Any new work to report on this? I know you mentioned how you wanted to refine the control mechanism.

Loving the new update. Can't wait to see what you come up with for the control stick.

Just for starters please be aware that I'm an extreme noob to this technology, so go easy on me. Fortunately my local public library will soon open a MakerBot lab ("Sometime this summer..." is what they'll say if you call and ask, "When?!") I'm looking forward to experimenting with little useless doodads, but what I really what to create is a functional Crow T. Robot. This eye mechanism looks interesting, and I plan to print this file, or an updated version, as soon as I'm able -- however, what about the other parts?

Building a crow isn't too hard. Sourcing the parts is the trickiest part.
There are some great sites that have build tips and some that sell the parts or casts of them. The short of it is:

*Body - ebay, you can find the exact name to search for with a bit of digging

*Spine - Lowes/Home Depot, CPVC and PVC pipes that are layered to make the motion system, don't get JUST PVC, CPVC and PVC have different ID and OD that allow them to be layered

*Arms - Amazon! Square ABS tubing is used, check out this link for more: http://www.thingiverse.com/thing:7716

*Eyes, Hockey Mask, Shoulders, Mouth, Hands - Special order from a private vendor. None of these parts have been made since the 70's. You have a better chance of winning the lottery than finding these on eBay or in a thrift store.. There are private vendors who sell cast copies of the originals.

This site is defunct (Don't bother emailing them, I got silence) but shows the build process

This site is still active, and may be worth reaching out to:

And this is a really great forum with build logs etc:

Happy hunting... McCloud!
