10:27 AM aandrew: ooh my i7 should be delivered today
10:42 AM aandrew: I feel a little foolish, I paid $45 for the i3-4GB-256GB SSD, my memory works in it just fine, my 1T SSD works in it, but the i5 I have did not, so I spent another $42 on the fastest/highest cache 3rd gen i7 that that system will take (my i5 is 4th gen which is why it doesn't fit)
10:42 AM aandrew: so I'm at $90 now and I could have got an i7-16G-10T (spinning rust) for that price but normal desktop
10:42 AM aandrew: it's fine, it's done, it'll work but whatever
11:08 AM rue_mohr: polprog, nice
11:16 AM rue_mohr: what is the sample rate?
01:16 PM rue_mohr: wow that eur:cad is steadily climbing
01:17 PM rue_mohr: I guess it'll start taking off when countries start selling their us bonds
01:17 PM rue_mohr: it'll be a hell of a storm
01:19 PM rue_mohr: I dont think anyone wants to start it, cause it'll still be a worldwide ripple
02:50 PM aandrew: yay, i7 arrived, installed, works exactly as it should.
02:50 PM aandrew: well Canada met with Japan and EU (France?) and started all together slowly selling US bonds which got Mr. Trump's attention
02:51 PM aandrew: he's trying to trash everything to cause interest rates to fall because the US has several trillion dollars worth of debt up for refinancing and if the interest rates drop it saves a lot of money
02:51 PM aandrew: only the world doesn't seem to be going along with the plan
02:51 PM aandrew: I believe this is the #1 reason why the whole "Governor Trudeau" and 51st state bullshit stopped within two weeks of Carney becoming interim PM
02:53 PM aandrew: hm, I found a 1T SSD and it has an apple filesystem on it but I can't access it
02:53 PM aandrew: it's got a weird error too, I wanted to take a closer look before nuking it
02:53 PM aandrew: this saves me $100 buying a spinning rust drive
02:55 PM aandrew: I honestly can't think of what apple filesystem might be on there unless it's my old hackintosh
02:55 PM aandrew: but even that would have been very expensive to buy a 1T SSD back then
03:06 PM aandrew: ah there we go
03:06 PM aandrew: $ sudo ./apfsutil /dev/sda2
03:06 PM aandrew: Volume 1 49683AC5-1AC5-4A78-9091-4A668DD7DC68
03:06 PM aandrew: ---------------------------------------------
03:06 PM aandrew: Role: Backup
03:06 PM aandrew: Name: TMCali (Case-sensitive)
03:06 PM aandrew: Capacity Consumed: 949786353664 Bytes
03:06 PM aandrew: FileVault: Yes
03:06 PM aandrew: Snapshots:
03:06 PM aandrew: it's just a backup disk
03:06 PM aandrew: now it's 1T of more storage on my dev machine
03:09 PM aandrew: now the eternal question... extend the existing vg on to the second disk, or use it as a second vg. the latter means I can remove it and still use it independently of the first drive
03:32 PM Tom_L: that's what i'd do
03:47 PM aandrew: yeah it's what I did do too
03:47 PM aandrew: still copying... 200G even across a pair of fast drives takes a while
03:49 PM aandrew: almost a million files
03:57 PM rue_mohr: see why I keep my pointless images small?
04:10 PM aandrew: nope over a million files now.. rsync keeps adding more
04:10 PM aandrew: rue_mohr: this is xilinx dev tools only
04:10 PM aandrew: 200GB
04:11 PM aandrew: rue_mohr: nope I do not get it.. keep 'em big, I love being able to see
04:11 PM aandrew: and I'm only too happy to facilitate that for you because you're one of the people doing what I consider the coolest stuff
04:11 PM Tom_L: yeah that's a big install
04:11 PM rue_mohr: ugh, HOW MANY (layers included) VIRTUAL MACHINES IS THAT!!!
04:11 PM aandrew: hm? this is no virtual machine
04:11 PM rue_mohr: aandrew, heh thanks
04:12 PM aandrew: this is that Dell SFF that I just dropped an i7 into and am copying Xilinx over to the new (old) SSD
04:13 PM aandrew: the VPS instance is running under KVM on OVH's hardware but there again it's just one layer of abstraction (at least the machine is, I don't know what their storage backend is)
04:13 PM aandrew: I'm running zfs on the VPS to split up/quota the individual bits so running out of room doesn't take down the system
04:14 PM aandrew: I usually run LVM on top of mdadm (that's what I'm doing on this SFF) but I specifically wanted zfs on the VPS because my mail and database stuff is there and want that to be compressed
04:14 PM aandrew: I have enough CPU but storage is expensive so I'm optimizing for that
04:15 PM aandrew: 46 minutes to copy 250GB that seems rather slow
04:16 PM aandrew: 1190800 files total
04:16 PM rue_mohr: ok, I took half a truckload of metal to the recycler and half a truck of recyclables to recycling.
04:16 PM rue_mohr: /dev/md0 3.6T 684G 2.8T 20% /files
04:16 PM rue_mohr: 192.168.9.12:/files 3.6T 136G 3.4T 4% /morfiles
04:16 PM aandrew: nice. do you get anything for the metal/recycling or is it all just to get the crap out of your area?
04:16 PM aandrew: I am disappoint, son
04:17 PM aandrew: you had a real opportunity there to mount that on /mohrfiles
04:17 PM rue_mohr: its just junk, but SOMETIMES, there is cool stuff I bring back
04:17 PM aandrew: no I mean do you get any money for bringing the stuff in
04:17 PM rue_mohr: no
04:17 PM rue_mohr: well batteries, copper and aluminum, otherwise no
04:17 PM aandrew: I am (or rather was, hard to do here in an apartment) an avid dumpster diver
04:18 PM rue_mohr: I took in a few batteries today but they were little ones and I didn't bother getting money or trade
04:20 PM rue_mohr: have you been following the power supply adventure I been on the past few days?
04:21 PM rue_mohr: ok, so, there is some welding to do
04:21 PM aandrew: no, been busy with a variety of things I'd rather not be busy with
04:21 PM aandrew: hah the xilinx installer creates .gitignore ... wonder how many clients were accidentally adding hundreds of GB to their git repos
04:21 PM rue_mohr: heh
04:26 PM aandrew: man fail2ban is a godsend
04:27 PM aandrew: the sheer number of VOIP attacks I see is astonishing
04:27 PM aandrew: ssh too but not NEARLY as many
04:27 PM aandrew: it's easily 100:1
04:28 PM rue_mohr: I wonder if their trying to get to a human or a service for make free international voip calls
04:28 PM aandrew: oh this is 100% automated attacks for greylist VOIP providers
04:37 PM rifraf: anyone can test topspin on an external hdd for me to confirm rpm with your accell?
04:39 PM rifraf: will make the app more useful for many things, have data capture now, and another app to make graphs from the accel data
04:40 PM rifraf: just need to sit phone on hdd or similar known spin rate device
04:51 PM polprog: rue_mohr: its 200MHz at 64 channels
05:17 PM rifraf: 2 seagate drive speeds, 7200 rpm and 5900, both spot on basically, https://desire3d.com/images/public/hddtest.jpg
05:23 PM Tom_L: you'd better hurry up with that test, all the rust is turning to chips
05:34 PM rifraf: what test?
06:03 PM rifraf: tom you have an external hdd?
06:08 PM rifraf: found issue with sampe rates, fixed here but need to see wat happens with another device now, currently your speeds are likely showing about 20% faster than they actually are
06:11 PM rifraf: with a hdd we can calibrate properly though
06:40 PM Tom_L: got the old lathe dialed in pretty decent...
06:41 PM Tom_L: out shaping some brass to a different shape
06:41 PM rifraf: nice one
06:45 PM rifraf: so glad i found this bug, i thought it was overspeed a bit but was in ballpark so left it
06:49 PM aandrew: I actually have no spinning rust anywhere here in the apartment in california
06:54 PM rifraf: aandrew any hdd?
06:54 PM aandrew: no spinning rust. All I have here are SSDs
06:54 PM rifraf: i see, ok :)
06:56 PM rifraf: i know rue would have at least 50, but he has no phone
07:32 PM Tom_L: ok seems to be working
07:50 PM Tom_L: rifraf, should i go with .400" or .375" for the body width?
07:50 PM Tom_L: guess i can always thin it some more
07:50 PM Tom_L: .400" it is
07:51 PM rifraf: wat feels good, between 8 and 10 mm is ok
07:51 PM rifraf: you mean the stem to hold onto right?
08:36 PM Tom_L: pics on the way
08:42 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/new_top1.jpg
08:42 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/new_top2.jpg
08:42 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/new_top3.jpg
08:43 PM rifraf: nice work, round those tips off nice and round, or very sharp, no flat spot
08:47 PM Tom_L: still wobbles horribly on the glass
08:48 PM rifraf: latest apk is, http://desire3d.com/images/public/topspin.apk
08:48 PM rifraf: flat bottoms will
08:49 PM Tom_L: it's 30deg then i rounded the tip
08:49 PM Tom_L: it's not flat
08:49 PM rifraf: k
08:49 PM Tom_L: i tried a sharp point with the other one and it was worse
08:51 PM Tom_L: i haven't polished the new one at all yet
08:51 PM rifraf: did you find external hdd? i need to make sure its calibrated
08:51 PM Tom_L: nope
08:52 PM rifraf: can you try?
08:52 PM Tom_L: i don't think i have any left
08:52 PM Tom_L: all ssd now
08:52 PM rifraf: fancy pants, i wish rue had a phone, he has every old hdd in canadia
08:56 PM Tom_L: i wonder if i need an update, the graph doesn't appear to be displaying the high numbers
08:56 PM rifraf: get an update, yes
08:56 PM Tom_L: is it up to date?
08:56 PM rifraf: alot changes
08:57 PM rifraf: as of about 10 minutes ago
08:58 PM rifraf: i know its good to test with 7200 rpm drive, not much above that though
08:58 PM rifraf: and csv saves now, good raw data to do anything with
09:00 PM rifraf: does your lathe have vfd that shows rpm? you can check now with app, tape it on the motor or near to it
09:00 PM Tom_L: no
09:00 PM Tom_L: it's 100 yrs old sir
09:00 PM rifraf: well now bring it into 2025, put phone on motor and tell me what rpm it is
09:00 PM Tom_L: the graph doesn't appear to be showing all the numbers it should be
09:01 PM rifraf: it does here, try for a bit then send screenshot
09:02 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/S25_graph.jpg
09:03 PM rifraf: yeah yuck, exit and go back in
09:03 PM rifraf: you have been in the settings?
09:04 PM Tom_L: i set the top dimenstions, material and 200 bottom 8000 top for the graph
09:04 PM Tom_L: it remembers that
09:04 PM rifraf: ok and now stay out of settings, and restart app
09:04 PM Tom_L: dunno if it's using it correctly
09:04 PM Tom_L: i did but it remembers them
09:05 PM rifraf: yes the MOI and KE look right, but there are some crazy high chart numbers, thats why high KE,
09:07 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/S25_graph2.jpg
09:08 PM Tom_L: this top isn't alot better than the previous one
09:08 PM rifraf: are you getting good spins? or find an object thats spins at a kinda known speed?\ the graph is not displaying well at all though, i will try fix
09:08 PM Tom_L: it wobbles a bit
09:09 PM Tom_L: on the glass the vibes are in the 800 range
09:09 PM rifraf: i will get a screenshot of this next spin and show you, are you using the Snap button?
09:09 PM rifraf: 800 is pretty high
09:09 PM Tom_L: i should go polish the top some
09:10 PM rifraf: just the tip
09:11 PM rifraf: make it a perfect spherical shape
09:11 PM rifraf: no matter how sharp, you can make it sharp, but then still round it like a ball
09:12 PM rifraf: a point digs into one point of the glass and does not let precession happen naturally
09:15 PM Tom_L: i found that out on the first one
09:16 PM Tom_L: i may chuck it back in the lathe and look it over a bit
09:16 PM Tom_L: may be afk a bit
09:17 PM rifraf: ok, but while you there put app on your lathe motor
09:17 PM rifraf: and every other motor in the shed
09:18 PM Tom_L: 4 jaw so it takes me longer
09:18 PM Tom_L: maybe
09:52 PM Tom_L: the lathe rpm is 1725 and it registered 1560
09:56 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/lathe_rpm.jpg
09:56 PM Tom_L: notice the numbers left side graph aren't showing the whole number
10:02 PM rifraf: yep, can reduce font size for you
10:03 PM Tom_L: is the math off since the lathe motor was more than the graph said?
10:03 PM rifraf: whatdid it say, and do you have the updated version?
10:04 PM Tom_L: i just loaded it and ran it on the lathe motor
10:04 PM rifraf: and?
10:04 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/lathe_rpm.jpg
10:04 PM rifraf: maybe there is a 1 missing?
10:04 PM Tom_L: that's what i said
10:05 PM Tom_L: but the rpm shows at the bottom and it's off
10:05 PM Tom_L: 1725 is what it should be
10:05 PM Tom_L: it's stamped on the motor
10:05 PM rifraf: good test
10:05 PM rifraf: at 60 hz power i imagine
10:05 PM Tom_L: yup
10:05 PM Tom_L: is yours 50?
10:07 PM rifraf: yep
10:07 PM rifraf: ok file updated
10:07 PM Tom_L: so i've made 2 tops and think i will wait for rue to catch up
10:07 PM rifraf: he is very slow
10:07 PM rifraf: its addhd i think
10:08 PM rifraf: says the man who has been spinning a top for over a year
10:08 PM Tom_L: i will run the lathe motor test with the new stuff if you think it will make a difference
10:09 PM Tom_L: but you have an end goal and i don't
10:09 PM rifraf: i am gettin some nice lines now
10:09 PM rifraf: you can save watever, are you using the sanp button?
10:10 PM rifraf: the files should end up in screenshot folder
10:10 PM Tom_L: still can only see 3 digits on the graph
10:10 PM rifraf: ok will make graph skinnier
10:11 PM Tom_L: and 1.5 on the right side
10:11 PM Tom_L: the rest is shaping up good
10:11 PM Tom_L: can see most of everything now
10:13 PM Tom_L: i may try to round the bottom of the top and cup the inside. may just be asking for trouble
10:13 PM rifraf: ok reduced graph size, you can download again
10:15 PM Tom_L: better
10:15 PM Tom_L: on your top, what's the distance from the bottom of the base to the tip?
10:16 PM Tom_L: 9.3mm here
10:16 PM Tom_L: and 6.4mm on the first top
10:16 PM rifraf: they vary, and the shapes are not flat, but around 5 to 8mm
10:17 PM Tom_L: is 9.3 too much?
10:17 PM rifraf: no
10:17 PM rifraf: there is no right or wrong
10:17 PM Tom_L: i left it long in case i needed to trim it down
10:17 PM Tom_L: i'm finding quite a few wrong
10:18 PM rifraf: thats why there is no rule for makng a top, i can just give you advice
10:18 PM rifraf: there are better ways to do things thats for sure
10:19 PM rifraf: thats why a fast spinning top is way different to a long spinning top
10:20 PM rifraf: and you have to combine both for the best experience
10:20 PM rue_shop4: ok! did some welding
10:20 PM Tom_L: you weld up a top?
10:21 PM Tom_L: i made on on the lathe i fixed
10:21 PM rifraf: no i press fit them now
10:22 PM Tom_L: rue_shop4, http://tom-itx.no-ip.biz:443/~webpage/rifraf/new_top3.jpg
10:22 PM Tom_L: did you fix the rpm issue?
10:22 PM Tom_L: should i test the lathe motor again?
10:22 PM rifraf: yes you must
10:23 PM rifraf: rue_mohr hdd tests, https://desire3d.com/images/public/hddtest.jpg
10:25 PM rue_shop4: nice tom!
10:25 PM rue_shop4: why you using 5800rpm drives? 7200 dude!
10:25 PM rue_shop4: :]
10:26 PM rue_shop4: oh, wrong value
10:26 PM rue_shop4: haha is 7200 good!
10:26 PM rifraf: i was testing what i had, one was 7200, other was 5900
10:26 PM rue_shop4: 5900?
10:26 PM rue_shop4: huh
10:26 PM rifraf: is 2 drives on that graph
10:26 PM rifraf: i switched out half way
10:27 PM rifraf: yes a seagate drive, i asked my ia, its right at 5900rpm
10:27 PM rue_shop4: I made a box drag
10:27 PM rue_shop4: for excating the soil under the house
10:27 PM Tom_L: now it shows around 1500 rpm
10:27 PM rifraf: The Seagate Barracuda LP 2TB (model often something like ST32000542AS) is a 3.5-inch SATA hard drive from the “Low Power” series, aimed at reducing energy consumption while still offering decent storage capacity.
10:27 PM rifraf: Here are the general speed specs:
10:27 PM rifraf: Rotational speed: 5900 RPM (not 7200 like standard Barracudas)
10:28 PM rue_shop4: well
10:28 PM rue_shop4: some of the 7200 couldn't processes full stream speed
10:28 PM rue_shop4: so they would take a few passes to get the data they were supposed to off a track
10:28 PM rifraf: rue_mohr how cool is the app for getting it correct though?
10:28 PM rue_shop4: so, I had a new 5800 rpm drives that raw transfer rate beat some 7200rpm drives
10:29 PM rue_shop4: thats supoer cool rif!
10:30 PM rifraf: so rue, this is your new hdd tezster, with full data logging, so you can analyse, i have already started on a new app to use the saved data
10:30 PM rifraf: Tom_L 1500 rpm still not right
10:30 PM rue_shop4: :]
10:31 PM rue_shop4: I need to make a bidirectional winch for operating the drag
10:31 PM rifraf: if only you had an android from this decade :/
10:31 PM Tom_L: where does your button save the screenshots?
10:31 PM Tom_L: not in screenshots....
10:31 PM rifraf: Tom_L should be the screenshot folder
10:31 PM rifraf: used to be the app folder but too hard to get to
10:31 PM Tom_L: should be is the key word
10:31 PM rue_shop4: I need food, then gonna hammer away on a 3.3V supply for this remote
10:31 PM Tom_L: i'm not finding that one
10:32 PM rue_shop4: think I will just try 3 1.5V batteries on a LM1117-3.3
10:32 PM Tom_L: it shows in images but not in files
10:32 PM rifraf: hrm ok,but you can see them somehow?
10:33 PM Tom_L: yeah but i dunno where they are
10:33 PM rifraf: ok cool, thats a great start
10:34 PM rifraf: try look for properties
10:34 PM Tom_L: they're not in internal storage where they should be
10:35 PM Tom_L: i emptied that folder and they're still there
10:35 PM rifraf: not sure sorry, will be a phone difference thing
10:35 PM Tom_L: that's where they should be though
10:35 PM rifraf: that i can only fix once we find them
10:36 PM rifraf: mine are in pictures / screenshots i think
10:36 PM Tom_L: i took a screen shot of it if you wanna see it
10:36 PM Tom_L: these go in internal storage/DCIM/screenshots
10:36 PM Tom_L: when the phone does it
10:37 PM rifraf: ok, i think it mat be a permissions thing, i had to use an android app to see the csv file before
10:37 PM rifraf: now mine go in the same place, but i guess not on yours
10:38 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/lathe_motor2.jpg
10:38 PM Tom_L: screen shot of a screen shot :)
10:39 PM rifraf: nice, at least its consistant, not we need t calibrate, i thought this may happen
10:40 PM rifraf: 1500 is such a perfect number though
10:41 PM Tom_L: perfect but wrong
10:42 PM rifraf: meant to be?
10:46 PM Tom_L: makes me happy the lathe works better now
10:47 PM rifraf: awesome, see a good weekend
10:47 PM Tom_L: sharpened up some carbide cutters too
10:53 PM Tom_L: bedtime here
11:07 PM Tom_L: wow i can still get parts for that lathe
11:09 PM Tom_L: https://www.amazon.com/Crossfeed-Craftsman-101-21200-101-21400-lathes/dp/B097GQ97VX?gQT=1
11:09 PM Tom_L: i had one off another vertical cross slide attachment
11:09 PM Tom_L: but the original was shot
11:13 PM rue_shop4: wow
11:13 PM rue_shop4: its a fail
11:13 PM rue_shop4: 3 AA batteries into a LM1117-3.3 wont generate 3.3V at 80mA
11:14 PM rue_shop4: maybe I should use a 12V battery and a stepdown
11:14 PM Tom_L: D battery
11:15 PM Tom_L: there must still be quite a few of these lathes out there for parts to be that available
11:19 PM rifraf: hundreds for sure
11:19 PM rifraf: especially if you got made in usa
11:19 PM Tom_L: i should figure out what model i have
11:20 PM Tom_L: atlas / craftsman
11:23 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Z_Axis_Pulley.jpg
