Hi,

Came across this stepper motor solution the other day and thought maybe it would be of interest to someone:

http://www.sparkfun.com/products/10025

Seems to have most of the necessary evils:

USB connectivity and shows up as Serial Port to the computer.
2 A4983 1/16th microstepping driver ICs (laser and turntable)
PIC microcontroller with some extra IO pins (laser/light control)

I am not sure but I am guessing someone with the skill could reprogram the PIC to better accommodate their needs in David and maybe save some soldering and wiring headaches.

This does look like a nifty device. It would still require some wiring to hook up the laser and lights but a simpler and relatively cheap solution would likely be a benefit to DAVID.

Looking at it, you possibly wouldn't need to reprogram the PIC because the board comes preloaded with firmware that includes commands for controlling the motors (unless you couldn't move the motors slowly enough). You can even control the motors by typing the commands into a terminal emulator like HyperTerminal. Wouldn't it be great if you could send these commands from inside DAVID (user-defined buttons) and automate them?

These are the commands specific to the EiBotBoard - http://www.schmalzhaus.com/EBB/EBBCommands.html

And these are the general commands for the UBW part - http://www.schmalzhaus.com/UBW/Doc/Firm ... _v145.html
