12:01 AM rue_mohr: huh, I think their bricked
12:16 AM rifraf: you will just be like a gen z or watever and just assume it should be so, not understanding the weeks it took to get there
12:16 AM rifraf: or years actually now
12:16 AM * rifraf has an extra tequila shot for that fact
12:16 AM rue_mohr: arg
12:16 AM rue_mohr: they both have completely dead batteries, and wont charge, I need to manaully charge them up
12:16 AM rue_mohr: but the newer? one of them wont open
12:16 AM rifraf: dude i thought you were high tech
12:17 AM rue_mohr: poly battery, need to be careful
12:18 AM rifraf: now you sound like a scammer
12:19 AM rue_mohr: I dont have any tape in my room????
12:19 AM rifraf: am sure you have some beta or vhs
12:20 AM rifraf: maybe some 4 track from the 70s'
12:21 AM rue_mohr: 8 track was a fad
12:21 AM rifraf: rue_mohr what kinda spinning tops do you have already?
12:22 AM rue_mohr: oh
12:22 AM rue_mohr: date on the battery
12:22 AM rue_mohr: 2017
12:22 AM rue_mohr: guess it wont work then
12:23 AM rue_mohr: I'll quit before I start a flipping fire
12:24 AM rue_mohr: well rifraf, cant you just recompile it for an older version>?
12:24 AM rue_mohr: I mean the difference is probably only header files anyhow
12:26 AM rue_mohr: geez, I have dead phones everywhere
12:26 AM rue_mohr: just tripped across another blackberry I was using as an amp3 player
12:27 AM rue_mohr: rifraf, in the meantime, why dont you show me a vid of the app working on your phone, the way you intended it to work?
12:31 AM rue_mohr: huh, their not $1000 anymore
12:31 AM rue_mohr: $115 for a "chatr"
12:31 AM rue_mohr: 32G
12:31 AM rue_mohr: as its not apple, I presume its android
12:32 AM rue_mohr: heh, I'v had the mouse I'm using longer than I'v known you rif :]
12:32 AM rue_mohr: bought it in 1999
12:33 AM rue_mohr: oof, that one is $1004
12:33 AM rifraf: ok will maKE a vid soon
12:33 AM rue_mohr: the google one is $796
12:35 AM rue_mohr: I wonder what their like on ali...
12:36 AM rue_mohr: $919
12:36 AM rue_mohr: oh $78
12:36 AM rue_mohr: https://vi.aliexpress.com/item/1005007096221203.html
12:37 AM rifraf: cannot get that deal here, jump on it
12:38 AM rue_mohr: https://vi.aliexpress.com/item/1005006069317046.html
12:38 AM rue_mohr: $44
12:39 AM rue_mohr: why would I want one tho?
12:39 AM rue_mohr: pay $100/mo for a plan?
12:40 AM rue_mohr: https://vi.aliexpress.com/item/1005008186666070.html OMG I think its the smartphone Amy keeps accidently swallowing
12:40 AM rifraf: need no plan to yest app
12:41 AM rifraf: test^
12:41 AM rue_mohr: huh, I wonder if the $40 ones are garbage
12:42 AM rue_mohr: I suppose their candy for people who break them every day
12:42 AM rue_mohr: I swear I seen people break their phones like 3 days after buying them
12:42 AM rue_mohr: at the old job I had an otterbox for the phone and it was fine like 7 years later
12:44 AM rue_mohr: kept the updates turned off, so it was fine, but eventually the lack of ability to get apps and the battery life were blockers
12:44 AM rue_mohr: the replacement they got me was a mess
12:45 AM rue_mohr: I wonder if their still throwing out the whole set of crew phones every 2 years
12:45 AM rue_mohr: that would be 22 phones rif!
12:45 AM rue_mohr: 2 years old!
12:52 AM rue_mohr: rifraf, how do you describe "tech-debt" ?
12:53 AM rifraf: never tried
12:53 AM rue_mohr: asking chatgpt...
12:53 AM rue_mohr: "Technical debt is the concept of taking shortcuts in software development to deliver faster results—knowing that those shortcuts will need to be revisited and fixed later. It's like borrowing time from the future: you get to move quickly now, but you’ll “pay interest” later in the form of extra work, bugs, reduced performance, or difficulty adding new features."
12:54 AM rue_mohr: but
12:54 AM rifraf: well i am npt doing that
12:54 AM rifraf: this app is nearly right
12:54 AM rifraf: but i want you input
12:55 AM rue_mohr: what it fails to say, is that people are building on tech-debt... so the stuff their are borrowing on is built on unpaid tech-debt
12:55 AM rue_mohr: oh I'm not saying you were, I'm reffering to disposable tech
12:56 AM rue_mohr: and a "run" of disposable tech that depends on the most recent disposable tech
12:56 AM rue_mohr: and you can never go back
12:56 AM rue_mohr: you cant build the tech from scratch
12:56 AM rue_mohr: it depends on the version of xxx software made yesterday
01:11 AM rue_mohr: and ONLY that version
01:11 AM rifraf: am doin something a biy new here
01:11 AM rue_mohr: on twitter I'm watching people assemble old computers with old versions of windows to be able to compile programs 'of the day'
01:11 AM rue_mohr: and I kinda laugh, cause I see it all over
01:11 AM rue_mohr: ESPECIALLY with microcontrollers
01:11 AM rifraf: how many phone apps interact with a physical object anyone can buy and most people have
01:11 AM rue_mohr: I have a whole bunch of CPLD and FPGA that can ONLY be used with the version of software they made *then*
01:11 AM rue_mohr: rifraf, :] esp things that dont support wifi and bluetooth :]
01:11 AM rifraf: rue test my app please
01:11 AM rue_mohr: sure, sounds like I need to buy a phone to do it tho
01:11 AM rifraf: is basic accel that any phone has
01:11 AM rifraf: even only needs Z axis
01:11 AM rue_mohr: you gonna send me a vid in the meantime?
01:11 AM rue_mohr: and I'll machine a top and buy a phone
01:11 AM rifraf: yep
01:18 AM rue_mohr: polprog, what controller is in it?
01:20 AM rifraf: an 8051 from 1985
01:21 AM rue_mohr: polprog, reprogrammed a radio of some kind
01:21 AM rue_mohr: he was up till 3am working on it
01:21 AM rue_mohr: didn't recognize the programmer
01:23 AM rue_mohr: maybe its a jtag programmer
01:30 AM rue_mohr: ok, there were 3 programming projects
01:30 AM rue_mohr: the esp8266 serial link
01:31 AM rue_mohr: ugh, I need to get the sprayers made
01:31 AM rue_mohr: you know, I do a lot better job of this at work
01:32 AM rue_mohr: 5 tasks, choose one and kill
01:32 AM rue_mohr: even tho I get bounced around
01:34 AM rue_mohr: I was interrupted from some plug wiring by a room plug test, then went back to it to get pulled away to do alarm wiring for a fridge, then had to do a circuit find and set up some work for a fellow covering for me during my time off
01:35 AM rue_mohr: I have a billion things to get done at home and I never seem to get enough done
01:35 AM rue_mohr: I still need to finish fixing the coffeemaker
01:36 AM rue_mohr: if I can get that done I should never need to fix it again
01:36 AM rue_mohr: commercial machine this time
01:36 AM rue_mohr: Rue, talk to me would ya?
01:36 AM rue_mohr: hi
01:37 AM rue_mohr: there is that greenhouse project too
01:37 AM rue_mohr: ugh, I forgot about that one
01:38 AM rue_mohr: and the software project your looking for is the z80 BASIC
01:38 AM rue_mohr: oh, right
01:38 AM rue_mohr: did you have e-waste stripdown on your list?
01:38 AM rue_mohr: er, yes
01:39 AM rue_mohr: tomorrow is garbage day, shall we just leave the alarm on?
01:39 AM rue_mohr: I suppose yea
01:39 AM rue_mohr: it might be nice to take a load of wood out
01:39 AM rue_mohr: its still wet, and we should do that going back and forth to work
01:40 AM rue_mohr: ok, but the dump trip is still on?
01:40 AM rue_mohr: yea, we better do that
01:41 AM rue_mohr: so, maybe we shouldn't stay up all night?
01:41 AM rue_mohr: but I'd like to work on the power supply, and we just ate we need to let that settle for like 4 horus or we wont get any sleep anyhow
01:42 AM rue_mohr: can I add automatic supper machine to the list?
01:42 AM rue_mohr: :]
01:42 AM rue_mohr: so?
01:42 AM rue_mohr: so?
01:43 AM rue_mohr: well, I guess I need to unlock the shop at SOME point
01:43 AM rue_mohr: what we gonna do tommroow
01:43 AM rue_mohr: well, finish greasing the truck front end
01:43 AM rue_mohr: talk to the shop about the suspension?
01:43 AM rue_mohr: I suppose
01:44 AM rue_mohr: but tomorrow
01:44 AM rue_mohr: lets plan
01:44 AM rue_mohr: I'm drawing a blank
01:44 AM rue_mohr: ok - garbage
01:45 AM rue_mohr: yes, well ok, yea, obvious
01:45 AM rue_mohr: your waiting on me aren't you
01:45 AM rue_mohr: yea...
01:45 AM rue_mohr: well, greasing the truck is for noon when it warms up a bit, so we need an inside thing or something
01:46 AM rue_mohr: - breakfast
01:46 AM rue_mohr: really?
01:46 AM rue_mohr: yea, I'm putting it on the plan
01:46 AM rue_mohr: ok, garbage, breakfast
01:46 AM rue_mohr: no, garbage, shower, breakfast
01:47 AM rue_mohr: how about this, I'll put the laundry on now, you can poke that in
01:47 AM rue_mohr: ok, garbage, shower, breakfast, laundry into dryer
01:47 AM rue_mohr: it wont be noon yet
01:47 AM rue_mohr: nup
01:48 AM rue_mohr: help me out, I'm all dopey
01:49 AM rue_mohr: casting, you wanted to do some casting
01:49 AM rue_mohr: were out of talc tho, and I dont want to drive around all over failing to find any
01:50 AM rue_mohr: ugh, that little shaker of it was NOT cheap on amazon
01:50 AM rue_mohr: is there another hydrophobic powder we can use?
01:51 AM rue_mohr: where is that list
01:52 AM rue_mohr: ok, garbage, shower, breakfast, laundry into dryer, finish big power supply, grease truck front end and change tires
01:52 AM rue_mohr: wait, you forgot about ma
01:52 AM rue_mohr: oh right
01:53 AM rue_mohr: ok, garbage, shower, breakfast, laundry into dryer, work on big power supply, get ma, work on big power supply, grease truck front end and change tires
01:53 AM rue_mohr: then some like indoor stuffs for the evening
01:53 AM rue_mohr: I'm not sure if we should work on the basic or something else

01:56 AM rue_mohr: ok, put a load of laundry on then
02:00 AM rue_mohr: ok done
02:00 AM rue_mohr: the power supply is gonna be so awesome!
02:00 AM rue_mohr: yea, your gonna melt lots of wires with that one
02:00 AM rue_mohr: we got the 20A limiter remmeber?
02:00 AM rue_mohr: right,
02:01 AM rue_mohr: gonna melt lots of wires with that one
02:01 AM rue_mohr: should we put a filter cap in it?
02:01 AM rue_mohr: maybe, but I'm wondering if we should round up the garbage now while we still have half a brain between us
02:01 AM rue_mohr: na, I'm sure it'll be fine
02:02 AM rue_mohr: ok
02:02 AM rue_mohr: do a list if you want
02:03 AM rue_mohr: bedroom garbage, bathroom garbage, catfood cans, kitchen garbage, shop garbage, and misc by the door
07:29 AM rue_mohr: todays a holdiday, maybe there is no garbage pickup

07:50 AM rifraf: ours was picked up good friday as well
07:56 AM rue_mohr: ok, almost there, shop garbage
08:03 AM rue_mohr: there seem to be a lot of surprised looking articles about how tourism crashed in the usa
08:04 AM rue_mohr: but its all about the lack of canadian tourists, and its really crashed across the board
08:04 AM rue_mohr: maybe they can get some tourists from el-salvadar.

08:35 AM rue_mohr: breakfast, laundry into dryer, work on big power supply, get ma, work on big power supply, grease truck front end and change tires, work on esp8266 serial bridge
08:42 AM rue_mohr: hmm, when did they start making addressable leds in 5mm?....
09:01 AM rifraf: tom or polprog, new version ready if you wanna test, alot more stable
09:01 AM rifraf: or you rue hopefully
09:03 AM rue_mohr: I have not made a top yet!
09:04 AM rifraf: 5 minutes with a bit of brass offcut
09:04 AM rue_mohr: heh, or steel...
09:04 AM rifraf: yep
09:05 AM rifraf: will show you some sexy graphs to inspire you
09:19 AM rue_mohr: ok breakfast done
09:20 AM rue_mohr: laundry into dryer, work on big power supply, get ma, work on big power supply, grease truck front end and change tires, work on esp8266 serial bridge
09:20 AM rifraf: rue_mohr take a look https://desire3d.com/images/public/shot1.jpg https://desire3d.com/images/public/shot2.jpg
09:21 AM rue_mohr: hey looks good
09:22 AM rifraf: is so cool
09:29 AM polprog: rifraf: sure happy to test
09:30 AM rue_mohr: polprog, wnhats the controller in the radio?
09:31 AM rue_mohr: ok, laundry in dryer and new load in washer
09:31 AM rue_mohr: work on big power supply, get ma, work on big power supply, grease truck front end and change tires, work on esp8266 serial bridge
09:31 AM polprog: rue_mohr: STA2052
09:31 AM polprog: I cracked the code
09:31 AM rue_mohr: ...
09:31 AM polprog: well, someone on the internet did it for me
09:31 AM rue_mohr: is that an 8051 variant?
09:31 AM polprog: I just dumped the flash
09:31 AM polprog: no, its a full blown ARM7
09:31 AM rue_mohr: oh
09:31 AM rue_mohr: so its arm!
09:34 AM polprog: gimme a sec and ill upload the photos
09:34 AM rifraf: polprog https://desire3d.com/images/public/vibesensing0.1.apk
09:35 AM rifraf: has better filtering, getting graphs like this now, https://desire3d.com/images/public/shot2.jpg
09:37 AM rue_mohr: the decay rate is cool, know the performance right away
09:37 AM polprog: rue_mohr: https://polprog.net/rozne1/ircjunk/golfradio/
09:37 AM polprog: https://polprog.net/rozne1/ircjunk/golfradio/pcb_front.jpg
09:37 AM polprog: its a radio+satnav combo
09:37 AM rifraf: yep, have to tweek that a little still, but is averaged decay
09:38 AM rue_mohr: ah
09:38 AM rue_mohr: did they have a serial interface to dump it, or did you ahve to go all jatag on it?
09:38 AM polprog: i had to go all jtag
09:38 AM polprog: use jlink tools to read the flash
09:38 AM polprog: J-Flash is pretty clever
09:38 AM polprog: you tell it the CPU core (ARM7), where the ram is and where the flash is mapped
09:39 AM polprog: and it uploads some tiny RAM code that then dumps the flash
09:39 AM polprog: you also have to give it the init sequence which writes some peripheral regs over JTAG
09:40 AM rue_shop4: oh!
09:40 AM polprog: https://polprog.net/rozne1/ircjunk/golfradio/RNS300_JTAG_pinout_CPT.jpeg
09:41 AM polprog: https://polprog.net/rozne1/ircjunk/golfradio/VID_20250418_124003731.mp4
09:41 AM polprog: :)
09:42 AM polprog: code 1002 <- saving for later if i loose it
09:42 AM polprog: plz dont steal my golf V
09:45 AM rue_shop4: I like it how people are starting to pronouce the signals with the n
09:47 AM polprog: what do you mean
09:47 AM polprog: rifraf: cool ill test it when i eat something
09:47 AM polprog: s/when/after
09:47 AM rue_shop4: I mean that, nrst
09:48 AM rue_shop4: "nrst" instead of just saying reset
09:48 AM rue_shop4: I have had a few :/ moments with youtube videos
09:48 AM polprog: its specifically called nRST and nTRST in jtag
09:48 AM polprog: its active low
09:48 AM rue_shop4: yea, they pronounce the n
09:48 AM polprog: why not
09:48 AM rifraf: polprog thanks, if you get any kind of graph data screenshot it and send please, even to show me what it looks like in other phone would be handy
09:49 AM polprog: enn-reset
09:49 AM polprog: rifraf: sure
09:49 AM polprog: ill show you the top too because its unusual
09:49 AM rue_shop4: you have a top!
09:50 AM polprog: i understood a lot more about jtag too
09:50 AM polprog: you just need to define what core it is and bang you can read registers, halt the CPU and do all sorta stuff
09:51 AM polprog: https://polprog.net/rozne1/ircjunk/golfradio/VirtualBox_10tools_17_04_2025_23_43_54.png
09:51 AM polprog: here i am editing memory, and this simple tui can do disassembly doo
09:51 AM polprog: same thing can be done with oocd and gdb on linux
09:55 AM rue_shop4: :]
09:55 AM rue_shop4: I have never had any success with jtag
09:56 AM rue_shop4: well, the most with your help on the stm32 stuff
09:56 AM polprog: its very picky about how it works
11:23 AM rue_shop4: work on big power supply, get ma, work on big power supply, grease truck front end and change tires, work on esp8266 serial bridge
11:23 AM rue_shop4: ma has a ride over, so
11:23 AM rue_shop4: work on big power supply, grease truck front end and change tires, work on esp8266 serial bridge
11:23 AM rue_shop4: I'll do the truck around 12 when its warmed up
11:57 AM rue_shop4: ok, I cant fit a capacitor in my power supply, so I guess its finished
11:57 AM rue_shop4: well
11:57 AM rue_shop4: sort of, I cant get the overload to trip
11:57 AM rue_shop4: I used 30A
11:58 AM rue_shop4: so I guess I should get a 20/25A one if I can
12:04 PM rue_shop4: huh
12:05 PM rue_shop4: its not warmed up yet, but I could set the truck up for greasing
12:22 PM Tom_L: where'd that crazy aussie go?
12:22 PM Tom_L: rifraf, settings don't appear to save when you say 'save'
12:22 PM Tom_L: page 2 'close' doesn't close that i can tell
12:24 PM Tom_L: page 1 is better but the buttons are still overlapping the bottom bar
12:29 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Screen_page1.jpg
12:29 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Screen_page2.jpg
12:29 PM Tom_L: you should move the parameters over so they are visible
12:29 PM rue_mohr: how do you describe tech-debt tom?
12:29 PM Tom_L: graph RPM
12:30 PM Tom_L: i don't
12:30 PM Tom_L: unable to do your own work?
12:30 PM Tom_L: so you cheat and steal it
12:31 PM Tom_L: rifraf, you should also look at pause/resume some. the logic isn't quite there yet
12:31 PM Tom_L: i
12:31 PM rue_mohr: http://media.ruemohr.org/images/p1340231.jpg
12:31 PM rue_mohr: http://media.ruemohr.org/images/p1340232.jpg
12:31 PM rue_mohr: http://media.ruemohr.org/images/p1340233.jpg
12:31 PM rue_mohr: http://media.ruemohr.org/images/p1340234.jpg
12:31 PM Tom_L: i'm not sure what triggered it but it was paused but still running
12:31 PM rue_mohr: so, thats the new power supply (and the old one it replaces)
12:31 PM Tom_L: i'll try to duplicate that behavior
12:31 PM rue_mohr: I think the old one is 1950's
12:32 PM Tom_L: rue_mohr, got an android yet?
12:32 PM Tom_L: rue_mohr, got a top yet?
12:32 PM rue_mohr: I need to make adjustments, the overload isn't triggering (30A) so I'll try a 20/25A one
12:32 PM Tom_L: rifraf seems to think you should
12:32 PM rue_mohr: yea I know
12:33 PM Tom_L: he needs your expertice
12:33 PM rue_mohr: I'm not sure $40 to try that app is helpful
12:33 PM Tom_L: i don't know anything about all that funny math
12:33 PM rue_mohr: or $100 depending on what phone I could get
12:33 PM rue_mohr: I'll work on making a top
12:33 PM Tom_L: you can get an S25 for $1k
12:33 PM rue_mohr: haha
12:33 PM Tom_L: i have a top now
12:33 PM rue_mohr: :]
12:34 PM rue_mohr: it sure didn't take him long!
12:34 PM Tom_L: no
12:34 PM Tom_L: i think he wanted an excuse to go visit the guys at the vo'tech anyway
12:35 PM Tom_L: ok rifraf, the pause/resume "BUG" happens when you go to the settings page with it paused and return to the main screen and it starts running with the 'resume' button showing
12:37 PM Tom_L: or maybe it's just the 'vibe leve'
01:25 PM rue_shop4: grease truck front end and change tires, work on esp8266 serial bridge
03:29 PM Tom_L: rifraf, ^
03:35 PM rifraf: tom thanks, the settings page is this morning mission, all you said it correct, did you get a smoother graph though, thats the biggest change and more 0 readings rather than all over the place when not spinning
03:53 PM Tom_L: i didn't try that hard once i saw it wasn't keeping the settings
03:54 PM Tom_L: i think it did seem smoother
03:54 PM rifraf: ignore setting, they are just for my debugging
03:55 PM rifraf: and none of them are working
03:55 PM rifraf: things should just work
03:55 PM Tom_L: *Sm
03:56 PM Tom_L: i should find a convex mirror so it will stay put longer
03:56 PM Tom_L: my desk isn't level
03:56 PM rifraf: yeah, interested to see what you come up with
03:57 PM Tom_L: for a mirror?
03:57 PM rifraf: year
03:57 PM Tom_L: probably a makeup mirror or something but it may be a while
03:58 PM rifraf: search ali for convex len as well
03:59 PM Tom_L: i'm not gonna order anything
03:59 PM Tom_L: get rue on board
04:01 PM rifraf: trying to
04:02 PM Tom_L: this version doesn't seem to be picking up the sound as well
04:02 PM rifraf: what sound?
04:03 PM Tom_L: vibe level 0
04:03 PM rifraf: its smoother
04:04 PM rifraf: i am avoiding vibrations more, ignoring low and some highs
04:05 PM Tom_L: on my desk with the phone on the desk i get very little result
04:06 PM rifraf: ok, is phone on sponge or something? i couldn't see many real readings on your screenshots so maybe your setup not isolating enough
04:06 PM rifraf: phone should not be direct on desk, we are dealing with another level of vibration, very small
04:07 PM Tom_L: i layed the phone on the glass to get much of any kind of a result
04:07 PM rifraf: then desk will not allow the phones sensor enough freedom
04:07 PM rifraf: ok i have good success with a thin layer of open cell foam
04:08 PM rifraf: slicecut up the wifes sponge etc
04:09 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Result1.jpg
04:10 PM rifraf: almost a line
04:11 PM rifraf: top only going fo 30 seconds or so? looks like fast start
04:12 PM Tom_L: yup
04:12 PM Tom_L: doesn't spin all that long
04:12 PM Tom_L: can i change the sample rate?
04:13 PM rifraf: you still should be able to get more readings, no you cannot, is set on the optimal
04:14 PM rifraf: you need to get the spin arena setup bit more i reckon
04:14 PM Tom_L: and a good top :)
04:15 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Result2.jpg
04:15 PM Tom_L: phone on glass
04:15 PM rifraf: now you are gettin it, see how much more consistent, and i guess it spun off the phone or something
04:16 PM Tom_L: with the phone off the glass i don't get a reading
04:17 PM rifraf: like balancing on a small shot glass or something? i did try that
04:19 PM Tom_L: doesn't seem sensitive enough here
04:20 PM rifraf: try other soft surfaces
04:21 PM Tom_L: i get nothing on my green work mat
04:21 PM Tom_L: in the top pic
04:21 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Brass_top1.jpg
04:21 PM Tom_L: i did before
04:22 PM rifraf: geez tom how many times do i have to say you need a special surface for the phone to sit on
04:23 PM rifraf: and cut a bit off the bottom of you top, increase COG just a bit for better spin times, and roughen the handle up
04:24 PM rifraf: this is a 12+ minute graph, example of what you can get and better even, have had spins where not a beat was off, https://desire3d.com/images/public/shot1.jpg
04:25 PM Tom_L: phone on sponge, top on glass, no reading
04:28 PM rifraf: ok, just experiment a bit, am getting very nice reading here with various tops
04:29 PM Tom_L: trying to level the glass
04:29 PM rifraf: yep best to have perfectly level
04:30 PM Tom_L: easier said than done
04:37 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Result3.jpg
04:38 PM rifraf: nice
04:38 PM Tom_L: need something convex but don't have it
04:39 PM rifraf: break bottom off bottle
04:39 PM rifraf: cut disk from plastic bottle
04:40 PM rifraf: old watch glass
04:41 PM rifraf: lens from old projector
04:46 PM Tom_L: went for 1:13 but the app didn't pick it up
04:52 PM rifraf: cool
04:53 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Result4_phone_on_glass.jpg
04:53 PM Tom_L: note the vibe level difference
04:53 PM Tom_L: do you want it at 0 or should it register something?
04:55 PM rifraf: 0 just means we don't have meaningful data
04:55 PM rifraf: so is rejected rather than displaying false readings
04:56 PM Tom_L: seems i always get 0 with the phone on the sponge
04:57 PM rifraf: try a small piece of sponge
04:57 PM rifraf: you are doing your best to isolate the phone from everything else, thats the mission
05:05 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Result5.jpg
05:06 PM Tom_L: thin washcloth on the glass with the phone on top of it
05:07 PM rifraf: can you take a picture of your setup? not sure what this glass is
05:08 PM Tom_L: 1/4" mirror
05:09 PM Tom_L: just standard mirror glass
05:12 PM rifraf: sitting direct on the phone screen?
05:13 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Mirror1.jpg
05:14 PM Tom_L: phone was sitting on the cloth on the glass in the last screenshot
05:14 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Result5.jpg
05:14 PM rifraf: its a very big mass to dampen the vibrations i think, and phone screen touching it directlt?
05:15 PM Tom_L: sitting on the cloth on the glass yes
05:15 PM rifraf: nono, a cloth just dampens it even more, thats your problem
05:15 PM Tom_L: no it isn't
05:15 PM Tom_L: the sponge is worse
05:15 PM rifraf: find a smaller thing to spin on
05:16 PM Tom_L: i don't have anything smaller that's flat
05:16 PM rifraf: you said you have phone then cloth then mirror, a cloth between with absorb most of the vibrations
05:16 PM Tom_L: what diameter are your convex lenses?
05:17 PM rifraf: 50mm
05:17 PM Tom_L: you told me to put the phone on the sponge to isolate it!!!
05:17 PM Tom_L: that didn't work
05:17 PM Tom_L: i put the phone on the cloth to isolate it
05:17 PM Tom_L: with a better vibe result
05:17 PM rifraf: but you still need like a ring around that,i there are tiny top spinning mirrow that have edge already
05:17 PM Tom_L: i got what i got
05:18 PM rifraf: wifes makup bag, will be a small travel magnifying mirror, ie, convex, they all have one
05:18 PM Tom_L: i'd keep the code for your setup since it seems to work
05:19 PM rifraf: heh i have kept many copies don't worry
05:19 PM Tom_L: the text is alot better
05:19 PM Tom_L: you could raise the buttons up so they clear the bottom bar
05:19 PM Tom_L: and fix whatever needs fixed on page2
05:20 PM rifraf: been workin on it
05:20 PM Tom_L: i made a top. i'm one up on rue
05:22 PM Tom_L: what are your vibe level numbers?
05:22 PM Tom_L: what sort of start rpm do you get?
05:23 PM rifraf: 0 when running unless i bump phone or tilt it
05:23 PM Tom_L: ok
05:23 PM rifraf: unless top has alot of vibration, then 20 to 40
05:23 PM Tom_L: you said 0 discards data though
05:23 PM rifraf: zero just ignored, won't plot on graph
05:24 PM Tom_L: but the idea is to get a plot
05:24 PM Tom_L: so you need some vibe
05:24 PM Tom_L: ehh?
05:25 PM Tom_L: i'll just pretend to understand what's going on since the math is over my head
05:25 PM rifraf: i will turn the vibe up a bit for you then
05:26 PM Tom_L: don't fix it for my setup because it's not an ideal setup
05:26 PM Tom_L: i can adjust things until i get a plot :)
05:26 PM rifraf: go look through your recycling bin\will be an object you can modify
05:27 PM Tom_L: i could do alot of things but sitting on my ass doing nothing is very appealing atm
05:27 PM rifraf: most glasses and bolles have concave surface, cut bottle off on with hot wire
05:27 PM Tom_L: is a 6" concave mirror too big?
05:28 PM Tom_L: all we have is plastic crap to drink from
05:28 PM rifraf: but you can put plastic on your phone directly without an issue, cut bottom on your plastic cup then
05:30 PM Tom_L: i'm not putting anything on this phone. it's brand new and i don't care to take a chance breaking the screen
05:30 PM rifraf: you just gotta look around in the cupboards, an one thing just magically disapperas, and you cut it up to work
05:30 PM rifraf: come on, the glass is stronger than you these days, and you should have a replacement cover on it anyways
05:31 PM Tom_L: i do
05:32 PM rifraf: so stop being soft, heck i have a brass ring and glass on mine without a protective cover
06:14 PM rifraf: sour cream lid
06:17 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rifraf/Result6.jpg
06:17 PM Tom_L: the last bit couldn't possibly be accurate
06:18 PM Tom_L: sitting on the phone
06:18 PM Tom_L: (spare phone)
06:18 PM rifraf: bottom of every beer can, spice jar lid
06:18 PM rifraf: common things i found in quick look
06:19 PM rifraf: get a small thing to spin it on
06:20 PM rifraf: your results not optimal yet at all
06:23 PM Tom_L: i should put a divet in the tip and put a ball point pen ball in it
06:29 PM rifraf: bigger ball better, you will get nice 4mm ones from a skate board bearing
06:29 PM rifraf: but just round off your brass a bit for now
06:30 PM rifraf: tips not that important till you are going past the 5 minute mark
06:30 PM Tom_L: i don't plan to go that far
06:30 PM rifraf: its addictive
06:30 PM Tom_L: i'm testing software
06:31 PM rifraf: good stress relief while testing
06:31 PM Tom_L: so is vodka
06:32 PM Tom_L: what's your top spin time?
06:33 PM rifraf: top standard spin about 15 minutes
06:34 PM Tom_L: test one in a vacuum
06:34 PM rifraf: i have an anti gravity device that lets me get over 1 hour
06:34 PM Tom_L: i saw that contraption
06:34 PM Tom_L: or one you were looking at
06:35 PM rifraf: it evens registers well with this app for the first 30 minutes or so, then speeds get too slow
06:35 PM rifraf: one i made
06:35 PM rifraf: still waiting on the levitation unit, has been ages since ordering
06:35 PM rifraf: it won't spin longer, just will be a cool thing
08:36 PM rifraf5: Tom_L https://desire3d.com/images/public/settings2.jpg
08:40 PM rifraf5: you tweek setting till it displays close to what you weighed, with a shape like yours should come out pretty accurate, and you can just select materials, because hard to weigh the core of a bimetal top
09:05 PM Tom_L: where did you find that?
09:05 PM rifraf: what?
09:06 PM Tom_L: the moment of inertia settings
09:06 PM Tom_L: is that your new page 2?
09:06 PM rifraf: calculated them, drew the image etc
09:06 PM rifraf: yes
09:06 PM Tom_L: ahh ok
09:06 PM Tom_L: new apk uploaded?
09:07 PM rifraf: not yet
09:07 PM rifraf: the settings are yet to interact with main page
09:08 PM rifraf: but is calculating mass well depending on materials and dimentions entered
09:10 PM rifraf: you can use 3d printed or resin printed tops
09:14 PM rue_mohr: oh, I got the tires changed
09:14 PM rue_mohr: work on esp8266 serial bridge
09:14 PM rue_mohr: oh yea, the serial bridge
09:17 PM Tom_L: by the time rue comes on board you'll have the app perfected
09:18 PM rifraf: but he might have another few leds blinken on his serial bridge
10:29 PM rue_mohr: while I was greasing the steering on the truck, one of the nipples pulled off with the grease gun, I had some spares, but I'v never had that happen before
10:30 PM rue_mohr: the threads were ok, I guess it somehow worked its way out
10:30 PM rue_mohr: I think both my front brakes are dragging a bit
10:30 PM rue_mohr: the pads dont release free and I'm sure they should
10:31 PM rue_mohr: I'm glad I got that power supply done up
10:31 PM rue_mohr: been wanting that for a long time
10:32 PM rue_mohr: the old one is a bit weak
10:40 PM rifraf: rue_mohr https://desire3d.com/images/public/settings2.jpg
10:42 PM rue_mohr: ah cool
10:45 PM rifraf: you can tweek the heights till it matches your weighed value, and will be pretty spot on with KE calcs then
10:46 PM rue_mohr: can you add steel to the list
10:46 PM rue_mohr: I'm just going to do mine from steel
10:46 PM rifraf: steel is in the list, along with tungsten or titanium
10:47 PM rue_mohr: ok!
10:47 PM rifraf: even pla or petg in case you wish to print
10:47 PM rifraf: even foam resin or aerogel
10:49 PM rifraf: i can recompile for every android if it would help you?
10:49 PM rue_mohr: oh, which one did I have working?
10:49 PM rue_mohr: the lg
10:50 PM rifraf: wanna try a new apk file?
10:50 PM rue_mohr: hold on
10:50 PM rue_mohr: oh I could not get the android version from it
10:50 PM rue_mohr: I dont know what version to ask for
10:50 PM rifraf: just try install it
10:51 PM rue_mohr: ok
10:51 PM rue_mohr: give me new link!
10:52 PM rue_mohr: wtf where is my bag of sd cards
10:52 PM rifraf: https://desire3d.com/images/public/vibesensing0.2.apk
10:52 PM rue_mohr: got one
11:13 PM rifraf: yay any luck?
11:15 PM rue_mohr: I cant do this via sd card, there is no file browser
11:15 PM rue_mohr: but I can acess my machine by http, so I'll try that
11:17 PM rue_mohr: "there is a problem parsing the package"
11:18 PM rifraf: bugger
11:19 PM rue_mohr: but I can try to jumpstart one of the newer ones
11:22 PM rifraf: jumpstart it rue, you can do it
11:25 PM rue_mohr: eatin supper
11:25 PM rue_mohr: all good things come in time
