Even if you're doing digital design all day you _need_ an analog background to do a good job. Most of the time analog signals aren't directly input to your microcontroller / DSP... as you need to add protection to your input stage, filter for parasites etc... >1Mhz digital signals can't simply be laid out on a board without thinking of the problems that may arise due to the nearby signals / layout of your transmission lines. Everything on your board is analog and I'm not even mentioning what you should take care of when you'll have to do EMC testing. On a side note I'm very skeptical of the article's quality...

Comment: Use mooltipass (Score 5, Interesting) 381

by Mathieu Stephan (#45896183) Attached to: Ask Slashdot: How To Protect Your Passwords From Amnesia?
At Hackaday we're actually developing a solution that could work in your case. The concept behind this product is to minimize the number of ways your passwords can be compromised, while generating and storing long and complex random passwords for the different websites you use daily. It is designed to be as small as possible so it can fit in your pocket. The Mooltipass is composed of one main device and a smartcard. On the device are stored your AES-256 encrypted passwords. The smartcard is a read protected EEPROM that needs a PIN code to unlock its contents (AES-256 key + a few websites credentials). As with your credit card, too many tries will permanently lock the smart card. Therefore, you'd only need to share your PIN code with your husband/wife (5 to 6 numbers) And the whole project is open source....

+ - The Real Story of Hacking Together the Commodore C128->

Submitted by szczys
szczys (3402149) writes "Bil Herd was the designer and hardware lead for the Commodore C128. He reminisces about the herculean effort his team took on in order to bring the hardware to market in just five months. At the time the company had the resources to roll their of silicon (that're right, custom chips!) but this also meant that for three of those five months they didn't actually have the integrated circuits the computer was based on."

+ - Storing your encrypted passwords offline on a dedicated device->

Submitted by Anonymous Coward
An anonymous reader writes "The Hackaday writer Mathieu Stephan (alias limpkin) has just launched a new open source/harware project together with the Hackaday community. The concept behind this product is to minimize the number of ways your passwords can be compromised, while generating long and complex random passwords for the different websites people use daily. It consists of a main device where users' credentials are encrypted, and a PIN locked smartcard containing the encryption key. Simply visit a website and the device will ask for confirmation to enter your credentials when you need to login. All development steps will be documented and all resources available for review."

+ - Easy-phi: an open source rack-based modular platform for hobbyists->

Submitted by Mathieu Stephan
Mathieu Stephan (2892907) writes "The easy-phi team at Université de Genève in Switzerland recently released the specifications for its new open software/hardware platform. The main idea of the easy-phi project is to build a simple, cheap but intelligent open platform consisting of a 19 frame (or smaller), which can house a big variety of electronic modules. Hobbyist would therefore only make/buy the modules that would suit their needs and control them through a web page / standalone application / Labview module. The team is currently looking for partners, so don't hesitate to drop them an email. Additional technical details can also be found on a team's member personal web page ("

+ - Whistled platform gets upgraded for sound recognition->

Submitted by Anonymous Coward
An anonymous reader writes "Few weeks ago, Slashdot featured a cheap platform performing 80FFTs per second to recognize whistles ( The platform is open hardware/open source and is aimed for sound processing projects.
To this goal, the creator [limpkin] just implemented a simple proof of concept algorithm that will control your lighting once the platform listens to a particular word.
A small video has been made to explain the basic concepts of sound recognition to encourage hobbyist to make their own."

+ - Trawling for Tor Hidden Services: Detection, Measurement, Deanonymization->

Submitted by Mathieu Stephan
Mathieu Stephan (2892907) writes "Tor is the most popular volunteer-based anonymity network consisting of over 3000 volunteer-operated relays. Apart from making connections to servers hard to trace to their origin it can also provide receiver privacy for Internet services through a feature called “hidden services”. In this paper we expose aws both in the design and implementation of Tor’s hidden services that allow an attacker to measure the popularity of arbitrary hidden services, take down hidden services and deanonymize hidden services. We give a practical evaluation of our techniques by studying: (1) a recent case of a botnet using Tor hidden services for command and control channels; (2) Silk Road, a hidden service used to sell drugs and other contraband; (3) the hidden service of the DuckDuckGo search engine"

+ - Doing 80FFTs per second to detect whistles to switch on lights-> 2

Submitted by Mathieu Stephan
Mathieu Stephan (2892907) writes "Hello everyone!

Some people told me that my latest project might interest you. I'm not sure you publish this kind of projects, but here it goes.
Basically, it is a small platform that recognizes whistles in order to switch on/off appliances. It will be obviously more useful for lighting applications: just walk in a room, whistle, and everything comes on.
The project is open hardware, and all the details are published on my website.

Please let me know if you have any question,
