[solar furnace]

Lol

[tardy badger]

I’m actually not 100% sure what I’ll be either

[solar furnace]

I mean that's just an apron, a dress shirt, jeans, and a chainsaw

Ofc the mask but I don't really wanna spend 30 dollars

[tardy badger]

Part of me wants to be my favorite anime character, Luffy

[solar furnace]

And my school doesn't allow masks

Ooo

That'd probably be pretty affordable too

[tardy badger]

Yeah

[pallid orbit]

I got my first tech helmet prototype working in time for a costume party last weekend, and called myself 'The Construct'

[tardy badger]

Oh nice

[pallid orbit]

it still needs a lot more work for what I'm aiming to do with it though, but it was a neat first run. eyes kept crashing though 😆

[tardy badger]

I want to get a bigger, multicolor capable 3D printer to print myself some various suits

Like a gundam suit

[pallid orbit]

I'm awful at 3d modeling so I had been poking around at existing prints online, even paid ones, just to get an idea of a base model I could try editing in blender

[solar furnace]

I wish I had a 3d printer

Would make prototyping synths slot easier

[tardy badger]

I have an Ender 3 that’s pretty good for what I currently use it for

[pallid orbit]

I got an ender 3 I got for $100 at microcenter in one of their super cheap printer sales

[tardy badger]

But I’d like a set of higher end printers to make suits

[solar furnace]

Oh wait 3d printers are affordable now?!

[pallid orbit]

I end up with a failed print every few prints because of bed level calibration or adhesion issues, kind of annoying

haha yeah

[solar furnace]

Like 8 years ago my cousin saved up a whole summer for a small one lol

[tardy badger]

I love the idea of making a wearable, electronics filled Gundam suit

[pallid orbit]

the more expensive ones are fancier and can do multiple filament colors in one print, auto-level and can print faster too

[tardy badger]

You can still spend $1500+ on a good printer

[solar furnace]

That'd be a very interesting project

Creating a modular costume maybe

[pallid orbit]

not gundam persay but basically what I'm doing. I ordered a stereopi slim board and some cameras so I can implement passthrough into my helmet (since atm I cannot see out of it really)

[solar furnace]

Sight isn't important, compared to drip

[tardy badger]

Oh yeah, I plan on doing that do

But more of a VR kind of headset

You can get the HD micro led displays on Aliexpress for like $60

Or buy the actual ones for like $300

[pallid orbit]

yeah, I took apart a pair of Rokid Air which is a 1080p 'AR' wearable display using birdbath optics, and put it into my helmet. I have a wearable PC already operating and it runs video to the glasses hardware

[tardy badger]

https://www.displaymodule.com/collections/micro-oled

[pallid orbit]

before like 4 months ago I'd never soldered before, so building my own electronics seemed totally out of reach. past 2 months I've done like 600 solder joints haha

[tardy badger]

Nice!

I’m targeting something like this: https://www.displaymodule.com/products/0-39-inch-micro-oled-display-1920x1080-with-mipi-i2c

[pallid orbit]

yeah turns out soldering 90x WS2812B lights together in 18 strands with 4 inches of wire between each one and coming up with power rails to connect them all + other connections and practice is a nice experience grind

[solar furnace]

I still haven't soldered

[tardy badger]

I’m planning to make a board using a Lattice Semi Crosslink-NX FPGA to handle video processing and MIPI interface

[solar furnace]

All I do is research parts and study designs atp

[tardy badger]

Well, we all start where we’re comfortable

[pallid orbit]

that's from taking apart the rokid air AR glasses and putting the main display portion into my mask/helmet

don't have to worry about the display, driver, lining up the spacing or optics since this already 'solved' all of that, plus it has an IMU in it that I can read from on my host machine that is directly USB-C connected to it

would be cool to implement more specific hardware on my own once I get more experience

luckily since I've started working with microcontrollers and soldering stuff this year, the only thing I've managed to damage/break was a single microcontroller

[tardy badger]

Nice work

The thing to understand about winter holidays, cross-culturally, is that winter was once a very scary and frightening thing where you were forced to rely upon food stocks from better weather and the days were short. So it kinda makes sense that there's a lot of common threads between the various winter holidays.

Nightmare scenario

[solar furnace]

But why?

[glad ruin]

Marketing hype.

[solar furnace]

Amen

It would serve no purpose, and is would be likely not fun to use

[glad ruin]

... but it will be an investor magnet.

[solar furnace]

Investors, give me your money instead.

I'm also capable of coming up with random buzzword filled concepts

[glad ruin]

The entire concept is mind-numbingly stupid.

[fossil dawn]

Question is: Did they just let an LLM write that concept?

[glad ruin]

Speaking of which, it comes as a shock to me that the people with money to burn are also the ones who seem to fall for the marketing hype.

[solar furnace]

Not very surprising to me tbh

They pay people to be smart for them

[tardy badger]

ChatGPT is something I view more as a toy

Like, sure there are some things it can do decently well. But I wouldn’t bet my wallet on it

[solar furnace]

Yeah, trying to make actual money off it a is bad idea

[glad ruin]

The trouble is that actual money is being thrown at it

I find it interesting that humanity tends to immediately gravitate towards the most irresponsible use possible whenever a new technology emerges.

[solar furnace]

Humans aren't known for their foresight lol

[rapid geode]

pft. they predict the end of the world every day... one day they will be right. thats pretty impressive

[tardy badger]

Throw enough darts at a target, you’re bound to hit the center at least once 🙂

[old fjord]

Idk how to spend 3 hours at micro center

Go to the aisle to find something I want, they have all the options except the item I want, or the item I want is out of stock.

I think enthusiasts think alike in terms of buying technology and what is left over is too expensive for an impulse purchase, or too specific.

[lunar aurora]

Raspberry Pi 5 is ouuuuuttttt, so excited!

[solar furnace]

I don't know who makes the Adafruit tiktoks, but thank you so much for making soldering look alot less intimidating

[pallid orbit]

yeah soldering seems like alchemic magic until you 'get it'. I only just learned this year

still can't quite get desoldering to work with a copper wick though almost ever

[fickle aurora]

I’ve only had it help with pad cleanup, never through hole

[coarse nova]

Hey all, what's the proper name for the male end of a 4-pin PWM Fan connector? The kind that you connect to a cable, not the board header kind.
I've found kits of 10 for $10, or I could order them from HK with $10 shipping. Haven't seen them in mouser/digikey though.

[ebon dew]

4-pin JST SM? https://www.adafruit.com/product/578

[marble flax]

iPhone 15 Pro has some pretty good macro skills built-in. Shot of a HDMI connector.

[blissful roost]

Very not bad.

[fickle aurora]

What did you have to do to get that photo? My photos are never that clear with the same phone

[old fjord]

iPhone macro photos have actually gotten worse over the years as the sensors get larger.

This was shot on an iPhone 8 Plus

[coarse nova]

Similar, but not quite. It looks like it's 2.54mm pin spacing, but doesn't have the clasps on the sides. Also the male socket/header version has "keys" to ensure that a 3 or 4 pin female plug has the 1/2/3 wires in the same spot.

Here’s a photo of the two sides of the connectors from an extender cable.

I have found the female housing side though, it's a "Molex KK 254 Housing with Polarization Rib, 4 pin"
https://www.molex.com/en-us/products/part-detail/470541000

There's a motherboard header variety of the male side, "KK 254 Vertical Header, with Friction Lock, 4 Circuits", and the friction lock has the correct spacing for the polarization ribs, but I'm looking for a socket version of this.

Is there anything like the x0xb0x, but more affordable? Just a easy rewarding synth kit.

[teal berry]

https://www.adafruit.com/product/4383

how do we know if the displays can show video or are just for like jpegs

[marble flax]

That’s the function of “refresh rate” but generally TFT and LCD can show video it all depends on the microcomputer that you are using if it has enough ram or GPU.

E-INK displays for example have a refresh rate of multiple seconds, so you can imagine you won’t be able to play video on those

[teal berry]

do you know of a good tiny display with video off of the top of your head?

ok so the only think on the display that matters is the refresh rate.. and then the microcontroller is what determines how well the video plays?

[late fulcrum]

Whereas the macro photos on my DSLR are excellent, even with a much larger sensor.

[teal berry]

broooooooo OOOOO 😂

wait so this does video too?

well, if the board is good enough?

what kind of connector or rasberry pi is needed for this?

[late fulcrum]

Apparently it supports MIPI

[teal berry]

you gotta dumb this down to like 2nd grade level lol

I'm new to this

[late fulcrum]

This is a fancy industrial display, it's not aimed at the hobbyist market. You'd probably have to do a fair amount of hardware and software integration to use it, and it's not cheap.

are 1206 (3216 Metric) smds difficult to manage with tweasers? I have no frame of reference, though I have soldered many small components before, some are too small, But I haven't noted what size is too small, so, is 1206 (3216 Metric) considered big or small for a highly caffeinated individual?

[late fulcrum]

1206 aren't hard, if you've soldered small components before, I doubt they'd give you a hard time.

[glad ruin]

1206: easy
0804: intermediate
0603: difficult
0402: you will regret being born

[fierce prawn]

Apparently designing your own pcb isn't hard at all

[dry mantle]

I need a clarification in offsetting time in Circuitpython

i have a time stored in a variable in this format
struct_time(tm_year=2023, tm_mon=10, tm_mday=27, tm_hour=15, tm_min=57, tm_sec=10, tm_wday=4, tm_yday=300, tm_isdst=-1)
I need to offset this time by a certain seconds. How to do it.
I am using Circuitpython running in ESP32 S3

[rain cradle]

you can maybe crate anotherstruct_timemanually and add them together

on "regular" python i would use a timedelta but i guess it may not be compatible with the struct_time format

[dry mantle]

Thanks for the input

[jagged citrus]

Its not hard at all

Its quite easy really

But dont be like me, please double-triple check the layout, dimensions and size of your board before manufacturing

[umbral phoenix]

@dry mantle```py

import time

offset_seconds = 3600
time.localtime()
struct_time(tm_year=2023, tm_mon=10, tm_mday=27, tm_hour=8, tm_min=47, tm_sec=35, tm_wday=4, tm_yday=300, tm_isdst=-1)
time.localtime(time.mktime(time.localtime()) + offset_seconds)
struct_time(tm_year=2023, tm_mon=10, tm_mday=27, tm_hour=9, tm_min=47, tm_sec=45, tm_wday=4, tm_yday=300, tm_isdst=-1)

(usually easier to work in seconds, then convert when needed)

You ever wish AliExpress listings were more clear?

Both of these are USB C 328p nano's, but one is $0.20 cheaper than the other

[jagged citrus]

No

[fickle aurora]

Like a big flashing text saying Caveat Emptor?

[old fjord]

https://tenor.com/view/money-rich-gif-25596211

[tranquil swallow]

Yea I see that all the time with listings, in my experience there's no difference beyond price

If sorting were useful on alix I'd get the cheapest one

[fickle aurora]

What are the jagged edges you’ll see on some DIY PCBs related to? My guess is some process to cut the PCB from another one

[umbral phoenix]

castellated, or just rough from cutting the boards apart?

[thick wind]

Looks like one of them might be a 168p instead of 328p.

[ebon dew]

Castellated edges are for making solder on modules or as a way to attach pins to the side.

It has its advantages.

[jagged citrus]

For real

On god

[haughty solstice]

That'll do

[haughty solstice]

I zoomed in on the picture and if that's accurate it shouldn't be, but I went with the slightly more expensive one just because

Also why is the Uno so much more expensive compared to the Nano when it's the same IC

[jagged citrus]

Size

Extra components

[haughty solstice]

Ah

I'm trying to think of what else I need since shipping takes like a month and I can save $2 if I spend another $5

[jagged citrus]

+20 dollars if its a genuine made in italy

[thick wind]

A lot of it comes down to manufacturing costs. THT operations, extra connectors, and an additional power regulator...

[haughty solstice]

The branded Arduinos vs. the 3rd party ones are basically champagne vs. sparkling wine

[thick wind]

Genuine UNOs also use a more expensive 16u2 microcontroller for USB to serial, while the cheap clones prefer cheaper purpose-built chips like CH340 or CP2102.

[haughty solstice]

I really wish AliExpress had one of those metalic matrix keypads instead of the black plastic ones

Or something like this

[thick wind]

For those, you're better off looking for junk secondhand phones locally to dismantle haha

[jagged citrus]

Am i the only one that thinks using a full microcontroller as a USB to serial bridge is kind of a waste? Especially when this bridge mcu is more powerful than the main mcu (i believe the nano Every does this with the SAMD21 as the serial converter). Why not just use an FTDI or CH340

[haughty solstice]

Yea I'm just not sure where to find any. May have to stop into a local thrift store

[fickle aurora]

I think rough from cutting boards apart. I’ll get a pic soon.

[thick wind]

USB-UART chips were not widely available as they are now back when the UNO was first designed. The 16u2 hardware peripherals and memory are slightly inferior to the 328P, and in some niche cases the 16u2 itself can be reprogrammed to enumerate as a different class of USB device.

[burnt tendon]

I mean, it's important to understand that your computer, such as it is, is itself a stack of various microcontrollers (mostly ARM) that are all making a very hard effort to pretend that they are hardware. It's turtles going all of the way down.

[jagged citrus]

Ah, that makes sense

[haughty solstice]

Why is the 28BYJ-48 stepper motor always sold with a ULN2003 board? What does that board actually do?

[jagged citrus]

Drive the motor

Stepper motors require special driver boards to work

[burnt tendon]

And while there are plenty of fancy nice nifty stepper motor drivers, a ULN2003 is extremely cheap and simple by comparison

[jagged citrus]

I once bought an ADC board for the raspberry pi and instead got the motor driver

(Without the motor)

[haughty solstice]

I'm also trying to figure out why this kit I got years ago comes with both a ULN2003 board and a L293D motor driver IC

[thick wind]

Microcontroller GPIO are not rated for the currents typical of a stepper motor, so having the ULN2003 is a nice convenient alternative to a complicated H-bridge circuit.

[jagged citrus]

Maybe maybe

[thick wind]

L293D do similar things, but they're designed for traditional motors rather than steppers.

[haughty solstice]

Like a servo or something else?

[thick wind]

Servos don't actually need a driver IC; by definition the control curcuitry is already built into the servo itself.

They draw considerable current, but only on the power line. The data line is perfectly safe to be driven directly from a MCU GPIO pin.

[jagged citrus]

Generic dc motors

[thick wind]

L293D is a an H-driver for brushed DC motors.

Usually they're the cheapest driver for motors like https://www.adafruit.com/product/3777

[haughty solstice]

Can you tell when a stepper motor has been manually turned to some position to use it like a knob?

[jagged citrus]

Seems very complicated, the only thing similar that ive seen is someone turning a hard drive brushless dc motor into a rotary encoder (knob)

[haughty solstice]

Rotary encoder, that's the term I'm looking for

[jagged citrus]

https://m.youtube.com/watch?v=tjCJ3MlFt7g&pp=ygUOR3JlYXRzY290ciBoZGQ%3D

At that point i'd just buy a knob

Probably cost less than a dollar

Maybe you could use the large disk as a dj turntable

I believe the first is Microchip's own devboard for one of the AVR chips, and the other is a totally unrelated PoE module for what I think is an ESP32?

[jagged citrus]

Second one looks like a ethernet adapter of some kind

I discovered they come from the arduinodroid app

[late fulcrum]

I remember when Electronic Goldmine had some of the metal ones at a good price

[haughty solstice]

😔

[restive torrent]

That second one is a generic ethernet adapter breakout, I used a bunch of the previous version for some undergrad work

[urban arrow]

Hi all. General question. Do you know how to add a new board to Visual Studio Code that does not already appear in the Choose Board options? I have a couple of new S3 boards that do not show. If VSC doesn't know the board, u can't use Serial Monitor
Not a big problem, I just use MU in another window to view Serial Monitor. Thanks.

[proper umbra]

the usb just fell off the board, that was issue

[proper umbra]

USB-C but not USB3....

[fossil dawn]

USB 3 is backwards compatible. My USB-C Smartphone also is only USB 2.0

[proper umbra]

not the issue

[fossil dawn]

🤔

[proper umbra]

this board doesnt get recognized on usb3 ports

but it does on native usb2

[fossil dawn]

interesting. Did you post that in the adafruit forums? Afaik the forums are way better for that kind of official support and bug reporting. Because there are more official adafruit people than here

[proper umbra]

I searched, I will post

[old fjord]

I only have USB 3.0 ports. These dev boards work fine. I have a ESP32-S2 metro and I definitely used it with USB 3 ports.

[warm scarab]

Hello, I'm currently looking into how to load natively compiled code onto the PyBadge LC...is this a good place to discuss that?

[jagged citrus]

Its very strange, (USB type C on phone and boards) i can program my ESP32 S3, but if i connect a regular ESP32 with the same cable it doesn't detect anything, doesnt even get powered.

Also, not all USB C devices are USB 3.0 compatible

[warm scarab]

So far it looks like the bootloader for the pybadge lc (SAM51 I think) loads the "application" here: https://github.com/adafruit/uf2-samdx1/blob/master/src/main.c#L98
Based on a uf2 file I downloaded from makecode, it looks like you load your app at address 0x4000.

[warm scarab]

I think I was able to figure out what I need to do. Gonna start with a Hello World in assembly, anyone know of a good assembler for the Cortex-M4F?

[tardy badger]

Which cortex m4f are you targeting?

[warm scarab]

Not sure, I've got the PyBadge LC which uses ATSAMD51

Homeassistant

[cunning frost]

I've pretty much done something of that sort recently (migrating everything locally, using cloud service alternatives, self-hosting websites, setting up tunnels) mostly for fun and I don't know if it's a "must do" but it's certainly cool how flexible you can be with them. The only downside (or upside) is the redundancy rabbit hole you might find yourself in especially if you want high availability. That and upfront cost if you don't already have the hardware.

So many cheap options though if you aren't picky.

Dang, the new MacBook Pro can be configured with 128GB of RAM

[olive dome]

with 16 core CPU too

[umbral phoenix]

disappointed there's no 27" or larger iMac

[glad ruin]

How much do they charge for it, and is it ECC?

[tardy badger]

128GB is a $1000 upgrade

[tranquil swallow]

😿

[tardy badger]

fully spec'd 16" is $7,199

honestly not terrible

I kind of expected worse

[olive dome]

https://www.realworldtech.com/forum/?threadid=210314&curpostid=210314

On the M1 Ultra, Apple has 8 128-bit DRAM packages, which provides a total of 64 16-bit LPDDR5 channels. On a system with 64 GBytes of DRAM, a 128 byte cache line plus 4 bytes of ECC could be stored in 66 locations of one 16-bit LPDDR5 channel.

[glad ruin]

Ok, so I just bought 128GB of 3200MT/s DDR4 ECC UDIMMs for... $250.

[olive dome]

Inline-ECC

[tardy badger]

keep in mind that we're talking on die memory which will be more expensive than standalone memory.

so..

yeah.

[glad ruin]

Well that's better than nothing, and signal integrity is not as big of a concern since they are soldered to the board.

[olive dome]

Also LPDDR5 and not DDR4 that is being phase out

[glad ruin]

But that's still a ridiculous markup.

[tardy badger]

sure, definitely not for people like me

I can't justify $5.1k for a laptop with 128GB of RAM and 2TB of storage

[olive dome]

I bet there are people going to desolder the memory and upgrade it anyways

Memory chips pricing are not that bad

Did that with my CM4 before

[tardy badger]

If I upgrade my mid 2017 intel macbook pro, i'll probably just get a normal M3 MBP

considering I paid like $1800 in 2018 for it, and an M3 with 16GB of RAM and 512GB SSD is the same price retail.

I could get a whopping $300 for my current MBP

Lol

[olive dome]

Not bad for a 2017 MBP

[tardy badger]

Yeah, I’m surprised

[late fulcrum]

Having the stack visible is useful for learning how RPN really works

[burnt tendon]

Yeah, I have to say that I only really love RPN when the stack is visible. Otherwise the odds are just stacked against me.

In HS physics class, I had way too much fun solving a giant swath of the problems using vectors, which we hadn't actually been taught but I knew anyways because NERD, on my HP48gx with the lovely visible stack and RPN.

In HS chemistry, we were allowed to have calculators, and I had the good fortune to have an HP-55 programmable calculator. The teacher saw me blowing through problems, hitting the R/S key. He asked what that key did, and I explained that it was the Ideal Gas Law key. The next week, the test was for something else and I had written the appropriate program. He was confused when the R/S key again magically solved the problems, and he said he thought it was the Ideal Gas Law key...

[patent hemlock]

oh geez -- i was on the speed-rule team and had a Pickett 905-ES

[burnt tendon]

I was too much of a rule breaker for that.

[patent hemlock]

"stone knives and bearskins"

[burnt tendon]

It's OK, you don't need to have used a slide rule to yell at kids to get off your lawn these days.

[patent hemlock]

oh, i'm past that (plus no lawn) 😃

Hi could I get some help with something? I've been looking to setup a monitor on an RPi3B+ that auto-loads a locally saved video file on startup. I found something called Yodeck but it requires wifi or ethernet. Does anyone have any ideas as to what I can use here?

Happy Halloween everyone

[rapid geode]

happy pumpkin pie day

mmmm

[fossil dawn]

how is that made? First, machine the wood, then fill it with black plastic(?), then machine the esc and fill that?

[rapid geode]

yes

[fossil dawn]

sounds expensive 😆

[rapid geode]

https://www.youtube.com/watch?v=aqLXee705T4

ha. it is expensive

but no worse that the resin artisan keys

much classier though

[fossil dawn]

but I like the design! Not sure if it would be too much or absolutely amazing to have the line go all the way through esc, tab, caps, shift, ctr 🤔

[rapid geode]

i will never do cedar again though. ha. so many rejects from chipping etc

[fossil dawn]

wood is kinda underrated nowadays

[fossil dawn]

oh wow

[rapid geode]

theres about 60 "good' ones. and 27 that needs some fixing. theres some tiny voids in the blue text one some.

need to make some colour matching liquid epoxy and put it in with a pin. then sand. should be un noticable

thats of 130 total. the rest went into the bin due to bad chips and splits

oh well.

bloodwood is next, that one has very few rejects

didnt do the pizza one yet. only the other 3 (cause they are the same colours as the cedar)

these ones have a curved top

[fossil dawn]

oh wow that sounds even more expensive

[rapid geode]

yeah the cedar is bad. wont do it again.

stick with hard woods

haha

purpleheart has a few fails as well, but i have it mostly under control

[fossil dawn]

That pizza and cat eyes look super delicate

[rapid geode]

not really. the engraving goes really well. not a single failure yet there (except voids when pressing the epoxy in)

the pizza might be a problem cause of the peperoni "islands". but i think it will be fine

bloodwood doesnt chip much though. nice and stable

i havent plannbed out most of the other inlays yet except the ebony, which is the dead smiley

in yellow and red

[spice moss]

happy halloween

Random PCBA rep: “you website indicates you may need PCB/PCBA services”
Me, whose website is offline:

https://tenor.com/view/interesting-batman-very-interesting-thinking-gif-16421084

[rapid geode]

someone called me saying they saw i was looking online for real estate....

eerrrrr

looking through my window?

[tardy badger]

At the property across the street that’s 4x more than what you paid for your current abode?

Also at like 8% interest rates

Idk what canadas interest rates are at

[rapid geode]

6

my mortgage is 1.99%

[tardy badger]

The billboard on the drive home yesterday said 7.770% for me

[rapid geode]

not in any hurry to renew 😛

[tardy badger]

So I won’t be buying a house probably ever

[fossil dawn]

well yeah, you obviously need PCB/PCBA services to produce a new motherboard for your server to get your website back up 😆

[tardy badger]

Ah yes, thank you lol

I think about how if I wanted to produce my own mother board to handle like.. an Intel or AMD socketed processor, that it would probably cost me.. a few thousand dollars

[tardy badger]

But think of all the equity just sitting there

Lol

[rapid geode]

i want a pcb that fits inside a keycap that has its own rgb leds, batter and usbc charging port.

[tardy badger]

Could just do wireless charging

[rapid geode]

just for the sake of being completely idiotic 🙂

[tardy badger]

Or wireless power

[fossil dawn]

I saw someone on youtube make a "PC" inside a lego brick with a tiny screen and RP2040

[rapid geode]

i thin i saw that

[fossil dawn]

https://www.youtube.com/watch?v=6wBrOV2FJM8 one of their videos

[rapid geode]

wow

ha

[fossil dawn]

https://www.youtube.com/watch?v=SNJpRXlfKQE

[tardy badger]

Anyway, as for houses. Median house in the US is $410k, at current interest rates, and the suggested Debt-to-Income ratio of 36%, a person with 0 other debt would need to make over $120k to buy that

The median income in the US is $67k

[fossil dawn]

You could even just wire it to the keyboard for power

[rapid geode]

yeah. as its stands, on my salary i would not be approved for any available house (not even mine)

and im in the top uh, 5%?

its horrible

[tardy badger]

I make (with my current overtime) $114k but I unfortunately have student debt

[rapid geode]

it will all collapse soon

[tardy badger]

So the best I can afford currently is a cardboard box under a bridge or the $2300/m rental I live in

[rapid geode]

ha

yeah

rent is really bad right now. 3k+ for a 2 bedroom

[tardy badger]

I pay $2294 for a 3 Bed 2.5 Bath townhome

I see houses selling in my area (albeit slowly) and I sit here wondering what do these people do for work, and where are they getting the $350k+ down payment to make the mortgage reasonable

[rapid geode]

that would be 4-5k/m here

[tardy badger]

Ouch

Rental prices are apparently going up which drove inflation upwards last month

[rapid geode]

1700 for a no bedroom basement

yeesh

[tardy badger]

🥲

I’m basically stuck where I live currently for the foreseeable future

Even being a professional who makes $110k ish a year

[rapid geode]

my old 1 bedroom condo is renting for $2500+ now. oof

[tardy badger]

😵‍💫

[rapid geode]

i was paying 1800

im really glad i bought this house in the end. even if it is a problem child

haha

[tardy badger]

My wife is working on a computer science degree so that should help us qualify for a slightly larger rental in the future

Anyway, TLDR: being an adult is unnecessarily expensive these days

[rapid geode]

ha

i need to sell rich people keycaps

then i can be rich too

[tardy badger]

I might try to sell my little KeyBoy game thingy. Idk, not really sure

It’ll be a bit shorter than this

Not really sure people could afford it

[rapid geode]

thats the hard thing. its certainly not going to be $9.99

with the keycaps i just "dont care". they cost what they cost, and luckily there seems to be a sliver of people that will buy it.

[tardy badger]

Yeah, there’s like $11 in parts on it, probably closer to $15 with the speaker

[rapid geode]

electronics though it harder

[tardy badger]

I try to do a 2.5x multiple on parts cost to cover worked hours, and replenishment costs

[rapid geode]

ive also been finding that packaging up the thing costs more than the thing

[tardy badger]

So $37.50

Add in a 3D printed case, probably closer to $45

If I wanted to pay myself for time put into making games for it, probably $49-$55

[rapid geode]

i used to make $100 extruder arms for 3d printers. now those are $9 on amazon.

[tardy badger]

There’s still people who would pay $100 I bet

People who understand that cheap won’t always last as long

$100 once, vs $9 how ever many times plus the time to replace it when it breaks

[rapid geode]

no, i mean the same thing for $9. the difference between me making 100, and a big chinese comapny making 40000

[tardy badger]

Oh

Gotcha

[rapid geode]

back then makerbot selling 5000 machines was crazy. now creality does that in a day

stratasys really got their $400m worth on that deal, hah

[tardy badger]

I’d say

I personally just need $1m and I could do some cool stuff

[rapid geode]

(sarcasm, the got hosed)

[tardy badger]

Heck, even $250k and I could do some cool stuff

[rapid geode]

1m would get me a nice shop with all the cool toys

[tardy badger]

I say $250k so I could cover my salary and benefits and have ~$100k to make stuff

A year of doing that would be pretty fun

[rapid geode]

yeah. i neever have money and time off at the same time haha

[tardy badger]

Yeah, my time off is limited

My day job wants at least 4 extra hours a week from me

Luckily they pay me my hourly rate for those 4+ hours

I’m pretty lucky in that regard

My friend works for a similar company and they have to work at least 45hrs before they start getting paid OT. And it’s only for the time after 45hrs that they get overtime

[rapid geode]

the law here is 44h then you get 1.5x your wage. if you are on salary it is different.

so when its a crunch and you work 12-16h/day here, 6 days a week, you can make some good money. it only costs you your soul 😛

[tardy badger]

Sounds like working most jobs lol

I’m really just looking forward to the last two big holidays for the year

US Thanksgiving, and Christmas

Halloween is here, I have a costume this year which is a dragon rider inflatable

It’s pretty hilarious

Anyway, i still have to get things working on a breadboard hehe

[ebon dew]

Happy Halloween 🎃

[spice moss]

hehe

[dusty citrus]

I can't tell, is this a coilwhine of there's something wrong with this unit?

[glad ruin]

Sounds to me like an issue with the fan.

Or just some gunk caught in it.

[dusty citrus]

Also I don't get what just happened. I was putting a repo as private, then all my GitHub repos did disappear

[ebon dew]

That's not coil whine that's a fan bearing.

If that's a new PSU send it back that's definitely abnormal for a brand new PSU. You can take the risk of voiding the warranty (always a fun thing) and replacing the fan yourself but be warned those PSU capacitors should be respected for being almost lethal. You touch the wrong thing and you'll have a really bad day.

Were you using Github's website to delete the repo or using CLI?

To delete a repo via Github's website you have to jump through a couple hoops and click confirm multiple times as well as type in the repo and path you want deleted. It's a very specific thing so doubt you did it accidentally that way.

[dusty citrus]

All my repos are gone, except for a void repo of some time ago. They did disappear after I requested to change password.
What I did is go to settings, danger zine, change repo visibility, change to private

[ebon dew]

Maybe some kind of browser cookie issue? That's weird.

[tardy badger]

I’d like to share a clean gem from the old country https://youtu.be/GUEHfAtKT9o?si=buP11QXVePi3Xkuz

A funny halo + Monty Python mashup

I say old country because it’s from a different time on the Internet, 17 years ago

[dusty citrus]

I guess they're gone forever uh?

[ebon dew]

haha that was good

reminds me of Red vs Blue a little

[dusty citrus]

I don't know something weird happened
I have two accounts with the same otp, same username, but they have different email which are yet somehow linked

Luckly repos are not lost it seems

Anyhow the psu is brand new, I guess I'll have a call with amazon, thanks

[ebon dew]

[ebon dew]

great quality, looks delicious

[rapid geode]

um

id eat it

[jagged citrus]

where can i get the files for the planetary gears

I made this... thing

Also these candy taste like lacquer thinner

[rapid geode]

haha

anise?

[jagged citrus]

Definitely not

Its too synthetic, like chemicals

[rapid geode]

ew

like cheap black jelly beans?

[jagged citrus]

Yeah

[rapid geode]

yuk

i think there is a conspiracy to deliberately make cheap candy taste bad so that people will pay $4 for 5 cents worth of sugar

[jagged citrus]

Believable

[ebon dew]

Whew what a night. All out of candy here and turned the lights off. Got wiped out. I have a ton of trick or treaters every year.

[rapid geode]

i ate all the candy and told the kids to scram

[umbral phoenix]

I had two little kids come early, then nothing

There aren't usually many, but I'm sure the snow didn't help

[blissful roost]

Not seen a single kid at the office tonight... because that would be totally sus. 😛

[haughty solstice]

Yo that's where "And now for something, completely different" comes from!?

Incredible

[ebon dew]

Had maybe about 150-200 kids from 6pm to 9pm. It's a school night so things ended a little earlier than normal.

[tardy badger]

It technically comes from the Monty Python skit it’s dubbing but yeah

[haughty solstice]

Holy macaroni I got 3

Though we don't have any decorations up so that probably helped

[rapid geode]

i just went and stole all the candy from kids on the street. mmmmm

(i didnt do that)

alrighty, time for more keycaps

[ebon dew]

Had a good time 🎃

[rapid geode]

eep

monster

[tardy badger]

Trick or treating done. Phew 😮‍💨

[rapid geode]

give me all the mini mars bars please

[tardy badger]

Lol I’ll ask the kids

[rapid geode]

you dont ASK, you say you need to inspect them for razor blades.

[tardy badger]

Lol

[fickle aurora]

Or worse, malware laden USB drives

[rapid geode]

rfid chips in the kitkats

then you can track your kids coming in late

[ebon dew]

I didn't even keep any for myself plus ended up coming up short by about 50 kids. There were more this year than last year.

[pallid orbit]

I recognize that mask 😉

[ebon dew]

I got lazy and decided to do everything last minute this year and didn’t get the LED’s in the dreads in time but had the same exact idea as you. The way you pixel mapped them I did not think of but after seeing how great yours turned out I totally want to do it too.

[tiny oriole]

https://photos.app.goo.gl/UgV6foacL5AxwrRU6

My first Rpi project! A fun little idea to deal with unbidden cables in my desk. Turned out pretty well imo.

[pallid orbit]

I've found I'm going to be limited by the mask so I'm aiming to design and 3d print my own, I'm just terrible at 3d modeling 😆

at least for my needs

[ebon dew]

Also are you using the spotled app? It works pretty well on ios.

[pallid orbit]

nope, I don't want to create any 3rd party software dependencies if I can help it

[ebon dew]

I had a hard time seeing out of it at night but definitely more visibility than my dragon mask from last year where i could only see out of one eye at a time. Was the main reason for going with a different mask this year instead of trying to upgrade the dragon mask.

[pallid orbit]

yeah it's really dark, unfortunately for me with the blinking eyes in the front I could not see more than about a 1cm hole lol

[ebon dew]

It uses BLE so going to look into possible BLE hack for it to use Adafruit connect app, maybe.

[pallid orbit]

which is why I got a stereopi board and 2 cameras so I can start implementing stereo video streaming into my birdbath display that's inside, but to fit all of this I just really need a better frame

I work on crazy ambitious stuff all the time 😅

[ebon dew]

Ah thats a neat idea but for Halloween at night i dont see a camera and HUD being any better. Might need night vision. Now that would be cool and potentially super hero stuff. 😄

[pallid orbit]

next thing to implement but I need to do calibration and such for the stereo distortion offsets. about to help run a LAN event this weekend, too.

oh this is just for in general, not just cosplay/costume 🙂

I aim to have a fully functional tech suit with a variety of features in the next ~3 years

[ebon dew]

The tiny cameras aren’t known for their low light level prowess.

[pallid orbit]

I could use an IR light to project in front of me and switch between IR and color, I believe there's some cameras that do that. I'm still in my prototyping phase atm so I'm just experimenting for now

[ebon dew]

Oh heck yeah if you could figure it out to be functional that would be cool. They really are sick looking helmets to do projects with.

The flexible matrix in it is impressive too. I want to see if i can get it working on an nrf52840.

[pallid orbit]

this is what I cobbled together last year for my wearable PC - runs a win11 computer for ~8hr and there's a display on my back for presenting whatever I want on a full 1080p 15" monitor

before I dealt with any microcontrollers or learned how to solder

[ebon dew]

Just remove the included ble box and roll my own with an itsybitsy or ledglassesdriver board.

Oh wow, you have plenty of experience with prop projects then.

[pallid orbit]

I really don't never did anything like this before last year.

[ebon dew]

Same, my dragon mask was my first.

[pallid orbit]

the original goal was to project Beat Saber as I'm playing it with a VR headset, through a monitor on my back while my arms are lit up like the light sabers, and I needed a microcontroller to drive the LEDs, so I could create a virtual window into a virtual gameplay experience from the perspective of the viewer IRL

my only understanding for microcontrollers was raspberry pi, but the market was like $150-200 for an rpi, and I found out about MiniPCs

[ebon dew]

This was last year.

[pallid orbit]

then I figured out I could use a USB battery with power delivery to provide 12V to its usb-c power input on the miniPC, and then kind of went on from there

[pallid orbit]

I think I saw the blog/article about this! Super cool!

[pallid orbit]

this is the back of my v1 tech suit

and this cube is the entire PC

[ebon dew]

Have you looked into JP’s power washer hid project? Can make a VR gamecontroller. The power of a pi would be much better suited than a microcontroller.

[pallid orbit]

I've since changed out the PC 'core' and attach it to the small bag using velcro

yup, I saw that the other day. I've got plans to make my own controller, but I also have an Ultraleap I'm going to use for hand tracking

[ebon dew]

Who needs a cyberdeck when you are the deck with a full res monitor haha that’s awesome!

[pallid orbit]

and I've worked in VR apps professionally before in contracts, and in my own projects, so I already have my own custom API for handling hand tracking and poses

which I built as a generic wrapper around the oculus quest's hand tracking API

[pallid orbit]

this was my entry for the cyberdeck contest last year on hackaday 🙂

I didn't enter again this year since I had too much going on, but will probably next year

[ebon dew]

Oh wow ok. You’re way above my level then. I hope to read about the dual camera project someday.

Same, I didn’t even enter digikey’s hack-a-pumpkin challenge. Just didn’t have the energy or time.

[pallid orbit]

yeah I feel that

[ebon dew]

Didn’t make a single hacktoberfest PR either. I missed half of october on vacation. 😔

[pallid orbit]

can't always output all the time, need breaks every now and then

[rapid geode]

tired

haha

[bright veldt]

why dont we have screws like this where there is a small-ish bit at the end of the screw that could be used to hold it in place as we try to screw it into a hole?

[blissful roost]

Like a woodscrew..

[bright veldt]

but better

[rapid geode]

O_o that exists in many different forms. some are self drilling, some are just a pilot. usually for sheet metal but also machine screws

[pale veldt]

Anyone here know how to drive a lcd display with a raspberry pi 4?

need understanding on how i would need to connect said display to the pi

[late fulcrum]

There are two main ways: the obvious one, just plugging the LCD into the HDMI connector (this works with HDMI capable displays, or with an HDMI converter). The other is using the MIPI/DSI connector to connect a display with a ribbon cable (this works with DSI capable displays). There's also a composite video output available on the headphone jack (this works with composite video capable displays). After that, for things like I2C or SPI displays, you'd talk to it via the GPIO pins the same way you'd drive such a display with a microcontroller.

[pale veldt]

thank you!!!

[ember token]

Are those keyboard keycaps?

[pale veldt]

@late fulcrum if i were to go for portability with a good resolution display, will a I2C display fulfill that?

[idle iron]

what kind of risk do i have if i use multiple pins to try and increase the amp? if i put diodes on each pin will that lower risk of something breaking?

[dusty citrus]

Is it possible to work an Adafruit ESP32-WROOM-DA-N8 with a Adafruit HUZZAH32 – ESP32 Feather Board (pre-soldered)?

So I can not solder the wroom?

[ember token]

You want to remove the ESP32 on the HUZZAH32 board and put the ESP32-WROOM on it instead?

[ember token]

pre-soldered means that the 0.1 breadboard headers are soldered on the board already.

[dusty citrus]

Chat gpt said this

I just don’t understand

[ember token]

ChatGPT is wrong

[dusty citrus]

Ok

What do I solder it to?

So I can connect it to my pc?

The wroom?

That’s all I need then

[ember token]

I'm not even sure you can replace the ESP32 module on that circuit board. Have you checked that the pins on the new ESP32 module exactly match the HUZZAH board?

[dusty citrus]

Chat gpt said yes

[umbral phoenix]

ChatGPT is not a source of knowledge, it makes up things #welcome message

that dual-antenna module is designed to be incorporated into new board designs, not necessarily retrofitted onto other boards... even if the pinout is the same, desoldering the old and soldering the new could be challenging depending on skill and equipment

[dusty citrus]

Ok thanks

Lol the welcome updated when I rejoined the server

I’m a beginner so I’ll just probably go with a pico w for web server or c3 hmmmmm

[umbral phoenix]

Arduino or CircuitPython?

[dusty citrus]

microPython

I don’t even know what circuit python is

This will be my first microcontroller

Besides microBit

[umbral phoenix]

CircuitPython is based on MicroPython, some differences https://docs.circuitpython.org/en/latest/README.html#differences-from-micropython

see also: https://learn.adafruit.com/welcome-to-circuitpython/what-is-circuitpython

[dusty citrus]

Thx

[ember token]

ChatGPT can say whatever you want it to say.

It will make up everything

[dusty citrus]

What esp32 would you recommend for a simple web server that run’s online through the global internet

[umbral phoenix]

any with wifi will do... ESP32-S2 is a solid choice, also ESP32 (no native USB) or ESP32-S3, Pico W too (not sure of relative levels of support for those in MicroPython though)

[ember token]

Pico w

[dusty citrus]

💪

I’ll add micro sd adapter for extra storage too

I have lots of code for my site

I’ll see how it works

[rapid geode]

oui

Most of the I2C displays are small, low resolution affairs. However, there are some DSI displays that have decent resolution and can make a compact sandwich with the Pi.

Here's one example: https://www.waveshare.com/4.3inch-dsi-lcd.htm

It includes touchscreen capability as a bonus

[glad ruin]

There are also the pimoroni hyperpixel displays, but those are DPI and they use all of the GPIO.

Has there been any news on “Adafruit "My Little Hacker" ESP32-S2 Development Board” recently?

[lusty fossil]

Credit card question: I have already purchased the hotel and airfare for this trip, to be clear. However, I am wondering if there is any utility in getting another credit card to use on a trip I am taking next year internationally. Specifically a card geared towards travel. I was looking at some and it seems like most of the benefits are on hotels and airfare which I have already purchased with cash. I haven't existing credit card which has acceptable benefits but nothing travel related. I assume that they don't just give you perks for spending money in a foreign country. I was planning on doing Travelers checks and local cash while I'm there but it might be good to bring my existing credit card, or this theoretical new card, for emergencies. I just have one credit card that I pay off every month and I don't really care about the benefits I just like the protection of credit, so I am kind of ignorant about how all of this works

[umbral phoenix]

Yeah, credit cards are good for the fraud protection, carrying less cash / fewer traveler's checks, (and to take advantage of the float, assuming it's paid off monthly), ideally you'll want a card with no Foreign Transaction Fees. Exchange rates will vary card-by-card too but that can be a bit opaque. Perks of different cards are subjective... points, miles, cash back,... just depends on what your priorities are. Oh, and annual fees for credit card vary wildly, from $0 to infinity and beyond - for a minimal use backup card, probably want a no-annual-fee (which will have minimal perks).

[lusty fossil]

So if my existing card is good in the country I'm going to, stick with that?

[umbral phoenix]

If the card is good for you generally, and it works in the country (most any VISA/MC should be fine in most places), little reason to get a new card. Maybe check with the credit card company (website or customer service) if there are any caveats if the card is lost or stolen, or the number used fraudulently internationally... like how quickly do you have to report it, etc. - I'm not sure if rules could be different outside of home country). Canceling a card is a pain if you have auto-pays.

[patent hemlock]

if you only have one card, i would actually recommend getting a second as a backup in case the first is non-recoverable: there's going to be some sort of delay in processing (like it's night-time and you may want to do something like eat 😄 )

if your bank issues cards, that's also really handy and usually doesn't involve a fee

[dusty citrus]

You can also use multiple cards especially if they're free or give bonus credit.
Although since it's on argument I'm now somewhat curious to know why eu banks refuse to open you an account if you have an us bank

[burnt tendon]

There's a lot of offshoring / know your customers / money laundering stuff out there, it's probably that?

But, yah, if you have auto-pay stuff it's super-handy to not take that card with you when you travel in case it gets lost/stolen. It's also handy to have a second card in general because banks will generally move quickly, it's still 24-hrs-ish.

Crossing country borders can cause weird stuff, e.g. when the US was still heavily involved with magnetic stripes and EU had fully moved over, getting an EU card with a mag stripe was ... interesting.

And yah dono, Traveler's Checks haven't been a thing as much, as in with some places you are going to get a blank look because they don't comprehend the idea of one, but I guess that depends on what country you are from and visiting.

c.f. in the US where some municipalities had to remind folks that some people don't have bank accounts and maybe businesses shouldn't be allowed to go fully cashless vs Germany or India.

[umbral phoenix]

I travel to various countries, take several credit cards with me, an ATM card (watch the exchange rates and fees at ATMs), and cash (hotel room safe, except for what's needed on a given day). And wallet in front pocket if I'm anywhere where pickpocketing might be a risk.

If you do get a new card, let the issuer know you'll be traveling, to avoid fraud-detection-based card denials at check-out.

[patent hemlock]

"wallet in front pocket" should be a default -- if you're sitting on it, your pelvis isn't extactly level and that skews your lower back (even a tiny bit builds up over years)

[tardy badger]

The reason is compliance with US tax laws. They don’t want to deal with it for people still holding US citizenship

US citizens overseas are required to still pay taxes on the income they earn outside the US and file a tax return. The US government requires any foreign bank that has US citizens as customers report on balances, transactions, etc.. to try and stop people from being tax cheats

[tardy badger]

Neat, Texas Instruments is expanding their campus down the road from me to include a second 300mm wafer fab for analog and embedded semiconductor products

Called LFAB2

[olive dome]

And they are doing it even-though their inventory is going way up, perfect.
I can't wait to see those chipset price drop

[umbral phoenix]

true, my wallet is only 3/8” thick, plus any cash, and I don’t keep it in the back if I’m going to be sitting for any length of time. I don’t know how people manage the 1”+ wallets, front or back

[patent hemlock]

even that is enough to put your back 1 degree or so off of "true"

[urban arrow]

Yes I was told by a chirpractor years ago to not sit on that thing in a back pocket one side...

[blissful roost]

I don't pay attention to such things.. there's no way a wallet should cause any problems, except maybe a patch of numbness for a while. lol

[tardy badger]

It’s been extensively studied

There’s a medical term for back issues caused by putting your wallet in your back pocket and sitting:

Wallet Neuritis

I keep my wallet in my front pocket for two reasons:

1. I don’t like the feeling of lumps in my back pockets when I sit or stand. Even the pocket material bunching up makes me uncomfortable.

2. Pick pocket safety even though it isn’t guaranteed to stop it from happening

[blissful roost]

Just seems odd, considering the spine is never in "perfect" alignment.

There's constant deviation.

[patent hemlock]

the body wasn't built for long periods of sitting, much less doing that with everything out of whack 😏 (case in point right here)

[tardy badger]

There is what’s called a “neutral” position for the spine and constant pressure from wallets, cans of chew, etc.. can cause an imbalance in your muscle natural “neutral” position.

It can cause a lot of issues to have your lower back muscles not the same length

I had to do 3 months of physical therapy to fix issues due to scoliosis in which the muscles in my lower back essentially kept my hips slightly tilted to a point where it affected my ability to complete my military fitness tests for my sit-up portion

[blissful roost]

Thank goodness I'm too old for that 😛

[tardy badger]

I could run a 13 minute 2 mile (3200m) run, my 60-70 push-ups

[patent hemlock]

hah - "old" is what got me (slightlhy collapsed disk and a bone spur)

[tardy badger]

But sit-ups, my lower back would lock up causing some intense pain and I couldn’t complete it

[blissful roost]

Ooff!

I'm in surprisingly decent condition for my age... but I could use a new hand. 😛

[tardy badger]

I am pretty disadvantaged musculoskeletally. I have hyper mobility which causes scoliosis, cool shoulder tweaks, occasional pinched sciatica which lasts for weeks

Also as I get older and my boyish metabolism slows down, small changes in weight exasperate those things

I turn 31 really soon and I tell ya, the issues I have due to hyper mobility make me feel 50-60

[blissful roost]

Seems I've been lucky, besides self-inflicted damage. 😅

[patent hemlock]

oh, i'm in that category (or was ... i aged out 😏 )

[blissful roost]

I got a medical discharge as a recruit. 😅

[ebon dew]

weird timing on the conversation. I just started designing a 3D printed wall mounted cane holder for my mom with musculosketel issues.

[blissful roost]

A worthy project indeed. 👍

[ebon dew]

6 hour print for an extremely rough prototype. the cane is one that has a funky bend to it, almost like a question mark looking cane.

once i get the angle then will make the inner walls more of a cylinder cut out shape.

[blissful roost]

🙂

[ebon dew]

She keeps leaving her cane around and then forgets where she put it before she leaves the house. Having to walk around looking for something when she already has trouble walking just aggravates the issue. I have the technology, I got this. 🙂

[rapid geode]

what you need is to add bluetooth and gps to the cane to track it

[tardy badger]

Wow, Arm acquired a minority stake in Raspberry Pi Trading, Ltd. (Raspberry Pi)

I guess that’s old news (11hrs or so ago)

But definitely fascinating

[burnt tendon]

Hey, I'm going to a physical therapist and his office is right near all of the semiconductor company offices and he assures me he sees a lot of people ... like ... um ... me.

And, dono, I feel like there's a completely under-appreciated category of stuff that 3D printing ought to enable in terms of adaptive technology.

Obv troublesome because it falls right along the boundaries of what the FDA wants to regulate as a medical device and all.

[blissful roost]

I thought I already dropped a link to an article here, but.. ehh.

Definitely very interesting.

[tardy badger]

I probably would have if I saw it earlier

[blissful roost]

I'm still disappointed that Nvidia didn't get the ARM acquisition.

[burnt tendon]

I mean, it's taking them farther and farther from that which they started out to do, understanding that there's two entities and all anyway.

[ebon dew]

Didn't Sony make a huge investment into Raspberry Pi last year with some ridiculous amount of like 3 billion?

[blissful roost]

I don't recall seeing anything about that.. but I miss things every day. 😛

[ebon dew]

I don't think it was Arm. Pretty sure it was Sony, I could be wrong.

[tardy badger]

Sony invested earlier this year

Arm announced their investment today

https://www.cnbc.com/amp/2023/04/12/sony-backs-raspberry-pi-with-fresh-funding-access-to-ai-chips.html

https://www.hackster.io/news/arm-invests-in-raspberry-pi-acquires-a-minority-stake-of-the-popular-single-board-computer-maker-495d1b78c390.amp

Both focused on AI and IoT

[ebon dew]

My mistrust of Sony goes back to CD's, DRM, and rootkits. Now they're investing in AI and IoT, excuse me if I'm not overly excited.

[umbral phoenix]

are hardbound college textbooks still a thing, or is everything online or softcover per-semester custom-printed course packets?

(going through all of my physical books, trying to figure out what to do with them)

[burnt tendon]

I mean, at this point, all of the books have been made obsolete by new editions such that there's no value.

Other than, you know, knowledge.

[umbral phoenix]

yeah, I assumed that one semester later, they would have no monetary value, but I kept them since the content is timeless

but today, how many (technical) college courses have hardbound books vs. semester-only workbooks or course packets vs. toitally online

[glad ruin]

There is.

[glad ruin]

Largely irrelevant to me for someone with a physical disability. I had an aunt who was quadriplegic; if I had a printer when she was alive I could have printed literally hundreds of things that would have improved her quality of life.

[late fulcrum]

Some really is. I have a textbook on auto repair that was originally published in the 1960s, and most of the content is still relevant today. I have several textbooks on varying subjects that haven't been obsoleted. Latin and APL haven't really changed. Other than changes in component availability and implementation preferences, vacuum tube circuits and power distribution are the same as they were a century ago. Other than prevailing theories and the biochemical underpinnings, even embryology and paleontology are about the same. And yes, I have (and read) textbooks on all of them.

[burnt tendon]

I mean there's also the self-help angle. Shoving files on a 3D printer and printing them is something that you can do safely with disabilities that would preclude machining parts or whatnot.

speaking of https://www.tomshardware.com/news/ny-bill-bans-3d-printers

[ebon dew]

Yeah only takes 1 bad apple to ruin it for everyone. Just because you can doesn't mean you should.

I've seen them around on reddit and I typically block anyone promoting them for that use. It's so dumb and a horrific accident waiting to happen at the very least. Don't go down that road, nothing good will come from it. That's my stance on them.

[shy orbit]

Guys im having trouble driving a neopixel. The onboard itsybitsy rp2040 works fine but when I add any they dont light up. I verified power ground and connections. Any ideas?

[shy orbit]

I dont get it. Why hinder progress. You going to ban my cnc mill too that makes actual guns?

[ebon dew]

Some of those WS2812B strips don't have the controller chip but every 7-10 LED's. Even though there are cut marks doesn't necessarily mean it'll work if you cut it at that spot. Something I've learned along the way. Not all LED strips are the same. Some have the controller built into the LED, some do not.

[glad ruin]

Alright, I'm not a mod, but I think we should drop this topic. While it is definitely an issue and is worth discussing, I don't think this server is an appropriate place to do so.

[shy orbit]

Hmmmm it did say cuttable every led

[ebon dew]

Looks like the tiny white arrow is in the correct direction for data flow too.

[shy orbit]

Im just getting nothing. Im wondering if i have to disable the onboard somehow

[glad ruin]

Din/Do likely means data in/data out, also if they were analog they'd need dedicated R, G, and B lines.

[ebon dew]

looks like GND, DI, 5V

[glad ruin]

Doubtful. You'll need to communicate with them to set the color(s) anyway.

[ebon dew]

and with the resistor every LED does look like the type with the controller built into each LED.

[shy orbit]

Well when i set neopixel[0] the onboard does change colors

[ebon dew]

Show the wiring on the itsybitsy too please.

[shy orbit]

Well yheres other stuff on there but its only 3 pins

[ebon dew]

Possible cold solder joint? Doesn't look like any solder bridges to me.

[shy orbit]

Green to gnd yellow to data orange to vhi with 4.8v

Ive soldered 3 up now

Scratching my head here lol. Are they more sensitive than normal leds? Am i burning them up or statically ruining them?

[ebon dew]

sounds about right, hmm

Can we get a closer picture of the board and pinouts next to them?

[shy orbit]

Yeah

Its just a photosensor. Teo switch imputs, and the neopixel

[ebon dew]

2nd breadboard is where you're doing common grounds, looks good.

[shy orbit]

Yuh

Try to solder another? Lol. Maybe my irons too hot lol

I feel like after 3 its somehow code. But the code is simple

[ebon dew]

I would start with the basics and just get the LED to work first, break it down in sections so you know it's not a hardware issue and then can focus on potential code issue.

[shy orbit]

Use a different library?

It kind already is, all other code is commented out

[ebon dew]

Are you using the neopixel library?

[shy orbit]

Yepp

[ebon dew]

You don't necessarily need to use VHI. You can use USB for power too.

[shy orbit]

Right but was gettin voltage. I can move it.

[ebon dew]

ok if you're probing and know it's getting voltage than nvm

Here's a neopixel simpletest for rainbow color. https://learn.adafruit.com/adafruit-neopixel-uberguide/python-circuitpython

Just change the number of pixels to 1

and the relevant board pins for the itstybitsy rp2040 (pretty sure that's what you're using).

[shy orbit]

i must have torched it. onboard runs that example fine

[ebon dew]

right but the point is to switch from onboard to pin # GPwhatever

take as close of a picture of the soldering on the neopixel strip as possible. maybe it is a cold solder joint or solder bridge.

[shy orbit]

Whoooo!

Can anyone name this connector from the cable to the board? Trying to find a replacement for the cable

[old peak]

Is it JST PH 2.0mm?

[hallow locust]

seems like a 4 pin connector, i think its jst but it only has 4 pins, never seen that

[late fulcrum]

JST come in a variety of pin counts.

[glad ruin]

I did a thing.

[stoic mesa]

almost certainly JST PH

You likely have to find the pin definitions in the LVGL files before you move to a different library.

Poor documentation is painful.

[shy orbit]

hey guys, i was tired last night and things were going poorly so i gave up for the night. i rewired my project today and everything seems to be working except my switch is not being read, ive tried the most basic ssketch and trieed moving to d10/9. i have a spdt 3 pos switch connected to 3.3v on the middle leg and 10/9 on the outer legs. this worked fine previously.

could i have fried the gpio pins? a1 is currently working

[sick apex]

you could've, you could have even gotten something too hot by shorting it at some point that it just slightly melted a trace in the board to the pin

or the part of the chip that is responsible for them

but in my experience rp2040s are quite resistant

christ

mine was letting out magic smoke and it still works fine

cause i wired something wrong

it could just be the particular one you got wasn't ship shape when you got it but it worked and passed tests then you did sumn a lil wrong and it sent it over the point of no return

electronics are weird

temperamental

[shy orbit]

got it. i was a dum dum and wired the middle leg to 3.3v instead of gnd lol

its always right after i ask that i figure it out hahahah but if i dont ask ill just be slamming my head against the desk, and i do. i hate asking xD

appreciate ya buddy

[solar kindle]

This is a similar cable from Duttek. Listed as "USB to PH2.0 Cable". It looks like the same pinout, at least.

[dusty citrus]

You may also find usefull this site:

[gentle tulip]

Hey everyone! ^^

I have a question.

I want to make a Orrery that can accurately tell me where the planets in our solar system are at any given time via an internet connection and the time and date.

What would i have to use for that?
Would the Pi Zero W work for this?

[tardy badger]

A pi zero w probably would work just fine

Though, you might as well try to use a pi zero 2W as they might be easier to get and will be a bit more powerful

[gentle tulip]

Nice!

How much bigger is the pi zero 2W?

Also i need a way to detect where the planets actually are on the orrery so maybe a way to connect light sensors or cameras?

I'm probably in way too deep with this project. :/

[tardy badger]

The pi zero and pi zero 2 are the same size

Thankfully the Pi zero and zero 2 have a bunch of GPIO that can be used for things like sensors

[gentle tulip]

That's great! ^^

[tardy badger]

There’s also an FPC connector for hooking up a pi camera

[gentle tulip]

Hm

Idk what's possible in terms of location detection

[tardy badger]

You could put a fish eye on it, do a long exposure of say a minute and try to do some image processing to determine rough location based on the stars and time

But you could also easily add a GPS/GNSS module

Lots of options

[gentle tulip]

Well it's gonna sit inside and GPS won't really work.

It would have to connect to the internet to get the time and date

And then calculate the positions of the planets or something

[tardy badger]

Use RTK instead

[gentle tulip]

RTK?

[fossil dawn]

you can get a kinda approximate position using the IP address. Or just ask the user to enter their location

[gentle tulip]

I don't need the position of the person on earth. /-\

I need the positions of all the planets in the solar system

So the Orrery is accurate

[fossil dawn]

ah lol 😆
In that case I really don't know but there has to be some kind of API or formulas to calculate that

[gentle tulip]

I emailed an Orrery site and asked where they get their data from, maybe they can help me. ^^

[fossil dawn]

maybe NASA has some public information about that 🤔

[tardy atlas]

is someone here familiar with Polymer charger - bq24074 ? I'm planning to buy one for my project, but I couldn't find specific Information's. can I program it with a microcontroller ?

[tardy badger]

RTK is used for calculating precise position indoors

[gentle tulip]

I didn't find something like that yet unfortunately

[gentle tulip]

Ohhhhh okay gotcha ^^

[gentle tulip]

https://api.le-systeme-solaire.net/en/
This looks promising

Do you think i should have the different planets driven by 9 different motors or one motor that drives all of the planets?

[whole jacinth]

that depends on whether you want to make it more of an electrical engineering project or a mechanical engineering project

[gentle tulip]

Well i was just thinking about what would be the easiest way to make it so the planets can be aligned to their current position without having to spin the main wheel for like an hour (idk how long it would actually take)

All the gears would probably look hella cool tho

[winter trail]

Does someone know why there's this white square printed on the back? Looks somehow unwanted. It's covering the print partly. Guess not much "love" has gone into this. 😅

[gentle tulip]

Production error prolly no?

Are you using it with Arduino or Circuit Python? If it's displaying code on the 2nd eyeball then could just be a code issue. Screen damage shouldn't prevent the code from executing the 2nd eyeball.

If you suspect a damaged part then you can only get official support for something like that via Adafruit's forum (or email). Recommend you post your issue in there.

This ain't normal right?
Pinecil knock off

the different tip "color"? that's normal

[late fulcrum]

Do you have pointers to mold making outfits?

[dusty citrus]

Is it?
Also at the touch looks different, if should be new so dunno
I thought it was oxidized or something

[ancient rivet]

can see same general thing on tips in adafruit shop, ex:

Oh I see thanks, what causes discoloration, machining? Just curious

Just got a pincil knockoff from AliExpress, it seems pretty unstable with temps, but feels nice

the tip of the tip is a different surface material than the rest of the tip.
Afaik the shiny part is chrome-plated. The tip of the tip is something else and even has lead-free solder on it from the factory.

Try it out: The solder will stick to the tip of the tip. But it won't stick to the shiny part.

Or do you mean that the entire thing looks coppery instead of silver? (or is that just weird colours in your photo?)

[dusty citrus]

Alright thanks
Anyhow the photo has just weird colours

Self promotion?

[burnt tendon]

I really wish reddit hadn't made "no self promotion" the thing it's become there.

[tardy badger]

Have a friend share it?

I am a casual shadow browser of Reddit, I don’t have an official account these days

[dusty citrus]

Hm, does anyone have any suggestions on glue guns?
Likely you can make something decent and cheap by stripping out a soldering iron
But I would like something that's already made

[tardy badger]

You can generally buy hot glue guns for less than $15
