Using The Red Pitaya As An SDR

The Red Pitaya is a credit-card sized board that runs Linux, has Ethernet, and a good bit of RAM. This sounds a lot like a Raspberry Pi and BeagleBone Black, but the similarities end there. The Red Pitaya also has two RF inputs, two RF outputs, and a load of digital IOs, all connected to an Xilinx SoC that includes an FPGA. [Pavel] realized the Pitaya had all the components of a software-defined radio, and built an implementation to prove it.

The input for the SDR taps directly into one of the high impedance inputs with a simple loop antenna …read more

End-user training is a noble pursuit but it’s no defense against “low and slow” attacks that take months and years to carry out. We’re all familiar with the infamous quote: Insanity is doing the same thing over and over again and expecting different re…

The Wisest Wizard Doesn’t Drink from Cans

“Wizard Staff” or “Wisest Wizard” is a drinking game played at parties where the attendees participate by taping the empty cans of the drinks they’ve consumed on top of one another to form a staff of inebriated power. A person with a longer staff is considered to be at a higher level and can therefore command lesser wizards to pound their current beverage to a point they see fit. Not everyone at a party necessarily drinks their tasty libation of choice from a can however. So, [Ahmed] and his group came up with a solution for those of us who …read more

Sodium Pickle Lights

A few weeks ago, the folks at the 23b hackerspace held Sparklecon, an event filled with the usual infosec stuff, locks and lockpicking, and hardware. A con, of course, requires some cool demonstrations. They chose to put a pickle in an arc welder, with impressive results.

This build began several years ago when the father of one of 23B’s members pulled off a neat trick for Halloween. With a cut and stripped extension cord, the two leads were plugged into a pickle and connected to mains power. The sodium in the pickle began to glow with a brilliant orange-yellow light, …read more
