01:43 sw0rdfish hmmm
02:01 RifRaf avr is doing text 2 speech now, pretty neat
02:11 sw0rdfish ?
02:12 RifRaf i can issue any line of text to the avr and it turns it into speech
02:13 RifRaf pwm output to audio amplifier
02:21 theBear holy crap ! that's amazing
02:22 RifRaf yep, can speak all the commands now, can understand it 'ok'
02:23 RifRaf if i have a library of standard phrases i will soon get used to them
02:25 RifRaf am blown out with new found libs for avr
02:26 RifRaf this is wat i always needed
02:34 theBear yeah, take a 5 year break and things seem pretty fancy when you come back
02:35 RifRaf :)
02:39 RifRaf theBear have you seen the webbotlibs? its shown me so much already, like that the boards i made for avrs use all the wrong ports for pwm and stuff, gonna redo a couple of boards and get some new pcbs made
02:40 theBear nah, i aint programmed for a while

07:53 AstroBoi \o/
08:54 rue_house just talk
08:55 theBear no
08:55 rue_house hmm fighting to stay awake today
17:47 DanFrederiksen steppers are shit. you can only do serious robotics with servo motors. this is obvious to industry but the DIY crowd still has sad devotion to steppers
17:49 GargantuaSauce steppers are fine if you actually use feedback instead of pretending every step has a constant size
18:02 DanFrederiksen GargantuaSauce, why not just use servo
18:03 DanFrederiksen more powerful, more efficient
18:03 DanFrederiksen faster
18:03 GargantuaSauce but they don't make wonderful noises :(
18:03 DanFrederiksen actually they do
18:04 KimLaroux Aimless free rants
18:04 DanFrederiksen and you can't do real robotics with steppers. that's why it never happens here
18:04 DanFrederiksen diy robotics is pathetic
18:04 KimLaroux And you're not?
18:05 DanFrederiksen far from it
18:05 KimLaroux Ranting on someon'e hobby for being "wrong" is pathetic
18:05 GargantuaSauce how dare you question the polymath genius
18:05 GargantuaSauce shame on you
18:06 KimLaroux Would you prefer only engineers built everything, and the rest of the world be mindless consumers?
18:06 theBear that's how it is now :)
18:06 theBear you just don't know that we are engineers :)
18:07 DanFrederiksen KimLaroux, I'm encouraging people to think and do better. you are proposing they stay mindless
18:07 DanFrederiksen ironically
18:07 DanFrederiksen not that you will learn from your mistake
18:07 DanFrederiksen that would be thought
18:08 DanFrederiksen general availability of servo solutions in the DIY sphere would enable people to do far more
18:08 theBear you know that most of us do use feedback anywhere that it matters i assume, we sure as hell don't assume steppers always step when we tell them to
18:08 KimLaroux The best part about DIY is that you can build whatever you want, however you want, and not care how "wrong" it is. If it works, then yay.
18:08 theBear this is why salvaging from things like printers is attractive, already got high res encoders with your motors
18:09 DanFrederiksen salvage is very limiting. designing to purpose and possible series production is far more potent
18:09 GargantuaSauce and that's exactly what diy is allll about
18:09 theBear having no money is very limiting, but much less so when you salvage
18:10 theBear and hobby is NEVER about production, it's almost always guaranteed to be one-offs in this kinda place
18:10 KimLaroux Most DIY'er don't care about "possible series production". When they do, they aren't DIY anymore
18:10 theBear pfft, that guy sucks
18:11 GargantuaSauce i still can't decide if he's for real
18:11 GargantuaSauce or just an exceedingly good troll
18:11 KimLaroux Troll
18:11 Jak_o_Shadows1 I think he's just crazy.
18:11 KimLaroux lol, or that
18:11 KimLaroux it's kinda hard to make the difference between a troll and a crazy person
18:12 KimLaroux Which is why so many people think I'm a troll
18:13 theBear i wonder, i'm real crazy these days, but i don't THINK i look like a troll
18:13 KimLaroux Why did he leave so early anyways? this was proving to be fun. I still have a bunch of arguments to throw out =(
18:14 KimLaroux theBear: it's all in the way you defend your crazy ideas
18:14 theBear heh, he wasn't doing well in another channel i'm in, and at a guess was doing the same thing in several
18:14 GargantuaSauce was doin' his thing on youtube today too
18:15 KimLaroux ForeverAlone
18:15 theBear he can't be having a good day, coming in here raving out of the blue like that, saw the same kinda comments recently, they were either relayed to me in private or a comment by him on youtube
18:15 theBear re: steppers
18:15 KimLaroux He was stalking you across platforms?
18:16 theBear not quite sure where he gets the idea, and i wasn't making things up, when 'we' make stuff, if there's a problem with slipping steps, or something is critical, we do what it takes to fix it, usually an encoder/feedback setup
18:16 GargantuaSauce it would have been well placed in #reprap maybe
18:16 GargantuaSauce since they all use steppers with no feedback which is a bit infuriating
18:16 theBear nah, i had to police him a bit in electronics recently, and had a few complaints in private, one of them opened my eyes to his rantings on youtube.... i don't tend to hang around anywhere social on the net outside of here
18:17 mLaroux n
18:17 KimLaroux Me either
18:17 KimLaroux Only forums I hang in is Head-fi's DIY section
18:17 theBear maybe, if the x-y moving parts aren't too stiff and the drivers are ok, in theory there's "no load" on something like a reprap
18:17 KimLaroux because the average people there is actually mature
18:17 theBear not to say that i agree with much of the reprap design
18:18 theBear heh, a rare thing these days
18:18 KimLaroux indeed
18:18 KimLaroux And tbh, Freenode isn't that bad compared to all other IRC networks
18:19 theBear nah, most of them went to shit years ago, freenode has only started slipping recently :)
18:19 KimLaroux at least here I don't get 3 PM asking "ASL" for every line I send in public channels
18:20 theBear hehe, that's a point
18:51 ace4016 KimLaroux, it's best to ignore dan...
18:51 ace4016 his opinion never sways
18:51 ace4016 ever.
18:51 ace4016 for his opinion is fact and the way it should always be done
18:51 shuggans Hey all
18:51 ace4016 hola shuggans
18:52 shuggans Talkin bout heysoos?!
18:52 shuggans :P
18:54 ace4016 worse
20:19 eadthem anyone seen kat recently
20:20 Tom_itx sorta
20:25 GuShH and furrywolf?
20:26 Tom_itx no
20:28 eadthem furrywolf is here
21:31 shuggans Hey all
21:44 rue_bed I dont know if I got sleep or if I just laid here for .... 2.5 hours with all the little voices in my head having time to finish saying what they had to say
21:45 DagoRed that's not creepy at all
21:46 rue_bed I'm still tired, but its different, its kinda like _all_ I am is tired
21:47 DagoRed Are you getting sick rue?
21:53 rue_bed no, not that I know of
21:53 rue_bed well, hmm, supper, and play I suppose
21:54 rue_bed check off my ebay item
21:55 rue_bed hmm
21:56 rue_bed wonder where there is room to start a trade school that would sit 80/day
21:56 rue_bed oh, a bunch of the stores in the mall are closing
21:57 DagoRed bad economy?
21:58 rue_bed the electrical trades have min 2 year waiting lists here
21:58 rue_bed have for over 6 years
21:58 Tom_itx there are more empty spots in our malls than i've ever seen
21:58 rue_bed a class of 20 could fit in a typ store space eh?
21:58 rue_bed 4 of those
21:59 rue_bed atleast $1000/head income
21:59 rue_bed I'd do it just to break even
22:00 rue_bed wonder if we have a major restraunt closed out around
22:00 rue_bed that kinda space would work
22:06 shuggans Rue hears the flowers. They are coming to pick him.
22:06 GuShH hes getting high on nature.
22:07 rue_house I think its a money maker
22:07 rue_house shuggans, your back
22:07 rue_house we need to finish from last time
22:07 shuggans yes.
22:08 rue_house you understand how to use a switch to reverse a motor yes?
22:08 shuggans yes
22:08 shuggans Ill be right back
22:08 rue_house you understand that a relay is a magnetically operated switch
22:09 shuggans yes thats always on in one direction till turned "on" n then the other way
22:09 rue_house if the power to it is always on, yes
22:10 rue_house tell me two places we can put a power switch for that
22:12 rue_house do you have a flicker acout you can pot pics to?
22:14 rue_house ok you dissapeared, I'm gonna go make supper
22:32 shuggans rue: have to watch a movie w the fiance. HAVE to. :P
22:32 shuggans ill be back in anhour
22:34 shuggans Fyi: im pretty excited!
22:34 shuggans (for the electronics teachings)
