95 <p>There’s something special about the comforting solidity of a coin-eating video game monolith, and nothing screams retro fun like a full-sized arcade cabinet sitting in the corner of the room. Classic arcade machines can be a serious investment. Costing thousands of pounds and weighing about the same as a giant panda, they’re out of reach for all but the serious collector. Thankfully, you can recreate that retro experience using modern components for a fraction of the price and weight.</p> |

103 <p>An arcade cabinet is much easier to make than you might expect. It’s essentially a fancy cupboard that holds a monitor, speakers, a computer, a keyboard, and some buttons. You can make your own cabinet using not much more than a couple of sheets of MDF, some clear plastic, and a few cans of spray paint.</p> |

107 <p>If you want a really authentic-looking cabinet, you can find plenty of plans and patterns online. However, most classic cabinets are a bit bigger than you might remember, occupying almost a square metre of floor space. If you scale that down to approximately 60 cm2, you can make an authentic-looking home arcade cabinet that won’t take over the entire room, and can be cut from just two pieces of 8 × 4 (2440 mm × 1220 mm) MDF. You can <a href="https://hackspace.raspberrypi.org/404?link=issue35">download our plans</a>, but these are rough plans designed for you to tweak into your own creation. A sheet of 18 mm MDF is ideal for making the body of the cabinet, and 12 mm MDF works well to fill in the front and back panels. You can use thinner sheets of wood to make a lighter cabinet, but you might find it less sturdy and more difficult to screw into.</p> |

115 <p>The sides of the machine should be cut from 18 mm MDF, and will be 6 feet high. The sides need to be as close to identical as possible, so mark out the pattern for the side on one piece of 18 mm MDF, and screw the boards together to hold them while you cut. You can avoid marking the sides by placing the screws through the waste areas of the MDF. Keep these offcuts to make internal supports or brackets. You can cut the rest of the pieces of MDF using the project plans as a guide. </p> |

123 <p>Attach the side pieces to the base, so that the sides hang lower than the base by an inch or two. If you’re more accomplished at woodworking and want to make the strongest cabinet possible, you can use a router to joint and glue the pieces of wood together. This will make the cabinet very slightly narrower and will affect some measurements, but if you follow the old adage to measure twice and cut once, you should be fine. If you don’t want to do this, you can use large angle brackets and screws to hold everything together. The cabinet will still be strong, and you’ll have the added advantage that you can disassemble it in the future if necessary.</p> |

125 |
|
|
|
126 |
|
|
|
127 <p>Keep attaching the 18 mm MDF pieces, starting with the top piece and the rear brace. Once you have these pieces attached, the cabinet should be sturdy enough to start adding the thinner panels. Insetting the panels by about an inch gives the cabinet that retro look, and also hides any design crimes you might have committed while cutting out the side panels.</p> |

135 <p>The absolute sizing of the cabinet isn’t critical unless you’re trying to make an exact copy of an old machine, so don’t feel too constrained by measuring things down to the millimetre. As long as the cabinet is wide enough to accept your monitor, everything else is moveable and can be adjusted to suit your needs.</p> |

143 <p>You can move onto decoration once the cabinet woodwork is fitted together. This is mostly down to personal preference, although it’s wise to think about which parts of the case will be touched more often, and whether your colour choices will cause any problems with screen reflection. Matt black is a popular choice for arcade cabinets because it’s non-reflective and any surface imperfections are less noticeable with a matt paint finish.</p> |

151 <p>Wallpaper or posters make a great choice for decorating the outside of the cabinet, and they are quick to apply. Just be sure to paste all the way up to the edge, and protect any areas that will be handled regularly with aluminium checker plate or plastic sheet. The edges of MDF sheets can be finished with iron-on worktop edging, or with the chrome detailing tape used on cars. You can buy detailing tape in 12 mm and 18 mm widths, which makes it great for finishing edges. The adhesive tape provided with the chrome edging isn’t always very good, so it’s worth investing in some high-strength, double-sided clear vinyl foam tape.</p> |

209 <p>We heard from an international team (Monica McGill , USA; Rebecca Vivian, Australia; Elizabeth Cole, Scotland) who represented a group of researchers also based in England, Malta, Ireland, and Italy. As a researcher working at the Raspberry Pi Foundation, I myself was part of this research group. The group developed METRECC, a comprehensive and validated survey tool that can be used to benchmark and measure developments of the teaching and learning of computing in formal education systems around the world. Monica, Rebecca, and Elizabeth presented how the research group developed and validated the METRECC tool, and shared some findings from their pilot study.</p> |

|
216 |
|
|
|
217 <p>Those of us who work or have worked in school education use the word ‘curriculum’ frequently, although it’s an example of education terminology that means different things in different contexts, and to different people. Following Porter and Smithson (2001)<sup>1</sup>, we can distinguish between the<strong> intended</strong> curriculum and the <strong>enacted</strong> curriculum:</p> |
|
|
|
218 |
|
|
|
219 |
|
|
|
220 |
|
|
|
221 <ul><li><strong>Intended curriculum</strong>: Policy tools as curriculum standards, frameworks, or guidelines that outline the curriculum teachers are expected to deliver.</li><li><strong>Enacted curriculum:</strong> Actual curricular content in which students engage in the classroom, and adopted pedagogical approaches; for computer science (CS) curricula, this also includes students’ use of technology, physical computing devices, and tools in CS lessons.</li></ul> |
|
|
|
222 |
|
|
|
223 |
|
|
|
224 |
|
|
|
225 <p>To compare the intended and enacted computing curriculum in as many countries as possible, at particular points in time, the research group Monica, Rebecca, Elizabeth, and I were part of developed the METRECC survey tool.</p> |

233 <p>METRECC stands for <strong>ME</strong>asuring <strong>T</strong>eache<strong>RE</strong>nacted <strong>C</strong>omputing <strong>C</strong>urriculum. The METRECC survey has 11 categories of questions and is designed to be completed by computing teachers within 35–40 minutes. Following best practice in research, which calls for standardised research instruments, the research group ensured that the survey produces valid, reliable results (meaning that it works as intended) before using it to gather data.</p> |

|
|
|
240 |
|
|
|
241 <p>In their pilot study, the research group gathered data from 7 countries. The intended curriculum for each country was determined by examining standards and policies in place for each country/state under consideration. Teachers’ answers in the METRECC survey provided the countries’ enacted curricula. (The complete dataset from the pilot study is publicly available at <a href="http://csedresearch.org">csedresearch.org</a>, a very useful site for CS education researchers where many surveys are shared.)</p> |

249 <p>The researchers then mapped the intended to the enacted curricula to find out whether teachers were actually teaching the topics that were prescribed for them. Overall, the results of the mapping showed that there was a good match between intended and enacted curricula. Examples of mismatches include lower numbers of primary school teachers reporting that they taught visual or symbolic programming, even though the topic did appear on their curriculum.</p> |

257 <p>Another aspect of the METRECC survey allows to measure teachers’ confidence, self-efficacy, and self-esteem. The results of the pilot study showed a relationship between years of experience and CS self-esteem; in particular, after four years of teaching, teachers started to report high self-esteem in relation to computer science. Moreover, primary teachers reported significantly lower self-esteem than secondary teachers did, and female teachers reported lower self-esteem than male teachers did.</p> |

261 <h2><strong>Adapting the survey’s language</strong></h2> |
|
|
|
262 |
|
|
|
263 |
|
|
|
264 |
|
|
|
265 <p>The METRECC survey has also been used in South Asia, namely Bangladesh, Nepal, Pakistan, and Sri Lanka (where computing is taught under ICT). Amongst other things, what the researchers learned from that study was that some of the survey questions needed to be adapted to be relevant to these countries. For example, while in the UK we use the word ‘gifted’ to mean ‘high-attaining’, in the South Asian countries involved in the study, to be ‘gifted’ means<em> </em>having special needs.</p> |

277 <h2>Let’s keep this monitoring of computing education moving forward!</h2> |

278 |
|
|
|
279 |
|
|
|
280 |
|
|
|
281 <p>The seminar presentation was well received, and because we now hold our seminars for 90 minutes instead of an hour, we had more time for questions and answers.</p> |
|
|
|
282 |
|
|
|
283 |
|
|
|
284 |
|
|
|
285 <p>My three main take-aways from the seminar were:</p> |
|
|
|
286 |
|
|
|
287 |
|
|
|
288 |
|
|
|
289 <h4>1. International collaboration is key</h4> |
|
|
|
290 |
|
|
|
291 |
|
|
|
292 |
|
|
|
293 <p>It is very valuable to be able to form international working groups of researchers collaborating on a common project; we have so much to learn from each other. Our Raspberry Pi research seminars attract educators and researchers from many different parts of the world, and we can truly push the field’s understanding forward when we listen to experiences and lessons of people from diverse contexts and cultures.</p> |
|
|
|
294 |
|
|
|
295 |
|
|
|
296 |
|
|
|
297 <h4>2. Making research data publicly available</h4> |
|
|
|
298 |
|
|
|
299 |
|
|
|
300 |
|
|
|
301 <p>Increasingly, it is expected that research datasets are made available in publicly accessible repositories. While this is becoming the norm in healthcare and scientific, it’s not yet as prevalent in computing education research. It was great to be able to publicly share the dataset from the METRECC pilot study, and we encourage other researchers in this field to do the same. </p> |
|
|
|
302 |
|
|
|
303 |
|
|
|
304 |
|
|
|
305 <h4>3. Extending the global scope of this research</h4> |
|
|
|
306 |
|
|
|
307 |
|
|
|
308 |
|
|
|
309 <p>Finally, this work is only just beginning. Over the last decade, there has been an increasing move towards teaching aspects of computer science in school in many countries around the world, and being able to measure change and progress is important. Only a handful of countries were involved in the pilot study, and it would be great to see this research extend to more countries, with larger numbers of teachers involved, so that we can really understand the global picture of formal computing education. Budding research students, take heed!</p> |

381 <p>Even after all that power tool sparking, this miniature device is capable of playing Minecraft at 1000 frames per second. Michael was set on making the finished project as thin as possible, so he had to slice off a couple of his Raspberry Pi’s USB ports and the Ethernet socket to make everything fit inside the tiny, custom-made case. This hacked setup leaves you with Bluetooth and wireless internet connections, which, as Michael explains in the build video, “if you’re a Mac user, that’s all you’re ever going to need.”</p> |

Careful crimping of cables and adapters ensures the mini iMac can be powered from a USB-C extension cable that feeds in under the screen, while the device also includes a single USB 2 port.”</p><cite>Barry Collins | forbes.com</cite></blockquote> |

403 <p>The maker also told forbes.com that this build was inspired by an <a href="https://www.forbes.com/sites/barrycollins/2020/05/19/the-free-operating-system-thats-identical-to-macos/#207d12682967">iRaspbian software</a> article from tech writer <a href="https://www.forbes.com/sites/barrycollins/#1d4da4f5d2b8">Barry Collins</a>. iRaspbian puts a Mac-like interface — including Dock, Launcher and even the default macOS wallpaper — on top of a Linux distro. We guess Michael just wanted the case to match the content, hey?</p> |

819 <p>Matthias came up with <a href="https://www.youtube.com/watch?v=XbJ5vT8FvXU">this solution,</a> which makes your Raspberry Pi blink its IP address, because he used a <a href="https://www.raspberrypi.org/products/raspberry-pi-zero-w/">Raspberry Pi Zero W</a> headless for most of his projects and got bored with having to look it up with his DHCP server or hunt for it by pinging different IP addresses. </p> |

826 |
|
|
|
827 <p>A script runs when you start your Raspberry Pi and indicates which IP address is assigned to it by blinking it out on the device’s LED. The script comprises about 100 lines of Python, and you can <a href="https://github.com/Matthias-Wandel/pi_blink_ip">get it on GitHub</a>. </p> |

835 <p>The power/status LED on the edge of the Raspberry Pi blinks numbers in a Roman numeral-like scheme. You can tell which number it’s blinking based on the length of the blink and the gaps between each blink, rather than, for example, having to count nine blinks for a number nine.</p> |

|
|
|
840 |
|
|
|
841 |
|
|
|
842 |
|
|
|
843 <p>Short, fast blinks represent the numbers one to four, depending on how many short, fast blinks you see. A gap between short, fast blinks means the LED is about to blink the next digit of the IP address, and a longer blink represents the number five. So reading the combination of short and long blinks will give you your device’s IP address. </p> |
|
|
|
844 |
|
|
|
845 |

|
846 |

|
|
847 <p>You can see this in action at <a href="http://www.youtube.com/watch?v=XbJ5vT8FvXU&t=2m1s">this exact point</a> in the video. You’ll see the LED blink fast once, then leave a gap, blink fast once again, then leave a gap, then blink fast twice. That means the device’s IP address ends in 112. </p> |

|
|
|
942 |
|
|
|
943 |
|
|
|
944 <p>While this build looks epic, it isn’t too tricky to make. First, Cedrick flashed the <a href="https://retropie.org.uk/download/">RetroPie image</a> onto an SD card, then he wired up a Raspberry Pi’s GPIO pins to the red console buttons, speakers, and the screen. </p> |
|
|
|
945 |
|
|
|
946 |
|
|
|
947 |
|
|
|
948 <p>Cedrick achieved audio output by adding just a few lines of code to the <code>config</code> file, and he downloaded libraries for screen configuration and button input. That’s it! That’s all you need to get a games console up and running. </p> |

1019 <p>NODE wanted to take advantage of the faster processor and up to 8GB RAM on <a href="https://www.raspberrypi.org/products/raspberry-pi-4-model-b/">Raspberry Pi 4</a> when it came out last year. Now that our tiny computer is more than capable of being used as as a general Linux desktop system, the <a href="https://n-o-d-e.net/node_mini_server3.html">NODE Mini Server version 3</a> has been born. </p> |

1029 <p>As for previous versions of NODE’s Mini Server, one of their main goals for this new iteration was to package Raspberry Pi in a way which makes it a little easier to use as a regular mini server or computer. In other words, it’s put inside a neat little box with all the ports accessible on one side. </p> |

1038 |
|
|
|
1039 |
|
|
|
1040 |
|
|
|
1041 <p>The latest design is simplified compared to previous versions. Everything lives in a 92mm × 92mm enclosure that isn’t much thicker than Raspberry Pi itself. </p> |

|
1042 |
|
|
|
1043 |
|
|
|
1044 |
|
|
|
1045 <p>The slimmed-down new case comprises a single 3D-printed piece and a top cover made from a custom-designed printed circuit board (PCB) that has four brass-threaded inserts soldered into the corners, giving you a simple way to screw everything together. </p> |

1055 |

1056 |

1057 <p>Another goal for version 3 NODE’s Mini Server was to include as much modularity as possible. That’s why this new mini server requires no modifications to the Raspberry Pi itself, thanks to a range of custom-designed adapter boards. How to take advantage of all these new features is explained <a href="http://www.youtube.com/watch?v=vgjVps6etYA&t=1m14s">at this point in NODE’s YouTube video</a>. </p> |
