Beer, Glorious Freaking Beer

In order to bribe, err, encourage more consistent attendance at the DC423 meetings, I am back into monthly homebrews and will be giving them away.  I have 1 liter ez flip cap bottles that I will be filling with my finest, all I ask is:

• You reserve your bottle at:  www.dc423brew.eventbrite.com
• You return the bottle (they are expense)
• You consider making a donation for supplies (not necessary, but appreciated)
• You enjoy your brew and provide honest feedback (help me improve)

Are you a homebrew geek?  Want to learn?  Head over to /make for the recipe and results of the brew.

Enjoy!

RFCat - I Can Haz Megahurtz?

***props again to @tothehilt / all info below is his

The RFCat is a neat piece of kit from atlas 0f d00000000000000m that is a custom flashed Texas Instruments C1111 with python code.  Please reference @at1as information [here]  This USB dongle allows you to play with the sub-GHZ range of RF (think car keyfobs, baby monitors, smart meters, etc)

But enough with the background, how do we get this thing to work?

RFcat Setup:

Plug in RFcat

Make sure your firmware is correct:  

  sudo lsusb

Output should include OpenMoko

  Bus 002 Device 007: ID 1d50:6048 OpenMoko, Inc.

See that on the CC1111 and you are good.
Now unplug dongle, and don't plug in until you get rfcat running.  If you don't you may need to talk to atlas on freenode #rfcat

Complete the rest as follows:

  sudo apt-get install mercurial
  hg clone https://code.google.com/p/rfcat/
  sudo add-apt-repository ppa:pyside #(for specan)
  sudo apt-get update
  apt-get install python-pyside.qtgui #(for specan)
  cd rfcat
  sudo python ./setup.py build
  sudo python ./setup.py install
  rfcat -r

Now plug in your dongle, and enjoy :)
