The transmission of television signals to devices in motion ("watching terrestrial broadcast television in a moving automobile") takes on additional challenges, besides those of just transmission of television (signals) to stationary receivers (your house).

Imagine a flying robot in the form-factor of a basketball, that in the gymnasium next door to a pro basketball game, moves exactly as the ball in play in the other gym does - in real time.
All the spinning in particular, in this case.
Imagine the special reception problems it would have to deal with, to be commanded remotely.
For example, using infrared light as the controlling signal set.
🛩
Kind of like a flying R2D2 - sudden spherical movements about a centre.
Or the strike ball of an IBM Selectric typewriter.
The robustness of such a signalling system is critical to events in the near technological future.
I think for a lot of applications, this signalling system is going to be optical (OWC) rather than RF based.
Mobile Digital Terrestrial Television is probably going to be an ongoing source of this technology.

Ham radio operators working with handheld transceivers know from experience how moving one inch to the left or to the right can cause severe signal degradation.
It's pretty amazing how big a difference an inch or two can make.
I don't use handheld cellular enough to have a feel for this same problem as applied to either voice or data communications using cell phones.

yo @dreamy solstice YOu are holding the second best macbook pro released by apple, ever, imo
dreamy solstice

I have the last 2012 version of that laptop, and they are amazing.
The keyboard is fantastic, the build quality is great, the size is wonderful, the ports are modern enough to still be usable today without any effort, and TB2 is still a beast of a port.
I recently found a refurb of my current laptop a few years ago, and I am saving it for when this one dies. It's that good.
The MB pro 2011, I mean
2011 - 2013 was golden era for MBPro, and with a built in GPU, it's just a great daily driver.
I even game on mine, and I am more than satisfied
dreamy solstice
I game on my mbpro
it runs starbound at 60 fps
starbound runs on my year old hp gaming laptop(that runs no mans sky at 20 fps in 40) .. at.. uh.. 15 fps
I am incredibly impressed by this macbook
and it's the second apple product I've ever owned(first was an ipad 4)
grave crest
@main kiln I have used a late-2013 MBPr i7 + 512gb ssd + 16gb ram + GPU for the last 5 years. And it's a beast.
It's a bit heavy to haul around, the trackpad it getting a bit wonky, and the battery life was never something to brag about. But 5 years later, it still handles 95% of what I throw at it without a single complaint.
main kiln
So you raise a point that I have never found to be something I notice. Heavy?
I guess I always have a 35 pound backpack, so I don't notice 10 - 15 pounds +-
grave crest
the 15" version is a bit heavy for me -- I also haul around tools for work, so the extra weight + adapter I feel rather easily. Compared to a regular Macbook that is.
grave crest
It's not as heavy as my ancient IBM Thinkpad T43p
[which was a beast back in 2006 with a single core 2ghz Pentium 4 + 2gb ram + 7200rpm HDD]
But seriously, the 2011 MBP you have is a very awesome machine. 😃

I almost like it more than my hd laptop

@dusty citrus Specs, for your computer.

oh if this is the 80 dollar one (sorry I'm reading about the M4 hardware released during the show, very distracted) ..
that's a Dell Optiplex
had 2gb ram I bumped it to 3GB I think
I think it's an i5
it's weeerd cuz it has VGA out not HDMI
2012 vintage
Intel(R) Core(TM) i5-2400S CPU @ 2.50GHz
The OptiPlex form factor is ten kinds of awesome
it's basically a professionally engineered Mini ITX system.
and he threw in a good monitor that does picture in picture from Dell
and he threw in amplified speakers
and he threw in keyboard and mouse and all cables.
and he asked 60. I gave him another 20 (I forget what I said as I did so)
"and here's the keys to my Mercedes" was probably going to be the next thing out of his mouth. ;)

trellis m4 on the way. ;)
decided to try the skinflint and do US Post Office First Class for 5 bux
There's a Dotstar singleton somewhere but I haven't found it.
So that's at least 97 LED's on that board. ;)
60 mA x 32 NeoPixel is humm...
That's 1.9 Amperes. Haha.
This is good for me, because without any soldering, I can hook up the Fried Circuits USB thing and get an accurate measurement of the current draw at various loads (LED's lit to varying PWM strengths) and get a handle on the (ongoing) conversation about 'How much power? '
I'm expecting perhaps 3 mA per LED for practical uses around here.
3 x 3 x 4 x 4 x 2 = 288 mA which is still a lot, really.
The 3x3 is the RGB of a single NeoPixel multiplies by 3 milliamperes (equivalent) of DC current.
The 4x4x2 is the NeoTrellisM4.
dusty citrus
The PWM of many leds in a strip is not synchronised. They do not switch on and off together, so the power supply does not have to supply the full current at any point.
from:
If you're using Trellis M4 Express, you can go to the next page cause there's no pin 13 LED - so you won't see it blink.
The Trellis M4 Express is protected by a Positive Temperature Coefficient device (PTC, aka polyfuse) specified as 500 mA.
I do not see a Trellis M4 in the Arduino IDE after (what I thought was) a careful update of the board support packages available in the system.

the offset cam and the rotation will treat each dotstar as a double pendulum, which under inertial behavior would be chaotic, under constant rate drives will be a spirograph, given the many dotstars on the plate and an appropriate pair of speeds, the pixels will compose overlaying graphs that should fill in most of the space; as well many of the grid positions on the plate will be redundent, and can be eliminated to reduce mass and processing time. Then carefully tune the update frequency you drive the dotstars at and it'll have the effect of being a 'large' display of on-grid pixels at a great density

So I can just barely fit the Trellis M4 sandwiched between two perfboards.
I've got it rigged now so that one piece of perfboard acts as an actuator for the RESET switch, making it a lot easier to operate, and keeping finger oil off the elastomer landing pads (I don't have an elastomer keypad yet).
I've reprogrammed it in both CircuitPython (see #circuitpython-dev today) and in Arduino IDE.
The whole thing wrapped in a thick pink antistatic bag, and rubberbanded. ;)
I can see 5x4 NeoPixels clearly; the others obscured by the perfboard.
DotStar is underneath, and I can pick up on it -- that its changed colors or blinked.
Or just flip the whole thing over to watch the DotStar (good visibility).

3D printer is now in the state. Fedex can do one of two things:
-Deliver it tomorrow.
-Hold the package for one day and not move it at all.
So let’s see....
I can’t imagine they’d deliver it before the estimated date
jaunty jetty
I guarantee you it was allocated on a truck before it got in the state
logistics is all about predictive scheduling
old fjord
Allocated?
old fjord
@jaunty jetty Upon further investigation it appears fedex home delivery doesn’t deliver on Mondays. So it’ll probably be ready to deliver tonight, and will go out for delivery Tuesday morning.
jaunty jetty
logistics is all about fitting everything together as dense as possible to make the most money out of the work that will happen regardless
tetrising boxes onto planes, planning full trucks for delivery, slower delivery speeds cost less because you're giving fedex a larger period to figure out how to fit your package into their plans
conversely next day shipping costs more because your package will for lack of possible combinations, be less optimal and consume more of their resources
dusty citrus

No copypaste foo. ;)
Well, except housekeeping stuff. Not quite the same as not using any sources at all; I had for example a useful Makefile that I borrowed from.

real anvil
the display thing is really cool but that's wayyyyy too much work for a 7-segment display, imho 😆
jaunty jetty
a mechanical display of that size would cost hundreds of dollars, and a lighted display of that size would not be simple to make
real anvil
oh I won't/can't argue that 😄
...parts are cheap, yes, but then you factor in time and there goes your savings 😏
jaunty jetty
btw, anybody who has the capacity to produce a simpler mechanical display of that size for like 30~50$, there's your million dollar idea
servos would work, just need to make it out of good wood or metal, maybe both
real anvil
I'd just assume 3D print one and tape LEDs inside...but I love LEDs so that's just me 😆
jaunty jetty
you'll need a bunch of LEDs
real anvil
servos would be awesome. has anyone designed a flip-dot display I can 3D print yet?
jaunty jetty
I'd say at least 5 per segment, but 30 would be better
real anvil
depends how bright you want it
jaunty jetty
the rough part of making it lighted is you'll need to use mosfets to control large collections of LEDs to get uniformity and brightness
I guess maybe neopixels
real anvil
someone designed a lighted 7-segment display and used neopixels. it's on thingiverse
looked pretty decent and I think he only had one LED per segment. not sure how it'd work in a bright room, though
thin canopy
real anvil
but to do something the size of what's in that video above I bet you'd need more than one per segment for sure
LEDs are fun 😄
jaunty jetty
this project lists a 100$ spool of neopixels, I think there's a better price on Adafruit that will work
also suspiciously all the photographs are in not particularly lit spaces
I think you can do single color LEDs on mosfets for less than neopixels at a better brightness; neopixels have a lot of advantages but brightness is the prime concern; if it really takes 100$ worth of them to get a display of this size that is not easily visible in a well lit room, I don't think that's going to work
it's a lot of soldering but typical 5mm 'super bright' white LEDs are running a hundred for 72 cents, you could put a hundred in every one of those segments (except the punctuation) and depending on how this is going to be used that may be a good plan
the million dollarness of the idea is making a product people will buy at a substantially lower price than the exploitative products currently on the market
with the servos, the mechanism is trivial and extremely robust, the difficulty is fabricating it, I don't have anything you'd need to produce a rugged display with all the parts attached securely
real anvil
get some magnet wire and make seven powerful electromagnets...then, flip-dots! 😄
jaunty jetty
in all honesty, yea
the less and simpler the moving parts can be the better, so if you used an electromagnet with a permanent magnet instead of servos, it would be more durable
I'm thinking find some cheap small bearings, figure out how to make cheap small pillow blocks, the shutter is a plate of sheetmetal on a shaft, mount a magnet in the shaft somehow so it's north and south poles are perpindicular to the shaft, put that section of the shaft in a coil, that should be relatively inexpensive and very robust
if it's strong enough you could use much weaker magnets to latch the shutter open and closed
real anvil
true haha 😄

Wow that’s impressive
I think it’s cool how amazon will say how your package was delivered.
So, “Handed off Directly.”, “In Mailbox.” “Near front door or porch.”
Does it require USPS to have new technology?
jaunty jetty
you probably don't get a ton of tracked packages from USPS that aren't involved with amazon
jaunty jetty
ebay is fine, but paypal can go look at a rock
old fjord
eBay is not fine from an objective standpoint.
They have so much fundamental stuff to fix.
They take a huge percent from sellers and they’ll always side with buyers. Makes it a bad place to sell.
jaunty jetty
terrible is the norm
old fjord
And every time a buyer gets scammed the scammers get the money from the buyer and eBay has to pay the refund.
So scammers get rewarded
Those are just two issues.
jaunty jetty
pick another platform and there's a list just as long
I don't have it in me to be angry at everything always
old fjord
Well I definitely have my preferences
One difference between AliExpress and eBay is that the sellers get paid by AliExpress after you confirm it was delivered.
So if you get scammed AliExpress issues a refund and the scammer gets nothing.
I’ve never ever been scammed on AliExpress.
jaunty jetty
sounds incredibly easy for that buyer scamming you were talking about
old fjord
Disputes require photo/video evidence.
And an explanation. They’re checked by AliExpress.
jaunty jetty
that's untennable
sweet mango
@old fjord I think you have a AliExpress problem.
old fjord
Nah
jaunty jetty
they do now, what about when they grow 10%
old fjord
Alibaba is one of the largest companies in the entire world
I think they’re doing fine
jaunty jetty
you know what I mean
old fjord
Well you said that them checking every buyer dispute is “untenable” They’re obviously doing a fine job. Just the fact that their policies support a scammer free environment probably eliminates a lot of disputes.
There’s also lots of competition so one negative mark on a seller can really hurt a seller. Thus they try their best.
jaunty jetty
untenable means "cannot be continued"
old fjord
I know what it means
jaunty jetty
then what does your statement have to do with anything
"they're doing it now" is irrelevant
old fjord
Um....I was explaining why it’s sustainable and CAN be continued.
jaunty jetty
no you weren't, you were stating facts about the present
old fjord
Well the PRESENT facts show that the buyer protection is indeed sustainable.
jaunty jetty
if aliexpress continues to grow as a service americas are aware of and make use of, they will very quickly not be capable of maintaining this
present facts cannot show anything about sustainability

@dusty citrus I fixed my macbook
turns out, having a dead trackpad.. messed with the keyboard somehow
replaceing the trackpad, also fixed the keyboard
jaunty jetty
was it having a dead trackpad that messed with the keyboard, or having no trackpad connected at all
dreamy solstice
no trackpad at all
the ribbon connector tore
so I had to remove the trackpad entirely
I kinda think the trackpad and the keyboard where on the same circuit
jaunty jetty
something like that; laptops are never designed with consideration for integrated hardware just not being there, and apple doesn't go the easy route of the trackpad being a USB device
dreamy solstice
yeah.. apple is weird
but luckily I had an old 2011 macbook
so it was.. really ungodly fast, even today
but still user servicable
jaunty jetty
the macbook was fast or the shipping was fast?
dreamy solstice
the macbook was fast
it runs starbound at 70 fps, and that game can make even the mightiest gaming pcs cry a little
jaunty jetty
having spent a year with a 2010 macbook air, I agree/disagree, it is of course complicated
dreamy solstice
well,, the 2010 one had a core 2 duo
jaunty jetty
it's not even that the laptop is fast
dreamy solstice
my 2011 macbook has a quad core, 8 thread 2.3-3.6 ghz core i7, 8gb of ram, 1gb radeon gpu, 7200rpm hdd
jaunty jetty
the macbook airs have always been designed with the computational weight of about three sheets of paper, and that laptop could drive 3 displays ranging between 1080p and 2K at the same time with multiple windows on each, multiple desktops on each, and lots of stuff happening in most of the windows while streaming compressed video from 15 security cameras separately composited into one window
dreamy solstice
yeah.. the macs are insanely fast
jaunty jetty
power is not Apple's solution, obviously power is needed for many tasks, but macOS just runs way better on it's hardware than windows does at all
I'm too deep into windows on my own time, but macs are really good for a lot of stuff
dreamy solstice
yeah, apple is the master of optimizing stuff
jaunty jetty
I really think their obcession with things being optimal is something most developers need
like, on the iphone, if your app isn't a videogame and demands the processor be elevated for too long, iOS kills your app
you have to make apps highly optimal, or they just get terminated

most of them are powered by DisplayLink chips, the devices work fine but apple messed with the software situation https://www.displaylink.com/products/usb-adapters
macos 10.13.4 to 10.13.6 works with problems, it basically has to present the adapter as an airplay target on a virtual network connection, and then stream the video over the virtual network to the USB device, which means the image quality isn't perfect and there can be display lag

PC3-10600 - 24 GB registered - ECC
PC3-10600 - 8 GB registered - ECC
the ram was pc3-12800
so it wouldnt turn on after putting the new ram in
so I put the old ram back in
and it still wont turn on
everything else is still plugged in (like psu connectors, sata etc)
I didnt unplug anything inside the computer
yet it still wont boot up
what do I do?

That RAM should work regardless of the speed difference, since the host will just run the memory at whatever speed its capable of. Try clearing the CMOS?

ooo, OSH is getting flexible PCBs
they're not available yet but that sounds all kinds of exciting

Now my cat is playing with a zip tie.
karmic kite
yep
some devices actually have a button to do it but popping the cmos is the fastest way
dreamy solstice
I'll try that later then

@dreamy solstice what mobo do you have?

If you yank out the main battery (the one designed to be swapped out by the consumer, routinely, without tools) you can then put a pair of tweezers across the coin battery's terminals (having removed the coin battery).
Count to a few mississippi's and then put the battery back where you found it.
The idea is to drain any small caps that may be holding up CMOS (keeping CMOS supplied with a useful voltage).
The system should be designed to read the values stored, and notice that a critical value is way off (probably set to zero or 255).
Then it will initialize all values in CMOS from a table of defaults that it stores in ROM.
It's nice to have a print-out of what they're supposed to be set to; when I get a new computer, that's early on the list of things to archive (and store in the new box the machine came in): what the CMOS settings were, as shipped from the factory.

@fluid forum I dunno, the dell PE t310 mobo?

I take that you got it sorted out?

Good idea

Never know when you will accidently build an interdimetinal portal

wanna know one benefit of having a laptop with a metal case that gets really hot(the cpu itself gets to 66 celsius, that spreads out across the case)?
fluid forum
Nice in winter?
dreamy solstice
yes
my macbook has a metal case,
that gets pleasantly hot
I can just hug it when I get cold
dreamy solstice
oh I have a cat alright
my macbook is just more efficient
wanna know why?
because it doesnt try and run away when I grab it and hug it
fluid forum
Lol
dreamy solstice
my cat is actually... very tollerant of most things, but he still dislikes physical contact
I could probably squeeze 60 seconds of cuddle time out of him before he whips out the claws and teeth
longer if I just came home from a long weekend at my grandma's

@old fjord this might interest you, text to speech in javascript https://itinerarium.github.io/phoneme-synthesis/
dreamy solstice
ok so
popping the cmos didnt work
what's weird is..
the power button wont light up
or even register any button presses
jaunty jetty
so it's dead? totally unresponsive, no signs of life?
dreamy solstice
oh the psus, mobo leds, status lcd, and fans turn on
even the disk drive makes that clicking sound it makes upon turning on
I think the power button may be dead
jaunty jetty
is it plugged in correctly?
dreamy solstice
yes
jaunty jetty
that header tends to have a lot of pins that won't be used, and the LED in the button needs to be attached the right way around to light
karmic kite
the power button
dreamy solstice
oh, I cant access the power button
I'd have to literally break the case in half to get to it
jaunty jetty
what computer is this
jaunty jetty
on the motherboard
jaunty jetty
the power button plugs into the motherboard
dreamy solstice
ok, I dunno where it plugs into the mobo
this is the server
the panel currently visible from this angle
that's the only removable panel
besides the front cover
jaunty jetty
dreamy solstice
wait that's the t30
I have the t310
that's what the mobo looks like
the immediate noticable difference is the 6 RAM slots
jaunty jetty
hard to tell at this resolution but check the label on that port bottom left
dreamy solstice
ok
jaunty jetty
while you're at it, just reseat all the connectors and check for dangling plugs
server troubleshooting step #1, reseat all relevant connectors
step #0, disconnect mains power
so the T310, like many server class machines, does not have a specific motherboard that is associated with the entire line, and as such none of this documentation goes into useful detail about the motherboard beyond common features like iDRAC
I can't read anything in that image beyond DELL
there are in my expert opinion 2 things that could be the system panel connector, which dell has helpfully deviated from the norm on, it's either that little connector at the bottom left, or the black connector in the middle, just to the left of the white 24 pin and 4 pin power connectors
I'm used to working with companies that don't make themselves a problem by using custom platform hardware, every server I've ever opened had a standard ATX system panel header.
dreamy solstice
ok, back.. also I got it working
the power button connector was completely unplugged
karmic kite
and is it running now?
dreamy solstice
yes
karmic kite
noice!
dreamy solstice
unfortunately.. the 32gb of ddr3 ram I had was 1600mhz, and the server mobo only supported Up to 1333 mhz
so I'm stuck with 4gb
and the 32gb is registered ecc
so it wont work in normal pcs
coughs
that sucks

Linux will generally run better on any given hardware than a commercial OS will.
(NetBSD even more so, as of several years ago when I was using itt)
NetBSD had a rep of running earlier and better on newer hardware than almost anything else.
Their team was very proactive on coding necessary hardware drivers, sooner.

That’s cool and all,
But how do you have that much free time

but why
jaunty jetty
because enjoyment

Computercraft is a pretty cool mod.
silver shale
i used that before, it is cool
sweet mango
I love it.
jaunty jetty
it's cool but Lua is hardly suitable to doing anything complicated
you can build a crane out of dinosaur bones, but bones aren't really good for it

idk i built a sign with it before, somehow i can build a sign in many sandbox games, but somehow i did not actually build one irl

I created a battery management program using computercraft. If it detects that a battery is 5% lower than the battery with the highest charge, then it balances all of the cells.
jaunty jetty
that's not complicated
sweet mango
I took me forever, because I have never done it before. 😆

all i did was have a program on a loop displaying images then clearing screen after each image

Oops, I am getting distracted again. Well, time to go finish writing my four page rough draft essay for college. *Ugh, essay.

I was working on a system of turtles that would automatically expand the GPS network and build mystcraft portals to send mined resources back to base as well as stargate turtles back and forth from worksites for refueling so they could slowly consume the world
lua was the main problem in this since it made any kind of telecommunication very difficult to work with in code
sweet mango
Now I really want to go play with computercraft. Oops, I am distracted again, dang it. 😆
jaunty jetty
here's how you break the game using mods https://i.imgur.com/kY3dJOJ.png
cans teleport in at the right, get fed into the network thing from that one mod that distributes them among the canneries that power the generators that power the motors that power the canneries, then the whatsit on the other side grabs the excess filled cans of lava and teleports them back
its self regulating and can quickly produce enough canned lava to give two dozen turtles each 128 cans, and they burn like one can an hour while strip mining

Roblox Studio scripting uses lua, but i did not find a way to utilize it yet
jaunty jetty
so one of the things that really annoyed me at the time is computer craft used teh version of Lua before the version that added a bunch of OOP stuff that would have made many things far easier
so as an example, all of your variables were either temporary, or in the global namespace together
turns out I had an annotated version already prepared https://i.imgur.com/Y9oMLKB.png
