It was like a blackout for me, but when I was conscious afterwards I couldn't move and it took like 30 minutes to be able to mumble, lol

I think the caps can be popped off

delicate stream
#

they can indeed

#

Like initially you make you move a finger when they call your name then 10 minutes later turn your head on that side etc

#

some peoples even have very short conversation but dont remember any of it

tardy badger
#

Last time I had surgery was when I was 4

delicate stream
#

I lost like 5 minutes before my surgery and was conscious 10 minutes after they put me in recovery

tardy badger
#

Broke my arm and they had to put my elbow back together and put screws in

#

😬

violet parcel
#

yeah in these cases they dont you just you general anesthesia

#

but also something to make you forget it

#

so you dont have the trauma as your brain can still register it while you are not concious

delicate stream
#

I just had them put a balloon in my sinuses and stretch them and scrape them out

tardy badger
#

My dad has had that done a few times

#

There's an anĂŚsthesiologist on YouTube, named something like Max Feinstein, that has some detailed explanations on the subject.

violet parcel
#

maybe that's the one I saw before

#

they wake a girl and she has a breathing tube and even though it shows shes been mostly awake for the last hour during recovery phase

delicate stream
violet parcel
#

when they "wake her up" she panic because of the breathing tube

#

In my case I immediatly todl them told you the anesthesia wouldnt work because I had difficulty sleeping

#

which they found hilarious

delicate stream
#

Anesthesia is very different from sleep

violet parcel
#

sometimes for me not

#

like sometimes I dont even remember going to sleep and I wake up

delicate stream
#

I have insomnia, and a general resistance to drugs, but they were still able to knock me out

violet parcel
#

and Im like what the h!7 happened?!

#

coffee in the evening seems to knock me out

delicate stream
violet parcel
#

I live alone and doors were locked 😄

#

but when I woke up I felt someone holding me down and panicked

#

was just a pile of clohes over my sheet

delicate stream
violet parcel
#

apparently I was putting back the clothes after a laundry after drinking coffee

#

and fell into coma

delicate stream
#

that's not good

#

You should probably get that checked out

violet parcel
#

Im exagerrating with the coma

#

but for me falling asleep against my will is coma

#

but my bed is very comfortable and good at drawing me in

delicate stream
#

lol

violet parcel
#

so I guess at some point and checked if my pillow still worked

#

and fell asleep

#

these things need to be checked sometimes 🤣

late fulcrum
#

My bed is like that too, especially on cold winter nights. Not many people have waterbeds any more, but I get the best sleep that way.

delicate stream
#

lol

#

It can take me an hour to try to sleep...

violet parcel
#

My ex-boss from a few years ago had a waterbed and my curiosity about it led to an invite from her to try it during the 3-4 weeks christmas holiday, she had just changed job a week before that so she wasn't going to be my boss anymore

#

It was an innocent inquiry too

violet parcel
delicate stream
violet parcel
#

And a bit scary

#

because like what if I didn't wake up and didn't even get the opportunity to get help 😦

delicate stream
#

No wake up, no worries after that chaos

#

but hopefully you wake up every time you fall asleep for the next several decades

violet parcel
#

yeah but it would be kinda awkward

#

Like I go to sleep and I'm in an office shortly after wondering what happened

#

And the thing is like I have some good news and bad news for you

#

Your insomnia is cured

#

Id probably be like ok but I forgot to check if my stove was off can I go back for 5 minutes ?

#

I like to do joke like that when I have to provide an emergency number but people never get that it is a joke 😦

it's not as much as memory wiping as preventing memories from forming

#

basically historically when they didn't have those but had anesthesia peoples would still have nightmares even though they didn't feel it or see it

#

because they heard the sounds etc

tardy badger

I was thinking if memory wiping which is why I shared the MIB gif 😛

It takes a few minutes for it to heat up and cool down. Not sure how I knocked it off the desk, but it landed on my arm and leg DX

tardy badger
#

I can usually avoid blisters this way

#

There’s some pretty interesting research on the temperature of water to put over burns. This tends to be the most fascinating study I’ve looked into before

delicate stream
#

I did Ice cold water and I’ve got no blisters

Where do chips wear their socks?

delicate stream

On their pins, but they’re too small for regular socks, so they wear sockettes

Ok I have a 1st degree burn on my hand and 2nd degree burn on my leg

#

I may need to stop soldering without having something absolutely covering my legs

frigid tiger
#

True

#

What if they made a retractable sheath for soldering irons that were actuated by a grip safety

delicate stream
#

Having something to mechanically ensure that you couldn’t grab it or drop it on yourself or anything that it could burn would be great. Especially on monsters like this

I have an aluminium sheet 17,5 x 9,5 cm long. I stick two probes to two ends of longer length and set multimeter in 2000mV DC mode. I stick a magnet from hdd in the middle of the sheet with poles oriented to the longer length. I move the magnet back and forth along shorter length but there is no voltage produced. Why?

Is there a proper name for this type of header? I'm trying to mount a Feather RP2040 with the rest of my circuit board

#

@mystic sphinx Usually you would mount feathers to PCB's using the 2.54mm pin headers.

mystic sphinx
ebon dew
#

are the holes on your pcb offset by that distance where it needs that centipede like pin header?

mystic sphinx
#

There would essentially be a Feather-shaped hole in the PCB and then it would bridge the feather to it via pins on both sides

#

I'm working on a project where I need so keep everything as thin as possible

ebon dew
#

to sit flush just build holes on the pcb directly below the feather rp2040 holes

#

then use header pins to go straight through both pcb's

#

the little black holders around those pins you can actually move up/down or take completely off 😉

mystic sphinx
#

No i mean flush, horizontally. like the PCB on the feather would line up with the custom one

ebon dew
#

yes i'm talking about flush.

#

sit the feather rp2040 directly on your pcb

#

then push the pins in from the bottom

#

through both boards

fierce prawn
ebon dew
#

if the board is already designed with the offset then yeah nvm

#

i've never seen that header before, looks like a centipede so i'd call it a centipede header

#

i wouldn't even know how to begin to search for something like that

#

dual 90 degree header perhaps

#

At least you have tracking. My Pi 4 is out there in the ether somewhere being shrodingers package.

There are at least a dozen packages in the universe with my name on them that haven't arrived to my location

manic rain

I have two packages floating in the UPS ether

#

Ordered some prototypes for the IcyBlue add on board the TrafficWing

delicate stream
#

UPS, the USPS, and some oversees posts have my packages in their ether, lol

#

A few years ago I ordered something from China. Shipping was a Chinese company I hadn't heard of. Was supposed to be 3-6 months shipping; after month 6 I contacted the seller, they said it probably was lost and sent another. Got the replacement 5 months later, and the original still showed in transit, lol

#

I have a box full of round rare earth magnets (those black disk ones), I thought of wrapping them with magnet wrapping wire and putting them in a 3D printed ring

#

Make a little hand crank generator or something

delicate stream
#

Wind turbine!

late fulcrum
#

I think of the black discs as ceramic magnets

delicate stream
#

I didn't know there were black rare earths

tardy badger
#

That’s what the listing said at least 🤷‍♂️

late fulcrum
#

Most rare earth magnets are indeed a dark color, but are normally nickel plated to protect them from oxidation and damage.

delicate stream
#

I know the one neodynium I exploded was a nickel plate and black inside, lol

manic rain
tardy badger
#

Inductance is easily controlled by picking the turns and diameter of the coil, and wire thickness

late fulcrum
#

Current is generated by lines of force moving through a conductor. In order to produce DC that way, you'd have to arrange to have continuously moving lines of force in the same direction, which basically boils down to a continuously increasing magnetic field. It's not really sustainable.

#

In order to produce current from a sheet, you'd have to envelope the entire sheet in lines of magnetic force. I'm not quite sure what you're getting at when you say "control conductor quantity"

tardy badger
#

Put your AC signal through a full bridge rectifier

delicate stream
tardy badger
#

Throw some caps in for smoothing

#

And then have smoothies to celebrate your somewhat clean DC signal

late fulcrum
#

Maybe use 3 phases and six diodes to avoid needing so much smoothing.

tardy badger
#

Ah, center tapping. Good idea

delicate stream
#

Could you use like 24 phases for super smoothness? john_think

manic rain
#

I don't want to build an alternator

tardy badger
late fulcrum
#

Center tapping gives 180° different phase, for 3 phase, you generally want 120° so the current from one phase shows up as another is dropping off

delicate stream

Morning space creature

late fulcrum
#

The alternative to an alternator is a generator, which uses a commutator to switch coils to produce unidirectional (if not entirely DC) output

tardy badger
tardy badger
manic rain
#

just up or down

late fulcrum
#

So, reciprocating movement?

manic rain
#

like these flashlights that produce current by shaking

tardy badger
#

Like a shake weight

late fulcrum
#

Yeah, that's the magnet in a coil I mentioned previously

delicate stream
#

Shake light

manic rain
tardy badger
#

I think with a coil like that you have to use a full bridge rectifier since you’re current direction is going to change

late fulcrum
#

That would be considerably less efficient

tardy badger
#

Unless it was a ring magnet

#

Fulling encircling the coil

#

But ring magnets are expensive

manic rain
late fulcrum
#

It still would be a less concentrated magnetic field, compared to a magnet within the coil (where all the coils' fields overlap)

tardy badger
#

Why can’t you put the magnet in the coil?

#

From a space perspective, that is a much better design

manic rain
tardy badger
#

I don’t see how that changes the constraints if you do it right.

late fulcrum
#

You say you don't need rotary movement, but you're on a rotating wheel? Colour me confused.

tardy badger
manic rain
tardy badger
#

You could place coils on the frame and put thin magnets around the frame if the tire, alternate polarity

late fulcrum
#

That's how the alternator in my tractor works

#

Actually the other way around, there are stationary coils within a rotating magnet array

tardy badger
#

Am bad with the words

manic rain
#

magnet will have poles oriented along the spoke. On the frame there will be coreless coil, will movement of a wheel produce DC?

late fulcrum
#

Can't get DC, sorry.

delicate stream
late fulcrum
#

I would also suggest having a core in the coil to concentrate the magnetic field.

#

Perhaps a U-shaped core with the coils on it, and the magnets going past the open end. That would give a series of pulses, one positive and one negative, each time a magnet goes by.

wanton thistle
manic rain
late fulcrum
#

This is why coils are popular: more turns gives more voltage

wanton thistle
#

and run it backwards as a generator.

#

I thought this was a "I want to experiment" thing

manic rain
late fulcrum
#

It still won't. As each magnet passes, the field increases for a bit (producing a positive slope), then decreases (producing a negative slope), so the resulting waveform is a series of pulses.

manic rain
late fulcrum
#

Yes.

manic rain
# late fulcrum Yes.

would it produce DC if I turned a rear wheel to a reverse homopolar generator meaning that there would be a magnet with poles oriented along the hub, two coils on both ends of the hub connected by axle and by the fender with LED

late fulcrum
#

I don't understand what you're describing, but the basic concept is as I outlined previously: to produce DC you'd have to have a continuously increasing magnetic field, which is unsustainable.

manic rain
late fulcrum
#

Huh, didn't know about that one.

delicate stream
#

I don’t think you can make that happen with a bike wheel tho

#

Not easily anyway

#

Plus an appropriate disk mounted on the wheel might be prone to damage

manic rain
delicate stream
#

I think you’d still need to have a disk that might be prone to damage — even if the disk is stationary, I think you’d need the magnet on both sides of the disk, and if it becomes misaligned, it’ll damage everything

tardy badger
#

Just based in reading that Wikipedia article, I don’t think it would be practical to implement on a bike

delicate stream
#

Not sure it would withstand the forces it would experience on a bike

tardy badger
#

Right

delicate stream
#

You’d probably want to drive it by a gear rather than by the wheel itself anyway

tardy badger
#

Most wheel generators sit at the axel level

late fulcrum
#

I'm used to the ones that just have a friction drive from the tyre itself.

tardy badger
#

Yeah

delicate stream
#

Friction drive is fairly common

#

Or at least it was, lol

#

Very easy

manic rain
late fulcrum
#

Not really, it depends on what factors you're optimizing for. For some parameters, it's pretty good.

delicate stream
#

Why terrible? Works well enough

tardy badger
#

Bikes are just odd machines to try and fit electric generators around

manic rain
delicate stream
# manic rain not in wet conditions...

Most bike lights that use friction generators do fine in the rain. It’s not smooth surface friction, they’re kinda toothy and press into the rubber. No worse than the wheel to the ground for friction

native barn
#

just put my old adafruit product stock monitor up on github

#

do any of you guys want it

late fulcrum
#

I could imagine a toothed tyre that gives particularly good traction, but I'm not aware of any being actually produced.

manic rain
native barn
#

does that violate tos

late fulcrum
#

Yeah, that design is what we've been describing, and you've linked to it before. If that's the one you want, go ahead and build it.

delicate stream
late fulcrum
#

Granted, "frictionless" doesn't mean "free power", there's still drag on the wheel, it's just magnetically coupled drag.

glossy knoll
#

Can you make one using ice? According to my introductory physics books, ice is frictionless 😁

manic rain
#

is it true that amps produced by an alternator depends only on load?

tardy badger
#

@late fulcrum to circle back to our EMI discussion a few days ago. I wanted to see in open air what the most dominant frequency emitted from the crystal area of my fpga feather was, it looks like the dominant frequencies are between 19.5MHz and 20.5MHz which is interesting given the crystal is a 12MHz and those frequencies are not really in the major harmonic range for 12MHz frequencies.

late fulcrum
#

An alternator produces voltage, then the load pulls amps from it, so the load does sort of control the current drawn, but not "only", as the alternator does have a source impedance as well (additionally field coil alternators can vary their electrical parameters)

late fulcrum
tardy badger
#

I think that is likely the case

late fulcrum
#

The data sheet might provide some explication

tardy badger
#

It might also be ringing for some sub frequency groups which is an interesting thing I didn’t think about

#

Given I don’t have a very tight power ground loop around the crystal

late fulcrum
#

Hmm, you did intentionally make the traces short, so I wouldn't expect much ringing from the signal traces but you're right, the power traces might be contributing. Since they're (presumably) planes, I wouldn't expect them to have much Q.

tardy badger
#

There might also be some environmental dampening which would probably be more evident in a controlled environment

late fulcrum
#

I often put guard rings around crystals, but that's more to protect the crystal oscillator from interference than the other way around, but it should help with both to some extent.

tardy badger
#

It could be higher level harmonics from the USB cable that’s plugged into my desktop too

late fulcrum
#

You could build a sensor probe and see if you can localize the source/orientation/polarization

tardy badger
#

Yeah, that’s a good idea

late fulcrum
#

Technically, you could buy one, but I consider that economically perverse.

tardy badger
#

Yeah

#

The 3.3V power rail would likely produce some interference and the LiPo chargers also will as well

#

Usually starting at the 100kHz range

late fulcrum
#

I had one board that clicked when one of its 3.3V supplies was enabled. I eventually traced it down to a particularly piezoelectric capacitor, by dint of using a mechanic's stethoscope

tardy badger
#

So like a 45th harmonic of 100kHz is ~20MHz

#

But that seems too far high in the harmonic range to be plausible

#

But maybe not if the frequencies get coupled

#

🤔

#

Oh well, it appears at least in open air that the EMI from the board is negligible

#

The ~20MHz noise emitted is like -85dB less than 10mm away

#

Seems pretty good to me

late fulcrum
#

Yeah, unless you have some frequency multiplying effect (like a step-recovery diode), some sort of resonator at a particular harmonic, or Barkhausen oscillation, normally there isn't much harmonic energy after the first 10-20 (depending on risetime, etc.)

late fulcrum

There are advantages to ordering in bulk. Not tempted to Muntz away the 0Ί resistors?

tardy badger
#

I’m using 8x 4.7uF caps in my fpga board, so I’ll get… 100ish boards

tardy badger
#

I figured the 200ohm was too strong, if people want to tamp down the RGB brightness they can replace the 0ohm with something between 0 and 100ohm

#

how does one go about checking whether a building's electrical ground is intact, i.e. reaches all the way down? My vague understanding is that this must be checked every few years, at least for some types of buildings in some cities.

late fulcrum
#

Beats me

wooden schooner
#

looks like the main thing i was looking for is the "fall of potential" method:
(from https://www.dfliq.net/blog/ground-testing-in-electrical-maintenance-the-what-why-and-how/)

The fall-of-potential method is typically used for testing individual grounding stakes or grounding systems as a whole. It measures their capability to dissipate electricity:

The stake which is being tested is first disconnected from the system.
The testing apparatus is connected to the disconnected stake, now called the Earth electrode.
Two other stakes are embedded in line with the first electrode (outer and inner stake).
Once the ground tester has been connected to the two stakes, a known current is released through the outer stake and Earth electrode.

The distance between the outer and inner stakes depends on the electrodes’ length. You can refer to a guide or a chart to check how you should install the stakes.

#

maybe the "known current" would have to be pretty high to distinguish between a floating ground (metal building frame) and a true ground if the building is large? not sure how to estimate that

delicate stream
#

Too bad you can’t just stick a stake with a wire in the ground outside and use continuity on your meter between that and your AC ground pin

I don't know what it does produce; I have the feeling it'd be represented on a graph as a curve, and at some point the motion ceases, and there's likely some form of collapsing field to account for.

I would just hook up rectifiers and measure to see what it does produce.

I don't believe a homopolar generator like this operates in a pulsed mode. They can be used as pulsed power sources, but that's if you spin up the disk first and then dump all the energy at once. If you keep rotating them, they just keep producing voltage.

Unfortunately, I'm still too tired. I suspect your answer lies in the library itself, which is presumably getting the raw values from the device, doing something with them, and returning them to your code.

I think micro mod is pretty set in stone

It could really be whatever you want it to be as long as it’s compatible

quasi wolf
#

Not if the person designing the carrier board hasn't left space for it.

#

I'm constrained by their design choices

tardy badger
#

then it's not compatible

quasi wolf
#

That's why some tentative agreement 'let's go wide by default' or let's go long by default would be good.

tardy badger
#

but look, feel free to add your comments on the issue, last I saw it hasn't been active in a while which likely means there isn't much intention to try and make a standard

#

I would venture it would probably be better to reach out to SparkFun and see if they'll publish a standard for the MicroMod since they originated it.

quasi wolf
#

They have published Micromod, It's just too small. Which is why I'm interested to explore the best way to get larger boards.

that might end up being a solo venture. though feel free to ask on Desk of LadyAda. it'll probably air early morning your time.

#

How can I protect a motor from failing when something doesn't let it mechanically move?

#

I have a motor in a circuit where it's just a switch with batteries, and I noticed it's really sensitive to something stopping it from moving. It will just halt and not move anymore for a little while if something blocks it

#

I'm thinking it's because when something blocks it, its impedance sharply declines and it has to eat a lot of power it's not comfortable with. Would adding a resistance in series help?

half plank
#

Are there any downloadable physical stackup for a rigid flex pcb?

late fulcrum
hasty quarry
#

What really happens to a motor when it's mechanically stopped?

#

Am I right in thinking its impedance sharply declines?

late fulcrum
#

Yeah, there's less back EMF in the windings, which appears as a reduction in impedance. Some motor data sheets will list the "stall current", which is the current drawn when the motor is not rotating.

hasty quarry
#

What causes the motor to get "exhausted" and not run for a little while when it stalls for a bit of time?

late fulcrum
#

I'm not sure what you're describing

hasty quarry
#

And when I let it go, it’s still stopped, not moving anymore even if I cycle power

#

When I cut the current and give it some time, it works again

thick wind
#

It could be a resetting fuse inside the motor, breaking the circuit when the stall current overheats the fuse.

whole jacinth
#

yeah, self-resetting thermal protectors for motors are a (common) thing

ebon dew
# hasty quarry When I cut the current and give it some time, it works again

Sounds like either a thermistor is turning it off or over current from high resistance. It's a safety mechanism to prevent your motor from burning up but it depends on the motor. For an electric car not that big of a deal, for an airplane or 3d printer it's a big deal. Depends on the application if that kind of thing is a desired feature or not. Motor turning off is usually a symptom, not the culprit.

#

The only way an overheating motor will turn off (other than some built in safety mechanism) is thermal expansion causing a break in the coil windings, which definitely happens with automotive alternators. They heat up, expand, a fracture becomes a gap, alternator breaks. It cools down, gap returns to a fracture, and works again... rinse and repeat infinitely.

if I get Adafruit's DIY USB A Female Adapter how I can convert a standard USB-A to female? just wire the same pins as the DIY Adapter?

ebon dew
#

yes, usb a is fairly simple to wire up

#

you'll probably want a magnifying glass though, those wires can get tiny depending on your eyesight.

#

but if you're going for minimal space constraints the DIY plug end is the way to go.

brave copper
#

it's for the 3d printed bracket of the BMC64 I have from corei64 my hdmi adapter for pi zero is hot glued to the position of the video port would been and with an female shell diy one I could do the same for where I want my usb in place of the serial port will go.

I'm replicating these ports by using adapters even if it's a female to male adapter and I could hook up Adafruit's DIY USB ones with ribbon cables

brave copper
#

so this is how I gonna do it

The HDMI Pi Zero Micro hdmi to HDMI adapter became my own HDMI Video Port and now once I have a good USB Adapter to use that fit into the 3d print's space I'll make it as the Serial port

ebon dew
#

is this for an enclosure? i usually use panel mounts. they can be screwed to an enclosure.

#

though anything with a pi zero is probably going to need a small solution.

brave copper
#

It's a 3d printed bracket that covers the bread Bin's ports

#

doesn't work I'm not that ohh put it where the userport used to be

ebon dew
#

ah yeah the DIY seems most logical for something like that

#

if you design the 3d printed cutout just right the DIY connector should work fine. add strain relief by tying the cable in a knot.

brave copper
ebon dew
#

ah a knot won't work with a ribbon cable. hot glue it is then 🙂

#

you could go from your DIY connector to a panel mount 😉

brave copper
#

well I can get an adapter of the DIY shell and just recreate the usb by putting thr wires on the right pins and boom a female to male usb-a then hot glue it where I want the adapter in that area where is shows S and make that hole for the usb to be in place.

I'm making my BMC64 to feel like it's a REAL C64 inside but it's not

ebon dew
#

i see, tough choice. i think over time the hot glue will become brittle and you'll have to redo it.

#

years later but still, a panel mount is more permanent.

brave copper
#

I had no issue of the hdmi adapter coming off I make sure it's really globbed

ebon dew
#

if it works it works 🙂

brave copper
#

I had to to hot glue one of my 2 x 4 green lego bricks close to the BMC64 Board that connects the DB9 ports, LED, C64 Keyboard, usb for power jack so it holds if I need to plugin a joystick to the ports

ebon dew
#

you have a 3d printer...

brave copper
#

wish I did...

ebon dew
#

ohhh just the bracket is 3d printed, i thought you meant you printed it.

#

now all the bodges make more sense.

#

you do what you can with what you've got. if it works it works.

brave copper
#

the whole bracket is made by Corei64 - this store makes them for pi mounting in a breadbin, a vic-20 or the C64C cases I choose the breadbin for a CLASSIC styling for my BMc64 emulator

#

it's a weird project of mine....I take any Bare Metal Emulator made for the Pi like let's say someone made the Apple ][ emulator for pi that runs without an OS then to make it feel like the real computer - I find the parts for it to make it work like it had a case and a keyboard.

so once I have the parts I build my own ports and other stuff inside the case or find PCB Boards that help the pi to use the keyboard and other stuff the emulator seeks to help it feel authentic.

Finally

#

Gotta clean the sticky residue on the piston ribber

#

*rubber

#

cleaned

#

Should i lube it

#

but it wiil suffer from the same issue though

ebon dew
#

rubber seals always work better with a very thin layer of lubrication. the lubrication you use depends on the material of the seal.

#

do not use petroleum based lubrication on petroleum based rubber gaskets or seals, it eats away at it like acid.

#

for petrolum based seals use silicone lubrication

fierce prawn
#

just pure rubber

#

so wd40?

ebon dew
#

wd40 is petroleum based, its safer to go with silicone even for natural rubber.

#

don't get me wrong wd40 will work in the short term but if you intend on using that seal for months it might degrade the longer its in contact with the wd40.

fierce prawn
ebon dew
#

that's usually the case, you can usually find a small bottle of silicone lube at any automotive parts store

fierce prawn
ebon dew
#

wd40 also makes a spray on silicone lubricant

#

i've never even thought of cooking oil, no idea. i suppose olive oil would work.

#

yeah any cooking oil should work, there's no way they'd put petroleum in cooking oil

fierce prawn
ebon dew
#

maybe, i have no personal experience with it. do some research.

#

looks like vegetable is a perfectly good substitute

fierce prawn
#

so i shouldnt put mineral oils

ebon dew
#

kind of why i recommended silicone, it's the right tool for the job.

fierce prawn
ebon dew
#

sounds about right

#

wd40 silicone yes

#

wd40 has many different varieties

fierce prawn
ebon dew
fierce prawn
ebon dew
#

make sure it says silicone on the can

#

regular wd40 is petroleum based which is great for metal on metal gears. it's not good to get it on rubber gaskets. that's when you switch to silicone lube.

fierce prawn
#

so what should i do
no oil allowed and if my wd40 isn't silicon
should i just left it unlubed cz i guess my friend used the wrong lube

ebon dew
#

can wash really well with dawn soap and that'll get most off. then let it dry and relube with silicone.

fierce prawn
ebon dew
#

silicone lubricant and silicone caulk are 2 very different things by the way even though they share the same name.

fierce prawn
#

unlubed is a pain

#

to move the cylinder

ebon dew
#

yes, that's why lubricant is recommended 🙂

#

just a very light coating running your finger around the outer edge is all that's required, don't slather it on there.

fierce prawn
ebon dew
#

i would actually spray some on a paper towel and run that around the ring

fierce prawn
ebon dew
#

if the plastic is petroleum based only

fierce prawn
ebon dew
#

which most plastics or 3d filaments are not

#

lego is ABS and has petroleum based additives so yes wd40 can degrade lego

fierce prawn
#

close it and use it unlubed or dig my parents tool drawer?

ebon dew
#

just wait until tomorrow and ask them to get you some silicone lubricant. it's about $5 from any automotive parts store.

#

you don't need the wd40 silicone, that stuff is actually much much more expensive.

#

$5 from walmart

#

works better than before cleaning and without lube

#

now just how to glue the top back

ebon dew
#

for automotive uses it's commonly used in the process of changing brake pads on a car.

#

$8 from any automotive store

fierce prawn
#

just found some and lubed it
the top snaps back it so no need to regule?

it's your project i have no idea, if it works it works.

fierce prawn

I just realized that it's a good thing that Doc Brown had a car from 1985 that went back to 1955 -- if he'd used a car from today still running on fossil fuels, it wouldn't run on 1955 gas

late fulcrum
#

There are some flex fuel cars available today that probably would

delicate stream
#

Would they? I thought all modern engines were designed expecting E85+, as well as not being designed to handle leaded gas

#

I think the lead would be damaging to engines not designed to run on it

late fulcrum
#

There are modern engines designed for E15, and a few other variants (and here I'm ignoring outliers like gas turbines and the like, which will run on nearly anything)

delicate stream
#

... Do you think we can make 1955-style leaded gasoline to test?

late fulcrum
#

Should be doable, the federal gasoline regulations in those days should be fairly specific. You did have a choice in those days of "ethyl" and non, so there was unleaded gas available (generally fairly low octane). If you did want to try with leaded gas, it is still available for some specialty markets today.

delicate stream
#

Oh, I didn't know they had unleaded gas in the 50s! I'm guessing markets with leaded gas are outside the US

late fulcrum
#

Even in the US, there are some racing and aviation fuels with lead

delicate stream
#

Ohhh.... should be easy to test then

#

We just need someone with a 2020s car who's willing to risk engine damage XD

late fulcrum
#

My understanding is that engines designed for unleaded will generally run fine on leaded, but the other way around is less true: older engines depended on the lead for various lubrication and sealing effects. Modern engines also have to deal with water (from ethanol) and its effects on seals and gaskets, and again older engines can suffer when using modern fuels.

you need to choose the lube carefully
clean the case inside and the oilly rubber lube
then sand the steel stick
then apply lube to rubber then close it all up
theres still a little bit of rust

I’m really beginning to wonder if ups doesn’t understand 2nd day air 🤔

#

Ordered another package over the weekend with 2nd day air (expected today) and it’s in Kentucky somehow

#

Adafruit package shows it’s still in Illinois.. also was projected to be delivered today

#

le sigh

tardy badger
#

I feel like one place AI could really succeed is pulling weather data for a region, analyzing it based on current routes for packages and then push updates to tracking numbers about potential weather delays rather than letting customers think “my package is on time and will make it!”

#

And then! Based on the data generated, if a hub doesn’t receive a package incoming within the normal window, it automatically updates the tracking with a delayed stamp and the accumulated information like weather, or accident data.

late fulcrum
#

I was hoping for similar functionality back when I commuted. I wanted to ask "Which bus stop should I head for to get to Arlington soonest", and it would take into account the bus and train schedules, as well as how full the lots are, how long it takes to drive to each one depending on traffic, and confounding effects like weather (certain lots fill up quickly at particular times when it rains, for example).

tardy badger
#

It is really interesting that we live in a world that aggregates so much data yet we’re not really using it in meaningful ways. Instead we get ChatGPT

#

Lol

#

Totally agree. It's like in Who Framed Roger Rabbit, when it eventually comes out that the toon physics only works "when it's funny".

#

The cynical side of me is left pondering the usual questions like "who profits from making public transit worse?"

tardy badger

late fulcrum

That said, I am accustomed to better service and more transparency from UPS. I expect shenanigans from the likes of FedEx and DHL (although to give credit, DHL did eventually provide a surprising amount of access, clarity, and actual improvement when a youtuber used some Airtags to show that the tracking information they were providing was bogus)

#

Come to think of it, one of the themes in Roger Rabbit was forcing people to use "Eight lanes of shimmering concrete" instead of the Red Car trolley.

tardy badger

Yeah, great symbolism for the great American independent citizen

What if VTuber who does just electronics junk

But anyway, how would VTubing work if you are making physical stuff?

#

Well, I imagined something basically like what Foamyguy does, but VTuber face... and maybe themed gloves for hands on the downshooter?

#

If the character is a robot, maybe robot gloves, lol. Unless there's software that can track and overlay hands the way they can for faces

I’d be curious to see what happens

VTuber stands for "Virtual YouTuber", basically a virtual character that generally overlays a person's face on camera

Wow, I've never heard of that. Seems random and bizarre to me, but apparently it's a thing.

Yeah, the channels I watch tend to consist of people tearing down electronics, engines, turbines, etc.

#

Oh, and locks 🙂

delicate stream
#

The Venn diagram of those channels and common VTuber topics are kinda not overlapped much XD

#

I might become the first teardown and electronics VTuber

late fulcrum
#

Exactly. Since a virtual character doesn't really add much information to a data stream, it's not the sort of thing I would seek out anyway.

delicate stream
#

Depending on the teardown, the person [or character?] doing the teardown may be super important. Imagine LPL's channel without the sass and charm he brings, or BigClive's videos without the booze-enhanced personality XD

late fulcrum
#

You never see LPL's face, which sort of illustrates my point: I'm there for the content.

delicate stream
#

True... just his hands

#

I guess BigClive is a better example, sorta? you only see his face sometimes...

#

But yeah you're not the target audience XD

#

But I assume you'd not avoid something like LPL with a fun virtual character

#

If the content itself is good

late fulcrum
#

The algorithm tries to recommend the "joke" or "work story" videos where there's scrolling text, and a (real or synthetic) voice reading it. I have no patience for those, I could just read the few hundred bytes of text much faster than watching the same material more slowly, packaged in a 10 megabyte video.

#

I don't know, I'm not sure what the virtual character would add, and if it's eating up screen area without adding value, I'm going to object to it (see pretty much Edward Tufte's entire body of work about making best use of screen real estate)

delicate stream
#

Some of those [especially synthetic] are worthless. But some of them definitely add to it, lol

#

Funny voices and stuff

I did watch a series of Hot Wheels restoration videos, not because I have any interest in Hot Wheels, but because the videos were so well made. No music, no time waste, just well modulated voice and excellent cinematography.

Hi everyone,
For my master thesis at Leiden University I am researching the risks involved in contributing to OSS for businesses and more importantly: how to reduce those risks. With this research I hope to encourage more businesses to participate in OSS. For this research I am looking to interview software developers (or those in similar roles) who contribute to OSS projects as part of their job. More specifically I am looking for those who contribute to OSS projects that were not originally developed by their own company. If you fit this picture and if you are interested in participating in this study, please let me know! The interview will take at most an hour (we can plan for shorter as well, although at least 30 minutes would be preferable). If you would like more information or if you have any questions do not hesitate to shoot me a message or email me at okkemoison@outlook.com .
Sincerely,
Okke

to each foot

#

then put them back on and adjust them

move the nut up to where the screw touches the screw hole thing and tighten it

if you tighten it enough it wont come loose

whole jacinth
#

yeah you can sometimes buy special thin nuts called “jam nuts” that are useful for locking screws/bolts against vibration this way @dusty citrus

tight copper
#

if we add an nvidia newton we can use machine learning to predict where it lean next and prevent it

#

we could add a lidar sensor to to map the entire washing machine and adjust the screws during the washing cycle to reduce vibration

#

then we can add an oled touch screen with graphs showing data from the last wash

#

if we continue down this road eventually we will eliminate all vibrations and reach 0 kelvin

Should be doable with simple wire antennĂŚ if it's line of sight, maybe slightly fancier ones if not line of sight. I was easily able to get 1100 meters out of a pair of them with wire antennĂŚ (although that was with the 432MHz version)

One nice thing about LoRa is you can trade range/reliability for bandwidth. Since you're sending a tiny amount of information, you don't need much bandwidth.
