welcome

Raspberry Pi magazine is back again, bringing with it the final part of the tutorial we started last issue that showed you how to turn an old Xbox controller into a retro arcade machine. When you last saw us we’d just finished showing you how to hack the hardware and this issue we’re going to show you how to add a bunch of retro ROMS so you can play to your heart’s content. Swipe left to get started. There’s plenty of other tutorials that you might find useful too including how to boot a Pi3 B+ from USB and how to access a Pi Zero from your laptop. Finally, our regular Python column will show you how to Stream to Twitch from your Raspberry Pi. Editor Get inspired Discover the RasPi community’s best projects Expert…

xbox zero arcade pt 2

Right, so you’ve managed to get your Pi safely ensconced in a controller and all wired up – all you need now are some videogames to play. For this section of the tutorial we’re going to be using the RetroPie emulator. By the end of this tutorial, you’ll be able to play a number of games directly from your Raspberry Pi, provided that you legally own the ROM files, of course. The whole process is as easy as installing the software onto your SD card and then copying across any games that you want to play. If you’ve already got Raspian installed on your Pi, you can install RetroPie alongside it – or you can dedicate the whole disk to the software if you’d rather. 01 Install RetroPie inside Raspbian If you’ve already started…

pipecam

Sometime in 2014, Fred Fourie saw a long-term time-lapse video of corals fighting with each other for space. That piqued his interest in the study of bio-fouling, which is the accumulation of plants, algae and micro-organisms such as barnacles. Underwater documentaries such as Chasing Coral and Blue Planet II further drove his curiosity, and, inspired by the OpenROV project, Fred decided to build an affordable camera rig using inexpensive and easily sourceable components. This he later dubbed PipeCam; head to the project’s page (https://hackaday.io/project/21222-pipecam-low-costunderwater-camera) to read detailed build logs and view the results of underwater tests. Are power and storage two of the most crucial elements for remote builds such as the PipeCam? It has been a bit of an ongoing challenge. Initially, I wanted to solve my power issues by making…

boot your pi 3 b+ from usb

This tutorial explains how to take a USB mass-storage device, such as a flash drive or hard drive and boot up your Raspberry Pi 3 B+ using it. Once everything’s configured, there’s no longer any need to use an SD card – it can be removed and used in another Raspberry Pi. The benefits of this are that you can increase the overall storage size of the Pi from a standard 4GB-8GB to upwards of 500GB. A further benefit is that the robustness and reliability of a USB storage device is far greater than an SD card, so this increases the longevity of your data. Before you begin, please note that this setup is still experimental and is developing all the time. Bear in mind too that it doesn’t work with…

access a raspberry pi zero using a laptop

There’s no doubt that the Raspberry Pi boasts a wide range of resources – software and hardware which can be used for computing, programming and creating exciting and engaging projects. There are numerous add-on boards and components to expand the capabilities of the Pi. A lot of these require access to the command line or the GUI via a screen, available in a range of sizes, styles and colours. To use your Raspberry Pi you also require a keyboard, mouse, power supply or USB battery. The Raspberry Pi Zero also requires additional conversion sockets to add the various components. This often means you must carry around an additional kit if you want to access your Pi away from your desk or on the go. This tutorial covers a step-by-step solution for using…

stream to twitch with a pi

On a hackathon a year ago, we decided to build a 24/7 life-streaming device. Among other things, we learned how to create a Twitch-streaming device from a Raspberry Pi – and now so can you! With cheap high-res camera sensors, fast and affordable internet connections and hardware-accelerated HD video encoding, it’s no wonder live video-streaming blew up. People stream games, real-life events, tutorials and even the most boring things, like driving to grab some food from McDonald’s – there are new purposes for streaming being invented every day, and if you find a novel and interesting subject, viewers will come. Talking of viewers, they are one important aspect of modern livestreaming: find your audience and interact with it. On streaming platforms, there’s usually a chat that viewers can use to message…
