#garfield Calendar

12:11 AM rue_shop2: I wonder if I should set up a square broach head for the arbour press
12:18 AM rue_shop2: something I can peel thru 1/4" aluminum if I like
01:49 AM rue_bed2: so I think I have a layout plan
01:49 AM rue_bed2: tho, it looks like the colours could end up reversing for me
01:49 AM rue_bed2: lots of silver
01:49 AM rue_bed2: have to ponder more
01:51 AM rue_bed2: there is nobody awake in the world right now
01:51 AM rue_bed2: how is that
01:51 AM rue_bed2: maybe you should get out more
01:51 AM rue_bed2: things to do
01:51 AM rue_bed2: yea
01:51 AM rue_bed2: we need to split up somehow
01:52 AM rue_bed2: macros
01:52 AM rue_bed2: macro expansion
01:52 AM rue_bed2: please start with supper
01:52 AM rue_bed2: yes, that would be a nice macro call
01:52 AM rue_bed2: rice dispencer
01:52 AM rue_bed2: you didn't finish it
01:52 AM rue_bed2: we did the frame
01:52 AM rue_bed2: your going to get distracted again aren't ya
01:52 AM rue_bed2: is it a distraction
01:53 AM rue_bed2: sure
01:53 AM rue_bed2: but distraction implies a direction
01:53 AM rue_bed2: z is awake
01:53 AM rue_bed2: hu?
01:53 AM rue_bed2: he is
01:53 AM rue_bed2: how do you know
01:53 AM rue_bed2: I'm not sure, he is doing something
01:53 AM rue_bed2: how do you know?
01:54 AM rue_bed2: he is under a light, its bright, wide
01:54 AM rue_bed2: just standing there, going back and forth doing something
01:54 AM rue_bed2: a plad shirt, but not red
01:54 AM rue_bed2: your crazy
01:55 AM rue_bed2: thanks,
01:55 AM rue_bed2: well, I cant tell what he's doing, so whatever, nice if he turned to the computer
01:55 AM rue_bed2: how far is he from it?
01:55 AM rue_bed2: I dont see one, so 2m or more...
01:57 AM rue_bed2: ok, so
01:57 AM rue_bed2: yes?
01:57 AM rue_bed2: define the brain of a small ai bot would ya?
01:58 AM rue_bed2: using chaotic network groups?
01:58 AM rue_bed2: yea, 2d or 3d ones
01:59 AM rue_bed2: wait, ai models are currently missing a dimension
01:59 AM rue_bed2: yea, and their the wrong dimension
01:59 AM rue_bed2: I think your falling asleep
02:00 AM rue_bed2: I dont think, I know
02:00 AM rue_bed2: I dont think you know either
02:00 AM rue_bed2: whats up tommorow
02:00 AM rue_bed2: oh, dont care
02:00 AM rue_bed2: and after work?
02:00 AM rue_bed2: pillars?
02:01 AM rue_bed2: ah we need to cut lots more rocks
02:01 AM rue_bed2: ok, I could do a few
02:01 AM rue_bed2: power supply
02:01 AM rue_bed2: hmm, how we gonna mask it?
02:01 AM rue_bed2: I say components
02:01 AM rue_bed2: as long as you register them ok I suppose
02:02 AM rue_bed2: sure would be nice to laser cut the masks
02:02 AM rue_bed2: can vynal be laser cut?
02:02 AM rue_bed2: not sure
02:02 AM rue_bed2: do you want to make a knife plotter?
02:03 AM rue_bed2: no, cause, software
02:03 AM rue_bed2: once you solve the math your done
02:03 AM rue_bed2: yea, but its ouch math
02:03 AM rue_bed2: solve once, play forever
02:03 AM rue_bed2: dxf to hpgl?
02:03 AM rue_bed2: hmm
02:04 AM rue_bed2: projects, right?
02:04 AM rue_bed2: damn
02:04 AM rue_bed2: I cant get anything done latley
02:04 AM rue_bed2: the pillars are a great analogy
02:04 AM rue_bed2: billion peices to fit just 200 togethor
02:05 AM rue_bed2: I think your going intermittent
02:36 AM polprog: morning
02:36 AM polprog: so you gonna make it more silver?
09:34 AM rue_mohr: it seems so
09:35 AM rue_mohr: that or introduce a 3rd colour
05:26 PM aandrew: rue_mohr: it would never have occured to me to try to recreate those rear-decorated plastic panels from old equipment
05:26 PM aandrew: that's quite a thread, good job :-)
05:27 PM aandrew: the look of my projects is *always* the last thing on my mind
05:28 PM polprog: i just realized instead of drilling holes for pots and whatnot, i could make my audio pedal project be a PCB that is a cover for the chassis
05:28 PM polprog: electronics on the bottom side (inside), IO on the top (outside)
05:38 PM aandrew: polprog: https://imgur.com/a/g08COIk any interest?
05:38 PM aandrew: I also have a couple USR ISA modems (probably 56k but may be 33k6)
05:42 PM aandrew: heh I forgot about this box of tiny steppers. finding gearing is going to be a challenge: https://imgur.com/a/Y8yTRcI
06:24 PM rue_mohr: huh, imugr wont
06:25 PM Tom_L: werks here
06:26 PM rue_mohr: nice collection
06:26 PM rue_mohr: of motors
06:26 PM rue_mohr: I have the gears you will need
06:26 PM Tom_L: tiny
06:26 PM rue_mohr: but I have no idea how to tell which of the 72829 gears they are
06:34 PM Tom_L: so i got some nice heavy duty resistors today i can sit an look at for another month
06:34 PM Tom_L: rue_mohr, you should have a gear sorting party
06:36 PM rue_mohr: polprog, who did the snappy teardown?
06:36 PM rue_mohr: they are sorted ;)
06:37 PM rue_mohr: box: "gears"
06:37 PM Tom_L: hah
06:37 PM Tom_L: rue_mohr, idea:
06:38 PM Tom_L: you need a shipping container to store all the stuff for your projects so you have room to work on all your projects
06:38 PM Tom_L: they been using quite a few of those around here to build buildings etc
06:39 PM rue_mohr: pff, I know
06:41 PM Tom_L: so if my calcs are correct i'm over halfway thru the wait
06:41 PM Tom_L: almost 3 weeks so far and he said 5
06:52 PM Tom_L: i'm betting 6 or more
06:55 PM aandrew: hm, my kids' U807/807B quadcopter looks like it is compatible (blades/gears/etc.) with the S167 drone
06:55 PM aandrew: this is good, because you can't find U807 anything anymore and I wanted some spare parts
06:55 PM aandrew: funnily enough I'll probably end up spending $100 for spare parts for a $100 drone
06:56 PM aandrew: or what was a $100 drone anyway
06:58 PM aandrew: rue_mohr: hahaha box: gears
06:58 PM aandrew: sounds like my sorting
06:58 PM aandrew: I should get a set of feeler gauges but for pins
06:58 PM aandrew: like 0.5mm to 3mm in 0.5mm steps
06:59 PM aandrew: I bet you could turn something like that (like a step drill in shape) pretty easily
06:59 PM Tom_L: dowel pins
07:00 PM aandrew: amazon's got a set from m1.5 to m6, 350pcs for $36 which is too expensive imo
07:04 PM Tom_L: haha price a set of lab gauges
07:07 PM Tom_L: https://www.amazon.com/Mitutoyo-Steel-Rectangular-Block-Grade/dp/B002SG7QRY/ref=sr_1_26?_encoding=UTF8&c=ts&dchild=1&keywords=Gage+Blocks&qid=1600128317&s=industrial&sr=1-26&ts_id=401584011
07:07 PM Tom_L: not round but same idea
07:10 PM Tom_L: https://www.starrett.com/metrology/product-detail/RC%2088.%20AA
07:10 PM Tom_L: one for 11K
07:11 PM Tom_L: those are inspection room only blocks
07:11 PM Tom_L: kept at temperature
07:11 PM aandrew: I read about those things
07:11 PM aandrew: insane precision
07:12 PM aandrew: perceptron has a few sets of things like that
07:12 PM aandrew: temp chambers, constant humidity etc etc
07:12 PM aandrew: NDI the same
07:15 PM aandrew: I've worked at a few metrology companies come to think of it
07:16 PM aandrew: one was the OEM for Zeiss and a couple others' FIB and SEMs
07:16 PM aandrew: then NDI and Perceptron both are non-contact optical measurement and tracking
07:16 PM aandrew: Synaptive used NDI's stuff to drive their surgical robots to map brain fibers
07:21 PM aandrew: Tom_L: is there an easy way to determine a gear's modulus? or is it just a matter of doing the gruntwork of measuring the outer diameter and counting teeth?
07:24 PM Tom_L: http://fab.cba.mit.edu/classes/863.09/people/cranor/How_to_Make_%28Almost%29_Anything/David_Cranor/Entries/2009/10/12_Entry_1_files/module.pdf
07:24 PM Tom_L: grunt n bear it
07:25 PM aandrew: boo, ok
07:26 PM Tom_L: Outside Diameter = Module × (Teeth + 2)
07:26 PM Tom_L: https://www.quora.com/How-do-I-calculate-the-required-module-of-spur-gears
07:27 PM Tom_L: you might be able to use the invers of that
07:29 PM aandrew: yeah - looks like simplest is modle = OD / (teeth + 2)
07:29 PM aandrew: then I dno't have to try to guess the middle of the tooth when measuring
07:30 PM Tom_L: it'll get you close
09:15 PM Tom_L: rue_mohr, what size wire you recomend for that 100w resistor?
09:15 PM Tom_L: 100 ohm
09:43 PM aandrew: polprog: so no interest in those ISA cards?
09:44 PM aandrew: I don't think anyone else here would be interested, but I thought I'd offer before I recycled them
09:44 PM Tom_L: no isa bus left here that i'm aware of
09:44 PM aandrew: I have a couple on 68k dev boards, but those are also going
09:45 PM Tom_L: i've got 2-3 68332 boards
09:45 PM Tom_L: and a full set of books on it
09:46 PM Tom_L: and the 68hc11 'pink' books
09:46 PM aandrew: I had some, I think I got rid of 'em one or two moves ago
09:52 PM Tom_L: used to have a set of logic books too and got rid of those regretfully
10:01 PM rue_shop2: aandrew, hey, what if I sent you a few different pitches, and you tell me which one fits, then I tell ya what counts I have
11:01 PM zhanx_workshop: ok printing spray nozzles for the hanging beds
11:02 PM zhanx_workshop: gonna drip in the first bottle. and have diffusing sprayers from the next layers
11:10 PM rue_mohr: ?
11:10 PM rue_mohr: interesting
11:11 PM rue_mohr: random question, what colour shirt did you have on last night?
11:12 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1305713305823059968
11:12 PM rue_mohr: I was testing out an idea for machine line work on the power supply face
11:12 PM rue_mohr: if I do the paint properly, I think it'll be great
11:14 PM rue_mohr: backlighting it would be an option, but the case gets in the way of a bunch of the linework
11:14 PM zhanx_workshop: red
11:14 PM rue_mohr: huh, thought it was blue.
11:15 PM zhanx_workshop: its blue now
11:15 PM rue_mohr: ?
11:15 PM rue_mohr: is it a plad like pattern?
11:16 PM zhanx_workshop: my shirts are either solid colors or hawiian
11:16 PM rue_mohr: huh
11:16 PM zhanx_workshop: i own 9 pairs of the same shorts also :D
11:17 PM rue_mohr: so, I'm getting thru the faceplate design for this power supply
11:17 PM rue_mohr: hopefully the guts for it work out
11:19 PM rue_mohr: I'd like larger dials, but, no room
11:21 PM rue_mohr: unless you take a few steps closer to digital and make a select
11:21 PM rue_mohr: I want it all immediate
11:21 PM rue_mohr: stacked dial?
11:21 PM rue_mohr: cmon, you saw the price on those
11:21 PM rue_mohr: hmm and they didn't both push
11:21 PM rue_mohr: finer encoder?
11:22 PM rue_mohr: 3d print a stacked mechanism?
11:22 PM rue_mohr: both?
11:22 PM rue_mohr: I dont want 10 turns on a rear dial
11:22 PM rue_mohr: ok, hmm
11:22 PM rue_mohr: so you want more of a thumbwheel thing, but
11:23 PM rue_mohr: yea, its the but
11:23 PM rue_mohr: if you were gonna do a select
11:24 PM rue_mohr: it would have to be another toggle, and there is no room
