[00:18:29] <codepython777> rue_shop3: are you around?
[00:23:54] <rue_shop3> no, I'm kinda square
[00:23:59] <rue_shop3> why do you ask?
[00:45:03] * anniepoo is powder coating
[00:52:10] * mrdata has to fit 0.180" steel rods into 0.148" holes
[00:52:33] <orlock> freeze the rods
[00:52:39] <orlock> heat up the things with the holes
[00:53:19] <mrdata> smaller rods wont do because their strength is the only thing holding this thing together; everything is steel
[00:53:34] <orlock> get new engineer
[00:53:38] <mrdata> oh, and the rods have to turn once theyre in there
[00:53:45] <orlock> ah yur fucked
[00:53:59] <mrdata> i'm reaming out the holes to fit
[00:55:05] <mrdata> i have a tapered round file, and a 3/16" round file to finish
[00:57:46] <mrdata> what i find quite amazing about this is, if these hinges break, this entire folding shopping cart basically falls apart
[00:58:49] <mrdata> the original rivets were just a bit too small, and finally gave way yesterday
[04:25:13] <rue_house> that whole thermal fit thing is just a myth, it dosn't work
[04:34:46] <deshipu> yeah, at some point it just turns to plasma
[06:15:32] <SpeedEvil> mrdata: chucking the rod in a drill, and simply applying sandpaper can work really quite well.
[06:16:25] <SpeedEvil> Drill or file
[11:05:35] <rue_house> ARG clear sky, bright sun, raining. WTF!??!?!?!
[11:06:30] <DagoRed> Oh Canada, the weather does not stand on gaurd to me.
[11:08:36] <rue_house> er strange, when iceweasel crashed it lost all my tabs
[11:12:34] <rue_house> http://www.aliexpress.com/item/High-quality-anti-hurt-diy-scrapbooking-Ceramic-cutter-head-paper-Line-knife-paper-cutter-free-shipping/32584325270.html
[11:12:39] <rue_house> halarouis
[11:12:50] <rue_house> its a digital-free plotter
[11:13:48] <rue_house> just click, circle and drag your favorite magazine images
[11:14:24] <rue_house> hahah they make egg scicors
[11:17:24] <z64555> egg scissors?
[11:17:48] <rue_house> for breaking apart eggs
[11:19:34] <z64555> quail eggs, presumably
[11:19:40] <z64555> can double for cigars, too
[11:21:12] <rue_house> when did scrapbooking become a major industry?
[11:21:24] <rue_house> I'd have thought I'd have noticed it growing
[12:08:17] <adham128> omg
[12:08:22] <adham128> speed evil!
[12:08:27] <adham128> ur here too
[12:16:18] <rue_house> todays challange is to get him to talk
[12:28:52] <rue_house> oops aliexpress' site fell over
[12:29:12] <rue_house> CLOSED! NO MORE SALES TODAY!
[12:29:55] <rue_house> I recon that means I need to go do things
[12:30:05] * rue_house puts some pants on
[12:31:11] <rue_house> hmm, almost out of socks, I need a sunny day so I can finish my laundry
[12:32:01] * rue_house looks outside
[12:32:10] <rue_house> well, a sunny day when ITS NOT RAINING
[12:33:42] <SpeedEvil> up here
[15:04:40] * nevodka is a complete hardware beginner
[15:04:58] <nevodka> where does one learn the fast track to robotics building
[15:14:59] <jhylands> ask google
[15:15:14] <DagoRed> nevodka: depends on what you want to do.
[15:15:20] <jhylands> google "beginner robotics"
[15:15:25] <DagoRed> Honestly, hackaday and instructables.
[15:15:41] <nevodka> DagoRed, i'd like to experiment with an rc car of sorts
[15:16:23] <DagoRed> well step 1, hack the controls.
[15:16:39] <DagoRed> Easy way is xbee + arduino. You can make a basic controller with it.
[15:16:40] <rue_house> I need to work on that hx711 cocde too
[15:16:55] <DagoRed> rue_house: you do that all the time....
[15:20:32] <rue_house> ?
[15:24:04] <rue_house> if I can get readings form the HX711, I can get the counteracting air muscle servo working
[15:24:13] <rue_house> you know what I hate about things that need to be done
[15:24:23] <rue_house> them requiring my involvement
[15:25:50] <rue_house> I have 20 LM3914 infront of me, this is inspiring
[15:26:07] <rue_house> not that I couldn't use an avr, but still, inspired.
[15:26:46] <rue_house> I'm gonna make a scope with a few of these, a few 4017 and the 1000 leds I ordered
[15:27:00] <rue_house> I got the rectangular ones
[15:27:59] <Snert_> rect frosted rgb are pretty.
[15:28:20] <rue_house> I was thinking rgb cuase I could make a 3 trace scope
[15:28:38] <rue_house> or 1 trace and cursors
[15:28:57] <rue_house> but iirc the rgb were a little big
[15:29:25] <rue_house> Tom_itx, have you need any software debounce algs you like
[15:30:06] <rue_house> hmm, its really sunny, but, will it rain again...
[15:30:27] <rue_house> I wonder if I have enough time to get out the welder and finish the hub for the mowerbot
[15:30:57] <rue_house> oh I need to go buy washers too
[15:31:18] <rue_house> oh hum
[15:31:29] <rue_house> ... I just want to sleep...
[15:31:58] <rue_house> I suppose if I'm gonna convert myself into a robot and kick around for the next 18000 years, I'll have plenty of time for sleep
[15:32:24] <rue_house> 'what do you want me to tell them about YOU?'
[19:15:06] <rue_shop3> must check if I have ocd...
[19:15:07] <rue_shop3> must check if I have ocd...
[19:15:07] <rue_shop3> must check if I have ocd...
[19:15:08] <rue_shop3> must check if I have ocd...
[19:15:08] <rue_shop3> must check if I have ocd...
[19:15:09] <rue_shop3> must check if I have ocd...
[19:15:09] <rue_shop3> must check if I have ocd...
[19:15:44] <rue_shop3> YEA i LOVE HAVING A LATHE!
[19:17:01] <orlock> DIy or store bought?
[19:17:45] <orlock> I've realised that since i'm CAD'ing up mounts for these little 150W drill motors, i may we well bench mount one and hook it up to a drive system for a little toy lathe
[19:18:13] <rue_shop3> its from china!
[19:19:29] <orlock> ahh, model?
[19:19:52] <orlock> They have tiny little CNC mills for like, $200 now
[19:21:05] <orlock> rue_shop3: Got OpenSCAD?
[19:25:03] <rue_shop3> yup
[19:25:50] <orlock> http://en.crypt.net.au/4_wheel_robot.scad
[19:26:13] <orlock> you may want to lower the $fn
[19:26:55] <rue_shop3> i use about 192 whats it at
[19:26:56] <rue_shop3> ?
[19:28:51] <orlock> 60
[19:29:47] <rue_shop3> @#%@%^@#% WHEEL!!!
[19:29:56] <rue_shop3> ARG
[19:33:55] <orlock> Oh, there were a few modules disabled for the wheels and gears
[19:34:12] <orlock> if you re-download it, it will render the bottom half of the robot completely now
[19:34:22] <orlock> just needs the caps added to hold everything in place
[19:35:04] <rue_shop3> no, problems with robot mower
[19:35:19] <rue_shop3> rebuilding the axles
[19:35:36] <orlock> ahh, axles i still need to model on this actually
[19:36:05] <Tom_itx> what are we workin on tonight?
[19:36:49] <rue_shop3> mowerbot I
[19:37:08] <orlock> Going to use 8mm threaded rod with printed surround to fit into the wheels i have
[19:37:16] <orlock> 608 bearings at each end
[19:37:23] <orlock> and printed gears
[19:37:23] <rue_shop3> your in the usa, use 5/16
[19:37:35] <orlock> aus
[19:37:40] <orlock> all metric here
[19:37:58] <rue_shop3> when did yiou move back there again!?!?!
[19:38:05] <orlock> I never moved away!
[19:38:12] <Tom_itx> not sure he ever left
[19:38:28] <Tom_itx> got married? bought a house had a kid
[19:38:30] <rue_shop3> never sure is getting shorter and shorter
[19:38:51] <orlock> house, 2 kids now
[19:38:55] <orlock> not married yet
[19:39:08] <orlock> .. i should give her that ring
[19:39:13] <Tom_itx> don't bother.. it's a waste of.... well everything
[19:39:28] <rue_shop3> ok, then, according to instructions, simply re-install the axle
[19:40:12] <rue_shop3> so, if you die and have nobody to inherrite your stuff, the govt gets it, right?
[19:40:28] <Tom_itx> or whoever breaks in first
[19:40:44] <rue_shop3> so if, you die, and have no living family members, and are $4M in debt, the govt gets that too, right?
[19:41:09] <Tom_itx> i see where this is going..
[19:41:35] <Tom_itx> debt seems to be encouraged here
[19:42:43] <rue_shop3> if I have a visa card, a master card, and a company, the company can pay a card off
[19:42:51] <rue_shop3> and i can buy things from the comapny
[19:43:06] <rue_shop3> and if the cards are paid off every month, there is no interest
[19:43:15] <rue_shop3> but would it works with two visa coards?
[19:43:26] <Tom_itx> if they are paid off yes
[19:43:38] <rue_shop3> but they dont have to be paid off at the same time
[19:43:47] <Tom_itx> no
[19:43:47] <rue_shop3> you can always have half your cards at the limit
[19:44:00] <rue_shop3> as long as they are all paid off every month
[19:44:25] <Tom_itx> you can't continue to pay one with the other
[19:44:29] <rue_shop3> or even half of them
[19:45:04] <rue_shop3> no, but how many cards would it take to be swinging $4M
[19:45:54] <orlock> rue_shop3: What sort of lathe did you end up with?
[19:46:16] <rue_shop3> :/ I'm missing a chain
[19:46:38] <rue_shop3> I got a king 10x22, which is the same as a silimar sized grizzley
[19:50:23] <rue_shop3> I need a design rule for my robots about how many things can be held togethor by the same bolt
[19:50:59] <Tom_itx> just make the threads longer
[19:51:37] <rue_shop3> its not about that
[19:51:52] <rue_shop3> its about trying to hold 7 things togethor while you get the bolt in
[19:52:21] <Tom_itx> they make clamps and jigs for that
[19:53:06] <Tom_itx> grow more hands
[19:54:30] <rue_shop3> its also about having 6 extra things fall off when you try to take 1 thing off
[19:56:26] <rue_shop3> geez, if this 'old mowerbot parts' box gets any more stuff, I'm gonna be able to assemble the origional bot
[20:01:27] <rue_shop3> yay
[20:01:28] <rue_shop3> !
[20:01:31] <rue_shop3> its re-assembled
[20:01:45] <rue_shop3> go forth little mower, mow, mow, mow
[20:02:37] <Tom_itx> mow some mo
[20:34:56] <rue_shop3> round and round it goes, .... wait... wait this isn't right....
[20:35:50] <rue_shop3> wtf!
[20:35:56] <rue_shop3> tinfoil failure!
[20:36:16] <rue_shop3> the foil around one of the fuse on one of the motor drives stopped conducting
[22:00:36] <rue_shop3> well, it took that long for it to tear something apart
