Never look directly at any laser or its reflection in a mirror.
Never shine it in anyone's eyes, including making a cat chase its image on the floor.
Never shine it into the sky, especially when aircraft are around.

My old XP Dell laptop can draw 300 lines with 300 pixels in each line, in random colours for each pixel, in about 1 second
just using simple BBC BASIC as a speed test. ( Have not yet received a photo cell I have ordered).
If the laser were turret mounted it could spin around 360 degrees instead of oscillating back and forth, line by line
as the Cambridge version does. This will enable very much faster scanning and gives the following.....
A very simple change to the PC software (I am already experimenting on that)) could plot any part of the
rotary output to the photo cell, thereby having any scanned width of picture from 0 to 360 degrees !!
In fact if the frame movement were also 360 degree movable one could scan a complete SPHERE!!
The sync point on the machine can be moved to any 'degree position' to 'tell' the software when to start a new line
One would have to be very careful of ones eyes at 360 as the laser would be scanning a complete circle and up and down
too for each frame. The whole area were you were would be in the laser beam!
ALSO, if the whole contraption were on a hinge it could be moved through 90 degrees to get VERTICAL scanning,
the software simply switched to give verticality on the laptop screen.
So hor/vert scans in any width and any with any number of lines and any heights can be achieved just by
simple changes to the software variables.
Now to speed it all up and add versatile NBTV to my old laptop.
