I have put the T-Rex Toy back together and tested out function of the servos. They are moving as expected, but unfortunately the friction in the leg-joints is causing the whole legs to move erratically.
It was either the friction or a protocol error during testing, but one of the leg servos blew. So next step would be to completely cut out the legs and replace the plastic on plastic friction joint with a ball bearing. I didn't want to do this unless its necessary and apparently I have no choice, I will need to replace the servo anyway so I might as well.
The jaw movement is promising, I took an animation I was planning to use on a bigger jaw and tried it out with this one.. the leg movement helped give the whole model live until one of them died, but its still nice to see some movement at all. It was however rather frustrating trying to get the serial protocol timing to sync up with the sound, apparently I will need to find or program a tool that will allow me to send out telegrams with an exact timing.
So anyway here is a picture and video of what he looks like when singing.

Thats awesome! The jaw has such a precise motor. Must have taken a hell of a long time to sync the movement!
That depends, compared to how long lipsync usually takes me this went rather fast, I actually captured the jaw movement by holding the mouse to my chin, of course I had to edit it, but it helped me a lot nonetheless. Just need to finish the remaining 2/3 of the song.
