Imagine not letting your kids trick or treat because Halloween is "unholy” and “demonic”, but then you go out and vote for men who touch kids and abuse women…
A developer left a standard Bluetooth Low Energy tracker sitting on a wooden post. It was running on a coin cell, broadcasting a tiny 6-milliwatt pulse (+8 dBm) through a cheap copper PCB trace. Then they drove 13 kilometers (8 miles) down the road.
You would assume Bluetooth has a ten-meter leash. I mean we build smart locks, car digital keys, and proximity badges around the quiet belief that Bluetooth dies at the front door. But radio waves do not understand room boundaries. They leave an antenna and expand across the horizon according to the inverse-square law, diluting into space.
Follow that packet across the countryside. Leaving the tag at 2.44 GHz, the signal loses 122.5 decibels of power by the time it travels 13 kilometers through open air. It arrives on a distant hillside as a microscopic whisper at roughly -115 dBm, buried deep under the thermal hiss of background atmospheric noise. A standard smartphone sitting on that hill is completely deaf to it.
The builder did not touch the transmitter. They left it completely stock and FCC-compliant. Instead, they solved the math on the receiving end.
They hauled a 24 dBi parabolic grid antenna onto a mast and aimed its narrow eight-degree beam directly back at the distant tag. That dish acts like a massive radio funnel, capturing faint wavefronts across its metallic grid and concentrating them into a 24-decibel passive boost.
Then they triggered Bluetooth 5 Coded PHY.
Standard Bluetooth blasts bits at 1 megabit per second, which requires a strong signal to decode before errors corrupt the frame. Coded PHY sacrifices speed for range. It slows throughput down to 125 kilobits per second, using forward error correction to encode every single bit of data across eight separate symbols. That mathematical trade lowers the receiver sensitivity floor down to -104 dBm.
On paper, the link budget gave a comfortable 13-decibel safety margin. Out in the field, the terrain fought back.
Radio energy does not travel in an infinitely thin laser line. Over 13 kilometers, the wave expands into an elliptical cylinder known as the first Fresnel zone, swelling to 20 meters (65 feet) wide at the midpoint. Every hilltop, tree canopy, and barn roof entering that 20-meter zone scattered the wave. Signals reflecting off the dirt arrived slightly out of phase with the direct beam, carving deep cancellation nulls.
Over a thirteen-minute listening window, the receiver caught exactly three intact packets.
Three packets every few minutes is useless for streaming audio or loading a webpage. But for physical surveillance, three packets is total visibility.
Apple Find My, Google Find My Device, Tile trackers, continuous glucose monitors, and car digital key fobs broadcast unsolicited advertisement beacons every second. An attacker sitting on a high-rise balcony or flying a drone with a directional grid antenna does not need to connect to your phone or crack an encryption handshake. They only need to listen.
Bluetooth is thirty-year-old technology, yet modern operating systems still treat its signal as proof of physical proximity. An antenna with passive gain proves that proximity was an illusion all along.
A note to my fellow Republicans:
Choosing Jolly over Donalds doesn't make you a Democrat.
It makes you a Floridian who picked the best candidate.
That's all.
Here it is! Say hello to KONDOR! #ch53K for HMH464 Condors. Buno 170350.
This project had a few challenges mainly translating an Al created design by the sad into paint on the aircraft. But between Dave @s3_viking_nfo and Ray @ray_mendicino we got it on there. I couldn't have done this without Dave and the team of Marines who helped every day.
Not gonna lie there were some doubtful higher ups at first that weren't sure we could pull it off on this multi million dollar awesome helicopter but never fear! 10 days later and voila!
A big thank you to the wonderful hospitality at the squadron for letting us tag your bird. Can't wait to see it fly!
So here's to the first K model color bird, my first K model and by far the ugliest bird I've ever painted.❤️😂
we did it Dave!
Fly high and forever KONDOR! Go Marines! 🇺🇸🇺🇸🇺🇸
For new followers we donate our time to paint mil aircraft.
I heard a pastor in Texas recently tell his congregation “if you vote for Talarico you’re not a Christian.”
If he were my pastor I’d find a new church and vote for @jamestalarico
