A simple project that uses a recycled stepper. One of the many in our junk ! Here's the Fritzing component I made for this project: the M35SP-7N.

Recycled from a Boeder Smart Scan slim edition http://saopaulo.fechoo.com.br/fotos/32198_1.jpg

The motor is a mitsumi 7N variant http://pdf1.alldatasheet.com/datasheet-pdf/view/176481/MITSUMI/M35SP-7.html

The piece was recovered by VerdeBinario Museum/Lab (http://www.verdebinario.org)

enjoy !
