01:32 AM rue_mohr: wow, it takes 8x longer to compile a 64 bit kernel than a 32 bit one
01:37 AM rue_mohr: well I'm guessing 8x based on the progress so far, its not done
03:15 AM swiftshader is now known as fling
11:05 AM rue_bed: yes, being able to turn the tea machine on from bed is good.
11:07 AM Tom_L: :)
11:07 AM Tom_L: now to get it delivered
11:08 AM rue_bed: oooooo
11:09 AM rue_bed: maybe mixed first
11:09 AM rue_bed: something is wrong with my life, I should be excited to be awake, and jumping out of bed to dig back into my project
11:10 AM rue_bed: completely oblivios that I havent showered or eaten
11:11 AM rue_bed: am I just missing infatuation?
11:12 AM rue_mohr: maybe I got too many things and I'm overloaded
11:15 AM Tom_L: why were you compiling kernels?
12:52 PM rue_mohr: cause the debian kernel sucks
12:53 PM rue_mohr: and to build asterisk, I need all the kernel stuff
12:53 PM rue_mohr: so, 2 birds
12:53 PM rue_mohr: I have asterisk installed now, I can spend the next 2 weeks trying to get it working
12:54 PM rue_mohr: they have changed the format and name of every config file
12:57 PM mrdata: why
12:58 PM mrdata: why have they changed the format and name of every config file
01:10 PM rue_mohr: people do, I hate it
01:10 PM rue_mohr: openscad SHOULD have used the povray language
01:10 PM rue_mohr: everything would be happier, and there were modelers
05:22 PM rue_shop1: I wonder how you keep the accumulation of a lifes work from becomming suffocating?
05:22 PM veverak: well, hard to answer as 25 years old
05:22 PM veverak: but recently getting rid of things helped a lot
05:23 PM rue_shop1: that which is valuable can be quite dynamic
05:24 PM rue_shop1: I mean, availability of microcontrollers make a huge difference
05:24 PM rue_shop1: and parts from china
05:24 PM rue_shop1: my shop is quite stocked with boards for parts
05:25 PM rue_shop1: (cheap parts from china are prettymuch a thing of the past now, but it bottomed out the value of the boards for quite a while)
05:25 PM Tom_L: draw a line in the sand and say this is what i've got to play with and continue playing
05:25 PM rue_shop1: there is a balance
05:26 PM Tom_L: but don't take on more
05:26 PM Tom_L: or
05:26 PM rue_shop1: the parts to built things - the space to build things
05:26 PM Tom_L: get rid of some of the old in place of some new
05:26 PM rue_shop1: I was highgrading for a while
05:26 PM Tom_L: mine is in the attic
05:27 PM veverak: working in laboratory helps with this, you can share your staff to others and got stuff from others
05:27 PM veverak: reduce my needs to hoard all stuff
05:27 PM veverak: :)
05:27 PM rue_shop1: indeed
05:27 PM veverak: and being able to say "no, I won't finish this project" helped a lot
05:27 PM rue_shop1: I was trying to sell zhanx on the idea
05:27 PM * veverak gave up on hydroponics this year
05:29 PM rue_shop1: grr, it took almost 200ms for one of the averager channels settle out
05:30 PM Tom_L: that's an eternity
06:13 PM logb0t_ is now known as logb0t
09:15 PM rue_mohr: yup
09:15 PM rue_mohr: but I just found a circuit error
09:16 PM rue_mohr: the reset ties the op-amp to a rail, which is too much for it, it folds over and does evil
09:16 PM rue_mohr: trying to poke in a zener ref in there
09:28 PM mrdata__ is now known as mrdata-
09:46 PM flav0r: HEY !!!!!!
09:47 PM rue_mohr: Hay
09:47 PM flav0r: WHATS NEW ??
09:47 PM flav0r: WHAT HAVE I MISSED ???
09:47 PM * rue_mohr looks left and right
09:47 PM rue_mohr: mmmm well...
09:47 PM rue_mohr: Nothing.
09:47 PM flav0r: SHIT !
09:57 PM Tom_L: why are you shouting?
10:04 PM flav0r: HAPY TO BE BACK !!
10:16 PM mrdata-: uhuh
10:25 PM rue_mohr: almost done modding my board
10:26 PM rue_mohr: really tired tho
10:26 PM flav0r: What board ???
10:26 PM flav0r: Show meeee !!!
10:26 PM rue_mohr: ist a 2 channel peak detector for a filter profiler
10:26 PM rue_mohr: hold on
10:27 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/filterprof/p1120448.jpg
10:28 PM rue_mohr: schematic
10:28 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/filterprof/p1120452.jpg
10:28 PM rue_mohr: I made an error, the reset circuit drives the inputs to the rails, which is beyond the op-amps abilities
10:29 PM rue_mohr: I'm just throwing in a zener regulator to bring it from +-9V to +-6V
10:29 PM rue_mohr: with the op-amps power still being +-9
10:29 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/filterprof/slide.htm
10:30 PM rue_mohr: there have been a lot of dead-ends
10:30 PM rue_mohr: like an analog sine wave gen
10:30 PM rue_mohr: complete disaster
10:33 PM flav0r: Uh oh
11:31 PM rue_mohr: good results with 6V on the rest tho!
11:31 PM rue_mohr: not great, just good
