Principal EE and Electronics consultant in the SF Bay Area. I have done both Conventional Electronic Design and Alternative Energy.Presently I have been doing big-iron, big-physics cancer radiotherapy machines at Viewray/ViewRay Systems. Previously I was a Principal Hardware Electronics Engineer in the Connected Devices group at Fossil. Range of CPUs, chipsets, sensors, power. Component size down to 01005/microBGA/microvia.In the previous few years the emphasis was on LED lighting driver circuits and also some lasers as well as handheld product design and electric vehicle work. Recent work includes kilowatt range in both those last areas. For over three years, I designed and oversaw the production of advanced high-power LED Greenhouse Lights as Manager of Engineering for Lumigrow, Inc. in Novato CA.I additionally have done article and editorial writing in the above areas.My broader work is eclectic because in 25 years I have accumulated varied experience. But it can be summarized as "anything with electronics in it plus greentech". I have built pulse drivers and micropower wearables. For aviation material diagnostics, I built the driver electronics for an LED array that can set your shirt sleeve on fire at a distance of one foot; I cut metal on the plug hybrid shown on the Bush White House website.I have worked on the technical side, but also some on the financial side. With a humanities background, I have verbal skills not always found in an engineer, which can be of use to a law firm in patent work. I can design technology (circuits or systems), advise strategy, give greentech tutelage, perform diligence for investors, or help raise funds. I can also organize an engineering group or technical support team. In my earlier years I personally repaired over 10,000 pcb's/electromech assy's, wrote hundreds of test procedures, and supervised several technician groups.Specialties: Very small microcircuits. Embedded systems. Pulse and waveshaping using fast op amps. Power driver circuits for LED lighting or lasers. Lithium Batteries, vehicles, and solar.Power conversion and Generation.
