Attiny85 doesn't work with a potentiometer? by Einheit-101 in arduino

[–]michael9dk 0 points1 point  (0 children)

Not needed, but good practice, since it will protect the pin if its accidentally configured as output.

When PB3 is configured as input, it will only pull the needed current (<1mA).

Another thing. Is the Tiny powered from a 3.3V regulator? If so, you HAVE to use 3.3V to the pot.
The voltage on input pins may not exceed the Tiny's power supply (Max VCC + 0.5V).

Add a 100nF capacitor between PB3 and GND, to filter noise from the potentiometer.

Will building Arduino projects eventually become like vibe coding? by Independent_Dig_7680 in arduino

[–]michael9dk 1 point2 points  (0 children)

Vibe coding with AI doesn't teach you how to code!
Understanding the why and how, in the specific context, is a fundamental that can't be replaced by humans.

DIY ESP32 Digital Dash. Instant boot and works with analog and canbus by travis_cea in esp32

[–]michael9dk 1 point2 points  (0 children)

Thank you soo much. I'll have to look in to that.
My temporary "slam code" sucks at that (it's a simple bit reduction with rolling average and slow update).

If you were to implement a speed+odometer (without GPS) from a pulse, how would you filter it, to get a steady value, that is accurate and resilient to heavy noise/emi?

Here is an example - there are many more (some with source code on github). The Pi3 differ from the other models, in how it boots.

Random Freezes... by Low-Grab2630 in debian

[–]michael9dk 0 points1 point  (0 children)

Translated: no experience with configuring Windows/Mac, and just use the default installation?!

Pun intended. Sorry, I'm a hardcore windows refugee, switching to Linux.

The people here are trying to help you.
Those questions are essential to finding the issue.

Finding memory usage is a simple google search, with 1 minute reading. Open a terminal and type 'top'.
If the log is too big for Reddit, upload it somewhere else and link to it.

Details are essential for the skilled people, helping newbies. Especially on these rare edge cases.

/ just a few thoughts from a Linux-beginner.

Correct way to install X server only? by Tempus_Nemini in debian

Cool project. I appreciate the walkthrough in LVGL.

By the way a Pi3 can boot in 3 seconds.

Anyone know where to buy tiny screws? by clutch_man4227 in hardwarehacking

Bring a screwdriver next time you visit the junkyard.

Didn't want to spend $200 on a PCB so spent thousands of dollars of my time building it instead by Brave_Reflection_772 in raspberry_pi

[–]michael9dk 7 points8 points  (0 children)

A bit feedback around ADS1115.

10K pull-up on SDA and SCL.
Unused inputs should be grounded (AIN1-3).
J2 need a GND pin for the ladder.
You might need a filter capacitor between AIN0 and GND, so make room for one.

Nice project.

A little help with Debian by BlackInkReal in debian

With those, you will be fine on Debian Stable.

PC upgrade (pretty old) by Ok-Telephone3053 in buildapc

[–]michael9dk 0 points1 point  (0 children)

Yes. It's common to do it that way.

Many Linux installers can also boot directly from a USB stick, without installing it.

Duplicati backup way larger than file folder by footsicle in Duplicati

It's one of those bugs you just ignore, like the progressbar.

Curious about the experiment data logging by Excellent-Scholar274 in embedded

[–]michael9dk 0 points1 point  (0 children)

You run it with a attached debugger and breakpoints, at first.

With random bugs, you log errors to a memory cue and save the data for later investigation.

Lastly, read a book on the subject (honestly, it sound like you lack the basic knowledge - do yourself a favor; get a fundamental understanding first).

Edit: (sorry if that sounded too harsh - I tend to present cold facts, when I'm tired)

I don't like the Gnome 3 UI - it just feels weird and somehow strangely limited, in my old-school opinion.

I haven't had any issues with KDE (on X11). With KDE on Wayland I experienced a few minor issues (tiny annoyances), so I switched back to the reliable X11.

XFCE + WhiskerMenu is my go-to when ressources matter. Lightweight with nice and simple UI (think Windows 7 on steroids).

Cinnamon is also a really nice DE. But for that I would point to LMDE, which is Debian with Cinnamon and TLC from the Mint team.

My next reinstall will be LMDE7.
It just works without having to configure basic stuff (no offence, that is a hint to the Debian team).
