Re: Gearing for 20 FPS?

Using the oldschool version of JVN's design calc with the drive modeling tab allows you to graph the position and it's derivatives over time, and study what changing mass, friction, power, gear ratio, etc... has on them. It's very interesting how a *slight* friction difference can change speed appreciably.
I just looked at this spreadsheet and I must say, I am floored. As a student who knows very little about DC motor physics (or physics in general), I am amazed at the amount of work that went into creating it. I would be interesting in reading an explanation of some of the math/concepts behind it, if someone would know where to find it. Also, if anyone has any tips on using it now that the motor and gearbox scene is slightly different from where it was in 2004, I would definitely appreciate that too.
Well done JVN, it would be cool to see some of these features re-incorporated into a later iteration of the design calculator.
