I still have an old SVS scanner set with the directions! What holy crap. It was my first actual laser scanner. Had speakers and mirrors before that and a hene I killed off on a HENE 12kv transformer. Was fun watching it arc over. I was only 12 at the time. Fire was good. Little red dot was boring. This was about the same age my friends and I would launch my sisters barbie over the house on a D rocket engine. Flew amazingly straight with a stick attached.
