21:42:33 <Lemon> its not rare for usb ports to fail honestly
21:42:33 <rust_collector> it is getting old, sort of, and it has had a pretty rough life. but it seems like it uses 2 different usb thingies, since the front ones kept working...
21:42:33 <rust_collector> it would be weird if both thingies failed within a few days
21:42:33 <Lemon> usually the front ones are connected on a header, on the bottom of the mobo
21:42:33 <rust_collector> well, yes
21:42:33 <rust_collector> i sort of like this machine. it is pretty compact-ish, and it does more than I need.
21:42:33 <Lemon> hmmm im at like 152k samples and its still going well
21:42:33 <rust_collector> still at 3.75ksamples/second?
21:42:33 <Lemon> yeah
21:42:33 <Lemon> 3,75 per second
21:42:33 <rust_collector> blah
21:42:33 <rust_collector> 3.75k would be more more
21:42:33 <Lemon> you need a hell of an adc lol
21:42:34 <Lemon> I think the max mine can do, if I go down to 12 bits, is 240 sps
21:42:34 <Lemon> which is a ton
21:42:34 <Lemon> and not useful for temperature
21:42:34 <Lemon> 3.75 is a bit easier to read
21:42:34 <Lemon> the screen refresh is nicer
21:42:34 <Lemon> but I could plot one per second
21:42:34 <rust_collector> right
21:42:34 <Lemon> also 3.75 helps drawing a nicer chart
21:42:34 <Lemon> quicker
21:42:34 <Lemon> not quicker but
21:42:34 <Lemon> its just more defined
21:42:34 <Lemon> also the zooming capability is neat
21:42:34 <rust_collector> yes, that sounds like a good feature
21:42:34 <Lemon> lets see how many samples I can take before it starts lagging
21:42:34 <rust_collector> https://imgur.com/a/trCQxaf
21:42:34 <Lemon> I'll add an option to chose how many samples you want
21:42:34 <rust_collector> why should it start lagging?
21:42:34 <Lemon> like the regular 3.75/s, or 1 per sec, per minute etc
21:42:34 <rust_collector> sure
21:42:34 <Lemon> because theres thousands of points drawn on the chart
21:42:34 <Lemon> im using fastlines, which seems way better
21:42:34 <Lemon> with spline, after 6k samples it was lagging
21:42:34 <Lemon> MS chart perks I guess
21:42:34 <rust_collector> drawing points should not take all that much time? well...
21:42:34 <Lemon> yeah I guess its badly optimized
21:42:34 <rust_collector> oh well. it weerks
21:42:34 <Lemon> yeah if it can hold at least 24h it would be nice
21:42:34 <Lemon> right now I know that it can hold more than 48h with 1 sample a sec
21:42:34 <Lemon> which is fine
21:42:34 <rust_collector> yep, that should be plenty
21:42:34 <rust_collector> unless you are measuring explosives or something
21:42:34 <Lemon> well we cant have everything
21:42:34 <rust_collector> I think the uno is a nice little board. just right size. it should be bigger, but the proportions is right
21:42:34 <Lemon> I think I'll do something like : 3.75 sps for 24h, 1sps for 72h, and 10s/minutes for 72h+
21:42:34 <Lemon> its neat yeah

21:59:19 <rust_collector> I really hate not being on the ground. But I sort of like people jumping around on roofs
21:59:21 <Lemon> are you batman when not on irc ? :>
21:59:41 <rust_collector> spiderman, thankyouverymuch
22:00:58 <Lemon> I always wanted a lenovo x220 or x230, and now I kinda want it as a data logging machine
22:01:16 <Lemon> I can leave it all night for example, where my workstation makes too much noise and consume a lot of power
22:01:22 <Lemon> https://www.ebay.fr/itm/Lenovo-X220-working-laptop-Intel-i7-2640M-4GB-Windows-10-1-bad-USB-500GB/324160862644?hash=item4b797e39b4:g:iVwAAOSwZRFetoD1#viTabs_0
22:01:44 <rust_collector> nah. those are nice to use. you need a shitty little desktop
22:02:55 <Lemon> noooo
22:03:04 <Lemon> I will use it for other things probably
22:03:23 <Lemon> like taking it to my bedroom for a movie, or to someones house if I need to fix his computer
22:03:42 <Lemon> a ssd and those are still pretty nice machines
22:04:22 <rust_collector> sure, but you still need a crappy old desktop sort of machine for logging. Just buy an x series, and use it as a laptop
22:05:47 <Lemon> https://www.ebay.fr/itm/313054981047
22:05:49 <rust_collector> maybe one of those little "media pc" things, they are ie laptops, in a tiny box
22:05:52 <Lemon> why that
22:05:57 <Lemon> I can use the lenovo
22:06:26 <Lemon> I asked the seller for pictures
22:06:28 <rust_collector> I know you can use the lenovo. i am using a lenovo right now...
22:06:28 <Lemon> to see the defects
22:06:35 <Lemon> I love lenovos
22:06:39 <Lemon> I always wanted one of those lil machines
22:06:55 <rust_collector> yep, they are neat
22:07:00 <Lemon> if its fine enough, for 130 euros delivered its perfect
22:07:13 <Lemon> add 30-40 euros for a ssd, or maybe not if I take the one off my workstation as I have two
22:07:16 <Lemon> and I use it for vms
22:07:21 <Lemon> which I dont really use at all those days
22:07:45 <rust_collector> just wait, you will use it all the time, so you will need a second machine soon enough
22:08:02 <Lemon> maybe, who knows !
22:08:22 <rust_collector> I like the x series that did not have the touchpad
22:09:39 <Lemon> yeah I rarely use it anyway
22:09:57 <rust_collector> I just disable it
22:10:15 <Lemon> ho I leave it on in case I need it but I'll probably plug a mouse
22:10:21 <rust_collector> hmm, how about using a thin client for logging?
22:10:50 <rust_collector> on a lenovo, you have the clit, you do not need mouse or touchpad
22:10:59 <Lemon> like a rpi ?
22:11:04 <Lemon> good ol clit
22:11:51 <rust_collector> no, like a thin client. but ok, a rpi4 would be good, because then I can send of these cases I have no use for
22:12:05 <Lemon> what do you mean by a thin client ?
22:12:12 <Lemon> like a vm on my workstation ?
22:12:39 <Lemon> what I like with the lenovo is that its small, quiet and not power hungry
22:12:44 <rust_collector> no. the physical thing...
22:12:48 <rust_collector> https://www.ebay.fr/itm/HP-T610-plus-Thin-Client-16GB-Flash-4GB-DDR3-AMD-G-T56N-USB-3-0-SATA/333350101466?_trkparms=aid%3D1110004%26algo%3DSPLICE.COMP%26ao%3D1%26asc%3D20200220094952%26meid%3Da3bc5a09315b440d81f363b446993573%26pid%3D100008%26rk%3D6%26rkt%3D12%26mehot%3Dpp%26sd%3D143575478491%26itm%3D333350101466%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3Ddefault%26brand%3DHP&_trksid=p2047675.c100008.m2219
22:13:02 <rust_collector> like that one, just maybe not exactly that model
22:13:28 <Lemon> ha well its not that practical compared to the lenovo
22:13:34 <Lemon> I need an external screen, keyboard etc
22:13:48 <rust_collector> not if you just want logging.
22:13:53 <Lemon> and I probably get worse performance for the price
22:14:01 <Lemon> yeah but I want to be able to tweak it when I want
22:14:09 <Lemon> plugging a screen+kb etc is a pain
22:14:18 <Lemon> the lenovo is a small foot print
22:14:19 <rust_collector> sure, but then you have a laptop to use when you are logging things also
22:14:22 <Lemon> with everything needed
22:14:32 <Lemon> I have the main workstation :>
22:14:55 <rust_collector> just remote into it, from whatever machine, or phone, or..
22:15:03 <Lemon> yeah true
22:15:09 <Lemon> but the lenovoooooooo
22:15:11 <rust_collector> yes, but you did not want to use the workstation for this
22:15:11 <Lemon> its cute !
22:15:40 <rust_collector> yes, I think I told you to get one, but you will also need a small desktop of some kind
22:15:53 <rust_collector> just wait and see
22:15:58 <Lemon> but I can perfectly log shit with the lenovo while using it
22:16:09 <Lemon> but yeah in the rare cases when I need to take it out the home you are right
22:16:15 <Lemon> I'll see later for that
22:16:18 <rust_collector> not while you are at some other guys house fixing his confuser
22:17:26 <rust_collector> well, if you end up getting a pi, try to get a 4, so I can get rid of this case I have flying around in my back seat
22:18:17 <Lemon> haha yes I know you want to get rid of them
22:18:26 <Lemon> but I think my father had a eeepc thin client somewhere
22:18:32 <Lemon> idk if its powerful enough but well
22:18:42 <Lemon> my thermometer datalogger needs some ressources
22:18:48 <Lemon> lemme see
22:18:49 <rust_collector> it does not take much power to log stuff, I think
22:19:28 <Lemon> 75mb of ram and 1% of my 64 logical cores
22:19:35 <Lemon> yeah should be fine
22:19:37 <rust_collector> yeah
22:19:58 <rust_collector> and... what os is this? /?
22:20:06 <rust_collector> 7?
22:20:25 <Lemon> win 10 on the workstation
22:20:30 <rust_collector> ok
22:21:18 <rust_collector> I think windows likes to "reserve" a bit more ram just in case, or something. it would probably use less, if it had to
22:21:41 <Lemon> yeah
22:22:11 <Lemon> I dont really realise how taxing stuff is on my workstation, with 32c/64t, 64gb ram, a nvme ssd and a gtx 1080
22:22:14 <Lemon> nothing lags
22:23:47 <rust_collector> I have used one of those little thin clients as a desktop. running at 389mhz, and with 105mb of ram to use. firrefox was not fun, but in general, it ran ok
22:24:28 <Lemon> yeah nowadays at least 2c/4t at 2.5ghz, and 4gb ram is the minimum
22:24:34 <Lemon> for win 10
22:24:41 <rust_collector> well....
22:24:43 <Lemon> if you go linux, pretty much anything is fine
22:24:51 <rust_collector> not these days
22:25:10 <rust_collector> unless you dig out some weirdo mini distro
22:25:20 <rust_collector> it is getting bloated
22:26:05 <Lemon> yeah true
22:26:06 <Lemon> ho btw
22:26:10 <Lemon> I still want a receiver !
22:26:26 <rust_collector> did you see the pic of mine?
22:26:39 <Lemon> I dont really know what to look for, but I want something where I can listen to most stations out there
22:26:44 <Lemon> no ! show me show me
22:27:19 <rust_collector> most radios can play most stations, because most stations are in the band radio uses?
22:27:37 <Lemon> yeah I guess but maybe some receivers got limited bands or idk
22:27:43 <Lemon> I really dont know much
22:27:51 <Lemon> I guess I need a am/fm receiver of the 90s ?
22:27:54 <Lemon> there were looking neat
22:27:57 <Lemon> they
22:34:24 <rust_collector> https://imgur.com/a/weHZANO
22:34:55 <rust_collector> it takes up a good chunk of space, any you might want to add a leg to your bench
22:35:08 <Lemon> perfect thats the kind of thing I thought about
22:35:27 <Lemon> I saw some technics, sonys etc for around 40-50 euros delivered
22:35:42 <rust_collector> mmhmm
22:35:51 <rust_collector> plenty of radios out there
22:36:42 <rust_collector> this one was made some time between -77 and -83
22:37:08 <rust_collector> I have not found any date on it, but I have not had it open yet
22:37:46 <rust_collector> they have their phone number on it, but not the production date, or serial number or anything
22:38:09 <Lemon> give them a call
22:38:22 <rust_collector> yeah, they do not exist any more
22:39:49 <rust_collector> and, you would have to invent the number, as it is a bit shorter than what we use now
22:40:10 <Lemon> then go back in time, huh
22:40:55 <rust_collector> my time traveling lathe is not here yet... It will be here in just a few years ago
22:42:06 <rust_collector> maybe next time
22:42:25 <coppice> lathes are nice tools to have around
22:42:31 <rust_collector> yessss
22:43:00 <rust_collector> I am still debating if I want a mill or a lathe first
22:43:00 <coppice> there's something deeply satisfying about carving wood on a lathe
22:43:08 <rust_collector> meh
22:43:24 <rust_collector> well, ok, but I am a metal sort of guy
22:43:56 <coppice> its wonderful positioning a chisel, and seeing shaped wood appear in front of you
22:45:07 <rust_collector> a second good thing about woodturning things, is that it is not so insanely expensive
22:45:17 <coppice> same with metal really, but metal takes too long to carve to get that immediate feedback as you work
22:46:50 <rust_collector> I think I just like the nice finish, (when you get a nice finish) and that you can make it so very accurate...at least until someone breathes on it, and it grows 1/1000mm
22:47:38 <rust_collector> precise, maybe. it is pretty late for my brain to be up
22:49:09 <rust_collector> I do like people making things out of wood, it is a skill. But I just prefer metal for myself.
22:50:12 <Lemon> I prefer human bones
22:51:16 <rust_collector> I used to chat with a guy from just outside atlanta. he made a bass guitar, and a set of nice dining chairs. the chairs had... "butt shape" and he did that just with scrapers and sanding. but they did look pretty close to the same
22:52:27 <rust_collector> now, bones are pretty stable, i guess
22:56:28 <coppice> fat arse shaped, or cute little bum shaped?
22:56:59 <rust_collector> well, atlanta... somewhere in the middle, i would say
23:25:21 <EEVBlog> New EEVBlog Retweet: Uncle Duke: I rocked all the way down here for this bullshit? https://t.co/3t8d3CYNVi
23:39:14 <coppice> nice
23:41:46 <rust_collector> I wonder if I should add some kind of heating in the garage. I have to replace the siding in a few years, so I will probably insulate it then.
23:43:44 <rust_collector> But I sort of think I should install the stove now, because it is getting harder and harder to do that legally.
