Custom PC, Issue 181

Custom PC Issue 181In this month’s Hobby Tech column I take a look at two LED-adorned educational electronics kits, the Kitronik :GAME ZIP 64 and the Kano Pixel Kit, along with Mark Hardisty’s latest retrogaming project, The Classic Adventurer.

Kitronik’s :GAME ZIP 64, which will henceforth be known as the much easier to both read and type Game Zip 64, is a clever little add-on for the BBC micro:bit educational platform. Designed to mate with the BBC micro:bit’s edge connector, the Game Zip 64 adds 64 individually-addressable RGB LEDs, a major upgrade on the single-colour 25-LED matrix on the BBC micro:bit itself, buttons to form a four-way directional control pad, two fire buttons, a piezoelectric buzzer, and – interestingly – a vibration motor.

While the sample Python programs – Snake and Pong – are pretty poor, Kitronik has produced a series of lesson plans around the device which are absolutely fantastic, and put the £40 asking price well into ‘bargain’ territory for anyone looking to move on from the built-in features of the bare BBC micro:bit itself.

The Kano Pixel Kit is, on the face of it, a similar device: a matrix of 128 LEDs – twice the number of the Game Zip 64 – dominate the front, but control is limited to a function dial and a couple of buttons. It’s also Kano’s first truly standalone product, eschewing the normal Raspberry Pi for an on-board Espressif ESP-WROOM-32 microcontroller. As with the Kano Computer Kit, the Pixel Kit’s software – which, sadly, is not available for mainstream Linux, despite coming in a Raspberry Pi variant – is fantastic, but its development cost is likely behind the eyebrow-raising £75 asking price.

Finally, Mark Hardisty’s latest project – after putting his groundbreaking tome on the history of Gremlin Graphics to bed and recreating some classic artwork in Inlay – is The Classic Adventurer, a magazine dedicated to the glory days of interactive fiction. Available in print and also, all credit to him, as a free-as-in-beer DRM-unencumbered PDF download, each issue is packed with brilliant art and fascinating articles ranging from interviews to reviews with some behind-the-scenes stuff thrown in for good measure. It’s a fantastic project, and definitely one to follow.

Custom PC, Issue 177

Custom PC Issue 177This month’s Hobby Tech features two different Raspberry Pi add-ons, one designed to get the best possible audio quality out of the popular single-board computer and the other designed to get the best possible audio quality into it, along with a review of Mark Hardisty’s Inlay in tradebook paperback format.

First, the let’s-play-high-quality-audio add-on: the Allo DigiOne. Reviewed in its Player format, which bundles the DigiOne S/PDIF hardware attached on-top (HAT) board with a Raspberry Pi 3, micro-SD card, power supply, and admittedly neat acrylic case – which, unfortunately, makes it really difficult to remove said micro-SD card – the DigiOne is designed to output digital audio over an RCA or BNC connector. Its primary selling point: as-low-as-possible jitter, claimed to be measured at 0.6 picoseconds – though its creators seemingly accusing optical outputs, which the DigiOne lacks, of having 4 nanoseconds of ‘jitter’ when they appear to actually mean ‘delay’ is disappointing.

The Andrea PureAudio Microphone Development Kit, by contrast, is less about the sound that comes out of a Pi and more about what goes into it. A bundling of a cheap off-the-shelf USB soundcard in custom plastic packaging with a PureAudio array microphone – the self-same design Asus used to give away with selected motherboards – the Andrea Electronics bundle originally came to me as the Speech Development Kit, full of promise about how Andrea’s clever audio library would bring crystal clarity to your applications and allow you to quickly and easily build applications you could control with your voice.

Considerable back-and-forth with the company followed, and by the morning on which the column was due with my editor a decision had been made: the Speech Development Kit, which was nothing of the sort and completely failed to deliver on its promises, became the Microphone Development Kit. While still below par – the biggest failing that, unlike the Windows driver that used to be bundled with the Asus version, the clever noise-reducing beam-forming and other-sound-enhancing Linux audio library which is the primary selling point of the kit can only be used in applications you write yourself, and will do nothing for applications like Skype or Audacity – it, at least, now sets a more realistic tone for would-be buyers.

Finally, something for the eyes. The creation of Mark Hardisty, whose A Gremlin in the Works was reviewed back in Issue 168, Inlay is a book about classic game cover art primarily concentrated on the eight-bit era. Where most coffee table books of this type simply reproduce the art as it originally appeared, Hardisty took a more challenging route: the book contains painstaking vector recreations of the original art, minus distracting titles and flashes, producing a derivative work which is clearer and crisper than anything you’ve seen before. My only regret: picking up the cheaper tradebook paperback edition, which lacks the wide format of the hardback edition and thus has less of each cover available for viewing.

All this, and the usual selection of interesting tidbits written by others, is available at your nearest newsagent, supermarket, or electronically via Zinio and similar services.

Custom PC, Issue 168

Custom PC Issue 168This month’s Hobby Tech column is taken up with a trio of reviews covering the pretty darn impressive Mooltipass Mini hardware password manager, Automattic’s Blog in a Box distribution for the Raspberry Pi, and Mark Hardisty’s A Gremlin in the Works.

Starting with the latter, A Gremlin in the Works is another fantastic coffee-table book from retro computing publisher Bitmap Books (the founder of which, Sam Dyer, I interviewed back in Custom PC Issue 136). Written by Mark Hardisty based on exhaustive interviews – and retaining the question-and-answer style of the transcripts, making for an accurate rendition of the subjects’ thoughts but a slightly tiresome read – the two-volume book chronicles the rise and fall of gaming pioneer Gremlin Graphics. As a massive fan of Gremlin’s output – to this day the intro music to Hero Quest brings joy to my heart, and I blame my sweet tooth on a Zool addiction – A Gremlin in the Works is a book I’d long been looking forward to reading, and I’m pleased to say it didn’t disappoint.

Blog in a Box, meanwhile, is an interesting beast. At its heart, it’s a single-purpose GNU/Linux distribution for the Raspberry Pi created by Automattic as a means of making it easier for people to run the WordPress blogging platform from the device. It’s not provided as a downloadable drive image, as with most distributions, though; instead, Automattic has written a cross-platform program which customises various settings – title, passwords, email accounts, things like that – and configures them so the Pi is ready to rock on first boot. It’s a neat idea, but one which still needs polish: I found the Linux version failed to run properly on my Ubuntu 16.04 desktop, and several features promised by the tool were disabled when the Pi actually started up. It’s a tool with promise, though, and I look forward to revisiting it should Automattic release an update.

Finally, the Mooltipass Mini. The brainchild of Mathieu Stephan, the Mooltipass Mini builds on its non-Mini predecessor to create a pocket-sized hardware password safe for all your accounts – or, at least, as many as will fit in 8Mb (1MB) of internal memory. The Mooltipass Mini is a tool for the adequately paranoid: passwords, though not usernames, are stored in the device’s internal memory under AES-256 encryption with the private key located on a removable smart card itself locked with a four-hexadecimal-character PIN. When a password is required, its entry can be found on the screen and the Mooltipass does its best impression of a USB keyboard by typing the account details in on your behalf – or, when the optional software is installed, filling in forms in browser windows automatically upon manual confirmation on the device itself.

Having long advocated for the use of password managers to promote high-quality password use and discourage password reuse, the Mooltipass Mini is a near-perfect companion. It addresses the majority of the problems with traditional password managers, like how to keep the encrypted database accessible while preventing its theft. While there are undeniable issues, such as the £61 (inc. VAT) retail price and the need to buy two so you have a backup to use if the primary one fails, it has become a part of my security arsenal – and one I feel comfortable using thanks to the project’s open-source nature for both the software and underlying hardware.
