[chbot] Oscilloscope display made from old HDD

[Mark Atherton]

Yes, very good, but I really think hard copy would be a nice extra feature.

So if we used my mate's 50W CO2 laser, we could capture the waveform 
as scorch marks on the living room wall.

I am sure his wife wouldn't mind.

Better run.
