00:02 armyofevilrobo-1 Ha, that one wasn’t even on my radar.
00:02 armyofevilrobo-1 Did you also look at heeks cam?
00:03 armyofevilrobo-1 https://sites.google.com/site/heekscad/
00:03 rue_shop3 hmmm
00:03 rue_shop3 does it cam?
00:03 rue_shop3 $20 eh?
00:03 armyofevilrobo-1 https://www.youtube.com/watch?v=lBUJcD6Ws6s
00:04 rue_shop3 wait, what?
00:04 rue_shop3 its $20 but its open source?
00:04 rue_shop3 its windows?
00:04 armyofevilrobo-1 yeah.
00:05 armyofevilrobo-1 It’s all schizophrenic, but.. it’s a thing.
00:05 rue_shop3 ah, and ubuntu
00:05 rue_shop3 pycam looks like its all there, but its no mastercam, so I didn't immediatly see how to use it
00:06 armyofevilrobo-1 pycam looks kinda dead.
00:08 rue_shop3 I thought it had work late 2013
00:08 rue_shop3 oh, what year is it?
00:08 rue_shop3 well, whatever
00:09 armyofevilrobo-1 hehehe.
00:09 armyofevilrobo-1 Last code change in pycam python source looks to be 2012.
00:10 armyofevilrobo-1 Last change to pycam test foler 2010. Not promising.
00:10 armyofevilrobo-1 anyhow. bed. L8rs all.
00:20 rue_house gnight
00:20 rue_house one of my SD adapters arrived today
00:21 rue_house the one I ordered after I gave up on the other two arriving
08:31 GuShH rue_house: check this out http://theawesomer.com/insane-homebrew-rocket/303503/
08:43 RifRaf|2 haha cool
09:02 GuShH RifRaf|2: yeah I was quite impressed
09:02 GuShH never seen something like it
09:03 GuShH it takes a lot to make me smile!
09:04 anonnumberanon Is there a channel for quadcopters/
09:04 anonnumberanon ?
09:05 GuShH no clue
09:05 GuShH should there be?
09:05 anonnumberanon Yeah man where else could I ask newb questions about quadcopter batteries?
09:08 deshipu #rchelis?
09:09 anonnumberanon #rchelis
09:09 deshipu hmm, or how was that channel called :/
09:09 deshipu I got there once
09:11 anonnumberanon #uav maybe
09:11 anonnumberanon nope
09:11 GuShH anonnumberanon: here you may ask, lots of rc guys
09:14 anonnumberanon they have #ardupilot
09:14 GuShH lol
09:16 anonnumberanon I made calculations for picking motors but not so sure they were correct after seeing conflicting feedback. Looking for motors and props for a 2kg quadcopter that will only hover and do lateral travel.
09:18 GuShH 2kg total with payload?
09:18 GuShH I'm pretty sure I've seen data on motor selection in some forums
09:18 GuShH probably even a calculator
09:20 anonnumberanon Yeah with payload, which is only about 300 grams.
09:21 GuShH quadcopters are the past though
09:21 ShH g
09:21 anonnumberanon >opinions
09:22 GuShH haha
09:23 Veverak yeah
09:23 Veverak octo are the future!
09:23 rue_house GuShH, haha, and thats how india got one really dizzy man into space?
09:29 rue_house heh, as they figure out how to use the wheel to get to space
09:29 anonnumberanon India has great rockets.
09:29 GuShH lmao
09:30 GuShH thailand, not india!
09:30 GuShH although they are quite influenced by them, in a way
09:30 GuShH I'd like to visit there, but not a big priority.
09:42 anonnumberanon I'm doing the research of my teammate on these motors and props that's why I'm a little grumpy.
09:42 anonnumberanon All I want to focus on is making the brain of it.
09:45 GuShH anonnumberanon: why are you doing his work?
09:45 anonnumberanon Good question.
09:47 anonnumberanon He had found a setup of motors and props and not a good battery. So I found a good battery and started looking at motors and it turns out his choice spin too fast for our application.
09:47 anonnumberanon He picked 910 KV when we may need only about 600 kv.
10:16 anonnumberanon Also I'm a big RC geek but I haven't done it in about 10 years :)
10:24 GuShH anonnumberanon: me neither
10:25 GuShH electrics weren't even a thing actually, 20 years ago
10:25 GuShH >_<
10:25 GuShH I still got my glow plug engines and airplanes
10:25 GuShH will convert to li-ion packs and modern radios one of these days
10:25 GuShH nicad was kinda crappy
10:25 anonnumberanon Yeah I started with that then my dad got into electric motors but then something terrible happened and I haven't done it since then.
10:26 GuShH anonnumberanon: oh, what happened?
10:26 GuShH I was next to a person when they got their fingers nearly chopped off by a prop
10:26 GuShH the sound, I will not forget.
10:26 anonnumberanon my dad passed away
10:26 GuShH this was when the needle adjustment was by the carb, very near the prop
10:27 GuShH then they started mounting the needles on the back of the engine
10:27 GuShH for safety
10:27 GuShH I'm sorry to hear, I got into RC after mine passed as a hobby to get my mind into something else.
10:27 GuShH Sucks but there's nothing one can do about it
10:28 anonnumberanon last summer I bought a radio and all the stuff for this plane we still have but tried starting the motor all day and gave up on that. don't know if will buy another fueled motor or if will put an electic one in place
10:28 GuShH Hrmm is your glow plug ok?
10:28 anonnumberanon (the motor is about 20-30 years old
10:28 GuShH yeah but if the bearings are fine and it still has compression it should work
10:28 GuShH given the fuel is ok and the glow plug is ok
10:28 anonnumberanon no it must have something bad deep in it
10:28 GuShH a weak glow plug starter is often the problem
10:29 GuShH could just need to be rebuilt
10:29 anonnumberanon I changed the sparkplug, had a good started, a good igniter.
10:29 GuShH it probably isn't an ABC
10:29 GuShH spark? so it was gasoline?
10:29 GuShH not nitro
10:29 anonnumberanon starter*
10:29 anonnumberanon oh not spark plug, a glow plug
10:30 GuShH I once stripped a glow plug right on the head of mine
10:30 GuShH had to remove the head...
10:30 anonnumberanon HOW?
10:30 GuShH the tiny copper washer wasn't sealing right so I overtorqued it
10:30 GuShH instead of replacing the glow plug heh
10:30 anonnumberanon Typical.. heh.
10:31 GuShH snapped clean off, but it wasn't a big deal
10:31 anonnumberanon The more I look at those FPV quadcopter setups the more I get drawn to it.
10:31 GuShH they're nice
10:32 anonnumberanon In any case for my last year in school I'm building a quadcopter's flight control module (autonomous) from scratch.
10:35 GuShH not if you keep doing everyone's homework you won't :p
10:35 GuShH haha
10:36 anonnumberanon Yeah I should go back and work on my C.
20:10 rue_house the 12 SD micro adapters arrived
20:10 Tom_itx rue_house
20:10 Tom_itx did you get your hot end fixed?
20:11 Tom_itx http://www.aliexpress.com/item/CNC-router-kit-metal-milling-machine-metal-engraving-machine-3050116C/32262332104.html
20:15 rue_house the new extruders just arrived today
20:17 RifRaf|2 you bought one? yay
20:23 rue_house I bought a 1.75@.4mm and a 3@.5mm
20:23 rue_house and a 1.75@.4mm for jester
20:23 rue_house the machine is still in the corner of shame
20:24 rue_house but, I dont think I need the new ones
20:24 rue_house after it was metioned that it might just need crisco
20:26 rue_house tom apparently there is a server issue that wont let me open that page
20:35 Tom_itx it wasn't that exciting anyway
20:50 rue_house one of the heads didn't come with a temp sensor or a liner
23:07 rue_house oh I was gonna work on the toaster oven
23:09 rue_house I had to work out where to put the SSRs
23:09 rue_house I wanted to put them in the oven but I cant see an acceptable way to do it
23:09 rue_house so I was thinking of putting them external
23:10 rue_house you know, the side case of the toaster oven is plastic
23:10 rue_house maybe I dont have to insulate it so much
23:10 rue_house I wonder how I can get around all the 120V bits for the elements
23:11 rue_house I wonder if I can just splat high temp silicone over them
23:11 rue_house that might work
23:12 rue_house maybe there is enough room to put insulation, and then a mounting plate for the ssrs
23:13 rue_house this seems like a direction
23:25 rue_shop3 Tom_itx, where did you put your temp sensor
23:32 rue_shop3 ahhh you just used regular fiberglass
23:32 rue_shop3 so I dont need the high temp stuff
23:37 wolfmanjm oh that is a zen toolworks cnc made of metal instead of vinyl, I got the local version which is vinyl panels
23:38 wolfmanjm http://zentoolworks.com/product_info.php?cPath=14&products_id=74
23:39 wolfmanjm PVC sorry not vinyl
23:43 Vrto poke
23:46 armyofevilrobo-1 rue_shop3: PID controllers and SSDs are here.
23:49 rue_shop3 oh, hmm
23:49 rue_shop3 were running out of reasons now to build this!
23:50 rue_shop3 I was at habitat for humanity, they have no suitable ogger bits
23:50 rue_shop3 I have yet to ask the rental shop if they have a snapoff
23:50 rue_shop3 heh, I have a computer power plug here rated for 15A @ 250VAC on one side and 10A@250V on the other side
23:50 RifRaf|2 auger?
23:51 rue_shop3 RifRaf|2, for making a filament machine
23:51 RifRaf|2 like a screw? ie auger
23:51 RifRaf|2 might not find much if you are searching for ogger is what i meant
23:52 rue_shop3 I walked the isles from A to Z
23:53 RifRaf|2 http://www.aliexpress.com/premium/auger.html?ltype=wholesale&SearchText=auger&d=y&origin=y&initiative_id=SB_20150113213639&isViewCP=y&catId=0
23:55 armyofevilrobots Those all look reasonably priced @Rue; what is the bore diameter and length we need with what you’re building now?
23:57 rue_shop3 well, I'll know more when there is a bit more design flushed out
23:57 rue_shop3 for $30 we can get a bit from GBS
23:57 armyofevilrobots alright. I don’t mind helping there :)
23:57 rue_shop3 I suppose we should do a predesign cobble and see what we need
23:59 armyofevilrobots Sure :)
