Custom PC, Issue 209

Custom PC Issue 209In this month’s instalment of my regular Hobby Tech feature, I take a look at the new Raspberry Pi Compute Module 4 family, Nvidia’s lower-cost Jetson Nano 2GB, and Sid Meier’s Sid Meier’s Memoir! – a book with what must be the most well-fitting title in history.

The Raspberry Pi Compute Module 4 is, as the name suggests, a successor to the Raspberry Pi Compute Module 3+ and Compute Module 3 ranges – themselves designed as a follow-up to the Raspberry Pi Compute Module, which took the core technology from the Raspberry Pi single-board computer and placed it into a system-on-module (SOM) form factor.

In my two-page review I take the new Compute Module through its paces, take a look at the redesigned and considerably cheaper carrier board, and warn of one major caveat: the redesigned module ditches the SODIMM form factor of its predecessors, meaning it’s not backwards-compatible with earlier carrier boards without a third-party interposer board between the two.

The Nvidia Jetson Nano 2GB, meanwhile, isn’t as identical to the original Nvidia Jetson Nano reviewed back in Issue 191. While, yes, the headline change is the drop from 4GB to 2GB of RAM, there are other modifications – including the loss of a hidden slot for an optional Wi-Fi card, fewer and slower USB ports, and the dropping of the second MIPI Camera Serial Interface (CSI) port added to its bigger sibling in a mid-stream refresh.

Finally, Sid Meier’s Memoir! – named in the style of the man’s games like Sid Meier’s Civilization and Sid Meier’s Pirates! – is a potted history of one of the pioneers of strategy gaming’s career, as told to author Jennifer Lee Noonan. It’s a text-heavy tome split into roughly chronological chapters, and absolutely fascinating – even if it does finally put to bed the myth of Gandhi’s overflow bug in Civilization.

Custom PC Issue 209 is available now from your local supermarket, newsagent, or online with global delivery from the official website.

Custom PC, Issue 191

Custom PC Issue 191This month’s Hobby Tech column takes a look at Nvdia’s first-ever entry into the maker market with the Jetson Nano, guides the reader through assisting the Internet Archive with its Sisyphean task, and takes a look at the Xiaomi Wowstick cordless screwdriver.

First, Nvidia’s offering. While the original Jetson TK1 single-board computer was sold through the since-departed high-street electronics outlet Maplin in the UK, its near-£200 price tag meant it wasn’t of much interest to the pocket-money shopper. Its successors in the Jetson family have been successively more expensive, culminating in the £1,199 Nvidia Jetson AGX Xavier reviewed last month. The Jetson Nano, by contrast, is just £95 – £101.50 if you include shipping – and is specifically aimed at makers and tinkerers.

The board uses a system-on-module (SOM) on carrier design, dominated by a massive heatsink. Although it’s perfectly possible to view the device as a souped-up and considerably more expensive Raspberry Pi, general-purpose computing isn’t Nvidia’s primary market: instead, it’s aiming to bring a new generation of developers into the CUDA GPU-accelerated computing ecosystem by using the Jetson Nano as a jumping-off point for deep learning and machine intelligence projects, including its own Jetbot autonomous robot platform.

The guide, meanwhile, walks the reader through using almost any PC to assist the Internet Archive with its goal of storing all the world’s information for immediate retrieval. Written as I was firing up a Warrior – the name given by the Archive Team to its distributed data capture systems – to assist with the archiving of the last bits of Google+ before its closure, the step-by-step instructions will let anyone contribute to the not-for-profit effort.

Finally, the Wowstick comes from a company better known in the UK for its cut-price smartphones: Xiaomi. Designed, as with much of the company’s output, to give a premium feel, the USB-rechargeable electric screwdriver is aimed at fine electronics work rather than flat-pack assembly – and does a surprisingly good job of it. Only limited torque for locked-down or larger screws and a terrible case whose tiny magnets are improperly attached let the bundle down.

For the full run-down on all this and more you can pick up Custom PC Issue 191 from your nearest newsagent or supermarket, or snag a digital copy from Zinio or similar services. Alternatively, a new subscription offer will get you the next three issues for just £5 – renewing at £25 every six issues if you don’t cancel beforehand.
