Does the 7” touchscreen draw significant resources?
I'm trying to use a seven inch touchscreen monitor with my pi4, but the program I'm running is lagging. I was wondering if it draws enough resources to make the pi slower or have slight delay, could anyone help me?

SSH into Pi 3A+
How can I ssh into my Pi 3A+ via USB? I have been following this video:
https://youtu.be/7nDJPidKSPA?si=PZm3fRWedA0UtWqu
I’ve tried both putty and Debian on WSL, but when I try to ssh, it cannot resolve the hostname. I tried to ssh into 127.0.0.1 and the same thing happened. When I try to view my network connections in Control Panel or usb devices in Device Manager, the PI does not appear as an RNDIS gadget. I can SSH through wifi, but I want to avoid that because when I move back into my dorm, it will be difficult to get my device added to the internet whitelist. What can I do now?

Won't boot from NVME
I used Raspberry Pi Imager from a Raspberry Pi OS running on an installed SD card to image a fresh Raspberry Pi OS image onto a connected NVME SSD drive. It completed and said it was successful after verifying the image that was installed.
I removed the SD card with intention to boot from the NVME.
It won't boot, though I changed the boot order to begin with NVME.
I plugged in another Raspberry Pi instance that is on a USB drive and it will successfully boot from USB after failing to boot from the NVME.
The NVME is seen by the Raspberry Pi, but as seen in GParted, the two partitions created on the NVME are "unknown" and either damaged, unformatted, or a device entry is missing, or something.
1. Can RPi Imager not install Raspberry Pi OS on an NVME drive?
2. If so, how should it be done, and how should the drive be prepared first (partition table, unformatted or with a filesystem)?
3. If not, what would be the best way to install Raspberry Pi OS onto this NVME drive so that it will boot from it?
4. Image shows Gparted reproting the NVME drive partitions
5. Can Raspberry Pi OS handle being installed on a drive that is ~ 500 GB, or does it have to be smaller instead?
6. I don't want to "copy" an install from an SD card, rather install "fresh" on the NVME
7. Oops, need to mention this is a Raspberry Pi 5
8. It appears the filesystem setup on the nvme drive is corrupted or otherwise wrong.

SSH Pi Connection
I am currently working with a raspberry pi 4 and a load cell sensor.
The sensor is hooked up to the correct GPIO pins on the pi, but I need to install the correct packages to access them through python.
I am currently accessing the pi through an SSH connection, but when I try to install a necessary package "pip3 install HX711", i get an error that "this environment is externally managed."
I've tried running this connection through a VM and the install worked, so why am I getting this error for just this package? Other packages installed just fine. Nothing on the internet has worked/ been useful. Thanks!

Doesnt show up Website correctly
Hello, I have a Raspberry Pi Zero 2 W with a Display.
I want to host a Website in the localhost and then show it on the Display.
To make the Website run, I gotta run 2 different commands (node server.js and http-server) and when I make this using:
bash #!/bin/bash sudo gnome-terminal --working-directory=/home/kiski/SpotifyDashboard/ -- http-server sudo gnome-terminal --working-directory=/home/kiski/SpotifyDashboard/ -- node server.js sleep 2 chromium-browser --app=http://127.0.0.1:8080/It just shows this Page: (view attatched pic) But weirdly it still shows the correct icon. How can I fix this? OS: Raspberry Pi OS

Open CV on Rpi 5 very sluggish
Im trying to hookup 1, if possible 2 logitech usb webcam (1920x1080). The camera works fine in vlc and processing for pi but I want to use python and the openCV library. This however does not work that smoothly, the video is lagged and also seems choppy. Anyone know any particular settings I should investigate ? (there seem to be a lot and i'm not that familiar with this) or any other tips to get it working smoothly with python ?

Raspberry Pi 4 Push Button to run program
Hello, i want to use a push button to run a program on the Raspberry Pi 4.
For example, when I just click the button I want the program to run, I don't want the user to keep holding the button, I just need them to press it once and then my Python program will run.
What button should I order (if anyone has any experience) and if anyone has some good circuit configuration to connect the button to the GPIO pins, i'm not that experienced in the electrical side of things.
Thank you!

https://forums.raspberrypi.com/viewtopic.php?t=345542
Seems like I am formatted to MBR (Idk what this means I know sysadmin but not storage management) and limited to 2tb, how can I "change to MBR" (without formatting hopefully but doable) or otherweise make all 4tb available?

Pi 5: How to add "lcd_rotate=1" to startup
I have a raspberry Pi 5 with Ubuntu server 23.10 installed with raspberry pi imager. My display is setup vertical so I need to manually do "echo 1 | sudo tee /sys/class/graphics/fbcon/rotate_all". A guide said this:
If you want this to happen automatically when you start your system, you need to modify your boot loader configuration to give it the correct options. In /etc/default/grub add fbcon=rotate:1 to the GRUB_CMDLINE_LINUX line:
GRUB_CMDLINE_LINUX="fbcon=rotate:1"
(Don't forget to run sudo update-grub after changing this file.)".
But I don't think my setup uses grub right? I've also tried setting it inside "/boot/config.txt" but that doesn't work either.

Powering Pi 5 via USB-C in Gadget Mode and Additional Peripherals
I'm planning to use my Raspberry Pi 5 in device/gadget mode via its USB-C port connected to my computer. At the same time, I want to connect a mouse to one of its USB 3.0 ports.
Given that I won't be using the official Pi 5 charger because the USB-C port will be occupied for gadget mode, can the Pi 5 still draw enough power from the computer's USB-C connection to both run efficiently and power the connected mouse through its USB 3.0 port?
_(Assume my Computer has a USB-C Port that can provide 100W, I am mostly asking if this is within the Pi's capabilities)_
Thanks in advance for any insights or advice!

Humidity safe sensors
Hi all,
This would be my first Raspberry PI project, but I have extensive experience with embedded systems (10+ years ago), and have 10+ years of professional software engineering. I am currently looking into building a environment control system with a Raspberry, but I have several questions.
## Question 1
This project doesn't require too much power:
- I think 15-20 sensors/switches, persisting the data in some form (SQlite would be great).
- Expose a website with some graphs, and metrics
So it seems a Raspberry 5 would seem overkill, although I could re-use this PI for another project later this year.
Any tips on how to attach so many sensors in a sane way to the PI would also be welcomed.
## Question 2
None of the sensors I found seems to list safe temperate & humidity operating ranges.
Quite soms of the sensors I want to use have exposed PCBs, so I am afraid exposing them to high humidity is safe.
For example:
- Pi Camare 3 NoIR (cannot have any light during cycle), is it safe to operate outside or in humdity that sometimes ranges towards 80-90%? If not, what are some solutions?
## Question 3
What are some ways to package this in a sane way? I mean I don't mind a lot of long wires with sensors coming out of the PI, once it's properly installed it would not get detached/re-attached for long times. However if I want to keep the Raspberry PI out of the high humidity enviroment, I would need to work with long cables. Including a ~2m ribben for the camera (or two).
Thanks in advance!
Looking forward to all feedback, and ideas and getting started wtih my PI adventure.

In regards to Pi's 5 HID Capabilities
I have a short one:
As far as I know, the Pi 5 has two USB Controllers.
I am interested in having SIMILTANEOUSLY one USB Port act as a Host and receive input from another Device (Mouse in particular) and another one to act as an HID device and emulate a Mouse, Keyboard etc..
Can that be done? (I reckon so) In specific, what Ports would provide me the flexibility to use as HID? The Pi 4, for instance, has only that Capability on its USB-C Port. For the Pi 5 I cannot find any information online (if you know where I can find it, some hard manual, post that too so I can use it for the rest of my questions).
Thank you π lovers.

how to connect motors for a drone to a battery on a breadboard
Im pretty rusty with raspberry pis as i have been focused on react.js lately. But I have just started a project where I make a drone run on a raspberry pi. I have took out the motors from an old drone I had and stripped the wires so I can just plug them into a breadboard. Can anyone help me be able to control the motor by using a gpio input but powering it with a battery? I can send pictures and elaborate, just ask! Thank you!
