12:04 AM katsumi: or just version control?
12:08 AM rue_mohr: ok I need to update 3 files on
12:08 AM rue_mohr: https://github.com/ruenahcmohr/TapeRunner
12:08 AM rue_mohr: there
12:13 AM katsumi: mom#
12:13 AM rue_mohr: ?
12:14 AM rue_mohr: ok
12:14 AM rue_mohr: sofar, I cloned the project https://github.com/ruenahcmohr/TapeRunner
12:15 AM rue_mohr: changed the files
12:15 AM Jak_o_Shadows: cool.
12:15 AM rue_mohr: and did git add *
12:15 AM rue_mohr: your configuration file:
12:15 AM rue_mohr: git config --global --edit
12:15 AM rue_mohr: After doing this, you may fix the identity used for this commit with:
12:15 AM rue_mohr: git commit --amend --reset-author
12:15 AM rue_mohr: 3 files changed, 13 insertions(+), 8 deletions(-)
12:15 AM rue_mohr: and this sounds about right
12:15 AM rue_mohr: ?
12:15 AM Jak_o_Shadows: yes
12:15 AM Jak_o_Shadows: i mean, the author bit might be messy, but meh.
12:15 AM rue_mohr: ok, then I need to send them to master?
12:15 AM Jak_o_Shadows: yup, with git push
12:16 AM rue_mohr: username:password?
12:16 AM rue_mohr: has to go soemwhere
12:17 AM Jak_o_Shadows: i think it will prompt you
12:17 AM rue_mohr: :)
12:26 AM katsumi: but why --reset-author?
12:26 AM katsumi: meh... i'm stupid one
12:26 AM rue_mohr: ?
12:26 AM rue_mohr: I dont know
12:27 AM rue_mohr: it looks like git dosn't care who you are till you commit
12:29 AM katsumi: i have absolutely no idea
12:32 AM Jak_o_Shadows: that is true. Git does not care who you are until you commit
12:32 AM Jak_o_Shadows: and I don't think it cares who you are at any other point

12:40 AM rue_mohr: hmm
12:40 AM katsumi: :)
12:40 AM rue_mohr: its a logo for a casette tape.
12:40 AM rue_mohr: you dont know that logo?
12:41 AM katsumi: no
12:41 AM rue_mohr: WAAAAA

12:49 AM katsumi: kk
12:49 AM katsumi: mom#
12:50 AM rue_mohr: NC used to be on paper tape
12:50 AM rue_mohr: then on magnetic tape
12:50 AM rue_mohr: thats why its called tape runner
12:50 AM rue_mohr: it runs NC tapes
12:50 AM rue_mohr: " "
12:51 AM katsumi: wait i have to switch off my indian proxy... to many hackers on
12:51 AM katsumi: lol
12:52 AM katsumi: ERROR: Gateway Timeout
12:53 AM katsumi: aaah
12:54 AM katsumi: cool

01:27 AM katsumi: so
01:27 AM katsumi: billyzane: ask rue
01:28 AM katsumi: due to time zone maybe hes aslleep
01:28 AM rue_mohr: no I dont sleep
01:28 AM katsumi: lol
01:29 AM katsumi: ok, i'm goin to get the proxy clean
01:30 AM katsumi: laterz
01:34 AM katsumi: ha, proxy works
01:44 AM katsumi: posession is lost
01:45 AM katsumi: let the sun fall into the ocean

01:50 AM katsumi: i fckn luv laibach
01:53 AM katsumi: https://www.youtube.com/watch?v=zN2E_ovp6IQ
01:53 AM katsumi: wild b-machine
01:56 AM BillyZane: rue_mohr, hi
01:57 AM BillyZane: rue_mohr, i am looking in to getting in to robotics
01:58 AM BillyZane: rue_mohr, my education background: B.S. applied math, and i've taken a few CS classes like data structures. i got a little bit of introductory knowledge in python, java, C, matlab
01:59 AM BillyZane: i'm looking in to being able to do the following
01:59 AM BillyZane: build a commercially viable robot that solves a task a worker would normally do
02:00 AM BillyZane: but i'm a bit overwhelmed
02:00 AM BillyZane: i'm trying to focus on learning ROS2
02:01 AM BillyZane: what i need help with is picking a suitable board
02:01 AM BillyZane: i have a raspberri pi 3B+
02:02 AM BillyZane: but i want to run a real time kernel
02:02 AM BillyZane: and the pi seems to lack a clock
02:02 AM rue_mohr: heh
02:02 AM katsumi: how to avoid a alpha 1 hand axis singularity?
02:03 AM rue_mohr: BillyZane, have you ever built a robot before?
02:04 AM BillyZane: rue_mohr, no sir
02:04 AM BillyZane: rue_mohr, i don't mean to say i could achieve my goal overnight. i will need to do basic stuff first
02:04 AM BillyZane: rue_mohr, but what i'm looking for is 1) a strategy , 2) best practices, 3) recommended tools
02:05 AM katsumi: it's nine o'clock
02:05 AM katsumi: how to avoid a alpha 1 hand axis singularity?
02:05 AM BillyZane: rue_mohr, right now i'm mostly confused about the variety of hardware, and also my understanding of linux is fairly basic
02:08 AM BillyZane: rue_mohr, i'm also inexperienced with electronics and computer hardware. being able to, for example, read the output of a sensor or analog data stream is something i've never done
02:08 AM BillyZane: so, what do you recommend?
02:09 AM BillyZane: i should also note that i'm working at a shipyard and i work at a restaurant
02:09 AM BillyZane: so my time is limited
02:09 AM BillyZane: but i'm looking for a new day job, if i can work less hours, i can free up hours to study at least 25 hours a week
02:11 AM BillyZane: i've been going a number of approaches
02:11 AM BillyZane: for one, i'm trying to find text books on the topic
02:12 AM BillyZane: but this technology is moving too fast
02:12 AM BillyZane: and ros2 doesn't have a book that i know of.
02:12 AM rue_mohr: I recommend building anything
02:13 AM rue_mohr: get an arduino and a servo, make it do something amusing
02:14 AM BillyZane: i have a raspberri pi 3B+, i could try doing the servo trick in python perhaps?
02:14 AM rue_mohr: tooo slow
02:14 AM BillyZane: may i ask why too slow
02:14 AM rue_mohr: too much software
02:15 AM rue_mohr: do you know C?
02:15 AM BillyZane: i have some experience in C
02:15 AM rue_mohr: ok, use an arduino
02:15 AM rue_mohr: less software, faster responce
02:16 AM BillyZane: are there C libraries for the GPIO pins on the raspberri pi
02:16 AM rue_mohr: make a stuffed bear wave a sign for a tip jar at work or something
02:16 AM BillyZane: lol
02:16 AM BillyZane: that sounds kinda cool
02:16 AM rue_mohr: BillyZane, the Pi has too much going on, a 16Mhz arduino will be faster than a 2Ghz Pi
02:16 AM rue_mohr: Bloatware
02:17 AM rue_mohr: and the arduino is cheaper
02:17 AM rue_mohr: and there is more support for operating a servo
02:18 AM rue_mohr: the arduino should be $3, the servo should be $1.50
02:18 AM rue_mohr: if you spend a lot more than that, your doing it wrong
02:19 AM BillyZane: i have an esp8266
02:19 AM BillyZane: and i have some sensors that can detect moisture
02:19 AM rue_mohr: no
02:19 AM BillyZane: i don't have a motor though, but i can try getting one
02:19 AM rue_mohr: use atmega328 based arduino
02:19 AM rue_mohr: this is what I suggest!
02:19 AM rue_mohr: servo, 9g
02:20 AM BillyZane: as far as C goes, i've taken a class called 'operating systems'
02:20 AM BillyZane: and one called 'parallel computing'
02:20 AM rue_mohr: https://www.aliexpress.com/item/Classic-servos-9g-SG90-For-RC-Planes-Fixed-wing-Aircraft-model-telecontrol-aircraft-Parts-Toy-motors/32961322401.html
02:20 AM BillyZane: and both classes were entirely in C
02:21 AM rue_mohr: https://www.aliexpress.com/item/high-quality-One-set-UNO-R3-CH340G-MEGA328P-for-Arduino-UNO-R3-NO-USB-CABLE/32697443734.html
02:21 AM BillyZane: that's going to take a month to arrive right
02:21 AM rue_mohr: first test is to attach those two and make the servo move
02:21 AM rue_mohr: if you pass that, you may advance
02:22 AM BillyZane: i see
02:22 AM rue_mohr: it is simple, you should succeed
02:22 AM BillyZane: should i be reading the signals from the cables
02:22 AM rue_mohr: no
02:23 AM rue_mohr: google search attaching arduino to servo
02:23 AM rue_mohr: look at webpages and youtube videos
02:23 AM rue_mohr: get hardware, succeed, make funny thing, advance to next level
02:28 AM BillyZane: i order stuff on that website often and it takes weeks
02:28 AM BillyZane: sigh
02:28 AM rue_mohr: yup
02:28 AM rue_mohr: you said you dont have much time
02:28 AM rue_mohr: order now and it'll be here before you have a change to argue about getting something else
02:28 AM rue_mohr: chance
02:28 AM rue_mohr: in the meantime figure out what to make it move
02:28 AM BillyZane: i see
02:29 AM BillyZane: how do you troubleshoot
02:29 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/3rdarm/p1120682.jpg
02:29 AM rue_mohr: $20
02:30 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm9/p1060858.jpg
02:30 AM rue_mohr: $20
02:30 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/mowerbot/p1020962.jpg
02:30 AM rue_mohr: $20 (tho a few times with upgrades)
02:31 AM BillyZane: do you live in africa
02:31 AM Jak_o_Shadows: I just bought 4/5/6? 1Nm stepper motors for about $5AUD each.
02:31 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090284.jpg
02:31 AM rue_mohr: $20
02:31 AM Jak_o_Shadows: They're a decent start
02:32 AM BillyZane: rue_mohr, what controllers do you normally use?
02:32 AM rue_mohr: AVR
02:32 AM rue_mohr: aka arduino, but I don't use the arduino stuff
02:32 AM Jak_o_Shadows: I use the STM32 blue pills
02:32 AM Jak_o_Shadows: albeit I never do too much
02:32 AM rue_mohr: I'm working on upgrading to bluepill
02:33 AM rue_mohr: but not because of speed
02:33 AM Jak_o_Shadows: Peripherals?
02:33 AM rue_mohr: because microchip is a messed up company and AVR will not be available in the long term
02:33 AM Jak_o_Shadows: aha
02:33 AM Jak_o_Shadows: fair enough
02:34 AM Jak_o_Shadows: The peripherals in the ARM's are pretty neat, once you figure out how to turn them on
02:34 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/armcontroller2/p1070298.jpg
02:34 AM rue_mohr: $20
02:34 AM Jak_o_Shadows: and then remember to turn their clocks on
02:34 AM rue_mohr: yea, gee, lots of overhead codewise compared to avr
02:35 AM Jak_o_Shadows: yeah, tell me about it
02:35 AM Jak_o_Shadows: I never remember to turn the clocks on. And of course it doesn't work.
02:35 AM rue_mohr: http://ruemohr.org/ BillyZane check over the site if you want
02:35 AM BillyZane: rue_mohr, nice
02:36 AM rue_mohr: Jak_o_Shadows, you got the makefile I had adjusted didn't you?
02:36 AM Jak_o_Shadows: I did, somewhere
02:36 AM Jak_o_Shadows: but nah, this is for work stuff
02:36 AM rue_mohr: I think you found a python version of the .. awk? script I relied on
02:37 AM Jak_o_Shadows: oh, yeah.
02:37 AM Jak_o_Shadows: I remember that now.
02:37 AM Jak_o_Shadows: Nowadays I just have a zip copy of the one time I got that working
02:37 AM Jak_o_Shadows: At work, we aren't doing anything as flaky as that
02:37 AM rue_mohr: :)
02:39 AM rue_mohr: gnight
02:44 AM Jak_o_Shadows: nn
02:58 AM katsumi: https://www.youtube.com/watch?v=FStYdOcDl00
02:58 AM katsumi: lol
03:01 AM rue_bed: your supposed to be searching how to control a servo with an arudino
03:14 AM katsumi: I'm the king of microwave
03:54 AM katsumi: jammi
04:42 AM Jak_o_Shadows: ? rue? I mean, that's not too hard?
04:42 AM Jak_o_Shadows: You've got a decent page about it as well
04:46 AM mrdata: just a single servo?
04:46 AM mrdata: a hobby servo perhaps??
04:46 AM mrdata: there is an API for it i think
08:23 AM veverak: hmm
08:23 AM veverak: is there a decent app for remote control of robots on ios?
08:23 AM veverak: so far it seems like everyone reivented wheel for their robot
08:51 AM rue_mohr: :) makea new one!! one for everybody!
08:51 AM rue_mohr: a new, better standard!
09:04 AM polprog: telnet + curses TUI :D ?
09:05 AM polprog: and vim keys for movement
09:05 AM polprog: :D
09:16 AM veverak: rue_mohr: reminds me of https://xkcd.com/927/
09:16 AM veverak: polprog: that hardly works as joystick
09:16 AM veverak: :(
09:17 AM polprog: you just have to PWM the keys
10:33 AM azy: imagine this: boston dynamics walking robot forms itself into a swingset... and swings itself super fast to launches itself into the air/wherever to land in a desired position
10:33 AM azy: what am i missing
10:33 AM azy: that seems somewhat possible
10:33 AM veverak: it should be
10:33 AM azy: a low energy way of going places
10:33 AM veverak: but good luck with coding that and having HW that can withstand that
10:33 AM veverak: :)
11:25 AM deshipu: https://www.bostondynamics.com/sandflea
11:34 AM azy: hows it doing that
