Well... I haven't always been a paramedic. I've studied Biochemistry and one part of the curiculum involved basic electronics, math, physics and Analogue/Digital signal processing for Laboratory puposes. This in combination with me being a 'wingnut' and a portion of stamina enabled me to start building my project.
Ofcours I didn't invented all the stuff myself. I contact other builders on regular basis. Each one of us has his own skills, ideas and inventions. Together we help each other out providing eachother with critical notes, hints andf tips.
And nowadays the internet supplies us with lots of technical websites, pictures, etc. So contacting experts with valuable knowledge like you guys is easier then ever.
