"Hobbyist" is a good excluder for power stations, spaceships, solar
arrays that cover a whole desert, etc whilst still including PSUs,
amateur rocketry, domestic solar panels and installations etc

[EE] topics could still include discussion of techniques used in large
scale or specialised professional projects (for example sensors - 
gyros, A2D, temperature etc - and sensor protection or environment)
that are of **practical** use to the hobbyist and professional designer
and constructor
