Halloween 2016 - Baby Dolls

To the thrift store for two slightly used dolls - can't beat 40 and 80 cents.

So sorry little gal but you need Red LED eyes!!



I never used servo's before - but found 5 sets of these cheep 28BYJ-48 Stepper Motor's for $12.68

I searched Thingiverse for a pulley created with openSCAD that had the stepper connection and quickly modified it as I don't need the V-groove (thing:913582). I screwed it directly to the gals head.


Looking good!

Next wire management - as I want the head to speed without twisting the wires. Searches on the webs came up empty with slip-rings that would fit my needs so - I designed my own thing:1824060 ;-)

I had issues getting power through the bearing so I popped off the dust cap and cleaned with wd-40 to flush out the grease.

   






Works great - well until the gal's stuffing gets wound out inside the bearing because it's missing the dust cap!

Next up is sound with this $9.99 MP3 Player with the help of this wikigit code and free Poltergeist MP3 we are good to go.
