Useful calculators/spreadsheets?
 

Hello,

I've seen frequent references to JVN's design calculator (http://www.chiefdelphi.com/media/papers/2755) in people figuring out what gearing to use on their designs. I've also seen references to "other" calculators, but I didn't immediately see links and thus was unable to find them when I went back at a later time.

So, my question then ... what useful calculators/spreadsheets do you have links to? Perhaps we can post them here and create a nice resource. I'll update this main post as more links are posted, if any.

Ether's motor calculator/application is really useful! I lean on it when figuring out necessary reductions, etc... I love the feature to put in a parameter (i.e. rpm) and get the torque and current that point.

Paul Copioli's spreadsheet: http://www.fightingpi.org/Resources/...culations.xlsm

Does chain C-C distances, air capacity calculations for those using offboard compressors, and some more detailed drivetrain modeling compared to JVN's spreadsheet.

Accompanying presentation (and a few other useful ones as well) are on Team 1718's website: http://www.fightingpi.org/Resources/...Seminars.shtml

Isn't a calculator, but it counts as a spreadsheet:

Gives most all specs of different motors and most all gearboxes relevant to FIRST. Includes a couple equations but you have to do the math yourself. :D
