Mechanical QCW !!
« on: March 15, 2019, 08:33:23 AM »
By profession I was mechanical rather than electronic so I tend to think
in this way and like mechanical solutions.

I am building my first QCW and wondered about generating the sloping
waveform normally derived from a ATtiny for the bus voltage.

So I rigged up a small DC motor running at about 6000 RPM which is
10 milli sec per rev. This can be reduced to give 20 milli sec etc

Mounted on this is a small cardboard (!) cam on either side of which is an led and  light detector.

Wih a suitable shape to the cam the output shown on my scope is the
wave form required !
It's not quite right at present as the cam profile needs slightly tweeking.

So that's  my mechanical QCW !

That really reminds me of the simplicity and beauty of mechanical computers, if you do not know this series of videos, they are definitely worth a watch!

Why its split into 7 parts is beyond me, but here it all is!
