12:35 AM rue_mohr: I'm having a hard time with the fixed 20db/decade thing
12:35 AM rue_mohr: I know I need to stick a slight non-linearity thing in there to change it, and I'm not quite sure how
12:35 AM rue_mohr: maybe going back to the votlage divider that it comes from is a good start
01:07 AM rue_mohr: huh, thats intersting
01:08 AM rue_mohr: that voltage divider curve isn't the same as the low pass
11:55 AM rue_mohr: so, to be able to modify the slope, I need to know the freqency of at the current time
11:57 AM rue_mohr: but then I need to use it to pull of a power function
11:57 AM rue_mohr: Vo += Vi*pow(freq, 0.75); // re-sloped integrator
12:19 PM rue_mohr: I'm gonna need something that tells me the rolloff!
05:30 PM rue_mohr: http://paste.debian.net/1181560/

07:47 PM rue_shop1: what else we got
07:47 PM rue_shop1: cy7c1329H
07:49 PM rue_shop1: 4-mbit (128k x 36) Pipelined DCD Sync SRAM
07:50 PM rue_shop1: I think its 4 port ram
07:52 PM rue_shop1: no, I'm not sure actually
07:55 PM rue_shop1: xc95288
07:57 PM rue_shop1: cpld
08:43 PM Tom_L: both maybe?
09:08 PM rue_mohr: this really is good prep for being the last person alive in the universe
09:09 PM rue_mohr: I think I need to set goals and keep a pace
09:11 PM Tom_L: yep
09:12 PM Tom_L: we are thinning out ehh?
09:26 PM rue_mohr: it doesn't seem to matter how many sources I add, its all going quiet
09:27 PM rue_mohr: there are things it would be really good for me to be doing and I just cant seem to get to them
09:29 PM Tom_L: alot of crap going on in the world of recent
09:30 PM Tom_L: i'm not getting much accomplished either
09:30 PM rue_mohr: a group project would be nice
09:31 PM rue_mohr: I'd also like to get the hardware for the z axis of the cnc built
09:33 PM rue_mohr: I suppose I'll put a PID on an atmega8 this week
09:33 PM rue_mohr: play with it
09:34 PM rue_mohr: after that I can try a high/lowpass
