In this months’ Hobby Tech column I take a look at the open-source, though not open-hardware, Bangle.js 2 smartwatch, dig deep into digital archaeology with some Dragon 32 floppy disk analysis, and read Microzeit’s Crackers II: The Data Storm.
First, the smartwatch. Back in Issue 218 I reviewed the SQFMI Watchy, a hacker-friendly but bulky smartwatch built around a low-power electrophoretic display. The Bangle.js 2 is a slicker, slimmer device which uses a colour Sharp Memory LCD panel – colour, yet still sunlight readable. Unlike the Watchy, though, it’s not a wholly new creation: it’s an off-the-shelf smartwatch imported in bulk from its Chinese manufacturer, then given new life with the real star of the show: The Bangle.js firmware.
My work on digital archaeology, meanwhile, was surprisingly bug-free – given I was working to blend modern technology with floppy disks last accessed back in the 1980s. Having been imaging some 3.5″ floppy disks originally used with a Dragon 32 microcomputer, I found myself in need of accessing the raw files within – something loading the disk images into an emulator couldn’t provide.
It’s at this stage I must thank Adrien Destugues, Haiku OS developer, who came to my aid with a port of a tool originally written in 1997 for MS-DOS compatibles by engineer Graham E. Kinns: the Dragon DOS Utils. Using Kinns’ original source code, Destugues was able to port the tools to Linux – giving me what I needed to access the files within the floppy disk images and finish my investigations by loading and decoding a series of saved images into The GIMP.
Finally, Crackers II is – unsurprisingly – the follow-up to Microzeit’s Crackers I: The Gold Rush, coincidentally also reviewed in Issue 218. Picking up where the original left off, the book charts the growth of the software piracy scene on bulletin board systems – along with diversions into the worlds of ASCII art, copy markets, and copy protection systems. As with the earlier book, it’s heavy on the imagery – but there’s plenty of meat in the text too.
