[chbot] Oscilloscope display made from old HDD

[Richard Jones]

Thanks to all who came to last nights meeting.
We spent some time soldering up Mark Athertons laser bar code scanner,
and discussed turning it into a display.
Here is a reference to how to do something similar with an old hard disk drive:

I have a few old drives spare if anyone needs them, and the Warehouse
used to stock $2 laser pointers. You have to ask for them.
