David is known for his work in the documentary series "The Secret of Skin-Walker Ranch" and the documentary movie "A Tear in the Sky". David's inventions and re-engineered FLIR thermal cameras were used at Skin-Walker Ranch offering new functions which are not commercially available. His inventions detected highly unusual phenomena in a series of controlled documented scientific experiments. In the movie A Tear in the Sky he worked as a science and technology researcher and analyst. He also supplied and calibrated all of the FLIR thermal cameras, inventions, and a large array of equipment that were used in the documentary movie. At the age of five his parents gave him a soldering iron and he showed his electronic projects to his kindergarten class. He developed an interest in astronomy and by age 10 he built a small Newtonian telescope using plumbing parts. He began playing guitar and at age 14 he was building Marshall tube guitar amplifiers while changing the circuit for custom overdrive sounds. At age 22 he was employed as an electronic engineer at Nye Viking, a Ham radio product manufacturer, where he designed electronic circuits for RF power monitors and wrote the metrology manuals for the calibration procedures of his designs. He started his own private electronic engineering consulting business and engineered and built a vector impedance oscilloscope that fits in the palm of the hand. He co-founded an electronic test and measurement equipment custom engineering and supply corporation where he contracts with the US government, aerospace, and industrial sectors. He continues to develop new technology that is focused on detecting unknown aerial phenomena and paranormal activity. In his spare time, he volunteers at Bellevue College maintaining and calibrating the astronomical observatory. His other interests include solo finger-style acoustic guitar composition and recording, audio Hi-Fi amplifier and loudspeaker cone, and voice-coil engineering, consulting with pro audio product manufacturers, consulting with organizations researching the UFO/ UAP and paranormal phenomena, volunteering with astronomy clubs, astrophotography, mineral prospecting using Gamma radiation detection and enjoying his collection of exotic sports cars.
