Okay, so I finally got the Dinah robot hand sewn in and it is looking pretty good. The fingers could use some tweaking but overall I'm quite happy with how it came out. It's solid and fully articulated.

Here's a photo of it in place:

Now that out of the way, I want to announce I'm officially canceling the Dinah project as far as its current goals and here's why: so basically I was thinking it would be nice to just crank out a working robot using some shortcuts and just do something quick and dirty as a learning experience side quest to get something going. It seemed reasonable at the time. Plus I could pace myself to match the build pace of a fellow roboticist and loosely follow his project's designs. But some things I missed in this decision: #1) I'd be lowering my commitment to excellent quality with no shortcuts - ignoring the adage "do it right the first time" #2) by cutting down on workmanship maxing, I'd be inviting harsh criticism on the new lowered bar of build quality which is the last thing I need when already inviting heavy criticism for a extremely ambitious set of goals to begin with #3) I'd be going against my outspoken commitment to campaign against loud metal gear noise based robots that are completely impractical for home use due to sounding like a construction site #4) it would take away from the focus on my "real" robot projects by creating a "ghetto" side quest robot that could have just been skipped altogether. #5) this would in turn delay me truly solving downgearing by pulleys and actuating the robot arm silently once and for all, proving it can be done and proving that achieving a fully human level DOF human hand and arm while maintaining a human form factor and making all of this silent can and should be done for humanoids.

So is Dinah robot just trash now? No. I still plan to have this project be done, but like Adam, it will be shelved until such a day that the other robots, when ready, complete building these shelved robots for me. And when they are built, it will be using the best methods I have including silent BLDC motors with silent pulley based downgearing. So I'm returning to work on the Abel robot whose arm will build the rest of his own body and then he will build the Adam, Eve, and Dinah robots for me.
