01:29 AM rue_bed: --
04:36 PM zhanx: rue_mohr, I believe the post office now hates you
04:36 PM zhanx: The condition of that envelope, wow
06:18 PM Tom_L: it arrived. the rest is optional...
06:48 PM Tom_L: zhanx any progress on the printer diagnosis?
06:49 PM zhanx: just sat down
06:49 PM zhanx: and no
06:51 PM Tom_L: he sent you encoder wheels?
06:52 PM zhanx: yep
06:52 PM zhanx: 5\
06:52 PM Tom_L: 5mm hole iirc
06:53 PM Tom_L: these: http://tom-itx.no-ip.biz:81/~webpage/rue/encoder/encoder_wheel_30a.jpg
06:54 PM Tom_L: or these: http://tom-itx.no-ip.biz:81/~webpage/rue/encoder/encoder_wheel_30.jpg
06:54 PM Tom_L: probably the first one
06:59 PM zhanx: first ones
07:04 PM zhanx: its like sink or swim, I am booked now for saturday
07:04 PM Tom_L: that's good i guess..
07:04 PM zhanx: x-mas is coming, and its money so its good
07:05 PM zhanx: I charge more on weekends anywauys
07:06 PM Tom_L: dammit, i should have soldered the memory slot connectors too while i had the MB out
07:07 PM Tom_L: hdd kept failing but it's fixed now but i'm getting memory errors...
07:07 PM Tom_L: P166
07:07 PM Tom_L: i'm nearly sure it's the solder joints
07:08 PM zhanx: toss it in the oven
07:08 PM Tom_L: probably melt something else
07:09 PM Tom_L: at least it's _real_ solder
07:24 PM Tom_itx is now known as Tom_L
07:25 PM rue_mohr: zhanx, were the encoders ok?
07:25 PM rue_mohr: I just re-used toms packing material
07:26 PM rue_mohr: well, I added a few things to it
07:26 PM zhanx: yes they were ok
07:26 PM Tom_L: hah it's not my fault!
07:26 PM rue_mohr: cool
07:26 PM zhanx: I just feel bad for the machine that ate them
07:26 PM rue_mohr: I kinda wondered when she just accepted it as a letter
07:27 PM rue_mohr: I was just kinda like "well, its her call!"
07:27 PM Tom_L: so did i but you got them ok right?
07:27 PM zhanx: all 5 were poking out and the envelope was torn from halfway on
07:27 PM rue_mohr: thats a hell of a lot of layers to have worn thru
07:27 PM zhanx: what layers?
07:27 PM Tom_L: mine told me they wouldn't machine process the letter
07:27 PM zhanx: it was 5 in the envelop
07:28 PM rue_mohr: apparently canada post let go of all the humans, so everything is machine processed
07:28 PM Tom_L: maybe they repackaged it?
07:28 PM zhanx: beats me, I got a torn letter with 5 encoders in it
07:28 PM rue_mohr: zhanx, were they taped to a blue card?
07:28 PM zhanx: nope
07:28 PM rue_mohr: Tom_L, it was blue, wasn't it?
07:29 PM Tom_L: my card stock was
07:29 PM Tom_L: yeah they repackaged it i bet
07:29 PM zhanx: they were just in the taped up envelop rue, nothing else
07:29 PM rue_mohr: hu
07:29 PM zhanx: Tom_L, that means rue_mohr is on a list now
07:29 PM rue_mohr: so much for my letter to z
07:30 PM Tom_L: and you wonder why i don't say much :)
07:30 PM rue_mohr: hah
07:30 PM zhanx: you only sent 5 right?
07:30 PM rue_mohr: yup, it was 5
07:30 PM rue_mohr: iirc
07:30 PM zhanx: k at least the important stuff made it
07:30 PM Tom_L: cause 5 is such an even number...
07:30 PM zhanx: I know right?
07:31 PM rue_mohr: the encoders just arrived today
07:31 PM rue_mohr: er, the interrupters
07:31 PM rue_mohr: https://www.aliexpress.com/item/RPI352-RPI-352-PHOTOINTERRUPTER-ULTRAMINI-50pcs/32722756130.html
07:33 PM zhanx: back is killing me, debating going out to the truck and getting the tools to ground this printer
07:33 PM rue_mohr: you gonna build a motor tester?
07:33 PM rue_mohr: er, driver tester
07:33 PM zhanx: yes
07:34 PM zhanx: I need to
07:34 PM rue_mohr: thats what I'd do with them,
07:34 PM rue_mohr: breadoard and test all 8
07:34 PM zhanx: I have a ton to test and yes
07:34 PM zhanx: I got the arduino uno and the bread board out
07:34 PM rue_mohr: you want a 12V and 5V power supply, shortable
07:35 PM zhanx: I only have a 5v shortable
07:35 PM zhanx: unless that 12v one from amazon can handle it
07:35 PM rue_mohr: the 12V 500mA will short ok, wont it?
07:35 PM Tom_L: put a resistor on the 12v
07:36 PM rue_mohr: most of the pins are silly straightforeward
07:36 PM rue_mohr: and I dont suggest using an arduino to test it,
07:36 PM rue_mohr: you want something that cant blow up, a 555 even
07:36 PM zhanx: i have like 15 esp8266's I can waste on it\
07:36 PM rue_mohr: 2 grounds, 1 vcc, 1 +v for motor
07:37 PM rue_mohr: esp8266 is 3V, wouldn't do that
07:37 PM rue_mohr: esp cause i think a few of your drivers have the 12V shorted to the 5V
07:37 PM zhanx: i run them at 5v all the time
07:37 PM rue_mohr: which is why I usggest the 555
07:37 PM rue_mohr: 4 pins go to the motors
07:37 PM zhanx: ok I will order some 555's as i have not used them in forever
07:38 PM rue_mohr: do you have anything else on hand to make an oscillaotr? some transistors maybe?
07:38 PM rue_mohr: you dont ahve a 555??
07:38 PM rue_mohr: dead computer supply, LM393
07:38 PM zhanx: think i have a few lm393's
07:39 PM rue_mohr: (8 pin dip used for the regulator feedback)
07:39 PM rue_mohr: if so, lets start with an osc from the lm393
07:39 PM zhanx: I can get 4 555's to the house for 39 cents
07:39 PM rue_mohr: in a month?
07:39 PM rue_mohr: if you have the 393, lets do that
07:39 PM zhanx: no by monday
07:39 PM rue_mohr: too long
07:40 PM zhanx: you do realize I have 5 backup drivers right?
07:40 PM rue_mohr: 1x 1k resistor, 4x 10k resistor, 1x 0.1uF capacitor
07:40 PM rue_mohr: I'm sorry this project isn't being kind to you
07:41 PM rue_mohr: I really wish I could pinpoint what the hells going wrong
07:41 PM rue_mohr: the drivers weren't running really hot were they?
07:41 PM zhanx: its ok, and my electronic supplies suck remember? I never replaced 90% of the stuff I left in New orleans a few years ago
07:41 PM zhanx: nope not hot
07:41 PM zhanx: I think, one of the heat sinks shorted out a pin
07:42 PM rue_mohr: got that lm393 in the breadboard?
07:42 PM rue_mohr: and the 5V?
07:43 PM rue_mohr: have a foot of cat5e to make jumpers?
07:43 PM zhanx: have jumpers, breadboard, 5v, looking for the chip
07:43 PM rue_mohr: pin 4 to ground
07:43 PM rue_mohr: pin 8 to 5V
07:43 PM rue_mohr: freq out is pin 1
07:44 PM rue_mohr: pin 1 needs a 1k pullup
07:44 PM zhanx: rue my back is killing me, i am not digging for it tonight, I am hurting too much
07:45 PM rue_mohr: damn
07:45 PM zhanx: it still flairs up once in a while and today its just plain bad
07:47 PM zhanx: brb need to call UNIS about some of these work orders and parts they are late on shipping
07:47 PM * rue_mohr closes lm393.pdf
07:51 PM zhanx: of course i get put on hold
08:15 PM zhanx: oj lovely
08:15 PM zhanx: oh*\
08:15 PM zhanx: I was on hold till they closed and then they forwarded me to voicemail
08:33 PM Tom_L: fun
08:41 PM zhanx: my robot arm?
09:02 PM rue_mohr: I dont know, you were interested
09:04 PM zhanx: k
09:04 PM zhanx: I found the sensors I saved for them
09:04 PM zhanx: Think it was the arm
09:05 PM zhanx: I have 5 dc motors also
09:05 PM zhanx: must be it
09:10 PM zhanx: rue_mohr, ever work on a printer that printers, folds, inserts and mails stuff?
09:11 PM zhanx: I worked on one today, it was british, the manual was awesome. and the machine basically told me what was wrong after diagnostics
09:12 PM zhanx: feed for the water to lick the envelopes was clogged and it knew it
09:13 PM zhanx: too bad i had to tear it down like 80% of the way to fix it
09:20 PM rue_mohr: cool
09:22 PM zhanx: i got a pic of the guts i think
09:22 PM zhanx: rue you on email computer?
09:23 PM zhanx: i will imgur so Tom_L can see it
09:23 PM zhanx: its a bad pic tho
09:24 PM rue_mohr: yea
09:24 PM zhanx: https://imgur.com/a/pD0EZ0a
09:24 PM rue_mohr: ooo lotsa motors
09:25 PM zhanx: thing was like 200 pounds
09:25 PM zhanx: see the blue knob on the right?
09:25 PM zhanx: behind that is a motor the width of the machine
09:30 PM Tom_L: never seen one that did all that
09:31 PM zhanx: Tom_L, its not a tiny machine for sure
09:32 PM zhanx: tomorrow I have 3 more postal offices to upgrade the routers on and a fire alarm system and that is my morning, I am starting to sound like rue_mohr
09:33 PM Tom_L: but that's good
09:33 PM Tom_L: get it while it's there
09:34 PM zhanx: true
09:34 PM zhanx: its a pita but its working
09:34 PM zhanx: wife thinks in 5 years I can run a desk
09:35 PM Tom_L: all the paperwork slowin ya down?
09:35 PM zhanx: kind of
09:36 PM Tom_L: you need a good paper trail though
09:36 PM zhanx: i am getting a system down
09:36 PM Tom_L: organized...
09:36 PM Tom_L: it can be simple and still effective
09:36 PM zhanx: 15 days will be 1 year
09:37 PM zhanx: first year will post a profit so i can't be that messed up
09:37 PM Tom_L: just keep that up
09:38 PM zhanx: just seems like i am always on the phone or driving
09:38 PM zhanx: 12 hour days etc
09:39 PM zhanx: I need to stop at the new electronics supply store that just opened up. ALL Electrics
09:40 PM zhanx: I was surprised they called me to let me know they opened
09:40 PM Tom_L: they probably need you as much as you need them or more
09:40 PM zhanx: if it works, I can use them
09:43 PM zhanx: nice thing is on of the older electricians is refusing to do cat5 runs and wants me to do them all for termination
09:43 PM Tom_L: https://www.allelectronics.com/
09:43 PM Tom_L: them?
09:43 PM Tom_L: he's probably gettin tired of crawling around
09:44 PM zhanx: name looks right, but the logo on the store is orange not blue
09:45 PM zhanx: Bets its a company with the same name, as that company is in CA not NY
09:45 PM Tom_L: hmm
09:46 PM zhanx: I passed by them today, is all orange for the sign and the 2 trucks outside
09:46 PM zhanx: parking lot was still not paved yet
09:51 PM zhanx: ok enough work i am over stressing my self on it
10:13 PM rue_mohr: :( oh bugger, I forgot to make the collette for tom
10:13 PM rue_mohr: cant remember when I get home from work
10:13 PM rue_mohr: grrr
10:13 PM rue_mohr: ok, on to neural networks
