00:31 rue_house MrTrick, we program the avrs direct, try #arduino?
00:31 MrTrick no worries, thanks.
00:53 rue_bed !seen shuggins
00:53 tobbor I have never seen shuggins
00:53 rue_bed ugh
00:54 rue_bed !seen shuggans
00:54 tobbor shuggans was last seen in #robotics on Jan 28 03:35 2013

00:54 tobbor My watch says its 10:45PM Tue Jan 29 2013
00:54 rue_bed hmm
06:41 MaoIsAcat hi
06:42 MaoIsAcat I have a question about a robot sumo
06:44 GuShH why is everyone asking about sumos
06:45 GuShH what sort of newmedia bullshit featured them that now everybody wants one?
06:45 GuShH maybe fox news?
06:45 GuShH they're older than you!
06:45 GuShH as are quadcopters.
06:45 GuShH go build something new and useful instead
06:45 ShH slaps MaoIs
06:46 MaoIsAcat xD
06:46 MaoIsAcat Askto all school teachers.
06:46 MaoIsAcat ask to
06:47 GuShH ?
06:47 GuShH maybe they're the ones pushing the sumo shields and thus want to increase sales
06:47 GuShH I mean if I were a proper asshole I'd do that.
06:47 ShH stares at the
06:48 MaoIsAcat What do you have against it?
06:48 GuShH So having an opinion means you have something against it
06:48 GuShH ?
06:48 MaoIsAcat no, its only a question
06:48 GuShH I don't like makers, arduinians or any of that bullshit
06:49 MaoIsAcat What do you prefer?
06:49 GuShH I think they should all move to an island and quit bothering the rest of us
06:49 GuShH So you see, I knew you were one of them.
06:49 MaoIsAcat GuShH , a bad day?
06:49 dunz0r MaoIsAcat: Don't worry, he's usually like that.
06:49 GuShH MaoIsAcat: you all ask stupid questions because you don't know what you're doing and it's all caused by being spoon fed
06:50 GuShH it's always the same every day
06:50 MaoIsAcat Im trying to learn
06:50 GuShH you are doing it wrong
06:50 MaoIsAcat maybe
06:50 GuShH throw away all the hipster crap
06:50 dunz0r He hasn't asked any question yet even. Chill
06:50 GuShH dunz0r: He has
06:50 dunz0r GuShH: Ah, yes he has. Not about robotics though.
06:51 GuShH True
06:51 MaoIsAcat I havent time to ask the question.
06:51 GuShH MaoIsAcat: So ask
06:51 GuShH You do have time
06:51 GuShH We can argue and talk robotics at the same time
06:51 GuShH it's 2013!
06:52 GuShH dunz0r: is there a wiki for this chanel? all newcomers should be pointed to it and a lot less time would be wasted
06:52 dunz0r GuShH: Not that I know of. I agree that there should be one.
06:53 MaoIsAcat I'm doing my robot design. And I was thinking how to put things (arduino, shield, battery...), for get better grip
06:53 GuShH That made no sense
06:53 dunz0r MaoIsAcat: As much weight on the wheels as you can.
06:53 GuShH You mean lowering your center of gravity?
06:53 GuShH For stability
06:53 GuShH Or how to actually design the housing?
06:53 dunz0r MaoIsAcat: Low center of gravity and as much weight as possible on the wheels.
06:53 ShH twitches at vague quest
06:54 MaoIsAcat becaouse i have two motors, with two wheels, and a free wheel at the front
06:54 dunz0r MaoIsAcat: Make sure you have some weight in fron too, so it doesn't flip over, do wheelies etc.
06:55 GuShH but wheelies are fun
06:55 dunz0r GuShH: Indeed they are, quite impractical in robot-sumo-matches though.
06:55 GuShH unless you are showing off !
06:55 dunz0r I put weights on the front of my last sumorobot since it would flip over all the time if I didn't
06:56 MaoIsAcat i was thinking in putting the battery under the base to get better center of gravity
06:56 Jak_o_Shadows I was thinking of putting an arduino on my robot, just to get analog readings into the computer. The motor control will still be through a msp430 though.
06:56 GuShH MaoIsAcat: shift it forward a bit also
06:56 k_o_Shadows g
06:57 GuShH Jak_o_Shadows: there's a difference between knowing your tools and utilizing them to their best potential
06:57 GuShH and being misled into buying crap and not knowing what to do with it.
06:57 MaoIsAcat yes, i think so GuShH
06:57 GuShH or rather, not knowing any better.
07:31 Tom_itx or you could answer the question instead of ranting
07:37 GuShH Tom_itx: see, that's your opinion. why don't you answer instead, otherwise you are part of the problem.
08:07 orlok W00t!
08:08 orlok i am Home.
08:08 theBear GuShH, what, i'm the proper asshole ? spose it's kinda a compliment :) and sumos don't use shields, they just grow their tummies and arms
08:09 orlok theBear: YO!
08:10 orlok i have a Shed. and Workshop.
08:10 orlok ad house along with it
08:10 theBear GuShH, and there aint a wiki i know of either, but rue's page has lots of good beginner tutorials, including servos and probably steppers, lots of theory, avr programming, etc etc
08:11 theBear wow, nice
08:11 orlok and a view of the dendanongs
08:11 orlok dandenongs
08:11 orlok well, viewof their north face
08:11 orlok its awesome
08:12 orlok house, view, internet, workshop, shed, the works
08:13 orlok no mobile reception, but 15Mbps internet
08:14 orlok well, i get reception.. if i sit on the balcony..
08:14 orlok with the mountain view!
08:14 orlok :)
08:15 orlok its so awesome
08:15 orlok daughter loves it
08:15 orlok parrots eating birdfeed on the balcony
08:15 orlok huntsmans trying to type on the keyboard
08:18 theBear mmm nice... some buddies used to live in a place out of berowra kinda way where you walk out the back and all you can see is trees and hills :)
08:18 theBear heh re typing
08:23 orlok this place is awesome
08:23 orlok bubby loves it
08:27 theBear hooray !
08:27 theBear in the last 24hrs i had a cat visit twice, and a dog visit,hmm, maybe twice also... they seem to not dislike it :)

17:11 ZinnSoldat heyho anyone there?
17:16 IanWizard-Cloud I need a somewhat (within 5 ft or so), reasonable way, to detect the distance to the ground. However, the ground may be any number of sand, dirt, cement, tree cover, water, etc.
17:46 ace4016 IanWizard-Cloud, sonar and/or range finder
18:11 IanWizard-Cloud ace4016: it was my (limited) understanding, that sonar is fairly unreliable on uneven surfaces.
18:45 ace4016 how accurate are you looking for?
18:48 Tom_itx (within 5 ft or so)
21:20 rue_shop3 !?! I have no tiny85?
21:20 rue_shop3 tonne of tiny13
21:24 rue_shop3 Tom_itx, 20 min project for a newb, 555 flasher?
21:24 rue_shop3 all spelled out?
22:19 Tom_itx possibly
22:52 rue_house ok I'v written day 1 for a newb
22:52 rue_house and I'v prepped 2/3 of the activity material
22:52 rue_house gets easier as it goes along
22:55 Tom_itx you ever used progmem?
22:55 Tom_itx need a char string[] = "Hello World"
22:55 Tom_itx line initialized
22:55 Tom_itx i keep getting errors
22:56 Tom_itx i'll check in the AM
23:02 rue_house no
23:10 Tom_itx well i just need a char array
23:10 Tom_itx for a string
23:11 Tom_itx i'm a bit rusty
23:13 IanWizard-Cloud ace4016: well, within a foot or so would be nice.
23:15 Lola8088
23:26 rue_house hmm
23:26 rue_house you say
