01:15 AM XXCoder: covers is insane.
03:22 AM travis_farmer[m]: Morning ☕️
04:27 AM Tom_L: morning
04:52 AM JT-Cave1: morning
05:55 AM Lcvette[m]: morning
06:03 AM JT-Cave1: zero updates this week arggg
06:04 AM -!- #linuxcnc mode set to +v by ChanServ
06:08 AM JT-Cave: I feel like I'm on GGG 30 minutes to shop, prepare and eat breakfast
06:27 AM Lcvette[m]: GGG?
06:27 AM JT-Cave: Guy's Grocery Games
06:27 AM JT-Cave: C8Tracker and another have not had any updates since Friday
06:27 AM Lcvette[m]: never heard
06:28 AM Lcvette[m]: bugger
06:28 AM JT-Cave: AFAIK the C8 will roll off the assembly line Friday morning...
06:28 AM Lcvette[m]: \o/
06:28 AM Lcvette[m]: maybe no news is good news
06:28 AM * JT-Cave hits the shower as he has to roll out of here shortly
06:29 AM JT-Cave: maybe... I check with Phil this afternoon to see if he has any updates
06:33 AM Lcvette[m]: 👍️
07:06 AM NoGodDamnIdea: hello everyone
08:19 AM Loetmichel: *giggle* ... THAT co-worker again. "Hey, loet, can you help me real quick? That 30" Dell Monitor is so heavy. Can you move it into the measurement chamber?" $me: *lift* "WTF? that thing has 10kg(22lb) at max!" *put it on the shipping scale* "Ok, 16kg(35lb). Still. Work out a little more, man!"
08:29 AM Scopeuk: I mean for a monitor that is heavy
08:29 AM Scopeuk: and probably a little awkward
08:29 AM Scopeuk: but 16kg isn't "that" heavy
08:29 AM Loetmichel: indeed
08:29 AM travis_farmer[m]: i remember the old CRT monitors...
08:30 AM Loetmichel: I repaired them back in the CRT TV days
08:30 AM Scopeuk: nothing on modern monitors will ever be as satisfying as a degause coil
08:30 AM Scopeuk: they are however better in every other way
08:30 AM Loetmichel: *klick* *BOINGGGGGGG*
08:30 AM Scopeuk: bonus points if there is a whole row of them and it makes the rest go wavey
08:30 AM travis_farmer[m]: lol
08:30 AM Loetmichel: yep
08:32 AM Scopeuk: this was half the fun of taking it classes at school in the crt era
08:32 AM Scopeuk: hit degauss and watch the entire labs worth of monitors dance
08:33 AM * Loetmichel had to lift and secure our 46" plasma TV at the old bedroom a while ago. THAT was a bit straining because i couldnt see where i was supposed to meet the wall cradle and wife stood to the side and said "More up, more left, tilt it a bit right..." while i was strugging at max arm length to hold those 50kg of steel and glass steady :)
08:34 AM travis_farmer[m]: off-topic... anybody here use a SDR (software defined radio) for listening to radio bands? mine seems to get hot. not magic smoke hot, or burn your fingers hot, but quite hot...
08:35 AM Loetmichel: travis_farmer853: you mean those USB dongles with the (tv) tuner chips in them?
08:35 AM Loetmichel: those get pretty hot indeed.
08:35 AM travis_farmer[m]: yeah
08:36 AM travis_farmer[m]: ok, so it is normal?
08:39 AM Loetmichel: pretty much, yeah
08:39 AM Loetmichel: those tuner dongles run hot in normal operation
08:40 AM travis_farmer[m]: you would think they would have a larger heatsink, than just the metal package ;-)
08:40 AM Loetmichel: the smaller those USB dongles are the hotter they get
08:41 AM Loetmichel: because the maximum allowed power they get is 2.5W. So if they have less surface to dissipate they get hotter
09:12 AM Unterhaus_ is now known as Unterhausen
09:15 AM Unterhausen: we had a really nice SDR at work. It was pretty wild getting it started in the lab with a packet analyzer, there was a lot more going on in there than you would think
09:53 AM Scopeuk: part of me finds the idea of running an sdr sweep and "seeing" what is bouncing around near me really interesting. I've yet to pull the trigger on an sdr unit however
10:17 AM CloudEvil: Well, they start out at $8ish
10:24 AM Scopeuk: yeh, mostly I'm interested in the low power digital stuff on 433mhz
10:25 AM Scopeuk: should just buy one at some point
11:45 AM Avakato[m] is now known as Avakato3342[m]
12:25 PM -!- #linuxcnc mode set to +v by ChanServ
12:25 PM JT-Shop: Lcvette[m], they just confirmed Monday's numbers and I'm still good for Friday Morning!
12:45 PM Tom_L: 1 day closer..
12:49 PM JT-Cave: yup
01:04 PM JT-Shop: XXCoder, looks like Missouri is going to join 20 other states and adopt LEAD-K
01:21 PM roycroft: oregon hasn't, and i don't know if we will
01:21 PM roycroft: lead-k is rather controversial
01:22 PM roycroft: i don't claim to know enough about the issues to make an informed judgement, but i know that oregon has been slow to address it
01:48 PM * JT-Shop just ordered a replacement set of jaws for the #93A... seems like he gave the better one to the young gear head
02:27 PM roycroft: tina turner has left the building
02:28 PM travis_farmer[m]: just saw that myself...
02:37 PM XXCoder: jt interesting. didnt hear of it till now
02:38 PM JT-Shop: it was in the local paper today
03:12 PM roguish[m]: what's LEAD-K ????
03:14 PM XXCoder: program to assist family of deaf baby so deaf chilod will grow up with better commucation and such
03:14 PM XXCoder: im sure its not whole of program but yeah
03:15 PM roguish[m]: sounds ok. no pun inteneded
03:16 PM roguish[m]: and Tina Turner was a real rocker....
03:18 PM roycroft: and she was literally brutalized by ike, but despite that she survived and made the world her's
04:06 PM CaptHindsight[m]: XXCoder: https://www.deaffocus.org/lead-k "3 out of 4 parents of dead children don't sign" !?
04:06 PM CaptHindsight[m]: sorry deaf not dead
04:07 PM XXCoder: common typo, happens to me too
04:07 PM XXCoder: and yeah many people dont know asl exists so they simply dont do anything for kid
04:07 PM XXCoder: as result they grow up with no language :(
04:08 PM XXCoder: im not of 92% so I cannot imange what its like
04:10 PM CaptHindsight[m]: horrifying
04:11 PM XXCoder: yep. generally more remote areas are the worse off they are :(
04:31 PM CaptHindsight[m]: on the other hand we have millions that squander their access to education
04:35 PM roycroft: xxcoder: i watched that video some time ago
04:35 PM roycroft: it was enjoyable
04:36 PM XXCoder: nice. yeah its pretty awesome
04:36 PM roycroft: i've always had an interest in bookbinding
04:36 PM roycroft: and i've known for as long as i can remember that there's a lot more too binding a book than 99.999+% of the population think
04:38 PM XXCoder: modern method is really simple, but also lower quality
04:38 PM XXCoder: but yeah old bookbinding wow
04:38 PM XXCoder: you ever seen that woman making books?
04:38 PM roycroft: regarding lead-k, it seems that many of the criticisms are that it focuses on signing as one's primary means of communication, and many societies that deal with deaf people disagree with that
04:39 PM XXCoder: she does amazing works like 4 books of magic elements "spellbooks" like water, fire so on
04:39 PM roycroft: but again, i'm not familiar enough with the issues to have an informed opinion
04:39 PM roycroft: i don't think i have seen the person you're talking about's works
04:39 PM XXCoder: forcing deaf to solely focus on speaking results in "broken hearing person"
04:39 PM XXCoder: hold on for link
04:39 PM roycroft: that's another extreme
04:40 PM XXCoder: not relaly as it allows deaf person choice
04:40 PM roycroft: instinctively i would think that a combination of lip reading/speaking and signing would be the best approach
04:40 PM XXCoder: do you realize how hard lipreading is?
04:40 PM XXCoder: I cannot do it.
04:40 PM roycroft: i think i have a sense of it, but no, i won't pretend that i know how hard it really is
04:41 PM roycroft: i'm just saying that forcing a person to only sign is an extreme, and forcing a person to only lip read/speak attempt is an extreme
04:41 PM XXCoder: element of water https://youtu.be/iilzq55hj-Q
04:42 PM roycroft: thanks
04:42 PM roycroft: i'll bookmark that and watch it when i have the time
04:42 PM XXCoder: video editing makes it hard for me to watch her videos so I never did sub to it
04:43 PM XXCoder: if I recall right, lipreading captures about 25% of words.
04:43 PM XXCoder: thats with expert
04:43 PM roycroft: lipreading depends a lot on context, i should imagine
04:43 PM XXCoder: yeah
04:43 PM roycroft: so random lipreading is probably all but impossible
04:44 PM XXCoder: I only know of basic stats of it. its way too hard for me
04:44 PM XXCoder: and its before I even had vision tracking issues
04:44 PM XXCoder: imange trying to lipread when you cant stare at spot consiently
04:44 PM roycroft: i.e. if you drop someone in the middle of a room, and they have no idea where they are, who any of the other people are, or why they're talking to each other lipreading is probably not possible
04:45 PM roycroft: but if you know the people, know the place, and have a sense of what they're discussing it's probably possible to understand a fair amount of what they're saying by lipreading
04:46 PM XXCoder: sure. often people dont bother to explain though. not even if said deaf person is family
04:46 PM roycroft: but then again, we had a president who said aloud "read my lips! no new taxes!"
04:46 PM XXCoder: for a lot of deaf people, family events like xmas is a grind
04:46 PM XXCoder: lol
04:46 PM roycroft: and nobody understood that, especially when he raised taxes
04:47 PM XXCoder: hah thats funny :D
04:47 PM roycroft: at least you don't have to listen to drunk uncle
04:47 PM roycroft: you still have to see him and smell him
04:47 PM XXCoder: cant smell
04:47 PM roycroft: well that's almost better than not hearing, when it comes to drunk uncle
04:47 PM XXCoder: I only have one uncle left, hes mostly ok though. never drunk
04:47 PM XXCoder: one that used to, died from alchol poisoning.
04:48 PM roycroft: almost every family has a drunk uncle, who does not necessarly have to be drunk nor anyone's uncle
04:48 PM XXCoder: do you know how hard to get that, if youre used to drinking? he drank insane amount of volka.
04:48 PM XXCoder: 7 bottles in 2 days
04:48 PM roycroft: yeah, that's a lot
04:48 PM roycroft: most people pass out, throw up, or usually both, before they get to the point of alcohol poisoning
04:48 PM XXCoder: techinically died by heart attack, because he didnt have enough blood
04:49 PM XXCoder: vampires probably would have called him a fine vinage
04:49 PM roycroft: but in the end
04:49 PM roycroft: he was potato
04:49 PM XXCoder: lol
04:50 PM XXCoder: he had same problems as me with back. couldnt work at all. but then I didnt drink achol ever
04:50 PM XXCoder: seriously glad I use cbd to keep it to reasonable pain
04:59 PM mits5782[m]: Anyone here know how to move the origin in freecad?
05:01 PM mits5782[m]: wrong window, ignore
05:02 PM XXCoder: there should be freecad discord also
05:04 PM mits5782[m]: There probably is, I was just trying to ask in a group chat... wrong window though 🙂
05:04 PM XXCoder: :)
05:04 PM XXCoder: it does exist. im at freecad irc which is bridged to matrix and discord
06:02 PM snaked is now known as snakedd
07:05 PM roycroft: so nursery plants are the latest thing to go bonkers in price, for whatever reason (probably shortage of labor)
07:05 PM roycroft: i used to get six-packs of small annual flower starts, like impatiens or marigolds, for $3.99
07:06 PM roycroft: now they're $5.99 for a single plant that's the same size as the six-pack plants
07:06 PM XXCoder: most of labor shortages would be solved with increase of pay
07:06 PM roycroft: and the pricing for herb starts is similar
07:06 PM roycroft: yes, and that increase in pay would not cause the huge price spikes that we're seeing
07:06 PM Tom_L: they are likely paid what they are worth
07:06 PM Tom_L: not many want to work that hard anymore
07:07 PM roycroft: that's another part of the problem
07:07 PM roycroft: i used to start all my garden plants from seed
07:07 PM Tom_L: and of course not what they _think_ they're worth
07:07 PM roycroft: i'd put some heating pads under some flats with bright lights above them and start growing things in january
07:08 PM roycroft: but i've been buying starts in april-may from the nurseries lately, because it's easier and probably cheaper, given the cost of electricity for the lights and heating pads
07:08 PM roycroft: now it's definitely not cheaper
07:08 PM XXCoder: wonder how much power it would need
07:08 PM Tom_L: make a hot box from an old screen door
07:09 PM XXCoder: and if solar panels can supply that
07:09 PM roycroft: sure, solar panels could supply it
07:09 PM roycroft: but i'd be a couple thousand dollars into solar panels, at least, to get started
07:09 PM roycroft: anyway, i have some pretty flowers now
07:09 PM XXCoder: true
07:10 PM roycroft: not as many as i'd like, but enough to make the property look nicer
07:10 PM roycroft: and i got some more basil starts, because it's impossible to have too much basil
07:10 PM roycroft: that's like having too many clamps
07:10 PM roycroft: the concept is unfathomable
07:11 PM roycroft: on the other hand, any number of zucchini plants greater than 1 is too many
07:11 PM roycroft: because 1 zucchini plant will feed an entire neighborhood
07:11 PM perry_j1987: evening
07:12 PM roycroft: it should be called the jesus plant
07:12 PM roycroft: because just like jesus started breaking up a single loaf of bread and fed the masses with it
07:12 PM roycroft: when you start harvesting a single zucchini plant you can feed the masses with it
07:13 PM XXCoder: is it annual plant where you have to plant new one, or is it one that lives for number of yearS>
07:13 PM XXCoder: ?
07:13 PM roycroft: it's an annual
07:13 PM XXCoder: interesting
07:13 PM roycroft: most vegetables are annuals or biennials
07:14 PM roycroft: for you folks on the other side of the pond i'm talking about courgettes
07:16 PM XXCoder: i want to have raw rhubarbs again
07:16 PM XXCoder: loved chewing on those
07:16 PM roycroft: well it's rhubarb season right now
07:16 PM roycroft: it's in all the markets here
07:17 PM XXCoder: few here. too sore to go still
07:17 PM XXCoder: my muscles heal way too flipping slow.
07:18 PM XXCoder: normal is 1-3 days. mine lasts a week or so
07:19 PM roycroft: i got a nice size bruise in my side when i got hit by the log the other day, and it's still a little sore, but i'm doing ok
07:19 PM XXCoder: around 15 years ago, I used to cycle every week. only once a week because soreness lasts that long
07:20 PM XXCoder: 25-50 miles
07:20 PM roycroft: 15 years ago i was cycling almost everywhere
07:20 PM roycroft: my car had blown up, and my van is crappy and gets 12mpg
07:21 PM roycroft: i decided not to buy another car, and went without one for about 5 years, just driving the van once or twice/week when i had to haul stuff
07:21 PM XXCoder: ouch heh
07:21 PM roycroft: i got a monthly bus pass, and got around on mass transit and my bike for a few years
07:21 PM XXCoder: i want to buy 3 wheeled bicycle once my money management settles down
07:21 PM roycroft: but then i started project managing fiber builds again, and needed a car for work
07:21 PM roycroft: so i got one
07:23 PM XXCoder: yeah usually goes like that
07:23 PM XXCoder: it'll be interesting to ride on 3 wheeled bicycle. been well over 30 years since last time I rode one
08:00 PM bjorkintosh: XXCoder, are you getting a velomobile? https://www.youtube.com/watch?v=cAcy7EVRpXc
08:01 PM XXCoder: lol interesting. I bet its expensive though'
08:01 PM XXCoder: i plan to get used 3 wheel so its bit over 100 usd
08:09 PM bjorkintosh: they're not cheap.
08:10 PM bjorkintosh: but they're more efficient than a regular bicycle.
08:10 PM Unterhausen: $10k-ish about
08:10 PM bjorkintosh: cost of a new small car.
08:10 PM Unterhausen: plus according to my friends that have one, you have to explain to cops that there is no motor
08:11 PM Unterhausen: I guess there are more expensive ones than that
08:12 PM bjorkintosh: you have friends who have one?
08:13 PM XXCoder: yeh thats around 10kish more than I can afford one
08:14 PM bjorkintosh: yeah but it's better than a car :-)
08:14 PM bjorkintosh: Don't ask why I don't have one though.
08:14 PM Unterhausen: two of them
08:15 PM Unterhausen: I don't have me because my spouse would kick me in the jimmies just for asking
08:15 PM bjorkintosh: because of the cost?
08:15 PM Unterhausen: and the space and the fact that she doesn't like me to buy things
08:16 PM Unterhausen: maybe if I got rid of an equivalent cubic volume of stuff
08:16 PM Unterhausen: granted, I should do that anyway
08:18 PM bjorkintosh: easily calculated!
08:23 PM Unterhausen: my program worked first time, some kind of record
08:24 PM Unterhausen: the people that made this temperature controller expected exactly nobody to write programs to control it remotely
08:25 PM Unterhausen: more useless knowledge to use up the few remaining neurons I had available
09:35 PM roycroft: i started clear coating my laser enclosure, and the latex paint underneath started cratering
09:35 PM roycroft: i guess that's what i get for being talked into buying premium paint
09:36 PM roycroft: i'm probably going to have to strip it all off and start all over agin
09:36 PM roycroft: i've used this exact same clear coat over latex paint dozens of times before
11:05 PM roycroft: well i am impressed - i think the 20w laser may be fine enough resolution for most of my work
11:05 PM roycroft: and it is wicked fast compared to the 5w
11:05 PM XXCoder: nice
11:05 PM roycroft: yeah
11:06 PM roycroft: the 5w has a resolution of 0.06mm x 0.06mm
11:06 PM roycroft: the 20w is 0.08mm x 0.10mm
11:07 PM XXCoder: so movement systems is different for axises?
11:07 PM roycroft: since it's going to be another week or more before the enclosure is finished i thought i should try the 20w laser head before it is too late to return
11:07 PM roycroft: no
11:07 PM roycroft: the beam is rectangular on the 20w
11:07 PM XXCoder: ahh
11:07 PM roycroft: most diode lasers have rectangular beams
11:07 PM XXCoder: not much you can do with that. still, resolution looks quite good
11:08 PM roycroft: i'm engraving a piece of jatoba at 400mm/s at 100% power right now and i'm getting a very nice etch
11:09 PM roycroft: with the 5w i had to go 80mm/s or slower
11:12 PM roycroft: i think i'll try a piece of poplar now
11:12 PM roycroft: and drop the power down to 70%
11:15 PM roycroft: weird - the poplar is not etching much at all
11:15 PM roycroft: i guess it's because it doesn't have much sugar in it
11:18 PM roycroft: now i'm going to have to find some ash to etch
11:19 PM roycroft: not much sugar or resin in ash, but there are a lot of tannins
11:23 PM XXCoder: interesting
11:23 PM roycroft: poplar is very unimpressive, but there are things i can do to make it engrave better, i think
11:24 PM roycroft: i don't anticpate needing to ever engrave poplar, though, so i won't spend much energy on it
11:25 PM roycroft: poplar gets hidden inside furniture, or if it's visible it gets painted
11:27 PM roycroft: well the ash was even worse
11:27 PM XXCoder: why is it disliked or something?
11:27 PM roycroft: it's soft, and unattractive
11:28 PM roycroft: but it's fairly stable, and very cheap
11:29 PM XXCoder: so thats why its used in hidden frame
11:31 PM roycroft: yes
11:32 PM roycroft: it also grows really straight, so it's usually not very knotty
11:32 PM roycroft: i'm running the ash now at 200m/s, half the speed of the jatoba, and doing two passes
11:33 PM roycroft: and i still think i'm not going to like it
11:34 PM XXCoder: could you cut out stuff out of those? rather than engrave
11:35 PM roycroft: i'll just have to improve the engraving proces
11:36 PM roycroft: if i make a water solution of borax and wipe that on the wood before i engrave i should get much better results
11:39 PM roycroft: it's getting late though, and i don't feel like mixing up a borax solution tonight
11:39 PM roycroft: i'll do that tomorrow
11:39 PM roycroft: i know the new laser head works, and it works very well
11:39 PM XXCoder: yeah good idea to not mix toxic stuff late
11:39 PM roycroft: it's not that toxic
11:40 PM roycroft: but it needs to be mixed in warm water to dissolve completely
11:40 PM roycroft: and then it needs to cool off, and when wiped on the wood it needs to dry
11:40 PM roycroft: so it's a process
11:40 PM roycroft: and i had to work all day, then work in the yard for a while, then attend a board meeting, then worked in the shop for a bit - i'm almost 15 hours into this day non-stop
11:41 PM roycroft: i even ran errands on my lunch break, and grabbed a bit to eat on the go
11:41 PM roycroft: the deal is that i need to engrave, and not too deep
11:42 PM roycroft: but i want the burn pattern on the engraving - seems odd, since most folks would rather get less burning
11:42 PM roycroft: but since it's a "brand", i want the burned look
11:42 PM roycroft: the ash engraves deeply but with almost no color
11:42 PM roycroft: the borax should give it the color
11:42 PM roycroft: and i don't want to paint the engraving after - that is not the look i want and it adds a couple steps
11:43 PM roycroft: and i just remember i still have laundry on the line, so i guess i'm not done for the day yet
11:46 PM XXCoder: ow
11:59 PM roycroft: now i'm done for the day :)
11:59 PM XXCoder: :)
