I happen to use some of the quick setting JBweld today. I misspoke,
it is not clear, grayish and black for the two parts. It may be just
carbon black but who knows.
Almost every hardware store has Devcon products, slow setting and fast.
At least some are clear. Sorry for the confusion. IIRC

I followed this series of emails.
That's why back in the 80's when Light Machines designed the ProLight 2000 they
used an Animatics servo control box equipped to run 3 or four axes. All the

Hi Peter;
Working on my encoder, I have a 5 to 1 signal attenuation according the

of a curved piece of alu was rotted by the 0w20 oil I use in the bronze

my understanding is that most sin/cos are many lines per rev. It's just
that they are fancier lines than an encoder made for incremental output.
The index marker is one line per rev.

Just to add to the mix, I have done this with an Arduino.
In my application I was also generating the excitation voltage for a
resolver, so it was a little more involved.
Fundamentally it is two

A sin and cos are 90 degrees apart. All you should need to do is threshold
the signal and you have A/B quadrature.Many ways to threshold it but
you want the one with least noise.
A simple way to convert a sin wave to a square wave is to amplify then clip
it with diodes. A comparator can

Check the max frequency on any encoder you look at. The inexpensive ones
max out at 200 K. Frequency is not a problem is you want to throw $$ at
it. It is very hard to win; lots of counts at the high end but not many
when you are creeping. There just ain't no free lunch.

I think the 5v are newer than the ones I have researched in the past.
Don't they have a converter card for ttl/quadrature? They certainly do for
the older types. People seem to have used the TIDA-00178 converter board.

You care where the loop are because if they are in your PC you need a

Special PC? Pretty much any PC will work. I guess you could call the OS
special but not nearly as special as an RTOS on an external processor.
