Ask A Question


I can answer questions relating to the control of machines and processes using "Single Board Computers" (SBC). This includes the specification of sensors to detect the state of the machine or process and the development of a program to control the system.

Experience in the area

I am a Physicist with more than 30 years experience in R&D and about 15 years specifically applying SBC to control problems.
