  • Thanks, here’s another article about this:

    https://wvutoday.wvu.edu/media-center-blog/2024/09/19/expert-pitch-from-communication-devices-to-deadly-tools-wvu-researcher-elaborates-on-explosive-potential-of-pagers-and-walkie-talkies

    The process of sabotage begins with physical modification of the pager or personal radio. These devices already contain all the essential components for an explosive device: a power source — the battery, a container — the device casing, and a triggering mechanism —the communication circuitry. The addition of a detonator and explosive charge converts them into remote-controlled bombs. A microcontroller is typically embedded within the device to interface with its circuitry, allowing it to detonate in response to external signals.

    “The triggering mechanism for these devices relies primarily on radio frequency signals, as both pagers and walkie-talkies operate on radio frequency bands. In the case of pagers, a unique radio frequency signal can be transmitted over the paging network. The modified pager, programmed to listen for this specific signal, activates the detonator when the correct frequency and signal pattern are detected.

    “Similarly, a walkie-talkie can be set to a predetermined channel and frequency. When the matching radio frequency signal is received, the microcontroller closes the circuit, triggering the explosion.

    “To ensure precise activation, the microcontroller can be programmed to recognize a unique sequence of tones or signal modulations, minimizing the risk of accidental detonation. This setup requires careful pre-programming and maybe signal testing, often involving encryption or authentication sequences to prevent unintended triggering.

    “The combination of radio frequency signals with an embedded microcontroller enables remote activation. It takes a high level of technical expertise to modify these low-tech communication tools into sophisticated remote-controlled weapons.”



  • Anyone else confused about how these bombs are actually detonating? Articles say they are detonating via a text message sent 3x in error, theoretically causing either a spark or a “closed circuit” like a different article explained. The article (from al jazeera) says they have to look at the message but there’s video of one igniting in a bag.

    I’m curious because I think these pagers may actually constitute a public safety risk, similar to how heavily landmined areas risk exploding even decades later on someone unrelated to the initial conflict.

    It is engagement farming for absolutely zero reason.

    So what? Should we ban people posting memes too? Should we ban the engagement system/up vote system? Like what’s your point here? That people share ideas and thoughts? Wow, what news.

    The astronauts in space are a big deal and the latest development had SpaceX rescuing them which is why that person brought it up. They weren’t bringing up Boeing originally, they were bringing up the astronaut story since it all ties together. If SpaceX is grounded, how will they get those astronauts?

    And then the next person points out that Boeing and most CEOs tend to feel like worker deaths are the cost of business. That’s pretty apropos when talking about those astronauts getting stuck up there. Worker solidarity and all.











  • I got IP banned for asking if there was any “good news” about Mitch McConnell after his strokes. I intentionally worded it ambiguously, but the mod on r/politics looked at my political history/not a conservative and decided I was celebrating violence and so I was IP banned. I guess only Mitch McConnell is allowed to salivate at violence openly and the rest of us are supposed to be worried for his health. It’s not a problem if women are the ones he’s directing violence towards, but God forbid a woman speak back to him. Pregnancy and birth cause strokes and clots, and that’s preferable to him vs an abortion… but God forbid he get strokes at the end of his life from being a horrible person and I find that preferable to his stupid harmful policies
