Hackaday Podcast Ep3 – Igloos, Lidar, And The Blinking LED Of RF Hacking

Posted on by

It’s cold outside! So grab a copy of the Hackaday Podcast, and catch up on what you missed this week.

Highlights include a dip into audio processing with sox and FFMPEG, scripting for Gmail, weaving your own carbon fiber tubes, staring into the sharpest color CRT ever, and unlocking the secrets of cheap 433 MHz devices. Plus Elliot talks about his follies in building an igloo while Mike marvels at what’s coming out of passive RFID sensor research.

And what’s that strange noise at the end of the podcast?

Long-Range RFID With Feedback

Posted on by

Not long ago, we published an article about researchers adding sensor data to passive RFID tags, and a comment from a reader turned our heads to a consumer/maker version which anyone can start using right away. If you’re catching up, passive RFID technology is behind the key fobs and stickers which don’t need power, just proximity to the reader’s antenna. This is a much “hackier” version that works with discrete signals instead of analog ones. It will not however require writing a new library and programming new tags from the ground up just for the user to get started, so …read more

Sniffing RFID Readers With A Piece of Paper

Posted on by

We feature plenty of printed projects here on Hackaday, though they tend to be of the three dimensional type thanks to the proliferation of affordable 3D printers. But in this case, [Milosch Meriac] has managed to put together a printable design that’s not only a very cool hack, but is made up of a scant two dimensions. His creation, which could perhaps be considered something of an interactive circuit diagram, allows anyone with a paper printer and a few passive components make a functional low-frequency RFID sniffer.

[Milosch] tells us the goal of the project is to lower the barrier …read more

Meet NFCdrip – a New Security Concern for Air-Gapped Systems

Posted on by

Air-gapping means physically isolating a secure computer from unsecured networks, such as the public Internet or an unsecured local area network. The concept of air-gapping represents just about the maximum protection one network can have from another,… Continue reading Meet NFCdrip – a New Security Concern for Air-Gapped Systems→
