07:40 PM rue_mohr: the mortguage question on twitter is pulling a lot of comments!
07:46 PM polprog: heh, totally random folk
07:46 PM polprog: id say 5 years but thats not real
07:46 PM polprog: eben though
07:46 PM polprog: even*
07:46 PM polprog: if you have a low paidjob and save barely $200 a year, you wont live long enough to save for a house
07:47 PM polprog: if you score well you might make enough in 3 months to buy a nice house
07:47 PM polprog: option 2 is definitely better.
07:53 PM rue_shop1: but then they wont let you have a mortguage even if you have the income
07:55 PM polprog: I mean, you have enough cash to not have a motguage
07:55 PM polprog: if you do it right
07:56 PM polprog: some sorta startup with a nice technology
07:56 PM polprog: but.. that probably wont happen
07:57 PM polprog: ill probably work 9 to 5 as a teacher or academic and sit in an old flat
07:57 PM polprog: im boring
08:26 PM rue_shop1: posting those schematics rustled up a LOT of activity
08:26 PM rue_shop1: there are a few dead hours on twitter
08:26 PM rue_shop1: I might take them over
08:27 PM polprog: yeah, i found that you all are pretty inactive at 12-14 local time
08:28 PM polprog: i should touch up and play wit the class a amp design we did in class
08:28 PM polprog: see how much i can push it
08:29 PM polprog: id set the gain to 1 to see how close to the gain bandwidth product of the bc547 can i get
08:29 PM polprog: im also interested in new oscillators
08:29 PM polprog: but now. bed time
08:30 PM polprog: staying up too late again
08:38 PM rue_mohr: :)
08:45 PM Tom_L: so windows 10 blew it's brains out and the menu doesn't work now
08:47 PM rue_mohr: yea
08:48 PM rue_mohr: that will happen if you dont set up your router to block all the microsoft updates
08:48 PM rue_mohr: every 2 weeks
09:47 PM Tom_L: taking off to fix the bathroom?
09:47 PM rue_mohr: right now I'm just going thru old note pages
09:47 PM rue_mohr: I end up with a lot of them
09:48 PM Tom_L: you just piecing it where needed or the whole room?
09:49 PM rue_mohr: where needed
09:49 PM rue_mohr: maybe even a bit less than I should
11:30 PM rue_mohr: hahaha
11:30 PM rue_mohr: so
11:31 PM rue_mohr: prove me wrong, but it seems that the arduino PID library has a variable called Pon that is never actually used
11:31 PM rue_mohr: it should be a bool, I'm trying to work out why its an int
11:31 PM rue_mohr: ah pOn
11:31 PM rue_mohr: try this again
11:32 PM rue_mohr: OMG
11:32 PM rue_mohr: wtf
11:32 PM rue_mohr: where does code like this come from?
11:36 PM rue_mohr: oh they did it so they could skip ugh
11:39 PM rue_mohr: pOnE = POn == 1;
11:49 PM rue_mohr: so, the tuning params are set to positive or negative values depending on whatever
11:49 PM rue_mohr: and their only accepted in positive values
11:49 PM rue_mohr: but a spare copy is kept in case their read, in which case the copy is sent back to retain the sign
11:49 PM rue_mohr: !?!?!?!
11:51 PM rue_mohr: (Kp>0)?Kp:-Kp;
11:52 PM rue_mohr: just saved 48 bytes of memory
11:56 PM rue_mohr: ah but wait he multiplies them by things
11:56 PM rue_mohr: ugh
