12:25 AM rifraf: rue_mohr you like fpv, would you like a phone app that can analyse accel data?
12:40 AM rue_shop4: heh, not yet :]
12:40 AM rifraf: why not? i can do gyro as well if you like, to track in time?
12:40 AM rue_shop4: have a goal, really really tryign to stay on track
12:40 AM rifraf: can you buy a phone tomorrow, any 30 one at the grocery store is fine, you need no plan
12:40 AM rue_shop4: I next need to program a CH32 to take serial commands and run two servos
12:40 AM rifraf: ok, me too, well hard for anything to take me off track
12:43 AM rifraf: ok i could change alot, but not the whole layout and size of the dial etc
12:44 AM rifraf: mainly just labels changed
12:44 AM rifraf: the path d stuff too daunting
01:10 AM rifraf: or how to edit path d to adjust scale size etc?
01:10 AM rifraf: not meant to edit all that am i :(
01:15 AM rue_mohr: hmm
01:15 AM rue_mohr: just change the text?
01:16 AM rue_mohr: awe, I wanted to work on my skelatonics suit too
01:16 AM rue_mohr: stupid power convters ate me up
01:20 AM rifraf: planning on trick or treating this year?
01:24 AM rue_mohr: hah
01:24 AM rue_mohr: nobody near my place does that
01:24 AM rue_mohr: was ready for years
01:24 AM rue_mohr: not a soul
01:25 AM rue_mohr: I have a lot of evidence that all the humans are dead you know
01:43 AM rifraf: rue why didn't you make a spinning top yet?
01:44 AM rue_mohr: heh, you didn't catch me sayin why
01:44 AM rifraf: cause i know, i am from the future
01:45 AM rifraf: i am amazed by my own app, because it shows me exactly what i want to see
01:46 AM rifraf: 15 minute csv files rue, at 400 line/sec
01:46 AM rifraf: nice data
01:48 AM rifraf: soon you will be able to design a top and get a dxf exported
02:06 AM rue_mohr: you gonna post that sensor data and I can try to work out why its out?
02:06 AM rue_mohr: just taking a break to get some new music and I'm back to trying to code my servo controller
02:08 AM rifraf: will be testing all my headstocks etc to see what the vibration is like
02:09 AM rifraf: ac servo controller rue?
02:09 AM rue_mohr: oh well, no point in analyzing working data :]
02:09 AM rue_mohr: I'm trying to learn about the ch32 timers so I can operate a hobby servo
02:09 AM rifraf: its to find issues in machines, identify vibration causes
02:10 AM rifraf: ok you want some data, am gonna upload
02:10 AM rue_mohr: but its midnight and I should get to sleep
02:10 AM rue_mohr: I need to wake up early on monday for work
02:10 AM rue_mohr: rifraf, no point if its good data
02:11 AM rue_mohr: if there is a problem, I'll see what I could do to find out why
02:11 AM rue_mohr: which isn't much now
02:11 AM rue_mohr: cause I'm working on other things
02:11 AM rue_mohr: and like I said, I'm trying to focus on them
02:12 AM rifraf: there could be a problem
02:12 AM rifraf: and i know what it may be, but until tom supplies a log i don't know
02:12 AM rue_mohr: ok I can wait
02:12 AM rifraf: focus pocus, trump for potus
02:13 AM rue_mohr: I'm trying to make this servo controller for the project I'm trying to focus and finish
02:13 AM rue_mohr: and I have another personal project that I'm really into and dont have time for
02:13 AM rifraf: focus putus
02:13 AM rue_mohr: and I have paint sprayer customers waiting for sprayers, over a month for one now
02:13 AM rue_mohr: and I have you asking me to help out with this stuff
02:13 AM rue_mohr: I'm overloaded
02:14 AM rifraf: hurry an fulful the orders dude, or you will get a bad name
02:14 AM rue_mohr: and I have a place plugged up with supplies to build things and not getting anything made
02:14 AM rue_mohr: and I want to investiagete the power converters more
02:14 AM rue_mohr: and a skelatonics suit 1/4 made that I could really use a buddy to help out with
02:15 AM rue_mohr: and a big cnc machine that I'd LOVE TO HAVE WORKING, but not for $4000 that would just buy a soluton
02:15 AM rue_mohr: and a truck that needs help
02:15 AM rue_mohr: and I have to build a new house so I have proper elbow room and workshop space
02:16 AM rifraf: ok but at least look at my data quick
02:16 AM rue_mohr: if you feel like your project is just rolling off the top of my pile, thats part of why
02:16 AM rifraf: been workin hard for minutes
02:16 AM rue_mohr: and its midnight and I need to sleep
02:17 AM rue_mohr: everytime I go to do something simple, I have to spend a day fixing stuff first
02:17 AM rue_mohr: and nobody is buying me out of that issue
02:18 AM rifraf: https://desire3d.com/images/public/top1.csv https://desire3d.com/images/public/top2.csv https://desire3d.com/images/public/top3.csv
02:18 AM rifraf: https://desire3d.com/images/public/top4.csv https://desire3d.com/images/public/top5.csv https://desire3d.com/images/public/top6.csv
02:19 AM rifraf: ok tell me wat you think of data and rpm rates etc
02:19 AM rifraf: in my sample rate of and what fft size would you recommend?
02:20 AM rifraf: you can think on it while you sleep sir, no rush
02:22 AM rue_mohr: Single pulse mode can be used to allow the microcontroller to respond to a specific event by causing it to
02:22 AM rue_mohr: generate a pulse after a delay, with the delay and width of the pulse programmable. Placing the OPM bit allows
02:22 AM rue_mohr: the core counter to stop when the next update event UEV is generated
02:30 AM rifraf: you sound like an ai
02:34 AM rifraf: i know you have absorbed rue mr ai creature, just let him be, he was only a loony creator
02:35 AM rifraf: rue_mohr seriously though, that data is perfect data for FFT, cam you please show me what yours can find. i know all 6 files are valid accel readings and should give you some good insight
02:37 AM rue_mohr: csv stands for "comma seperated values" its hard for a csv file to go wrong
02:37 AM rifraf: haveing the data is the best part, cause no matter wat the program shows me now, it can be re analysed later to confirm the findings, i love it.
02:37 AM rifraf: its not the commas dude :/, look between the commas
02:38 AM rue_mohr: it looks like the ch32 timers do have a single pulse mode
02:38 AM rue_mohr: they dont talk about how to software trigger it, but I think I can work it out
02:38 AM rifraf: i think they have a dual mode as well
02:38 AM rue_mohr: I'm not sure if I should use one of the timers as a 'start' and the other as a 'pulse' or if I should just re-purpose the same timer for both
02:39 AM rue_mohr: I could probably also use interrupts for the whole thing
02:39 AM rue_mohr: but I'm not sure what the interrupt latency is
02:39 AM rifraf: both could be tricky, but with nterupts am sure you will be ok
02:40 AM rue_mohr: I think these run at 80MHz, but the io takes longer, so I'm not sure how that works
02:40 AM rue_mohr: if I have the pulses done with the timers, I can have the main loop watch the serial port and parse the packets
02:41 AM rue_mohr: otherwise the pulses would be easy enough to just NOP delay off
02:41 AM rue_mohr: I cant use the tiny13 cause it has no hardware serial
02:41 AM rifraf: Log.e("CSV_Parser", "No Z data found!") help
02:41 AM rue_mohr: I made software serial for it, but I cant do timing and the serial at the same time
02:42 AM rifraf: you just need an android phone
02:42 AM rue_mohr: your not being patient
02:42 AM rifraf: i am mr patient
02:43 AM rue_mohr: Ionly saw my buddy once and I forgot to ask
02:43 AM rue_mohr: it will be ATEAST A WEEK before I see him again
02:43 AM rifraf: grab his phone next time
02:44 AM rifraf: before he smashes it
02:44 AM rue_mohr: and I see my only other LIVING other buddy about 4 times a YEAR, so YOU HAVE TO BE PATIENT
02:44 AM rue_mohr: I think its 4... maybe 2...
02:44 AM rifraf: i only have so much patience, then it runs out
02:44 AM rue_mohr: ad then you throw this all away and move on to something else
02:44 AM rue_mohr: casue you do that...
02:44 AM rifraf: as usual
02:45 AM rifraf: but i need to make some tops
02:45 AM rifraf: so makin the perfect top tester, what you think?
02:45 AM rue_mohr: I want to see a video of your cnc lathe making a top
02:45 AM rifraf: have you tried it yet?
02:47 AM rifraf: what part have you not seen, have posted a bit
02:48 AM rue_mohr: sorry I cant play along today, gnight
02:48 AM rifraf: oh dear, nite nite
02:49 AM rifraf: 3d scanner?
03:07 AM rifraf: still waitin on the levitstor, 5 weeks now
03:07 AM rifraf: should be this =next week though i hope
03:08 AM rifraf: coulda made one in that time, but would not have an app i guess
03:08 AM rifraf: money well spent if it works then
12:18 PM Tom_L: rue_mohr, find some pins that will work?
02:16 PM rue_shop4: controller pins?
02:20 PM Tom_L: the ali pins you posted i assume for the sprayers
02:26 PM rue_mohr: oh I was just keeping the link
02:26 PM rue_mohr: I was using the channel for link dumping cause nobody ever says anything
02:48 PM Tom_L: :)
02:59 PM rue_mohr: is the seattle port usually pretty busy?
03:01 PM Tom_L: no clue
03:01 PM Tom_L: i would imagine so
03:01 PM rue_mohr: - paint sprayers
03:02 PM rue_mohr: - Tom_L apparently the last international ship is doing its dropoff and thats it for international shipments
03:02 PM rue_mohr: wait, thats not a list item, arg
03:03 PM rue_mohr: I need an outdoor list tho
03:03 PM rue_mohr: everything is indoors
03:04 PM rue_mohr: metal casting, welding....
03:04 PM rue_mohr: hmm
03:04 PM rue_mohr: yard cleanup
03:04 PM rue_mohr: but
03:04 PM rue_mohr: its my last day off and I want to get things done that are indoor things
03:07 PM rue_mohr: dig basement
03:08 PM rue_mohr: might have to fall back on just doing anyting to get things done
03:17 PM Tom_L: you got rid of the shed a while back right?
03:24 PM rue_shop4: yup!
03:24 PM rue_shop4: its all on the couch on the deck now :/
03:24 PM rue_shop4: gues I'll want to clear that for camping out on next month or so
03:25 PM rue_shop4: what do I do with 22 working lcd monitors?
03:28 PM Tom_L: have an lcd front yard sale
04:39 PM rue_shop4: :], yea I shoudl gather up a few things
04:51 PM rue_mohr: ok, I did some yard work, planted two trees and filled some holes
04:51 PM rue_mohr: and dug out the basement a bit
04:52 PM rue_mohr: Tom_L, you familiar with a box drag?
05:06 PM Tom_L: in regard to what?
05:07 PM Tom_L: leveling dirt?
05:20 PM rue_mohr: planning to make an automated winch to drag soil out from under the house
06:01 PM Tom_L: how much room do you have under there now?
06:05 PM rue_shop4: none
06:05 PM rue_shop4: space isn't relative, its negative.
06:06 PM Tom_L: why are you digging if you're planning to rebuild?
06:06 PM rue_shop4: get the septic tank out from under the house
06:06 PM rue_shop4: first part of excatavitng for the foundation of the new place
06:06 PM Tom_L: gonna move it?
06:06 PM rue_shop4: nope
06:07 PM rue_shop4: gonna consume it with the new house
06:07 PM rue_shop4: no move out
06:07 PM rue_shop4: just move things around a bit as the new place is built
06:08 PM Tom_L: i did
06:08 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/temp/house/1.jpg
06:08 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/temp/house/2.jpg
06:08 PM rue_shop4: oh, I missed something on the welding list, the trike has a broken joint
06:08 PM rue_shop4: Iknow
06:08 PM rue_shop4: thats the plan - after the septic tank is out -
06:08 PM Tom_L: did it all but the hole and the concrete
06:09 PM rue_shop4: so I have an interseting problem
06:09 PM Tom_L: aside from clay what?
06:09 PM rue_shop4: when I built the shop I didn't know the hosue was crookid on the lot
06:09 PM Tom_L: so?
06:09 PM rue_shop4: so, I lined up the shop with the house
06:09 PM Tom_L: leave it crooked
06:09 PM rue_shop4: and its not just a bit crookid, its REALLY crookid
06:10 PM Tom_L: who cares?
06:10 PM rue_shop4: mmm sort
06:10 PM rue_shop4: a
06:12 PM rue_shop4: so, I looked up servo control code for a ch32 on github
06:12 PM rue_shop4: the hit I found uses a nop delay in an interrupt
06:12 PM rue_shop4: really people?
06:16 PM Tom_L: knew some ppl that hand dug a basement under their house but didn't gain all that much space since they left probably 4' from the outter walls untouched
06:16 PM Tom_L: seemed like alot of manual labor for the gain
06:18 PM Tom_L: when they did mine, they put drain pipe all around the perimeter
06:30 PM rue_shop4: - cover for tx module
06:31 PM rue_shop4: yup
06:31 PM rue_shop4: I probably have to excavate out +4' around the house and drop in a lockblock wall to keep the water back
07:02 PM rue_shop4: Tom_L, I must have badly overheaded lots of the plastic for those casting attempts, the ones I come across are crumbling
07:50 PM Tom_L: i thought you said the mold was too cold
07:51 PM Tom_L: rue_shop4, do they do basements in your neck of the woods?
08:54 PM rue_mohr: yup
