00:04 peepsalot do you have to power one or the other at all times?
00:05 Jak_o_Shadows Um, I don't think so
00:05 Jak_o_Shadows You toggle them.
00:11 peepsalot ok, so they just move whatever mechanism one way or the other, you would never power both at the same time either, right?
00:11 peepsalot i'm used to solenoids that spring back so you don't need two. i guess pneumatic solenoids don't work that way though
00:14 peepsalot i think i pretty much get it, the only thing that's bugging me is that it appears the pressure port and exhaust are swapped compared to this datasheet diagram
00:15 peepsalot http://www.numatics.com/common/PDF/microair.pdf
00:16 peepsalot unless this is a vacuum port?
00:16 peepsalot do they use these things for vacuum too?
00:19 peepsalot or do the valves not care which way flow goes
00:20 peepsalot or did someone screw these ports in backwards
00:32 peepsalot kind of amazing how much these parts would have cost new
07:55 zero_coder hey
07:58 zero_coder any rpi robots?
08:01 aemquo rpi?
08:02 Hukka raspberry pi
08:02 aemquo Ah
08:06 zero_coder aemquo: ye
08:06 zero_coder Hukka: yep
08:06 zero_coder anything?
08:10 Hukka I was too disappointed when it came. I had plans, but I moved on
08:17 zero_coder Hukka: why?
08:19 Hukka USB has so many problems
09:18 zero_coder Hukka: usb?
09:18 zero_coder u could have used the GPIO
09:54 Hukka Oh really
09:54 Hukka My bad
10:10 GuShH_ robotustra: gay ass music
10:11 GuShH_ also I told you terminator was not made out of acrylic!
10:23 robotustra_ morning
10:32 zero_coder morning
10:50 bsilvereagle morning
10:56 StrangeloveMD_ Does anybody have any idea how large dR of solder paste is during reflow?
13:03 MrCurious woo hoo $37 ebay LCD driver works great with lapdocl 100 panel. robot shall have a face!
17:13 Jak_o_Shadows Apparently FreeCAD uses the word "Pad" instead of extrude
17:20 GargantuaSauce that was like, an uncommonly good deal though
17:20 GargantuaSauce oops
17:21 GargantuaSauce up-enter in the wrong window :(
18:00 MrCurious and now my new SSD has ocked itself
18:00 MrCurious locked
18:00 MrCurious guess today will suck a bt
18:02 robotustra_ may be you had forget to pay licence for that?
18:02 robotustra_ good night
22:19 MrCurious finally got drive migrated
22:20 Jak_o_Shadows Just bought 5 stepper motors for 3.03 each
22:20 MrCurious how big?
22:20 Jak_o_Shadows sorry, stepper drivers
22:21 MrCurious even MORE interesting
22:21 MrCurious link?
22:21 Jak_o_Shadows http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=141037403675
22:22 MrCurious nicec
22:22 Jak_o_Shadows aye.
22:23 Jak_o_Shadows Also, I figure I can also use them for small DC motors
22:23 MrCurious nope
22:23 MrCurious not easily, as they take step and dir
22:24 MrCurious rather than 4 bits of input
22:25 Jak_o_Shadows ah, so you'd have to play around with that.
