Pi2 LAN
I'd like to get my Pi2 LAN up and running. I have zero experience with networking and raspberry pi's.
Right now I have four RIP2's plugged into an unmanaged dell 2848 powerconnect switch. I would like to be able to transfer files between them. Where do I start? The Pi's have all been updated and are running rasperian.

Current draw 0.5-1 A. dc motor. 5v power source. proFET
Ok so I have a DC motor with a 3.7V battery which draws 0.5 A on normal load. Turning two rotor blades. It is from an old hover robot toy.
I have this https://www.infineon.com/dgdl/Infineon-BTS410E2-DS-v01_01-en.pdf?fileId=db3a304331c8f8560131dcc9fc520e21
That I use for switching. It requires 4.7V from the main power supply to operate. So I have replaced the battery with my own batteries. I have run it with 6 and 9 V batteries. On different occasions of course.
I switch it using one of the 3v3 gpio pins on the rpi4, gpio24. Works perfectly.
My question is this, would one of the 5V pins be able to support the current draw of the motor? I could try it I guess because I think the flywheel diode or some of the other protective features would protect the pie but I thought I could ask first just in case.
I was told that it wouldn't be able to support the current draw. My assumption is that if it can't it would result in a V-drop, making the FET inoperable. I have seen people using transistors with 3v3 pins where they used I=0.016A to calculate R to not damage the pin, but is that the hard limit for A both in and out on all pins?
Any way, again, could the 5V output support approx 0.5-1 A draw, when being hooked up via the FET in the link?

TikTokLive + OBS + ChatGPT
I am using an rpi to make an Amazon alexa, seems like a pretty common project.
That's all done, it works well.
But during the process I had an idea.
There is a TikTokLive Library, that you can use to scrape comments from tiktok.
I have successfully been able to scrape comments from tiktok, send them to chatgpt, and get a response.
There is a tool called the "OBS websocket" that you can use to control OBS remotely, or with python from what I can tell.
I would like to flash the chatgpt response on OBS so I can live stream to tiktok and have live viewers interact with GPT with their comments.
Hoping to do the same thing with Dall E Api's

RPi sd card
Just bought this, but when I opened the RPi software on my laptop it said it didn’t see any storage I could use. I know this comes with an operating system, but doesn’t it also have storage? Does the sd card need to be plugged in to my pc and not my pi? Please help.

Pi Zero W headless setup with Raspberry Pi Lite Bookworm
I have this setup:
1. Debian Linux laptop / Windows 11 PC
2. Raspberry Pi Zero W
3. OTG cable
I'm trying to set it up to work in headless mode (will run Docker on it with Pi-Hole, and probably some other minimal container that doesn't use many resources).
I use RPi Imager from my Debian Linux laptop to burn the image to the SD card, by following the first 3 steps here (latest image of course, not what is there), and add an ssh file as well, on top of those instructions: https://www.ctrl-alt-del.cc/2020/01/mikrotik-pi-zero-pi-hole-advertising.html
Step 4 for Debian Bookworm does not work. Using ssh pi@raspberrypi.local I get ssh: Could not resolve hostname raspberrypi.local: No such host is known.
These steps do work for Bullseye, so a breaking change seems to have happened somewhere.

RFID Module with 20 to 30 cm range
Hey guys and girls,
I am working on my first real PI project. I already contributed in a robot project with ROS, but now I wanna do something from scratch. To break it down I need a mechanism to scan a RFID chip from a cats collar and open a lock on a successful scan.
So much for the context now the problem.
Since I am not an engineer and only do software development with very little interaction on the physical level with such technology I don't know how to find the right modules to fulfil my requirements.
I bought a cheep NFC module PN532 in hope to make a first sample and implement the logic and test around. Since the range of this module is around 5 cm if you are lucky I would need something with a higher range, since this is meant to allow access to a cat it should probably be somewhere between 20 - 30 cm. I don't know what prices to expect, but let's try to stay "cheep".

audio hat & display on gpio simultaneously
Trying to connect an audio hat & lcd touchdisplay to gpio pins and i'm getting issues.
- The display: https://www.waveshare.com/wiki/3.5inch_DPI_LCD
- The audio hat: https://www.waveshare.com/wiki/WM8960_Audio_HAT
When i connect one or the other they work fine, however when both drivers are installed, and both devices are connected i get no display. I still get display throught microhdmi port just not to the display powered off the gpio pins. The audio hat connects to the pins on pi, and the display sits on pins that are on top of the audio hat.
Looking like i might have to get a different display, but maybe not if you guys can help.

Welcome to... then Black Screen. RP4, status lights okay, config changes to no avail
Hi all. I'm trying to set up a RP4 but no matter what I do I can't get it to finish booting. My red status light is solid red and I've tried two different power supplies so I'm convinced it's not the PS. The green LED also flashes randomly, no pattern visible, so unless it's 1/2 flashes which I can't tell, I think the green LED is fine. After the welcome screen, the screen will go black and eventually the green light starts to die down (flashing very little to possibly even stopping). In addition my monitor makes noises which make it seem like somethings trying to connect, but nothing happens.
I've googled quite a bit since I've encountered it yesterday, and found several things I could try in config.txt between hdmi_safe, the hotplug, and hdmi mode (which I made sure to turn on separately from hdmi_safe to prevent other settings overriding). None of these worked, however I'm willing to try them again if anyone has any suggestions

Raspi 3B V1.2 as bootloader installer for nrf52840
Good day;
i want to use my raspi to install a bootloader on a board with a holyiot 18010 nrf52840 as the controller
however im completely inept when it comes to programming, so i dont know what i have to do
ive been sent this github link by someone, they dont have the time to walk me through that however, and i dont know what to even do as i have no prior experience with programming a raspi or anything
https://github.com/joric/nrfmicro/wiki/Bootloader#flashing-the-nrf52s-bootloader-using-raspberry-pis-gpio-and-openocd
i havent used the raspi before for anything, so its just as out of the box as it gets
if someone would be willing to walk me through this thatd be nice
also, feel free to ping me so i can answer quickly^^

Inky Frame with C++
Hi! I've recently received by Inky Frame 7.3 with a raspberry pi pico!
Unfortunately, I have no experience with either Inky Frame or Raspberry Pi (any)!
I want to program it in C++
I'm interested in having individual pixel control, ability to assign images to certain parts of the screen, and writing text with (hopefully custom) fonts!
How could I start?

Looking for a todo list/calendar eink display; Is Inky Frame 7.3 inch with pico w onboard for me?
I've been looking into this board: Inky Frame 7.3 With Pico w aboard!
Background: I'd like to make a todo list/calendar that I can look at at any time on my wall and have it updated through my pc! I am happy with making GUI applications using Qt Creator in C++, or really anything in C++! Would sending jpegs/bitmaps to Inky be viable over the network?
Details: I hate using Python but could suffer through it if C++ is inferior for some reason for this project!
Is this display + board combo for me? Would you suggest another? Thank you!!

When ever I run a python script my vnc connection disconnects?
This is my script
py
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM) # BCM numbering
pin = 37
GPIO.setup(pin, GPIO.OUT)
GPIO.output(pin, GPIO.HIGH)
print(f"Enabled GPIO {pin}")
time.sleep(1)
GPIO.output(pin, GPIO.LOW)
print(f"Disabled GPIO {pin}")
GPIO.cleanup()
I'm using vnc viewer, it's literally a fresh install...
