts magazine), and engineer. Jon got his start in embedded programming back in 1994 with the original BASIC Stamp 1 and quickly became a “go-to” guy for BASIC Stamp solutions; it wasn’t long before he was developing commercial applications using the BASIC Stamp 1 and BASIC Stamp 2. After working for Parallax as an application engineer he co-founded EFX-TEK, an electronics company that focuses on entertainment applications (movie FX, theme parks, museums, Halloween industry). Jon continues to write his very popular column in Nuts & Volts magazine and is our on-camera talent in the Parallax Perspective product videos.
