Cheap Stuff To Hack: A Router With An SDR For $13

Posted on by

The history of consumer electronics is littered with devices that are relatively uninteresting at first, but become spectacular platforms for hardware exploitation once a few select people figure out how everything ticks. The Linksys WRT54G was just a router until someone figured out how to put a complete Linux system on them. Those RTL-SDR dongles were just for capturing over the air TV until someone realized they were actually a software-defined radio. The CueCat was just dot-com boom marketing garbage until… well, we picked up a lot of CueCats regardless.

Now there’s a new device sitting on the shelves at …read more

Disaster Area Communications With Cloud Gateways

Posted on by

2017, in case you don’t remember, was a terrible year for the Caribbean and Gulf coast. Hurricane Maria tore Puerto Rico apart, Harvey flooded Houston, Irma destroyed the Florida Keys, and we still haven’t heard anything from Saint Martin. There is, obviously, a problem to be solved here, and that problem is communications. Amateur radio only gets you so far, but for their Hackaday Prize entry, [Inventive Prototypes] is building an emergency communication system that anyone can use. It only needs a clear view of the sky, and you can use it to send SMS messages. It’s the PR-Holonet, and …read more

An Ultrasound Driver With Open Source FPGAs

Posted on by

Ultrasound imaging has been around for decades, but Open Source ultrasound has not. While there are a ton of projects out there attempting to create open ultrasound devices, most of this is concentrated on the image-processing side of things, and not the exceptionally difficult problem of pinging a sensor at millions of times a second, listening for the echo, and running that through a very high speed ADC.

For his entry into the Hackaday Prize, [kelu124] is doing just that. He’s building an ultrasound board that’s built around Open Hardware, a fancy Open Source FPGA, and a lot of very …read more

Friday Hack Chat: Making Programming Easier

Posted on by

There is a long history of graphical programming languages. Some people don’t like to code, and for them, graphical programming languages replace semicolons and brackets with easy-to-understand boxes and wires.

This Friday, we’re going to be talking about graphical programming languages with [Boian Mitov]. He’s a software developer, founder of Mitov Software, and the creator of Visuino, a graphical programming language for the embedded domain. He specialized in video, audio, DSP, DAQ, industrial automation, communications, computer vision, artificial intelligence, as well as parallel and distributed computing. [Boian] is the author of the OpenWire open source technology, the IGDI+ open source …read more

Hackaday Links: May 20, 2018

Posted on by

One of the more interesting pieces of tech from Hollywood that never seems to become a reality is a location tracker. Remember the ‘movement tracker’ in Alien that found the cat in the locker? Yeah, like that. Something that reports the direction and distance to a target, kind of like a PKE Meter from Ghostbusters. I think there was something like this in Predator. On Indiegogo, there’s a device that tracks other devices. It’s called the Lynq, and it’s a small, handheld device that tells you the distance and bearing of other paired devices. Hand them out to your …read more

Stretching The Definitions Of A Custom IC

Posted on by

Maker Faire is the nexus for all things new and exciting. At the Bay Area Maker Faire this weekend, zGlue introduced a new platform that stretches the definition of custom ICs. Is this custom silicon? No, not at all. zGlue is a platform allowing anyone to take off-the-shelf ICs and package them into a single module, allowing you to build a smaller PCB with a shorter BOM.

The idea behind zGlue is to take all of the fun chips available today from accelerometers to tiny microcontrollers with integrated wireless and put them on a tiny, tiny board that is then …read more

Video of the Arduino FPGA Board Demo at Maker Faire

Posted on by

This week, Arduino announced a lot of new hardware including an exceptionally interesting FPGA development board aimed at anyone wanting to dip their toes into the seas of VHDL and developing with programmable logic. We think it’s the most interesting bit of hardware Arduino has released since their original dev board, and everyone is wondering what the hardware actually is, and what it can do.

This weekend at Maker Faire Bay Area, Arduino was out giving demos for all their wares, and yes, the Arduino MKR Vidor 4000 was on hand, being shown off in a working demo. We have …read more

Autonomous Agribots For Agriculture

Posted on by

For his Hackaday Prize entry, [TegwynTwmffat] is going all-in on autonomous robotics. No, it’s not a self-driving car with highly advanced features such as cruise control with lane-keeping. This is an autonomous robot that’s capable of driving itself. It’s a robot built for agriculture, and relative to other autonomous robotics projects, this one is huge. It’s the size of a small tractor.

The goal [Tegwyn]’s project is to build a robot capable of roving fields of crops to weed, harvest, and possibly fertilize the land. This is a superset of the autonomous car problem: not only does [Tegwyn] need …read more

Arduino Just Introduced an FPGA Board, Announces Debugging and Better Software

Posted on by

Today ahead of the Bay Area Maker Faire, Arduino has announced a bevy of new boards that bring modern features and modern chips to the Arduino ecosystem.

Most ambitious of these new offerings is a board that combines a fast ARM microcontroller, WiFi, Bluetooth, and an FPGA. All this is wrapped in a package that provides Mini HDMI out and pins for a PCIe-Express slot. They’re calling it the Arduino MKR Vidor 4000.

Bringing an FPGA to the Arduino ecosystem is on the list of the most interesting advances in DIY electronics in recent memory, and there’s a lot to …read more

PGP Vulnerability Pre-announced by Security Researcher

Posted on by

From the gaping maw of the infosec Twitterverse comes horrifying news. PGP is broken. How? We don’t know. When will there be any information on this vulnerability? Tomorrow. It’s the most important infosec story of the week, and it’s only Monday. Of course, this vulnerability already has a name. Everyone else is calling it eFail, but I’m calling it Fear, Uncertainty, and Doubt.

[Sebastian Schinzel] announced on Twitter today he will be announcing a critical vulnerability in PGP/GPG and S/MIME email encryption. This vulnerability may reveal the plaintext of encrypted emails. There are currently no fixes — but there’s no …read more
