Ph Sensor Using ADS1115 - Raspi Zero W
Hi,
i need to connect Ph sensor to raspberry pi zero w, it requires an ADS1115 to convert signals.
can i connect Ph sensor's GND to ADS1115 and Raspberry pi with one cable? one cable going out from Ph sensor splits into two cables, one for ADS1115 GND and the other for the raspberry pi GND.

PiHole Not Resolving
Right, I've got PiHole installed according to the guides and I've got the interfaces configured correctly but only local sites will resolve. My devices report no internet connection if I connect them with PiHole as DNS, though I don't get any PiHole errors. I don't have much experience with networking in Linux so it might be something small.

Hunting Iron man ( or Batman) helmet
Hi! basically, I want to make Iron man(or Batman. depends mostly on stl's I will find) helmet with built in thermal vision, night vision, and possibly remote activator. I want to use it to play hide and seek in the dark, as well for simply having a cool gadget from movies. Problem is, that I have zero knowlage about Raspberry Pi, coding , and stuff like that. Only similar thingI have done is working animatronic head using Arduino. I really need someone to help me find parts and show me the basics of it.

Wiring external hdd to pi with the +5v and ground to power bank, data pins to pi
I want to connect an external hard drive to a Raspberry Pi via USB, but the hdd draws too much power. Thinking of isolating 5v+ and ground from the hdd's USB cable, connecting it to a power bank, and only linking data pins between the Raspberry Pi and the hdd
was wondering if there would be any problems. While i'm not sure, apparently i might have to wire the ground for the power bank, hdd and the pi's usb together?

PI 5 + NVMe hat + M.2 to SATA converter issues
So I'm trying to make a music server, and wanted to use a SATA HDD instead of the current external HDD I was using.
For that, I got my hand on a PCIe to NVMe hat, and a M.2 to SATA converter. The M.2 to SATA converter seems at least to be powered, since the leds on it flicker once while booting up, but the SATA disk doesnt seem to be detected. I enabled the PCIe port by having "dtparam=pciex1" in my \boot\config.txt, and don't know what I could be missing to make it work.

[SOLVED] Rpi Zero + Speaker pHat + python = freeze and bugs
Hello !
I'm making a project with the Raspberry Pi Zero and the Pimoroni Speaker pHat. I added a push button and i want the speaker to play a sound randomly in a folder when the button is pressed. I'm doing the logic in python and everything works but I have a weird bug when playing the audio.
In the command-line aplay ./redfr/Bonjour.wav works perfectly fine.
But in python if I do os.system("aplay ./redfr/Bonjour.wav &") it displays Using device: speaker-phat and freeze for many seconds before playing the sound, and it freezes again for few seconds. (I tried without the & and same).
So I tried using playsound('./redfr/Bonjour.wav') but it gives me an error i donĀ“t understand (I'll post it after because it's big)
I tried using pygame:
pygame.init()
soundfile = pygame.mixer.Sound('./redfr/Bonjour.wav')
soundfile.play()
This way it takes a very long time for the script to start and then I get this
pygame 2.5.2 (SDL 2.0.14, Python 3.9.2) Hello from the pygame community. https://www.pygame.org/contribute.html Using device: speaker-phatand it plays the sound, and if I press the button it plays the sound instantly. great right ? well not really because right after the sound played the program crashed saying Segmentation fault :/ Does anyone has an idea of what's wrong here ?

Help with Raspi pi pico
Hey guys,
i need some help with my raspberry pi pico. I just like to started with a project but first iĀ“ve wanted to learn some basic coding skills. But i canĀ“t programm my pico. I can run the internal LED with the blink.uf2 programm and say Hello World so the Tutorial worked. So iĀ“d like to write my own code to make a external LED blinking but in the Thonny programm i canĀ“t find the pico. I donĀ“t know which Interprter to use or which port to use. In the Shell thereĀ“s the Error: CoulndĀ“t find the device automatically. i tried it with my Windows PC and even with my Raspberry pi4. In both ways it wonĀ“t work. It would be great to get help from you and sorry for my englisch iĀ“m not a native speaker

[SOLVED] Can't import RPi.GPIO nor gpiozero properly without getting error
Hello, I want to do some testing for my upcoming project but for some reason I can't import any of the GPIO libraries without getting errors after running a simple python example code.
The first problem was that I couldn't use pip3 or pip without creating and running in a Python venv which isn't a problem but the other problems were confusing and I couldn't find proper solutions.
When I use gpiozero/RPi.GPIO without running as root it sends error RuntimeError: No access to /dev/mem. Try running as root!
When I use RPi.GPIO doesn't load the functions and I'm not able to use the library. ModuleNotFoundError: No module named 'RPi'
When I run in the code as root sudo python3 main.py it sends out an error ModuleNotFoundError: No module named 'gpiozero'
Code using gpiozero
python
import gpiozero as GPIO
from time import sleep
red = GPIO.LED(14)
while True:
red.on()
sleep(1)
red.off()
sleep(1)
code using RPi.GPIO
python
import RPi.GPIO as gpio
import time
gpio.setmode(gpio.BCM)
gpio.setup(14, gpio.OUT)
while True:
time.sleep(1)
gpio.output(14, gpio.HIGH)
time.sleep(1)
gpio.output(14, gpio.LOW)
It might be a rookie mistake since this is the first time using RPi5 GPIO in Linux server OS

Pi 4 external HDD loading 4k videos really slow on xfs and ext4 (ntfs worked fine)
Hi guys, I have a 4tb external hard drive from Seagate that I use for steaming (jellyfin). Previously the hard drive was in ntfs format which loaded all 4k videos directly with no problems, even fast forwarding there were no problems.
Unfortunately I had the problem that copying files via samba took forever 20-30mb/s but now with xfs I get a constant 110mb/s
Unfortunately I now have the problem that all the videos I play just take forever to load, strangely the videos all start immediately but as soon as you watch 20-30 seconds further the hard disk just stops reading? and it only continues after 1 minute.
i checked the hard disk with iotop and found that nothing happens after fast forwarding, nothing is read, just dead silence. nothing happens with top either, not much cpu usage.
Do you have any ideas?
