Marblevator "Mini", Bowl Edition

cults3d

WARNING!!!!!! See below. The Marblevator "Mini" is a miniature version of the original Marblevator, with a footprint matching that of a standard business card. Powered by either a single "AA" battery or a 1.5 volt DC power supply, this device is both mobile and mains capable. Shaky video of the prototype can be seen here: https://www.youtube.com/watch?v=YNTQV_7BDw0&list=UUv_zm49u-RjnCJVwhUO-ecA. It's so small that it's hard to maintain focus. Slow motion video study of the final version running at higher speed is available here: https://www.youtube.com/watch?v=TyZAGsszO_0. The video starts out normal speed then progresses to slow motion. A slow motion video study with 14 marbles can be seen here: https://www.youtube.com/watch?v=8Cuei-KCBec. The Marblevator "Mini" comes equipped with replaceable complete tracks, starting with the "Bowl". More tracks are being designed soon. For those who don't mind manual labor, a hand cranked version is available here: http://www.thingiverse.com/thing:310488. Designed using Sketchup 8 and printed in PLA on a Replicator 2 using Makerware 2.3.3.42 "Fine" and "Standard" settings (see instructions), this device has been carefully crafted. As a postscript, the Makerbot credit card shipped with the Replicator 2 was used as a size reference. No endorsement of this thing by Makerbot is intended to be expressed or implied. WARNING!!!!!!! See updates in the instructions regarding the motor. Amazon.com has been sending bad motors. A Polulu replacement is being searched for, and an update will be provided when one is found. Sorry for the inconvenience, and sorry for recommending Amazon.com. Coming soon: https://www.youtube.com/watch?v=RuKmjNzfECM.
