Injection Molded and Thermoformed Yoyo
2.008 Yoyo project (ongoing work in progress, Fall 2011)

Preliminary CAD design

Nyancat Paperweight
MasterCAM with EZTrak CNC Mill.
Hexa-rideable-pod

Summer 2011 Manufacturing Exercise (done for fun).
Based off of an existing design found online.

Details
Mechanical
  • Frame welded together from 1'' and 1''x2'' square steel stock (MIG welding, horizontal bandsaw, milling out 1/2'' and 3/4'' holes with step drill)
  • Bolts and nuts from McMaster
  • 2x wheelchair motors (ebay)
Electrical
  • Powered by A123 12V lead-acid replacements
  • Arduino used to process two foot pedal potentiometers and a switch for forwards/backwards (eventually will move to joystick + analog circuit)
  • 2x Victor motor controllers (PWM input)
  • FRC kill switch

In-progress at MITERS
First outside test, 8/23/11
@ NYC Maker Faire 2011. http://www.youtube.com/watch?v=OOLkBiJ0wKQ&t=1m1s
Video taken by Shane Colton (yay thanks!).

Todo, 10/17/11:

  • replace wooden feet with tennis balls
  • make analog circuit / make enclosure for electronics
  • build motor controller (get rid of victors, overkill for my use)
Hexa-dancing-pod
Details
Mechanical
  • Frame hand-cut out of ABS plastic (vertical bandsaw)
  • 18 servos, 6x VS-2 and  12x HTC-311s
Electrical
  • Arduino nano as main processor (on 2.007 carrier board)
  • No sensors yet
Software
Please mute sound if you watch this video -- lots of background noise.
Retroactive CAD in Solidworks.
Completed prototype, 
@ Cambridge Maker Faire 2011. Bottom-most is a small linkage-style hexapod prototype.

Todo, 10/17/11:

  • Write software for dancing
  • Laser-cut a new frame (acrylic or balsa wood) (Invest in newer, more powerful servos?)
  • Add sensors
Laser-cut Clock Face
Cut from 3 sheets of acrylic on the lasercutter, glued together with careful application around the edges of contact cement.
