Gearing up two cims?

In all seriousness, Its what we used in Robot in 3 days. Worked fantastically.

Hey Andrew,

Since you're reading this thread, maybe you could give a definitive answer to a question that's been bouncing around:

What CIM operating speed did you finally settle on for your shooter, and what speed control algorithm did you use?

I'd have to say that I wasn't there for when the robot was programmed so I don't know what kind of speed control algorithm was used. However we did have a CIM that was operating less than optimal. It was geared up and I would guess the speed was closer to around 6-7k rpm. With the final shooter wheel running at about 8-9k rpm (perhaps even faster). I honestly don't remember the gear ratios but this was the estimated speed when we built it.

If you're still looking at using a CIM, AndyMark is working on a product called the spin box that should be available in the next few weeks that is designed for gearing up CIMs. Andy and I discussed it over lunch

Do you happen to know if this SpinBox has a shaft for an encoder?
