Gerald Rigdon
I'm a R&D engineer, software developer, entrepreneur, author, technology, blockchain, and cybersecurity enthusiast, and former minister (no doubt a surprise to post Y2K associates).
My computer science education was non-traditional. I did a 2-year program in computer science, spent a decade in industry, then returned to get a bachelors, and subsequently two more graduate degrees.
In 35 years of engineering I've covered a lot of bases: Electronics, Embedded Safety Critical Systems, SQL and Databases, Test Systems, Manufacturing Stations, Desktop, Mobile, Web, and recently Blockchain Applications.
My entrepreneurial endeavors started circa 1986 when I wrote a cutting edge Bible Translation PC Application pre-Microsoft Windows. Ten years later I had built my first commercial project which I did from A-Z...the electronics, mechanical & assembly, firmware, desktop application, sales & marketing. More recent endeavors have included building an e-commerce air purifier store.
As an author I've published a novel and penned an award winning screenplay. I've also written a few technical White Papers, and published a training course on the Medical Device Software Process.
I have a keen interest in various technology subject matter and actively work on personal hobby projects.
During my time in the ministry I spent many years immersed in Biblical studies including New Testament Greek. I preached numerous sermons to audiences ranging in size from hundreds to thousands but stepped aside from the public ministry in 1998.
Finally, I'm the proud father of 2 wonderful boys.

Corporate Experience
Medical Devices
Advisory and development role that includes Class III implantable design, solving difficult technical issues across multiple projects, oversight of safety critical software design patterns and static analysis techniques.
Pacemakers, Defibrillators, Diagnostic Recorders, Research Controls
Dynamically Stabilized Balancing Machines
Original member of the product development team of a highly visible startup company that created the world’s first commercially available dynamically stabilized balancing machine, namely, the Segway Personal Transporter. Enjoyed a wide variety of work experiences from upstream prototype concept creation, to product development and release, to downstream manufacturing and serviceability tools, as well as leading investigations for issues in fielded products and subsequent software maintenance releases.

Entrepreneurial
- In 2020 my partner and I built and launched an online air purifier store. -> View Store
This project required learning not only new web technologies but also various air purification technologies. Much of the work has included writing technical content and numerous ongoing blogs about air purifiers.
- In 1995-1996 I designed and built a PID Control Loop Product for teaching control theory.
It was a tutorial built around a real physical system that housed a feedback loop using a custom circuit board with an 8051 micro that drove a DC motor and potentiometer. It connected to a PC Windows Application via an RS-232 serial port.
With the PC interface the system doubled as a real PID controller with an input port and both a 0-10v and 4-20ma output signal for complete closed loop control of a process.
- During the years from 1986-1987 I created a Bible Translation software product built on MS-DOS.
Below is a small sample of the original text, in the Roman alphabet in ASCII codes, created by a UBS/Academic research project. It’s the Gospel of John chapter 1 verse 1:
_1.1 *)EN
Word for word English would be: "In beginning was the Logos, and the Logos was toward the God, and God was the Logos."
My translation software coverted that text and displayed the output in Biblical Greek using custom digitized fonts and had full interlinear capability.
That was groundbreaking at the time.
In native Greek it would be: Ἐν ἀρχῇ ἦν ὁ λόγος, καὶ ὁ λόγος ἦν πρὸς τὸν θεόν, καὶ θεὸς ἦν ὁ λόγος. – Westcott/Hort
It’s amazing how easy it is to display it in Greek today. The above is a quick copy and paste. Not so in 1986!
