  Dithering in Processing

   » ‎ Hack a Day
  To be honest, we’ve heard of dithering but that’s the extent of our knowledge on the topic. After looking through [Windell's] post about using Dithering in Processing we can now say we’ve got a base of knowledge on the topic. Dithering is used to produce an image out of two colors that our eyes can [...]

  25 GPUs brute force 348 billion hashes per second to crack your passwords

   » ‎ Hack a Day
  It’s our understanding that the video game industry has long been a driving force in new and better graphics processing hardware. But they’re not the only benefactors to these advances. As we’ve heard before, a graphics processing unit is uniquely qualified to process encryption hashes quickly (we’ve seen this with bitcoin mining). This project strings [...]

  [Video] Wideband GSM Sniffing

   » ‎ SecDocs
  Authors: Karsten Nohl Sylvain Munaut
  Tags: GSM sniffer
  Event: Chaos Communication Congress 27th (27C3) 2010
  Abstract: GSM is still the most widely used security technology in the world with a user base of 5 billion and a quickly growing number of critical applications. 26C3's rainbow table attack on GSM's A5/1 encryption convinced many users that GSM calls should be considered unprotected. The network operators, however, have not woken up to the threat yet. Perhaps the new capabilities to be unleashed this year – like wide-band sniffing and real-time signal processing – will wake them up. Now that GSM A5/1 encryption can be cracked in seconds, the complexity of wireless phone snooping moved to signal processing. Since GSM hops over a multitude of channels, a large chunk of radio spectrum needs to be analyzed, for example with USRPs, and decoded before storage or decoding. We demonstrate how this high bandwidth task can be achieved with cheap programmable phones.

  Bluetooth communications for Android devices via Processing

   » ‎ Hack a Day
  [Oscar] shows us how to use a Processing sketch for Android to communicate with Bluetooth devices (translated). It turns out this is easier than you might think. Processing and Android are both closely related to Java, and you can just import the Android libraries that deal with Bluetooth within the Processing sketch. That makes it easy to enable [...]

  Working with I2C port expanders

  There are times when you don’t need much processing power for your project but you do need a lot of I/O pins. It often doesn’t make economic sense to choose a larger microcontroller just to get extra pins so the answer is to use a port expander chip. [Raendra] posted a guide for using one [...]
