welcome

“Head-mounted displays are going to be like toasters,” said Dr Albert ‘Skip’ Rizzo, Director of Medical Virtual Reality at the University of Southern California’s Institute for Creative Technologies back in 2016. “You might not use it every day but everybody’s going to have one.” While Oculus Rift isn’t quite as ubiquitous as Morphy Richards just yet, there’s no denying that VR is certainly set to usher in an entirely new era of home entertainment. Our main tutorial this issue will help you join this technological revolution using nothing more than the amazingly versatile Raspberry Pi 3, an Xbox 360 controller and some Python code. So swipe on to get all “William Gibson” with your Pi. Also in this issue you can learn how to draw 3D text Minecraft and boot…

create a pi-powered virtual reality setup

Virtual Reality is huge now and has come a long way since the concepts and CGI visuals of Stephen King’s Lawnmower Man. It is one of the fastest growing areas of technology and you can now design models, explore new places and play games all within a virtual environment. A professional VR hardware package is expensive and will set you back several hundred pounds. However, it’s possible to emulate the VR setup up using a Raspberry Pi, Python-VRZero and a 3D graphics module, Pi3D. Now, this is purely for fun and learning, so don’t expect huge gaming PC frame rates, although some of the demos do peak at around 25-30 FPS on a Raspberry Pi 3. This tutorial shows you how you create a VR setup using the Raspberry Pi 3,…

tough pi-ano

Where did your inspiration for the Tough Piano come from? I started the Tough Pi-ano after talking with my aunt. My cousin loves music therapy, particularly playing the piano, but he has Down’s syndrome and his excitable therapy sessions can destroy instruments meant purely for gentle fingers. While I thought of a solution, he kept smashing every garage sale piano they were able to pick up and buy. I knew that each of those pianos was really just a series of inputs and a rather basic sound generator. Has it been easy getting the project from concept to working device? One year ago I started working on a version which used hardwood keys with the same proportions as a standard piano, but they were difficult to make in my local hackspace – so…

make a raspberry pi vpn access point

Anyone who has been abroad will know it’s a constant pain to have to deal with content that has been switched to the local language, not to mention certain states that censor some internet content. Fortunately there’s a way to evade these restrictions using the Raspberry Pi. In a few simple steps you can configure your Pi to generate its own wireless AP (Access Point) and keep it permanently connected to a VPN (Virtual Private Network) service of your choosing. All you need to do when travelling is bring your Pi and connect it to a working router and you’ll have your own private wireless network and connection. VPNs were originally designed to allow office workers to connect to their corporate intranet while away, over an encrypted connection. These days they’re more…

draw 3d text in minecraft using python code

Minecraft’s ‘Creative Mode’ is indeed a great mode to get creative with, but it’s a timeconsuming job placing blocks down into your world one-by-one. That’s why we put together a package which incorporates a range of modifications that enable us to execute Python scripts directly into a Minecraft world. McPiFoMo includes MCPiPy by ‘fleap’ and ‘bluepillRabbit’ of https://mcpipy.wordpress.com, and the Raspberry Jam Mod, developed by Alexander Pruss. We’ll also be using Minecraft Turtle, which was put together by Martin O’Hanlon of http://stuffaboutcode.com. That’s a lot of mods, but together they allow us to do with Minecraft on Linux what would usually have only been possible with the Raspberry Pi edition of Minecraft. As a prerequisite, we assume you’ve installed McPiFoMo from the link in the sidebar. THE PROJECT ESSENTIALS Minecraft (www.mojang.com/games) Python (www.python.org) McPiFoMo…

preserve your raspberry pi’s micro sd card

At some point during the lifetime of your Pi, you are likely to encounter a problem with your SD/ microSD card. If you’re lucky, this will be minimal; perhaps a reboot will fix it. If you’re unlucky, it could mean the end of your SD card, and the loss of all data on your Pi. The simple fact is that SD cards do not last forever. Flash storage, by design, has a limited number of read/write cycles. While error-correction software is built-in, and cards ship with larger-thandescribed storage to cover damaged blocks, eventually corruption will cause a problem. SD card corruption occurs in various ways. It might be due to a sudden variation in voltage during a read/write cycle or from being removed from the Raspberry Pi. Flash storage is also susceptible…
