Encoder and read out

[DaveDoesIT]

Hi,

I have a table that is raised and lowered by a small DC gear-motor and XL belt. I would like to add an encoder to get a read out of numbers so I can position it without having to use a tape measure.

The read out does not have to be inches just numbers will be fine as I can relate a count of say 1245 to 4" etc. When I need it at 4" I can just run it to read a count of 1245. Inches would be nice but not really needed.

Anyone know of a low cost kit that will do this?

Thanks in advance.

Dave

There is a low cost way of doing it with an encoder and any old PC.

The latest link software works good, and I have input the encoder direct, no transistors.

Thanks for that Al, but I would have to reset it to the top or bottom every time I turn on the computer. Also my printer port is in use and I would need another LPT port card.

I think I will go lo-tech and just cut a bit of tape measure off and glue it to a stick. I can get a tape from dollar tree for a buck.
