01:26 AM Loetmichel: mornin'
01:32 AM Loetmichel: meh. Weather kaput. i had ICE on my windshield this morning... in germany and mid may?!?
01:43 AM miss0r: we had hail this morning...
01:43 AM miss0r: forget global warming.. With all this inactivity coupled with the corona virus, we now have global chilling :P
02:29 AM net|: miss0r why spread ignorance at near lightspeed on irc ? thats not really what its ment for you know ?
02:29 AM net|: let god do his work and when it feels like you have to say about it just pinch yourself
02:31 AM net|: sometimes when you get weird snow its because they needed more albedo and cloud cover
02:36 AM net|: truth is the moon and earth might be pulled really far out from april 20th's jupiter and saturn alignment
02:51 AM CaptHindsight is now known as CarpetDiem
03:11 AM Deejay: moin
03:16 AM miss0r: net|: Sarcasm realy translates poorly on IRC...
03:17 AM lmat: Rab: Wow, that mesanet.com is a pretty serious set of equipment. I like their no-bs approach. This is the card, this is what it does, this is how it connects, oh, and the firmware is open source!
03:18 AM SpeedEvil is now known as Guest3959
03:57 AM lmat: What's your response to https://crevis.us/product/gt-1238/ plus https://crevis.us/product/gl-9089/ ? To me it feels like significant overkill to get digital inputs into a computer (even in an industrial setting), no?
04:04 AM Loetmichel: Hmm. I know there are small HDMI adapters that do a 90°(horizontal to straight up). Anybody seen some that do a 180°? (maybe 1" tall)
04:04 AM Loetmichel: <- has to plug in a HDMI converter into a Display but only have 20mm where the HDMI "outlet" is on the display, so i have to go "up and reverse" to have the converter hovering over the PCB
04:05 AM lmat: Loetmichel: I can't picture that... You have a PCB with HDMI female on it with only 20mm clearance. Sounds like 90 degrees is a good way to go?
04:20 AM Loetmichel: i only have 20mm clearance in x AND z
04:21 AM lmat: Loetmichel: 180 degrees? That doesn't make sense... That would put the cable back through the connector...or something.
04:22 AM XXCoder: lmat: " 1" tall "
04:22 AM lmat: Loetmichel: Is one of these what you need?https://imgur.com/4dju2o7.png
04:23 AM XXCoder: there is 180 degree connectors yeah. one of em comes with screen for rpi4 for example
04:24 AM Loetmichel: Lmat: http://www.cyrom.org/palbum/main.php?g2_itemId=17812&g2_imageViewsIndex=1
04:24 AM Loetmichel: see the problem?
04:24 AM Loetmichel: i want to get rid of the black extension
04:24 AM XXCoder: Loetmichel: trying to finmd it
04:24 AM Loetmichel: and have the converter (gold) hovering over the PCB
04:25 AM Loetmichel: lmat: i could prolly use two of the pearstone things
04:25 AM XXCoder: 2 opf https://www.aliexpress.com/i/32667882335.html ? cant find one im tlking abouy
04:25 AM Loetmichel: just looked at your picture
04:26 AM XXCoder: FOUND IT!!
04:26 AM XXCoder: https://www.waveshare.com/wiki/3.5inch_HDMI_LCD
04:27 AM XXCoder: ook at connector twhat comes with it
04:28 AM Loetmichel: XXCoder: that would be ideal... if it had a female at one end
04:29 AM Loetmichel: probably the best idea to use two 90 plugged into each other
04:29 AM XXCoder: if cant find i guess can use gender change with it
04:33 AM sensille: XXCoder: wandering inn reminds me of New Era Online series (Life Reset)
04:33 AM XXCoder: yeah? cool. i LOVE wadering inn though
04:34 AM sensille: just listened to the first hour or 2 yet
04:35 AM XXCoder: damn we was quoted 7000usd for simply patching sewer pipe.
04:35 AM XXCoder: we want to replace whole section of pipe so thats out lol we'll do it ourselves
04:39 AM XXCoder: doctors found a way to protect people from covid. finally
04:39 AM XXCoder: eat 5 cloves of garlic everyday.
04:39 AM XXCoder: it does completely nothing to virus, but it helps people properly follow social distancing.
04:41 AM Loetmichel: hihi
04:42 AM sensille: XXCoder: doesn't help if everyone does it, though
04:42 AM XXCoder: lol
04:43 AM XXCoder: ohboy
04:43 AM XXCoder: russia is #2 now
04:43 AM XXCoder: crazy
04:44 AM XXCoder: will take a long while to overtake usa tho
04:54 AM lmat: Loetmichel: Ah, I see. 180 degrees as you said!
04:54 AM lmat: Loetmichel: Yeah, two 90s :shrug:
05:08 AM JT-Cave: moonring
05:09 AM XXCoder: hey ring of moon
05:17 AM miss0r: Junctionbox for the landrover is complete.. https://imgur.com/a/TR4FPS3
05:17 AM miss0r: I wish I had double the space to make it, that would've made me able to make it look neat... But it is functional as is.
05:18 AM miss0r: and I have a 10-page circuit diagram detailing everything
05:20 AM JT-Cave: PVC
05:20 AM JT-Cave: Panel Very Crowded
05:20 AM XXCoder: lol
05:21 AM miss0r: yeah....
05:21 AM miss0r: :]
05:51 AM JT-Cave: this is the machine I'm going to automate https://gnipsel.com/images/customers/Foxy/
05:51 AM XXCoder: looks like you gonna put it together again first ;)
05:51 AM XXCoder: thats a lathe? interesting
05:51 AM JT-Cave: yea late 1800's spoke lathe
05:51 AM XXCoder: makes spokes for tires ye olde days?
05:51 AM XXCoder: *wheel
05:51 AM JT-Cave: yea wagon wheel spokes
05:52 AM XXCoder: jt man
05:52 AM XXCoder: talking about lathes, finally ran a lathe today
05:52 AM XXCoder: been what 3 years? heh
05:52 AM XXCoder: simply not enough jobs now and we reverted to full time
06:24 AM JT-Cave: at least your back to full time, what kind of lathe did you run
06:25 AM Tom_L: morning
06:25 AM JT-Cave: I can finally take down all the tarps over the tomato plants but can't put them away until it stops raining and I can dry them out
06:25 AM JT-Cave: morning
06:27 AM Tom_L: that's some old iron
06:27 AM JT-Cave: yea and still in production making handles
06:28 AM Tom_L: not gonna get much over 40ish here today
06:29 AM JT-Cave: forecast high of 53°F here today and tonight forecast low 50°F
08:28 AM BitEvil is now known as SpeedEvil
10:27 AM jymmmm: good morning
11:58 AM JT-Shop: hmmm I have a magnetic reed switch that can take 50 mA max and I need to pull in a control relay with a coil rated at 37 mA, I'm concerned that it's too much any ideas?
11:59 AM dirty_d: use a transistor?
11:59 AM SpeedEvil: I would expect that to quickly fail - reed switches are really not meant for inductive loads
11:59 AM JT-Shop: that's what I was thinking
12:00 PM SpeedEvil: The low margin eliminates any simple solutions - large snubber - for example
12:00 PM dirty_d: add a freewheel diode to the relay?
12:01 PM Tom_L: hamlin makes logic level relays
12:01 PM Tom_L: he101 iirc is one
12:02 PM CarpetDiem is now known as PointedSticks
12:04 PM Tom_L: may not be suitable for what you're doing, dunno
12:04 PM JT-Shop: https://www.digikey.com/products/en/relays/reed-relays/964?k=he101
12:08 PM SpeedEvil: dirty_d: that doesn't wholly help, but does somewhat
12:17 PM dirty_d: SpeedEvil, why doesn't it help?
12:18 PM SpeedEvil: I gues if the supply voltage is low.
12:18 PM SpeedEvil: It would.
12:18 PM SpeedEvil: 5V, probably work OK
12:31 PM unterhaus_: Intermediate relay is what I always do
12:36 PM JT-Shop: hmm all the solid state relays I see are AC load
12:43 PM SpeedEvil: optomos may be a useful keyword
12:45 PM JT-Shop: https://www.amazon.com/ELECTRONICS-SALON-Signal-Relay-Module-version/dp/B00M90UUOU
12:46 PM JT-Shop: ok
12:50 PM JT-Shop: https://www.amazon.com/HiLetgo-Channel-OPTO-Isolated-Support-Trigger/dp/B00LW2G7V6/
01:50 PM jdh: AC SSR is cheap and easy.
01:50 PM jdh: DC not so much
02:10 PM PointedSticks is now known as EyesWithoutAFace
02:14 PM skunkworks: https://www.youtube.com/watch?v=uLoavsbtD2k&lc=UgjJSn-dAFVpp3gCoAEC
02:15 PM skunkworks: 'can't share the exact code... - sounds like he is using a spindle synced type motion like G33 *g32 he is saying
02:21 PM Tom_L: crazy
02:24 PM Thorhian: SSR?
02:24 PM Tom_L: JT-Shop, what voltage and current?
02:25 PM Tom_L: https://www.mouser.com/datasheet/2/657/lvd-series-control-relays-1371049.pdf
02:28 PM pcw_home: for 37 mA relay if you want to reduce your reed switch load I would just use a 5 cent transistor
02:29 PM Tom_L: true
02:31 PM EyesWithoutAFace is now known as GiantElectricPen
02:33 PM GiantElectricPen is now known as Space4Rent
03:02 PM Space4Rent is now known as FreeParking
03:15 PM FreeParking is now known as ZeroCrossing
03:33 PM JT-Shop: Tom_L, these are just control relays I need to operate a pneumatic valve or two and be part of the logic
03:35 PM Tom_L: ok
03:35 PM Tom_L: JT-Shop, you have a rpi4?
03:35 PM pcw_home: Somehow I imagined it was part a a chicken coop control system
03:35 PM Tom_L: can you tell me if the even row of IO pins is on the inside or by the board edge?
03:35 PM Tom_L: building a spi cable..
03:36 PM Tom_L: just verifying, the doc show even near the board edge
03:37 PM Tom_L: pcw_home, i'm sure if he has any leftover parts they will end up there
03:46 PM JT-Shop: Tom_L, yes I have one
03:47 PM JT-Shop: pcw_home, automate this late 1800's spoke lathe https://gnipsel.com/images/customers/Foxy/
03:47 PM skunkworks: so... i guess i have been running 1khz...
03:48 PM Tom_L: is pin 1 in the corner or by the ethernet plug?
03:50 PM skunkworks: certainly for as long as i have been doing the poly boring..
03:56 PM pcw_home: I've run my RPI4 with Ethernet for a couple of days at 1 KHz it seems ok if a bit close to the wire servothread-tmax wise
03:59 PM pcw_home: JT-Shop is that for wagon wheels?
04:03 PM ZeroCrossing is now known as CheeseShirt
04:04 PM skunkworks: pcw_home: tmax is in ns?
04:04 PM skunkworks: on rpi?
04:05 PM Deejay: gn8
04:10 PM pcw_home: i get about 800 usec
04:10 PM skunkworks: servo-thread.tmax 458513
04:11 PM pcw_home: Thats great, is that after a long uptime?
04:12 PM pcw_home: yes on the RPI4 tmax is in ns
04:12 PM skunkworks: not too long yet. 30 min so far
04:13 PM pcw_home: yeah I think you need a day or three to be sure...
04:15 PM skunkworks: sure. but it has certainly been up quite a while at 1khz. i switched configs and didnt know it was at 1khz
04:16 PM pcw_home: wow our new sheep are bold, they climbed up our back porch stairs and ate some orchid leaves
04:18 PM pcw_home: sneaky little devils
04:27 PM jymmmm: pcw_home: poisonious?
04:27 PM jymmmm: poor orchids
04:28 PM pcw_home: no but we moved them out of reach
04:28 PM jymmmm: Has anyone messed around with jump packs as power banks?
04:28 PM jymmmm: pcw_home: oh good, there's always electric fence =)
04:32 PM CheeseShirt is now known as CaptHindsight
04:34 PM jymmmm: CaptHindsight: !!!
04:39 PM jymmmm: Basically I'm wondering if you can use a 20AH jump box as a power bank to run a ~250W inverter for 6 to 8 hours
04:39 PM pcw_home: I'm afraid I would be the one getting shocked if we had an electric fence
04:39 PM jymmmm: pcw_home: haha, you're probably right, and they'll NEVER ever even come close to it
04:40 PM jymmmm: it's hailing
04:45 PM Tom_L: well hail!
04:51 PM jymmmm: lol
04:57 PM Tom_L: jymmmm, how big?
05:04 PM jymmmm: Tom_L: tiny, stopped hailing now
05:25 PM pcw_mesa: andypugh: at one time you told me how to see a full precision float hal pin value
05:25 PM pcw_mesa: (most of the hal utilities truncate the doubles for display)
05:25 PM pcw_mesa: do you remember how this was done?
05:25 PM andypugh: I’m afraid not.
05:25 PM andypugh: Are you sire it was me?
05:26 PM pcw_mesa: yes
05:26 PM pcw_mesa: well maybe not since I cant remember how it was done
05:28 PM andypugh: I can imagine that it would be fairly easy to change the printf format in halcmd show
05:28 PM andypugh: But that would mean recompiling.
05:29 PM pcw_mesa: this was when I was testing the BISS interface (halcmd/halshow/halmeter seem to only show 7 or so significant figures, this fails to show individual counts pretty quickly with 20 bit absolute encoders )
05:30 PM pcw_mesa: I thought it was simpler, (like some other utility)
05:41 PM rmu|w: pcw_mesa: it should be possible from tcl
05:44 PM rmu|w: something like puts [format "fmtstring" [hal gets "my.signal.name"]]
05:46 PM pcw_mesa: Thanks, I'll give that a try
06:24 PM ve7it: i:
06:24 PM ve7it: dir
06:24 PM ve7it: dam
06:41 PM skunkworks: pcw_mesa: 3 hours 480216 ns
06:46 PM Tom_L: ain't too pretty but i got a 26 -> 40 pin spi adapter
06:49 PM skunkworks: Tom_L: do you have everything to test,?
06:49 PM Tom_L: no pi board yet
06:49 PM Tom_L: just gettin stuff ready
06:49 PM Tom_L: should be here by the weekend i hope
06:50 PM skunkworks: nice!
06:50 PM Tom_L: i could go ahead and make the image sd
06:50 PM Tom_L: i got a 64Gb mini card
06:51 PM Tom_L: any reason to back up what's on it to an img file?
06:54 PM Tom_L: i think they said the sd comes with NOOBS on it. dunno what that is. i assume most use Raspbian
06:55 PM Tom_L: oh, it's just an installer for Noobs
07:09 PM MacGalempsy: noobs is like the basic setup. Raspbian lite does not have a GUI
07:10 PM Tom_L: pcw_mesa, if spi gets more popular for the rpi, a suggestion would be to make a 40 pin to 26 pin adapter board to plug both the Pi4 and 7i90 together since it's an awkward pinout
07:10 PM pcw_mesa: yeah or use a 7C81
07:10 PM Tom_L: it could be nice n short and shielded too
07:11 PM Tom_L: or that
07:12 PM pcw_mesa: a tiny circuit card with 40 an 26 pin connectors for flat cables would be easy enough
07:13 PM pcw_mesa: could also AC bypass the 5V and 3.3V signals for more effective grounds
07:14 PM pcw_mesa: I'll give it some thought
07:15 PM pcw_mesa: you could also make a similar adapter for one of the really cheap Alibaba FPGA boards
07:17 PM pcw_mesa: skunkworks: what is your read-timeout set for?
07:30 PM Tom_L: pcw_mesa, the 7i80 zip has no fallback file
07:33 PM pcw_mesa: in the fallback directory?
07:34 PM Tom_L: yes
07:34 PM Tom_L: the directory is there but no file
07:34 PM pcw_mesa: At least some are in the main directory
07:34 PM Tom_L: i just pulled the zips again in case anything was updted
07:35 PM Tom_L: yeah i see one in the main hostmot2 folder
07:35 PM pcw_mesa: ill move or copy those to the fallback directory
07:35 PM Tom_L: i see at least 4 there now
07:36 PM pcw_mesa: most of those are ancient as well and need to be rebuilt
07:37 PM pcw_mesa: ill have to see what I need to do to get my batch file that makes those updated
07:37 PM Tom_L: probably not too many need those anyway
07:37 PM pcw_mesa: lots of source changes since I built those
07:38 PM Tom_L: :/ that's why i just grabbed em... in hopes they were the latest n greatest!
07:38 PM pcw_mesa: had to spilt out hostmot2 and newerhostmot2 (sp6 and >)
07:39 PM pcw_mesa: some newer code uses SRL32s and those are SP6 and greater only
07:40 PM Tom_L: i want the seveni90spi.xise right?
07:40 PM pcw_mesa: yeah
07:41 PM pcw_mesa: I _think_ I added the latest modules to all the project files
07:42 PM pcw_mesa: but you may find a project that missing rcpwmgen.vhd and rcpwmrate.vhd
07:42 PM CaptHindsight: pcw_mesa: does it look like the https://cnc32.ru/orangecnc/ will fit into the 7C81?
07:43 PM pcw_mesa: probably if it has a RPI compatible 40 pin GPIO header
07:43 PM CaptHindsight: it is supposed to be
07:43 PM CaptHindsight: 40 Pins Header,compatible with Raspberry Pi B+
07:45 PM CaptHindsight: I wish they had a version with 2GB
07:45 PM CaptHindsight: of RAM
07:45 PM skunkworks: pcw_mesa: sorry - have to look when I get back there
07:45 PM pcw_mesa: Not sure how well the generic hm2_spi driver will work (its not as good as the hardwired hm2_rpspi driver on the PI)
07:47 PM pcw_mesa: Yeah 1G of RAM is going to be a bit painful if you have complex backplots
07:47 PM pcw_mesa: I wonder if the OrangePI has the same issues with VTK as the RPI
07:48 PM pcw_mesa: (openGL issues AFAIU)
07:49 PM CaptHindsight: has 2GB ddr http://www.orangepi.org/OrangePiPrime/
07:49 PM CaptHindsight: also this model http://www.orangepi.org/orangepiplus2/
07:50 PM CaptHindsight: pcw_mesa: do you know what the openGL issues are?
07:50 PM pcw_mesa: CaptHindsight: I forget, did I tell you the xy2mod works now (in master) but needs the latest firmware
07:50 PM CaptHindsight: there are open drivers now for the mali GPU
07:50 PM CaptHindsight: pcw_mesa: yes you did
07:50 PM CaptHindsight: thank you
07:50 PM pcw_mesa: Pretty sure RMU knows
07:52 PM pcw_mesa: xy2mod has only been tested on a cheap galvo (no status, command, or 18 bit mode) so fancy stuff is not tested
07:57 PM pcw_mesa: Lovely thing about the Chinese xy2-100 Galvos is that they have zero protocol documentation
07:58 PM CaptHindsight: Golook
07:58 PM CaptHindsight: GoLuk
08:02 PM CaptHindsight: somebody there gets a design, copied from customer or gets a hold of a working board..
08:02 PM CaptHindsight: it gets copied
08:03 PM CaptHindsight: after 2-3 layers of copies there is nobody that even knows the specs anymore
08:03 PM CaptHindsight: they just have a pcb layout and a BOM
08:05 PM CaptHindsight: i could give them a working XY2-100 controller/amp and they would copy it if they can make a buck
08:08 PM pcw_mesa: I had to rummage through controller manuals to figure some things outs
08:08 PM CaptHindsight: https://sci-hub.tw/10.1109/ISOCC.2017.8368782
08:09 PM CaptHindsight: Implementation of the XY2-100 protocol on low-cost microcontroller
08:11 PM pcw_mesa: Yeah I think I saw that. One issue is that the cheap galvos dont implement interpolation so the controller has to
08:11 PM CaptHindsight: pcw_mesa: http://www.newson.be/doc.php?id=XY2-100 many just use this section of the spec http://www.newson.be/doc.php?id=XY2-100
08:12 PM pcw_mesa: Yes I started with that
08:12 PM CaptHindsight: https://dvd.ilphotonics.com/Ray-Motion%20-%20galvanometers%20-%201D-2D-3D%20scanners/Motion%20Control%20-%20Optomechanics/Interface%20XY2-100.pdf
08:13 PM pcw_mesa: the galvo I have has not status return and ignores the control bits
08:14 PM pcw_mesa: without interpolation you get ringing every step
08:14 PM CaptHindsight: yeah, just gimme the position data
08:15 PM pcw_mesa: so it works much better when treated like a stepgen with velocity control
08:15 PM CaptHindsight: does it ring at lower speeds and shorter moves?
08:15 PM pcw_mesa: (so it interpolates between LinuxCNC waypoints)
08:15 PM CaptHindsight: or just rings not matter what without interpolation?
08:15 PM pcw_mesa: Yes
08:16 PM CaptHindsight: sounds like the amp is not tuned
08:16 PM jymmmm: ve7it: Yo, check it out.... DIY solar generator https://www.youtube.com/watch?v=Nf9X4YIK9xA
08:16 PM CaptHindsight: and you were running the galvo at full current?
08:17 PM pcw_mesa: In any case you dont want to just send positions sine you have no control of velocity
08:18 PM pcw_mesa: (between waypoints)
08:18 PM jymmmm: pcw_mesa: (what if I have a bungy cord?)
08:19 PM pcw_mesa: that might help
08:19 PM jymmmm: ok, good to know ;)
08:19 PM pcw_mesa: CaptHindsight: as far as I know full current
08:20 PM unterhaus: "there aren't any segmentation faults like in a proper programming language"
08:21 PM pcw_mesa: the xy2mod interpolator also supports accel so theoretically you could have a reversal between waypoints
08:21 PM jymmmm: paperback $11.61, Kindel $12.99, WTF?!
08:22 PM Tom_L: get both
08:22 PM jymmmm: Tom_L: more like neither (maybe)
08:23 PM CaptHindsight: pcw_mesa: do you recall the + and -15V current requirement?
08:25 PM pcw_mesa: I didnt pay too much attention since for $166 you get the +-15V supply but maybe 2-3 Amps?
08:25 PM CaptHindsight: ok, sounds right
08:28 PM CaptHindsight: rms is ~3A for mirrors that size, peak may be 10A
08:30 PM jymmmm: Ok, almost ALL of you need to get this tshirt... https://chummytees.com/products/funny-beard-growth-chart-amish-professor-wizard-god-beard-t-shirt-hoodie-tank-top
08:31 PM JavaBean: damn, i am off that chart
08:31 PM CaptHindsight: jymmmm: I just went back to the Einstein moustache
08:31 PM jymmmm: CaptHindsight: heh
08:32 PM CaptHindsight: i get too much stuff sticking to the beard
08:32 PM jymmmm: LMAO, Got lunch? And Dinner? For 3 days?
08:32 PM jymmmm: CaptHindsight: ^^^^^^^^
08:32 PM pcw_mesa: my wife trims my beard when I start getting the homeless look
08:33 PM JavaBean: why use wife? the flycutter in the mill works just fine
08:33 PM jymmmm: pcw_mesa: you could also stand next to the 510 onramp?
08:33 PM jymmmm: always*
08:34 PM pcw_mesa: wiring is easy with step/dir daughtercards (follow step/dir polarity on differential xy2-100 signals)
08:34 PM veegee: I want to replace all my power tool cords with a single cord that plugs right into the power tool
08:34 PM veegee: like an air tool quick disconnect
08:35 PM veegee: What would be the best type of connector for that? Some kind of mini twist lock
08:35 PM veegee: standard NEMA twist lock receptacles are way too big
08:36 PM SpeedEvil: 1/4" headphone jack.
08:36 PM SpeedEvil: https://iss-sim.spacex.com/ Sort of on topic. It's running linux, and it's CNC
08:37 PM veegee: Something like an IEC C7 would be appropriate if it had a locking mechanism
08:37 PM SpeedEvil: 'all' my powertools - that's a bit wimpy currentwise
08:38 PM CaptHindsight: veegee: FCI made one years ago that lubricated the pins one every insertion and removal and had a thrum press to open and close, no rotation
08:38 PM jymmmm: JT-Shop: https://www.amazon.com/dp/B07FXH5ZZK/
08:38 PM CaptHindsight: thumb press
08:39 PM SpeedEvil: C13 would be about right, but it's a bit big
08:41 PM veegee: Yeah, just needs to support 120V 15A
08:41 PM veegee: I have like 4 angle grinders on my bench because I don't like swapping discs. But I hate that there's 4 cords
08:42 PM veegee: Would be nice to be able to just swap the cord from one tool to the other just like an air tool
08:42 PM jymmmm: ve7it: Total build cost (no solar panels) $650
08:43 PM elmo40_: veegee: there is 125V 15A twist locks. Pricey little bitches, though.
08:43 PM jymmmm: SpeedEvil: lmao
08:43 PM veegee: elmo40_ those are too big
08:44 PM SpeedEvil: Grounded?
08:44 PM CaptHindsight: having to twist is a pain
08:44 PM veegee: NEMA L5-15 is huge
08:45 PM SpeedEvil: https://en.wikipedia.org/wiki/IEC_60309#/media/File:CEE_16A_230V_Wandsteckdose_Pinning.png would be great
08:45 PM roycroft: l6 is for 250vac
08:45 PM roycroft: you would want l5-15
08:45 PM roycroft: for 125vac
08:45 PM SpeedEvil: But it is 'slightly' too large
08:45 PM Rab: veegee, https://www.alibaba.com/product-detail/4-pin-gold-plated-bayonet-lock_1354734870.html
08:45 PM roycroft: and i may have a bunch of l5-15 plugs that are going on ebay soon
08:46 PM SpeedEvil: Rab: that's as big as a C13
08:46 PM Rab: 34mm OD, still pretty beefy.
08:47 PM Rab: veegee, https://en.wikipedia.org/wiki/Speakon_connector
08:48 PM jymmmm: veegee: https://www.amazon.com/gp/product/B00OVAXMZU/
08:49 PM Rab: In fact I'm thinking of PowerCon, the Speakon variant for AC power: https://en.wikipedia.org/wiki/PowerCon
08:49 PM jymmmm: veegee: https://www.amazon.com/gp/product/B002EDM9AU/
08:49 PM CaptHindsight: yeah something like a XLR cable to cable connector
08:50 PM CaptHindsight: no twisting
08:50 PM CaptHindsight: I don't see the FCI connectors anymore
08:50 PM jymmmm: 250V@20A to the links I gave above
08:52 PM CaptHindsight: https://www.neutrik.com/en/product/nac3fcb
08:52 PM CaptHindsight: https://www.neutrik.com/en/product/nac3fca
08:52 PM Rab: I think I'd rather have an inline connector on a cable pigtail, using the original strain relief, then try to hack up each tool to safely mount a panel-mount connector.
08:54 PM SpeedEvil: https://docs.rs-online.com/5cb2/0900766b813829f2.pdf
08:57 PM Rab: Neutrik is the seal of quality in this space. It might be wise to buy through a real AV distributor rather than Amazon. https://audio-video-supply.markertek.com/search?lbc=markertek&method=and&p=Q&sitepref=1&ts=custom&uid=349502511&w=powercon&af=cat2%3aconnectorsadapters_powerconnectorswireconnectors%20cat1%3aconnectorsadapters
08:57 PM Rab: https://www.parts-express.com/Search.aspx?keyword=powerCON&sitesearch=true
08:58 PM Rab: Looks like Amazon isn't any cheaper, anyway.
08:58 PM CaptHindsight: I'm sure somebody in China can copy it for you :)
08:58 PM SpeedEvil: I've been tempted to do the same with C14s
08:58 PM SpeedEvil: 3
08:58 PM SpeedEvil: They are not _that_ bulky.
08:59 PM jymmmm: This is a sexy switch... https://www.amazon.com/Support-Symbol-Button-Toggle-Switch/dp/B00ZR7MMXO/
08:59 PM CaptHindsight: https://www.alibaba.com/countrysearch/CN/neutrik.html
09:00 PM CaptHindsight: 50 cents ea
09:01 PM SpeedEvil: 1 cent per op
09:03 PM veegee: jymmmm those look good
09:03 PM veegee: XLR type looks good actually
09:04 PM jymmmm: veegee: and they are rated at 250V@20A
09:04 PM Tom_L: replace all your house switches with em
09:04 PM jymmmm: veegee: NOTE: blue and wwwwwhite ARE keyed differently
09:05 PM veegee: NEMA 5-15 (regular 120V wall straight blade) is the worst
09:05 PM veegee: how in the hell did it become standard
09:05 PM jymmmm: Tom_L: I wish!
09:06 PM veegee: XLR connectors also have a nice "snap" to them as they lock into place
09:07 PM veegee: I like that
09:07 PM veegee: Also what's the purpose of the hole in NEMA 5-15 plugs blades?
09:07 PM Rab: veegee, if you use XLR, choose a suitably-rated part. Many 3-pin types aren't rated for 125V/15A.
09:07 PM veegee: I thought at least it would be for a mini retaining ball detent, but I've never seen it in practice
09:07 PM veegee: it would at least hold the plug in place with a little force instead of being purely linear friction
09:08 PM Rab: In fact according to Digi-Key, Neutrik's not on the list if you filter for 15A. Just Switchcraft and "IO Audio Technologies".
09:08 PM veegee: Every plug I have has holes in the blades, but I've never seen a receptacle have a detent to make use of it
09:09 PM veegee: Rab those look good too, and pretty cheap
09:09 PM elmo40_: veegee: the 125V twist lock is the same size as a normal plug but round.
09:10 PM veegee: elmo40_ NEMA L5-15?
09:10 PM veegee: The point is, it has to be smaller than that, so I can remove the built in power cable on my drills/angle grinders and just have an inlet
09:11 PM veegee: so can't be like a 3cm diameter thing
09:12 PM veegee: something XLR sized would be great. I have my headphone connector sitting in front of me and it measures 2cm in diameter including the shroud
09:12 PM veegee: That feels like a great size and should easily be able to handle the conductor for 15A
09:13 PM veegee: Just for reference, the outer diameter on my Makita 5" angle grinder's cord strain relief rubber housing is 20mm
09:13 PM veegee: The Makita 7"'s one is 26mm
09:13 PM Thorhian: I'm pretty hyped that my Mesa boards should be here this Friday!
09:15 PM Tom_L: what'd you end up getting?
09:16 PM Choscura: do y'all have dremel sidecutting bits
09:16 PM Choscura: I have recently found these quite win
09:16 PM Thorhian: The 7C81 and 7i76 Tom_L
09:17 PM veegee: Choscura be very careful with the sum-ting-wong brand for cut off wheels
09:17 PM veegee: I had like three of them explode next to my face. I was wearing a full face shield though
09:18 PM veegee: I never go wun-hung-lo brand for tooling.
09:18 PM CaptHindsight: ShoKing Brand connectors?
09:18 PM veegee: Might try those though
09:19 PM Choscura: I mean, I have spent 1/4 of my life in thailand, where 'made in china' is a sign of a specially imported extra-high-quality that is charged extra for, I basically treat all of my tools as if this were the late bronze age. :D
09:19 PM veegee: Hmmm DC barrel jack type, why didn't that come to mind before
09:20 PM Choscura: this sidecutting bit is still so win that WHEN it breaks I will emery off the end and keep using the stub.
09:20 PM Choscura: and I will go buy 4 next time I have the spare $20 at walmart.
09:20 PM Choscura: worth it.
09:21 PM Choscura: ok, probably not 4, but at least a couple of spares.
09:21 PM Choscura: it's a drill bit but it's got the flute cut at a taper so it cuts aggressively out sideways
09:23 PM veegee: Hmm these plugs actually look decent: https://www.aliexpress.com/item/4000980757174.html
09:24 PM veegee: Idiotic .html suffix for a page that's definitely not a static HTML file
09:30 PM dirty_d: those are some nice looking connectors
09:37 PM elmo40_: veegee: what current do you need it to carry?
09:56 PM CaptHindsight: we had FCI make us a power connector with fiber connections
09:57 PM CaptHindsight: it was like the Neutrik but it had a small sponge on the female socks to hold a lubricant
09:58 PM CaptHindsight: so very time to plugged it in or out it would wipe the power pins
09:58 PM CaptHindsight: so every time you ...
09:58 PM CaptHindsight: lasted for years being unplugged a few times per day
10:07 PM flyback: https://www.bgmicro.com/1B1688.aspx

11:23 PM Tom_L: it's not c-grid
11:23 PM Tom_L: i don't think anyway
11:24 PM Tom_L: i can find all sorts of male headers
11:25 PM MovingSucks: 100 mil pin header?
11:25 PM Tom_L: yup
11:25 PM MovingSucks: IDC
11:26 PM Tom_L: right but female with thruhole

11:50 PM veegee: TIG welding copper: https://www.youtube.com/watch?v=3pV6c0TkbEs
11:50 PM veegee: Is he using AC or DC?
11:51 PM veegee: I'm going to weld a copper connector to my ground clamps to be able to easily switch between them with a single cable. I can just solder with 63/37 solder directly to the brass, but I'd rather weld for higher electrical conductivity
11:51 PM veegee: Should I use AC or DC? I've never TIG welded copper/brass
11:53 PM Tom_L: get some hvac silver solder
11:56 PM veegee: Tom_L is it pure silver?
11:56 PM veegee: Stupid question
11:56 PM veegee: of course it isn't
