[limpid sedge]

is this one better

its for the different modes, of the bno085 where in i2c u connect to sda etc, but uvc u connect to the rx

wanting both options

[ebon dew]

in that one your gp13-15 are all connected to GND, that's what the red dots show

[limpid sedge]

ooh

ok yea thats a probkem

here is what i need

wiring options for both of these

Board 3V to sensor VIN (red wire)
Board GND to sensor GND (black wire)
Board SCL to sensor SCL (yellow wire)
Board SDA to sensor SDA (blue wire)

Board 3V to BNO085 Vin (Red Wire).
Device GND to BNO085 GND (Black Wire)
Device RX to BNO085 SDA (Blue Wire)
Board 3V to BNO085 P0 (Purple Wire).

ive already done the first one, im trying to have an option for the second one

is it best to have 2 headers to short, one for the sda and one for the 3v

[ebon dew]

i don't understand why you want to short SDA, that's your data line

if you want to reset the chip that's what RST is generally for.

[limpid sedge]

i mean i need both modes avalible

i2c and RVC

[ebon dew]

why not use a SPST switch instead of a jumper?

[limpid sedge]

whats this?

[ebon dew]

a regular switch you flip

[limpid sedge]

ooh, but how would I wire that in the back ends?

cause these are the events that need to happen when switch is flipped

SCL is cancelled
SDA rerouted to RX
P0 is shorted

[ebon dew]

let's take this to the hardware design topic instead of general

https://discord.com/channels/327254708534116352/656770973852237844

[thick wind]

You could also directly solder it down with male header pins for a permanent connection.

[limpid sedge]

i decided to use the pico anyway, but the whole point was to not solder anything permanetnly, i should have been more clear

[late fulcrum]

Ah, one approach is pogo pins and these clamps https://www.adafruit.com/product/2456

[thick wind]

I think in that case, your best bet is pin headers in corresponding female socket headers.

[wanton thistle]

Theres a WT32-SC01 on Ali-express that looks really...interesting. Anyone ever use one of those?

ESP32 + a 3.5" screen 🤔

[frigid tiger]

I wish phones had some kind of pass through mode where you could use them as dumb usb drive

[wanton thistle]

if you havee an android phone you can do that

if you mean as a flash drive

[tiny horizon]

I have one at work, it's pretty ok-ish except for the GPIO is brought out to a weird header size, so my male-male pins get a little crowded. The display update speed isn't great (it's a SPI display), but it's nice to have classic Bluetooth unlike a lot of the other similar devices. There is a WT32-SC01+ (plus) and a MakerFabs board both using the ESP32-S3 and a parallel LCD interface instead of SPI. They have much better performance, but much fewer pins to work with. On the MakerFabs screens, all that's available is the I2C and two GPIO pins. I haven't looked closely at the WT32-SC01+ but I assume the situation is similar owing to most of the pins being taken up by the parallel interface.

[wanton thistle]

Nice to hear from someone who has experience with it. I did look at the SC01+ just to have around

My next project should literally be the largest PIC (40 pin) I can find, with the largest memory I can find, and make my own Dev board display lol

[tiny horizon]

I'm hoping someday for an ESP32-P4 based display board, should be a nice bump up from the S3

The controller was just barely announced though, so prolly be a while before it makes it into products

[kindred kelp]

[late fulcrum]

I was going to use a 40 pin PIC for a pinball project but then I realized I prefer the AVR architecture

[frigid tiger]

You should make the windows XP space cadet pinball machine real

Mine was the "All your Base Are Belong To Us" pinball. You'd rack up bases, then when the ball drained, it'd count them up "Base, base, base, base, base, you have no chance to survive make your time"

[gusty torrent]

I reckon RP2040 PIO could offload all the refresh work for DRAM.

[tardy badger]

PIO could do DMA with SPI so even better

Just pump data into the DMA registers as fast as you can and offload with PIO

Well, grump. I've subscribed to Diyode magazine ever since its first issue, even though a mail subscription from Australia was expensive. But this issue is their last print issue.

[fierce prawn]

Should I add security key auth to my app
I already added code sign on

[cinder wind]

@dusty citrus o/

[limpid sedge]

ok thanks

[frigid tiger]

Does every project feel like you just have to buy more things

[wanton thistle]

for the mos part yea, until you have stock of common parts. But then you need a SMPS or a special op-amp or a bigger micro..etc

[fierce prawn]

Mine doesn't
I run my own online dashboard

[late fulcrum]

When my local Radio Shack closed, I bought all their carded stock so I have my own Radio Shack now. I figured I'd never need to buy parts again. I was wrong.

[fierce prawn]

Even if I need to do two factor auth
I just use my phone
Even on laptop

They use ble to exchange keys via the chrome browser

I don't buy yubikeys

[late fulcrum]

I tried assembling a U2F Zero but then realized I had to run a DOS-only program to initialize it

[fierce prawn]

The chrome browser cross requesting key via ble is good cz I have a inbuilt security key on my phone

[tardy badger]

This doesn’t sound like a very good practice from a cybersecurity standpoint. It can just get a key over BLE? Do you have to unlock your phone or can it request it without you touching your phone?

[fierce prawn]

You need to unlock your phone
Then auth with your lock screen or biometric

And you need to initiate it from the browser too

[tardy badger]

Ah okay, that’s slightly better.

[ebon dew]

When 2FA really ends up becoming more like 3FA or 4FA on your end of the equation.

[tardy badger]

Speaking of parts, it figures the one time I splurge on 2nd Day Air it gets delayed somehow (it’s been at the local hub since Sunday) with no update in sight

[late fulcrum]

It be that way sometimes

[fierce prawn]

I usually cancel the os native security key prompt
Then chrome browser security key prompt pops up and I select my linked phone
Then on my phone there's a notification that says a site wants to verify you
I click the notification then it connect to my laptop via ble and I auth with my fingerprint then just like normal U2F it exchanges the keys and so

[ebon dew]

Do you get your money back if it doesn't arrive in time for the additional shipping charge? Like can you ask for a refund on that?

[tardy badger]

From Digi-Key? I’ve never tried

[ebon dew]

from anywhere

[tardy badger]

I need the parts to make more of IcyBlue to send 1-2 to CrowdSupply

I just need buttons D:

I bought like 500 of them

[fierce prawn]

Opps
It doesn't works with python package repos, pypi.org

[ebon dew]

ah thanks for the reminder i need more tall 6mm's

[fierce prawn]

It just times out

[tardy badger]

Buttons are essential

I bought 500

Lol

[ebon dew]

I need some 10 or 11mm tall for the tr-cowbell due to enclosure height but only place i can find them is in a pack with a ton of other sizes

and the multi color caps for them

because i like the way the multicolor ones look, makes it look more fun.

[tardy badger]

Adafruit sells the 10mm ones

Or I thought they did at one point 🤔

[tardy badger]

https://www.digikey.com/en/products/detail/CT110211.5F100/16607877

Here ya go

[ebon dew]

in the big circle pack yeah

ah sweet. i tried hard to find them and couldn't.

[tardy badger]

Actually these are what you want https://www.digikey.com/en/products/detail/CT110217.0F100/16607629

Much much taller lol

[fierce prawn]

Actually can a rp2040 function as a yubikey

[ebon dew]

i was searching tactile switches then sorting by height and that resolves very little. was going about the search in the wrong order.

11.5 is perfect actually because that's the tallest one i have in the assorted pack i got and they fit almost flush to the top of the enclosure.

i actually designed that part of the enclosure around that specific button height.

whew thank you 🙂

next revision i'll probably go with some khail switches instead.

actually, nvm i don't think i'm going to do anymore of the current revision anyway due to the mcp23017 debacle. might as well redesign the entire thing from the ground up anyway.

[tardy badger]

11.5 is the height from the contacts to the top

Check the data sheet

[ebon dew]

the button caps add just a tiny bit more height, just the right amount 😉

[tardy badger]

Ah

[ebon dew]

some of the first batch didn't have the tall buttons because i hadn't designed the enclosure yet

like the one JP got has those really soft gel top buttons that feel like cats paws.

kind of experimented with different button types

[tardy badger]

Ah okay

It’s snowing

And blowing

And setting up massive drifts in front of my garage door

[dusty citrus]

wow what section of 'the' country is that?

[tardy badger]

Utah

[dusty citrus]

(haven't looked at today's wx yet for the nation (usa) as a whole.
Okay utah that make sense.

I think the Bitterroot forest is near Montana in the south. Friend lived there. wait that's idaho I thing. oops idaho != utah

[tardy badger]

We haven’t had snow on the ground for the last few weeks

Mostly just in the mountains off from where I am

[dusty citrus]

[tardy badger]

[ebon dew]

Cool that someone else actually recognized gatorland in that gif ❤️

If you look close you can see there are like 20-30 gators in it.

[ebon dew]

I think you give all Floridians too much credit. Any one of us could appear in a headline at any time. Thats what makes this place so exciting. 😅

[tardy badger]

I’m from the part of Florida with science

I was born in Florida, spent part of my childhood there too

[ebon dew]

Its still Florida though. Even a female astronaut drove across state lines to murder a woman. Wearing a space suit so she didnt have to stop for the restroom. I think its the air here.

[tardy badger]

Waking up at 3am to see the shuttle launch was a real treat

[tardy badger]

I missed this headline

[ebon dew]

Look it up. Yup, that happened. 🏝️

[tardy badger]

Look at that

She wore a diaper according to the article though

[tidal flare]

Florida is a magical place, but not all that magic is Disney magic.

Gator magic is the most dangerous part

I’d say the thing driving Floridians crazy is the swamp gas

[blissful roost]

But Wy(oming) ?

[split light]

What's the benefit of a dedicated USB sniffer like the miniSniffer2 as opposed to a more general logic analyzer? The DSLogic Plus is only $30 more and can be used for things other than USB sniffing. Obviously the miniSniffer2 has dedicated USB input/output, whereas the logic analyzer would need bare wires to connect to, but still.

[mellow turret]

Is the adafruit website down?

[late fulcrum]

The main advantages to a sniffer/analyzer like that are a) it decodes the transactions to give a higher level view of what's going on, and b) it can record the data from long intricate transactions and log them for various kinds of downstream analysis.

They're both useful tools, there have been times when something was violating the protocol, and the analyzer didn't catch it, because it assumed everyone was obeying the specifications, but a logic analyzer clearly showed what was really going on.

[ancient rivet]

working here. which specific site?

[split light]

I saw a post (can't grab link rn unfortunately) where someone was able to export the DSLogic data as a PCAP file and look at it in Wireshark. Would that not privide the same high-level overview as the sniffer?

[mellow turret]

I was searching gyros in the shop and it started taking forever to load and then just not loading, it loads on my phone tho, so i think something is just wrong with my internet 😭 sorry for the false alarm

[late fulcrum]

I'm speaking in generalities. The decoding capabilities might vary or they might not. The DSLogic may have limits on how much data it can work with, etc.

[split light]

Ah, k

I don't have a lot of experience in a wheel chair. Would a standard doorframe be considered uncomfortably narrow?

I'm designing something to cal Ada specs but I also want it to be comfortable

[umbral phoenix]

I don't know that there is a "standard doorframe"

[static flare]

So, standard wheelchairs are about 75cm across in memory's sake

My new place has 90cm hallways

to especially accommodate my wheelchair

[umbral phoenix]

yeah, I think 36" is ADA (US)

[tardy badger]

I thought ADA was 40”?

I lived in an ADA compliant apartment once and the bathroom door was definitely bigger than 36”

Maybe it was a design choice

[umbral phoenix]

(min 32" in a doorway) https://www.ada.gov/law-and-regs/design-standards/1991-design-standards/

[umbral phoenix]

@limpid sedge MicroPython or CircuitPython?

[late fulcrum]

From the manufacturer's data sheet, it should specify the available torque

[limpid sedge]

micro

[limpid sedge]

cool! thanks

`import machine

servo.freq(50)

def interval_mapping(x, in_min, in_max, out_min, out_max):

[fierce prawn]

Why so many starlink satellite

[limpid sedge]

@fierce prawn cause its starlink 🤣

[late fulcrum]

What it's doing is writing an angle, waiting for a bit, then writing a new angle. So to speed it up, just reduce the sleep_ms() value

[crystal ore]

My guess is that they were recently launched from a single rocket, so they're still in the process of spreading out to their individual final orbits.

[frigid tiger]

Is there a guideline for the amplitudes you should use for the formants used to construct a phoneme?

[tardy badger]

If you thought Sam Zeloof was neat and wanted to work with him, he launched a company https://atomicsemi.com/careers/

And he’s hiring out of San Francisco

[fierce prawn]

That means more coverage ?

[frigid tiger]

less downtime I guess

[late fulcrum]

Heh, I saw "Sam Zeloof" and thought "Paul Zaloom", who would be fun to work for

[steady dove]

👋 @late fulcrum

[crystal ore]

Yes, they want to cover the Earth 24/7, so they want to be spread out.

[fierce prawn]

Wait so satellite drives themselves
I thought they just float around

[late fulcrum]

Mostly they're orbiting, but yes, they do have maneuvering thrusters

[fierce prawn]

Won't the fuel ends

[tardy badger]

Most starlink satellites have a lifespan of maybe a year or two

[late fulcrum]

Yeah, the fuel doesn't last forever, but once they're in position, it doesn't take much to keep them there.

[tardy badger]

Eventually they’ll run out of fuel and burn up in the atmosphere

[crystal ore]

Just to be clear, they orbit around the Earth very fast, not float in place. The thrusters just let them slowly change orbits.

[fierce prawn]

So that's why I the video I see a bunch of them moving fast

[crystal ore]

Yup, around the whole Earth in about 90 minutes.

[fierce prawn]

Actually can I own one satellite without shooting them out

It would be fun for experiment

[lusty fossil]

Cube sat?

[frigid tiger]

Ya cube sat

WE ARE LIVE! ASK AN ENGINEER! https://youtu.be/f-aekzi6kFo

[crystal ore]

Yes, cubesats are often batched up in launches so you can share a rocket, etc. They're still expensive, though, even a small one is probably $50k to build and launch, plus a lot of paperwork and operational stuff.

bicycle bottle dynamos usually attach one terminal to the frame and the other to the wire that goes to the bulb.

I hope Adafruit appreciates the number of small things I buy from them... LOSE, buy new ones, and then find the original. I'm darn near buying every project twice at this point.

Currently missing an eye spy cable I just bought, and some feather stacking headers that I bought sometime ago and no evidence I used them.

[tardy badger]

Let’s hope UPS doesn’t lose my Adafruit order too.

[ruby pendant]

Oh I don't mean UPS, I mean my desk.

Well and possibly on the eye spy cable it might have been my ferret, seems like something he'd steal

[whole jacinth]

that's… not how AC works, at least probably not at the frequencies that dynamo is working at. it's more likely that current is flowing in both the wire and the frame at the same time, but the direction is reversing on each cycle. for what you propose to work, the AC frequency would have to be so high that the wavelength is on the order of the distance between the two terminals that you attach to the frame

[tardy badger]

I know, I’m just frustrated by UPS

[ebon dew]

I'm still waiting on my Pi from Pimoroni, been about 3 weeks and they didn't provide any tracking.

[tardy badger]

Royal Mail?

Royal Mail international shipping was having issues due to a ransomware attack

[ebon dew]

ordered on Jan 20th but see now it didn't ship until Feb 6.

so not quite 3 weeks but feels like a month since that's when i ordered it. they recommend only reaching out after 3 weeks have passed.

It just says international standard, nothing about royal mail.

[tardy badger]

International standard is very likely Royal mail

[ebon dew]

no octoprint yet 😦

but i did get some new 2040 aluminum extrusions to try to extend the print bed.

need a custom cut bed and carriage plate. thinking about using sendcutsend or whatever that new metal service is called.

as long as i give them accurate 3D files that should work.

[static flare]

That reminds me, I need to finish disassembling my old 3D printer to harvest for parts

(for a new one)

[ebon dew]

[static flare]

I bought an old all in one model a while back and I want to be able to easily mod it and such so I'm deciding to break it down and remake it from scratch, just need some sort of guide to follow

[ebon dew]

i have an old anet a8 i never got to use, not a single time. everything rusted including the lead screws. whatever isn't acrylic is just rust.

[static flare]

ohno

[ebon dew]

working with extrusion is a lot like working with lego technics. it's all just bolt together stuff very easy. the older style arcylic ones from like 8 years ago were just too hard to modify. aluminum extrusion for the base, axis, and gantry really is the way to go.

[violet parcel]

why does the wave of AC kinda looks like PWM?

[static flare]

That's what I'm looking for, ultimately

[violet parcel]

except cut in half horizontally

[ebon dew]

you mean a sine wave?

[violet parcel]

yeah

[ebon dew]

2 phase is opposite sine waves, 3 phase is 3 waves.

[whole jacinth]

what do you mean by cut in half? are you looking at rectified AC?

[ebon dew]

PWM can modulate the peak to peak pulses, hence pulse width. AC expects a specific wave frequency.

a lot of things in electricity look similar, it's all electric.

square waves are just digital sine waves

[whole jacinth]

if you PWM a sine wave, it'll look like a regular sine wave after filtering, but with a DC offset (unless you're doing something that can do bipolar output, or level shifting)

[violet parcel]

i mean like pwm doesn't go under the x axis like a sine wave so no negative voltage* (normally unless you plug the motor wrong)

[whole jacinth]

yeah a PWM peripheral on most MCUs won't produce negative voltages

[tardy badger]

Get an opamp, charge pump inverter to generate your negative voltage to supply to your inverting input and bam bobs your uncle

It’s more complicated but I like to oversimplify unfortunately

[whole jacinth]

this is why motor divers have H-bridges: drive both ends of the winding to get the required AC, as long as you don't need to ground one end of the winding

[violet parcel]

but motor can generate back emf with volateg and amp right? so on an oscilloscope the back pwm signal would looks like ac?

[ebon dew]

@static flare if you intend on using extrusion with rollers make sure to get V-slot extrusion and not T-slot extrusion. roller wheels for modern printers all use v-roller wheels.

[whole jacinth]

what kind of motor? brushed DC? brushless? induction?

[violet parcel]

brushed or brushless(when i can afford it)

[static flare]

Okay! I'm considering something similar to a Hypercube design, but I'll need to do more research and find some schematics and instructions and such

[whole jacinth]

with brushed DC, the AC voltage of the back EMF will get commutated, so it will effectively look rectified because the commutator is switching the polarity every rotation (simplifying a lot)

[violet parcel]

ok do dc motor absolutely need pwm or they break or one can connect one to a gpio and a resistor in series before it?

when i was a kid i broke several dc cheap motors because i didnt know about amps but it is nice to just test if my motor works without having to code to send a pwm signal to it or will that break it too?

[whole jacinth]

most GPIOs don't have anywhere nearly enough current drive capability to drive a DC motor

[whole jacinth]

depending on your specific DC motor, hooking it up to a DC power supply might work, or it might overspeed it, depending on the specs. a lot of "hobby" DC motors are specified to run at a specific voltage, and they might be designed to not overspeed as long as you stay below that voltage

[violet parcel]

like back then i didn't know anything and would just plug it directly to a 9v battery and it would blow up in a couple of seconds

i assume it was because of a lack of resistor?

[whole jacinth]

yeah lacking a resistor is one possible cause, and/or too much voltage

[violet parcel]

and just because it was a very cheap 10 centa motor in a 5 dollar r/c?

[whole jacinth]

it's hard to say without seeing the motor

[violet parcel]

oh it's probably still the same ones in toysrus or walmart 20$ r/c now a day. I just want to make sure to not repeat the mistakes

but Ive seen similar ones on digi-key etc in the 1$ range, as simple as can be, 2 fragile looking solder and a red and black wire

these sort of motor always came with the chepeast possible alkaline battery usually an eveready back then that was marked as "heavy duty" but would be out of juice after the 10 minutes evaluation period

[whole jacinth]

3 or 4 alkaline cells, especially if they're small like AAA or AA, might also have enough internal resistance to limit the current to safe levels for those motors (old Lego Technic motors used 3xC cells with no current limiting, i think)

also, running a motor with no mechanical load is a good way to overspeed it if you're not doing current limiting. if it came attached to a gear box, leave that on while testing to provide at least some mechanical load

[violet parcel]

that part is always a bit confusing to me, let me find a specific example. Like having the same battery power both the motor and the arduino so it can send pwm to it to drive it but the motors usually need a different voltage. So I have to use a shield because I have no idea how to do it myself

specially sending 2 ground from 2 different circuit is what confuse me

[violet parcel]

here would be an example

Im confused because the arduino and motor are 2 different voltages yet Id have 2 ground to the same powerback with 2 dfferent voltages. Red is power, black is GND and blue is PWM

or Im supposed to use 2 powerpacks ?

btw I just randomly took the first I could find on google that seemed to be electronics sized, not an actual potential purchase as an example

[manic rain]

if I attach a rectangular magnet pole-wise to the spoke of front wheel, will it induce DC inside fork blade? How can I direct it to the LED?

[violet parcel]

seem my bad drawing killed the convo 🤣

when I told you Im very bad at drawing and I never improved despite taking courses and spending around 6000 hours on it I wasn't joking

[late fulcrum]

Many Arduinos can run on 9V (they have an on-board regulator)

[violet parcel]

yes but does the voltage of the GND matter ?

the motor was says 24V would it be an issue the GND is 5V from the arduino and 24V from the motor ? Could it trickle back in the GND wire of the arduino and destroy it (ie: like negative voltage/AC)?

[late fulcrum]

Generally it's used as a shared reference, so everything agrees, but in cases where there is significant current flow, you may have to pay attention to voltage drops. Also, on your picture it was 9V, not 24V.

[violet parcel]

voltage drop? like leds or as in the difference of voltage between the two GND ?

[dusty citrus]

If you check with an oscilloscope's probe tip (leaving the scope input floating with respect to ground) and probe the points you think are ground, you can get a comparison. If they are not close they are not referenced to the 'same' ground.

Risk of smoke when you even try. ;)

That applies to mains powered oscilloscopes using 3 prong interconnect to commercial power. idk what happens with battery-operated oscilloscopes (at all).
The recommendation to test grounds that way came out of Tektronix literature. A scope primer.

https://www.qsl.net/w2aew/XYZs_of_Using_a_Scope.pdf said primer ;)
p.22 lower right has the cited advice.

[timid wave]

Hey guys, so i have recorded the power across a load overtime delievered by 3.7V li ion battery, and by recording the power value each second, i have plotted a graph of power vs time. How can i calculate mAh of battery ? (I also have voltage and current for each second logged)
x axis is time in seconds
y axis is power in milliwatts
the jump at 2080 seconds is because I decreased the value of load resistor
End time = 6277 seconds
Summation of all power values = 12699253.07 mW
Is it even possible ?
(to calculate mAh of battery)

These are all the values logged
voltage is voltage across load , current is current through load, power is power across load , time is in seconds

[late fulcrum]

I suspect your summation is using the wrong factor somewhere, as I doubt you were able to pull 12 kilowatts out of that battery. Also you'd expect the answer in watt-hours, not milliwatts.

[timid wave]

that figure is just summation of power reading over time , not total power
I WANT to calculate the watt hour and i am asking how do i do that from the values i have

[late fulcrum]

What units are your time?

[timid wave]

Seconds

btw, nvm. i got it 👍

[violet parcel]

kw.h are so weird to me that I don't even want to understand the maths. I just use a converter. considering that 1W is 1 joule per second I don't see why they had to overcomplicate it. Like when they says the US uses X GW.h in a year or my electricity bill says my lights used 6 kw.h in a month I get so confused...

if they used like 6 kw.month Id understand that I have to divide it by (365.25/12)2460) to figure out the watt actually used as in j per second

also it seem that every power company has a different definition. seems like the goal is really electricty bills obfuscation

so that you cant tell if there is a correlation between replacing an old stove with a new one that uses less power and see a lower bill

[whole jacinth]

it's the units that the electric company finds most convenient to use for billing.

along with heating degree days and cooling degree days for seasonal comparisons

[violet parcel]

the only thing i know for sure is that the led bulb above me is rated for around 22w but pulls 23 or 24w from the socket so it uses 0.024kw*h

because no bulb is 100% efficient in real life

just like my 80% rated psu is rated at 650w so it pulls like 800w from the socket

but i dont know how to actually measure it myself so the power company could be making my bill up and I have no way to test

[whole jacinth]

the LED bulb actually probably pulls 22W at the rated voltage. if your line voltage is a little higher, it'll draw slightly more power

[violet parcel]

arent led light bulbs about 95 to 97% efficient?

while incandescent are 98-99%?

[whole jacinth]

incandescent might be 98-99% efficient at turning electricity into heat, not light

[tardy badger]

Scrolled back to find this message to share this cool post from mastodon https://mastodon.social/@tammojan/109915115052032325

Someone captured starlink falling out of orbit

[violet parcel]

so led light bulbs are just bigger arduino style led lights/neopixels ?

[tardy badger]

Kind of

[violet parcel]

did musk really didn't know about solar storms?!

remind me of engineers who disregarded general relativity warnings from scientists and ended up with a cumulative error of 70cm per day in the 1970s...

[tardy badger]

It’s mostly that it’s unavoidable

[violet parcel]

with enough armor it can be avoided no?

I mean how did gps that are up there since 1970s survive it ?

[tardy badger]

Not in LEO, and not given the fact that they’re designed to burn up after a certain amount of time anyway

[violet parcel]

Im sure a satlink in a satellite armored like an m1a2 sep would survive it..

I see

[tardy badger]

LEO satellites rarely ever has shielding to protect from solar storms because the missions are considered short term

[violet parcel]

wait starlink is the name of two types of satellite

[crystal ore]

It's not that the solar storm fries the satellite, it's that it heats up the atmosphere, which puffs up and causes more drag during the critical period where the satellites are trying to raise their orbits to where they should be.

[violet parcel]

was that a musk satellite or an old communication satellite with the old starlink for cars?

that fell down ?

Btw for the motors earlier I asked because someone asked about 6 servos the other day in #arduino they were powering a helmet with directly from the arduino

and I knew it was an issue of not enough power but I couldn't explain to them if they needed another battery ppack to connect the batteries to the servo directly and only use the arduino to pwm them

was the super standard sg90s

Sorry I didn`t realize that I know so little of how space works near our planet. I thought the sats were already in orbit and heat is kinda bizare for me when afaik it's around 13Kto 100Kelvins around the planet in space and if I spitted there it would freeze instantly

[tardy badger]

A lot of space like where the ISS orbits is not terribly hot, in the sun averaging like 50-60F. It’s weird.

[violet parcel]

isn`t it because there is no items around to accumulate/keep the heat ?

since it`s a (near)vaccum ?

[tardy badger]

But also even if it’s cold, thermal transfer is so slow it would take years to freeze

https://sitn.hms.harvard.edu/flash/2013/space-human-body/

[violet parcel]

where as in the artic there are a lot of matter to keep the heat and the atmosphere also retain it

[tardy badger]

Right

Anyway, space is weird

But so so cool

[violet parcel]

Wouldn't I lose my heat though throught radiation and that would be the cause of my (quick) death and not the cold?

Obviously Im neglecting other effects like the vacuum taking fluids of me and hard radiation by being unprotected in orbit in space

Also I'd rather it doesn't happen because I don't like seeing that I'm rotating at 14000 mph

[tardy badger]

You would died of oxygen deprivation before you’d freeze to death

[violet parcel]

yeah I was neglecting that part just focusing on the temperature thing 😄

[tardy badger]

Plus possibly other blood/air pressure related issues

[violet parcel]

Also like I mentionned Im able to ignore that Im rotating at 14000 mph on Earth BUT

I'd rather not see it

And continue to pretend to ignore it

[tardy badger]

Hypoxia would set in within 15 seconds, you might have a minute of lucidness before drifting into eternal sleep

[violet parcel]

It's like vertigo for me if I don't see that I'm 100 feet above the ground I'm no scared

But if I do panic sets in

[tardy badger]

There’s estimated to be about a minute and a half window to save someone from the vacuum

And permanent brain damage

[violet parcel]

Ive seen astronauts comment on this before saying it's not that quick if the glass break

but I have no arguments to otherwise present

It's still an emergency that would use the jets on their suit for

[tardy badger]

Yeah

[violet parcel]

but it's not a 1 minute thing apparently

They were commenting on the movie where that happens in the opening scene

I think chris hadfield was thinking about it ? or the first woman astronaut in the US ? on youtube nasa channel or wired or something similar to this

[grizzled raptor]

They say the closest theatrical representation if space decompression and all that was the scene from 2001: a space odyssey, when Dave has to leave the pod to get back on the ship, and he didn't have his helmet.

That could what they were talking about

[violet parcel]

What surprised me a bit is that they weren't so concerned if someone tether broke off but I don't know why

was aslong the line of probably could be reached by the robotic arm or could probably drift back to the ISS with a speed difference like if they throw something behind them

But apparently using the jets is a very very last resort

I think the movie was gravity (2013) ?

And there is a fight/explosion into the ISS

[grizzled raptor]

Yup, that is also a pretty good representation of it the experts have said.

Sandra bullock. Good film.

Most get it very wrong. Like the instant head popping we've seen in some films. Like the OG total recall.

[tardy badger]

That film gave me tons of anxiety

Gravity

[violet parcel]

Well they gave it 1/10 for realism

[tardy badger]

Interstellar was cool though. Tons of science research went into it

[violet parcel]

especially the jets thing, dying instantly in space, that there would even be a fight, misrepresentation of how gravity works

[grizzled raptor]

Ahhh, okay then mulhorand, I stand corrected.

[violet parcel]

1/10 for gravity I mean 😄

not interstellar

[grizzled raptor]

Have you seen 2001?

Old school one of course.

[whole jacinth]

wait did they remake 2001?

[tardy badger]

I think the people died from impact with the debris

That was my interpretation anyway

[grizzled raptor]

No no remake of that one.

Old school movie of course, 1968. Because it came out 55 years ago.

https://youtu.be/t2jibvQfTK0

about 4:10 in it actually happens

[violet parcel]

I kinda enjoyed contact but always thought it was pseudo-sciency and also really disliked 2001 space odyssey because I didn't understand the story that was being told and asked for a refund after 30 minutes but I wasn't on anything

And I was told to fully enjoy the movie "one had to be on mush or a joint" or something

but I was never interested in such things so

[grizzled raptor]

The book explains much more.

The monolith was left by aliens. It trained the monkeys, killed ones that failed the mental tests. They created humans. The monoloth on the moon was the test to see if we advance enough. The deep space one was to see who was the chosen one. The star child.

That's it in a nutshell. We are a science experiment.

They created humans through intelligent selection .

[violet parcel]

I don't know if it counts as a remake but I saw the one where there is a monolith on mars

and it teleports to the artic etc

[grizzled raptor]

The second movie. There were a coulme books.

[violet parcel]

(and I don't want to see more and spoil the ending since it's under the 5yr old movie exemption for spoilers)

I think the movie came out in 2020 or so

[grizzled raptor]

Oh, I see.

Didn't even know that.

[tardy badger]

You know what space movie terrified me as a kid but I find hilarious now?

Mars Attack

[violet parcel]

It felt like a remake of space odyssey except with a mix of total recall

Yeah when we went on mars that really shattered my illusions and sprituality

Since then I don't feel that mankind is any special and I don't feel like it's worth spending much money on space anymore

Since our solar system feels empty and boring and not special at all 😦

[tardy badger]

I mean, it’s pretty wild that we even exist

[violet parcel]

Yeah but I find it hard to believe in afterlife even though it's special that we exists. But so do cats, or intelligent things like whales and dolphins

[tardy badger]

A 10% chance every 100 million years in favorable conditions

[violet parcel]

For the afterlife it's because no one ever came back so who's to say my theory is any more valid than anyone else?

[tardy badger]

Regardless, life can be made special by enjoying the rarity of our existence

[grizzled raptor]

the fact the perfect combination of elements combined just perfectly to create a single cell organism is spectacular.

and the diversity of fauna and flora that spawned from just a single cell is another spectacular thing.

My wife is a biochemist, so i learned alot while she was learning.

[tardy badger]

Life apparently has the odds of 1:10^2685000 chance of forming

DNA forming has slightly better odds of 1:10^90000

[grizzled raptor]

thats a lot of zeros

[tardy badger]

But considering they estimate 2^80 atoms in the universe, it’s very overwhelming odds

1,208,925,820,000,000,000,000,000 atoms

Roughly

Whoops 10^80

Do I have any way to move water from a source that's likely at a ground level, to a tank that might be at the same ground level or a little higher, without using a pump, and preventing backflows from tank to the source?

Maybe with a check valve, but I don't think that it will work just fine

[crystal ore]

The "or a little higher" part is the problem. To raise water against gravity you need some sort of an energy or power source. So it just depends on what constraints you're operating under. Like, you said no pump, but could you use a windmill? 😉

[limpid sedge]

anyone know how long adafruit will take to ship something to the tri state area?

just a rough estimate is all i need

[fair summit]

the shipping window for a day closes at 11am Eastern. The shipping times are what the carrier would predict from New York, NY to your location

you can pay more for faster shipping

i live one day away by UPS ground,. If I order after 11am, it goes out the next day, and arrives the day after that. Very occasionally there are 1-day hiccups.

[limpid sedge]

alright thanks! also minimum order chagnge in effect end or start of march?

[fair summit]

that's for purchase orders, not for prepaid orders

there is no minimum for prepaid orders

[dusty citrus]

If it's at the same height?
I guess that there aren't like diodes for water systems or aren't there?

[fair summit]

backflow preventer: https://plumbingtoday.biz/blog/what-is-a-backflow-preventer-and-how-does-it-work

[whole jacinth]

if the destination is at a lower height, a siphon (maybe with a check valve) might work

[whole jacinth]

is your source pressurized (like a faucet)? or is it another tank or something?

[dusty citrus]

That's called a ram pump. Montgolfier Brothers (the hot air balloon) invented it.

https://en.wikipedia.org/wiki/Montgolfier_brothers#Other_Montgolfier_inventions

[dusty citrus]

The source is pressured
There's some space between the source and the ground, so it could be used to add stuff to collect the source

Forget sbout my previous pick it was no sense 😅

There's not much space between the source and the ground
I need a way to transfer that water out of that space and storing it somewhere

[limpid sedge]

are long headers like this breakable

as in can i make them into 3x1 parts

[urban arrow]

If I'm reading my recent order # correct, it's 3024036, which means that since they celebrated 3 million (seems like just days ago), we've ordered over 24,000 since. Man great! Don't know how they keep up! I love LadyAda and family (hopelessly addicted).

[late fulcrum]

Yes, they cut fairly neatly and easily between pins

[limpid sedge]

ok

from the BNO085, how would I calculate "G" Force amount

You'd divide the acceleration (in m/s^2) by 9.8 to get gees.

I'm getting good at having ChatGPT help me write code. I'm making a robot that follows a laser, so far I'm just on the laser tracking part. It takes some back and forth, ask for something basic then keep asking for more things. I have probably written 12 out of 120 lines and it works great. You can't ask ChatGPT for much at a time but if you keep building it up then it can be a powerful assistant.

Anyone have recs on how to deal with this wall box? It's a metal box, poorly installed, feels like it might be attached to a stud on the left and nothing on the right,it just bends away when pushed. I'm guessing it would be easier to just replace with an old work PVC box rather than try to fix, so that's what I'm attempting to do. But I'm not sure how to get it out. Assuming it's attached to a stud on the left, like I dunno, how do I get at the nail?

[steady dove]

Those are the only two Nintendo hand helds I like.

I did modify an EU Playstation with a US power supply so I can play PAL games (via a PAL-NTSC converter)

[timid anvil]

So you can play both?

[late fulcrum]

Probably I'd try chipping away at the plaster to get at the joint between the box and stud and then attack it with a wonderbar or equivalent prying device.

[wooden schooner]

that's what i've been doing and boy... i think the metal box's front plate was installed backwards, so that the flanges faced the wrong way. At this point there is only one corner still attached and it appears to be screwed in from the top (??)

unfortunately this is drywall that definitely contains asbestos

Aha, here's the fastener... can't tell if it's a screw or a nail

Are you applying for secretarial positions? I don't think they'd matter for engineering jobs...

[hushed cave]

just figured microsoft product experience is in every posting and a cert might create some interest

maybe I'll spend more time on some fun projects

[tardy badger]

Definitely focus on projects, document them. Share details and progress on LinkedIn, GitHub, your resume, etc..

I actually got found for the startup I worked for because of the projects I worked on and shared on LinkedIn

[hushed cave]

I would actually have something to post on linknedin too

[tardy badger]

And also I am able to lean into projects during interviews to help bridge knowledge gaps that my job doesn’t exactly provide

I have more followers on Linkedon than I do any other social media platform lol

Over 2000

[hushed cave]

I guess I should start with a job I want and pick a project around that.

[tardy badger]

I’d focus on projects that help you demonstrate skills more broadly

But also that are interesting

If they want coding experience, build something in the language you’re expected to use

[hushed cave]

this sounds like it carries more weight than "hey I took this test and passed" lol

[tardy badger]

Like implementing a light controller with FreeRTOS on a Arm based WiFi or Bluetooth microcontroller

This is true. A completed project is worth much more than tests. The employer wants to know whether you can actually solve their problems and build things, not guess a multiple-choice answer.

[tardy badger]

Exactly

Plus projects give you the opportunity to share difficulties and how you overcame them which highlights the problem solving skills EdKeyes mentioned

[hushed cave]

they could also sub for the certs as experience

well there goes 200 dollars in test fees but maybe they'll be useful for something later

[tardy badger]

Certificates are kind of useless if you can’t apply it

Which is why demonstrable projects will always carry more weight for hiring managers

There will be a few places that care more about credentials than they do ability to apply knowledge but that’s changing pretty quickly

I’d only consider certificates as supplemental to actual experience doing things either on personal projects or in your current role.

And this is also feedback I’ve got from recruiters too

[hushed cave]

and thanks for sharing it

I've been kind of aimlessly trying to find something to make me a better candidate so I appreciate the help'

[tardy badger]

Definitely! Think about the role you want broadly and then google “x career project ideas”

That’ll give you something to start off on and make your own

So like “embedded project examples/ideas” if you want to do embedded engineering.

[grizzled raptor]

Can Confirm. ChatGPT is a dad. Thats a pretty good dad joke.

[delicate stream]

You definitely want to be familiar with the Office suite, but the certifications are a waste of time and money unless you're specifically applying for a secretarial position, as that tends to be their bread and butter. A lot of organizations are even moving away from Office anyway, using things like Google Docs [some places are totally no Microsoft and use Docs, Workspaces, don't even have Windows machines...]

[tardy badger]

Apple uses its own office suite too a lot of the time

[delicate stream]

Oh yeah, I forgot Apple has an office suite, lol

But most office suites are similar, be they Office, OpenOffice, LibreOffice, whatever Apple's is -- generally they do a word processor, spreadsheets, slideshow, and have similar options and layouts and whatnot

[hushed cave]

Thoughts on cad certs? AutoCAD was my next exam to take.

[tardy badger]

What kind of engineering degree did you have again?

Mechanical?

[hushed cave]

Yup!

[delicate stream]

I'd say in general, only get certs if you're looking at a job that wants those certs... otherwise you may never need the certs. For example, I'm in IT, and while the A+ is a standard, I've yet to work in a position that required it

[also some certs, like the A+, lag pretty well behind industry standards, so they're not really helpful anyway]

I almost got my A+ in like 2002, but they still covered Windows 98 as the newest if I recall... when 2000 and NT were pretty common

[tardy badger]

A+ is actually a lot better now

[delicate stream]

O ya? Well, still, it's time and money to get it [maybe just time and effort if your company will pay for it], but it's not generally necessary

Especially since now A+ needs to be renewed, if you get that and don't use it, you really did waste the money

[assuming you actually know the contents of the A+ anyway, when I was thinking about getting mine, I knew some stuff better than the training materials, lol]

[tardy badger]

Lol

A+ and Network+ are very desirable these days for IT admin roles

But I digress

[delicate stream]

Oh yeah, there's definitely a want for them. But it depends on the job. I'm just the IT admin for a single school of a few hundred people, and it's a hodgepodge mess; A+ certs don't help you when your servers are 10-20 years old and held together with duct tape and a prayer

[tardy badger]

Don’t forget the sketchy software patches they paid that one smart kid to write 7 years ago

[delicate stream]

Mhmm

Fun fact: ChatGPT-3 can forget things

And I got it stuck in a rut, lol. Had it make a "Universal Paperclips" Python game, and have hit an error that it always spits out the same "corrected" code for. Even when I tell it that there aren't any changes or it's the same thing as what it just said, lol

Ah, wait, fed it back the code it keeps spitting out and said "doesn't work" on the end, and it made a change, lol

they didn't know what to say : 🤣

[tardy badger]

Lol

[violet parcel]

not that it makes sense because humans are kinda always radioactive especially those who eat lot of fruits & vegetables

but I thought that was funny at the time

also when you take an xray and they says it's not dangerous but they have a 60 pounds lead apron while being near you and they are in a nuclear vault when they take the xray

Where in Europe can someone purchase Adafruit Lipo batteries?
Pimoroni has similar ones, but I was wondering if the actual adafruit ones are available there.

You can check for distributors here https://www.adafruit.com/distributors

[barren yoke]

Did that - dug thru a handful of the bigger name websites and no lipos to be found. (clarification -- none of the adafruit lipos)

[delicate stream]

sure

[late fulcrum]

Hmm. Maybe try the DigiKey site for your part of the world and look for Battery Products -> Batteries Rechargeable (Secondary) then filter manufacturer by AdaFruit. However, it may be that due to the difficulties of shipping lithium cells, that AdaFruit ones are just difficult to obtain there.

Manic Panic on Amazon, lol

[tardy badger]

lol

[hidden kayak]

hello, i have some cheap electric air duster that died (was a gift exchange amazon/wish thing)
looks like it died somehow.. after a couple weeks of use (not surprised lol)

its using a usb c plug to charge, the led doesnt light up. im wondering whats wrong with it, so i took it apart.

i tested the battery pack with a multimeter, i get 11.85v .. (3 batteries in the pack, im guessing 18650) so looks good?

the dimension of the microcontroller? board? is 30mm by 34mm.

the switch is normally opened.. but the third leg for NC config is still present.. i did feel some warmth when the battery was full, and im wondering if this was causing some overheating/drainage..

the third leg is not soldered in the board like the 2 other legs

sorry this is a big wall of text. i can provide pictures if needed?

is there a microcontroller i can use to replace it? or an easy way to fix this?

or can someone redirect me to the appropriate channel?

[ebon dew]

picture of the area of the pcb could help

yes pictures, as many as you can of both sides of the pcb as close as you can, clear images please.

[ebon dew]

the third leg is optional that's fine

if you look close it'll say NC, NO, C

[hidden kayak]

yup

[ebon dew]

Normally closed, normally open, common

it's a configurable switch, with options.

depending on how it's used

that's not the issue and i don't see anything obvious jumping out. maybe some kind of mosfet overheating. look for signs of tiny burn spots on the mosfet.

You can use a multimeter with continuty to test some traces

what does the little black wire go to the battery pack?

[hidden kayak]

mosfet is the dp3080, c1l0208 square one in the back right?

[ebon dew]

because on the back one of the silkscreens say NTC which is a thermistor

[hidden kayak]

yeah the thermal probe was touching the battery pack, makes sense

[ebon dew]

yes the dp in the back

LDO near R16 should be looked at closely, power regulator

actually looks like there's two of them the other near R14 too

the 3rd leg of that switch is probably not connected to anything, can't be 100% sure without a schematic because that traces is running pretty close to it as well.

the switch leg should work, the question is if the PCB actually uses it in any way.

also ii don't see an LED

[hidden kayak]

hmm im no pro, but even with my macro lens on the phone, there isnt anything obvious that looks bad.. like lets say a capacitor that blew

the LED is to the right of r12 i think, just below the connector. thats where the hole in the plastic casing is for the charging LED

i get a beep between C and NC

[ebon dew]

when the switch is still open?

[hidden kayak]

yeah

[ebon dew]

i'll assume the LED is to let you know of charging status so that should still be working even if the on/off switch isn't.

can it only be charged while off would be a good question

[hidden kayak]

hmm, let me try 3 or 4 usb cables

[ebon dew]

do you get a beep between c and nc while the switch is pressed?

[grizzled raptor]

The NC leg isn't even soldered into the board, so it's unlikely it's part of the circuit at all. Not sure if you noticed that.

[ebon dew]

do you get a beep between c and no while the switch is pressed too

yes i'm aware but if the switch is malfunctioning it doesn't matter if it's hooked up or not because i don't see any separation from the NC via meaning it could be shorted to gnd

[hidden kayak]

C and NO, pressed switch, yes

[ebon dew]

now c and nc while pressed

[hidden kayak]

also, tried 5 different usb cables, i get no LED to light up. but idk if i need the battery to be plugged in

[ebon dew]

checking for a switch failure

[hidden kayak]

C and NC, while pressed no

[ebon dew]

led is sitting next to the battery JST so stands to reason it's for battery power? i don't know. i've never seen that board before so no clue how it's supposed to work and without a schematic it's all guessing from this end.

ok that's a good thing switch looks ok

the more info you can provide about what happens when it operates normally is most beneficial for helping you to troubleshoot.

[hidden kayak]

i tried the usb cables, with battery plugged, nothing

[ebon dew]

there doesn't appear to be anything obviously physically wrong visually

[hidden kayak]

so pressing the switch for 3 seconds, turns on the blower, then you can press the button, to have more power, 3 power settings total. then hold for 3 more seconds to turn off

[ebon dew]

possible i'm missing something, having more sets of eyes to look it over is helpful. maybe others here will take a look and spot something.

the logic has to be coming from the b2oc chip on the back

[hidden kayak]

the FMD chip right? fremont micro devices

is there a way to connect to it and check the code?

im guessing usb would be too easy for these things.. probably some weird connection that has to do with 3 or 4 pins on the chip itself

[ebon dew]

i see no information on the b2qchfh or the other small one below it l2f2301

depends on the IC's usually it's hardcoded and you'd need a debugger or logic analyzer.

this is as much as I can help, hopefully someone else comes along and takes a stab at it, i'm out of ideas.

[hidden kayak]

are you aware of any microcontroller that could do the same kind of job as this one? id like to Frankenstein that thing. i like tinkering and this is a simple enough project lol

found some ali express reviews with pictures of the board.. its in russian tho

[wanton thistle]

so I had an MRI done and I really have to wonder what kind of electronics went into that thing because it seems like black magic almost

MRI's seem like magic anyway. "Oh hey we can take pics of your brain if we just align these protons for a nano second"

[tardy badger]

The basics is: they send strong magnetic fields through your body and measure the changes in the field and use that to construct an image

That’s the very un-nuanced version of what happens

[wanton thistle]

yea but I mean, Im trying to think of the circuitry and electrical design to power such magnets

It seems very very complex

[tardy badger]

It is

[wanton thistle]

and I doubt I can find even an inkling of whats involved out of curiosity lol

[tardy badger]

It’s probably one of the most complex medical machines used today

[wanton thistle]

Yes. Probably slightly less complex than LHC

but very very cool tech

I asked the tech and she said "It uses very advanced physics" lmaoo

Shes not wrong

[tardy badger]

John’s Hopkins University says that it realigns the atoms in your body and reads the radio waves emitted

Kind of wild

[whole jacinth]

it knocks on all the protons in your body (with superconducting magnets and RF) and listens to the sound

[violet parcel]

the book about medical instruments design and applications has a chapter on medical imaging including MRI, basically based on this and North-North aligned magnets returning energy to the system whatever that mean

[wanton thistle]

thats even crazier lol

The sounds you hear are nuts too

[dusty citrus]

Those machines are usually docless and crazy expensive to repair
So you find often health facilities desperately looking for repairs men

[wanton thistle]

🤔 this feels like its from Full Metal Alchemist where they list off the percentages of elements in a body ( I know its not)

[violet parcel]

After that it measures the property of hydrogen for the base images

But I assume to make magnets go N-N which they dont do naturally it takes a lot of energy

[wanton thistle]

Yea, I tried looking around the room for any big cords and didnt see any. Id imagine the thing just takes crazy amounts of energy

[violet parcel]

apparently it takes a lot of magnetic measurements, measuring time between signals from an initial excited state of matter etc it filter it out to lessen the noise value that's why MRI takes a couple of minutes according to the book

[whole jacinth]

my understanding is that the superconducting magnet takes a large amount of energy to charge up, but it happily stays that way as long as you keep it (very) cold

[violet parcel]

The book is from 2010, but still the basic concept should still be the same

To image a cross-image of a tissue they varies the exciting frequency of a gradient field

That math is way about my level, just trying to summarize it

it mention superconducting coils and about 2T of magnetic fields

There is two types of MRI apparently, one that uses a magnetic field under 1T but doesn't need superconducting coils but has less resolution but is lower power and still fine for a lot of imaging needs

Hopefully that help a bit @wanton thistle 🙂 I don't understand most of it

It's just 5 pages so doesn't have instructions on how to make one with arduino 🤣

[wanton thistle]

yea, I heard the Cryopump, so it must be the bigger one

at one point the whole thing was shaking and I felt like I was on a rocket ship lol

"It would be cool if this thing could open a black hole, kind of like Half Life"

[violet parcel]

Honestly Id just try to find a patent for one, probably would be easier to understand

Because the claims in a patent have to be understood by the patent examiner to have legal weight.

[wanton thistle]

😅 thats a 10PM rabbit hole to go down. I already looked up what the various sounds were and what they were imaging

[violet parcel]

My hospital almost exclusively uses siemens stuff

[wanton thistle]

I didnt catch which ones they use. Ive used Siemens PLCs though, and they are "OK"

[violet parcel]

this would be one for instance when you are rested: https://patents.google.com/patent/US10789740B2/en

[tardy badger]

Lol… just had a pair of door knockers stop by my house

(I live in Utah so this means I had LDS missionaries at my door)

I very quickly say “we’re not interested, thank you bye!”

[violet parcel]

Did you wish you had star trek style forcefields ?

[tardy badger]

Yea

My corgi was trying to escape too

[violet parcel]

Best way to avoid door knockers would be to make the door unreachable so you can't hear it and have the shield that prevent this from conducting sounds

[violet parcel]

Maybe this would help

[wanton thistle]

https://tenor.com/view/youre-a-wizard-hagrid-afirmation-magic-magical-gif-16533730

Oh Idk why that has someones name

That MRI data processor though...wonder if its a mini super computer

[violet parcel]

I just find that looking at patents and linked patents generally explain things better than dry academic books in a language that non-academic can understand 🙂

[wanton thistle]

So many interesting things going on lol

[violet parcel]

Also it's real-world devices that peoples buy not "theorical" machines in a course

[wanton thistle]

lol also they labeled the patient as "Victim"

[violet parcel]

nah I added that cuz I like adding jokes 😄

[wanton thistle]

lmao

[violet parcel]

that's just a 10 sec paint thing

[wanton thistle]

"This side up"

Watching videos of people throw stuff in MRI machines was fun.

I wonder what happens if you throw a copper bar inside of one

because a magnet in a copper bar slows down.

[violet parcel]

actually you know the other fun thing about patents ?

[wanton thistle]

you can build one yourself?

lol

[violet parcel]

You wonder what the mri data processor is

[wanton thistle]

Ive found patients with the actual circuits for home appliances. That stuff is awesome

[violet parcel]

but there is 42 written next to it, which mean they also describe it sufficiently to protect it as part of the patent

[wanton thistle]

hmmm "42"

Run by Towels and a falling Whale?

[violet parcel]

no 42 refers to paragraphs in the patent

ie: 0042. The MRI system starts Parallel imaging subroutine A (step S300). The object to be scanned is placed in the MRI system (step S302). This step includes, in addition to placing the object in the MRI gantry in a manner suitable for scan
ning, configuring the MRI system for executing the scanning sequences appropriate for acquiring the desired type of diagnostic images. Configurations may include selection of prescan and main scan sequences, reduction factor associated
with parallel imaging, gradient configurations, and the like.

but in this case they dont describe the MRI data processor so they probably have another patent for it that describe it and the algorithms

[wanton thistle]

Lol, This was a reference to the The Hitchhiker's Guide to the Galaxy

[wanton thistle]

this seems like a long winded way of saying "its a digital processor that process's the raw data into human readable form"

[violet parcel]

I prefer victim to object personally

I mean they are being bombarded by a magnetic field

well they have to be verbose and specific when they describe what they protect. Writing these is the sole career of some peoples. The one registering it want to be as general as possible while the patent office want it to be as specific as possible

[spice moss]

https://tenor.com/view/showing-off-my-wand-newt-scamander-fantastic-beasts-the-secrets-of-dumbledore-looking-for-this-heres-the-wand-gif-25039801

[violet parcel]

After that they can see eh that other MRI system does the same thing as us so they violated our patent so they own us money

Basically you claim something and you use the numbered paragraphs section as a dictionnary/specification to explain what the claim mean as specific as possible

In this case they dont claim this MRI figure as an invention so they don't describe it in details, they just use it as a example of a typical MRI

[wanton thistle]

I wonder if I can find schematics for an air fryer

(Ive already taken one apart-so its a curiosity thing)

[violet parcel]

probably but for larger devices that is usually not in a patent but in trade secrets

oh btw, I wouldnt use the schematic straight if the patent is still active

because even if it's for non-profit/hobbyist the fine is pretty steep

[fierce prawn]

Does the chrome browser ble security key with phone actually works reliability
I tryed and it works with edge too

I like to imagine one day we will have a colony on an ice moon or asteroid

and computers will have the reverse problem

like you will try to make it hot enough to run

[delicate stream]

Most processors don't have cold bugs anymore

[olive dome]

I think you can move to Canada

[delicate stream]

Anything over 20K is fine

[violet parcel]

Pretty sure they have cold bugs at 50 kelvins

[delicate stream]

Not most modern Intel and AMD desktop chips. At least not as far as I know -- but it's kinda hard to get things that cold

And keep them cold

[violet parcel]

Doesn't electrons slow down as temperature get very cold right ? It's not a cpu thing it's a physics thing no?

And europa can be that cold depending on where you are same with the shadow side of asteroids

[olive dome]

So moving to Canada might be better option: you get cold enough and you also got free health care as a bonus.

[violet parcel]

Im already in Canada

and the free healthcare imply someone pick the speed for you

[delicate stream]

I mean, everything slows down when you get cold enough, lol. But once the processor starts up it can get pretty hot pretty fast, so unless you’re in a totally uninsulated environment…

[violet parcel]

sometimes that result in healthcare facility deciding your issue deserves to wait 6 hours and you just die while waiting

ie: free healthcare has issues too like the lack of choice

[delicate stream]

As much as people rag on the US healthcare system, a lot of that money goes into equipment. US has far more and far newer MRI machines than Canada, for example, so it’s a lot faster to get into a machine for a scan here

Might cost two legs and a kidney, but it’s fast and high resolution

[violet parcel]

It's the same thing with student loans in canada (I mean guaranted here)

they will restrict how much you can borrow

in the US it's far less restricted because it will be your problem eventually anyway

Also if you are the best student in Canada you only get 10000$ from the governor of canada

[olive dome]

I see, but comparing costing legs and arms I might pick 6 hours wait....

[delicate stream]

I’ve got like $32k in student loans and I dunno if I’ll ever shake that

[violet parcel]

whereas in the US you might get a full scholarship for all of university at a big university like harvard or the MIT and 500000$ in research funds/living expenses

I can name the person this happened to in Canada if you insist 🤣

[delicate stream]

Oops the brain bleed got you after 2

[olive dome]

If I got a bill of 100K then I might just be

[violet parcel]

this seems ok until you feel like you have 6 hours left to live unless you see a doctor because they didn't triage you correctly and you don't even have the option to pay a doctor 1000$ to see you right now

this happened to me before, if they had triaged me wrong I would have died

[delicate stream]

The thing with US healthcare partly comes down to insurance and how sick you are. If you don’t have a lot of problems, and have good insurance, the actual healthcare can be inexpensive

Even emergency stuff. I had to go to the hospital after a car accident, and paid nothing for the ambulance and care

Well, nothing on top of my regular insurance

[olive dome]

Yeah I agree, I'm half joking about the healthcare

[violet parcel]

also in Canada hospitals find a lot of way to make it not free

[delicate stream]

Healthcare is complicated. If you’re uninsured in the US… oops that broken leg cost $80k

[violet parcel]

like they charge 50$ to 100$ a day for a room when you are hospitalized

internet and cable costs 25$ a day

etc

[olive dome]

I have free healthcare in Taiwan also, which isn't that bad as it sounds like in Canada

There are trade offs

[delicate stream]

Mhmm

[violet parcel]

thankfully not all province are the same and I once flew to another province because I had a medical problem and it had waited for too long

[tardy badger]

Idk, I’d take Canada health care over paying $400 a month in order to have the option to have my healthcare costs covered after I spend an additional $4k for myself, and $4k at a 30% co-pay for my family until I hit my $8000 out of pocket maximum at an in network provider

[violet parcel]

I pay 200$ a month for healthcare insurance too, because anything that isn't direct healtcare isn't covered

[delicate stream]

US has some of the best medical technology, but countries like Canada are accessible to everyone. Homeless folks can get help far more easily when they aren’t turned away for being uninsured, or have to worry about having a massive bill they could never pay

[violet parcel]

Like if I break my wrist xray seeing the doctor etc is covered

but not the work after I see the doctor which cost 100$ per hour

[tardy badger]

The X-ray is like $1000

[violet parcel]

Like the professional when you using something to stretch your wrist etc so it heal over time nbetter and so you can use it again one day

not sure what is the US word but some kind of physio?

that's not covered, only my 200$ a month insurance cover such things and even then it stops at like 1000$ at 70% refund with 200$ I pay myself a year. So if it's a major injury it's going to cost me a lot

dental care is typically not covered in canada either and can run about 4000$

routine work is about 200$ an hour, most health insurance plan don't even cover it even if you pay

so yeah, I'm just saying when you say Canada healthcare is free there is a lot of ifs and but

Like I just checked similar services in new york and they are about the same prices

[delicate stream]

Oof… I have like a $10 copay for dental, and some procedures cost me like $100 (like a full root canal and capping)

But I have basic dental

[tardy badger]

My dental has a $50 deductible and covers 50% up to $2000

Im just trying to says that healthcare cost is not just the cost of seeing a doctor in an emergency room which is clearly much cheaper in Canada even taking into account the 100$ a day rent when you are hospitalized. Healthcare is also when you break your wrist playing a sport of your leg and you have to see a physio, if you break your teeth etc....

[tardy badger]

So I still end up paying $2000+ for dental work but that doesn’t cover orthotics

typically ambulance transport can cost up to 500$ as well, except for specific cases depending on the province

and typically they are not covered by private health insurance to prevent abuse

sooooo I have a 4500 deductible and I went to the ER. Definitely had AFIB and insurance didnt cover it lol

[tardy badger]

Out of network?

For me it's a bit mind-boggling though

[wanton thistle]

nope. Local hospital. they take BCBS

Like states did covid measures, but if you show up in ER with heart problems and you can't afford it they just let you die ?

That is so weird for me

[wanton thistle]

theres rules, they have to treat you

weither you can afford it, is a different matter

[tardy badger]

But they can be more judicious on the treatment if you’re uninsured

[violet parcel]

yeah but is it worth it when you end up homeless when they seize all your stuff for the 50000$ medical bill ?

[wanton thistle]

if you played Cyberpunk 2077, or watched the Anime they hit it on the mark

[tardy badger]

Like making sure to charge you for the most expensive operation when you’re uninsured

[violet parcel]

Oh also, if you aren't a canadian citizen in Canada you pay a cost like the US btw 😄

[wanton thistle]

Im not sure if they can seize my stuff, but Ive gotten collection letters. Most thats happened is my credit score took a hit of like 25 points

But like...when your credit score is in the 700s and dont need any loans, then...you know, it didnt matter

Like my girlfriend from france back then had to pay 1000 euros once just to see a doctor and get 1 xray while it's free for me (but her health insurance in France later repaid almost all of it)

If it's not an emergency they will actually refuse to see you without examining your health insurance from country with health treaties

Aesthetics are the hardest part of any project…

Opinions on sets of 4 vs. pattern of 4? I know sets of 4 is standard

[tardy badger]

Personally I like colors grouped together

[delicate stream]

I am leaning towards that, the pattern looked better in my head, lol

Also debating color order...

[crystal ore]

Heh, my natural instinct would be black-red-yellow-blue to match the visual spectrum (with black playing the role of infrared).

[delicate stream]

Lemme see how I feel about that

I think I like that

someone ever had surgery here with general anasthesia ?

[delicate stream]

Now… do I want to swap the LEDs? Lol. I’ve got blue, green, yellow, and white

[delicate stream]

I have. Waking up was kinda like sleep paralysis

[violet parcel]

for me it felt like 2 mins elapsed but 8 hours did

to this day I still feel like they did nothing and just manually advanced the time on the clock
