00:04 rue_house do you know what a keyword to find a youtube video for the thing where they explode propane in tubes to play music
00:08 katsmeow-afk http://www.youtube.com/watch?v=f3h4DXOVSzE
00:11 katsmeow-afk http://www.youtube.com/watch?v=VB02ii6DZ1Y
00:14 rue_house no
00:14 rue_house not a rubens tube
00:14 rue_house tehre is one that is 20+ feet tubes, lots of them, they ignight the propane in bursts
00:15 rue_house big tubes , bursts
00:15 katsmeow-afk i dunno
00:17 Tom_L mmm
00:17 Tom_L so far so good
00:17 rue_house tom do you know?
00:17 Tom_itx what do i know?
00:18 rue_house <rue_house> tehre is one that is 20+ feet tubes, lots of them, they ignight the propane in bursts
00:18 rue_house do you know what a keyword to find a youtube video for the thing where they explode propane in tubes to play music
00:19 rue_house lengh tuned resonance
00:19 katsmeow-afk http://www.youtube.com/watch?v=m-IzF_ti8RU
00:19 rue_house no
00:20 rue_house 40 foot high tubes that they ignight bursts of propane in to 'slap' them
00:22 katsmeow-afk http://www.youtube.com/watch?v=KdiQU6MbNnA
00:22 katsmeow-afk ignite
00:22 rue_house those are burned, not ignighted
00:22 rue_house not 40' high
00:22 rue_house (feet)
00:22 katsmeow-afk http://www.youtube.com/watch?v=PnZsLgn188o
00:23 rue_house think of 50 40' spud cannons made of 8" steel tube
00:23 rue_house thats people playing beside big pipes
00:23 rue_house but the pipes aren't big enough
00:24 katsmeow-afk http://www.youtube.com/watch?v=rx8JQr6NwXA
00:25 katsmeow-afk http://www.youtube.com/watch?v=clUQMbZVwi0
00:26 katsmeow-afk so far my problem with making small compact high efficency propane heater is making it NOT sing
00:27 katsmeow-afk http://www.youtube.com/watch?v=J1vF-wil1_I
00:27 rue_house fist isn't burst ignition
00:27 rue_house second isn't burst ignition
00:28 tsmeow-afk goes to a corner and curls up into a lil
00:28 rue_house thirsd isn't burst or electronic ignition
00:28 rue_house none of them are 40' 8" pipes
00:28 rue_house your finding links like I am
00:28 rue_house all roughly fit the desctiption and none are right
00:29 rue_house grrr
00:29 rue_house http://www.smh.com.au/ftimages/2005/01/27/1106415708242.html
00:30 rue_house this large hot pipe organ is close, it might even be an early version of what I'm looking for
00:30 rue_house but there aren't enough pipes and its not playing the music I remmeber
00:31 rue_house http://www.youtube.com/watch?v=3oZblA85vZc <-- not that either
00:31 tsmeow-afk does not
00:34 rue_house zhanx,
00:34 rue_house Tom_itx, !?!
00:39 rue_house its bugging me now
00:40 rue_house how many machines like the "large hot pipe organ" could there be!?
00:46 katsmeow-afk "percussion maintenance" = "hit it with a large hammer" ?
00:48 rue_house I think it is the "large hot pipe organ" but there must only be one good song/video and I can find it
00:48 rue_house cant
00:49 katsmeow-afk cant = lean ; can't = cannot
00:49 katsmeow-afk just fyi :-)
00:49 rue_house t disn't work right
00:52 katsmeow-afk That stops a smart AI from doing things such as sending hidden Morse code messages to human sympathizers by manipulating a computer's cooling fans.
00:53 rue_house DAMNIT I CANT FIND ID
00:53 rue_house ARRRRRRRRRRRRRRRRRRRRRRRRRRRRG
00:53 rue_house its a cross between the blue man group and the large hot pipe organ
00:53 rue_house cant find it
00:54 rue_house they play music in tuned tunes by ignighting propane explosions, its pretty cool
00:54 rue_house ~2003 or so
01:18 rue_house http://www.marginallyclever.com/2012/02/linear-interpolation-vs-trapezoid-motioninterpolation/
01:18 rue_house how can I expand the idea to make it so you can define any velocity profiel you want?
01:19 rue_house OOOOOOOOOooooooooooooo I did avr code for controntrolling steppers via a serial interface
01:20 rue_house oh yea I remember this library
01:20 rue_house hmmmmmm
01:20 rue_house the controller pings you back when the step timer is finished
01:23 rue_house void SimotaniouslyLinearlyInterpolateMultiAxis(axies_t * this) { aha its in "interlin.c"
01:24 Triffid_Hunter rue_bed: http://www.eetimes.com/design/embedded/4006438/Generate-stepper-motor-speed-profiles-in-real-time
01:25 rue_house I made my interpolator library so a seperate velocity profiler library could be used with it
01:25 rue_house so I just need somehting to work out delay rates for a velocity profile
01:26 rue_house I dont need to worry about synching axies, my code already does that
01:28 rue_house logistics look ok, but looks pretty impractical for real world application
01:29 rue_house but its got me thinking
01:30 rue_house hmm I wonder how fast you do a step if your only doing one step
01:30 rue_house I suppose you have to look at how long you were on the last step for
01:30 rue_house huh
01:39 rue_house hmm
01:40 rue_house I guess you can get all mathy about it and look at it in terms of real acceration in degrees/second
01:40 rue_house know how many degrees is in each step and do the math
01:40 rue_house or, like me, you just know hte max step rate you want to run at and ramp up/down to/from that
01:41 katsmeow-afk xactly, because it will depend on binding bearings, leg inertia and momentum, etc
01:43 katsmeow-afk hmm,, make it truely learnng, set a position feedback to the brains, and let it pick it's own accel.decel curve based on power needs and speed errors and such
01:44 katsmeow-afk pick up the leg veeeewwwwyyy slowwllyy,, then stab it down at 10x gravity to spear a bug
01:45 katsmeow-afk use the 2 hind legs bery carefully to pick up and aple and bring it to you
01:45 tsmeow-afk needs to bein
01:45 katsmeow-afk gnites
01:46 rue_house gnight
01:47 rue_house sync() is a callback from the interpolator
01:47 rue_house hmm
01:48 rue_house it could have the axis registered.... no
01:52 rue_house hmm, there is no progress tracking means in the interpolator
01:52 rue_house but, you woulnd't want that anyhow
01:52 rue_house if your following a nonlinear path, you dont want the linear segmensts you make it out of to end in a 0 velocity anyhow
01:52 rue_house hmm
01:53 rue_house so the question is, how do you know when your stopping and when your last step is part of a larger motion path
01:53 rue_house well you cant do it from the data you have at this level
01:53 rue_house no, but I dont have any other levels up right now
01:54 rue_house then you cant come up with anything generic for that
01:54 rue_house so, back to square 1, how do I come up with a velocity profiler
01:54 rue_house maybe you should interpolate the velocities
01:54 rue_house ah, ok, how does that work
01:55 rue_house when you set the motion target you also set a target velocity, and the library ramps the velocity up/down at up to the max accel level to get it there
01:55 rue_house so you set a target position and velocity
01:56 rue_house yes, for your simple paths you always set the target velocity to 0
01:56 rue_house how would it ramp up and down to do a simple line if you start at 0 velocity and finish at 0 velocity
01:56 rue_house thats a good question
01:57 rue_house and how do you break up a velocity profile on a complex motion path
01:58 rue_house each axis must conform to a min/max acceleration
01:58 rue_house right
01:58 rue_house if you start at 0 and finish at 0 (velocity) then you must apply a min velocity in the middle
01:58 rue_house what if its a long line and I want to hit a max velocity in the middle
01:58 rue_house ok
01:59 rue_house well
01:59 rue_house hmm you need to apply a min/max acceleration, and a max velocity, it would use these paramiters for every path to get from the position/velocity it has to the position/velocity its targeting
02:00 rue_house that would be a problem if I want a constant velocity
02:00 rue_house but you dont want a constant velocity
02:00 rue_house I dont?
02:00 rue_house you want a min/max acceleration
02:01 rue_house let me think a sec on that
02:01 rue_house k
02:01 rue_house say I am doing a circle, in line segments
02:01 rue_house k
02:02 rue_house I go into each segment at a particular velocity
02:02 rue_house and I want to leave each segment (less the last one, or few, or soemthing) at a particular velocity
02:03 rue_house you want to set the max velocity and the max acceleration
02:03 rue_house hmm
02:03 rue_house cause you dont care about your velocity, you care about your acceleration
02:03 rue_house yes, and the velocity is just a limit
02:04 rue_house wait, then how do we stop at the end of the circle
02:04 rue_house circles dont have ends
02:04 rue_house haha
02:04 rue_house yea thats a problem
02:05 rue_house you need to break up the velocity profile based on what part of the circle your doing, the local code only knows about the line segment being done of the circle
02:05 rue_house the problem is knowing when your comming to a stop
02:06 rue_house yea, but beforehand
02:06 rue_house just stop looking at the path from the perspecitve of the line interpolator
02:06 rue_house yes we need to look at it from the pov of the superceeding path controller
02:07 Triffid_Hunter rue_house: so you need to queue a series of moves, and back-propagate a max speed from the end of the queue
02:07 rue_house I like that
02:07 Triffid_Hunter such that if no more moves appear in the queue, you can come to a stop at the end while obeying accel limits, but if more moves show up then you can increase the max speed for previous moves
02:07 rue_house yea that solves the time problem
02:08 Triffid_Hunter reprap firmwares have been hashing this stuff out for ages ;)
02:08 rue_house and if an axis needs to come to a complete stop, you can work that out too
02:09 rue_house the queue dosn't cuase a delay, cause the mechanics are so slow anyhow
02:09 Triffid_Hunter well sure, that becomes an intrinsic because you always organise your speeds so you can be completely stopped by the end of the queue
02:09 rue_house or by a stop in any one axis
02:09 Triffid_Hunter the trick now is that your queue has to be long enough that you don't slow down unnecessarily when there are lots of short segments ;)
02:09 rue_house well you just accelerate the axis to a stop, you dont have to stop them all
02:10 rue_house hmm the system would kinda need to know how long each queued motion is
02:10 rue_house yea so it can know how much de-accel it might have to do
02:11 rue_house by the path length in the queue you can work out the max safe velocity based on the max de-accel
02:11 Triffid_Hunter that's easy with reprap firmwares, we feed them a sequence of points in XYZ with a max speed for each move
02:11 Triffid_Hunter if you're organising your data some other way it could be tricky
02:12 rue_house this is a generic library I'm on
02:12 rue_house right now it passes off the delay between motion steps
02:12 rue_house so the code that handles it can do anything it wants
02:12 rue_house which effectivly controls the step speed
02:13 rue_house its pc side code
02:14 rue_house the other thing thats nice about the queue is that you can push random paths into it and it performs the same
02:14 Triffid_Hunter yep
02:15 rue_house there will be a path length were at maximum velocity a stop at max de-accel is still possable
02:15 rue_house there will be a relation between path length and max velocity at which you can stop the path at 0 speed
02:16 rue_house therefore you can make a queue that is full as long as there is enough path length in it to come to a full stop at max velocity, otherwise it automatically slows down
02:17 rue_house I see more callbacks
02:18 rue_house so I need to write a position queue for the interpolator
02:18 rue_house and that will tie into the velocity profiler
02:20 rue_house this prolly wont be hard, right now you operate the interpolator by setting all the target positons and calling the interpolator
02:20 rue_house its passed as basically an array of axis structs
02:21 rue_house each queued item needs to have the length of its major axis measured
02:22 rue_house hey what happends if the controlling axis changes between queued positions?
02:22 rue_house hmm that kinda sounds like instantanious velocity changes
02:23 rue_house so then we need to look at this on a per-axis basis
02:24 rue_house aha
02:24 rue_house thats the problem, when one axis is comming to a stop and another isstarting up
02:24 rue_house while another is running steady
02:25 rue_house yea, that screws up the way the interpolator distributes steps
02:27 rue_house yea, the fact the interpolator applies the max velocity to the axis that moves the farthest and scales back the other ones with no regard to the previous or next velocities on that axis
11:54 reesk92 hiya everyone
12:12 dunz0r Hello reesk92/
12:13 reesk92 heya
12:13 reesk92 how are you dunz0r
12:13 dunz0r Good.
12:14 reesk92 awesome
12:14 dunz0r Can't wait for this night to be over. I want to get home and assemble my sumobot completely
12:14 reesk92 been up to any fun projects latley
12:14 reesk92 cool
12:14 reesk92 what platform does it use for the micro controller
12:15 dunz0r Atmega 2560
12:16 dunz0r A bit overkill probably, but I need 20 pins and ~6 interrupts-pins
12:16 dunz0r And I happened to have a board for another project laying around
12:17 reesk92 im using the 2560
12:17 reesk92 its the mega bored right
12:18 reesk92 the one with the big block of digital pins at the bottom
12:19 reesk92 smiles
12:21 rue_house hmm where is that diagram for coding my storage scope
12:22 reesk92 whats a coding storage scope
12:22 rue_house its a misunderstanding
12:22 rue_house do you know what a storage scope is?
12:22 rue_house I need to write some microcontroller code for one
12:23 reesk92 yeah
12:23 reesk92 well i sorta do
12:24 reesk92 its a ocillscope that can capture wave forms right?
12:24 reesk92 rather than viewing the live wave
12:34 reesk92 right?
13:52 rue_house http://eds.dyndns.org/~ircjunk/robots/arm5/p1030872.jpg
13:52 rue_house http://eds.dyndns.org/~ircjunk/robots/arm5/p1030873.jpg
13:52 rue_house reesk92, yes
13:53 rue_house cause mechanical movements are too slow to monitor for overshoot without something to store the movement
13:55 Steffanx You build things like that rue_house ?
13:57 rue_house :) yea
13:57 rue_house http://eds.dyndns.org/~ircjunk/robots/robot_family2.jpg
14:00 Steffanx I like the large arm
14:07 rue_house mmm
14:15 Steffanx mmmm… cdonalds?
14:15 rue_house no
14:15 rue_house yum loarge robot arms
14:16 rue_house ...
14:18 reesk92 i like the personal servers of electronics hobbysits there info gold mines
14:20 Tom_itx so you can hack them?
14:20 Steffanx Most of them use html without database
14:20 Steffanx So that makes it a little harder
14:20 reesk92 no i dont mean hack them
14:20 Steffanx Maybe the old apache can help you
14:21 reesk92 i mean you can browse them and they have a lot of info thats usefull and interesting to read
14:21 reesk92 get ideas
14:21 reesk92 see projects
14:21 reesk92 like this
14:21 reesk92 http://eds.dyndns.org/~ircjunk/robots/coffeebot/dscn4451.jpg
14:21 reesk92 its one of his robots
14:21 Tom_itx or this? http://tom-itx.dyndns.org:81/~webpage/
14:21 Steffanx mine is better
14:21 Tom_itx sure is
14:21 Steffanx http://naffets.nl :P
14:22 reesk92 i should document my first robot onto my webserver for epople to see
14:22 Steffanx Uh.. how THAT can give an php error :S
14:22 Tom_itx nothing there sir
14:23 reesk92 that seems easy enough to fix
14:23 Steffanx Tom_itx .. i know
14:23 reesk92 youve either mispelt the function or the function dosent exist because it was never made
14:24 reesk92 or the php file the function is on is not linked right
14:24 reesk92 but you probably already know this
14:24 Steffanx Yeah, but that function shouldn't be there
14:24 Steffanx Gone
14:24 reesk92 hmm strange
14:24 Steffanx probably some test i did once
14:24 reesk92 that is a verry informative website
14:24 reesk92 i learnt alot
14:25 Steffanx ty
14:25 reesk92 i learnt theres nothing there at all
14:25 reesk92 if i was in the mood id scan for sub dirs
14:25 reesk92 but im feeling lazy
14:26 Steffanx No public sub_dir anyway
14:26 Steffanx sub dirs
14:26 reesk92 spoil sport
14:26 Steffanx i mean.. open dirs
14:26 reesk92 get some sexy index of goodness going
14:29 reesk92 go on show me some nauyght directory listing porn
14:30 Steffanx uhu, i store that on a share hosting ofcourse
14:30 Steffanx shared
14:31 reesk92 how much that cost
14:40 Steffanx Not more than Tom_itx's energy bill
14:40 Steffanx For his private server
14:41 reesk92 mine costs me a couple pence each day
14:41 reesk92 and im paying the energy bill anyway i might as well use it
15:06 reesk92 i may post pictures of my first robot im building as i make progress if anyones interested
15:40 reesk92 no takers then :)
16:06 dunz0r reesk92: I wouldn't mind looking at some pics.
16:07 dunz0r reesk92: You can use something like letsmakerobots.com for posting pictures and what not.
16:17 reesk92 i have a server with dns on it
16:17 reesk92 so posting isnt a problem
16:27 dunz0r reesk92: Come on. Show me yours and I'll show you mine :)
16:32 rue_house reesk92, yea, use lexan, not plexiglass
16:32 rue_house plexiglass fractures
16:32 dunz0r From Stockholm Robot Challenge 2011; http://hax0r.se/files/img/robot/SRC_2011/ . Here's a picture of the robot: http://hax0r.se/files/img/robot/SRC_2011/_DSC6073.JPG
16:32 rue_house and making tracks out of bike chain is a trick I havn't worked out yet
16:45 iR0b0t1 wat does rabat do?
16:46 iR0b0t1 (you could also rehost resized pictures :) )
16:49 dunz0r iR0b0t1: I could also host resized picturs, but then I'd have to resize them.
16:49 dunz0r iR0b0t1: Line follower with PD-control
16:50 iR0b0t1 Well, if you're going to be showing people routinely, look into making a script using imagemagik or something.
16:50 iR0b0t1 Also, cool
16:50 iR0b0t1 Why did you choose two treads on the front?
16:51 dunz0r iR0b0t1: It's on the back, and how else would it turn?:)
16:52 iR0b0t1 ._.
16:52 iR0b0t1 lol
16:52 dunz0r I could've gone with something other than differential steering ofc, but I like differential steering
16:52 iR0b0t1 I mean, as opposed to wheels or similar?
16:53 dunz0r I didn't have any good wheels, made it really fast. Wheels would probably have worked out better.
16:53 rue_house quite the course,
16:53 rue_house I did like the VRC and made a modular one
16:54 dunz0r I tried it with tracks sort of though: http://hax0r.se/files/img/robot/_DSC5861.JPG http://hax0r.se/files/img/robot/_DSC5862.JPG
16:54 dunz0r But that didn't work at all.
16:54 rue_house crazy big images, dont need that much detail really.
16:54 dunz0r The wheels I "made" had to little traction and the steering thing just got in the way.
16:55 rue_house yea, you want a castor for that
16:55 dunz0r rue_house: Yeah. You probably are right. 14MP is a bit much.
16:55 rue_house I can count the specks of dirt on your gears
17:01 reesk92 show you my what
17:02 dunz0r reesk92: Robots of course.
17:04 rue_house ok so
17:05 rue_house the serial interrupt sets the sample counter to its max value
17:05 rue_house the timer starts an adc conversion
17:05 rue_house the adc finish interrupt aborts if the sample counter is 0, otherwise it saves the sample in the buffer
17:26 thylane http://singularityhub.com/2012/02/22/starting-march-1st-a-red-license-plate-in-nevada-means-the-driver-is-a-robot/
17:29 rue_house haha
17:29 rue_house do robots get pulled over for talkingon the phone while driving?
17:35 moriarty rue_house, not to mention lewd behaviour in public, being clothless and all
17:36 katsmeow-afk <car> just as i was downloading data about this road, the construction crew moved the cones, honest!
17:54 rue_house sweet, when you short the mic on the headset of the cell phone it picks up/hangs up the call
18:45 rue_shop I'm gonna make a wired speakerphone for the cell for the car
18:46 rue_shop that way it isn't possable for my call to be stolen from me by bluetooth when I get too close to the car
18:46 rue_shop !time
18:46 tobbor My watch says its 16:39 Sun Mar 04 2012
18:46 rue_shop SolarNRG, hows the project?
18:46 SolarNRG Can I use windscreen wiper motors AND rotory encoders for a CNC milling machine project?
18:47 SolarNRG I assembled x axis gearbox mk 2
18:47 rue_shop yes
18:47 SolarNRG mk 3 even
18:47 SolarNRG Isn't that going to be LOADS cheaper than stepper motors?
18:47 rue_shop did they line up ok?
18:47 rue_shop SolarNRG, its more complex
18:47 SolarNRG I wired up my stepper motor to my gear
18:47 SolarNRG I'll make a pic hold on
18:47 SolarNRG It's easier to explain what I've done that way
18:47 SolarNRG BRB
18:47 rue_shop and driving any auto motor is hard cause of how much current they pull
18:51 SolarNRG http://i.imgur.com/zItpU.jpg
18:51 SolarNRG Here's a view of the inside of my NEW gearbox
18:51 SolarNRG Only when I plugged it all in it just whizzed a bit and no motion
18:51 SolarNRG hmm
18:51 SolarNRG http://i.imgur.com/fzxvS.jpg
18:51 SolarNRG Here's another shot
18:51 SolarNRG http://i.imgur.com/uF9LF.jpg
18:52 SolarNRG I'm hoping that the big turntable will turn
18:52 SolarNRG And I can mount my y axis gearbox on that
18:52 SolarNRG And it will be MUCH stronger than the old broom handle model
18:52 SolarNRG Because the turntable is bolted into the steel gear with 4x 8mm bolts
18:53 rue_shop :) I think your getting closer
18:53 rue_shop its my oppinion that the wood will stuff you up, I recommend metal :)
18:54 SolarNRG Can you build me a cnc milling machine maybe only a foot by a foot?
18:54 SolarNRG that can mill aluminium
18:54 rue_shop so far all my attempts result in 6x12
18:54 rue_shop :)
18:54 rue_shop wow, did you make your own bearing?
18:55 SolarNRG yes sr
18:55 SolarNRG dremel trio
18:55 rue_shop heh cool
18:55 rue_shop can I show you a way that might be easier?
18:55 SolarNRG I had to stack the gearbox upside down to put the top bearing on
18:55 rue_shop if you have to do again
18:55 SolarNRG I got the BBs from the bike shop dirt cheap
18:55 SolarNRG Sure
18:56 rue_shop hehe
18:56 rue_shop pls wait
18:58 rue_shop from http://eds.dyndns.org/~ircjunk/robots/rovbot/dscn0664.jpg to http://eds.dyndns.org/~ircjunk/robots/rovbot/dscn0683.jpg
18:58 rue_shop sorry, no page for that one
19:00 SolarNRG OK, a crusty old bike upside down supported by a ladder
19:00 rue_shop if you go thru every image between those two
19:00 rue_shop its me building a thrust bearing
19:04 SolarNRG I see
19:04 SolarNRG Its very similar to mine
19:05 SolarNRG Any ideas why the motor won't turn?
19:11 SolarNRG Am I best off going down the large stepper motor route?
19:14 rue_house 38400
19:14 rue_house N81
19:15 Tom_itx so, i wanna know what we did Saturday?
19:17 SolarNRG I got drunk
19:20 rue_shop you got some more baords done!?
19:20 rue_shop whats 38400/16
19:22 SolarNRG 9600?
19:22 rue_shop @#$!$# there is a 14.7456Mhz crystal on this silly thing
19:23 rue_shop switch to divider 7
19:23 rue_shop 115200
19:24 rue_shop errors will come in so fast you will never know whats going on
19:26 rue_shop OH YEA
19:26 rue_shop you get the stop bit count right and an avr really can do 115200
19:27 rue_shop ok
19:27 rue_shop thats gonna make the sample timer more fun
19:28 Tom_itx so rue_shop
19:28 Tom_itx that quad code you wrote using pin interrupts
19:28 rue_shop yea?
19:28 Tom_itx you could only get one per port
19:28 rue_shop no
19:28 Tom_itx since the interrupt would interfere with the other encoder
19:28 rue_shop it was limited by the number of pin change interrupts on the controller
19:28 rue_shop no
19:28 Tom_itx and you wouldn't know which one did it
19:29 rue_shop any interrupt for all encoders can update all encoders
19:29 rue_shop dosn't matter
19:29 rue_shop the state machine is fine with a delta position of 0
19:30 Tom_itx so rue_shop, what did we do saturday?
19:30 rue_shop the fastest taredown of a xerox copier I think I'v ever seen
19:31 rue_shop and the distracted kid played with the scope while the focused kid worked on position storage for the robot arm
19:31 Tom_itx haha
19:32 rue_shop I think the whole thing was in components within an hour
19:32 Tom_itx still useable?
19:33 rue_shop yup
19:33 rue_shop a few stripped screws and a bent peice of shielding
19:33 rue_shop well
19:33 rue_shop and one slightly overstripped motor
19:33 rue_shop I can revive that tho
19:34 Tom_itx got most of my office moved
19:34 Tom_itx not unpacked yet
19:34 rue_shop different building?
19:36 rue_shop the avr is saying "UUUUUUUU" but it wont tell me what I did
19:36 Tom_itx no
19:36 Tom_itx i moved upstairs
19:36 rue_shop ah
19:36 rue_shop out of the flood zone?
19:37 Tom_itx i liked it there
19:37 rue_shop into the tornado zone
19:37 Tom_itx yep
19:37 rue_shop the inlaw is taking it over?
19:37 Tom_itx oh hell no
19:37 rue_shop your filling it with dirt and making it a crawlspace again?
19:38 rue_shop there are 3 elements to my program
19:38 rue_shop the serial port, the adc, and the timer
19:40 rue_shop I have the basic serial working
19:40 Tom_itx so what do the 3 elements do?
19:40 Tom_itx serial should be easy
19:40 Tom_itx we've written that quite a few times
19:40 rue_shop the serial sets the buffer up for the adc, the timer triggers the adc
19:41 rue_shop the adc fills a buffer and its sent out the serial port
19:41 rue_shop ah, I'll set up a buffer, and have the avr push back 344 bytes of data on request
19:46 Tom_itx oh crap, i gotta get an order ready
20:10 rue_shop ok there
20:10 rue_shop that should do for now
20:10 rue_shop every time you ask for a buffer it gives a buffer filled with a constant thats 1 more up from the last buffer
20:10 rue_shop with that I can test the gui code
20:47 katsmeow-afk i never thought i'd see a plant on Braxeninsel island, but thanks to the internets, i can
20:47 Tom_itx is it barren?
20:47 katsmeow-afk i didn't inspect it that closely, but it's a plant, so prolly not
20:50 katsmeow-afk it's a very small island in the Eibsee Lake
20:50 Tom_itx hmm

20:55 katsmeow-afk Steinbichl consists actually of larger rock in moose with approximately 400 m 2, sow smaller 7 meters south the southeast point with 10 m 2.

22:57 rue_house so I been trying to make some tools to make what I do easier
