If you've been thinking about playing around with FPGAs and/or are interested in CPU design, [Domipheus] has started a blog post series that you should check out. Normally we'd wait until the whole se...
[Carlos] needed an ADC with a 50 nanosecond sample period for his laser lab, that's 20Msps! (20 million samples a second). While in recent years, commodity ADCs reaching into the low GSPS have become ...
Like many techno-geeks, one of my favourite kitchen appliances is the coffee machine. Mine happens to be a Braun Tassimo T1200, which is by far and away thecoolest coffee machine because it is actually a programmable beverage dispensing system. With it I can make anything from a run-of-the-mill cup of Maxwell House to espresso, latte, cappucino, hot chocolate and everything inbetween. And with almost zero cleanup.
On the path to exploring complex logic, let's discuss the electrical properties that digital logic signals are comprised of. While there are many types of digital signals, here we are talking about ...
Build yourself a buzzing bracelet for subtle haptic feedback as time passes! It's great for reminding yourself to get up and walk away from your desk for a few minutes each hour, or just as a way to have a new awareness of how the perception of passing time varies based on what you're doing.
For their final project for ECE 5760 at Cornell, [Alex], [Sungjoon], and [Rameez] are solving Rubik's Cubes. They're doing it with an FPGA, with homebrew robot arms to twist and turn a rainbow cube i...
earable health monitoring systems integrated into a telemedicine system are novel information technology that will be able to support early detection of abnormal conditions and prevention of its serious consequences. Many patients can benefit from continuous ambulatory monitoring as a part of a diagnostic procedure, optimal maintenance of a chronic condition or during supervised recovery from an acute event or surgical procedure.
PGAs aren’t really programmed, they are configured. Most designers use Verilog or VHDL to describe the desired circuit configuration. Developers typically simulate these configurations before committing them to silicon (a good habit, especially if you ever graduate from FPGAs to ASICs where changes are very expensive). That simulation takes a lot of software you have to install and learn, right?
The Bitcraze Crazyflie 2.0 quadcopter can be controlled by a PC with the Crazyradio USB radio dongle. Unlike the first-gen Crazyflie, this isn't required since the 2.0 works out-of-the-box with Android or iOS as a controller over Bluetooth. However the Crazyradio opens up some fun features like servo absolute position control using Kinect or telemetry from hacked-on sensors. Bitcraze is kind enough to open source their products, giving source, tools, and documentation for the firmware running
ver the last couple of months I’ve been working on an ambitious project – to build a LEGO Mindstorms EV3 machine that can scan an image and then print out a LEGO mosaic of it. Here’s a video of the final model printing out the LEGO logo.
This web page contains an overview of, and Q&A about, our recent results published in a technical paper (PDF, 2.1MB), archived as IACR ePrint 2015/170. It will be presented at the Workshop on Cryptographic Hardware and Embedded Systems (CHES) 2015 in September 2015.
This research was conducted at the Laboratory for Experimental Information Security (LEISec).
Before the days of the RetroPie project, video game clones were all the rage. Early video game systems were relatively easy to duplicate and, as a result, many third-party consoles that could play off...
[Martin] recently purchased a Philips LivingColors lamp. It’s a commercial product that basically acts as mood lighting with the ability to change to many different colors. [Martin] was disappointed with the brightness of his off-the-shelf lamp. Rather than spend a few hundred dollars to purchase more lamps, he decided to modify the onehe already had.
Back in February, Nintendo of America decided to release the *New* Nintendo 3DS following its earlier releases in Europe and Japan. The *New* 3DS is a refresh of the 3DS system, with upgrades such as a quad-core processor, C-stick nub, dual rear triggers (on each side), and face tracking 3D. As with the original 3DS, there are two variants of this system: a pocketable version and a slightly-less pocketable version with larger screens. The smaller model also provides new opportunities in terms of customizability, with removable front and back cover plates that make it possible to change the top and bottom appearance of the console in seconds. There are 59 official cover plates as of writing, and they are pretty neat. The *New* XL, unfortunately, is the same as the old consoles in terms of personalization– there is not much you can do non-destructively besides putting on decals.
