Doug Coulter recalls that his first engineering/hobby projects used tubes. He has kept up with technological advances ever since as he worked in private and public sectors. Doug has worked as a freelance consultant and writer for the last 20 years. Consulting projects have included process control, prosthetics for the deaf, hearing aids, embedded system and opsys development, CPU design, audio test equipment, telecom equipment development, and DSP development and instruction. Doug lives on a farm in the beautiful Blue Ridge mountains, where he grows much of his own food, generates his own electricity, plays drums, guitar, and keyboards, and runs a digital recording studio.
