08:24 AM aandrew: rue_mohr: your test is not accounting for relative differences of loudness perception due to frequency though, I'm not sure how that can be a valid test
08:32 AM aandrew: I don't see how the dozen tones at various amplitudes is a bad test, you run it longer and build up a spectrum very easily
08:32 AM aandrew: Tom_L> i don't think the fpga pin has enough drive for the opto
08:32 AM aandrew: I'd be surprised if it did, unless it's a really old FPGA. Most can't drive more than a few mA at most
08:32 AM aandrew: regarding fast optos, I learned a trick to speed up optos significantly
08:32 AM aandrew: let me dig out hte URL
09:59 AM polprog: afternoon
09:59 AM polprog: i got the fibreoptic transceiver working yesterday night
10:00 AM aandrew: I saw that on twitter
10:00 AM aandrew: that's pretty cool
10:01 AM polprog: :)
10:01 AM polprog: ive got an arduino uno clone, m328p with a 16M clock
10:01 AM polprog: It stopped responding to the USB programmer
10:02 AM polprog: after i flashed some UART-heavy sketch
10:02 AM polprog: it talks to the AVR Dragon over ISP fine tho
10:02 AM polprog: so I dont know what the issue is...
10:02 AM aandrew: weird
10:02 AM aandrew: I thought you should always be able to get back to bootloader unless you replaced it
10:02 AM Tom_L: hi
10:02 AM polprog: it is weird
10:02 AM polprog: Hi Tom
10:03 AM polprog: i tried reflashing other bootloaders.. but it doesnt work
10:03 AM aandrew: are the uart pins damaged?
10:03 AM polprog: still does not want to talk over UART
10:03 AM aandrew: erase and put a bootloader should have completely fixed it
10:03 AM polprog: the pins look OK, i even replaced the usb-uart IC (removed it and used a usb-uart converter)
10:03 AM aandrew: if you flash a GPIO wiggler for the uart pins do they wiggle? or one that reads the rxd pin (as gpio) and echoes its state to the txd pin (as gpio)
10:04 AM polprog: the converter resets it fine with DTR
10:04 AM polprog: hmm, ill try to make a hex file of that
10:11 AM polprog: not now tho..
10:24 AM Tom_L: yay cc has $0.00 now
10:24 AM Tom_L: (won't last long)
10:25 AM polprog: avrdude: verification error, first mismatch at byte 0x0000
10:25 AM polprog: 0xff != 0x3f
10:25 AM polprog: avrdude: verification error; content mismatch
10:25 AM polprog: ok, i think that 328p clone is shot then
10:26 AM polprog: i dont have any 328p at all in stock
10:26 AM polprog: guess this makes it a deaduino
10:27 AM polprog: maybe I can attach a 555 there xD
10:43 AM Tom_L: start using 32u2 and i can hook you up
12:52 PM polprog: ive got 32s in dip i think
12:54 PM polprog: But i need more arduinos anyway
12:54 PM polprog: At least two to test the transceivers
02:02 PM rue_bed: aandrew, the test is relative, its meant to show the frequency dropoff relative to itself, the fact that I used the same signal for everyones test, gives a hint as to the overall sensativity
02:05 PM rue_bed: aandrew, so, ma has a problem with her eustachian tubes on one side, because the other test is discrete, it wasn't detected, her high freq attenuation will actually change depending on how the tube is doing, they didn't catch that, and would have applied a hearing correction not knowing it
02:08 PM rue_bed: polprog, I'v seen the error your having, I usually just ditch the serial programming and use spi
02:09 PM rue_bed: aandrew, tom needs 667Hz, and a small circuit :)
02:09 PM aandrew: rue_bed: sounds like the specialist was either not being thorough or disinterested, sadly
02:09 PM rue_bed: aandrew, they cant catch that with thier tests
02:09 PM rue_bed: they just want to sell here an $8000 hearing aid
02:10 PM rue_bed: but she isn't elligable for the insurance program
02:10 PM rue_bed: the only reason its $8k is BECAUSE of the insurance program
02:11 PM rue_bed: I wish I were better at DSPs
02:12 PM polprog: yeah im using spi for now
02:12 PM rue_bed: iirc IIR filters dont do high pass
02:12 PM rue_bed: polprog, just go with that
02:12 PM polprog: Tho even buspirate with spi does bot want to burn the bootloader. And i need it working with arduino ide to test my boards
02:12 PM rue_bed: I think there is something about the state of the serial hardware that something doesn't init properly
02:12 PM aandrew: rue_bed: yep, that is true, insurance drives the cost up
02:13 PM polprog: I couls write bare metal code but the target audience will likely use arduino ide..
02:13 PM polprog: So i want to use that
02:13 PM rue_bed: what, polprog use avrdude to flash it direct
02:13 PM rue_bed: ah
02:13 PM rue_bed: yes, that problem
02:14 PM rue_bed: ok, survey!!! a two button remote, left and right buttons, one on, one off, which is which?
02:14 PM rue_bed: on at left or right?
02:16 PM rue_bed: I made a remote for the lights in my room, and it always seems to be backwards
02:16 PM aandrew: rue_bed: left = off, right = on
02:16 PM aandrew: I wonder if southpaws would say the ohter way
03:13 PM rue_mohr: huh, thats what I did
03:20 PM rue_mohr: ok shower is out of the way
03:20 PM rue_mohr: I need to have breakfast and go install some woodwork for a guy
03:22 PM Tom_L: .
03:31 PM rue_mohr: -
03:35 PM rue_mohr: well, I was up till 6am last night
03:40 PM rue_mohr: havin breakfast, then I'll have lunch, then woodwork
04:52 PM polprog: i think i have a picture
04:52 PM polprog: i flashed a working bootlaoder with dragon
04:52 PM polprog: then flashed a uart sending program with ide
04:52 PM polprog: then the usb programming stopped working
04:53 PM polprog: re-flash the bootloader, cycle begins again
04:53 PM polprog: now i have a feeling the ide deletes the bootloader, like why the fuck even
04:53 PM polprog: what is this garbage
05:04 PM rue_mohr: shouldn't
05:04 PM rue_mohr: maybe the boot flag is set wrong
05:04 PM rue_mohr: they cant fix it over serial
05:10 PM polprog: im checking that now
05:12 PM rue_mohr: I"m not sure what normal fuse settings are
05:13 PM polprog: hmm it looks like it does not erase the bootloader now
05:13 PM polprog: ok
05:13 PM rue_mohr: did you change the fuses?
05:13 PM polprog: polprog, so usitn goptiboot for atmega 8 witha 16M xtal osc, the fuses are L:FF, H:CC, from https://github.com/Optiboot/optiboot/blob/master/optiboot/boards-1.6.txt. The high fuse controls the clocks
05:13 PM polprog: i did
05:13 PM polprog: now lets see if it craps out when i uplad a uart heavy sketch
05:14 PM rue_mohr: and the boot vector
05:14 PM polprog: yes and the boot vector
05:15 PM rue_mohr: I need to work out what to get done this weekend
05:17 PM polprog: YES
05:17 PM polprog: YES YES YES YES
05:17 PM polprog: sending crap over uart doesnt disable the USB programming now
05:17 PM polprog: super cool
05:17 PM polprog: i fixed that arduino
05:21 PM rue_mohr: :)
05:36 PM Tom_L: who kept you up til 6am?
05:59 PM polprog: allright
05:59 PM polprog: gotta hit the hay
05:59 PM polprog: gn
07:01 PM rue_mohr: me
07:01 PM rue_mohr: ugh, moon was here
07:02 PM Tom_L: for what?
07:02 PM rue_mohr: no idea, he's gone
07:03 PM Tom_L: oh you missed him?
07:03 PM rue_mohr: yes
07:03 PM Tom_L: i'm gonna go out and put the original config back on the mill
07:03 PM Tom_L: it was acting funny after i made some changes
07:03 PM Tom_L: the pendant was doing odd things
07:04 PM Tom_L: the fpga pin won't drive the opto
07:04 PM rue_mohr: no, thats why I added a buffer
07:04 PM Tom_L: i likely have some buffer chip but i'm not gonna go diggin for it
07:05 PM rue_mohr: did I post the pic of the board I'm pondering to build you and if I do you might never use it
07:05 PM Tom_L: oi didn't see it if you did
07:06 PM Tom_L: i would rather figure out one to plug in the 2nd plug and put all the switches as inputs on it as well
07:06 PM Tom_L: that 2nd ribbon is a mess
07:06 PM Tom_L: looks sloppy
07:06 PM Tom_L: well the whole cabinet kinda looks sloppy but it was working
07:07 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1210291.jpg
07:07 PM Tom_L: i hate to mess with it when it's working good
07:07 PM rue_mohr: I can make it an edge-plug-in card, with headers on the end
07:07 PM rue_mohr: I'm just having a gunshy problem
07:07 PM rue_mohr: I dot hings for people to help them solve problems and they want to go antoher way
07:07 PM Tom_L: it's ok, i can figure something out
07:08 PM rue_mohr: it would be a really nice neat little card
07:08 PM rue_mohr: plug right into the socket
07:08 PM Tom_L: yeah i'm a little hesitant to dig into the box much
07:08 PM Tom_L: seems every time i do something acts up
07:08 PM rue_mohr: you dont have to touch the existing wiring tho
07:08 PM Tom_L: i know
07:08 PM rue_mohr: which is part of what I thought would be good about it
07:09 PM rue_mohr: so
07:09 PM Tom_L: yeah, if i did it, i'd want to add the limits to it. right now they're unprotected too
07:09 PM rue_mohr: I ponder the meaning of life a lot
07:09 PM Tom_L: there is that
07:09 PM rue_mohr: and one of the things I'v come to notice, is that I do a lot of projects
07:09 PM rue_mohr: but my projects do not form a lot of my day-to-day life
07:10 PM rue_mohr: so I just came back from visiting a 9x year old fellow who is a projector kinda like us
07:10 PM Tom_L: i don't do alot for myself either
07:10 PM Tom_L: i finally got new glasses today after 8 yrs
07:10 PM rue_mohr: and I noticed that, altho he's been doing projects for 8x? years, there aren't many of them in his day-today life
07:10 PM Tom_L: i couldn't see the pc screen anymore
07:10 PM Tom_L: covid messed with my vision
07:11 PM Tom_L: i'm sure of it
07:11 PM rue_mohr: so I'm looking at my life evaluating my projects
07:11 PM rue_mohr: what should I be working on that will carry with me thru my life
07:11 PM Tom_L: i honestly would rather be helping somebody else
07:11 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1210291.jpg
07:11 PM Tom_L: benefits 2 that way
07:12 PM rue_mohr: ^^ i posted that pic right?
07:12 PM Tom_L: 2x
07:12 PM rue_mohr: k
07:12 PM rue_mohr: like the idea of the little plug in card?
07:12 PM Tom_L: 50 pin?
07:12 PM rue_mohr: 8 pullup opto-isolated channels, and 8 "raw' pins (with a 100R series resistor)
07:12 PM rue_mohr: yes
07:12 PM Tom_L: if it worked it would be nice
07:12 PM rue_mohr: module, just plugs in
07:13 PM rue_mohr: it'd work
07:13 PM rue_mohr: or 8 outputs and 4 raw, not sure
07:13 PM Tom_L: the IO can go either way on the fpga, that's just a sofware thing
07:13 PM rue_mohr: those screw connector headers take up lots of room
07:14 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/New_Mill_IO_Pinout.pdf
07:15 PM rue_mohr: It wouldn't take me long to bang off, then about 2 months via mail
07:15 PM Tom_L: P2 is that i'd like to get it on so all those are protected
07:15 PM rue_mohr: pdfs are a bit of a pain to open
07:15 PM rue_mohr: all theports are the same
07:15 PM Tom_L: there are 6 or 7 io left to use
07:16 PM Tom_L: all except the first one and it has dedicated functions on it programmed in the fpga
07:16 PM Tom_L: i can change those as needed but they're pretty well set now
07:17 PM rue_mohr: well, 8 output, 4 'raw' card? with pullup, opto-isolated outputs?
07:17 PM Tom_L: all of those are inputs except maybe the Estop and i'd have to check it
07:17 PM rue_mohr: but what you need is just a set of outputs for the A axis
07:17 PM rue_mohr: all the rest of it could be left alone if you just had that
07:17 PM Tom_L: i wouldn't care if they were opto isolated, just having the driver there would help
07:18 PM rue_mohr: wouldn't you be opto isolating them anyhow?
07:18 PM Tom_L: one is a relay but i'm pretty sure it has a diode on it
07:18 PM Tom_L: they aren't right now
07:18 PM Tom_L: ideally yes but not a hard requirement
07:18 PM rue_mohr: I thought your motor drivers were all on isoltaed outputs?
07:19 PM Tom_L: they are and would be
07:19 PM rue_mohr: or do the drivers them selfs isolate?
07:19 PM Tom_L: i would move the estop off the first plug
07:19 PM rue_mohr: if you have new outputs, why move anything?
07:19 PM Tom_L: that would free up 2 outputs i can add the stepgen function to
07:19 PM rue_mohr: if you have new outputs, why move anything?
07:19 PM Tom_L: so all that would be on the first daughter card
07:19 PM Tom_L: ^^^
07:19 PM rue_mohr: hmm
07:20 PM Tom_L: i need to move one signal and that would fix it
07:20 PM Tom_L: but if i do anything to the 2nd plug i may as well fix them all
07:20 PM rue_mohr: so then, the ideal card would ahve how many driven outputs and how many raw connections available?
07:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/P2_pinout.jpg
07:23 PM Tom_L: at least 14 inputs
07:23 PM rue_mohr: well yes, but
07:23 PM Tom_L: the open pins at the top could be half and half
07:23 PM rue_mohr: hmm
07:23 PM rue_mohr: but you need more buffered outputs
07:24 PM Tom_L: there are only 7 available
07:24 PM Tom_L: all i need is one for the estop relay
07:24 PM rue_mohr: hmm
07:25 PM rue_mohr: and you need sourcing outputs not sinking?
07:25 PM Tom_L: a couple of those i forgot to label
07:25 PM Tom_L: i can go either way but sourcing seems to be the way i did it so far
07:27 PM Tom_L: if i had a driver chip which i probably do i could put it on a piece of fr4 and just wire it for the estop
07:27 PM Tom_L: glue it down to something
07:28 PM Tom_L: could probably even deadbug a transistor
07:30 PM Tom_L: SN74HC244DW?
07:30 PM Tom_L: supposedly i have some of those
07:31 PM Tom_L: 74hc125?
07:33 PM Tom_L: you got enough going on to use this as a distraction
07:34 PM Tom_L: i just told myself i'd pic cnc over wiring stuff and so i'm reluctant to start digging thru boxes again
07:36 PM Tom_L: 2n3904?
07:36 PM Tom_L: 2n2907?
07:36 PM Tom_L: i probably have 2n2222 somewhere
07:37 PM Tom_L: or whatever those were
07:38 PM Tom_L: gonna go lay down a bit
09:11 PM Tom_L: ok i copied the config from a backup and things are working like they should now
09:12 PM Tom_L: i must have screwed up a line or something when i was editing yesterday
09:12 PM Tom_L: i'm careful to keep several current backups
09:13 PM rue_mohr: router has its iobus lock up, it couldn't access its hard drives either
09:13 PM rue_mohr: Tom_L, 500 series is much easier to wire
09:30 PM Tom_L: that's just what i have
09:30 PM Tom_L: and if i did one i'd just wire up one signal
09:31 PM Tom_L: i'm kinda relieved the config was the problem, not the wiring
09:31 PM Tom_L: i don't like editing out in the shop
09:32 PM rue_mohr: ok, I made it into the attic to confirm the solar entry point isn't leaking
09:32 PM rue_mohr: there is an old sign of water on it
09:38 PM Tom_L: mmm
09:46 PM Tom_L: the config can be confusing sometimes because they have 2 different methods for defining the pin direction
09:47 PM Tom_L: it depends where it comes from
09:59 PM rue_shop3: hmm
10:03 PM Tom_L: https://www.youtube.com/watch?v=QccPG6LfmEs
10:03 PM Tom_L: i didn't watch the whole thing just the beginning
10:11 PM rue_shop3: am I ever glad I'm in canada
10:12 PM rue_shop3: there are a lot of idle cranes in that lot
10:13 PM rue_shop3: 1st world problems
10:13 PM rue_shop3: partly not paying drivers enough
10:13 PM rue_shop3: also sounds like the shipping yards have too many hoops for people to want to deal with them
10:13 PM Tom_L: workers don't want to work because of the pandemic
10:14 PM Tom_L: places here can't hire ppl
10:16 PM Tom_L: what's a jorneyman get up there an hour?
10:17 PM Tom_L: i heard gas prices in California were like $4.30 gal
10:18 PM Tom_L: California $4.481
10:18 PM Tom_L: current
10:25 PM rue_shop3: heh what a mess
10:26 PM Tom_L: i at least should get another stepper driver
10:27 PM Tom_L: i wonder if you can power one with no motor attached
10:27 PM Tom_L: because it's not something i would leave on it all the time
10:48 PM rue_shop3: should be fine
10:58 PM Tom_L: i emailed them to be sure
11:03 PM rue_mohr: ok, I built and tested a hearing booster amp
11:03 PM rue_mohr: copy of the commercial one I got
11:03 PM rue_mohr: works good
11:03 PM Tom_L: :)
11:06 PM rue_mohr: well, I guess I cant just have icecream for supper
11:06 PM rue_mohr: do you think you would use this card if I make it?
11:07 PM rue_mohr: I spent a lot of time making a wooden skylight frame for a guy last sat and I dont think he's going to use it
11:07 PM rue_mohr: this happens a lot
11:08 PM rue_mohr: the audio boosters tone is out
11:09 PM rue_mohr: I'm not sure where I should correct it
11:09 PM Tom_L: i honestly would like one for the middle slot instead of the end. getting to the first one when i need to is bad enough since i have to unplug that loose ribbon
11:09 PM Tom_L: i would sure try it
11:09 PM rue_mohr: you only want a few outputs and all just inputs tho
11:09 PM rue_mohr: yes?
11:09 PM Tom_L: but honestly you have enough going on and i can figure out a way to do it
11:10 PM Tom_L: yes
11:10 PM rue_mohr: so like 4 inputs and the rest direct with maybe like a 100R series resistor
11:10 PM Tom_L: mostly inputs if you look at that jpg
11:10 PM rue_mohr: hmm
11:11 PM Tom_L: the top 6 or so pins are open and i plan to use one for the estop and that's about it
11:11 PM rue_mohr: your dead ones are
11:11 PM Tom_L: i may need some sort of limit switch to home the rotary
11:11 PM Tom_L: there's only one bad pin that i know of
11:11 PM rue_mohr: just 27
11:12 PM rue_mohr: screw lugs or solder pads?
11:13 PM Tom_L: screw lugs are best but i'm not picky
11:13 PM rue_mohr: hmm, maybe rice and ravioli for supper
11:14 PM Tom_L: IO 37 pin P2-27 is the bad one
11:15 PM Tom_L: i'm not sure why i skipped 15 IO 31
11:15 PM Tom_L: maybe i need to search for that one
11:16 PM Tom_L: odd
11:16 PM rue_mohr: it'd be an input, so I could just wrap it in like normal
11:16 PM Tom_L: that's fine
11:16 PM rue_mohr: make P41-47 the outputs
11:17 PM Tom_L: maybe i should move the MPG-scale down to it
11:17 PM Tom_L: no
11:17 PM Tom_L: P2-1 to P2-11 could be
11:17 PM Tom_L: the rest could be inputs
11:18 PM Tom_L: even numbers are GND and there is one +5v but i think it's an odd number on the top end
11:19 PM Tom_L: i'm checking
11:19 PM rue_mohr: k
11:20 PM Tom_L: pin 49 is +5v
11:20 PM Tom_L: even numbers 2 thru 50 and GND
11:21 PM Tom_L: so pin P2-1 starts with IO24 and P2-47 IO 47 is the last one
11:24 PM rue_shop3: I do have a 50!
11:24 PM Tom_L: hang on
11:24 PM Tom_L: where did i post that last .jpg?
11:24 PM rue_shop3: I'm not good at doing that
11:25 PM rue_shop3: not sure
11:25 PM rue_shop3: different computer
11:25 PM Tom_L: i found it
11:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/P2_pinout.jpg
11:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/P2_pinout1.jpg
11:26 PM Tom_L: last one is from the manual
11:26 PM rue_shop3: I know
11:28 PM rue_shop3: oh, hmm thats thin
11:28 PM Tom_L: i'm pretty sure IO33 34 are inputs too
11:28 PM rue_shop3: wonder if I have...
11:28 PM Tom_L: i didn't mark them for some reason
11:28 PM Tom_L: i'm gonna go sleep i think
11:29 PM Tom_L: i bet i have to invert all those inputs too
11:30 PM Tom_L: since they're going straight to the fpga
11:30 PM Tom_L: on a buffer chip they get inverted
11:30 PM Tom_L: software will probably take care of that
11:31 PM rue_shop3: huh, prettymuch out of double row sockets,
11:31 PM rue_shop3: wtf with that
11:32 PM Tom_L: i pretty much used up all my scsi cables on it too
11:32 PM rue_shop3: :)
11:32 PM Tom_L: i used to be able to get those crimp things locally but he's gone now
11:33 PM Tom_L: you live long enough and all your 'goto' places dissappear
11:33 PM Tom_L: it's kindof a lost feeling
11:35 PM Tom_L: IO33 is input
11:35 PM Tom_L: so is IO34
11:36 PM Tom_L: those 2 weren't marked in my pdf
11:36 PM rue_shop3: I just go to china
11:37 PM rue_shop3: usually I keep the stock ahead of the game
11:37 PM rue_shop3: so if I see a drawer running low I just assume there is backstock
11:37 PM rue_shop3: today there isnt :)
11:37 PM rue_shop3: but I have a direction I can use
11:38 PM rue_shop3: do you recall if the inputs to the motor drivers were alerdy isolated?
11:38 PM Tom_L: pretty sure yes
11:39 PM Tom_itx: The STEP, DIRECTION and DISABLE inputs are opto-isolated. All three inputs work with 2.5V, 3.3V or 5V logic drive signals.
11:39 PM Tom_itx: The input drive current is now 2.5mA at 2.5V so almost all logic family (74LS, 74HC, etc.) can be used to drive these inputs.
11:40 PM rue_shop3: hey, you know those low profile screw headers?
11:40 PM Tom_L: not for sure
11:40 PM Tom_L: there are several types
11:41 PM rue_shop3: see if the average scrw terminal from ali is blue or green right now for me would ya?
11:41 PM rue_shop3: the ones about 0.25" high
11:41 PM Tom_L: what spacing?
11:41 PM rue_shop3: 0.2"
11:41 PM rue_shop3: I should have some stacked industrial ones around here tho

11:43 PM Tom_itx: https://www.aliexpress.com/item/1005001656631415.html
11:43 PM Tom_itx: those are 5mm
11:43 PM Tom_itx: maybe too big
11:44 PM Tom_L: i used to have some small ones that were .1" spacing
11:45 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Control4.jpg
11:45 PM rue_shop3: smaller ones
11:45 PM Tom_L: on that perf board there
11:45 PM Tom_L: the opto that drives the relays
11:45 PM rue_shop3: yea your second link
11:45 PM rue_shop3: so are all the ones your seeing blue?
11:45 PM rue_shop3: they switch production
11:45 PM Tom_L: no some are green
11:45 PM rue_shop3: I'm trying to keep my colour selection balanced
11:46 PM rue_shop3: sometimes they only make blue, sometimes only green
11:46 PM rue_shop3: once in a blue moon you can get grey, red, black
11:46 PM Tom_itx: https://www.aliexpress.com/item/32988997761.html
11:46 PM Tom_itx: 5mm
11:46 PM rue_shop3: so I'm never sure which ones I can replace
11:46 PM rue_shop3: oh maybe it is 5mm
11:46 PM rue_shop3: no, 0.2"
11:47 PM rue_shop3: or 0.2" is 5.08?
11:47 PM Tom_L: i think so yes
11:48 PM rue_shop3: so, total you need more than 12 signals, right?
11:49 PM Tom_L: probably yes
11:50 PM Tom_L: i count 17 inputs on that page
11:50 PM Tom_L: and i may need 2 more inputs for limit switches for A
11:50 PM Tom_L: or home switch at least
11:52 PM rue_mohr: k
11:52 PM Tom_L: no, i've included those as part of the inputs already
11:52 PM Tom_L: IO40 & 41
11:53 PM rue_mohr: dont have the image up, is the socket key for your ports towards the fan or away from it
11:53 PM Tom_L: P2-33 P2-35
11:53 PM rue_mohr: even pins are grounded
11:53 PM Tom_L: best away from it
11:53 PM Tom_L: yes
11:53 PM rue_mohr: there is a _______---__________ in the socket eh?
11:54 PM Tom_L: i'd have to go out and look
11:54 PM rue_mohr: its in one of your images
11:54 PM Tom_L: it's just like the ethernet version and i have it sitting right here
11:54 PM Tom_L: the cutout is away from the fan
11:54 PM Tom_L: i think
11:54 PM Tom_L: lemme go look
11:57 PM rue_shop3: :/ I dont have any thin double sided clad...
11:57 PM rue_shop3: guess I'm stuck with this peice
11:57 PM Tom_L: the tab is away from the fan and the screw terminals should be away from it too
11:59 PM rue_shop3: drat, that puts the headers on the fan side of the pcb
