12:01 AM rue_shop1: mute jukebox...
12:14 AM rue_mohr: The folks in #electronics on dalnet have been awesome
12:28 AM rue_mohr: CANT SUPPORT WRITE AND READ ENCRYPTION HID CARD
12:28 AM rue_mohr: maybe the HID cards are encrypted
12:29 AM rue_mohr: might expalin why its 125kHz and yet isn't
12:36 AM rue_mohr: so I have a mix of 13Mhz and 125khz cards
12:36 AM rue_mohr: and encrypted cards, and non-encrypted cards
12:36 AM rue_mohr: and the encrypted reader wont read non-encrypted cards
12:36 AM rue_mohr: ouch
04:33 AM Tom_L: seems like a challenge to me
10:27 AM rue_mohr: work starts late today
10:28 AM Tom_L: i got nothin today
10:28 AM * Tom_L waits for a parts order :)
10:30 AM rue_mohr: bits?
10:30 AM rue_mohr: or work stuff
10:31 AM Tom_L: no work today
10:31 AM Tom_L: no aluminum parts order from Ca :)
10:41 AM rue_mohr: heh
10:42 AM Tom_L: know of a good video editor?
10:47 AM rue_mohr: no
10:48 AM rue_mohr: i use kdenlive
10:48 AM Tom_L: i just grabbed a random one
10:48 AM rue_mohr: howd that work out?
10:49 AM Tom_L: it's processing
10:49 AM Tom_L: i'm not about to get into video editing again
10:50 AM rue_mohr: heavy time eater
10:50 AM Tom_L: if it works i'll post it. i just joined those videos to one
10:50 AM Tom_L: i know
10:50 AM Tom_L: it's done though
10:54 AM rue_mohr: a bit of splicing or more complex?
10:55 AM Tom_L: https://www.youtube.com/watch?v=zuVlVK4ChKA
10:55 AM Tom_L: wait for it
10:55 AM Tom_L: not quite done
10:55 AM Tom_L: ok
10:55 AM rue_mohr: heh
10:56 AM Tom_L: that was about a 2 min edit :)
10:56 AM rue_mohr: you got a lot of his on the other one eh?
10:56 AM Tom_L: huh?
10:56 AM Tom_L: i dunno
10:56 AM Tom_L: i just joined the profile, radius and drills all into 1
10:56 AM rue_mohr: a few bit changes eh?
10:57 AM rue_mohr: cool
10:57 AM Tom_L: yeah that's what slows it down
10:57 AM Tom_L: did it view ok?
10:57 AM Tom_L: i'll remove the others..
10:57 AM rue_mohr: yea
10:58 AM rue_mohr: I go in 5 mins
10:58 AM Tom_L: k
10:58 AM Tom_L: got an errand to run then nothing
10:58 AM rue_mohr: did the 1/4" drill do only half way?
10:59 AM Tom_L: no it went all the way
10:59 AM Tom_L: i may speed the RPM up on it a bit
10:59 AM rue_mohr: k
10:59 AM rue_mohr: looks like the pullback could be shorter too
10:59 AM Tom_L: the spindle handles it but the PID needs to be more responsive
11:00 AM Tom_L: retract?
11:00 AM Tom_L: yeah i think that's just how that cycle works
11:00 AM rue_mohr: yup
11:00 AM Tom_L: i could probably lower it a bit
11:01 AM Tom_L: so i left the softjaws one and that new one
11:02 AM rue_mohr: I dropped a demo sprayer off at the paint store and they said "I guess it would be kinda awkward for us to over 50 eh?"
11:02 AM rue_mohr: :S
11:02 AM rue_mohr: they love them, see if we get any orders :)
11:03 AM rue_mohr: says they would go over big in vancouver for property managers
11:03 AM rue_mohr: I gotta go!
11:03 AM Tom_L: go for it
11:03 AM Tom_L: bye
11:04 AM Tom_L: show your buddie how i cut em :)
02:19 PM aandrew: https://i.imgur.com/219CAef.png LOL
04:48 PM polprog: aandrew: hahaha
04:48 PM polprog: "nice try officer"
05:18 PM Tom_L: rue_mohr, new ZRN cutters: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/ZRN_Alum_3flute1.jpg
05:18 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/ZRN_Alum_3flute2.jpg
05:19 PM Tom_L: https://www.americangunsmithtooling.com/pages/what-is-zrn-coating
05:19 PM Tom_L: 3-5 times longer life
07:13 PM rue_mohr: k
07:13 PM rue_mohr: I always break them, so it doesn't matter what their coated with :)
07:13 PM Tom_L: they wouldn't break if you ran them at the right speeds
07:14 PM Tom_L: and missed objects that weren't intended to be cut
07:16 PM rue_mohr: :)
07:17 PM rue_mohr: I use brass hold-down screws now
07:17 PM Tom_L: hahaha
07:17 PM rue_mohr: there have been a few accidents and the bits survived
07:17 PM Tom_L: good call
07:17 PM rue_mohr: :)
07:17 PM Tom_L: well i plan to use these a while and test the setups careully beforehand
07:18 PM Tom_L: they are much better than the cutters i can get locally
07:18 PM Tom_L: as it turns out, i have cutters for SS as well now
07:18 PM Tom_L: those first ones the coating is intended for SS
07:18 PM rue_mohr: :)
07:18 PM rue_mohr: nice soft stainless
07:18 PM Tom_L: but they did very well on Al
07:18 PM rue_mohr: (unless)
07:19 PM Tom_L: very high temp coating
07:19 PM Tom_L: i'm sure i can use them on steel also
07:19 PM rue_mohr: yea, that coating thing again... :)
07:19 PM Tom_L: it's just that on ALTIN the aluminum builds up on the coating if you're not careful
07:20 PM Tom_L: i've been playing with my post template
07:20 PM rue_mohr: teplate?
07:20 PM rue_mohr: set up bits?
07:20 PM Tom_L: for my gcode output
07:21 PM rue_mohr: macros?
07:21 PM Tom_L: it works great, i'm just trying something
07:21 PM Tom_L: no, the actual cad cam post for gcode
07:21 PM rue_mohr: whats in the template?
07:22 PM Tom_L: wanna see it?
07:22 PM rue_mohr: sure
07:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A3/New/LinuxCNC.TMP
07:24 PM Tom_L: there's 2 files for it
07:24 PM Tom_L: one says what gets output and that one says where and when
07:26 PM rue_mohr: yea the macros
07:26 PM Tom_L: that's an old version
07:42 PM Tom_L: oh, i raised that radius tool up .002" too
07:42 PM Tom_L: i saw a tiny scratch mark on the top
07:43 PM Tom_L: but then, i'm not cleaning up the top or bottom surface and the raw material could vary slightly
08:11 PM Tom_L: why can't i get comments turned on on my YT?
08:13 PM rue_mohr: duno
08:14 PM Tom_L: the older ones are set on but i can't get the new ones to allow comments
08:20 PM rue_mohr: damnit, tommorow when i get back remind me to call the hardware shop about fixing the mower!
08:20 PM rue_mohr: damn thing might still be under wsarranty and I just found out who took over the sears warranties
08:20 PM Tom_L: you got a sears mower?
08:21 PM rue_mohr: lawn tractor
08:25 PM Tom_L: ahh i figured it out
08:25 PM Tom_L: if you say it's made for kids, it doesn't allow comments
08:34 PM rue_mohr: hah
08:35 PM Tom_L: had a guy ask about the spindle on one
08:36 PM Tom_L: i never check the comments
08:36 PM Tom_L: i had some old ones i should have replied to but never looked
08:40 PM rue_mohr: that happened to me too
08:43 PM Tom_L: what's wrong with the mower?
08:43 PM rue_mohr: after 25 hours it blew the head gasket
08:43 PM rue_mohr: briggs and stratton
08:44 PM Tom_L: oops
08:44 PM Tom_L: jt makes assembly line stuff for briggs
08:44 PM Tom_L: or he used to
08:44 PM Tom_L: for the factory
08:45 PM Tom_L: were the bolts not tight?
08:45 PM rue_mohr: Its a thin part of the gasket
08:45 PM Tom_L: oh
08:45 PM rue_mohr: I think its just a bad design
08:46 PM Tom_L: years ago i had to use pure copper on my go'kart engines
08:46 PM rue_mohr: for a head gasket?
08:46 PM Tom_L: yes
08:46 PM rue_mohr: 8-|
08:47 PM Tom_L: you could get them
08:47 PM Tom_L: different thicknesses
08:47 PM rue_mohr: I just want the damn gasket so I can get it running again
08:47 PM rue_mohr: so many hoops
08:47 PM Tom_L: go down to the locak briggs store and get one
08:47 PM Tom_L: :)
08:47 PM rue_mohr: and I dont have the ****ing serial number tatood on my hand, so that keeps being an issue
08:48 PM Tom_L: take a pic of it
08:48 PM rue_mohr: I just have to remember when I get home to IMMEDIATLY call the store that does it
08:48 PM rue_mohr: this is the 3rd day I'v gotten home and forgotten
08:48 PM rue_mohr: and I remembered on the drive home
08:48 PM Tom_L: heh
08:49 PM Tom_L: did you hear the lag when it drilled the 1/4" hole on that part?
08:49 PM Tom_L: i wonder if P or I would help that
08:50 PM rue_mohr: I saw it in the strobe from the lights
08:50 PM Tom_L: that was the camera. it doesn't like those led lights right above the mill
08:50 PM Tom_L: my phone
08:51 PM Tom_L: if i tilt it just wrong it does that
09:07 PM rue_mohr: 693997
09:08 PM Tom_L: SN?
09:17 PM rue_shop2: no, the part number for hte gasket I need
09:18 PM rue_shop2: apparenlty one of the iphone upgrades I didn't authorize added support for 2d barcode urls
09:19 PM Tom_L: hmm
09:19 PM Tom_L: mine does that and those square things
09:19 PM rue_shop2: yea thats what I cant remmeber the name of
09:20 PM rue_shop2: something is going on with me, I cant recall anything thats a name
09:21 PM Tom_L: QR Code
09:21 PM rue_shop2: thqnks
09:52 PM rue_shop1: ok I found a case for my battery tabber
09:52 PM rue_shop1: a 700VA APC UPS
10:09 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1190645.jpg
10:09 PM Tom_L: oh, for your welder
10:11 PM Tom_L: oh nevermind. i can see but not read
10:13 PM rue_mohr: I'm not sure how to build the welding points
10:13 PM rue_mohr: apparently they should be ~1/8" copper
10:14 PM rue_mohr: I suppose two lugs for that wire is a start
10:14 PM rue_mohr: I think all the ones I have are either too big or too small
10:14 PM Tom_L: aren't they like tweezers?
10:14 PM rue_mohr: no, side by side
10:14 PM rue_mohr: thats the trick with battery tabbing
10:15 PM rue_mohr: its a surface based tack weld
10:15 PM rue_mohr: fast one
10:15 PM Tom_L: yeah i've seen it done but never done it
10:15 PM rue_mohr: there are a million DIY ones on the internet
10:15 PM rue_mohr: none by me
10:17 PM Tom_L: soon to be one more?
10:17 PM Tom_L: 2 copper wires separated by kapton
10:18 PM Tom_L: it's pretty high temp isn't it?
10:18 PM Tom_L: or mica
10:18 PM Tom_L: nobody uses mica anymore
10:23 PM rue_mohr: it should be a 400A pulse about 20ms long
10:24 PM Tom_L: ultrasonic wire bonding
10:24 PM Tom_L: https://chargedevs.com/features/a-closer-look-at-wire-bonding/
10:26 PM Tom_L: https://accelonix.co.uk/index.php/microelectronics/fully-automatic-wire-bonder/wire-bonding-in-production-of-battery-packs
10:27 PM Tom_L: they do that with plastics all the time now too
10:28 PM Tom_L: hah googling that comes up with alot of assault and battery too
10:38 PM rue_mohr: ?
10:38 PM rue_mohr: and battery eh?
10:38 PM rue_mohr: hmm
10:39 PM rue_mohr: thats a lot of ultrasonic watts
10:51 PM rue_mohr: https://hackaday.com/2014/09/21/a-professional-spot-welder-made-out-of-a-microwave-transformer/
10:51 PM rue_mohr: like that?
