Just days ago we wrote about an open source 3D printed microscope that could be made for as little as '100. Now, another project, undertaken by researchers from the University of Bath, has even higher aspirations than that as it has made a prototype of a 3D printed microscope for only £30.

just finished baking double chocolate cookies spiced with ginger and cayenne sweats
anyone else here bakes :D?
I want to practice, but I don't have the ingredients.
I should have put more ranch on it.
They sound great @abstract violet
I can bake a little, for some reason I've signed up to do our wedding cake...
This is the height of my baking so far
My girlfriend made the fondant pandas though

@indigo jetty That is ADORABLE!

I just found this community, and I am super excited to have joined. I am interested in getting a 3D printer for myself and my family (My wife and I are really into hobbyist technology, and we are trying to raise our children to be technologically savvy as well.) If I were to buy a 3D printer on a $1,000.00 budget what would be the best one to purchase?
@keen venture welcome! You might be better off asking in #help-with-3dprinting
@keen venture I have (and love) the Prusa i3Mk2S (about 900 USD)
Thanks @indigo jetty . I didn't know if that was a good place to ask. And @polar wraith Cool, that is one that I was looking into. How loud is it? (I ask because that seemed to be the only consistent complaint.)
@indigo jetty those look fantastic! I love chocolate cake! -- the pandas turned out!
@keen venture welcome \o/
@keen venture I run it in my apartment and I can barely hear it in the next room.
James's Tech Reviews! Episode 1 With thanks to www.upclosefilms.com and www.sergey.video
In the future....
Well, I have 2 children (10 and 6) and I really am trying to raise them with an overwhelming familiarity for technology. This summer my 10-year-old daughter and I built a retro gaming machine out of a Pi 3 and my wife and she just started a dedicated dakboard build so they could have a family calendar as we start the school year. We just are increasingly thinking that a 3D printer is the next logical piece of technology that we should pick up to “play” with when we find ourselves with the time.
At least that is how I am justifying it.
@keen venture the prusa as @polar wraith is a solid printer, just have to wait a while to get one..
or not!
"With our new factory, we’ve reduced the lead-time down to 1 to 2 weeks! Hoooray!"
was around 6
Cool @abstract violet, so is buying direct the best way to go?
if you can find a local distributer, why not? @keen venture
oh cool, I should build a dakboard
my kids are 7 and 4, so the oldest is at a prime age
(hence me buying the new electronics book from adafruit yesterday, with their perfectly-timed 10% off code)
Indeed. We found a 24-inch display on woot a few weeks ago for less than $100.00. So the entire project is less than $150.00 for a pretty great project that we will use for the foreseeable future.
@keen venture how long have you been researching 3D printers?
having a calendar is what we need the most
@abstract violet off and on for a while, but seriously for about a week.
@keen venture overwhelmed yet? XD
Yes.
@keen venture what are some of your use cases?
will both children be learning how to 3D print? / 3D printing something can take time, will the kids be okay with taking turns printing their models? etc..
prusa is a solid choice for the price range, but if you're looking to find a printer to fit your use case there are plenty of other options too
also depends on how much you want to get into the tinkering part of having a 3D printer
I would say just doing things with children that are fun to entertain and challenge my wife and me while making them more comfortable with technology. And yes they will be fine with taking turns. (They will both have to wait on me afterall . . .)
Cause I was thinking with that budget you could buy multiple smaller ready-built printers as a starting point ~
like get 4 of these https://www.monoprice.com/product?p_id=21711
I've heard tales that in the land of opportunity that libraries have printers
ive seen this particular model used in schools
@indigo jetty where is that land?!
Oh, that won't be an issue. I think that 1 powerhouse would be much better than 4 smaller ones.
Stillwater, OK has a 3D printer in the public library.
And OSU has one on campus that students can use.
@keen venture personally I think you should try start smaller and work up
Oklahoma State that is.
See how they like printing at the library
hmm I think I test this Project Prague out as for overlay and such https://www.youtube.com/watch?v=k38ygfiAqVg
Microsoft Project Prague, a part of Cognitive Services, is a cutting edge, easy-to-use SDK that helps developers and UX designers incorporate custom gestures...
And after I would buy one monoprice
And if you are still interested by Christmas (what's politically correct to say, "the holidays"?) consider moving up
I am actually aiming for the purchase around Christmas.
I'd say it f you asked everyone of us with printers do we use it as much as we thought we would we would say no
haha true
(except maybe the Ruiz brothers)
but they have multiple ones
Ruiz Prothers the 3D Printer farm
Your kids are at a great age for little bits too if you haven't already gotten them
good to start learning how to 3D model now 😃
Once the school year starts we have about 2 months of GO, GO, GO and then we settle into our family rhythm. I will consider the monoprice one though. With my wife’s job we can write off the cost fairly easily.
The Little Bits are amazing. We love them.
@keen venture 😄 there's a ladyada interview with littlebits
I think my daughter is about to outgrow the little bits though. Her grandfather already has her soldering.
My daughter turns the big 01 on Monday, I'm actually excited to do stuff like that with her
If she's interested when she's older
(or I'm still interested!)
That's awesome!
Get them programming and they'll take over the world
Thankfully both of my children have grown up with super nerds as parents 😃
@keen venture that's great!
I grew up with non super nerd parents and became one so it doesn't always work out that way!
@indigo jetty looking forward to show and tell 2025!
Haha
my local library does have a printer! which is a big part of why I can't justify it. I just... have to stop on my way home! it's an unreasonable burden 🙃
I got my daughter a charm bracelet for her first Christmas (it's in a frame) and I'm going to get her a new charm every year till she's 18. I wrote out on the back each year and I'll fill in which charm was gotten when
It was so weird writing 203X as a real year
I actually have a trellis top that I need to pick up
and start printing the other parts
my library actually has three: a LulzBot, Maker and Maker Mini (I think)
@elfin wave are there long wait times?
it's first come first served, so as long as there's a printer open you can use it. and you don't have to wait til it finishes, which is nice
when I went on monday only the mini was open, so it was just big enough to print one part of the project
what happens when its finished?
they put it in a box in the back until you pick it up
(printing https://www.thingiverse.com/thing:211447 )
http://www.youtube.com/watch?v=MW0JLxRgJ1Q
Trellis is an open source backlight keypad driver system. It is easy to use, works with any 3mm LEDs and eight tiles can be tiled together on a shared I2C bus.
Enclosure design features ports for USB and power. Bottom cover includes mounting holes for Arduino board. The tray piece holes the trellis driver PCB into place, allowing enough room for jumper wires. Snap tolerances are optimized for PLA, but should also work for ABS and SLS.
Great for MIDI instruments, drum sequencers, puzzle games and more!
Adafruit Trellis
a woman there said she printed a skull ring and someone else claimed it, which sucks
thats great!
they have a box of unclaimed projects. someone was apparently printing a 1:1 model of their head, which failed halfway through for some reason
I'm on my phone @elfin wave , what are the buttons in that item?
Oh ok
I don't have a specific use case for it yet but I really liked the idea and hey, now I have one?
Haha
the case has cutouts for a full size arduino; I'll probably be using something smaller than that but don't feel like messing with the design for my first project
An uno?
(shrug)
If it was me I would use something with USB capability
I should pick up a metro m0... get in on this
train
M0 does right?
Like that can emulate hid devices
So you can have a custom shortcuts device
can get other boards too @elfin wave , there's the feather m0, or the bluefruit feather
right! I might have it do a few things
I was thinking some sort of "game" too, where you're presented with a keypad and a screen and pressing the buttons makes things happen that aren't at all clear to you from the nonexistent interface
that, shortcuts, etc... like I said, having a 16 button grid sitting around that I can use for whatever I think of seemed handy, especially for fifteen U.S. dollars
// discord markdown code/syntax highlight test

int i;
SomeClass foo = SomeClass();

foo.bar(i);
}
hmm
int i = 0;
var foo = "hello world";
from time import sleep
sleep(1)
Foo foo = Foo();
no C++?
I think it should @ancient rivet reddit says it uses this: https://highlightjs.readthedocs.io/en/latest/css-classes-reference.html#language-names-and-aliases
uint8_t i = 0;
works with cpp
uint8_t i = 0;
not c++
cool. thanks.

I also started on my telegram learn guide today
terminal inside visual studio https://www.hanselman.com/blog/AProperTerminalForVisualStudio.aspx
@indigo jetty you gonna do a section for power?
powering projects?
yeah, i like the bits andreas touched on https://openhomeautomation.net/esp8266-battery/
not in this. but sleep is on my radar for a two minute tidbit video
(although i had forgot!)
what kinda radar are you building :O? @indigo jetty
its a whatever you want it to be light 😃
ah no, it will be controlled by telegram
So you will have the option to change it red green or blue
or chase clockwise or anticlockwise
or off
button is for sending a notification to your phone
really the neopixel ring could be any sensor or device you output to and the button could be any that you read from
@indigo jetty , cool ! Maybe the neopixel act as the decoder representing the alphabet by neopixel location and color, just an 💡.
not sure what you mean @minor spruce ?
oh display messages in code
B = Green pixel at 12 oclock
R = red pixel at 3 oclock?
Yeah, decode telegram... Haha...

So, due to the malfeasance and/or indifference to said, I am going to be looking for new employment starting Monday. Because I refuse to work for someone who is either actively involved in committing fraud, or unconcerned with the fact that they are the victim of said in their supply chain.
And I could really use hugs/words of encouragement right now because I'm about ready to crawl under my desk and cry my eyes out because I just feel so dammed betrayed.
sorry to hear that @bold turtle !
@bold turtle sounds like a shitty situation. The short term stress of changing job will be worth it in the long run!
Thanks @dusty citrus
Sorry to hear your situation @bold turtle
If it's any consolation, you are better off out of that situation rather than getting drag later on with heavy consequences.

grrr the FCC's ULS database doesn't have my ham callsign yet. I passed the exam last tuesday! let me broadcaaaaaaaast
@sweet fiber lets talk here
when I use linux its now arch
it has all of the benefits gentoo used to have, good docs, up to date software
and I don't mind not compiling
@sweet fiber I wouldn't even go django. I prefer flask
I'd do a flask backend that does the github interop that generates static guide pages
ah
I have heard of flask ... can't remember how it 'fit in' ..
ah ok so it sits in the python 'family' ..
its kinda the same role as django but much lighter
@stuck moth yeah I could get behind this .. I sense some overlap
😃
one test would be having a repo represent a guide and then that code rendering it to static html like we have today
is a repo-per-guide necessary? I can see the abstraction may prove crticial :/
but it seems a bit overkill ..
how many guides are on learn these days? I didn't see Phil's latest blerb in the AAE
~1200
yeah 1200 repos seems daft .. lol
repo per guide has the benefit of per guid epermissions
but makes it weird to share content
😃
same as gentoo's .. they use a force-push update system from git.g.o
it just makes PR's interface easy. The merging process is -slightly- more complicated though 😄 there's a Perl module for that .. 😃
@stuck moth any simple short guides to 'play with' ?
try picking something marked as featured
Are articles tagged or searchable yet? I Think I've seen a generic search somewhere ...
inconsistency. they'll be added back
I s'pose there's not a lot of difference between searching for "neopixel feather m0" and letting the text engine pull the terms out 😄
yup
yup I see the categories now .. cool 😄
@stuck moth What about a Jekyl like approach (of course, Jekyl is ruby...)
it's what github pages use...
it might be a potentially easier sidestep ..
ah, http://hyde.github.io/ is pythonic jekyll
sounds horrific .. stick to one language at a time ;P
hhehe
oh you mean a python -version- of jekyll ?
yeah .. I think if it were me .. I'd either stick solidly to ruby and move the existing ruby to new ruby .. or reimplement in a pythonic framework
but rails, I'd say was a bit overkill myself 😄
Advantage to Jekyll: essentially, every guide becomes a repo, and the guide works on it's own (hosted by github) , but can also be served up (and branded more) by Adafruit.
hmm .readthedocs seems to work ..
Advantage to Jekyll: literally cut and paste will just work well, authors don't need to do much of anything.
I wouldn't host on github .. I thinkg ladayada would shy away from that too ..
nor would phil tbf
how git'able is ruby .. ah well I S'pose if its jekyll ..
No, doesn't have to be on github...
and MD ftw too
markdown or rst is my preference
yeah, pick one 😃
you mean there's an alternative to MD .. who doesn't get MD .. lol
above link says RST beats MD.
.. besides Me.. but then I don't use RST .. probably never will.
yeah .. someone clearly likes RST 😛
I love markdown but rst handles structure and cross-referencing much better
oh does it .. -sigh-
TL;DR: "Writing for the web is what Markdown was designed for and where it shines. In contrast, Sphinx and RST were designed for writing documentation"
What's a guide? Is it Writing for the Web, or Documentation?
but this is web documentation 😛
Pick one 😃
yea then you're compromised by the other 😛
there are definitely structured sections like download links, pictures and product listings
When in doubt, look at your users (authors): Will they find it easier to craft a guide in MD or RST?
gah see .. too many bloody options ...
@dusty citrus yeah .. that's where I'd side with MD ..
especially newer (nonexperienced) users?
@dusty citrus right now the authors use the web interface which we can always back convert to whatever
yuk!
You expect 'pull requests' so 'end users' will see the raw stuff, ... not your web interface.
notepad++ for Limor, vi/nano/etc for everyone else 😛
@dusty citrus precisely ..
its gotta be clean, simple ..
limor uses the web interface for guides
dont tell me that's custom code too?!
-shudder-
isn't RST related to man page format?
its all html underneath but has a couple wysiwyg editors
If I'm a newbie at guides (but domain knowledgable about 'chip XYZ') and I want to contribute a bug fix/suggestion to a guide, which will be easier for me to add to: MD or RST?
I -hated- that ...
I don't think MD is extensible enough
Or am I wrong that that is your desired END goal to even make this worthwhile to discuss?
I think the guide text is the bit thats accessible .. the rest of the *** formatting should be handled by a template
so its less important what the overall layout looks like ...
because thats Taken Care Of™
I'm picturing Guides have repo with /code and /guide sections, yes?
so that /code is where project code will go, maybe an /images section?
my idea would be to allow continued editing through the webpage but back it with github
I can see @stuck moth 's issie though .. how w much extra info do you actually have to manually write ..
so you do want to host it on github?
so those of us comfortable with github can contribute directly
or only the project code? So guide text too?
I'm ok with github hosting
just mirror it on github .. I really wouldn't sell-out to github with their ever-changing ToS .. that's a recipe for disaster, imho
we'd use webhooks to mirror it to our server for serving
and I'm trying to talk gentoo out of taking that route ..
if you wanna use github, go Jekyll.... so that's MD.
I wouldn't serve directly from github
"oh just slap it up on github" .. yeah thats wonderful until github decides unilaterally to Go Its Own Way ..
the advantage is you leverage github hosting (until you don't)
as long as you have another copy why not use github?
hosting (if you're competant) is fairly trivial .. of course .. it you're not competatnt .. leverage those who are .. LOL
you can shoehorn travis in too .. LOL
#useallthethings
default Jekyll theme that looks Adafruit-y...
na, manual skin.
markdown isn't very extensible though
this is the other advantage of sel-fhost .. absolute control
@stuck moth how is RST by contrast?
I think you're thinking too complicated ...
it is extensible
you only need a basic framework for the text content
I'm thinking about the different block types that make up a guide
if you're going to outsource the whole guide creation (which is cool., don't get me wrong) you're looking at another tool
another user comment: "Unless you use RST regularly, Markdown is the way to go imo. I use both. Took me awhile to become productive with Sphinx. Everytime I go back to update something I have to figure it out again."
RST isn't as friendly. If you want pull requests...
right...
decide what your end goal is... design backwards.
I think we're straying from the KISS principles here ... 😉
which was why I was thinking of a simple framework 😛
we're not putting satellites into orbit here ...
yeah, I love markdown but it can't convey things like "include something from somewhere else" and "link to this product in an embed"
if you want to use version control, you need a markup language.
^ this.
You can't?
not that I know of with markdown
you just need a few custom tags, surely?
if you set the bar too high, people just won't come ...
how do you do custom tags in markdown?
hence the Gentoo problem .. quizzes and all that 😄
@stuck moth and that, together with the psycho who is the current sole recruiter, is why I'm not a gentoo dev 😄
ah interesting @dusty citrus
I've even met her irl, and spent time on Hangouts .. she certainly is ... Speshul 😃
wow I have one super-epic thunderbird crash backtrace going on here LOL
@dusty citrus lgtm 😄
you could then leverage travis/etc to check that the link-tags worked 😄
cool! that could work
I'm open to it
if you can convert our existing guides to it then its enough
https://github.com/waylan/Python-Markdown/wiki/Third-Party-Extensions (lots of potentially useful items there too. Maybe some custom Adafruit-y one that links to product ID, for instance
if adding a markdown link to an Adafruit product was just [Adafruit:3333]
and that autolinked to https://www.adafruit.com/product/3333 (and grabbed the title, etc)
Please note: We're still adding full support for all of the cool sensors to MakeCode/CircuitPython/Arduino. We recommend using the CPX with MakeCode only at this time (it does work very ...
or fancier embeds: https://learn.adafruit.com/gemma-m0-sheikah-pendant#parts-and-components
yeah that -should- be mostly doable .. but needs some smart templating to make it Simple ..
I can already see the Lean site is getting cluttered ..
learn*
Yeah, most of that is either markdown-ish now, or would be a special case
right ^
the individual guides have a bit of commonality with the likes of instructables, etc
which are quite clear
Yeah, Markdown wins, I think.
And keeps it really clean... worst case, won't render without an extension.
and allows folks to easily submit pull requests with clean text changes.
you can't expect everything to render without its host framework .. you think Facebook are using offline WYSIWYG editors? oh hell no ! lol
that's why all these tools have the facility to host the framework baked-in 😄
You expect users to edit 'raw code' and make improvements.
so it needs to be 'mostly' readable.
hopefully it won't be the raw code . or the framework .. just the editable/dynamic/variable content of each guide 😄
which you can slot into whatever framework you create 😄
raw editing is nice but ideally it'd still work through the learn system
it's code, it'll all be mixed. Needs to be simple enough.
right
@stuck moth I was picturing someone grabbing a copy via git, editting a text file of 'guide', and making pull request.
@stuck moth theoretically if the syntax is simple enough, you can lash up a simple new 'Learn create' interface for the non-techie people .. everyone else will just Get It .. [hopefully!]
@dusty citrus precisely!
if I get code and guide at once....
yeah, I'd love to be able to edit it directly
git checkout adafruitprojectX
I can submit a guide improvement or tweak the code... and git pull it all.
yup, not everyone knows/loves git though
you could, theoretically, have git checkout learn.backend though .. I would honestly keep them all separate
well .. I thought we were talking about github here?! 😛
nano guide, "If the above doesn't work, try XYZ"
it has no pointy-clicky stuff 😄
there is a tortoisegit interface .. does it play nice with github?
tbh, I find it faster from a command-line though
they all play nice with github 😃
well sure .. git push, voila! :
and Github Desktop puts a mac spin on it, for example.
so thats the challenge 😃
Hmm, Atom would do it all.
An Atom AdafruitLearn Plugin
git support, markdown, the works.
cross platform.
One stop shop
yup yup
And you'd only have to support the keybits for adafruit, leverage all the rest.
yup yup
Average user could easily click to 'edit the guide' (if code and guide are together, they get it all...)
They find a mistake, they add a correction (That's Red, not Blue... don't cut the blue wire!!!)... and commit, and PR
If they find mistake in code, exact same process.
👍
code and guide in one place.
so easy to keep updated.
And if they take to a new place, they can fork the whole thing...
I'm thinking of the POIs guides as a perfect example.
There are 3-4 guides, built on the base, and now that code has all of it in one repo...
It would be great to be able to submit corrections to guides!
I know I'm late to the party. But there have been a handful of times I've noticed a typo/grammatical error.
@elfin wave there is email feedback but no way to edit it directly
oh Atom .. yes, that nighmare LOL
.. good old Electron .. we were having a discussion about that in another Discord LOL
but sure .. in principle .. 😄

so is there less lag on voice?
Well, at least the robot's trying.
Hah! Thanks for sticking up for the clumsy robot, @runic elbow (It's really incredibly good, but it shows how much the last 1% precision in walking / object placement / limb use matters.)
it's the falling over at the end that gets me
I admit I laughed hard at that. It's so human in failure and humiliation. :>
I have my ham license!! KD2NZQ
alas, I have a group D license (2x3, 2 letters, my state number, 3 letters). probably because there are so many people in NYS that they ran out of the 2x2s.
it was a mix of "not as bad as I thought" and "harder than I thought". the test itself I got didn't have much of the stuff I was weak on (antenna design, etc)... just one question about decibels that I had forgotten to study for
😱
Yeah, I feel like I'm drinking from a firehose of electronics and radio wave knowledge
luckily for me I don't really ever need to worry about SWR, etc... I bought a $25 Baofeng 5R on amazon and that should do me
@polar wraith hey m8, did you say you had a macro lens for your DSLR? (cant recall) -- if so which one?
@abstract violet I need a macro lens for the DSLR....

sure does
how are you?
great, thanks
😃
Look at all the onion I got from a single onion bulb!
how did you do that? did you split it somehow?
I don't know. It just grew like that.
I knew these onions were supposed to multiply, but this is a little ridiculous.
They are good for a lot of stuff.
I like to put them in sour cream for peirogis. A word I can't spell.
I have chive and rhubabrb. And a spider plant.
I learned that chive is almost indestructable when it comes to weather.
I also have some small pepper plants but who knows if they'll get enough heat here to ripen
wow! super hardy
😃
Eh, maybe tomorrow. I don't have the stuff needed at the moment.
Or maybe I could take the soil from the onion I picked and put it in a plastic cup.
for a new spider plant?
heh, that'll be a jungle
Yep.
Spider plants all over the place in probably little over a year.
Or however long it would take an army of spider plants to grow.
I can't imagine its too long
Probably not.

Is it possible to change the start up noise of Windows 7? Or is it one of those things that require hacking the operating system?
Thank you.
ogredrew, 3dprinted case, with thin enough top (or extra thick there?) that drink pushes on button(s), to make it light up.
I wonder if the temperature sensor could help too. If you put a hot drink, it lights up redder, a cold drink, it lights up bluer?
This sounds like a great CPX project: Circuit Playground Coaster
I wonder if you could detect the drink getting empty.... and have it shout for more.
@dusty citrus hrm... semi-thick ish translucent on the sides, with maybe a plexi insert in the top. buttons facing down so they're still accessable, with reflective stuff on the bottom to make light bounce... not sure how much you could get out of the termal sensor, but a pressure sensor to detect weight of cup would be a reasonably easy add on, pure analog logic I think...
I'd do it lights up, make the drink push down on buttons, much easier.
someone did a case, where the CPX button were pushable. I think if you did it with Flex, it would be water tight still, but still allow pushing down on buttons.
TIL there's a mini HDMI and a micro HDMI standard.
I discovered this when the mini HDMI cable I bought on Amazon didn't fit into my camera.
yup, small and smaller.
Yeah. 😄
Luckily it works for the Pi Zero, so I'll just pretend that was my plan all along.
You can get an adapter, but likely a second cable makes more sense.
Yeah, I ordered a micro today

It's about 150km West of Dublin and 100km east of Galway (I work in Galway)
It's considered the center of Ireland
@abstract violet picked up a macro lens today 😂
@indigo jetty I was actually thinking of just using my phone too!
Brian L, I see it now, sort of mid M6. Very different scale from (my part of) Canada; we went up to the family cottage recently and the drive is about twice the distance across Ireland. (Dublin<->Galway at least.) That doesn't even get us out of the southern part of the province of Ontario.
nice keychain btw

@indigo jetty !! I'm glad it went well! And yeah -- hard to really keep your thoughts still when you're playing the waiting game
I do @abstract violet I'll try it out for you either later or tomorrow

depends how fast have being typed
it kinda stack them together so only need one avatar there if it come from sameuser in small period of time
I used the option to never display avatars. A few weeks back.
@dusty citrus like IRC style?
Janisku7: yes, I think they used that term to offer it.
It's hard to argue with #IRC features because it has been in use continuously since 1992 or so, and so has experienced a lot more evolution and improvement than most chat protocols.
UI, security, protocols, and many other aspects.
appearance: compact.
We used a *cough* secure server similar to IRC. Can't recall the name of it.

The truth is to be found in oatmeal.
is a Canadian of Finnish heritage, so is celebrating both.
Is today a particular day in history?
which part of canada @midnight perch , east coast?
No, I'm on the Great Lakes in Toronto.
nis: No, Canada Day is the anniversary, on 1 July.
Finland's independence upcoming on 6 December, unless Janisku7 tells us otherwise. 😃
Let's see .. camelids (llamas) migrated out of S. America across Alaska to the Gobi desert; humans migrated in the other direction.
Haha. Yeah the 'at the same time/place' assumption is a big one to watch out for.
Camels are different enough from llamas that I'm going to backdate that speciation event quite a bit. 😃
I forget how the other camels got to the arab world, but first stop had to be Mongolia (or near there).
The only thing I remember is that while they migrated west, so many other species migrated east through beringia.
There are camelids in Australia too. (I just learned.)
Oh, they are feral.
The family diversified and prospered, but remained confined to the North American continent until only about two or three million years ago, when representatives arrived in Asia
^^ Wikipedia.
All that by way of understanding prehistoric human migration in northern north america.
I'm drawing a blank prior to dorset culture.
As well you should.
You mean, who were the people who became the PaleoEskimo?
Because before the Dorset Culture I don't think there were humans in the Arctic.
Hence the blank. 😃
I wish we could ask them. 😦
There's another group, I thought. Maybe not. There was a whole thing about which direction (east to west, or west to east) crossing the N Atlantic.
Lots of speculation, like that thing recently indicating humans had been here in N. America 130,000 years ago.
Easy to find hints that suggest something is worth looking at, but hard to prove anything like that.
I'm sticking with the ~ 16,000 YBP migration during the last interglacial.
Definitely. I lived very close by the Clovis dig, and didn't think to visit or inquire.
Oh neat.
I used to stop there on my motorcycle. I assumed it was off-limits so I never walked in the .. 100 or 200 yards to see the site itself.
Area where I live has been heavily invaded and recolonized repeatedly, so it's hard to go back much more than the group before the modern Native inhabitants like the Mississauga.
There's a very large amount of unused land near Clovis. If anything, cattle might have grazed there in the modern era -- no human artifacts from recent (post-European migration) period, for like, 2-3 km at a stretch, there. It'd be surface stuff like irrigation equipment.
Today, maybe more developed, though.
I'm remembering now. This is New Mexico?
Yes, it's about halway between Lubbock and Amarillo, and say 60 miles west of both.
It's on the state line.
Arid section, if I recall. When I visited Texas someone told me it hadn't rained in Amarillo in 2 years.
That's probably good for archeology. But how did people without irrigation live there?
Heh, also good for motorcycles. 😃
The site itself is part of an ancient runoff basin or something like that. It does snow there! I've been caught in thunderstorms, too (I remember the hail rather specifically).
Irrigated by flashflood then. Yikes.
I guess that would be a lot better than permanent desert.
Where do you live now, nis?
I'm in Connecticut. It's 73W and 41N by ICBM standards. 😉
Which is important, because you drydock your missile sub there.
er, subs.
Not helpful to have only one. 😃
Yeah, on the hilltop so 'the' tsunami won't get it.
We go from 600' to 1100' or so, around here, in elevation.
There are lots of 400 ft ascents by bicycle. I've done up to 1350 ft. per day.
passed through Groton, down on the coast, but has not much other experience in CT.
(Can't go continuously uphill, though, to make it to 1350' in a day).
Hence my submarine comment.
Hehe. I was in Groton on Tuesday.
It was really annoying to try to use Google Maps to find the Wal*Mart there.
I finally concluded we gave up too soon and that it was necessary to go around to the back of the only apparent shopping center. And there it was.
checks if he's still offtopic. Hahah.
That joke never gets old. (It was always old.)
I was explaining Penrose's Andromeda Paradox today, to a friend.
https://en.wikipedia.org/wiki/Rietdijk%E2%80%93Putnam_argument
Always old is a very interesting concept.
Well, I have a pretty self-centred definition of "always". Like, the primordial lithium was always old.
If it's fairly constant over your own lifetime, that's a pretty decent working 'always'.
@dusty citrus interesting concept indeed! makes me think of quantum physics ~
The Andromeda Paradox only makes sense to me if the car is driving very fast. It isn't immediately obvious to me how it occurs unless we are talking about people walking down the street at relativistic speeds, or events that occur sub-microseconds apart. Is there some amplfication due to the 2.5 million light year distance to Andromeda?
Huge amplification, yes.
but even the slightest movement of the head or offset in distance between observers can cause the three-dimensional universes to have differing content
Simultaneity starts with two lightning strikes equidistant from a moving train (say, just north and south of the train running on a n-s track)
Einstein asks what the difference is between the person on the railway carriage (moving) and the one on the embankment (train platform).
His book "Relativity" is worth a read. Written for a general public audience.
So, a plane of simultaneity is the set of all events, 'everywhere' that are happening 'now'.
The train thought experiement works fine for me.
I think Penrose suggests that at the distance of Andromeda, that delta-NOW can be a full day in length, for very low relative velocites between two passing (proximal) observers.
The implication seems to be that two very different moments in time may exist .. simultaneously. 'NOW'.
I could have that wrong, as I suspect Penrose doesn't believe it himself.
That's why it's a paradox; it's trying to tell us something is wrong with special relativity.
But I guess my failing is that I always imagined the train as a normal-size train going a relativistic speed, never as a million-light-year long train.
Going normal speeds.
That andromeda argument makes no sense to me.
Right right right right right.
rofl million ly long train!
doesnt light year measure time not distance? -- very time-lengthy train?
scruf, I pay attention to it because Penrose has brought it up more than once in passing.
It's not a paradox though... it's merely requires allowing perspectives to see different things...
A light year is the distance a photo travels in 365.25 days (or so).
if you and I stand in slightly different places, I might see something you can't see, right?
An AU is the earth-sun distance. Solar system radius is 40 AU.
just used to hearing/using AU over ly
An AU is only 8 light minutes.
extending that perspective to light years lengths, of course we'll see different things.
They are different by a factor of ~63,000.
Robert Burnham, Jr. has a great write-up of these scales of time/distance.
nis -- photon not photo. 😃 I know you knew that.
plays a game called eve where AU is the standard measurement of distance
photos contain more than one photon 😃
Except very bad photos, yes. 😃
Hehe. Google this:
burnham galaxy size of north america

Turn to Chapter 2 on Page 13 "We are beginning a journey"
scruffynerf: "see different things" is clear and non-paradoxical from the train thought experiment.
nis: I'm planning a solar system model in which the speed of light is a moderate walk.
So the 1 AU takes 8 minutes to walk, in no particular hurry.
okay, that works well.
I have one for the age of (any type of) life on earth.
Basically the child is 4.5 feet tall. Her sock line (above ankle) is where life began; her height being the age of the Earth (4.5 billion).
Thickness of her scalp is generously mapped to the existence of our species.
hah!
;p
I haven't thought of that one in a while. I think it's correct.
Bacteria only from sock cuff to eyebrows, I bet.
When you get right down to it, life is basically about the bacteria.

yeah, I don't remember where multi-cell orgs arise. 560 mya I think. Maybe earlier.
One model I actually made starts with the Sun as one of those big exercise balls you can sit on or do pushups on.
Sun diameter == 60 cm
Hehe. I'm way off. That 560 mya event is ...Cambrian explosion
You can't do much with the interplanetary distances but it puts both moderate asteroids and Jupiter within the range of things you can touch.
(Fine talc for most asteroids. Fine sand for big ones. )
Well eastpole I think the big whoa for the layman is that Saturn is so much further out than is Jupiter (which ain't too shabby in its own right, so far as distances go).

I think the Earth vs. Sun size is also a revelation, but that might be because I mostly do this model with primary school kids.
The interstellar distances I do with planets strung out along a 10 meter rope. Yes, inner solar system vs. outer solar system gives them some scale whiplash. 😃
Burnham has some good scale models in that passage. Every time I reread it I re-remember where I had it wrong. again.
Er, interplanetary ^^ not interstellar.
