Custom PC, Issue 227

Custom PC Issue 227This month’s Hobby Tech column dives into the capabilities of the Nvidia Jetson AGX Orin Developer Kit, sees what Retro Games Limited’s TheA500 Mini can do, and finishes with a review of the Amazon Smart Air Quality Monitor for smart home enthusiasts tied into the company’s Alexa ecosystem.

The Nvidia Jetson AGX Orin is a direct successor to the AGX Xavier, which I reviewed back in Issue 190. Like its predecessor, the AGX Orin – or, at least, its Developer Kit incarnation as-reviewed – packs a powerful system-on-module into a compact and actively-cooled casing with reasonable room for expansion, including a full-length PCI Express slot to one side.

Designed for on-device machine learning workloads, the AGX Orin includes a 12-core Arm Cortex-A78AE CPU and an Ampere GPU with 2,048 CUDA cores, 64 Tensor cores, and a pair of NVDLA V2 coprocessors. Add 32GB of LPDDR5 memory and 64GB of eMMC storage expandable via M.2 slot to the base, and you’ve got an absolute beast of a box and one I very much enjoyed putting through its paces.

TheA500 Mini, meanwhile, is also Arm-based – but considerably less powerful. Designed as a follow-up to TheC64 Mini, reviewed in Issue 180, TheA500 Mini swaps Commodore’s popular eight-bit for its Amiga successor. With 25 games pre-loaded – 26 if you download a bonus game and pop it on a USB flash drive – it’s not exactly an exhaustive look at the best the Amiga scene had to offer, but a fun nostalgia trip nevertheless. Special mention must also be given to the bundled peripherals, an optical tank-style two-button mouse and a replica of the CD32 gamepad – both of which can be used on a standard PC as USB peripherals.

Finally, the Amazon Smart Air Quality Monitor is a compact sensor designed to tie in to the company’s Alexa smart home system – to the point where it lacks any form of display of its own, relying entirely on in-app reports and a simple LED on the front which lights up when the air quality drops. Reporting a total of five environmental conditions – particular matter 2.5 (PM2.5), volatile organic compounds (VOCs), temperature, humidity, and, oddly, carbon monoxide (CO) – the sensor is discrete but appears to suffer from a few teething troubles.

Custom PC, Issue 136

Custom PC Issue 136This month’s Hobby Tech column for Custom PC magazine reviews a next-generation version of the Fuze Powered by Raspberry Pi kit, previews the upcoming MinnowBoard Max from Intel, and publishes an interview with Sam ‘MrSidC64’ Dyer, author of Commodore 64: A Visual Commpendium – the spelling a deliberate pun on ‘Commodore,’ if you were wondering.

First, the Fuze T2 review. I’d already looked at the original Fuze, courtesy its inventor Jon Silvera, back in Issue 124, and little has changed from the aerial view: it’s still a robust steel case inspired by the BBC Micros of the 80s, designed to house a keyboard, Raspberry Pi and a break-out board for the general-purpose input-output (GPIO) pins, sold either on its own or as a bundle with child-friendly electronics tutorials and a handful of simple components for experimentation. Looking in more detail, however, shows that plenty has changed: following feedback, Jon has redesigned to case to include the ability to mount the Pi sideways to prevent little fingers pulling out the SD card, added Lego-compatible holes to the side, and best of all included a four-port USB hub with integrated power supply that provides proper 5V/500mA ports while simultaneously powering the Pi itself. A much-improved GPIO break-out board is another welcome addition, featuring compatibility with existing add-on boards as well as integrated analogue-to-digital and hardware pulse-width modulation (PWM) pins – something the Pi alone sorely lacks.

The MinnowBoard Max, meanwhile, is easily recognisable as a new design entirely. Designed to replace Intel’s old MinnowBoard, reviewed back in Issue 122, the Max features a proper 64-bit dual-core Atom processor with 64-bit UEFI implementation – meaning that the limited compatibility of its predecessor is a thing of the past. The design is more compact, the entire platform more accessible to beginners, and as usual it’s entirely open in both software and hardware – even the UEFI BIOS is based on Intel’s open-source code. For those who find ARM development boards too much of a stretch after years of x86 programming, it’s certainly worth investigating and I was impressed with the pre-release prototype I was provided. Sadly, the release of the final production model has hit a few last-minute delays – although I’m expecting stock of both the dual-core and single-core variants to appear in the channel before the end of the year.

Lastly, my interview with Sam Dyer. A graphic designer by trade, Sam launched a Kickstarter campaign to crowd-fund a new coffee table book all about the software available for the Commodore 64, his first real computer. As a massive Commodore fan myself, I was a backer and when the book arrived earlier this year I knew I would have to write about it. Sam was kind enough to give me some of his time to answer questions about his early days of computing, the technology behind capturing the images that make up the book, and its at-the-time impending successor Commodore Amiga: A Visual Commpendium – which yesterday closed funding with a massive £130,000 raised from fellow Commodore fans. Yes, including me.

All this, plus a variety of words written by people who aren’t me, can be yours now with a trip to the newsagent or supermarket, or from the comfort of your home or office via Zinio or similar digital distribution services.
