00:37 theBear heh, thinkin outside the box, nice work ! keep coming up with stuff like that and you're headed for a nobel prize or at least an honorary doctorate from one of the finest universities, i'm sure of it!
00:42 rue_shop3 "what happened to Peter?" "he was eaten to death"
00:50 Casper rue_shop3: surprise! the chinese replied for the pressure switch!
00:50 Casper ... and they can't provide an exploded view diagram...
00:50 Casper I guess it would be under a NDA...
00:52 rue_shop3 I thinkits more likley that they just have no idea
00:54 Casper or they have none, even for their own internal use
00:54 theBear probly not much use if they explode it first anyway, heck, it'd be a miracle if they found it all to put in an envelope after that!
01:01 rue_shop3 might ship faster
01:02 rue_shop3 theBear, what you doing for mental recreation these days?
01:06 theBear soldering tiny tiny TINY things with 1.63mm solder and a relatively normal conical tip is a common hobby... i'm down to comfortably doing .25mm pitch ic or connector pins, which is pretty damned small between pads <grin> err, i still do regular mobile and lappy fiddle/repairs for friends... those samsung guys are asshole btw, http://testing.fucking.rememberit.com.au/pics/stupid%20samsung%20microusb/2
01:06 theBear 014-12-05%2011.08.01.jpg is their new err,usb 1 or 2, just regular size micro usb pretty sure, but with 11 effing pins squeezedinto an odd spacing, that's a staight razorblade NOT fitting between a couple pins in a little cluster of 3... and they are THIN ! that's the solder job that nearly broke my patience, and i'm actively avoiding ever having to go near one again, assholes !
01:07 theBear umm, i probly do some other sutff, surely
01:21 rue_shop3 cool
01:40 theBear i sure am :)
01:40 theBear who's got two thumbs and is super cool <double thumbs up + pointing at cheesy grin> ehhhhhhh ! it's this guy !
01:41 theBear (only a very cool guy could pull off that kinda manouvere, i mean, obviously !)
02:01 rue_shop3 :)
02:01 rue_shop3 still have two thumbs eh?
04:18 rue_house ok I designed a stick-down wire anchor for the 3d printer, and I'm printing a plate of them
04:18 rue_house stick/screw
04:25 LiohAu rue_house: did you see my question?
04:40 rue_house no
04:47 LiohAu rue_house: I re-ask it then : when using a think like this : https://www.youtube.com/watch?v=31kaGTE7e3I is it what you call mouting stuff directly on the servo shaft?
04:49 Jak_o_Shadows I dunno if that's directly
04:49 Jak_o_Shadows those bearings would take all the radial force.
04:50 LiohAu yes this is basically what I was thinking, using bearings means "indirect mounting"
04:52 rue_bed its direct mounting that I was bickering about
05:28 LiohAu rue_bed: yes I know, I was asking if you still consider that it is a direct mount when you use a bearing
05:49 veverak LiohAu: indirect radial force
05:49 veverak direct axial force
05:49 veverak :)
10:09 rue_bed if your not cantalievering something off a servo shaft, your ok
10:11 deshipu there must be 50 ways to love your cantaliver
10:14 rue_bed not off a servo shaft
10:14 rue_bed not an rc servo
10:15 deshipu the rebuild of my ubob robot is complete
10:16 deshipu it uses a proper pcb this time, that I etched myself
10:16 deshipu shame the distance sensor that I put on it didn't really work
10:18 deshipu I wonder if I wired it wrong or just fried when I connected the battery wrong :)
10:50 rue_house LiohAu, just had a chance to watch the video, that fixes it, there are two points the shaft is supported on tho its quite a bit up to how you attach to that servo horn
13:03 deshipu it's raining robots again
13:04 deshipu I really think a simple wheeled or tracked robot with a single manipulator would do best there
15:09 ace4016 DARPA challenge of their rescue robot competition
15:09 ace4016 https://www.youtube.com/watch?v=8v18eAtRiCI
15:09 ace4016 if anyone was interested in watching
15:31 SpeedEvil Rescue challenge - is that where you have to build a robot to pick up all the other robots that've fallen over?
15:33 ace4016 lol seems like it
15:54 Anniepoo oops... can't get outta the car
15:55 Anniepoo One thing to point out - invariably these things were designed by *students* - while
15:55 Anniepoo I have a lot of respect for students, they are people who will soon be brand new engineers....
15:55 Anniepoo 8cD
15:56 Anniepoo (admittedly,. they have faculty advisors, but...)
16:26 ace4016 another one bites the dust
16:27 deshipu robo-parkour?
16:27 ace4016 if these robots could do parkour, i've be impressed
16:27 deshipu it's their version
16:28 deshipu they can walk over a thin book lying on the floor, for example
16:28 deshipu ace4016: do you also get only some stupid audience shots on track red?
16:29 ace4016 hrm?
16:29 ace4016 the live stream i think is on yellow track
16:29 deshipu https://www.youtube.com/watch?v=U8I4z9dLgTA
16:29 ace4016 didn't know you could switch tracks
16:29 deshipu there are live streams from all tracks
16:30 ace4016 ah, neat
16:30 deshipu if you go to http://theroboticschallenge.org you can select tracks at the bottom
16:31 ace4016 ah, nice
16:31 deshipu looks like Hercules got a leak
16:31 ace4016 yup
16:31 deshipu fortunately the disaster recovery team is do-toxifying the area so that it's safe again for robots
16:32 deshipu the team is composed of cheap expendable hoomans
16:34 rue_bed glue gun
16:34 rue_bed hydraulic pipe
16:34 rue_bed milk
16:34 rue_bed popsicle sticks?
16:36 rue_bed make disk sander
16:36 rue_bed cast pulley
16:39 rue_bed make BIG servos, stock
16:39 rue_bed take apart printer
16:40 deshipu repeat
16:43 Tom_itx rue_bed should be rue_shop3 by now...
16:47 deshipu https://www.youtube.com/watch?v=AQf0qsRTsoA <-- neat motors
17:00 rue_house I cant sleep over all the noise my mind is making
17:01 deshipu rue_house: the solution is easy, do you have an ice pick?
17:02 rue_house I was told to find a long charp stick with a hook on the end
17:02 rue_house oh great, I'm groggy, thinking too much, and half asleep
17:02 rue_house why cant everything be in the same state all the time
17:02 deshipu it will, eventually
17:03 deshipu yay, they are showing Spot again \o/
17:03 deshipu two spots!
