This month’s PC Pro includes a review of something a little out of the ordinary: the open-source, microcontroller-powered OpenScope MZ oscilloscope from Digilent.
Based on the original OpenScope and manufactured following a highly successful crowdfunding campaign, the OpenScope MZ is designed primarily for education and hobbyist use. While it lacks the bandwidth you’d need for professional use, it makes up for it in ease of use: it can be connected to your wireless network for tangle-free operation, includes cables which mate handily with the 2.54mm headers common to hobbyist electronics, and uses cross-platform software capable of running on everything from a powerful desktop to a low-end smartphone.
Better still, the OpenScope MZ is, as the name implies, open: the hardware design, firmware, and software are open source, allowing anyone with the knowledge to add features or customise the device as they see fit.
More information on the OpenScope MZ is available on the official website, while you can read my review in full by picking up a copy of PC Pro Issue 279 from your nearest newsagent, supermarket, or digitally via Zinio and similar services.
The CubieBoard 6, to start, was kindly provided by low-power computing specialist New IT. Despite its high version number, the device felt like a blast from the past as soon as I opened the box: it’s based on almost exactly the same form factor as the original CubieBoard and its successor the CubieBoard 2, after which creator CubieTech moved towards bulkier designs with up-to-eight-core processors. A return to form is no bad thing: CubieTech boasts that the CubieBoard 6 can be used as a drop-in replacement for most CubieBoard 1 and 2 projects.
For the review, I ran the device through the usual raft of benchmarks and gave it a direct comparison to the Raspberry Pi 3 with which it competes. One interesting shift from the norm, though, was in thermal imagery analysis which revealed that the CubieBoard’s SATA-to-USB bridge chip draws considerable power even when no SATA device is connected – something that would have been difficult to ascertain any other way.
The OpenScope MZ, meanwhile, is a very different beast – though, technically speaking, also a single-board computer of sorts. The successor to Digilent’s original OpenScope, the OpenScope MZ is a hobbyist- and education-centric open-hardware dual-channel oscilloscope with additional functionality as a function generator, power supply, and logic analyser. Where it differs from its competition, though, is in the presence of a Wi-Fi chip which allows you to connect to the device remotely – which, coupled with the browser-based software used to drive the thing makes it compatible with everything from Windows desktops to a Raspberry Pi or smartphone running the Linux variant of your choice.
Finally, The Bitmap Brothers Universe is a fantastic coffee table tome charting the history of the titular giants of gaming familiar to any Amiga owner present or former. Written based on painstaking interview work by Duncan Harris and published by Read Only Memories, the bulk of the book is in single-colour print with reproduced concept art and illustrations breaking up the prose; the exception comes in the form of colour plates on glossy black paper, which use a series of neat post-process effects in an attempt to simulate their appearance on an old cathode-ray tube (CRT) display – the way they were originally meant to be seen.
All this, and the usual interesting things written by others, can be found on the shelves of your local supermarket, newsagent, or digitally via Zinio and similar distribution services.
