guts came from an EPSON 1250 Scanner (a referb unit ..) 80$cnd
which uses a LM9832 'scanner-on-a-chip'  with a USB interface
and a 10000 * 3 element sensor

software is part of the plustek driver from the SANE project

platform is the top plate off a old FH scsi drive with the motor
that drove the platters is the main spindle
(very smooth bearings & conveniently attached to a platform)
note: rubber band & duct-tape spindle drive

on the platform to the left is the motor drive from the scanner
the USB interface is in the foreground -- the actual scanner 'chip'
& sensor assembly is the green board stuck out of the grey box ...
