The Hemiphterograaf is live!
Thanks to a bunch*, we achieved our goal in being able to control the penholder.
We can send serial commands to the arduino.
Connected to the arduino are the dual h-bridge chips. They each control a steppermotor.
It is a first step, but we managed it in 1,5 days.

project costs: ± € 120,- (complete list available later)
*Thanks to the code repository’s of similar open source projects & Mark who shared his crib for the purpose of tinkerdays 2012. Goodnight for now. We’ll do our best to update the program code in the “code” section of the blog as well as any kind of tutorial for those who want certain “features” of the hemiphterograaf clarified.

We have kept our cool and catched the bugs
