@Homoshrexual's comment on '(Request) Pihole With Button'

https://rdrama.net/h/slackernews/post/188267/contest-5000mb-reward-whats-in-the

A user asked me the below.

Hey, did you use any guides for setting up your pie hole and/or installing the button?

Was interested in making one of these as well.

Any tips or w/e would be appreciated, thanks!

This was my response. which is ~~probably~~ definitely rslurred but w/e

!codecels roast me

No Guides, but happy to give tips, and follow ups where things are unclear.

Button is pretty cool for sure... but you can do everything you need to do from your computer and phone.

A pihole does not protect you unless you set it up as your DNS on your router.

I would also recommend setting up a vpn to your home network using openvpn that way you can take your protection on the go, itll protect you from getting throttled by your cell phone provider too

Parts

Get a raspberry pi (here is fine https://www.raspberrypi.com/)
- get a case/fan if you are so inclined but I would consider it extra
- will come with an sd card and an sd card reader
- should come with a power cord
Button https://www.amazon.com/dp/B09KZK8SXQ
Wires https://www.amazon.com/dp/B01EV70C78
Breadboard https://www.amazon.com/dp/B0BNH7LYH3
resistor https://www.amazon.com/dp/B01GQFVSXK

Config Pi

Download the Raspberry Pi Imager from here https://www.raspberrypi.com/software/
Install pi lite on the SD card
- During Install configure the thing for wifi and ssh
- Set up a user for yourself on there and a password
Put the SD card into the Pi (contacts towards the board)
Start up the Pi and ssh into it
Install Pihole (follow these instructions https://github.com/pi-hole/pi-hole/#one-step-automated-install)

Code

Look its probably right... but how you set this thing up makes a difference
Put this on your Pi maybe call it buttonscript.js
{YOUR USER HERE} needs to be swapped out for the user you created

const fs = require('fs');

const Gpio = require('onoff').Gpio;

const { exec } = require('child_process');

// GPIO pin number

const buttonPin = 17;

const logFilePath = '/home/{YOUR USER HERE}/buttonscript.log';

// Setup the button GPIO as input

const button = new Gpio(buttonPin, 'in', 'falling', { debounceTimeout: 200 });

// Function to disable Pi-hole blocking for 5 minutes

function disablePiHole() {

const timestamp = new Date().toISOString();

const logMessage = [${timestamp}] Button pressed. Disabling Pi-hole for 5 minutes...;

console.log(logMessage);

fs.appendFile(logFilePath, logMessage + '\n', (err) => {

if (err) {

 console.error('Error writing to log file:', err);

}

});

exec('pihole disable 5m');

}

// Add event listener to the button

button.watch(disablePiHole);

// Cleanup GPIO on process exit

process.on('SIGINT', () => {

button.unexport();

process.exit();

});

Service

This thing needs to start back up when power fails so you need to set it up to do that
go here cd /etc/systemd/system/
run this to create it sudo nano buttonscript.service


[Unit]
Description=Button Script
After=network.target
[Service]
ExecStart=/usr/bin/node /home/{YOUR USER HERE}/buttonScript.js > /home/{YOUR USER HERE}/buttonscript.log 2>&1
WorkingDirectory=/home/{YOUR USER HERE}/
Restart=always
User={YOUR USER HERE}
[Install]
WantedBy=multi-user.target

save and exit nano
run this sudo systemctl enable buttonscript.service
run this sudo systemctl start buttonscript.service

Circuit

find your pinout, I am showing a 4b there are others
3.3 to a rail on the + side of the breadboard at the top using these wires https://www.amazon.com/dp/B01EV70C78
in that top rail, put the resistor in
resistor to the left hand side on maybe the top row of the breadboard
gpio 17 to left side on that row using these wires https://www.amazon.com/dp/B01EV70C78
button to left side on that row use the breadboard wires there
other terminal on the button to the right side of the breadboard
ground to right side on that row using these wires https://www.amazon.com/dp/B01EV70C78
