There is no fly back to the next line either, so it may'read'
each alternate line left to right, then right to left !!
This Uni has about 10 scientific Lego projects
which are all very impressive.
I daresay engineering students going to Cambridge Uni never thought that they would be
involved with Lego from their childhood days!

I have been nosing around. Found that an old laptop running BBC BASIC,
all the colours can be intensity controlled, unlike on the old BBC micro.
So that would enable me to write a modulated scanning display app, probably in
faster assembly language, which I can do.
Old laptops have the parallel port which can be used to
input from the photocell so I understand.
All I require now are a huge pile of Lego pieces !!
It might be an interesting project to see an image forming on the screen
as the laser pen scans and lights up the subject in a darkened room.
Maybe capture all the still images then fast present them for movement !!
I might ask Father Xmas to send me a big Lego set soon.

The input to the laptop from the photo cell will be 8 bit.
If one ensured that the intensity never reached 255 (max 8 bit), but 254
one could exclusively use 255 as sync signal.
Also first bit alone (one) tooo.
So two sync possibilities in just 8 bits!
I must be mad. I have ordered a big bag of Lego on eBay. I AM mad.
The noughts and crosses mAchine, as with much other stuff,
is on the back burner.

So i am thinking you are using the computer as a monitor you could do away with camera for now and replace it with a video sync signals to test ?
