DIY USB password generator. Having done half a dozen V-USB tutorials I decided it’s time to whip up something cool. As USB keyboards were an area untouched, I decided to make a small USB HID keyboard device that types a password stored in EEPROM every time it’s attached. A new password can be generated just by tabbing CAPS LOCK a few times (4 times to start password regeneration and one tab for each password character generated, 10 is the default password length).
Below you can see the device in action: The place I work at requires me to change my password every few months so this would be one way to skip remembering a new password altogether (as long as I remember to write it down before regenerating a new one so password can be changed :). What is inside? The device is powered with a simplified version of the hardware I used in my ATtiny85 USB tutorial – I stripped away the LCD, reset pullup and both capacitors. The enclosure was graciously donated by an old 512 MB flash drive. Software Update 2: Indiegogo project. GSM Mobile Controlled Robot using 8051 Microcontroller. Quantum Computing: A Primer – Andreessen Horowitz. Watch time: 28 minutes One of the key insights that legendary physicist and Nobel Prize laureate Richard Feynman had was that quantum mechanics (the branch of physics that deals with subatomic particles, uncertainty principle, and many other concepts beyond classic physics) is just way too complicated to simulate using traditional computers.
Nature, of course, can handle these complex calculations — computers however can’t do those same calculations (or would take a prohibitively long time and amount of resources to do so). But this isn’t just about being able to do more with computers in a faster (or smaller) way: It’s about solving problems that we couldn’t solve with traditional computers; it’s about a difference of kind not just degree.
So what is a quantum computer and “qubits” — especially as compared to a traditional computer and bits? What is Grover’s Algorithm?

Google ATAP is bringing touchless interfaces to the market using a miniaturized radar chip no bigger than a dime. This is Project Soli. Google ATAP at Google I/O 2016 Project Soli made a big splash at last month’s Google I/O 2016 conference, even more so than its initial unveiling at Google I/O the year before.
Soli is being developed by Google’s Advanced Technologies and Projects group, or Google ATAP, which tends to focus on mobile hardware technology. Google ATAP differs from its kindred Alphabet sibling, X, in that it incubates projects for only two years where X develops their projects longer, such as their six-year work on self-driving cars. This means that each and every project Google ATAP undertakes is rocketed through development and even production far faster than almost any other incubation process in the world.
The project founder, Ivan Poupyrev, introduced both Project Soli and Project Jacquard (which deals with wearable smart fabrics) at this year's gathering. The Soli Sensor.

On-chip debug (OCD) interfaces can provide chip-level control of a target device and are a primary vector used by engineers, researchers, and hackers to extract program code or data, modify memory contents, or affect device operation on-the-fly. Depending on the complexity of the target device, manually locating available OCD connections can be a difficult and time consuming task, sometimes requiring physical destruction or modification of the device. JTAGulator is an open source hardware tool that assists in identifying OCD connections from test points, vias, or component pads on a target device.

Our two boys, Ben (7) and Miles (3), had become pleasantly obsessed with the coolest brothers in nature – the Kratt Brothers. From the moment that these two energetic animal-loving brothers were discovered by our kids, they’ve been huge fans. Our house has been transported to the Sonora Desert where we saved a Gila Monster, then to the Australian Outback to learn about the Thorny Devil. We even went to swing with the Spider Monkeys in South America and then back to the good ‘ole U.S. of A to harness the speed of the Roadrunner – since we are, after all, a family of runners!
Our boys have been the Grand Brothers for months and there are no signs of it letting up. Turns Out Daddy is an Engineer What can a Daddy really do in this situation? Joe jumped at the chance to help the boys and I jumped at the chance to learn about and document the process. It Starts with a Plan From there, the engineering began. Jtagulator slides.

Antennae design. Sensor Tag. Raspberry. Electronic Boards. Security. Locking the bad guys out with asymmetric encryption. Encryption, the transformation of data into a form that prevents anyone unauthorized from understanding that data, is a fundamental technology that enables online commerce, secure communication, and the protection of confidential information. Encryption algorithms are the mathematical formulae for performing these transformations. You provide an encryption algorithm with a key and the data you want to protect (the plaintext), and it produces an encrypted output (the ciphertext). To read the output, you need to feed the key and the ciphertext into a decryption algorithm (sometimes these are identical to encryption algorithms; other times they are closely related but different). Encryption algorithms are designed so that performing the decryption process is unfeasibly hard without knowing the key. The algorithms can be categorized in many different ways, but perhaps the most fundamental is the distinction between symmetric and asymmetric encryption. c = me (mod n) Decryption is similar:
Semiconductor Engineering .:. The End Is Near. Looking back is easier than looking forward, and looking narrow is easier than looking wide. In 2013, there were several fundamental changes. Change No. 1: IP is now a lucrative market. From Synopsys’ standpoint, it’s been a lucrative market for some time. But the acquisitions made by Cadence, beginning in late 2012, coupled with the push by ARM into the micro-server market and the flailing response by Intel in the micro-server and foundry markets, are just the beginning.
Change No. 2: Moore’s Law increasingly looks like a historical relic (at least for most companies). Change No. 3: The Internet of Things seemed to have sprouted to life in 2013. So what do these changes mean? Prediction No. 1: Third-party IP will become a central part of every design. The big opportunity here, though, is IP that includes both hardware and software that has been tightly integrated for efficiency and performance. Prediction No. 2: Moore’s Law will continue to languish, but not for the obvious reasons. Integration Nation on Planet Analog - Steve Taranovich - GPS: Explaining the Ubiquity of Time.

SDR. Multi-Channel Phase Coherent Vector Signal Generator VSG5000A. This system is comprised of four independent vector signal generators that are able to be phase aligned to one or more of each other, allowing the creation of any complex RF signal environment with any type or mixed types of waveforms. The versatility of the VSG5000A multi-channel phase coherent vector signal generator makes it ideal for several different types of applications. In wireless communications, it can be used to play back waveforms or create new waveforms in order to develop and test satellite and terrestrial voice and data networks. In radar applications, the system can be used to generate multiple signals with adjustable phase relationships to test phased array antennas. It can also be used to play back or recreate complex and dynamic battlefield spectrums for applications involving electronic warfare.
Continuing Education Center - Latest Content. Power Puzzle. September 17, 2013 by Kevin Morris We all learned about power in EE101, right? You know, voltage times current - bam, we're done. Easy as Ohm's Law. Of course that was just for DC, and we had to learn how to do all that RMS stuff for signals that wiggle. Still, we left engineering school having a pretty good feeling that we had this whole power thing under control. Fast forward a few years and we're in industry, designing digital circuits. We applied those lessons to do things like gating our clocks, making circuits wider and lower-frequency instead of narrower and higher-frequency, sizing our transistors to be appropriate for the job they have to do, and minimizing IO activity and memory accesses. Then, we got our first FPGA. Fortunately again, the FPGA company gave us a nice spreadsheet thingy that would give us an estimate of our design's power consumption - accurate to within just three or four orders of magnitude.
Now, a word of warning is appropriate here. Let's be clear here. Cp.literature.agilent.com/litweb/pdf/5990-8507EN.pdf. File Input and Output using XML and YAML files — OpenCV 2.4.6.0 documentation.
