I have been a hardware engineer and software developer for over 45 years.
I typically do not develop software as an end product, some Android apps (like BusinessLog) being the exception. Most of my software work is in support of the products I develop and build.
In general terms, I do not do consulting work. I do not sell engineering services. I develop solutions and sell the hardware when at least dozens of boards are required, up to several thousands.
The Waveguide Arc Detectors are part of an on-going product line intended to serve the high power microwave tube transmitter market as often used in commercial and military radar systems.
If you need multiple boards to control something, remotely via radio or not, controlled through an app or not, I may have something for you (email link at the bottom of any page)
