#garfield Calendar

12:29 AM rue_mohr: oh dear, how old are they in #electronics anyhow, 12?
01:03 AM polprog: dalnet electronics is a weird bunch o_o
01:10 AM rue_mohr: yes
01:10 AM rue_mohr: kinda quiet
02:12 AM rue_mohr: http://www.b-kainka.de/bastel59.htm
02:43 PM rue_shop5: aandrew, jameco to canada, do you know if shipping works?
02:44 PM rue_shop5: (or $50 at border)
02:45 PM Tom_L: you should rent a cabin on this side just for shipping
03:33 PM rue_mohr: heh
03:33 PM rue_mohr: I need to get a passport!
03:42 PM rue_mohr: https://andykong.org/blog/traxionreproduction/
04:07 PM Tom_L: ahh still persuing that
04:10 PM rue_mohr: I finshed it but it didn't work out, not quite sure what I did wrong, but then I dropped it and it all broke, so I'll pick that one up later
04:34 PM Tom_L: :/
04:43 PM rue_mohr: meh
04:43 PM rue_mohr: I want to see if I can get an esp8266 to send network messages to my event server
04:43 PM rue_mohr: then I can get the driveway alerts
04:44 PM rue_mohr: then I can also motivate to build up a new power supply for the pillar lights
04:44 PM rue_mohr: as the current one kinda melted itself
04:44 PM rue_mohr: :) but its still working!
04:44 PM rue_mohr: (for now)
05:47 PM polprog: german test tomorow
05:47 PM polprog: im poking around that wyse bios
06:11 PM rue_mohr: for what?
06:14 PM polprog: just for fun
06:15 PM polprog: im trying to see if i can extract the OS and boot it on something else
06:23 PM rue_mohr: ...
06:23 PM rue_mohr: I thought they booted a normal computer filesystem
06:23 PM rue_mohr: windows or linux or whatever
06:31 PM rue_mohr: http://www.b-kainka.de/bastel59.htm
06:31 PM rue_mohr: http://www.dicks-website.eu/fetosc/enindex.htm <-- dont know if I have a jfet to try that one
06:48 PM polprog: they boot an internal RDP client OS if they cant find a boot disk
06:49 PM polprog: quite weird oscillator
06:49 PM polprog: i have a fet
06:49 PM polprog: a jfet*
06:49 PM polprog: allright
06:49 PM polprog: late... gotta sleep
06:49 PM polprog: gn o7
06:57 PM rue_mohr: ok, that led flasher, then the esp8266, then the fet osc?
06:58 PM rue_mohr: so many things to do!
06:58 PM Tom_L: what was that led flasher about?
06:58 PM Tom_L: cap discharge flasher or something?
06:59 PM rue_mohr: it uses the cap to double up the votlage to the led
06:59 PM rue_mohr: it was pointed out an LM3909 did the same thing
06:59 PM Tom_L: i didn't read it
07:09 PM rue_shop5: oh and fix the juke box
07:09 PM rue_shop5: 2 npn and a pnp
07:26 PM rue_shop5: http://www.b-kainka.de/bast592.jpg
07:30 PM rue_mohr: it works
07:57 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1401698020098404354 video fro tom
07:58 PM rue_mohr: "then the esp8266"
07:58 PM rue_mohr: and I'd like some soup
08:00 PM Tom_L: cute
08:02 PM Tom_L: one of the few circuits that might actually work ok on a breadboard...
08:07 PM rue_mohr: hah
08:07 PM rue_mohr: someone took an RF analyzer to a breadboard and it did a hell of a lot better than I'd have expected!
08:49 PM rue_shop5: hello from ESP8266
08:49 PM rue_shop5: YES!!!
08:49 PM rue_shop5: it can send messages to my event server!!!!
08:49 PM rue_shop5: the driveway project is almost finished!
08:50 PM Tom_L: hah
08:50 PM rue_shop5: and I'll be able to also log the hours on the sewer pump!
08:54 PM rue_shop5: need to write some code to monitor 2 inputs and issue events
08:55 PM rue_shop5: oo I'm all excited, now I know why I bought these
08:56 PM rue_shop5: The conduit for the signals from the pillars comes up in a box beside the shop
08:56 PM rue_shop5: no easy way to get a wire path to anywhere I can do anything with the signals
08:57 PM rue_shop5: so, for now atleast, I'll stick an esp8266 in there, its a stones-throw from the AP
08:59 PM Tom_L: was that what z was messin with when he dissappeared?
09:05 PM rue_mohr: maybe, there are a few thing like this
09:05 PM rue_mohr: their all arduino'd up, I just had to edit the example
09:15 PM rue_mohr: pinMode(pin, INPUT); // set pin to input
09:15 PM rue_mohr: digitalWrite(pin, HIGH); // turn on pullup resistors
09:15 PM rue_mohr: val = digitalRead(inPin);
09:16 PM rue_mohr: see if I can learn to speak arduino
09:16 PM rue_mohr: HIGH or LOW.
09:16 PM rue_mohr: ""
09:19 PM rue_shop5: https://randomnerdtutorials.com/esp8266-nodemcu-digital-inputs-outputs-arduino/
09:19 PM rue_shop5: oh look, magic name mapping
09:20 PM rue_shop5: so I wonder what D0 is called
09:22 PM rue_shop5: https://i2.wp.com/randomnerdtutorials.com/wp-content/uploads/2019/05/ESP8266-NodeMCU-kit-12-E-pinout-gpio-pin.png?quality=100&strip=all&ssl=1
09:22 PM rue_shop5: magic map
09:23 PM rue_shop5: I love the layers of random obscurity that a person could never guess
09:26 PM Tom_L: popularity wins again
09:27 PM rue_shop5: ?
09:27 PM Tom_L: arduino popularity
09:27 PM rue_shop5: at this point its become a freaking standard
09:28 PM rue_shop5: and its standardness is causeing 2nd level standards to be created around it
09:28 PM rue_shop5: but it has me thinking about how to organize my libraries
09:29 PM rue_shop5: its important to seperate out the hardware layers from the software ones
09:29 PM rue_shop5: then you can move your software layers around a lot
09:29 PM rue_shop5: which, I dont like to microcontroller hop, and I do much less than many others, but I still end up on a lot of platforms
09:31 PM Tom_L: i got a bunch of U2 chips that are gonna go to waste
09:31 PM rue_shop5: how many is a bunch?
09:32 PM rue_shop5: not exactly
09:33 PM rue_shop5: like 5? 10? 100?
09:33 PM Tom_L: one sec
09:33 PM rue_shop5: hah
09:33 PM rue_shop5: gets an exact value :)
09:38 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/chips.jpg
09:38 PM Tom_L: i damn near spilled em
09:38 PM rue_shop5: oof
09:38 PM rue_shop5: you know, you MIGHT get a lot on ebay
09:38 PM Tom_L: told you i had a few
09:38 PM rue_shop5: I mean I'd like 'em but
09:38 PM Tom_L: i'm not messin with it
09:39 PM Tom_L: trash man comes once a week...
09:39 PM rue_shop5: people are having issues getting any silicon right now
09:39 PM Tom_L: yeah i got the very last of those back then too
09:39 PM rue_shop5: 154 I think
09:39 PM Tom_L: i had 2x that many
09:39 PM Tom_L: at least
09:39 PM rue_shop5: yup
09:40 PM rue_shop5: good controllers
09:40 PM Tom_L: but they're all paid for
09:40 PM Tom_L: got a few boards left too
09:40 PM Tom_L: dunno how many.. not gonna count those
09:41 PM Tom_L: probably have a handfull of U4 somewhere
09:41 PM rue_shop5: I need to make more projects
09:42 PM Tom_L: my projects need to be metal
09:42 PM Tom_L: or wood but that messes things up
09:43 PM rue_shop5: carefull of wood shavings building up
09:43 PM rue_shop5: history seems to say that woodshops burn down lots
09:43 PM rue_shop5: I have to go clean up around my saws soon
09:43 PM Tom_L: got the part in today for the dryer
09:44 PM Tom_L: kinda glad i had to fix it because it was loaded with lint
09:44 PM rue_shop5: bearing?
09:44 PM Tom_L: just a pulley
09:44 PM Tom_L: bushing
09:44 PM Tom_L: i oiled it but that didn't last
09:44 PM rue_shop5: 'GPIO16' was not declared in this scope
09:44 PM rue_shop5: fun
09:44 PM Tom_L: it had probably burnished the bushing already
09:45 PM rue_shop5: :/ I never did a project thing like you guys did
09:45 PM rue_shop5: makin and sellin stuff
09:45 PM Tom_L: who guys?
09:45 PM rue_shop5: the sprayrers...
09:45 PM rue_shop5: hmm
09:45 PM Tom_L: that's a good one
09:45 PM rue_shop5: there were a few others making and selling baords
09:46 PM Tom_L: i kinda just fell into that
09:46 PM rue_shop5: that was right as arduino started
09:46 PM Tom_L: he was still working on his usb lib and needed something to test the protocol on
09:47 PM Tom_L: so i got the saleae, finished a rev of the board and troubleshooted it on irc i think
09:47 PM Tom_L: i'd run the probe on the signal and he'd fix the lib some more until we got it
09:47 PM rue_shop5: wonder what he's up to now
09:48 PM rue_shop5: that really took off for him
09:48 PM Tom_L: then rif had his data logger i never finished
09:48 PM Tom_L: he went to intern in norway for a bit but i think he's back in Au
09:48 PM Tom_L: got married iirc
09:48 PM Tom_L: iirc working for that led light company... i forget
09:49 PM Tom_L: he interned at atmel
09:49 PM Tom_L: https://www.fourwalledcubicle.com/
09:51 PM rue_shop5: yea
09:51 PM rue_shop5: then they closed that part up and I lost track
09:52 PM Tom_L: creed
09:52 PM Tom_L: i think that was it
09:52 PM Tom_L: led bulbs
09:52 PM rue_shop5: I cant find a list of the pin names for arduino, - esp8266
09:53 PM rue_shop5: maybe its the board spec...
09:54 PM Tom_L: https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/
09:54 PM rue_shop5: ok I think I do have a 12E then
09:54 PM rue_shop5: lets see...
09:54 PM Tom_L: looks that way from the pic you posted
09:55 PM rue_shop5: GPIO16 isn't declared
09:55 PM rue_shop5: so I got something wrong
09:55 PM Tom_L: WAKE
09:55 PM Tom_L: maybe they don't want you using it
09:55 PM rue_shop5: no, caue I just tried GPIO4 and it also said NO
09:55 PM rue_shop5: I cant find a full example of anyone using gpio on a esp8266
09:57 PM Tom_L: does adafruit have xamples?
09:57 PM rue_shop5: not of io
09:57 PM Tom_L: you know jepler works there i think
09:57 PM Tom_L: not positive but pretty sure
09:58 PM Tom_L: he's pretty low key on irc
09:58 PM rue_shop5: I just dont know where they are defined
09:58 PM Tom_L: a major developer of lcnc though
10:00 PM rue_shop5: heh #arduino and ##arduino have been shut down
10:01 PM rue_shop5: oh
10:01 PM Tom_L: pins_arduino.h
10:01 PM rue_shop5: maybe just 16
10:01 PM Tom_L: one for each variant
10:03 PM rue_shop5: it doesn't seem to be there for hte 8266 tho
10:03 PM rue_shop5: it looks like just numbers are working
10:03 PM rue_shop5: I can take a gamble here
10:04 PM rue_shop5: well, it compiled
10:04 PM rue_shop5: ....
10:04 PM Tom_L: https://techtutorialsx.com/2017/04/02/esp8266-nodemcu-pin-mappings/
10:05 PM Tom_L: LED_BUILTIN = GPIO16 (auxiliary constant for the board LED, not a board pin);
10:05 PM Tom_L: that's why
10:05 PM rue_shop5: "d0"
10:05 PM rue_shop5: hah, begginers stuff right?
10:06 PM Tom_L: no, i'm pretty damn good at google :)
10:06 PM rue_shop5: I mean arduino
10:06 PM Tom_L: i know what you meant
10:06 PM rue_shop5: heh
10:06 PM rue_shop5: it says setic pump off...
10:06 PM rue_shop5: where is a wire
10:08 PM rue_shop5: hah
10:08 PM rue_shop5: I must have goofed my code, but just plain numbers worked...
10:08 PM Tom_L: yay
10:09 PM rue_shop5: how did I goof this up...
10:10 PM rue_shop5: https://paste.debian.net/1200232/
10:10 PM rue_shop5: it should see changes in state
10:11 PM rue_shop5: I dont see crossed over variables
10:12 PM rue_shop5: oh the pullup isn't working
10:12 PM rue_shop5: ok
10:13 PM rue_shop5: I can live with hat
10:13 PM Tom_L: internals never worked very well
10:14 PM Tom_L: i wish i could find (cheaper) a .125 cutter like for a T slot
10:15 PM Tom_itx: https://5.imimg.com/data5/ES/EC/MY-4513139/solid-carbide-t-slot-cutter-500x500.jpg
10:16 PM Tom_L: like that
10:16 PM Tom_L: for A12
10:16 PM Tom_L: then i could make it like A3 with no need for that funny fixture
10:17 PM rue_shop5: I have some, but their huge
10:18 PM rue_shop5: too small to make an insert cutter
10:18 PM Tom_L: they're damn'd expensive too and i dunno why
10:18 PM Tom_L: probably because they have to cut the shank alot smaller than the cutter
10:18 PM rue_shop5: this is great tom, this is the event pusher I'v needed for 2 years now
10:19 PM rue_shop5: when I see soemthing stupid expensive, I presume its a dummy-fee, and that if you know what your doing, you dont need the thing, there is a simple way around it
10:21 PM Tom_L: also called woodruff keyseat cutter
10:23 PM Tom_L: found one for $25
10:23 PM Tom_itx: https://www.maritool.com/Cutting-Tools-Keyseat-/-Milling-Cutters-Keyseat-Cutters-Straight-Tooth-Cobalt/c78_231_232_233/p2329/Woodruff-Keyseat-Cutter-1/2-X-.125-Thick-%23-404/product_info.html
10:24 PM Tom_L: i should measure how deep that slot is i suppose
10:24 PM rue_mohr: I dont have a number easily available
10:27 PM Tom_L: i'm just diggin around till bedtime anyway
10:27 PM Tom_L: i doubt i go that route
10:29 PM rue_mohr: ok, where is that todo list
10:30 PM Tom_L: i put mine on the shelf
10:30 PM Tom_L: it's got some dust on it too
10:30 PM rue_mohr: rue_mohr> ok, that led flasher, then the esp8266, then the fet osc?
10:30 PM rue_mohr: http://www.dicks-website.eu/fetosc/enindex.htm <-- dont know if I have a jfet to try that one
10:30 PM rue_mohr: its hard to keep the energy eh?
10:31 PM Tom_L: i'll be up at 4
10:31 PM Tom_L: i worked on the dryer today
10:31 PM rue_mohr: not me!
10:31 PM Tom_L: that's about it
10:32 PM rue_mohr: its great to have your help on stuff like this
10:32 PM Tom_L: you could google just as easy as me
10:32 PM rue_mohr: the links I found didn't have the magic to it tho
10:33 PM rue_mohr: this week I'll try to get the optic beam into the new pillars, and put a detector on the sewer pump
10:33 PM Tom_L: ok, dogs need to go out then it's lights out for me
10:33 PM rue_mohr: I'd like to know how hard its working
10:33 PM rue_mohr: I also need to test the high level alarm
10:34 PM rue_mohr: I was going to do it today but its been pouring rain, so screw that
10:34 PM Tom_L: it was nice today
10:34 PM rue_mohr: warm?
10:34 PM rue_mohr: cool?
10:34 PM Tom_L: mild
10:34 PM Tom_L: 75f and clear right now
10:35 PM rue_mohr: I turned the furnace off a few days ago
10:35 PM Tom_L: 81 tomorrow
10:35 PM rue_mohr: I wonder if I should get an electronic ignightor for it
10:35 PM Tom_L: probably rain too
10:35 PM Tom_L: but i was counting on that
10:35 PM Tom_L: i put some grass seed down
10:35 PM rue_mohr: oh I wonder how the greenhouse tank is doing
10:36 PM rue_mohr: it was pretty close to topped the last time I looked
10:37 PM rue_mohr: https://www.thingiverse.com/thing:4874924
10:37 PM rue_mohr: over 300 downloads
10:37 PM rue_mohr: where do you think they all go?
10:46 PM Tom_L: on the DB9 thing?
10:46 PM Tom_L: who knows
10:47 PM Tom_L: most of the comments on my yt are foreigners
10:47 PM rue_mohr: hmm
10:50 PM Tom_L: i'm pretty sure i don't have to worry about my spindle stalling anymore
10:50 PM rue_mohr: might have to worry about the belt tho
10:50 PM Tom_L: no
10:50 PM Tom_L: i went pretty large on it
10:51 PM Tom_L: 15mm wide GT2 5mm pitch
10:51 PM Tom_L: all i could fit on the spindle
10:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Pulley1.jpg
10:52 PM Tom_L: i undercut it to fit over the nut
10:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Pulley2.jpg
10:53 PM rue_mohr: hah, I forgot its a gearbelt now
10:53 PM Tom_L: definitely won't slip
10:53 PM Tom_L: the other one was GT2 2-3mm? 9mm wide
10:54 PM rue_mohr: do you think you ever want to upgrade that sherline spindle block?
10:54 PM Tom_L: lot bigger teeth on the new one
10:54 PM Tom_L: no
10:54 PM Tom_L: i'll make do with it as is
10:54 PM Tom_L: wish? yes
10:55 PM Tom_L: realistically it is what it is
10:55 PM Tom_L: i may have to replace the tube at some point
10:59 PM Tom_L: yeah with the stock sherline belt, i'd burn one up in an evening easy
11:14 PM rue_mohr: :)
11:14 PM rue_mohr: I been eyeing the wear on the one here
11:14 PM rue_mohr: its halarious but those gaskets are doing great on the other one
11:21 PM rue_mohr: ok
11:21 PM rue_mohr: --- this week ---
11:21 PM rue_mohr: install/mount the driveway sensors
11:22 PM rue_mohr: setup/install/mount the wifi event transmitter
11:22 PM rue_mohr: fix the jukebox
11:22 PM rue_mohr: set up arduino for the esp32
