12:48 AM rue_shop2: ok that feed rate is really wrong
12:54 AM rue_shop2: I'v got time to make supper
12:54 AM rue_shop2: ... for the next 3 days
12:59 AM rue_mohr: the decorative bezel may work out
01:00 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170374.jpg
01:01 AM rue_mohr: oh I just caught an error
01:01 AM rue_mohr: glad I didn't run the other file first
03:52 AM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170382.jpg
03:53 AM rue_mohr: I'd still like to have had some scroll line work accent in there
04:21 AM rue_mohr: polprog, does my magnified image look half descent?
04:22 AM polprog: magnified?
04:22 AM rue_mohr: the 1 thou?
04:22 AM rue_mohr: :)
04:22 AM polprog: ah
04:22 AM polprog: yeah :)
04:23 AM rue_mohr: didn't know if that would just look too fake :D
04:23 AM rue_mohr: excited about the faceplate
04:23 AM rue_mohr: I set up pockets to countersink the knobs a bit
04:23 AM rue_mohr: so I have to cut them from the front,
04:24 AM rue_mohr: but I'd mirrored them to be cut from the back
04:24 AM rue_mohr: I hope I can zero it close enough
04:25 AM rue_mohr: I'm a bit worried everything wont work togethor
04:25 AM rue_mohr: guess I'll see
04:26 AM polprog: what are you cutting it in?
04:26 AM rue_mohr: could have gone with a smaller font, it looked ok in CAD
04:26 AM rue_mohr: lexan
04:26 AM polprog: ah
04:26 AM polprog: painted from one side?
04:26 AM polprog: thats how you make the transparent lines?
04:27 AM rue_mohr: masked and painted from the back
04:27 AM rue_mohr: the lines are 1mm CNC cut
04:27 AM polprog: ah
04:27 AM rue_mohr: it would have come out horrid if I'd masked it, cause I have to hand cut the masks
04:28 AM rue_mohr: cnc gives nice sharp lines AND some pseudo-depth
04:28 AM polprog: yesterday ive built a makeshift peak meter on the mcp6002
04:28 AM rue_mohr: It'll look lots better then I peel the protective stuff off
04:28 AM rue_mohr: 6002....
04:29 AM polprog: audio input is coupled into a 2.5v bias, the goes thru a 10x amp, then a perfect rectifier, then into a buffer that drives a 0-5mA indicator
04:29 AM polprog: the rrio opamp you told me to get
04:29 AM rue_mohr: op-amp!
04:29 AM polprog: although the rectifier isnt very precise...
04:29 AM rue_mohr: thoguht you were getting the 6004?
04:29 AM polprog: ah yes 6004 :D
04:29 AM polprog: my bad
04:30 AM rue_mohr: no, when I was doing a peak meter for my filer profiler I ran into all sorts of problems
04:30 AM polprog: maybe i mstook it for 6502 :D
04:30 AM rue_mohr: which is why I did a digital servo thing
04:31 AM polprog: https://www.ti.com/lit/ug/tidu030/tidu030.pdf
04:31 AM polprog: im using this, but 2.5V biasde
04:31 AM polprog: biased*
04:31 AM polprog: actually ill do some measurements...
04:41 AM polprog: ok, looks like it flips the polarity non symetrically
04:43 AM polprog: hmm, no, it flips at 2.5V okay
04:43 AM polprog: its jsut a glitch
04:44 AM polprog: 180us delay between the flip
04:44 AM polprog: maybe its the diode delay
04:44 AM polprog: or something
04:47 AM polprog: the recified signal at 20khz looks like crap
04:47 AM polprog: ill have to try the tl074
04:47 AM polprog: later
04:48 AM polprog: the needle jumps to the beat so thats okay
04:52 AM polprog: id love to calcualte it so that it has a max at zero db or sth
04:52 AM polprog: but this particular indicator doesnt have any scale at all
05:10 AM polprog: https://twitter.com/polprogpl/status/1307260519020212224?s=19
05:10 AM polprog: it has a "LOW"
12:14 PM rue_mohr: they did point out that its freq limited
12:50 PM MoonyMoon: what doing?
12:51 PM Tom_L: what u do?
12:52 PM MoonyMoon: me?
12:53 PM Tom_L: is u a u?
12:53 PM MoonyMoon: sometimes
12:53 PM MoonyMoon: I'm about to drink some tea and smoke some weed maybe
12:53 PM Tom_L: u still building a cnc?
12:54 PM MoonyMoon: getting to it almost never
12:55 PM Tom_L: that's sad
01:15 PM rue_mohr: I atleast welded my frame bits togethor
01:18 PM rue_mohr: oh no
01:18 PM rue_mohr: the solid carbon block I bought isn't solid
01:18 PM rue_mohr: damnit
01:18 PM rue_mohr: no, it is
01:18 PM rue_mohr: wtf
01:19 PM rue_mohr: ok, whatever
01:20 PM rue_mohr: paint is still setting on the faceplate
01:20 PM rue_mohr: I need to redo that last job file
01:20 PM rue_mohr: its mirrored
01:21 PM rue_mohr: ... and it shouldn't be
01:24 PM rue_mohr: I wonder how shipping on my programmer is doing
01:59 PM rue_shop2: Tom_L, whats the command to switch to relative move?
03:05 PM Tom_L: G90 G91
03:07 PM Tom_L: G90 is absolute, G91 is incremental (relative)
03:11 PM Tom_L: programmer for what?
03:11 PM polprog: rue_shop2: not sure what exactly limits it, diode recovery time? looks too slow for that.
03:12 PM polprog: not sure at what parameter of the opamp should i be looking at
03:12 PM polprog: it needs to quickly switch from a voltage follower to a -1 v/v inverting amplofier configuration
03:12 PM polprog: amplifier*
03:18 PM rue_mohr: it might be slew rate
03:18 PM rue_mohr: in that doc they talk about the limit, they show a 1kHz and the distortion
03:22 PM polprog: yeah its pretty bad at 20k
03:23 PM polprog: im pretty sure you could design a faster perfect rectifier with a more dead simple approach, analog switch, comparator and two signal paths for V<0 and V>0
03:23 PM polprog: but this one is interesting. i dont remember if the one i built on the TL074 was that slow
03:24 PM rue_mohr: but your not interested in a rectifier
03:24 PM rue_mohr: your interested in peaks
03:24 PM rue_mohr: how long do you want the peak valid for?
03:24 PM polprog: yes, but im interested in peaks in both polarities
03:24 PM polprog: wait, you just gave me an idea
03:25 PM polprog: i could make two peak detectors, one negative and one positive
03:25 PM polprog: ideally as short as possible, but that is simple
03:26 PM polprog: also
03:26 PM polprog: Selecting too large of a capacitor
03:26 PM polprog: will cause large distortion on the transition edges when the input signal changes polarity
03:26 PM polprog: my C7 is in the nf range (random parts tray pick) :(
03:26 PM polprog: their is pf range
03:26 PM polprog: may be that too
03:26 PM polprog: lets see what happens when i yank it
03:27 PM rue_mohr: oh, I thought you were going to say something about using a inverting and non-inverting amp
03:36 PM polprog: ok, it works better now
03:36 PM polprog: 670p
03:38 PM rue_mohr: k
03:39 PM zhanx_workshop_: so i called the before you dig number a week ago, they came out marked the lines left.
03:39 PM zhanx_workshop_: i borrowed a tractor to till in a garden and hit the water main
03:40 PM polprog: 2us glitch now
03:43 PM polprog: good enough
03:54 PM rue_mohr: zhanx_workshop_, where did they think it was?
03:55 PM polprog: call 811 after you dig and give them a piece of your mind
03:55 PM zhanx_workshop_: 100 feet west running the same direction, the county is out fixing it now, it was an illegal saddle tap by the last owner
03:57 PM zhanx_workshop_: which explains how he was able to water 4 acres of garden non-stop
04:02 PM rue_mohr: hmm
04:03 PM rue_mohr: you gonna be good without it?
04:03 PM zhanx_workshop_: well i am fixing the well next
04:03 PM zhanx_workshop_: it seems "borrowing" water was cheaper for the old dude
04:04 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170383.jpg
04:04 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170384.jpg
04:04 PM rue_mohr: face for my power supply is comming along
04:05 PM rue_mohr: almost ready to peel
04:05 PM rue_mohr: I kinda feel the leds should have been pocketed into the back ~1mm
04:07 PM polprog: wtf
04:07 PM rue_mohr: ?
04:07 PM polprog: firefox redirects me to www.ruemohr.org/....
04:07 PM rue_mohr: hahah
04:07 PM rue_mohr: can get get around it
04:08 PM rue_mohr: ?
04:08 PM polprog: it never done that before
04:08 PM polprog: and it breaks anyway, doesnt load
04:08 PM rue_mohr: ?
04:08 PM polprog: the net was very bad today
04:09 PM polprog: it doesnt resolve ruemohr.org for some reason now
04:09 PM rue_mohr: oh and its a virtual site
04:09 PM rue_mohr: so, you cant just go by IP
04:10 PM polprog: ** server can't find ruemohr.org: SERVFAIL
04:10 PM polprog: >:/
04:10 PM polprog: ill have to see whats wrong with the linksys box
04:10 PM rue_mohr: dns5.doteasy.com
04:10 PM polprog: its the dns and dhcp box here
04:10 PM rue_mohr: ^^ add to yer list
04:11 PM polprog: ;; connection timed out; no servers could be reached
04:11 PM polprog: wtf
04:11 PM polprog: thats dig @dns5.doteasy.com ruemohr.org
04:11 PM polprog: maybe it will go away
04:11 PM polprog: my ISP is pretty shit today, it was dropping remote desktop sessions all day long
04:11 PM rue_mohr: 65.61.198.13
04:12 PM rue_mohr: they dont take pings tho
04:12 PM polprog: same error
04:12 PM rue_mohr: creepy
04:13 PM rue_mohr: 8.8.8.8?
04:13 PM polprog: 8.8.8.8 works
04:13 PM polprog: good, added 8.8.8.8 to resolv conf
04:14 PM polprog: it will probably be overriten sooner or later but idc
04:14 PM polprog: yeah i saw these pics on twitter
04:15 PM polprog: not too shabby
04:15 PM polprog: i need to make some front panels
04:19 PM polprog: http://ruemohr.org/~ircjunk/tempimage/p1170364.jpg
04:19 PM polprog: why the 404 :D
04:19 PM polprog: also, i dig the monitor lightbox
05:07 PM zhanx_workshop_: well i pulled the well point, by hand by accident
05:07 PM zhanx_workshop_: i popped that top off and it started to fall in
05:07 PM zhanx_workshop_: 80+ feet deep
05:20 PM Tom_L: sand point?
05:20 PM rue_shop1: ?
05:20 PM Tom_L: sounds like z's having a bad day
05:22 PM rue_shop1: oh crap
05:22 PM rue_shop1: is the pump at the bottom?
05:22 PM rue_shop1: do you have a climbing barb you can get down into the pipe?
05:23 PM zhanx_workshop_: pump at the pump yes and i got it all out
05:23 PM rue_shop1: oh good
05:23 PM zhanx_workshop_: i caught it as it dropped
05:23 PM rue_shop1: metal or plastic pipe?
05:23 PM rue_shop1: oh good!
05:23 PM zhanx_workshop_: plastic 1"
05:23 PM Tom_L: so the water pipe was illegal?
05:23 PM Tom_L: black plastic?
05:23 PM rue_shop1: polprog, unit 404 in the apartment had the electrical room keys
05:23 PM zhanx_workshop_: the water pipe to the field was and yes black plastic to that
05:24 PM rue_shop1: cause the damn property management company NEVER remembers to supply the keys when they ask for repair jobs
05:24 PM zhanx_workshop_: they never fixed the well and the dude was friends with the county workers
05:24 PM rue_shop1: is it just a shot pump?
05:24 PM zhanx_workshop_: no clue my shoulders are fried
05:25 PM zhanx_workshop_: i will check it later
05:25 PM rue_shop2: from hand pulling up 80 feet of 1" poly?
05:25 PM Tom_L: figures
05:26 PM rue_shop2: hopefully the pump was on the bottom
05:26 PM zhanx_workshop_: with a pump at the bottom and the wiring yes, also the water in the column
05:26 PM rue_shop2: ouch
05:26 PM zhanx_workshop_: it never leaked out
05:26 PM rue_shop2: the WATER would be heavy
05:26 PM Tom_L: 2 pipes?
05:27 PM Tom_L: i helped a friend pull one once
05:27 PM rue_shop2: I think my cat got old last week
05:27 PM zhanx_workshop_: i counted 9 sections of 10' pipe but the top section was not full length
05:27 PM rue_shop2: wait, solid?
05:27 PM rue_shop2: not poly?
05:27 PM Tom_L: not the plastic roll?
05:28 PM Tom_L: my friends got a hole in one of the pipes about hafway down which was really odd
05:39 PM rue_shop1: ok, glueing to lexan
05:39 PM Tom_L: what kind of glue?
05:39 PM rue_shop1: yea
05:39 PM rue_shop1: soemthing that stays really sticky
05:39 PM Tom_L: :)
05:40 PM Tom_L: contact cement might
05:40 PM Tom_L: not many options there
05:44 PM polprog: market day tomorrow
05:44 PM polprog: ill go to sleep now
05:44 PM rue_shop2: hahah, the top edge of the orig material has all sorts of marks on it
05:49 PM zhanx_workshop_: pvc is dated from 1984-1988
05:49 PM zhanx_workshop_: pump was made in 85
05:51 PM Tom_L: some tie a cable or rope to the pump on those
05:52 PM zhanx_workshop_: gonna wax a rope and tie it on and replace the pipe
05:52 PM zhanx_workshop_: they used steel unions on the sch 80
05:53 PM zhanx_workshop_: rue_shop2, that is why also it was so heavy 1" sch 80 pipe
06:01 PM rue_mohr: plastic sch 80!?
06:03 PM zhanx_workshop_: just measured the pipe. its 20' sections and yes pvc 1" sch 80 pipe so i pulled 120 feet of pipe
06:11 PM rue_mohr: 5 gallons of water
06:13 PM Tom_L: ~40-50lbs
06:13 PM rue_mohr: probably a 50lb pump?
06:14 PM rue_mohr: and maybe 100+lbs pipe?
06:15 PM zhanx_workshop_: something
06:17 PM Tom_L: copper wire
06:20 PM zhanx_workshop_: 4 wires 12 gauge also
06:29 PM rue_shop2: cap on topside?
06:30 PM zhanx_workshop_: i broke the cap was the issue to look down the well
06:49 PM rue_mohr: oh I mean 4 wires, is the motor capacitor on the top
06:49 PM zhanx_workshop_: yep
06:55 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170387.jpg
06:55 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170389.jpg
06:55 PM rue_mohr: I was a bit uncertian, but I think this is what I wanted
06:58 PM zhanx_workshop_: that is nice
06:58 PM rue_mohr: I would have loved to have been able to slip in some subtle scrollwork infront of the black
06:59 PM zhanx_workshop_: when you shipping it to me
06:59 PM rue_mohr: haha
07:00 PM rue_mohr: too bad the neon plasma displays cant do dot mode
07:01 PM zhanx_workshop_: still looks epic
07:01 PM rue_mohr: I have to work out how to mount the switch and meters
07:01 PM rue_mohr: and indicators
07:01 PM zhanx_workshop_: u-brace on the rear of them
07:01 PM rue_mohr: the encoders were able to screw into the faceplate, I didn't think I'd be able to
07:02 PM rue_mohr: yea, I'm pondering a printed spacer and clamp off the bottom
07:02 PM rue_mohr: the switch shouldn't be too bad, Its got 4 screws holding it togethor, I can use two corners as bolt-thru to the bottom
07:03 PM rue_mohr: holding the faceplate on with the handles was an epic discovery
07:03 PM rue_mohr: :) no screws
07:04 PM rue_mohr: I'd also love fine graduation meters that were mirror backed
07:04 PM Tom_L: rue_mohr, where'd you buy that??
07:04 PM Tom_L: :)
07:05 PM rue_mohr: :)
07:05 PM rue_mohr: looking at it mocked up like that, I realized there should almost be a little logo in a corner
07:07 PM rue_mohr: I did that trick where ya make the faceplate larger and overhang it too
07:08 PM rue_mohr: oh, hmm
07:08 PM rue_mohr: next time maybe I can gut the meters and make a new faceplate that incorperates them both
07:10 PM rue_mohr: I wonder if the output should float
07:13 PM aandrew: rue_mohr: that faceplate is looking pretty spiffy
07:13 PM rue_mohr: thanks
07:14 PM rue_mohr: Its pointed out I need to set up silk screening
07:14 PM rue_mohr: I might have been able to do some extra stuff
07:14 PM rue_mohr: and easier
07:14 PM aandrew: so you literally took black tempra paint (like kid's paint) and painted it, used a CNC to very lightly route out where you want it silver so it's got nice clean edges, slop silver paint over the newly routed parts, then mill out anything clear and holes?
07:15 PM rue_mohr: no the clear bits were masked the whole time
07:15 PM rue_mohr: and spray paint
07:16 PM aandrew: oh I saw black tempra paint in one of the pics
07:16 PM rue_mohr: the large fill areas were masked in
07:16 PM rue_mohr: hmm
07:16 PM rue_mohr: I'm gonna build a photolog
07:21 PM Tom_L: damn gecko don't have pdf docs at least that i can find
07:21 PM Tom_L: 203v
07:22 PM rue_mohr: hu?
07:22 PM rue_mohr: 203V?
07:22 PM Tom_L: yeah
07:22 PM rue_mohr: volts of model number
07:22 PM Tom_L: it's online but no pdf
07:22 PM Tom_L: model
07:23 PM Tom_L: i found a word doc i can save to pdf
07:35 PM rue_mohr: ruemohr.org/~ircjunk/projects/newpower2/slide.htm
07:36 PM rue_mohr: there is a wack of stuff missing that I'v pulling forward from other supply projects
07:36 PM rue_mohr: that seems to be the body of everything so far
08:23 PM Tom_L: ok try again.
08:36 PM rue_shop1: ok, power switch is installed
08:36 PM rue_shop1: I have to mount the meters, the usb jack, and the main power heatsink
08:37 PM rue_shop1: then its just a matter of filling in the electronics
09:00 PM Tom_L: verified the gecko wiring
09:00 PM Tom_L: enable is NC so i think i can use that on the E-stop button
09:00 PM Tom_L: for the drivers
09:00 PM Tom_L: and the same on the vfd but on a separate leg of the relay
09:06 PM rue_shop1: is your e-stop 2 pole?
09:07 PM Tom_L: i'd have to look i don't think so that's why the relay
09:08 PM Tom_L: the relay is already in the control and unused currently
09:08 PM Tom_L: not a cheap chinese one
09:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Gecko_drives/gecko1.jpg
09:10 PM Tom_L: must be set for 3.5A ... 47k R
09:10 PM Tom_L: that's about what i thought it was
09:11 PM Tom_L: i could go up to 5A on these steppers but i see no need
09:12 PM MoonyMoon: Hay rue_mohr , how do you want I should give you this file?!?
09:16 PM Tom_L: fax it to him
09:17 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Gecko_drives/E-Stop1.jpg
09:17 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Gecko_drives/E-Stop2.jpg
09:18 PM Tom_L: single pole NC
09:19 PM Tom_L: MoonyMoon,!!! build a CNC dammit!
09:19 PM rue_shop1: MoonyMoon, maybe make up a good drive?
09:26 PM Tom_L: i should also wire the physical E-stop to the one on the pendant once this is all assembled
10:31 PM rue_shop2: hmm
10:32 PM rue_shop2: I never successfully remember about my pendant button when I'm panicing
10:32 PM Tom_L: i have it in hand when running an unknown program
10:33 PM Tom_L: so i have basically 3 sources for estop i need to account for
10:33 PM Tom_L: software, pendant and button on the control box
10:33 PM Tom_L: to control 2 sets of devices
10:34 PM Tom_L: stepper drivers and vfd
10:34 PM rue_shop2: I need to set up the other buttons for my cnc
10:34 PM rue_shop2: things like step stop run
10:34 PM Tom_L: and fix your buffer
10:34 PM rue_shop2: yea
10:34 PM Tom_L: yes
10:34 PM Tom_L: i wouldn't make it without my pendant
10:43 PM MoonyMoon: rue_shop2: there?
10:46 PM rue_shop2: yes
10:46 PM MoonyMoon: ok
10:46 PM MoonyMoon: try this
10:47 PM MoonyMoon: file transfer?
10:47 PM rue_shop2: google has a lot of space
10:47 PM MoonyMoon: did it work?
10:47 PM rue_shop2: make a fake google account and put them on a goodl drive
10:47 PM rue_shop2: your firewall is preventing the transfer
10:47 PM MoonyMoon: no gimme your email
10:47 PM rue_shop2: ugh
10:48 PM rue_shop2: just get a google drive set up
10:48 PM MoonyMoon: UHUHUHUHHU wefoufhqeibgvqwiv'[awiobgaw
10:48 PM MoonyMoon: 1 sec
10:50 PM Tom_L: paste.debian.net
10:50 PM MoonyMoon: https://drive.google.com/drive/folders/1EK7vn7HQcTBhA87kKaDECkPV1fhAvfvx
10:50 PM Tom_L: paste.ubuntu.com
10:51 PM MoonyMoon: rue said he wasnt into that :|
10:51 PM MoonyMoon: or did he?
10:53 PM MoonyMoon: Ah FUCK THE INTERNET!
11:01 PM rue_shop2: I'm never going to put anything important there
11:03 PM Tom_L: well, i wouldn't balance my checkbook there
