06:48 AM rue_mohr: darkrose, so am I gonna help you buy a house in canada?
06:57 AM darkrose: estate agents are all on holiday at the moment, so nothing new added recently, expecting to see some new places show up in the coming weeks
06:57 AM rue_mohr2: hmm
06:57 AM rue_mohr2: brb
07:29 AM darkrose: also, the public transport over there appears to by quite shit
07:31 AM rue_bed: heh, compared to oz, yea
03:03 PM rue_mohr: ok so
03:04 PM rue_mohr: I suppose I need to build a setup for testing software filters
03:06 PM Tom_L: naw
03:06 PM Tom_L: you need to make a widget to sell with parts you want anyway
03:06 PM rue_mohr: heh
03:07 PM rue_mohr: I'll just keep pondering that one
03:09 PM Tom_L: don't ponder too long or somebody else will come up with it
03:29 PM rue_mohr: I dont know that anyone goes near the stuff I'm into
03:30 PM rue_mohr: not one of the 1400+ twitter followers said a peep about that whole project
03:31 PM Tom_L: they don't understand it
03:35 PM rue_mohr: there are a lot of complex people in the group too
04:51 PM rue_mohr: ok, in 3 taps, with an FIR filter, I can do a high pass filter
05:39 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1345698657958432768
05:39 PM rue_mohr: ^^ came out pretty good last night
05:50 PM polprog: I found most people, even sensible ones, just click the <3 and dont comment
05:50 PM polprog: :(
06:45 PM rue_mohr: yea
06:46 PM rue_mohr: it makes me wonder, if a person has like 30k followers, how many comments they actually get
06:55 PM polprog: yeah
06:56 PM polprog: bloody optics
06:56 PM polprog: the prof is making an oral exam
06:56 PM polprog: bastard....
07:03 PM polprog: I wish i could play with the siggen before classes start
07:18 PM rue_mohr: optics eh?
07:18 PM rue_mohr: I found two laser line generators
07:46 PM aandrew: heh if you want public transit in Canada you're gonna be in a city, which means any house with some kind of workshop is going to be mega$
07:46 PM aandrew: rue_mohr: I bought my 8yo a preliminary optics set for christmas. it's got a bright F and a triple laser line and RGB LED and a bunch of lenses/prisms/slits/etc
07:46 PM aandrew: so far he just likes the laser lines
07:46 PM aandrew: but we bounced some stuff around some of the lenses and he liked that
07:48 PM aandrew: rue_mohr: when you start talking about poles and bode plots my eyes cross. I never "got" that, although it's kind of embarassing that I don't
07:51 PM aandrew: polprog: an... oral exam, as in they ask questions and you have to speak?
07:52 PM polprog: yeah
07:52 PM polprog: i should get back to getting the he-ne lazer going
07:59 PM rue_shop1: aandrew, have a link to the set? I'd like to see what they put in
08:03 PM rue_shop1: I suppose I should do a few DC servos for practise
08:03 PM aandrew: rue_shop1: oh it's just a silly one for kids. one moment
08:04 PM rue_shop1: want to know a bit more about the bode plot thing?
08:04 PM aandrew: https://www.amazon.ca/gp/product/B0835TKQRG
08:04 PM aandrew: rue_shop1: I'd love to but tonight my brain is *fried*
08:04 PM aandrew: I don't want to waste your time trying to make this mush understand anything
08:07 PM rue_shop1: cool
08:07 PM rue_shop1: I wonder why an F
08:08 PM aandrew: oh I think I can asnwer that
08:08 PM aandrew: it's a letter which is easy to see flip/invert
08:08 PM rue_shop1: ah
08:09 PM rue_shop1: cool
08:09 PM rue_shop1: I'm gonna make a 2 laser line setup
08:09 PM rue_shop1: once I work out a way I can mount/adjust the modules
08:10 PM rue_shop1: got a bit of a cooked brain
08:10 PM rue_shop1: I need to play with software fitlers
08:10 PM rue_shop1: thankfully, on a PC I can just simulate everyting
08:11 PM rue_shop1: I'm wondering how complex a filter an avr can pull off
08:22 PM aandrew: what are you using the laser line things for
08:24 PM aandrew: rue_shop1: http://mixdown.ca/dump/aop-tech-notes.pdf might be a book you and polprog might be interested in
08:25 PM rue_shop1: the proffessor guy made one up for measuring lenses
08:26 PM rue_shop1: I have a pile of lenses and I'm trying to understand optics
08:26 PM rue_shop1: I ordered some line lasers from ali, then realized I had two big ones in the shop, they weren't quite suitable
08:26 PM rue_shop1: then I found two small ones I'd bought before from ali
08:26 PM rue_shop1: but one was burned out
08:27 PM rue_shop1: so I managed to replace the laser bit from some point lasers and now I'm all good
08:37 PM polprog: looks like a useful book to have at hand :)
08:37 PM polprog: goofnight
08:37 PM polprog: goodnight
08:42 PM rue_mohr: gn
08:45 PM aandrew: 'night
08:47 PM rue_mohr: this will be hard
08:47 PM rue_mohr: I been up till at least 4am for days now
08:47 PM rue_mohr: I need to get up at 6am tommorow
08:48 PM Tom_L: good idea would be to sleep then
08:49 PM rue_mohr: not *yet*
08:49 PM rue_mohr: I have to get to sleep at just the right time
08:51 PM Tom_L: i used to think that too until i broke the cycle
08:53 PM aandrew: I took 10mg melatonin last night, that konked me out pretty quick
08:54 PM aandrew: first time doing that
08:54 PM aandrew: and I am usually asleep within 10m of putting my phone down, gotta stop reading in bed
09:08 PM rue_mohr: I sleep, but don't get rest when I have that stuff
09:08 PM rue_mohr: unless my mind gets onto something, then, not even melatonin can keep me down
09:25 PM polprog: [03:36] rue_mohr: I been up till at least 4am for days now
09:25 PM polprog: [03:36] rue_mohr: I need to get up at 6am tommorow
09:25 PM polprog: same and same >_>
09:56 PM aandrew: well yes if my mind's racing then I'm the same
