It’ll be Pi Day when this article goes live, at least for approximately half the globe west of the prime meridian. We always enjoy Pi Day, not least for the …read more Continue reading Hackaday Links: March 14, 2021
New US Electronic Warfare Platform
The Army is developing a new electronic warfare pod capable of being put on drones and on trucks. …the Silent Crow pod is now the leading contender for the flying flagship of the Army’s rebuilt electronic warfare force. Army EW was largely disbanded after the Cold War, except for short-range jammers to shut down remote-controlled roadside bombs. Now it’s being… Continue reading New US Electronic Warfare Platform
Wearable Cone of Silence Protects You from Prying Ears
Careful, the walls have ears. Or more specifically, the smart speaker on the table has ears, as does the phone in your pocket, the fitness band on your wrist, possibly the TV, the fridge, the toaster, and maybe even the toilet. Oh, and your car is listening to you too. …read more

Alarm System Defeated by $2 Wireless Dongle, Nobody Surprised
It seems a bit unfair to pile on a product that has already been roundly criticized for its security vulnerabilities. But when that product is a device that is ostensibly deployed to keep one’s family and belongings safe, it’s plenty fair. And when that device is an alarm system that …read more

The Great Ohio Key Fob Mystery, or “Honey, I Jammed the Neighborhood!”
Hack long enough and hard enough, and it’s a pretty safe bet that you’ll eventually cause unintentional RF emissions. Most of us will likely have our regulatory transgression go unnoticed. But for one unlucky hacker in Ohio, a simple project ended up with a knock at the door by local …read more

Jeremy Hong: Weaponizing the Radio Spectrum
Jeremy Hong knows a secret or two about things you shouldn’t do with radio frequency (RF), but he’s not sharing.
That seems an odd foundation upon which to build one’s 2018 Hackaday Superconference talk, but it’s for good reason. Jeremy knows how to do things like build GPS and radar jammers, which are federal crimes. Even he hasn’t put his knowledge to practical use, having built only devices that never actually emitted any RF.
So what does one talk about when circumspection is the order of the day? As it turns out, quite a lot. Jeremy focused on how the …read more

‘This Is a War’: Prisons Want Cell Phone Jammers to Stop Inmates from Communicating With the Outside World
Prisons want jamming technology to stop criminal activity, but critics warn there would be dire consequences if jamming was allowed to propagate. Continue reading ‘This Is a War’: Prisons Want Cell Phone Jammers to Stop Inmates from Communicating With the Outside World
Freak Out Your Smartphone with Ultrasound
There’s a school of thought that says complexity has an inversely proportional relation to reliability. In other words, the smarter you try to make something, the more likely it is to end up failing for a dumb reason. As a totally random example: you’re trying to write up a post for a popular hacking blog, all the while yelling repeatedly for your Echo Dot to turn on the fan sitting three feet away from you. It’s plugged into a WeMo Smart Plug, so you can’t even reach over and turn it on manually. You just keep repeating the same thing …read more
