I love it
Is there a schematic of this project please

Kind Regards

Nice idea to have the motor on the gondula. We had 'em on the upper corners of the drawing board. On tip: if the marker is close to the points that the string rotates around the thing becomes much more stable. It still pendels a bit, but it pendels now around the tip of the marker. Also the mathematics gets much simpler.

We endet up using the felt tip pent as the axis itself, attaching the strings to short sections of tube that loosely fit arount the pen. And we used a 3rd tube section to attache a weight, much the same as U did with the bags for the batteries.

Nice work.

Hier a picture:

Please look also at the page of 'Hackerspace FFM':


The page is partly in German, partly in English.
Let me know if U need a help understanding it.


Nice use of the terrible step motors! Atleast, if those are the same motors as mentioned on: http://www.thingiverse.com/thing:18678http://www.thingiverse.com/thi... (28BYJ-48 step motors)

Got any more info about the software used? (I couldn't find anything about it on your site)
