Pulse Motor Schematic Diagram and component list
Click on image above for a bigger picture of the Schema. Updated 18/03/2007
I have posted this circuit to the Over Unity Forums
http://www.overunity.com/index.php/topic,2071.new.html#new and am waiting
for feedback on the circuit before etching the first Prototype PCB, but meanwhile
I will be working on the Firmware and Windows Software.
Component List
Most of the components are from
http://www.rapidonline.com
The Max233 and Pic16F876 are from RS
Components, but if you search around you will get them cheaper
