01:02 rue_more AAAAAAAAAAHHHAAAAAAAAAAAAAAAAAHHHAAAAAAAAAAAAAAAA!!!
01:02 rue_more its output isn't isolated
01:06 rue_more but I like the use of a current source to supply the base
01:06 rue_more looks like the turnoff time sucks tho
05:07 ilhardDeChardi is back (gone 00:52
07:05 Tom_itx rue_more, no automated forced cooler. Just opened the door with a small fan i have pointed at it after i set the rack on top of the oven
07:09 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/boards/reflow/cooling.jpg
07:11 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/boards/reflow/cooking.JPG
07:12 Tom_itx notice the lcd with the elapsed time and temp below it. it's cooling off
08:31 GuShH Tom_itx: yummy
08:31 GuShH DINNER IS READY <flux fumes>
08:58 Carp dinner is ready xD
09:11 madist how do you ensure even heating inside an oven like that ?
09:13 madist lol. it says at the bottom "if contents ignite, keep closed and unplug the oven"
09:14 rue_more Tom_itx, do you have it apply heat while the door is open to control the cooling rate?
09:33 Carp where's the best deal online for simple hardware? nuts, bolts, etc.
09:35 DagoRed junk yard, recycling center
09:36 Carp hmm. never even asked them while i was there. next time i take scrap down I will, thanks dagored
09:38 DagoRed Thank rue_more, that trick I learned from him a few years back. He tends to make robots out of old parts. Things like old printers are FULL of good stuff.
09:39 rue_more esp the commercial mutifunction ones
10:48 basichash How can I program my robot to love me?

11:08 MrCurious PHEAR
11:12 MrCurious seems USB oscilliscope comes today
11:12 MrCurious there goes productivity for an hour
14:07 MrCurious got my usb oscilliscope
14:29 Loshki MrCurious: only an hour? You don't get much fun-time from your toys. Which scope, btw...
14:29 MrCurious http://www.aliexpress.com/snapshot/6121710145.html
14:29 MrCurious i got it to read the test squarewave
14:29 MrCurious enough to scratch the itch and let me get to work on work
14:30 Loshki MrCurious: I'd be interested to hear your opinion of it, overall...
14:42 robotustra_ neck printing started
14:42 SlaveToTheSauce neck printing?
14:43 robotustra_ yes, neck for robot head
14:43 robotustra_ robot's head
14:43 SlaveToTheSauce printing on what?
14:44 robotustra_ 3d printer
14:44 robotustra_ :)
14:44 SlaveToTheSauce the new delta?
14:44 robotustra_ yes
14:44 SlaveToTheSauce sweet
14:44 robotustra_ yep
14:44 SlaveToTheSauce how'd the assembly/tuning go?
14:44 robotustra_ I finished it yesterday
14:45 robotustra_ already printed 2 housings for fans
14:45 robotustra_ how the real job
14:46 robotustra_ now I can print different garbage
14:47 SlaveToTheSauce hooray
14:47 robotustra_ like quadrucopters and etc etc
14:47 SlaveToTheSauce so you're happy with it?
14:47 robotustra_ yes
14:47 robotustra_ quite happy
14:48 robotustra_ table is heating 10 minutes till 90 degree
14:48 SlaveToTheSauce so you're doing abs?
14:49 robotustra_ yes
14:49 robotustra_ I'm newbe, printing just 3rd part in my life
14:49 robotustra_ I want to print polycarbonate and nylon
14:50 robotustra_ but not with this head
14:50 SlaveToTheSauce hope you have suitable ventilation
14:50 robotustra_ this head is with PEEK
14:50 robotustra_ it doesn't smell at all
14:50 robotustra_ and room is ventilated good
14:50 SlaveToTheSauce printing nylon discharges HCN gas
14:50 SlaveToTheSauce just fyu
14:51 SlaveToTheSauce so you'll want some sort of fume hood
14:52 Tom_itx robotustra_ is it the newer delta design?
14:55 robotustra_ it's rostock max v2
14:55 robotustra_ I don't know if it's new new
14:56 robotustra_ I'm going to make a housing for it anyway, because as for me it's loude
14:57 robotustra_ estimation time 3 h 33 min
15:00 robotustra_ the only issue that I have to unwind filament manually because I don't have spool
15:00 robotustra_ may be I have to print one
15:00 Tom_itx or make one from wood
15:01 Tom_itx etc
15:01 Tom_itx find an old wire spool from an electric shop
15:02 robotustra_ I need it dissasembling, to be able to put a roll of filament on it
15:02 Tom_itx so make it that way
15:03 robotustra_ I saw a lot of spools on thingerverse
15:03 Tom_itx i'm sure
15:04 robotustra_ ops
15:04 robotustra_ 27.7 meters of filament
15:07 robotustra_ ah, ok it's not so much filament
15:07 robotustra_ 35 turns
15:07 robotustra_ coils
15:14 robotustra_ I would make it form wood if I had wood in this appartment
15:14 robotustra_ to gel some wood I have to go to the shop and buy it
15:14 robotustra_ that part I don't like
15:16 robotustra_ I thought that I'll remake deltas to carbon fiber tubes, but I see these chipskates work good for now
15:16 robotustra_ so I let them work
15:17 SlaveToTheSauce most filament suppliers ship it on spools anyway
15:20 robotustra_ but not chinise
15:21 robotustra_ they sell it by 900 g and without spools
15:21 robotustra_ http://postimg.org/image/vhv7hg2z5/
15:22 robotustra_ yesterdays print
15:22 robotustra_ it's layer fan housing
15:22 robotustra_ but I don't need it when print ABS
18:57 Tom_itx http://www.electronicproducts.com/Computer_Systems/Servers/HP_initiates_computer_revolution_with_machine_that_calculates_640TBs_of_data_in_one_billionth_of_a_second.aspx#.U6oL-nY_HrQ
19:03 Skwint yeah, but it doesn't seem to have any pwm connectors so it kinda sucks
19:11 MrCurious is anyone working using robotics with renewable energy or recycling?
19:27 MrCurious when is it legal to bite an oponent in futbol?
19:28 Tom_itx when the ref isn't looking
19:29 Tom_itx maybe he was hungry
19:40 MrCurious http://img.thesun.co.uk/aidemitlum/archive/02003/Caro-england_2003122a.jpg
19:44 MrCurious there is a better one of him playing wearing one of those white dog megaphone scratch collars
20:21 MrCurious due to this illegal imigrant bum rush, every carton in america has a different childs picture on it
20:26 Tom_itx steps should (could) have been done to prevent it
20:28 MrCurious i think its because the children of south america have taken pitty on america for only having crappy futbol players, and are now making personal sacrifices to change that
22:50 rue_more well, the trenching has begun
22:51 rue_more and some pipes were hit that lead me to believe this yard still has surprises
22:53 orlock scary
22:53 orlock what sort of pipes?
22:54 orlock a pair of A4988's arrived today for me
22:55 orlock I'm sure you'll laugh, but i just ws h the shed wasnt SO FUCKING COLD
22:57 orlock Major river here broke its banks yesterday - i do not remember that ever happening
23:31 MrCurious a4988 s that a motor/stepper driver?
23:31 MrCurious sounds super familiar
23:31 MrCurious you responded too slow, googling
23:32 MrCurious stepper driver
23:35 orlock yeah little cheap thing, apaprently used in 3d printers a lot
23:35 orlock variable step size, and came with an itty bitty heatsink
23:35 orlock must be about 4mm a side
23:35 MrCurious found a sneak peak at ep 1. of next seasons game of thrones https://www.youtube.com/watch?v=2EoQCtPR2-I&feature=youtu.be
23:35 MrCurious http://www.ebay.com/itm/CNC-Router-Single-1-Axis-3A-TB6560-Stepper-Motor-Driver-Controller-Board-New-/271507041391?pt=LH_DefaultDomain_2&hash=item3f3714ac6f
23:36 MrCurious if size is not an issue....
23:36 MrCurious ebay has some big honkin drivers with more features, decay, duty cycle...
23:37 MrCurious i used the ezdriver http://www.schmalzhaus.com/EasyDriver/EasyDriver_v43/EasyDriver_V43_Description.png but i blew 2 of them then moved to something with more beef
23:38 MrCurious <STRONG>NOTE</STRONG> i am not an expert
23:38 GuShh_Lap MrCurious: so cut or no cut?
23:39 MrCurious havent tried the big ones syet
23:39 MrCurious 13 hour work day
23:39 GuShh_Lap pft.
23:40 MrCurious darn corporate america and their promise of bonus''s and their bountiful paychecks, buying my unadulterated love
23:40 GuShh_Lap 'murica
23:40 MrCurious i worked out why all the kids from south america are flooding into USA
23:40 MrCurious and its nothing lilke what the media thinks
23:41 MrCurious it seems the shitty performance of the USA team over the year shas garnered their attention and pitty, and now they are willing to brave the journey in the hopes of joining our team and helping us not to suck so bad
23:50 Shh_Lap doesn't know what MrCurious is talking about but it's probably to cover the fact his saw can't cut the hardened
23:50 Shh_Lap goes to bed ... 1:32A
23:51 MrCurious leave my rod alone. its plenty hard
23:51 GuShh_Lap ;)
23:52 MrCurious https://www.youtube.com/watch?v=mZqWw-xdy9I
23:52 MrCurious ok, this scope does NOT lookhorrid
23:52 MrCurious really wish they had used a different sound track than the one from 2girls1....
23:53 GuShh_Lap meh usb scopes are for kids to probe their testies with.
23:54 MrCurious does that produce interesting graphs?
23:54 MrCurious does yours do e-tricks?
23:59 orlock heh
23:59 orlock pretty sure my scope has a USB interface.. but its for output
23:59 orlock it also runs WinME :-\
23:59 orlock stupid fucking overkill thing
23:59 MrCurious the scope was $72
23:59 MrCurious i will only use it for arduino like circuits
