Senior Design Engineer at Quartzdyne, Inc | A ChampionX Company

It has been a long time since my first electrical engineering job with a small research group who put a fluid physics experiment into space. I was responsible for all the electrical and programming in the group. We met astronauts, touched the space shuttle and visited the birthplace of the Utah and Jarvik artificial hearts. I left that group to work with a mining company. They had constructed a smelter with over 70,000 control points, one of the largest in the world. I viewed it as one giant robot. Over 4 years I worked in varied aspects of this robot from, the control system to field supervisor. I crawled inside of boilers and turbines and designed controllers for a chemical plant that recovered metals. I worked with an aerospace group that was redesigned the guidance system for the Trident Missile (SLBM). I held the most accurate accelerometer that had ever been designed (a device that could measure the earth tide – the response of the ground to the moon). We did analog circuit and test equipment design. I came full circle when I worked for a small R & D company where a typical week could consist of circuit design, PCB layout or assembly, programming, welding, or going to the desert and playing with high explosives. Today, I am the Owner of Celtic Engineering Solutions. We design circuits and PCB’s, write firmware and design custom enclosures to help our customers produce prototypes that lead to products. Growing a business has brought new challenges and new opportunities. The scope of my activities has changed but the goal remains the same, “Provide excellent customer service and detail-oriented design so that my customers succeed.” Check out our weekly newsletter on our website- www.celticengineeringsolutions.com/blog Specialties: Embedded controllers, sensors and actuators, Altium, C, RS232, SPC, optical sensors, PCB Design, Prototyping, 8051 MCU Family, Atmel, Texas Instruments MSP, design, I2C, IoT, Bluetooth, Wi-Fi.
