Dennis more info?

One of my current side projects is to prep my Alfa for sale.

That there is a 3D printed plastic skeleton, with feathers made of carbon fiber, fiberglass and a bit of foamboard core material, strung together with elastic and thread. Modeled off of a Canada goose wing from the garbage can of a kind hunter

Honestly it baffles me that I seem to be the only person working on this. Humans have been fascinated by bird flight forever, and the necessary materials to directly copy their design have been available for a while now. It kind of feels like cheating, because mother nature has already done the really hard part of aerodynamic optimization/finding the optimal joint angles/feather shapes/etc. And even given us a zillion variations to show how different changes affect the performance.

I'll soon be building another wing with all the fixes to problems I encountered making that one. For one thing, the joint angles aren't quite right. For another, it takes some coaxing to get it folded now, since the small feathers keep cutting into the edges of the large ones and vice versa. Notice the two small ones in the middle with dark edges. That was my test to see if tracing around the edge with a strip of carbon fiber would eliminate the rough snaggy edges of plain woven fiberglass, and it appears to work.

The next wing will also feature a new shoulder mechanism, which enables humerus twist motion in addition to forward-back motion. Here's a short video of the experimental version, along with an experimental sensor glove to control it: https://www.youtube.com/watch?v=EoIBsBOmWLc
Those servos sound pretty miserable though The final version will use leadscrews, which hold their position without power. Here's what the mechanism looks like inside:
And then that whole kaboodle will be rotated by the main flapping actuator.

Do you have your vet's approval to expose Jake to that sort of thing at such a tender age? I seem to recall there were some studies on early childhood banjo exposure that suggested lifetime addiction was not usual, with the sort of social ostracism associated with that sort of behavior. I cannot imagine that Jake differs that much from the average rambunctious 2 year old, so perhaps a canine vaccination or some sort of operant avoidance conditioning?
