Another week goes by and another new IoT platform surfaces. Google has announced Android Things, a build of the mobile operating system designed for smart devices rather than the latest slab of mobile eye-candy. The idea is that the same Android tools, framework and APIs that will already be familiar to app developers can be used seamlessly on IoT Things as well as in the user’s palm.
Of course, if this is sounding familiar, it’s because you may have heard something of it before. Last year they announced their Project Brillo IoT platform, and this appears to be the fruit of those efforts.
The IoT-platform market feels rather crowded at times, but it is inevitable that Android Things will gain significant traction because of its tight connections with the rest of the Android world, and its backing by Google. From this OS will no doubt come a rash of devices that will become ubiquitous, and because of its low barrier to entry there is every chance that one or two of them could come from one of you. Good luck!
Retro is new again, and everywhere you look you’ll find films, documentaries, and TV shows cashing in on the nostalgia of their target audience. There is one inaccuracy you’ll find with this these shows: Apple computers are everywhere. This isn’t a historical truth – Commodore was everywhere, the C64 was the computer the nerds actually used, and to this day, the Commodore 64 is still the best-selling computer in history.
Commodore is gone, replaced with a superfund site, but the people who made the best computers in history are still around. At the 2016 Hackaday SuperConference, Bil Herd gave a talk on the second act of Commodore’s three-act tragedy. Bil is a frequent contributor around these parts, and as always he illuminates the 1980s far better than Halt and Catch Fire ever could.
If you were a computer enthusiast in the late 1980s or early 1990s, the chances are that one of your objects of desire would have been a Commodore Amiga. These machines based on the 68000 line of processors and a series of specialized co-processors offered the best compromise between performance and affordability at the time, with multitasking, a GUI, and graphics capabilities that were streets ahead of their competition.
The Amiga story is littered with tales of what might have been, as dismal marketing and lacklustre product refreshes caused it to lurch from owner to owner and eventually fade away from the mainstream in the mid 1990s. But it’s been one of those products that never really died, as a band of enthusiasts have kept a small market for its software and hardware alive.
Earlier this year we showed you a prototype of an unusual graphics card, a modern GPU implemented on an FPGA board that brought up-to-date HDMI monitor support to the Zorro expansion slots found in the big-box Amigas. It’s thus very interesting today to find that the board made it to market, and that you can buy one for your Amiga if you have a spare 189 Euros (now sold out but taking pre-orders for another production run). Producing any niche electronic product is a significant challenge, so it is always positive to see one that makes it.
As well as HDMI output the board features a micro SD card slot that is mountable as an Amiga volume, and an expansion header that is toured as “Hacker friendly”. Best of all though, the whole board is open-source with all resources on a GitHub repository, so as well as reading our coverage of the prototype you can immerse yourself in its internals if that is your thing.
It’s always good to see a new piece of hardware for an old computer see the light of day, though it’s fair to say this development won’t revive the Amiga platform in the way that the Raspberry Pi has for RiscOS. Still, the mere fact of an open-source Zorro FPGA implementation being released should mean that other cards become possible, so we await developments with interest.
[Gerardo Iglesias Galván] decided he wanted to try his hand at bug-bounty hunting — where companies offer to pay hackers for finding vulnerabilities. Usually, this involves getting a device or accessing a device on the network, attacking it as a black box, and finding a way in. [Gerrado] realized that some vendors now supply virtual images of their appliances for testing, so instead of attacking a device on the network, he put the software in a virtual machine and attempted to gain access to the device. Understanding the steps he took can help you shore up your defenses against criminals, who might be after more than just a manufacturer’s debugging bounty.
There is a certain benefit to being an early adopter. If you were around when Unix or MSDOS had a handful of commands, it wasn’t hard to learn. Then you learn new things as they come along. If you started learning Linux or Windows today, there’s a huge number of details you have to tackle. You have the same problem trying to learn CPU design. Grappling with the design of a 16-bit CPU with a straightforward data path is hard enough. Throw in modern superscalar execution, pipelining, multiple levels of microcode, speculative execution, and all the other features modern processors have and you’ll quickly find yourself lost in the details.
[Michai Ramakers] wanted to build an educational CPU and he took a novel approach. The transistor CPU uses only one instruction and operates on one bit at a time. Naturally, this leads to a small data path, which is a good thing if you’re only using discrete transistors. His website is a ground-up tutorial in building and using the tiny computer.
[Victor Frost] has a deep voice and a fancy top of the line camera. While one would assume this to be a more than generous situation for life to put a person in; it’s got its own set of problems. Mainly that his fantastic fancy camera uses the most modern version of the popular h.264 encoding scheme, h.265. Gasp!
While that too seems like a pro, unfortunately h.265 doesn’t play as nice with his editing software. The solution seems easy, just transcode it and get on your way. However, when you start talking about transcoding 4K video from a top-of-the line source and retaining the quality. Well… It can bring a processor to its knees. Since he’d rather be playing overwatch than transcoding video on his main computer, he decided to offload and automate the drudgery to his spare.
That’s how the Ingest-a-Tron 9000 came into play. It uses a lot of open source software and, yes, windows batch files to take the files off his camera, process it on one computer, and dump it to another. Now he can game (or edit) while he waits. For those of us who are estranged from Linux thanks to our favorite software, it’s good to know that there are still ways to automate away the pain. Video after the break.
Tiny laptops have always been devices that promise so much, yet fail somehow to deliver. From the Atari Portfolio palmtops through to the recent crop of netbooks they have been either eye-wateringly expensive if they are any good, or so compromised by their size constraints as to be next-to-useless. We’ve seen DOS, EPOC, Windows, WinCE, Palm OS, Linux distros and more in tiny form factors over the years, yet few have made a significant mark.
The prospect of a “proper” computer in your hand isn’t something to abandon just yet though. We are now reaching the point at which the previous generation of higher-end Android tablets are both acceptably powerful and sufficiently numerous as to be available at a very reasonable price. Perhaps these can provide the tiny laptop seeker with a basis for something useful. [NODE] certainly thinks so, because he’s produced a nice little Ubuntu laptop using a second-hand Nexus 7 tablet and a Bluetooth keyboard case. Android is replaced with an Ubuntu image, and a cardboard cut-out display bezel is held in place with magnetic strips. A step-by-step guide has been put up to help others interested in following the same path.
This is not the most amazing of hardware hacks, in that it involves mostly off-the-shelf items and a piece of software. However it’s worth a look because it does provide a route to a very acceptable little Linux laptop for an extremely reasonable price. One concern is that the Ubuntu version seems not to be a recent one, however we’re sure readers will point at any newer distribution builds in the comments. If you fancy a look at the finished laptop he’s posted a video which we’ve included below the break.
