some uses for a raspberry pi computer – introduction

A Raspberry Pi is a small inexpensive low power computer that has numerous uses and hopefully there’s one that chimes for you. I don’t think you’d want to use a Pi for emails and web browsing – it’s a tad inconvenient when compared to a laptop or Chromebook. But that is one negative out of many positives. The Pi uses very little power; it’s silent; it can be left running 24/7. And perhaps because of its low price, I can dedicate this computer to a single task. I have four and this is not a world record – the RPi does however break a few world records.

Coincidentally the Raspberry Pi was designed here in Cambridge – just as my uni team was working with their uni team. When I first heard of it, I wasn’t sure it would rip through schools, though it pretty much already had! I scooped this interview with two of the Raspberry Pi’s designers.

Some of those uses for a Raspberry Pi
  • A RPi will run Home Assistant, a home automation server that manages the lights, the heating and more. A chunk of this website is dedicated to showing why that’s useful
  • I use one RPi to continuously display a web page showing all the information that my home automation server collects about train times, the weather, the amount of electricity and heating oil I’m using.
  • I use another RPi to run Octoprint, a server that allows me to control and keep an eye on a 3D printer. And it’s wonderful how much more functional that printer becomes.
  • A RPi can take the role of the printer server called CUPS. Old printers that don’t have wifi but CUPS connects them to the wifi and makes them available via Google Cloud Print. This same RPi has a second role to access to a disc where I can backup and archive files. This is network attached storage. Rarely do I copy a file with a USB stick.
  • There are other uses to toy with. You can use a Pi to run Volumio – a server that delivers all your stored music. It’s an excellent app, but these days I listen to streamed music and my stored MP3s and CDs are history.
  • You can use a Pi to run Kodi – a capable media server app that delivers your stored movies, music, photos to your TV. If your TV was a plain TV, Kodi would make it cleverer.
  • You can use a Pi to run Openhab, which like Home Assistant, is a home automation platform.
