12:16 AM rue_shop1: SWEEEEET its working!
01:40 AM rue_mohr: I didn't notice, but oshpark prices went way up
02:00 AM rue_mohr: todo: taxes, shed package, strip down printers, cuttings, aluminum ladle,
04:16 AM Tom_L: morning
09:59 AM rue_mohr: morning
10:04 AM Tom_L: nice sunny day
10:04 AM rue_mohr: hopefully here too!
10:05 AM Tom_L: todone: haircut
10:05 AM rue_mohr: yea!
10:11 AM Tom_L: so both A9-10 & A12 are good as they are now?
10:11 AM Tom_L: cleaning up some old models here..
10:15 AM rue_mohr: I should finish assembling a whole sprayer from them
10:16 AM rue_mohr: looked ok in all the preprocessing
10:17 AM Tom_L: so A8 & C3 do the same thing but for different sprayers
10:17 AM Tom_L: didn't know i had C3 model
10:17 AM Tom_L: haven't done anything with it yet
10:17 AM rue_mohr: C3 is the C version of 3, which is a mix of 8 and 3
10:18 AM Tom_L: which one are you using for the 3"?
10:18 AM Tom_L: C3?
10:18 AM rue_mohr: ...
10:18 AM Tom_L: there was another...
10:18 AM Tom_L: maybe D3?
10:18 AM rue_mohr: ok hold on
10:18 AM rue_mohr: C3
10:18 AM rue_mohr: C3 and D3 are a mix of 3 and 8
10:19 AM rue_mohr: D3 just has a longer trigger
10:19 AM Tom_L: ok
10:19 AM Tom_L: used on the 3" sprayer?
10:19 AM rue_mohr: yes
10:19 AM Tom_L: both being used?
10:19 AM rue_mohr: nobody seems to be asking for D
10:19 AM rue_mohr: C is what we activly use
10:19 AM Tom_L: not much difference is there?
10:20 AM Tom_L: other than the length of the trigger
10:20 AM rue_mohr: yea, D3 is waaay longer
10:20 AM rue_mohr: like to the bottom of the hangle
10:20 AM Tom_L: for fat fingers?
10:20 AM Tom_L: :)
10:20 AM rue_mohr: they specifically asked for it, once.
10:20 AM Tom_L: yeah i can see how that wouldn't work
10:20 AM rue_mohr: it left us with a lot of questions
10:21 AM Tom_L: i'd file it under 'special order'
10:21 AM rue_mohr: their all custom
10:21 AM Tom_L: heh
10:21 AM rue_mohr: but most of the time, they aren't interested in specifying all the details
10:21 AM rue_mohr: like, what size they want the whole sprayer to be
10:21 AM Tom_L: got a model for D3?
11:37 AM rue_mohr: maybe just an outline
11:37 AM rue_mohr: but unless you realyl want ot play, I'd not bother, I dont think we will see a request for them ever again
11:37 AM rue_mohr: we have a bag of like 8 too
11:39 AM Tom_L: ok
11:39 AM Tom_L: more for completeness than anything
11:39 AM rue_mohr: if you wnt
11:40 AM Tom_L: only reason would be if you asked if i had a backup sometime
11:40 AM rue_mohr: lets see...
11:40 AM rue_mohr: you would think I'd not have the design files spread out all over the fileserver eh?
11:41 AM rue_mohr: under different names...
11:42 AM rue_mohr: supertrigger
11:43 AM rue_mohr: thats it
11:45 AM rue_mohr: http://ruemohr.org/~ircjunk/not_public_dont_open/supertrigger-D3.dxf
11:45 AM rue_mohr: its another mixed layer dxf
11:45 AM rue_mohr: hey
11:46 AM rue_mohr: wait
11:46 AM rue_mohr: your cad program
11:46 AM rue_mohr: can it generate views like a blueprint sketch?
11:47 AM Tom_L: probably
11:47 AM Tom_L: no not my cad cam but catia or solidworks can
11:48 AM rue_mohr: I wanted to get some better art for the blowup diagram
11:49 AM rue_mohr: oh, I wonder if meshlab can do it...
11:49 AM rue_mohr: I'm pondering just tracing photos
11:49 AM Tom_L: either sw or catia would need an assembly done for it first probably
11:50 AM rue_mohr: well, the only thing that didn't look quite right in my drawing was the handle
11:50 AM rue_mohr: (ahahahahahaha)
11:50 AM Tom_L: i can generate drawings from catia or sw and maybe save them as dxf?
11:56 AM Tom_L: was that dxf inch or mm?
11:56 AM rue_mohr: mm
11:56 AM Tom_L: save me some trouble later on :)
11:56 AM rue_mohr: the activation end of it shoudl just about completely match A8
12:00 PM Tom_L: 6.3mm thick?
12:00 PM Tom_L: .250
12:00 PM rue_mohr: .25
12:01 PM Tom_L: haha
12:01 PM rue_mohr: ?
12:01 PM Tom_L: no wonder sw isn't working as expected
12:01 PM rue_mohr: metric imperial?
12:01 PM Tom_L: i opened 2004
12:01 PM Tom_L: instead of 2015
12:01 PM rue_mohr: ? ok
12:02 PM Tom_L: i'm booted in the 32bit win ssd
12:02 PM Tom_L: so i have a sw model now though
12:05 PM * Tom_itx goes to reboot 64bit
12:09 PM Tom_L: what view do you want?
12:09 PM Tom_L: for the new handle
12:10 PM rue_mohr: oh, some angled view like the exploded diagram
12:11 PM rue_mohr: can it do it?
12:11 PM Tom_L: dxf or what?
12:13 PM rue_mohr: dxf, raster image, anyting really
12:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/B2_proto/
12:15 PM Tom_L: see what that dxf looks like
12:15 PM rue_mohr: oooo
12:16 PM rue_mohr: http://www.ruemohr.org/p1190526.jpg
12:16 PM rue_mohr: its almost a flip of that view
12:16 PM Tom_L: i can filip it
12:17 PM Tom_L: gotta reboot...
12:17 PM rue_mohr: no, dont worry then
12:17 PM Tom_L: no, sw crashed
12:17 PM Tom_L: take about 15 sec
12:17 PM rue_mohr: I did those drawings as a rough sketch to see if its the kind of blowup drawing I wanted
12:18 PM rue_mohr: one of the things I realized was that If I was going to do computer model, I'd have to model all the parts
12:18 PM Tom_L: takes longer to find where i was than to do the task
12:18 PM rue_mohr: which is an awefull lot of effort for a blowup diagram
12:18 PM rue_mohr: so I decided that at some point, I'll take pictues and trace them
12:20 PM Tom_L: grab that dxf again
12:21 PM rue_mohr: it looks good doesn't it?
12:21 PM rue_mohr: a few of the verticies could be cleaned out, but yea
12:21 PM rue_mohr: (post editing)
12:21 PM Tom_L: i could maybe hide the radius'd edges
12:22 PM rue_mohr: I dont think the software is likley to make good judgement calls on it
12:22 PM Tom_L: nope
12:22 PM rue_mohr: I like the look of it tho
12:24 PM Tom_L: wish i could save it without all the sheet data with it
12:24 PM rue_mohr: super easy to filter out
12:24 PM Tom_L: not sure how.. i don't do that very often
12:25 PM Tom_L: did that give you something to work with or should i turn off radius'd edges etc?
12:28 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/2dhandle.dxf
12:28 PM rue_mohr: takes me longer to copy the files around than to edit it
12:28 PM rue_mohr: heh
12:28 PM rue_mohr: thats great
12:28 PM rue_mohr: I wonder if I should trace the other parts out in cad to keep it kinda looking the same
12:29 PM Tom_L: the ones i have in sw i can get you the same way
12:29 PM Tom_L: no need to trace
12:29 PM rue_mohr: sure
12:30 PM Tom_L: gimme a sec and a list...
12:30 PM rue_mohr: the head wont work tho, its bent
12:30 PM Tom_L: right
12:30 PM rue_mohr: jester did a sheetworks version
12:30 PM rue_mohr: it calculated the backcut for the tabs
12:30 PM rue_mohr: didn't work out, the part just doesn't have the meat for it
12:34 PM Tom_L: yeah that doesn't look so bad
12:35 PM Tom_L: you need A8?
12:38 PM rue_mohr: sure
12:39 PM rue_mohr: see if you can get about the same angle and I'll stitch
12:39 PM Tom_L: same directory
12:39 PM Tom_L: A8_A
12:39 PM Tom_L: had some A8 dxf already :)
12:40 PM rue_mohr: it doesn't like doing this,
12:40 PM rue_mohr: oh old message
12:40 PM rue_mohr: carefull not to overwrite the profile file :)
12:40 PM rue_mohr: I think the angle is a bit steper on that A8
12:40 PM Tom_L: i'm not keeping this one
12:41 PM Tom_L: one sec
12:42 PM Tom_L: grab that file again
12:42 PM Tom_L: used the 'standard' view angle
12:44 PM Tom_L: what else?
12:49 PM Tom_L: A12_A
12:49 PM Tom_L: same dir
12:50 PM Tom_L: don't have A3 that i can use
12:50 PM Tom_L: yes i do
12:53 PM Tom_L: A3_A
12:55 PM Tom_L: i can do more later if i have models but i think that may be it
12:56 PM rue_mohr: :)
12:57 PM rue_mohr: ma would like a hot glue pot
12:57 PM rue_mohr: just gonna do one up
12:57 PM Tom_L: headin out for a bit
03:17 PM Tom_L: .
03:29 PM rue_mohr: made ma a glue pot
03:29 PM rue_mohr: I have a pictrue I'll post later
03:30 PM rue_mohr: used a halogen lamp like the solder pot
04:34 PM Tom_L: for what?
04:42 PM rue_shop4: ma does crafts
04:43 PM Tom_L: what kindof hot glue?
04:43 PM rue_shop4: hot glue gun glue
04:43 PM Tom_L: oh
04:43 PM Tom_L: i was thinking animal glue
04:45 PM rue_shop4: 8-| this random chips I pulled is a RGB video ADC
04:45 PM rue_shop4: 270MSPS
05:19 PM aandrew: rue_shop4: looks like I'll be in BC for a couple weeks around start of september, if you're open to it I could probably stop by for a visit
05:19 PM aandrew: RGB video *adc* ?
05:19 PM aandrew: interesting
05:20 PM aandrew: also: this is the first time I'm intentionally avoiding an order with digikey due to their performance of late, both of the website and of the shipping in general
05:20 PM rue_shop4: yea
05:21 PM rue_shop4: also found some 36 bit recievers and transmitters
05:21 PM aandrew: anyway, time to queue up a movie to play PiP with the kicad BOM tool on the tablet
05:21 PM aandrew: that damn thing is the best bit of software I've used in years
05:22 PM aandrew: rue_shop4: I've worked quite a bit with those serdes chips. they work really nicely for getting a lot of parallel bits from A to B
05:24 PM rue_shop4: I'd like to combine the ADC, an FPGA and some FIFO ram and make a scope backend
05:38 PM aandrew: *nods* one of the boards I made for perceptron would be a nice scope digitizer; 5 channels going to a Max10 and the Max10 connected directly to gigabit ethernet. It's got some SDRAM (untested) and a fancy STM32F7 connected to the FPGA too
05:38 PM aandrew: -ENOTIME of course
06:10 PM rue_shop4: :)
08:34 PM rue_mohr: so, it turns out the output of the 48V on the switch power supply floats, even from the 12V supply in it
08:41 PM Tom_L: isolated?
09:32 PM rue_shop4: yea
09:37 PM rue_shop4: 3p 10s
09:37 PM rue_shop4: at about 10.5Vea
09:38 PM rue_shop4: so about 105V
09:38 PM rue_shop4: whats odd, is that it doesn't look like they did proper current contro
09:38 PM rue_shop4: l
09:39 PM rue_shop4: 47W
09:39 PM rue_shop4: so they might be 1W leds
09:39 PM rue_shop4: 4 dies in each led
09:40 PM rue_shop4: 150mA I think
09:46 PM Tom_L: huh
10:10 PM rue_mohr: Tom_L,
10:10 PM rue_mohr: do you know if all the triangular carbide inserts are the same size?
10:10 PM rue_mohr: https://www.aliexpress.com/item/1005001479901459.html
10:10 PM rue_mohr: I have no idea how to confirm they match my tool
10:13 PM rue_mohr: hmm, so many types to choose from
10:14 PM rue_mohr: coated is pointless, I always break them
10:22 PM rue_mohr: all the china ones are 16xxx
10:23 PM rue_mohr: the ones I think I got are "1/4"
10:23 PM rue_mohr: 14xxx
10:28 PM rue_mohr: I'm not seeing different sizes
10:50 PM Tom_L: no they are different sizes
10:50 PM Tom_L: one sec
10:51 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/inserts/
10:51 PM Tom_L: the html there is one of the most complete guides
10:53 PM Tom_L: the sherline ones are smaller
10:54 PM Tom_L: depends what the application is
10:54 PM Tom_L: boring bar, lathe tool, mill cutter etc
10:54 PM Tom_L: several sizes for boring bars for example
10:58 PM Tom_L: i had a catalog on there somewhere
10:58 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/SANDVIK_TURN_H.pdf
11:00 PM Tom_L: that might just be tooling
11:04 PM Tom_L: those ali numbes may not follow that chart though
11:08 PM Tom_L: T=triangle, P=11deg, K=corner point, R may be wrong on those charts...
11:09 PM Tom_L: you should find a chart that matches your numbering
11:09 PM Tom_L: likely metric over inch
11:10 PM Tom_L: https://www.iscar.com/eCatalog/item.aspx?cat=5604705&fnum=459&mapp=IT&app=92&GFSTYP=M
11:12 PM Tom_L: https://www.iscar.com/eCatalog/Item.aspx?cat=5600931&fnum=459&mapp=ML&GFSTYP=M&srch=1
11:14 PM Tom_L: i'm guessing but the 1603 could be 16mm point to point x 3mm thick
11:17 PM Tom_L: https://www.ingersoll-imc.com/product/5609144
11:17 PM Tom_L: 16 may also be the inscribed circle diameter
11:19 PM Tom_L: seems kinda big
11:25 PM Tom_L: https://cadem.com/iso-turning-insert-nomenclature/
11:25 PM Tom_L: might help
11:26 PM Tom_L: so i think i was right on the thickness
11:26 PM Tom_L: the 16 may be the cutting edge length instead of the inscribed circle
11:40 PM Tom_L: http://www.mitsubishicarbide.com/en/technical_information/tec_turning_tools/tec_turning_insert/tec_turning_guide/tec_turning_identification
11:40 PM Tom_L: it just depends if they're inch or metric
11:40 PM Tom_L: yours are likely metric
11:49 PM rue_mohr: oh, but are all the Triangle ones the same triangle size?
11:49 PM rue_mohr: hmm
11:50 PM Tom_L: no
11:50 PM Tom_L: i doubt it anyway
11:51 PM rue_mohr: best I can tell, the ones I have are "1/4 inch"
11:51 PM Tom_L: that's the 1603 number
11:51 PM Tom_L: doesn't sound like it
11:51 PM Tom_L: measure them and see what you get
11:51 PM rue_mohr: cant, I broke off all the corners
11:51 PM Tom_L: but i haven't seen yours
11:52 PM Tom_L: should have checked one before that :)
11:52 PM rue_mohr: KMS tools, "magnum"
11:52 PM rue_mohr: which is usually rebranded china
11:53 PM Tom_L: is there any number on the holder?
11:53 PM rue_mohr: nope
11:53 PM rue_mohr: I suppose I'll have to see
11:53 PM rue_mohr: its odd, the holder I have uses a screw to hold down the bit
11:53 PM Tom_L: what makes you think they're 1/4"?
11:54 PM Tom_L: yeah there are different attachment methods
11:54 PM rue_mohr: I cant find any holders from china that use the triangle insert for left/center/right with a screw, there are only left and right and they use a top clamp
11:54 PM Tom_L: typically a center screw on T inserts
11:54 PM Tom_L: then try that chart on my site
11:54 PM Tom_L: it's inch i think
11:55 PM Tom_L: you should be able to draw a triangle on paper with the 3 given sides and measure that
11:55 PM Tom_L: should be enough left of the cutter for that
11:56 PM Tom_L: unless you _really_ screwed up
11:56 PM rue_mohr: wow the kms tools site is slow
11:57 PM rue_mohr: https://www.kmstools.com/magnum-carbide-insert-1-4-quot.html
11:57 PM Tom_L: but see, the 1603 throws me off but that's not the number on your cutters
11:57 PM Tom_L: there you go then
11:57 PM Tom_L: if you think that's right
11:59 PM Tom_L: but there is no "H" in the 2nd place on the inch charts that i see
11:59 PM rue_shop4: huh, the insert I have is more in the order of 1/2"
11:59 PM Tom_L: yeah
11:59 PM rue_shop4: in the order of tho
11:59 PM Tom_L: so those aren't the ones you need
11:59 PM rue_shop4: its not close
11:59 PM Tom_L: those are maybe for a boring bar etc
