Build

I'm interested in trying to do useful things with small Single Board Computers (SBCs) and electronics:

• I want to use SBCs to offload simple processing for self hosted services,
• I want to use microcontrollers to make smart sensors and for Internet of Things applications.

Current I am using Raspberry Pi Zero W, Raspberry Pi Zero 2 W, ESP-01S and ESP-32.

Raspberry Pi Notes

• Pi Zero W Set Up

  Installing an OS and getting online.
  

• Static IP Address Configuration

  Configuring a static IP address
  

• Setting up a Webserver

  Installing NGINX webserver
  

• Configuring a Static Website

  Copying a website to be served by NGINX
  

• Acquiring Data from a Temperature and Humidity Sensor

  Using Python and Bluetooth Low Energy mode to read a smart sensor
  

• Setting up my Pi Zero 2 W

  Set up as a second Pi-hole and monitoring with Prometheues
  

• Pi Zero 2 W Setup Part 2

  Reinstalling the set up after finding the Pi unresponsive
  

• Pi-hole Version 6 Update

  A slightly more complicated update
