Hi, I built this last year but thought it may be of some use to others...
It's basically a stand alone PIC based indexer for use with rotary tables, it's pretty cheap - can be put together for 50ukp or so, it outputs step and direction to a suitable controller (I used a cheap controller off eBay - see internal.jpg in pics folder).
I built it to save using index plates and because I don't want to use a fully blown computer for simple indexing.
Written in HiTech C and based on a PIC18F452, source is included for the curious amongst you - please read the document 'legal and instructions.doc' file.
Electronics folder contains a pcb layout and overlay as .bmp files - also a .LYT file for use with Proteus, partslist and circuit diagram.
Pictures folder contains a few images of the completed controller.
Source contains the C files.
In the root there's a keypad template that can be used with the recommended keypad, use instructions and the final .HEX file to program the PIC with.
Hope it's of some use!
Steve.
P.S Should be RotaryTableIndexer.zip attached to this thread
