Homebrew PCBs

I guess it depends on the age of the boys and the price of their

Lasers are one of my hobbies, or at least they used to be. The lasers 
I used were either made by me or found on a scrap heap and repaired 
by me.

But you are correct, it is beyond most hobbyists abilities. I was 
just trying to be helpful to the ones who can get access to the laser 
type hobbies.
