12:00 AM rue_shop1: damnit, I'll need a new milk crate
12:18 AM rue_shop1: all 400ppr steppers seem to have a not-5mm shaft
12:31 AM rue_shop1: ok this is stupid, every time I find a nice motor I put it in the reprap supplies box, there are enough steppers in there to build freaking 10 more printers
12:31 AM rue_shop1: JUST USE ONE OF THE DAMN MOTORS
01:40 AM rue_shop3: 4 parts to print, 4 printers :))))
01:42 AM rue_shop1: tho, I still find myself,.... waiting...
01:42 AM rue_shop3: arg, there are stepper motors everywhere now
01:42 AM rue_shop3: I need more milk crates
01:51 AM rue_shop1: hmm race of the printers
01:53 AM rue_shop1: ok, stepper has new connector...
01:57 AM rue_shop1: so 400ppr is
01:57 AM rue_shop1: 0.9 degrees
01:57 AM rue_shop1: and the gear ratio is 14:222
01:58 AM rue_shop1: putting it at 0.057 degrees, before microstepping
02:08 AM rue_shop1: oh yEaaaaa, it never ran that good before
02:08 AM rue_shop1: too bad some of the teeth are mashed up a bit
02:11 AM rue_shop1: ok stepper driver
02:11 AM rue_shop1: lets see
02:11 AM rue_shop1: we need a power supply
02:11 AM rue_shop1: 12V
02:12 AM rue_shop1: 750mA will do
02:12 AM rue_shop1: so
02:12 AM rue_shop1: 12V power connector
02:12 AM rue_shop1: motor connector
02:13 AM rue_shop1: and a 3 pin, for ground, step and dir
02:13 AM rue_shop1: should do
02:27 AM rue_shop3: so
02:27 AM rue_shop3: for 0 to 360 degrees
02:28 AM rue_shop3: laseron();
02:28 AM rue_shop3: image()
02:28 AM rue_shop3: laseroff()
02:28 AM rue_shop3: image
02:28 AM rue_shop3: angle++;
02:28 AM rue_shop3: .
02:28 AM rue_shop3: image
02:28 AM rue_shop3: take picture
02:28 AM rue_shop3: send to server
02:29 AM rue_shop3: filename = angle-laser_flag
02:29 AM rue_shop3: I'm out of juice, damn
02:30 AM rue_shop3: only 12:30
02:30 AM rue_shop3: atg
02:30 AM rue_shop3: arg
05:04 AM flav0r: my 2019 resolution
05:04 AM flav0r: to get to 500 aliexpress orders
05:08 AM veverak: lol
05:13 AM flav0r: well not 500 in the year
05:13 AM flav0r: just up to 500
05:13 AM flav0r: im at 421 now !
09:59 AM squirrel1 is now known as veverak
10:54 AM tsglove: flav0r, what do you usually order?
11:31 AM rue_bed: I used to order chips, microcontrollers, sensors, components, modules motors, batteries...
11:32 AM rue_bed: but the shipping just went up to $6-10/item which makes it not worth it for most items
11:32 AM rue_bed: would you buy a $1.50 microservo that had $6 shipping on it?
11:49 AM Tom_L: `-*/
11:50 AM LoRez: rue_bed: that would just incentivize me to buy a handful of them
12:14 PM rue_mohr: depends how they did the shipping
12:14 PM rue_mohr: lots of them go up as the numbers do
01:22 PM rue_shop1: I'd like to have a good lunch, but all the supplies went bad
01:22 PM rue_shop1: their not even unwrapped yet
02:43 PM Tom_L: some things need refrigerated ya know
02:44 PM * Tom_L offers rue_shop1 some waldorf salad
03:17 PM rue_mohr: you cant refridgerate fresh things for 4 weeks
03:33 PM Tom_L: well.... that's kinda a given
03:40 PM rue_mohr: if I want anything I dont ahve I better get it now
03:40 PM rue_mohr: and based on parking yesterday, I should just walk to the store
03:41 PM rue_mohr: cause my driveway is prolly the closest place to park
03:41 PM Tom_L: :)
03:41 PM rue_mohr: and I need to scramble to get ahead of zhanx on the 3d scanner
03:42 PM rue_mohr: I'v only been at it like 16years now
03:42 PM rue_mohr: Dec 2000, 18 years... 19? ugh
03:42 PM rue_mohr: -rwxrw-rw- 1 rue rue 310 Dec 22 2000 scanlib.h
03:43 PM rue_mohr: in 2003 I wrote a todo list
03:43 PM Tom_L: off the cam on to the printers
03:44 PM rue_mohr: well, I have all the printers I need
03:45 PM rue_mohr: they could use some upgrades, but 4 is enough
03:45 PM rue_mohr: (unless I'm trying to use up the bin of parts, in which case, 10 more...)
03:47 PM rue_mohr: I wonder if the camera auto-adjustment will screw up the line detector
04:42 PM rue_mohr: score
05:04 PM rue_shop3: whats gonna be more stable as a half hour timer, a 555 or a tiny13
05:47 PM deshipu: a well-tuned tiny13
05:59 PM rue_shop1: well, its been over 20 mins and the "6 min" 555 timer hasn't finished its cycle
06:25 PM rue_shop1: its still going
06:25 PM rue_shop1: this is what I get for internet schematics
06:25 PM rue_shop1: nobody ever tries them, they just do the math and post the simulator schematic
06:53 PM rue_shop1: relay pull in about about 90amp-turns
06:53 PM rue_shop1: relay pull in about about 90amp/turns
06:53 PM rue_shop1: so, to trip at 6A
06:54 PM rue_shop1: 15 turns
06:54 PM rue_shop1: I wonder what a reeds level is
07:03 PM rue_shop1: ooo securrity sensors
07:03 PM rue_shop1: lots of themm..
07:06 PM rue_shop1: 25amp-turns!
07:06 PM rue_shop1: SWEET
07:06 PM veverak: I just found shitload of LEGO
07:06 PM veverak: from my childhood
07:06 PM veverak: tbh I am suprised I stopped playing with it at 2AM
07:10 PM rue_shop1: :)
07:11 PM rue_shop1: 6 turns gives me a 6A trip on the reed switch
07:11 PM rue_shop1: this will be the sensor for my reprap overload
07:15 PM rue_shop3: yes yes ok
07:16 PM rue_shop3: ok, 3 wire
07:16 PM rue_shop3: big in, big out, and small ground
07:16 PM rue_shop3: DIN
07:16 PM rue_shop3: trip led
07:18 PM rue_shop3: haha, I naturally spread out into enough projects that I dont finish anything
07:19 PM Tom_L: it keeps you occupied
07:21 PM rue_shop1: hmm :/
07:21 PM rue_shop1: 8A relay for a 6A breaker?
07:22 PM Tom_L: i'm currently unoccupied
07:22 PM rue_shop1: otherwise its gettin a bit big
07:23 PM rue_shop1: you know, I could ALMOST pack this into the extra space of a cube relay
07:25 PM Tom_L: are you short on space?
07:28 PM * rue_shop1 steps over the box of sensors to type a reply and almost ends up on his head
07:29 PM rue_shop1: I'm ok on space, I just have too much stuff
07:29 PM rue_shop1: fur needs space
07:33 PM rue_shop1: ok, so the list is stacking up
07:33 PM rue_shop1: I have a motor driver board to put togethor for the 3d scanner
07:33 PM Tom_L: supposed to go the other way
07:33 PM rue_shop1: a timer circuit to make for the rice cooker
07:34 PM rue_shop1: and two electronic breakers to make for the reprap rack
07:34 PM Tom_L: how big?
07:34 PM rue_shop1: 6A
07:34 PM Tom_L: you want some din rail ones?
07:34 PM rue_shop1: gonna print a case
07:34 PM rue_shop1: but
07:34 PM rue_shop1: well
07:35 PM rue_shop1: 6 turns on a securrity door sensor hall is the sensor
07:35 PM rue_shop1: goes to a 555
07:35 PM rue_shop1: the 555 latches and drives the relay
07:35 PM rue_shop1: + reset button and led
07:35 PM rue_shop1: simple
07:35 PM rue_shop1: but
07:35 PM rue_shop1: I wanted relays with NC contacts and I dont have any that will do nicely
07:36 PM Tom_L: https://mesaus.com/index.php?route=product/product&path=74_77&product_id=131
07:36 PM Tom_L: i got some of those from JT for my mill
07:37 PM Tom_L: not cheap chinese junk
07:37 PM Tom_L: those failed me

08:08 PM rue_mohr: tom, I'm only at 6A tho
08:09 PM rue_mohr: well less
08:09 PM rue_mohr: the power supply in use is 5A
08:09 PM rue_mohr: iirc the draw is 3.5
08:10 PM rue_mohr: I think facebook is getting lonley, my emails have gone up like 40%
08:12 PM rue_mohr: wow, red onion is just that much stronger when its that fresh
08:42 PM rue_shop1: oh man, my projects are all criss-crossing and I dont know whats for what anymore
