Hey all, I'm looking at finding some less expensive substitutions for the servos specified in the project. Have found some but am looking to see if specifications match. Will post later today.
Here are the lower cost servos I found with specs and price at Tower Hobbies from a company called RC Gearshop. I wouldn't use them for a Mission Critical project, but they look fine for the class. Any thoughts?
For my personal projects I stick to servos with metal gears, and have recently started working primarily with digital servos which have a lot of great features like being able to define limits, moment direction, etc. on each servo. But they do cost a bit more!
I'm sure you could find plenty of good uses for inexpensive servos like those though! Especially if you needed a large number of servos to move relatively low weight features.
Hobbyking has their own range of servo's that I have found quite good. And the price is very good too. Since I use a microcontroller to handle my servo's I can program in the limiters.
David, The servos you found look a lot like the Win-King servos I purchased for the class. I really like the prices. Chris, I almost always use animatronics software for my projects and set the limits there. See you all this afternoon (or morning!).
I use VSA by Brookshire Software. Have been using it for about 10 years. I really like it. For the servo driver board I used to use a board by Scott Edwards. I switched to boards by pololu.com. If you have questions, let me know.
I run several 3 axis skulls in my haunt that incorporate random movements. They use a custom board to provide the random tilt, rotate and nod motions as well as the audio to jaw sync circuit. It works great as long as you don't need specific, programmed movements.

Very nice controllers (but a bit more pricy) are the ones made by Gilderfluke. They have their own software, that you can use for free to program up to 15 or 16 servos with. I built my own controller using two 4-function joysticks to do the programming. I used one of them on this guy (animatronic not built by me, I just rebuilt the controls) https://www.youtube.com/watch?v=eS4MOY57V4E
