[tardy badger]

Oh yeah

[rapid geode]

but... i take everything he said with a grain of salt cause... purple enzo. PURPLE (yes, its real, i saw it in real life)

[tardy badger]

Why does this look photoshopped

It feels like such an unrealistic shade of purple

[rapid geode]

yes. its very very werid

and not a wrap

[late fulcrum]

I would totally do that

[rapid geode]

ha

i cant find any reference to it being a factory paint, so i guess it had someone local do it here

i never asked

(i dont like him haha)

[tardy badger]

I bet Ferrari banned them from ever buying another one lol

[rapid geode]

ha. maybe

[tardy badger]

They have done that to people, black listing them because of things like wild paint jobs

[rapid geode]

(not to get itnto it, but thet family didnt have any money... or freedom - shortly after)

[tardy badger]

💀

[rapid geode]

just googled it. "aquitted". ok. :x

(dont want to say the wrong things)

[tardy badger]

Feel free to dm it to me

I’m curious lol

[rapid geode]

nah. its fine. its more about making sure i dont say things that arent public. but i guess its all public now so no big deal

[tardy badger]

Ah okay

What do I google?

[rapid geode]

no, i mean I googled

to see

ha

[tardy badger]

I know but I’m curious lol

[rapid geode]

race car drive named andrew bordin. his family had a billion dollar company and lost it all charged with fraud etc.

andrew himself was just a spoiled rich kid

he crashed a pace car and broke his neck

[tardy badger]

Geez

[rapid geode]

his career kinda died off after that. (he did recover, but i guess not as good any more?)

he was expected to drive indy before the accident

anyhow

i did web/marketting stuff for him. he was a bad client

hahaha

i think the purple enzo was technically his fathers

[tardy badger]

Kids, skating off their billionaire fathers coattails

[tardy badger]

Ah I see

That was a while ago then

[rapid geode]

ah yeah. ages ago

haha

[tardy badger]

I was like about to turn 8 when that article was published

[rapid geode]

hehehe

he was 19 or 20.

[tardy badger]

I was more concerned with pokemon or whatever game I was playing at the time

[rapid geode]

hehe

my companie was doing some f1 related stuff, so somehow he came to us.

[tardy badger]

Probably grand tourismo

Or GT2 at that time because it had recently come out

[rapid geode]

hmmmm

2 maybe

[tardy badger]

GT2 came out Dec 11, 1999

Wow

I had a souped up 1998 Toyota Supra with 908HP 😂

Fun game

[rapid geode]

hahaha

i always liked the r34

[tardy badger]

The NSX was also a fun car to drive in the game

GT3 is a game I also spent a lot of time on

Then the GameCube came out and I played a lot of Sonic Adventure 2 Battle, Sonic Adventure Directors Cut

[rapid geode]

ha

i never played many games

gt2 was one

[tardy badger]

Oh nice

[rapid geode]

oh, and halo, but only to shoot my friend and annoy him

:x

my next world domination plan

muhahaha

:x

(its too big for my cnc)

[tardy badger]

Oh nice

[rapid geode]

little kid sized guitar. kinda like a ukulele, but not quite

i need to make 10 or so in the next month. trying to figure out how. ha.

the small parts are easy

i designed that fixture in the pic for the neck, but im not sure it will work well

[burnt tendon]

I can see how you'd fret about getting it wrong, tho.

[rapid geode]

[patent hemlock]

aw, don't let wirehead pick on ya! 😀

[strange sonnet]

What's the difference between a ukulele and a small guitar

[glad ruin]

https://media.discordapp.net/attachments/1086654272688623748/1237481709574951043/desconhecido.png

[fast ferry]

you can git yerself a ukelele, but you can't uke yerself a guitar?

[rapid geode]

nothing? it gets murky. generally though each has a specific type of tuning. thats the most critical difference. but there is a ton of overlapping. a lot of people tune ukuleles like guitars.

[patent hemlock]

i think it has to do with tuning and a certain style of playing the instrument

[strange sonnet]

Is the difference the number of strings

[burnt tendon]

Of course the number of strings makes a difference.

(that was a pun)

[ebon dew]

You can dampen the echo chamber of a guitar to sound like a ukelele but you cannot make a ukelele echo chamber bigger, if you did, it would be a guitar.

[rapid geode]

no, cause there are 3, 4, 5, 6, 7, 8, 9, 10 string guitars. and 3 and 5 string ukes.

[rapid geode]

yeah, but there are 1/8 scale classical guitars and they are still called guitars despite being the same size as a tenor uke

at some point it's just words i think

(mine is between a tenor and concert ukulele for scale/size)

what it ACTUALLY is, is a fender guitar scale cut at the 8th fret with 2 strings removed.

this is my electric version. slightly larger with 6 strings.

[dusty citrus]

Don't forget about the Banjo. And the Banjo Uke. And the Banjo Guitar...

[tardy badger]

And most importantly, banjo kazooie

https://tenor.com/view/banjokazooie-tada-hey-nintendo-64-gif-11667654

[strange sonnet]

The one I got was called a Banjolele. Maybe that's a brand name

[patent hemlock]

feh - there's this thing

[strange sonnet]

That's for when you have 6 people in your band but only enough money for one instrument

[whole jacinth]

or your guitarist is an octopus?

[dusk flax]

I'm trying to imagine 6 people playing that at the same time... It's not working

[stoic mesa]

[rapid geode]

a banjo is more about the body resonator / drum.

[scarlet herald]

hi

[drowsy zephyr]

guys
does anyone know of any good laptop based electrical engineering activities I can do at my down time? something that doesn't involve reading or lectures?

[reef bobcat]

FYI - the version of of tio you are using is too old. You need at least tio v3.0 which introduce the '--auto-connect latest' feature.

[reef bobcat]

Maybe learn how to design electrical schematics and PCB loyouts using the Kicad EDA - https://www.kicad.org

[drowsy zephyr]

that needs a project, anything more grunt-ish?

[reef bobcat]

Well, Kicad is always looking for people to help add to and improve their component libraries. That is grunt work.

https://www.kicad.org/libraries/contribute/

[drowsy zephyr]

i see

[reef bobcat]

FYI - for those in here that uses tio. I've just released tio v3.2: https://github.com/tio/tio/releases/tag/v3.2

[urban arrow]

Full confess. Man am I lazy. I've coded many projects, some right out of the learn guides of course with changes, and get to the wonderful "It's working!" stage. Then, oh, I'll clean up the code, break up into nice functions, etc. "some day". Some day never seems to come. 😒

[patent hemlock]

yep -- i endlessly tweak things and all the refactoring is going great and then squirrel and off in another direction

[urban arrow]

Doesn't help The Lady keeps releasing new shiny toys... or JP does a Product Pick I must have...

[thick wind]

At least you got to the “it’s working!” I’ve been so busy I haven’t actually done any of my projects…

[tardy badger]

I feel like I’ll get something mostly finished but never have the time or energy to actually fix issues

Plus there’s also needing to have to money to actually get the parts to fix whatever issues I run into

Lots of half baked projects that probably won’t ever get finished

[ebon dew]

It's easier to finish projects if you turn them into PCB's. My personal opinion is if you have a breadboard full of wires for a project it means that a PCB does not exist for what you're prototyping and should eventually become a PCB. Otherwise that breadboard full of wires tends to stay that way.

[patent hemlock]

heh - my problem is not wires per se: i've gone down the I2C route so i have 💩 everywhere and 4 raspberry pi to run them all

[thick wind]

I don’t even have modules wired yet. Admittedly, a large portion of my boards are still in their original packaging.

[tardy badger]

I have.. plenty I’ve turned into PCB that still need debugging, respinning, parts.. it’s a struggle

[patent hemlock]

my back wishes it had ignored that advice 😏 👴

[rapid geode]

actually that first one is quite unhealthy

:x

[tardy badger]

My wife was doing the math on the average change in price from 2021 to 2024 for the things we typically buy. Typical fixed cost items cost $1.10 more.

[rapid geode]

on what though. need a percentage

[tardy badger]

Prices basically doubled

We’re talking items that were $0.60-0.80 costing almost $2 now

[rapid geode]

ahh

what costs 60 cents ha.

[tardy badger]

It’s no wonder it feels like I’m getting half of what I used to

[rapid geode]

i guess a lemon or an apple?

[tardy badger]

Cans of beans

[rapid geode]

ah

[tardy badger]

Or microwave pouch of veggies

[rapid geode]

a can of peas is.... um. i dont remembe rnow. i wanna say $1 still

i dont buy much canned things

[dusty citrus]

Smuggling basic necessities to the us, seems to be a great business.
Except that's expensive and stuff rots

[tardy badger]

My kids all have milk allergies/intolerances. My youngest son was on soy formula in 2022 that cost $14 a can, it costs $27 now

[rapid geode]

the things ive noticed the most is cheese and meat is a roller coaster

eek

[tardy badger]

Yeah

[rapid geode]

this year my peach budget will be $0

woo

haha

[tardy badger]

My daughter who was born in March is also on soy formula and the cost is painful

[rapid geode]

so cant even do human milk?

ugh

[tardy badger]

Luckily after 6 months you can start introducing puréed foods

[glad ruin]

Oh yes, and I'm sure your insurance is definitely helping and not making your life miserable at the same time (not).

[tardy badger]

If my wife went completely lactose free and was actually able to produce, maybe

[rapid geode]

ahhhh

[tardy badger]

But we found that my youngest two have milk protein issues so lactose isn’t even the issue

[rapid geode]

milk prices here are fixed, so thats one thing that has not changed dramatically

(unless you want fancy milk)

[tardy badger]

A gallon of milk here is $2.63, it’s the only thing that’s $0.01 cheaper than 2021

[rapid geode]

ah, ok. looked it up. peas in 3 for $5. shrug. i dont remember what it was before though

ha

[tardy badger]

Some things are only marginally more expensive like frozen veggies are only up $0.12-$0.50

[rapid geode]

4l bag is still about $6 here. it was 5.50 before pandemic. and 2.99 in the early 80s. it really has not moved much

relative to everything else

[dusty citrus]

Ah. Here 1L of milk ranges between 1~4€, not so cheap

[rapid geode]

cheeses though are not fixed, so they have gone nutso

[tardy badger]

Yeah, we spend like $0.75 per litre

Costco cheese has been fairly stable

[rapid geode]

i buy 2L milk cartons of the fancier filtered milk. thats $5.

[tardy badger]

But the average pack of presliced here is up $0.25/pack at least

[rapid geode]

i buy it cause i cant drink all that in 4 days

haha

[rapid geode]

im paying $10 for 280g of cheddar

bleh

costco has deli blocks, but again i cant eat all that so its not of much use

costco has whole parmesan wheels

hehehe

$700

sometimes i find ribs for $2/lb. but then other days its $12. chicken too. $14 for 2 breast one week, $3 the next

so erratic

"lowest price in years"

oof

haha

[tardy badger]

Wow

[rapid geode]

actually, theres some really good sales ending today. ha

$3 for milk

$1.80 for pasta. hmmmmm

[tardy badger]

I’m sad a bag of chips has gone up over a dollar since 2021

$2.89 for a normal bag up to $3.89

[rapid geode]

a bag of doritos is $5 here now

[tardy badger]

I don’t eat a lot of chips but it hurts now

[rapid geode]

yeah 389 sound similar

i dont know the logic

have potatoes and corn gone way up?

i supposed like with pop a large amount of the cost is shipping

i planeted lots of corn this yeah. hope it grows well

2 pumpkins have sprouted too

mmm

[tardy badger]

My pumpkins are already trying to make babies

[rapid geode]

nice

[tardy badger]

The plants are fairly small too which is what makes it funny

[rapid geode]

these just sprouted yesterday

i planted 12. 2 up so far

5 or 6 would be good enough as long as the squirrels dont eat them all

[tardy badger]

We got really close to a frost overnight, hopefully no more cold fronts till October

[rapid geode]

oof

yeah our last cold overnight was about 2 weeks ago

[tardy badger]

We had a stray cold front come thru after it had been in the 50s (11-15°C) at night

[rapid geode]

AH

last year we had a freeze after my peaches bloomed

[tardy badger]

But that’s “springtime in the Rockies.”

[rapid geode]

but it was fine

[tardy badger]

I live at like 4800ft in elevation or like 1460m or so above sea level

Zone 6b

[rapid geode]

im in zoooooone... 6? canada/us have different zones. issue we have here it it will be very warm in march, things will bloom, and then we get a snow storm april 10th.

[night crescent]

SHOW and TELL 5/8/2024 https://youtu.be/wCNIPqw22RE

Ontario ranges anywhere from 0b to 7a

[night crescent]

ASK AN ENGINEER 5/8/2024 LIVE! https://youtu.be/fQEQZ6lpdhA

[rapid geode]

they are often 1 zone off. so us system says im zone 6. canada says 7

not tooo big a deal

[tardy badger]

There is negligible difference between 6b/7a

[rapid geode]

for most things yeah its of no concequence

[tardy badger]

Maybe a two weeks difference in growing season

[teal ginkgo]

im just tierd of all the phones out there and choosing a new one is hard so i got the idea of why not build one i mean i built a pc why not a phone so i need to get a rasberry pi with android and what more do i need can someone help me pick out parts and whats the cost of it screen battery 4g (or even 5 ifg it exists) module and camra i wannas know what i need

[rapid geode]

screens are spendy. $100ish with gorilla glass form waveshare with a pi interface

that would be something akin to a galaxy s5 oled

your phone would likely end up very fat

So... I feel like collectively as a society we've moved away from the light that is the Chevy El Camino.

[tardy badger]

It’s ugly, can’t hold more than 8 bags of dirt which a bike can also do, costs a lot of money..

[glad ruin]

You and everyone else with at least two functioning brain cells that aren't fighting for third place.

[burnt tendon]

There's a guy in the local area reddit who caught somebody's vintage DeLorean next to somebody else's Cybertruck on the street and it really makes it clear how you can apply roughly the same design principles and get two very different results.

[glad ruin]

... and when you buy it you are contractually bound to not be able to sell it to anyone other than Tesla.

[tardy badger]

I’d sell it to a volcano

[glad ruin]

I'd be afraid of polluting it.

[burnt tendon]

But, yah, the problem is that the best engineering solution is arguably the smallest lightest possible motorized vehicle say an e-bike because 60% or so of all trips are 5 miles or less and the total amount of energy required to make the e-bike work is a lot less and it doesn't need to badly replace your usual pair of a vintage DeLorean and Chevy El Camino for fun drives and hauling stuff.

(okay, so the DeLorean only looked cool and drove like a pig)

I kind of want one of those little Japanese trucks for going to the Home Depot

Last I checked, ~$8k to bring one in, license, and insure it

[violet parcel]

So Im reading xkcd what if and it seems far fetched that a fan rotating at 0.1c or a baseball going at relativistic speed can be so bad

I mean billions of electrons every second bombard earth at near 0.95c and a baseball isn't that much heavy just like if particles keep hitting the same spot it simulate a bigger object as in if I throw a baseball at a soft metal target it will make an imprint just like if I keep throwing pebbles over and over in the same imprint

[burnt tendon]

You know, I have an even worse idea: Import one of the Japanese kei trucks and then turn it into a Baja-style racing trophy truck.

[violet parcel]

So I dont understand why xkcd claims it would raze forest on a whole continent. Seems like a sci-fi story rather than science

[glad ruin]

I don't have my copy here, but I would refer to to the disclaimer at the beginning of the book.

[violet parcel]

does the book really have more content than the online strips ? I was under the impression that it's basically 1:1 for convenience

I'd have to look again, but I believe it has some content that isn't on the website.

[tardy badger]

Wow neat

I’ve only met a very small number of interesting people. Like Jimmy Wilks (former New Orlean Saints FB player), a country artist back when I listened to country, and.. I think that’s it

[burnt tendon]

I mean I've met some interesting people that I'd rather have not.

Randall is at least Randall tho.

[thick wind]

Which hurts more: the supposed bombardment of electrons at 0.95c, or being hit in the head by a baseball flying at 300 m/s (or 671mph, or 0.000001c)

Baseballs may not be considered heavy by our standards, but compared to an electron?

Probably not a fair comparison.

[violet parcel]

I honestly don't know considering some particles can causes mutations in cells similar to being irradiated

when a particle collide with a particle in a body cell

[tardy badger]

It’s kind of interesting thinking about this concept. In the 3 Body Problem books there’s a super computer AI contained within a proton that can travel at light speed anywhere on earth. But the fundamental physics of a proton would not allow that to happen outside of a vacuum

[patent hemlock]

the baseball -- you wouldn't feel the light-speed stuff

[tardy badger]

Science fiction is interesting though

[violet parcel]

There is also the hard to grasp concept that particles in my body are distant from each other yet I am a solid object. And according to QM Im a huge cloud of a statistics for the position and momentum of particles. So I alledgedly see my hand this way because my eye don't have enough resolution to show the empty space so what I see is a "blob" of probability as my hand it just so happened my eye cant discern little differences in the shape of my hand

[patent hemlock]

well, maybe yes, maybe no

[violet parcel]

so maybe it's not good if a stream of electrons going really space gets between some empty space in my body at some point ?

[patent hemlock]

that's just plain statistics because nothing is lined up in such a way as to create a straight-line empty-space tunnel

probably 😀

[violet parcel]

I still dont understand to this day half of what I was told about physics in university

all I know is that I can observe quantum superposition/shrodinger every time I sleep from my frame of reference. Until I wake up I'm in two states until I observe (quantum decoherence) that I survived my sleep by waking up 🤣

For the above I mean I was told about heinsenberg principle and the statistical nature of observing particles but no detailed explanation

And that QM is for phenemona at the atomic scale, something else is for macro scale and we cant unite the two

[patent hemlock]

i was a physics major in my university days, so i got a brief acquaintance with schrodenger functions -- tried to read the notes about 15 years later and it was gibberish

[tardy badger]

It was.. minionese

Didn’t see the tiny text at the top of that gif

https://tenor.com/view/minion-banana-gif-minion-minions-gif-81650879192259967

[violet parcel]

Apparently the correct words for my bed example is collapse of my wave function... or something

I was explained quantum entanglement with the shoebox thing so can you really blame me for finding such examples to understand ? 😦

The shoebox explanation goes something like Given a perfect factory that never get their shoeboxes wrong. You buy a pair of shoes when you leave earth and one fall off and you don't notice. You travel for years at light speed. Several years later you decide to open your shoebox and notice you only have the right foot. Since the shoes are entangled to each other we can say with 100% certainty the other one on earth is the left foot and this is instantaneous no matter the distance between the two

[patent hemlock]

oooh - i like that one!

[violet parcel]

It is to explain the part that is hard to understand that it happens no matter the distance without communication

[burnt tendon]

I thought only crypto techbros used phrases like "collapse the wave function" while describing the latest version of their fraud scheme to their confederates who turncoated to the feds the second they had a chance.

Oops. was that too sarcastic?

[patent hemlock]

nope

[violet parcel]

I dont even know what it means I just assumed a lack of humor when I mentionned my srodinger/quantum superposition sleep and someone said that

[patent hemlock]

iirc, "collapsing" just meant probability is approaching 1

and i'm too lazy to look it up

Hello! I would like to get into some (hobby) robotics stuff. Any suggestions (books, websites, hardware) that could help me get started? I am very much not mechanically skilled, but I would like to play around with writing "software that moves", whatever that could mean :)

[patent hemlock]

https://learn.adafruit.com/category/robotics

[patent hemlock]

i doubt there's any public documentation available since it's a closed platform

I forgot adafruit had a learning system X_X

I've never used one, but a few companies make prebuilt robot chassis.

Pololu might be a good place to start.

Not sure if adafruit still sells prebuilt robotics platforms or not.

[patent hemlock]

i also do stuff in Kotlin along the "stuff that moves and makes pretty graphics on small screens" categories

Speaking of, I am curious how you ended up landing on the idea of your robots running Java

I mean, I guess it is true that "millions of3 billion devices run java" ;>

Anyone here work with Altium Designer ?
I'm working on this circuit to transfer it to PCB, but one small component is missing: the 7-segment display. Its description is HDSP_A213. I couldn't find its symbol on the website or anywhere else. Can anyone help me ? 😀

[ebon dew]

Do you mean the footprint or the part from a supplier? Looks like it's made by Broadcom/Avago and is a 2.13V 7-segment display. You'll need a step down converter if you plan on using it with 3.3V. (2.5V is its maximum forward voltage).

[silver shale]

Likely would have to draw the symbol for it

[ebon dew]

Here's the datasheet. You can figure out the hardware pin routing and footprint from it. https://www.mouser.com/datasheet/2/678/AV02_2555EN_2022_12_16-1828003.pdf

[silver shale]

Where is the bit1630 sourced for this? I just need the IC https://www.adafruit.com/product/913

[ebon dew]

It's a Jinwang JW035PD01. The datasheet is included in the product page.

[silver shale]

Not the display itself, the composite video decoder IC on the board

[tardy badger]

It’s an led 7 segment display, you can run with 3.3V because you would need a current limiting resistor to not burn it up

Even using a 2.2V supply, unless it limits the current to Imax (max current) which it won’t always use, you will still have run away current

LEDs are current sinks and will sink as much current as is available until they blow if no resistor is in series

[ebon dew]

Does this look closer? https://www.bitek.com.tw/product_1221066.html

[silver shale]

That's the chip though there seems to be no source for it. The bit1612 seems to be available on eBay from a third party.

[ebon dew]

The TI ADS821 seems like it might be an acceptable substitute. Yeah no idea where they got them. Adafruit has ways to get stuff that mere mortals cannot because they buy in bulk.

[silver shale]

Makes sense they would get chips directly from the vendor at this point

Unless the PCB is from a third party

So, I've been an AdaBox subscriber for years and have tons of random bits. My daughter just found this in her room and asked for different games but I have no idea what it is. Anybody recognise it?

Seems to be a Digi-Key board but I would have gotten it via Adafruit.

Hmm. Maybe a PyGamer now that I look a bit more.

[tardy badger]

Technically speaking, Adafruit doesn’t sell on Amazon so your mileage will vary on if they’re true Adafruit units or not

[supple ice]

when will circuitpython for yukon come out

i want to run it on 3s

[fair summit]

do you mean pimoroni yukon? I don't know what you mean by "3s".

Pimoroni or a community member would work on a port

[glad ruin]

They have a type C version
https://www.adafruit.com/product/5212

But yeah, I agree. Sometimes type A is still the best.

[supple ice]

yeah and I'm referring to a 3s lipo

like three cell

[indigo furnace]

That's way too big comparatively. I use those for my phone, but these I mostly use for cyberdeck type stuff where it needs to be super low pro, cause the machine is often getting deployed in a truck or car.

Anything sticking out at or close to surface level is no good.

The problem is, these ones are great, but they break. So I have to keep cycling them

These weren't adafruit branded. Adafruit was just where I found them.

i think it also peaked around 01:00Z, too close to sunset for eastern North America

https://www.swpc.noaa.gov/products/aurora-30-minute-forecast it’s a bit tricky to interpret though

Many people that live near me have great views, but where I am it is super cloudy

[lusty fossil]

Hoping somebody has Automotive experience. I purchased this alternator pulley because it's a Freewheel belt pulley and I wanted to use it for a project. It arrived in the mail intact and in original packaging, but it is extremely stiff. To the point where I can't rotate it with my hands alone. I am wondering if there is a need to open it up and pack it with grease. There doesn't seem to be an obvious way to open it and I can't find anything from googleing the topic so I'm a little confused as to why it's so difficult to turn. Is that a feature and not a bug?

[whole jacinth]

it seems likely that lubricants intended for engine compartment use will be quite viscous at room temperature

[lusty fossil]

Darn, so it simply needs to be spun up. Unfortunately it will be used at a very low RPM. I wonder if I could open it up clean it out and put in different Grease

[whole jacinth]

it depends on the construction method. i would be somewhat surprised if it could be non-destructively disassembled

[fair summit]

i'm confused - wouldn't you want the alternator pulley to couple motion to turn the alternator shaft? If it turned freely it would not couple rotary motion to the alternator shaft. It sounds like it is some kind of clutch pulley

[lusty fossil]

You are right, except it's being hand cranked I need it to continue spinning once cranking stops.

It's on the output, the input is a normally coupled pulley with a hand crank, belt connecting them

[whole jacinth]

it seems small for an alternator drive pulley. could be an idler/tensioner?

[fair summit]

That is what I see here, for instance: https://www.oreillyauto.com/shop/b/alternators---starters/alternator-pulley/72378de79a3f

Alternator Clutch Pulley; Overrunning;

This Murray brand OAP is manufactured by the OE manufacturer. This replacement pulley is exact in all form, fit, and performance characteristics as the original equipment part (with the exception of not having the car manufacturer's logo or part number applied to the part). Under rapid engine deceleration, the pulley disengages the alternator from the belt drive system, allowing the alternator to freewheel, re-engaging when the RPM increases. The OAP alternator pulley ensures smooth, quiet performance. The OAP is designed as a sacrificial part of the front-end accessory drive system, protecting other belt driven component. Under normal driving conditions, the original pulley will require replacement in approximately 70000 - 90000 miles.

[lusty fossil]

Yeah these are basically all the same idea

Hmm seems like it needs high rpm

[fair summit]

maybe a bicycle freewheel would be better, if what you want is a ratcheting mechanism

[lusty fossil]

Yeah I was looking at that before but I liked the idea of a belt because they are lighter and lower maintenance

[whole jacinth]

huh, interesting. i hadn’t heard of that before

[lusty fossil]

I guess chain is the only way. Oh well.

[fair summit]

i looked for belt-drive freewheels. I did find some very expensive belt-drive bicycle parts. I don't know hthe mech-e names for a freewheel thing in general.

"ratcheting pulley" did not help

[rapid geode]

it may just need a break in. grease, cosmoline etc could be gumming up the seals, but after a few mins running it will smooth out. this is pretty common

[fair summit]

the torque on these is a lot higher than on some hand or foot-cranked thing

[rapid geode]

doubt it. a bike freehub has to take like 200-300 ft lb of torque

more than most small car engines

[fair summit]

i see what you mean. but the bike freewheel is designed to be really low friction, and it sounds like the alternator clutch pulley freewheeling is rarer

[rapid geode]

that is most likely going to be a sprague clutch

they dont get used in bikes cause they are prone to slipping at low speeds and high torques. but they are used a lot in one way systems in vehicles.

[fair summit]

thanks for your expertise. iwas going to suggest asking a mechanic or some car person at work but that is you. I did find a number of people complaining that they bought a rebuilt alternator and the pulley did not turn freely

[rapid geode]

anything with water tight contact seals will never spin freely

its not supposed to

but its all relative. 1nm in your fingers relative to 100's on the vehicle is "nothing".

[fair summit]

@lusty fossil more dicussion going on here

[rapid geode]

now if its crunchy and binding or just plain locked up, thats different

[lusty fossil]

I saw, I think the answer is to use a standard v-belt pulley that has a set screw or two and put a sprag clutch in the pulley bore and then Mount this Brad clutch on the output

Those pulleys are extremely cheap fortunately

[rapid geode]

and now... cats

😛

haha

[fair summit]

so when im carrying around my little rp2040 chippy thing to use at gaming meetups etc, how careful do i need to be with it? can i just grab it with my hands or should i wrap it up in something?

[strange sonnet]

I've always wanted to try embedding something like that in resin

[tardy badger]

generally speaking it is good to use some kind of ESD bag or foam, even having it attached to a mini breadboard is a good idea. But from practical experience, so long as you are not in an area that experiences a lot of static electricity (i.e.: no carpet) you’re generally okay to grab it

[ebon dew]

fair point. i never had any trouble with mine. i loved the bus powered 750 ti, it was great, low power, and low TDP (because Florida is hot enough already).

some of the cards from that generation would get my room up to like 110F in summer. was literally sweating using the PC. had to go low TDP after that.

are the LEDs you use from JLCPCB own warehouse, JPCPCB.com/parts? if so, I can think of no good reason why the boards need to be baked...
Of course, if you tried to solder LEDs that you found scattered without bag on a the floor of abandoned house in the middle of Amazon jungle, I would recommend baking them before use

Replaced the tiny 0603 sized fuse on the swing my wife found and now it works. Winning

[dusty citrus]

Is there any reason on why ic packages are so big compared to the actual ic?
Outside of being more manageable?

[rapid geode]

swing? like a motorised kids swing?

hehe

[rapid geode]

you need pins you can solder.

thats why you need SOC things to get really small where almost everything is shoved in one die/package

[whole jacinth]

at the extreme end we’re starting to see stuff like https://en.m.wikipedia.org/wiki/Chip-scale_package

Yup, a baby swing

[whole jacinth]

do you mean this? https://learn.adafruit.com/how-to-set-up-2-factor-authentication-on-adafruit/pi-2fa-f-a-q
or did you get locked out and need help getting unlocked?

[slim shard]

I'm curious what yubikey-like things can be faked with your average usb microcontroller device. Granting that they are usually readable, thus not excellent for security.

[late fulcrum]

AdaFruit offers things like the ATECC608 and Infineon Trust M on breakout boards if you want to protect secrets, and there are open source kits like the U2F Zero, which uses the earlier ATECC508. https://u2fzero.com/

[whole jacinth]

many Yubikey models have cryptographic smart card functionality, with optionally non-readable keys. and what madbodger said about the ATECC modules. (i haven’t tried them out yet)

can the soundFX board support State machine from the arudino? like it will continue playing one sound and if one switch is off it plays the current sound?

need to speed it up....

:x

[tardy badger]

And done

[stoic mesa]

you are placing components manually, using tweezers?

[tardy badger]

These ones I did, yeah

Not too bad for these boards

On IcyBlue, I place with my pixel pump because it’s like 400 components

[stoic mesa]

ever thought of getting a cheap PnP? like Opulo?

[tardy badger]

I’ve considered it

[stoic mesa]

of course, even a cheap one is a couple of thousand

[tardy badger]

I’ve been considering a YY1 from neoden

The Lumen PnP would also be fun

[blissful roost]

You're here... and you're NOT going to DIY?!?

Disappoint

[rapid geode]

ive seen lots of used pick and place machines lately. i have no idea if they are usable to a hobby person though. they seem like the type meant to do 500000000 boards a minute

[tardy badger]

I wish I had the need for such a machine

[rapid geode]

my peach tree has several hundred tiny peaches. wheee

[karmic walrus]

[blissful roost]

I have masses of this Rosey garlic around... ☺️

[rapid geode]

nice

im hoping to get at least 50 peaches this year. last year was 12.

[blissful roost]

Nice!

[rapid geode]

but the tree got so big this year

maybe it can set more than 50

the trunk is over 2" diam now

[blissful roost]

I've got a single, yellow poppy here.. so I have to make sure I get seeds from that!

At least it's not hot yet

[stoic mesa]

Unexpected Maker has some professional PnP machines, but then, he is doing tens of thousands of boards

[tardy badger]

Yeah, he has a maker goals setup

I aspire to that level

I need to sell a lot more than I do now to get there

Something on the order of 30-50 boards a day

If I worked at it, I could probably keep up with 20-25 boards a day. Maybe more if I had everything perfectly laid out

[rapid geode]

if i could sell 1 little guitar a day id be jumping for jhoy

haha

[tardy badger]

If I consistently got one order a day, I’d be happy

[rapid geode]

thats my threshold for it being a "business"

[tardy badger]

I got 3 orders on Tuesday

[rapid geode]

nice

[tardy badger]

But no orders since

[rapid geode]

i sold 2 cad files today

[tardy badger]

I sell fairly niche items though, in a market pretty dominated by more proven companies like tinyvision.ai, 1bitsquared, etc..

[rapid geode]

ah

[tardy badger]

So I’m trying to sell stuff that is a little different

[rapid geode]

i dont know how to sell (especially presell) anything. i can go "heres my thing, buy it" but that doesnt really work. the cad files didnt do anythign for months and months, and now has just become a steady 100/m but its all the old files. when i post new stuff, its again months before it gets take up

thats etsy with "no effort".

but i really dont know how to ramp it up. people respond badly to being sold anything

[tardy badger]

I put in a little effort on selling but I’m competing with my good paying day job for time so 🤷‍♂️

[rapid geode]

ah yeah

[tardy badger]

I basically get evenings in between giving my kids attention and then Friday afternoons through Sunday evening

Ordered these boards from JLCPCB today

[stoic mesa]

where do you post sell them? etsy? tindie? your own store?

[rapid geode]

etsy

for guitar cad

same with the keycaps. i posted them. everyone loved them, said they wanted them.... annnnnd nothing

:x

well not nothing. but not many sold

[stoic mesa]

yeah, to be successful, you need to spend a lot of time promoting your products, usually through twitter, build a following, etc

it is a full time job

[rapid geode]

basically, i need people to look for them. vs trying to slide it in front of their face

[stoic mesa]

my most successful product sold about 100 kits over the last two years. Which gives about one order a week 🙂
But then, it is $100+ kit

[rapid geode]

thats easier with guitars than with something frivolous like a keycap for sure

i sold 100 makerbot parts in one go. preorder style. BUT... i had a friend set that up. he said "i want this, ill put it out and get the orders, you make"

of course now that market is not viable

the same part is not 17 on amazon

:/

hehe

i guess its sorta an achievement that my thing was copied and now on every printer?

but i dont get no royalites, hahahaha

[stoic mesa]

🙂

[rapid geode]

i want one cent off every printer. ha. that would actually be pretty good money now

[stoic mesa]

what's the part?

[rapid geode]

i did the first metal extruder

[stoic mesa]

wow

[rapid geode]

but very quickly, almost instantly 10 other people jumped on and within a year there were much cheaper ones. that market evolves faster than you can make anythying

so im glad i made 10k and ran

haha

vs attempting to make some sort of business

i cant even find a picture of it anymore ha

[burnt tendon]

Yeah, "May you make a popular maker-ish product that people want" is almost a curse.

[rapid geode]

ha

at least with guitars there isnt the same downward pressure on prices. you just need to price according to percieved value.

[burnt tendon]

Like, some of my cosplay-oriented electronics bits if I refined them further would potentially actually be marketable? Except that the idea of actually going to the post office with finished and packaged products to send out is more than enough to deter me. I'd be that guy who has all of the bits in my geekroom ready to be shipped and can't quite get around to mailing any of them.

[rapid geode]

ha

the post office part is a big deal

packing my keycaps cost as much as making them

cad files are 0 work after you make them which is nice

but i cant seem to get that up from $3-5 a day to $100 a day

100 a day on cad files would would mean all my bills are paid which would be very nice to have

[tranquil swallow]

One thing I've noticed with new guitars is none of them on the entry level have rosewood fretboards

[rapid geode]

rosewood was blanket restricted a couple years ago. so nothing really comes with it now cause you need $100 permits to import/export

[stoic mesa]

but if someone copies your files and posts them online, you are busted...
with hardware, pirating is not as easy

my biggest problem - other than that I really do not want to spend any time on marketing - is support

I sell a kit, which is DIY thing - buyer is expected to solder and assemble it.

One in 10 messes things up and writes to me "nothing works". Try troubleshooting a complicated design over email...

[rapid geode]

piracy is complicated for things like this. im not really sure if it affect me in any significant way

id also say 90% of my customers have no idea what they are doing. 20% dont even read the description correctly. and a few even thought they bough real physical guitar parts (for $10)

sooo

thats why im not really pushing my NES game pad pi case hard either. i need 20 people and honestly, im still not sure it will be worth the effort.

[stoic mesa]

I am more lucky, almost all of my customers are very friendly and eager to build things, and more or less understand what they need to do. But not all of them have the skill to do it right on the first try

[rapid geode]

yeah

i get "how do i put this file on my cnc

um... theres a few steps there :x

[tardy badger]

I built up 5 IcyBlue, but funny thing. My pixel pump’s foot peddle wasn’t working so I had to tweeze the entire board lol

[dusk flax]

I keep seeing you talk about these. What's something different one could do with this feather, vs say a RP2040 or M4?

[tardy badger]

Well, it’s an FPGA feather so you can do whatever you can describe on it

[ebon dew]

If you could figure out a way to make these into displayio accelerators they would fly off the shelf. No idea if that's possible but I would totally buy a lot of them if you make that a thing. I wouldn't even know what to do with a bare FPGA.

[rapid geode]

for my next trick....

[tardy badger]

Maybe not this one, but I have another fpga feather that’s designed specifically for high speed video

[oak abyss]

can you put ferrules on mains powerlines then screw them into the wallsocket or is this bad ?

they look more neat and each copper wire within wont curle

[celest latch]

I am working on a project to develop smart glasses for blind people using the following components: ESP32-CAM, ESP32, FTDI, Speaker, and an Arduino Uno (if necessary for power supply, providing +5V to the ESP32-CAM, +3.3V to the ESP32, and GND). The objective is divided into four steps:

Programming the ESP32-CAM: The first step is to program the ESP32-CAM to help the blind person detect different object classes using a YOLO (You Only Look Once) model.

Integrating ESP32-CAM with ESP32: The second step is to integrate and program the ESP32-CAM with the ESP32 microcontroller.

Digital to Analog Conversion: The third step is to convert the digital information processed by the ESP32 into analog signals. This will involve converting detected object class names (text) into audio signals.

Audio Output: The final step is to output the audio signals through a speaker, allowing the blind person to hear the detected object class names.

Can you help on this project ? is any component is missing to work on this project ? or there a better method to do this work ?
thanks with advance 😀 (or with Raysbery pi , i have it also)

[late fulcrum]

Sounds like what Ximira is building https://www.ximira.org/. I would expect the Pi would be more appropriate than the ESP32 for running an image recognition model (something like a Jetson might work well too). The audio side isn't too complicated.

[patent hemlock]

yes, this is bad -- if you screw with mains wiring and use non-standard components, insurance agents will laugh at you when the house burns down

Or Digi-Key/Mouser like it lists for distributors?

[celest latch]

My project need necessary ESP32 CAM , the détection its working do you have any idea about how to convert this objects detected to sound

i cant buy them from others sites, do you have any idea of how can i find them?

[tardy badger]

They’re probably not going to be available

oh ok ty

[late fulcrum]

It depends on how complex you need your sound to be. If you just need a few clips, something like https://www.adafruit.com/product/2342 might work. If you need something more nuanced, you might need some sort of speech synthesis.

[stoic mesa]

please do not cross-post the same question in multiple channels

[blissful roost]

Hummmm... Anyone care to guess if an old fish tank panel will be flat enough for lapping heatsinks?

I'm leaning towards doubt.

[patent hemlock]

i doubt the glass is smooth enough -- those are built more for transparency and strength - plus they might be laminate, which i think would be not good

[blissful roost]

I don't think it's laminate, but... Not the expert.
I was thinking as you've said, for strength.

Dang.

[patent hemlock]

it doesn't hurt to try -- if it's not smooth enough, you'll just need to get something smoother, and if it is, you're done, right?

[blissful roost]

I certainly don't have anything to test that, at least not to a good enough degree.

I could just test it with an .. Oohh! Stock Ryzen heatsink!

I was going to cough donate it.... 😅

[patent hemlock]

dude - those things are rock solid!

while i was building my computers, i hardly ever strayed from the stock heatsink/fan that came with the ryzen

[blissful roost]

I think there was one good model, the other two were trash... ?

[patent hemlock]

i only had a sample of 5 across ryzen 3 and 5, so i have no other data

[blissful roost]

I have the stock cooler for the 3600.. it ain't good. 🤣

I got the Hyper 212 instead.

I really don't like "silent" coolers in my gaming rigs. ☺️

[rapid geode]

Sure why not? it just needs to be nice and flat. strength is not required. (note, the glass will also lap flat as you go). the only glass that is a big nono is tempered, cause you could cause it to expoled as the grit grinds into it

i will say, most people do not understand what lapping is, and wind up just sanding the part

[strange sonnet]

I always assumed it was whatever lapidaries did

[rapid geode]

yes, that is lapping

the key thing is that BOTH surfaces are ground together in a randomised fashion. this is how they become flat, as opposed to one just forming to the surface of the other.

i wont get into the idea of lapping the cpus etc, thats a who different land of misunderstanding 😛

[late fulcrum]

Or mirror grinding?

[blissful roost]

Ahh, yes! I wasn't thinking about that.
Me am brain dumbed sometimes.

[rapid geode]

🙂

hehe

mine is mostly dumbed

hehe

[strange sonnet]

I wonder if lapping is etymologically related to knapping

[rapid geode]

no

[patent hemlock]

interesting, since they both involve removal and shaping, but i can't find any indication they share etymology
@blissful roost you could always cut off a piece (or use another from the same tank) and carefully break it to see if it's tempered or not

[blissful roost]

That was left behind by a previous occupant, so it's the only piece I have.

I have no intention of trying to cut or break it in any way.... I have a bad history with glass. 😅

[late fulcrum]

For flatness, a mirror is useful.

[fast ferry]

true! they use float glass for mirrors. very flat.

[late fulcrum]

Cool, I didn't know that. I knew they were flat, but I didn't know how they got that way. But thanks to "How It's Made", I know what float glass is!

[patent hemlock]

oh! i totally forgot about that episode (we binged the whole series so it's a bit of a blur)

[rapid geode]

almost all glass if float glass. but mirrors are especially flat. dont want no fun house wobbling.

i use a granite plate for this. but they are heavy and slightly expensive

"this" being lapping machine parts, not cpus.

[tardy badger]

I like state machines because they seem like too much fuss to implement for simple state management at the start of the project, yet they also look like too much work to graft on once you figure out you really need one in the mid-to-late stage of your project

so I've been reaching for them earlier and earlier, heh
