Embedded LinuxR. Hardware, Software, and Interfacing

Craig Hollabaugh has been fascinated by electronics since he bought an AM radio in elementary school. He was first exposed to Unix during a cross-country talk session in 1985. Later, he administered networked Sun and DEC workstations while pursuing a doctoral degree in electrical engineering at Georgia Institute of Technology.

Craig's first embedded SCADA (supervisory control and data acquisition) design, the PacMeister, remotely monitored the gasoline additive injection process and earned him a U.S. patent. His next embedded design, the Titan PAC-3, based on Intel x86 architecture, controlled this injection process, using a home-growth multitasking operating system written in C++, complete with boot code, communications ability, and field-downloadable application code.

In 1995 Craig co-founded Wireless Scientific, where he developed 20 spread- spectrum 900MHz ISM industrial telemetry products. Craig worked with more than 200 developers, systems integrators, and equipment manufacturers to incorporate wireless telemetry within their SCADA applications or product lines. In 1996 Wireless Scientific's Global Data Management project used Linux as a development platform to remotely monitor and control additive tank levels.

In 1997 Lanier Corporation charged Craig with architecting its next-generation VoiceWriter, a medical digital dictation and transcription system with revenues beyond $100 million. His responsibilities included ensuring that product development followed current/future technological trends, adhered to technical/medical information standards, and incorporated Lanier's legacy products.

Craig consults from his home in Ouray, Colorado. He developed the firmware for Antec's flagship cable distribution product, the Proteus Scalable Node. At Clifton, Weiss and Associates, Craig is a member of a carrier-class telecommunications network design team. His current responsibilities involve designing and analyzing wired and wireless voice and data networks for Dallas Area Rapid Transit, Metro North Railroad, New York City Transit, and Pittsburgh Area Transit. He's also designing FM, MP3, and Bluetooth headset electronics for Arriva.

The Ouray community benefits through Craig's system administration support of Ouraynet and his adult education classes in electronics and programming. Most recently, Craig co-founded The Silverjack Baking Company, where he will bake and sell scrumptious delights from a horse-drawn bakery wagon on Ouray's Main Street during the summer months. If there's snow flying, you'll most likely find him snowboarding at Telluride.
