#garfield Calendar

04:59 AM Tom_L: brrr
07:04 AM rue_bed: yea
07:16 AM rue_bed: why is the house so cold...
07:17 AM rue_bed: 1.5c outside
07:36 AM rue_mohr: huh
07:37 AM rue_mohr: the scaling of the machines is out, these shoudl fit :)
07:41 AM rue_mohr: wow
07:41 AM rue_mohr: the big piece (the bottom) is out
07:42 AM rue_mohr: 96.5 instead of 95
07:42 AM rue_mohr: I wonder if thats backlash or scale
07:43 AM rue_mohr: no it has to be scale
07:43 AM rue_mohr: oooh
07:43 AM rue_mohr: the belt could be stretching
08:49 AM Tom_L: looks like a snow day
08:52 AM rue_mohr: not here :(
08:52 AM Tom_L: you use it that much?
08:52 AM rue_mohr: they said it would snow tho
08:52 AM rue_mohr: I think its the tension
08:52 AM rue_mohr: lets see
08:53 AM rue_mohr: should be 95mm wide
08:53 AM rue_mohr: its 97
08:54 AM rue_mohr: 2.1%
08:54 AM Tom_L: oh
08:54 AM Tom_L: what about the tooth spacing?
08:54 AM Tom_L: check 10 not 1
08:54 AM rue_mohr: oh, not sure, soemthing metric
08:54 AM Tom_L: better test
08:54 AM rue_mohr: I'll just recal it
08:54 AM Tom_L: box turn out?
08:55 AM rue_mohr: the scale is arbitrary anyhow
08:55 AM rue_mohr: kinda big
08:55 AM rue_mohr: otherwise good
08:55 AM Tom_L: big is better than small?
08:55 AM rue_mohr: the scale on the other machine that did the fitting peice is fine
08:55 AM rue_mohr: but I need the box to be smaller for it to fit
08:55 AM Tom_L: oh so you did print the lid
08:56 AM Tom_L: maybe you should print ajoining pieces on the same printer
08:56 AM Tom_L: if you print the lid on the stretched one now it should fit but not if you calibrate it :)
08:57 AM Tom_L: less plastic wasted
08:59 AM rue_mohr: well I ahve 5 macines
08:59 AM rue_mohr: its silly to wait for 2 consecutive peices
08:59 AM rue_mohr: always with the ei backwards
09:00 AM rue_mohr: it was a thought, but the next thought was that it shouldn't matter
09:00 AM Tom_L: i have 0 machines
09:01 AM Tom_L: you're kinda hoggin em all :)
09:01 AM rue_mohr: I wonder if the belt stretch is linear over time
09:01 AM rue_mohr: I'd think its exponential
09:01 AM rue_mohr: :)
09:02 AM Tom_L: i never had to tighten the spindle belt on the mill
09:02 AM Tom_L: maybe it's shorter and not noticeable
09:02 AM rue_mohr: I might have these beyond spec tension
09:02 AM rue_mohr: without a spec, its hard to tell
09:02 AM rue_mohr: ...longer
09:03 AM rue_mohr: I'm not sure how many years old that machine is...
09:03 AM Tom_L: if you pluck it and it sounds like a G string, it's too tight
09:03 AM rue_mohr: must be ateast 2
09:04 AM * rue_mohr tunes the guitar for a reference...
09:04 AM Tom_L: gonna run a quick errand. back in a few
09:04 AM rue_mohr: I think its more of an A
09:04 AM rue_mohr: I'll be gone
09:04 AM Tom_L: leavin early?
09:04 AM rue_mohr: 7:20
09:04 AM rue_mohr: so, 30 mins
09:04 AM Tom_L: guess it is nearly 7 there
09:09 AM rue_mohr: Tom_L, ... want to do a 3d printer?
09:09 AM rue_mohr: not for a printer as much as a build-project
09:15 AM Tom_L: bak
09:15 AM rue_mohr: yay I finished breafast before I had to run out the door
09:15 AM Tom_L: no budget
09:15 AM rue_mohr: I hae 10 minutes to lolygag
09:16 AM Tom_L: no place to put one either
09:16 AM rue_mohr: oh, less the kitty litter box
09:16 AM rue_mohr: oh their small
09:16 AM rue_mohr: 18" cube or so
09:16 AM Tom_L: i've seen plenty of em
09:16 AM Tom_L: votech has dozens
09:16 AM rue_mohr: as a build project, not to have a printer
09:16 AM rue_mohr: there are all sorts of things I'm sure you would customize
09:17 AM rue_mohr: I had to force myself hard to build the first one as spec'd
09:17 AM rue_mohr: the second one I corrected TONNES of things
09:20 AM Tom_L: yeah seems they're good at reproducing
09:23 AM rue_mohr: ok, kittylitter done
09:23 AM rue_mohr: now I can relax for 3 minutes
09:23 AM Tom_L: then you won't wanna get up
09:23 AM rue_mohr: too late
09:24 AM rue_mohr: so, I can make custom control panels as an SVG and have the esp8266 transact the buttons to serial for me
09:24 AM Tom_L: that was a cool project
09:25 AM Tom_L: not sure i'd trust it to run equipment
09:29 AM rue_mohr: I'd like to work out feedback to the SVG
09:29 AM rue_mohr: you can do ajax in there, so I could enable/disble layers
09:29 AM rue_mohr: no, not for anything critical
09:29 AM Tom_L: like a rice cooker?
09:29 AM Tom_L: coffee maker
09:29 AM rue_mohr: heh yea
09:29 AM rue_mohr: tea machine
09:29 AM Tom_L: that
09:29 AM rue_mohr: set the time on a clock
09:29 AM rue_mohr: replacement for an IR remote
09:29 AM rue_mohr: but kinda different
09:29 AM Tom_L: for the big track?
09:29 AM rue_mohr: thats the current goal
09:32 AM Tom_L: now to figure out what to do all day
09:32 AM rue_mohr: the computer thing you didn't want to do while it was nice out
09:32 AM Tom_L: dunno what that was
09:33 AM Tom_L: supposed to snow all day
09:33 AM Tom_L: not doing much right now
09:37 AM rue_mohr: one of the cnc's is supposed to be part of the "stormy day" list
09:38 AM rue_mohr: bbl
09:39 AM Tom_L: later
07:27 PM rue_mohr: I'm back
07:27 PM rue_mohr: starting to try to snow over here
07:29 PM Tom_L: still here
07:30 PM Tom_L: i think we got 10-12" today
07:30 PM Tom_L: debaiting going out tomorrow
07:33 PM rue_mohr: I wonder when I got that stereo out of the scrap metal pile
07:43 PM rue_mohr: 2017
07:43 PM rue_mohr: march
07:58 PM Tom_L: so mosfets, not real transistors?
08:15 PM rue_mohr: OMG
08:16 PM rue_mohr: you CAN solder to aluminum if you keep it coated in oil, clean it and yea
08:16 PM rue_mohr: wtf
08:17 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220835.jpg
08:17 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220836.jpg
08:17 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220837.jpg
08:17 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220838.jpg
08:17 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220840.jpg
08:22 PM rue_mohr: the reprint pulled up the tape
08:28 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220841.jpg
08:28 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220842.jpg
08:28 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1220843.jpg
08:28 PM rue_mohr: on other fronts the case reprinted close enough!
08:45 PM rue_bed: ok, that looks ok
08:45 PM rue_bed: might need to move it down a bit
08:50 PM Tom_L: yeah that looks decent
09:18 PM rue_mohr: yuppers, solder to aluminum
09:18 PM rue_mohr: 60/40
09:18 PM rue_mohr: and deox
09:29 PM rue_mohr: is this only news to me?
09:34 PM Tom_L: it stuck but i question the bond
09:39 PM rue_mohr: its completely alloyed into the aluminum
09:40 PM rue_mohr: thats why there is a hole in it
09:40 PM rue_mohr: it alloyed right thru
09:40 PM rue_mohr: I did it with a thicker peice and it started to sink right in
09:41 PM rue_mohr: that happens with the special aluminum solder I got too
09:41 PM rue_mohr: if you have some deox or mineral oil give it a try!
09:41 PM rue_mohr: its just 60/40
09:42 PM rue_mohr: pour on oil, scrub the surface, and solder to it
09:42 PM rue_mohr: keep it coated in oil
09:42 PM Tom_L: did it alloy in or did the aluminum foil vaporize?
09:42 PM Tom_L: oxidize
09:42 PM rue_mohr: the thicker peice shows its alloying in
