12:09 AM rue_mohr: its crazy
12:13 AM Tom_L: what you workin on?
12:13 AM rue_mohr: it was (calling it done) a "lie detector"
12:13 AM rue_mohr: hand held, bar graph
12:13 AM rue_mohr: battery operated
12:13 AM rue_mohr: descrete button for operating the bar graph
12:15 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/detector/
12:15 AM rue_mohr: I need to change that back to fit by height
12:16 AM rue_mohr: 12 leds, charlieplexed
12:17 AM rue_mohr: t13 runs them in dot mode via ADC in
12:25 AM Tom_L: found it
12:28 AM Tom_L: once that's done i think i've pretty much got everything installed
12:34 AM rue_mohr: o_O
12:34 AM rue_mohr: I made a program that just solved my problem
12:34 AM rue_mohr: zippo:/files/programming/c/resistor# ./OFFSETDIVIDER
12:34 AM rue_mohr: Vin
12:34 AM rue_mohr: R2
12:34 AM rue_mohr: Vout
12:34 AM rue_mohr: R1
12:34 AM rue_mohr: Voffset
12:34 AM rue_mohr: Top resistor: 1000
12:34 AM rue_mohr: Input low value: -5
12:34 AM rue_mohr: Output low value: 0
12:34 AM rue_mohr: Input high value: 5
12:34 AM rue_mohr: Output high value: 3.3
12:34 AM rue_mohr: Voffset is : 2.462687
12:34 AM rue_mohr: R1 is: 492.537323
12:35 AM rue_mohr: coooool
12:35 AM rue_mohr: like I'd already made it
12:35 AM rue_mohr: what I dont know, is how I implement it
12:36 AM rue_mohr: I think I can use an LM317
12:36 AM rue_mohr: not much room on the pcb tho
12:37 AM Tom_L: yay, it compiles now too
12:38 AM Tom_L: good place to stop for tonight
12:38 AM rue_mohr: hmm I need some kinda xlinux chip to play with
12:38 AM rue_mohr: that doesn't cost a million bux
12:38 AM rue_mohr: I had a few didn't I?
12:38 AM rue_mohr: were they all too old?
12:38 AM Tom_L: i forgot where my dev board is
12:38 AM Tom_L: i dunno
12:40 AM Tom_L: only thing i did i'm not crazy about is installed linuxcnc master instead of 2.8
12:40 AM Tom_L: it should still work
05:54 PM TELunus_: rue, my housemate's dad came over the other day and watched a bunch of consecutive hours of netflix on the chineese TV, so I don't think it's going to be a problem.
06:01 PM rue_mohr: ah cool!
06:01 PM rue_mohr: did it smell abnormally hot?
07:14 PM Tom_L: recomend a screen video recorder?
07:14 PM zhanx: for?
07:14 PM Tom_L: linux
07:15 PM zhanx: ok, video recording or desktop recording
07:15 PM Tom_L: desktop
07:15 PM zhanx: Ctrl+Alt+Shift+R
07:16 PM Tom_L: and what does that do?
07:16 PM Tom_L: nothing on this one
07:17 PM zhanx: wait you are not on gnome
07:17 PM Tom_L: obs studio was a suggestion
07:17 PM zhanx: SSR aka Simple Screen Recorder or obs work
07:18 PM zhanx: but OBS is HUGE fyi
07:18 PM Tom_L: i figured.
07:18 PM Tom_L: says it's got everything you'll ever need
07:18 PM zhanx: sudo apt-get install simplescreenrecorder
07:18 PM zhanx: that is a basic one
07:18 PM Tom_L: can you add captions?
07:19 PM zhanx: Open Broadcast Studio aka OBS right?
07:19 PM Tom_L: yeah i think so
07:19 PM Tom_dev: https://itsfoss.com/best-linux-screen-recorders/
07:20 PM zhanx: you can add subtitles later but SSR is lightweight depending on the machine
07:20 PM zhanx: OBS is more for making a youtube cast or something like that
07:25 PM Tom_L: can you limit the screen capture area on either one?
07:25 PM zhanx: yep
07:25 PM zhanx: both
07:26 PM zhanx: OBS tho, is a lot more stuff so a bit harder to do it
07:26 PM zhanx: I would recommend SSR as the recorder
07:26 PM zhanx: then add subtitles after that
07:26 PM Tom_L: k
07:32 PM zhanx: Tom_L, what are you recording anyways?
07:45 PM Tom_L: nothing yet
07:45 PM Tom_L: maybe a howto for some software
07:45 PM zhanx: k
07:56 PM rue_mohr: hmm
09:34 PM rue_shop1: rue_mohr, autopickup w/relay
10:07 PM rue_mohr: build new asterisk box
10:07 PM zhanx: phone issues?
10:08 PM rue_mohr: its reaaaaaly outdated
10:08 PM rue_mohr: there are a few bugs id like to have new ones
10:09 PM rue_mohr: toss the dice again
10:09 PM zhanx: opened the door, have 5 cats in here
10:09 PM rue_mohr: hahah
10:09 PM zhanx: like wow waiting?
10:09 PM zhanx: its warm and i have tuna fish
10:10 PM rue_mohr: so
10:10 PM rue_mohr: it looks like, on average
10:11 PM rue_mohr: a 5V relay in series with a phone line will detect off-hook
10:11 PM zhanx: oh
10:11 PM zhanx: i got space, just need to clear it, i was given permission to use the barn
10:11 PM rue_mohr: how amny other people there?
10:12 PM zhanx: so clearing and frame build tomorrow
10:12 PM zhanx: 6 right now
10:12 PM rue_mohr: any of them temptable to build tech stuff?
10:12 PM zhanx: nope, sadly
10:12 PM rue_mohr: hmm
10:12 PM rue_mohr: it might be an idea not to be too close to home anyhow
10:13 PM zhanx: but at least i can do the frame build now
10:18 PM rue_mohr: I need to figure out exponential progress
10:21 PM rue_mohr: hmm
10:21 PM rue_mohr: my voltage ref will need to pull up and down
