<zmatt> \n
<zmatt> and that has nothing to do with formatted strings, that's just strings in general. python3 -c 'print("foo\nbar")' prints two lines, "foo" and "bar"
<zmatt> (a formatted string (aka f-string) is just a convenient way to format data into a string, it has nothing to do with the meaning of control characters in a string like \r and \n and their effect when printed to a terminal)
<mattb0ne> doh
<zmatt> (which is that \r moves to the start of the current line while \n moves to the start of the next line)
<zmatt> (sort of. technically \n just moves down one line and \r\n is required to move to the start of the next line, however \n is normally automatically converted to \r\n by the tty layer in the kernel so there's no point in explicitly printing \r\n instead of just \n)
<zmatt> (and of course when I write \r or \n I mean the single character represented by writing that escape sequence inside a quoted string in python (or various other programming languages), the string itself does not contain a backslash... len("\n") is 1)

<Konsgn> zmatt, thats a good sales pitch. ;)
<zmatt> it's helping someone not look for something in a place where he definitely won't find it :P

<zmatt> nice temporal causality loop, or more like temporal causality directed graph lol
<zmatt> disagree with wikipedia's choice to call it paradoxical, it seems self-consistent to me
<Konsgn> haha, you wiki'd it?
<zmatt> yeah never heard of it
<Konsgn> read it first, it's only like 4 pages
<Konsgn> I guess it's too late for that... it is fun though.
<zmatt> yeah too late, basically the first thing I read was an unmarked total spoiler
<zmatt> have a link?
<Konsgn> Thought it was vonnegut at first, ended up digging through all his collections with no avail.
<Konsgn> yup, one sec
<zmatt> thanks
<Konsgn> Np.
<zmatt> it's a bit silly so far
<Konsgn> Haha, It doesn't stop being silly.
<Konsgn> apparently they made a movie based on it.

<set_> I made it!
<set_> I am learning about Linux and how libc handles cross-compilation!
<set_> So, w/ a toolchain, the kernel, and a system like buildroot or yoctoproject, I can build immensely and appropriately...
<set_> I know...old news, old news.
<set_> But! I am learning something new w/ crosstools-ng. Is anyone aware of their toolchains?
<set_> What you guys do is not easy.
<set_> I am starting to learn slowly. All that CC business must get tedious and mundane. Anyway, off to read more.
<set_> I have a heavily generalized book w/ specifics later on says the writer. Anyway, things are getting interesting!

<Guest89> Hello! hope you are well. i was curious if you had any STEP file or some such similar 3d model of the beaglebone AI board so i might construct myself a cooling fan duct and post the STL to thingiverse or give you the file.
<Guest89> i'm a mechanical/electrical R&D engineer for a decently large outfit. I specialize in designing, manufacturing, testing, and optimizing hardware manufacturing processes for our factories. as well as building custom parts/automated custom industrial equipment.
<Guest89> machining/cnc programming/welding/metal fab. you name it.
<Guest89> However, up until this point i have based all my machines on button control panels with basic ladder logic PLC's
<Guest89> Now they want touch screen GUI control stuff. so im fixin to learn to code properly. starting out in QTcreator.
<Guest89> if you have any helpful resources or recommendations i'd always be open to anything you suggest :)
<set_> Guest89: look at that github link. It may help you on your journey.
<Guest89> this is going to sound awful. but how do i download that file from github
<set_> Oh.
<Guest89> my programming skills are neigh on total novice lol
<Guest89> im a hardware guy. i can make about any kind of part. circuit board. machine. or anything you need. but ive never gone beyond the cad work and simulations i do in computers.
<set_> Okay! Try git. Do you use debian or ubuntu at all?
<Guest89> a tinsy bit.
<set_> apt install git
<Guest89> on any of the fancier stuff ive done i cheated and used matlabs/simulink/stateflow to make state charts to generate code from. but i'd like to find some good starting points where i can grasp the base concepts and start applying them to problems
<set_> Aw!
<set_> Me too!
<set_> I love some issues.
<Guest89> i was following along here getting this stuff. and got to the Install BoneScript and setup a pin for use:
<Guest89> cd /usr/local/lib⏎
<Guest89> sudo npm install --unsafe-perm bonescript@0.7.4-beta1⏎
<Guest89> node -pe "require('bonescript').bone.getPinObject('p9.15').ai.gpio" (this sets up the pin in /sys/class/gpio) portion
<Guest89> and when i ran the node -pe deal. it froze up and lost connection.
<Guest89> it was also fairly warm. so i am going to make it a nice cooling duct :)
<set_> Oh. I think the .org people are phasing out the bonescript stuff.
<set_> Oh!
<set_> The AI, you mean?
<set_> Yep...it needs a fan.
<Guest89> all i have is a big fan and im trying to use the screw terminal block cape so im making a doo-dad to sit to the side and blow air in between the cape and BBAI while forcing most of it directly over the main processors heat sink
<set_> Nice.
<set_> That should be your calling!
<set_> Make it, do not break it!
<set_> Or like GenTooMan, if that person would ever come back, says, "Break it and figure it out!"
<Guest89> i find being able to inspect things under high magnification is often helpful to understand basic mechanical concepts. :)
<Guest89> so i try to download that and get a page filled with the raw text data of the step file.
<set_> All jokes aside, that is the stp file.
<set_> I think w/ KiCAD, you can make it work.
<Guest89> i mean. as far as the jargon and various whatevers like the bonescript or anything. assume i have zero idea what you are talking about lol
<set_> Oh.
<set_> Okay.
<set_> No issue.
vagrantc has joined #beagle
<set_> I will try it.
<Guest89> but not just a .stp file i can import in inventor eh? :P may be quicker for me to just measure
<set_> I think if you download the file and use your CAD source to open it, it may work. If not, I can try to remember how to handle the stp files in KiCAD.
<set_> Dang it.
<set_> This may take longer than expected. I just erased all my KiCAD stuff.
<Guest89> o.o oof
<set_> Ha.
<Guest89> sorry to make you go through the trouble
<set_> No issue.
<set_> I can figure it out. Give me a couple days.

<TheMysticTurtle> we havent met before. i just thought mystic turtle might be a tad bit easier to remember than guest89 lol
<TheMysticTurtle> but i have a terrible recollection of names as well
<set_> Oh! Got it. Okay.
<set_> I am installing it now.
<set_> Brb
<set_> Okay! Thing(s) may be going smoothly.
<set_> I started the repo, updated, and am now installing kicad on Buster.
<set_> Oh...Sunny Days.
<TheMysticTurtle> haha
<TheMysticTurtle> i'm still here. just modeling away
<set_> Okay. Things are completed.
<set_> installed! Now, off to find the way.
<set_> please stay w/ patience...

<set_> TheMysticTurtle!
<TheMysticTurtle> hi :D
<set_> I know I am lame but I found something that may be of interest.
<TheMysticTurtle> you arent lame lol
<set_> Okay, okay.
<TheMysticTurtle> i wont lie to you. im halfway done modeling the air cooling duct
<set_> Forget that mess.
<set_> Ha.
<set_> Okay...
<TheMysticTurtle> you have discord?
<set_> Yes.
<TheMysticTurtle> ah. you should add themysticturtle#3248 :D
<TheMysticTurtle> then i can share cool pictures of said air duct
<set_> Oh. Okay.
<set_> Thank you.
<set_> The rain showed up. BBL!
<set_> Hey...
<TheMysticTurtle> id also be happy to help teach you about any facet of manufacturing or electrical circuit design in exchange for some assistance as i dip my toes into this unfamiliar water lol
<set_> Sorry.
<set_> I already have too much on my plate but!
<set_> I found something you may like w/in KiCad.
<TheMysticTurtle> that sounds nifty
<set_> They have a BBB (old model) Cape listed in their main kicad-libraries.
<TheMysticTurtle> i understand the full plate. for sure. but feel free to add me on discord if you'd like to keep in touch better or see random neat updates or have a good resource for questions you come across :D
<set_> I am sure you can alter it and mush it up!
<TheMysticTurtle> (i also do not know what kicad is) i have a full seat of the autodesk creative design and manufacturing suite.
<set_> TheMysticTurtle: I am terrible w/ friendships. Ask anyone.
<set_> Oh.
<set_> Okay.
<TheMysticTurtle> or rather my employer pays for that and matlab/simulink/stateflow
<set_> Hey. Let me take this screenshot to show you exactly what i am describing.
<TheMysticTurtle> you can share screen shots on this chat?
<set_> No.
<TheMysticTurtle> i tried earlier and couldnt. thats what brought up discord haha
<set_> https://imgur.com/d8776sU is the photot.
<TheMysticTurtle> oh that bit is easy. :D
<set_> Oh.
<set_> Okay.
<set_> so, you need the stp file still though. Okay. I will need more time.
<TheMysticTurtle> no worries
<TheMysticTurtle> you dont need to mess with it. im almost done making my fan duct with measurements off of the actual board and my mitutoyo dial calipers lol
<set_> I enjoy helping if I can. It is like an illness.
<set_> Oh.
<set_> Okay.
<set_> No worries and no issues.

<Konsgn> made it to the server roll-over?
<set_> Not me. Maybe GenTooMan?
<set_> Anyway...time to go and cry in the outdoor areas again. Argh.
<set_> BBL!
<Konsgn> ... what is bbl?
<zmatt> be back later
<Konsgn> beagle bone lite?
<Konsgn> ahh, that makes more sense
<Konsgn> followed immediately by beagle bone dark
<zmatt> I'm waiting for the beaglebone hot-pink
<Konsgn> everyone knows racing stripes make the cpu run faster
* GenTooMan likes the beagle bone lite idea.
<zmatt> I mean, there's already the BBG and the pocketbeagle
<GenTooMan> Try aka beagle bone minime

<set_> sweet...sorry.
<set_> I have noticed some other mfg. are promoting am335x styled boards. Is anyone using one of these boards?
<set_> For instance, I saw on the TI site that there were some alternatives. I also saw that a fellow at digikey was speaking to someone about those am335x concerns.
<set_> Does anyone know offhand the Physical hex for the debug UART on the BBB?
<set_> Bosch even has an am335x board too!
<set_> "There is no biz like bzzt!"
<set_> The base address in hex format for the debug uart is what i am after. Anyway, do you think I could find this in the am335x TRM?
<set_> Keyword "I" here. Ha.
<zmatt> why would you need that?
<set_> Oh.
<set_> I am building an image w/ crosstool-NG and buildroot and u-boot.
<zmatt> ... okay, and?
<set_> I came across some new ideas in the u-boot make menuconfig.
<zmatt> u-boot knows what uart to use based on board identification
<set_> Oh. Okay. Okay.
<set_> I will try to use the right tool again instead of relying on u-boot.
<zmatt> also, why are you messing with buildroot anyway?
<set_> B/c...it is fun and exciting.
<set_> new tools, new boards, new news!
<set_> I am excited to be a user in the realm of making for now but things will change. Give it time, sire.
<zmatt> you have enough trouble getting things working on a normal debian system, I don't see how using a customized stripped-down buildroot image could possibly be of any benefit for you
<set_> And and and...
<set_> Geez.
<zmatt> you do you, afk
<set_> afk means nothing as I know you are upset now b/c I want to venture into the unknown (for me).

<RossSchulman[m]> Does there exist anywhere a regularly updated list of common types of components and a range of popular solutions for each category? So like what are people using most often now for (e.g.) a wifi/bluetooth component?
<RossSchulman[m]> I know there are a ton of variables that would go into any decision but it might be helpful to have a place to start other than just typing "wifi" into digikey.
