Custom PC, Issue 205

Custom PC Issue 205This month’s Hobby Tech column opens with a look at the Raspberry Pi High Quality (HQ) Camera Module, Seeed Studio’s impressively feature-packed Wio Terminal development board, and Read Only Memory’s follow-up to game developer interview collection Britsoft, Japansoft.

First the Raspberry Pi HQ Camera Module. The third full revision of the Camera Serial Interface (CSI)-connected low-cost camera add-on for Raspberry Pi and compatible single-board computers – after the original Raspberry Pi Camera Module was replaced with a higher-quality Sony sensor upgrade – the HQ Camera Module is built around a 12.3-megapixel Sony IMX477 sensor, offering increased resolution and improved low-light performance.

The biggest change, though, is that the lens has gone: Instead of a small plastic lens pre-fitted to the sensor, the HQ Camera Module accepts C- and CS-mount lenses – the same type of lens you’d find for security camera sensors. Two lenses make up the official offerings – a 6mm wide-angle and a 16mm telephoto – with third parties selling various alternatives including microscope-style macro lenses.

The Wio Terminal has a sensor of its own, but it’s not a camera: it’s an almost-all-in-one development board built around Microchip’s ATSAMD51 system-on-chip. Packed into a plastic housing with 2.4″ 320×240 colour LCD, the development board includes buttons, joystick, buzzer, LED, light sensor, and an infrared emitter – but, oddly, no battery, which needs to be added using an external accessory which considerably increases the device’s bulk.

Perhaps the most interesting feature of the Wio Terminal, though, is its general-purpose input/output (GPIO) header: a 40-pin female header, it shares the Raspberry Pi pinout and allows the Wio Terminal to act as a standalone device or to be connected to a Raspberry Pi as a Hardware Attached on Top (HAT)-style accessory – though doing so without some kind of extension cable covers the sensors on the underside.

Finally, Japansoft is a follow-up to the impressive Britsoft which follows exactly the same format: selected bite-sized extracts from interviews with notable game developers, only this time – as the name implies – looking at the Japanese games industry rather than the British. Where Britsoft culled its material from interviews carried out for the 2014 documentary From Bedrooms to Billions, Japansoft isn’t an original publication either: everything within comes from John Szczepaniak’s The Untold History of Japanese Game Developers and is simply reformatted to match the style of Britsoft.

That’s not to say Japansoft isn’t worth reading, but it does mean that anyone who has already seen Szczepaniak’s work will find nothing new. It also makes no effort to fact-check any of the claims within, instead placing a warning that its contents do not represent “a verified factual account” of the history presented.

HackSpace Magazine, Issue 16

HackSpace Magazine Issue 16This month’s HackSpace Magazine includes a pair of my reviews, the first looking at a computer that’s also a ruler – because that’s not only a thing but the second thing of its kind to come from the same designer – and a new set of charitable Top Trumps-style collectable cards.

First, the ruler-computer. Designed by Brads Projects, the Digirule2 is – as the name suggests – a second-generation design of a compact microcomputer which is also a functional ruler. Printed onto a single circuit board and built around a PIC32 microcontroller, the Digirule2 is inspired by the classic MITS Altair 8800: its memory is displayed on a series of LEDs, and is programmed one bit at a time using push-button switches.

Where the Digirule improves on the Altair, aside from being considerably more affordable and not taking up a huge chunk of your desk, is in having memory slots for saving and loading programmes. These slots come pre-loaded with demonstrations ranging from simple reaction games to a neat persistence-of-vision hack, while the edges of the board are printed with measurements – in binary, naturally – in both centimetres and inches.

The cards, meanwhile, are something a little less technical but no less geeky. Designed by 8bitkick and sold by the Centre for Computing History to fund its restoration and preservation works, the Games Consoles Collectable Cards partner high-quality colour images of classic videogame consoles with statistics that can be compared for a nerdy game of Top Trumps. They also partner well with the Home Computers Collectable Cards, an earlier release now repackaged to match, though sadly the two decks use different statistics and thus can’t be combined into a single mega-deck.
