Joy-Pi - Pi-Hole

Summary

Short writeup of using the Joy-Pi case with a Pi-Hole installation, used e.g. for the Open House demo

Requirements

• Operating system: latest Raspbian
• Packages: pihole

Description

Step 1

Install Raspbian and pihole according to their respective documentations

Raspbian Pi-Hole

Step 2

Currently the Raspi is configured to use the eduroam Wifi. In order to do so, modify the /etc/wpa_supplicant/wpa_supplicant.conf as follows:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=AT

network={
   ssid="eduroam"
   proto=RSN
   key_mgmt=WPA-EAP
   eap=PEAP
   identity="USER@HOST"
   password="PASSWORD"
   phase1="peaplabel=0"
   phase2="auth=MSCHAPV2"
}

Since there is a bug in the wpa_supplicant >= 2.8 when trying to connect to enterprise Wifis, downgrade to 2.4 or later, under wpa_supplicant for Raspberry Pi

Connect using

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

There is a Bash script in the /home/pi directory, periodically circling through different webpages (just using wget in an infinite while loop).

Access the Pi-Hole Frontend under pi.hole/admin

Step 3

To use some of the demos from the Joy-Pi Script Package (Joy-Pi.zip), namely those for the 7-segment and Matrix LEDs:

• Activate I2C and SPI

   sudo raspi-config -> 5 Interfacing Options, enable SPI, enable I2C 

• For the 7-segment display: install the Adafruit Python LED Backpack Package (Adafruit)
• For the Matrix LED: install the Luma LED-Matrix package (Luma)
