The Achilles heel of today's surveillance cameras was that they had to be supplied with power via one cable and the signal via another cable. So far, this has limited the possible locations of surveillance cameras, as well as where bugs can be set up with video feed. The hunger for power from video encoding and network stuff is one of the more important lines of defense against even more blatant total surveillance. Now these lines have been broken ...

The University of Washington is currently researching in both areas and is trying to find out whether one can Camera without the power-hungry parts and then whether it is not possible this connect passively powered IoT devices to the network. These devices require so little power that it is enough to pick up RF signals in the area. The device class previously had no network access because you need an antenna for it and it has to be supplied with power. But as it turns out, narrowband communication with regular WLAN infrastructure (1 kbps over 2,1 m distance) can also be made with passively powered devices. Of course, this opens up completely new areas of application and so the next generation of bugs will probably be really bad. Brave New World ...

"Dravens Tales from the Crypt" has been enchanting for over 15 years with a tasteless mixture of humor, serious journalism - for current events and unbalanced reporting in the press politics - and zombies, garnished with lots of art, entertainment and punk rock. Draven has turned his hobby into a popular brand that cannot be classified.

My blog was never designed to spread news, let alone get political, but with current affairs I just can't help but capture information here that is otherwise censored on all other channels. I am aware that the design page may not seem "serious" to many in this regard, but I will not change this to please the "mainstream". Anyone who is open to non-state-compliant information sees the content and not the packaging. I've tried enough to provide people with information over the last 2 years, but quickly noticed that it never matters how it's "packaged", but what the other person's attitude towards it is. I don't want to put honey on anyone's mouth to meet expectations in any way, so I'll keep this design because hopefully at some point I'll be able to stop making these political statements, because it's not my goal to go on like this forever ;) I leave it up to everyone how they deal with it. However, you are welcome to simply copy and distribute the content, my blog has always been under the WTFPL license.

It's hard for me to describe what I'm actually doing here, DravensTales has become a culture blog, music blog, shock blog, tech blog, horror blog, fun blog, a blog about found items on the internet, internet bizarre, trash blog, art blog, water heater, zeitgeist blog over the years , Scrap blog and grab bag blog called. Everything that is right ... - and yet not. The main focus of the blog is contemporary art, in the broadest sense of the word.
