07:01 AM rue_mohr: zippo:/morfiles/programming/c/turncalc# ./turnCalc --help
07:01 AM rue_mohr: This program solves constant stuff.
07:01 AM rue_mohr: -h --help is the help your looking at
07:01 AM rue_mohr: -v --voltage set applied voltage (v)
07:01 AM rue_mohr: -n --turns number of turns
07:01 AM rue_mohr: -a --area core area (m^2)
07:01 AM rue_mohr: -t --time applied votlage time (s)
07:01 AM rue_mohr: -b --flux Peak flux (T)
07:01 AM rue_mohr: aha! 'turncalc' is what I'm looking for.
07:02 AM rue_mohr: oh maybe not, I need a generic form that boils unknowns into a constant
07:05 AM rue_mohr: well
07:05 AM rue_mohr: flux and area are what I want to have as the k factor
08:03 PM rue_mohr: ok, 11 hr day at work

08:40 PM rue_shop2: so, we want 24V, what is the minimum numbers of turns to keep the frequency under 40kHz
08:53 PM * rue_shop2 looks at polprog
08:54 PM rue_shop2: didn't you do a thesis, dissertation, or paper on this at some point?
11:40 PM rue_shop2: huh, the lowest magnetization loss occurs when you drive it almost right up to saturation
