@uscommsnerd It would be expensive to just hand it out... But it would pretty affordable to distribute in other ways, if you catch my drift.

Washington Attorney General Nick Brown filed a lawsuit Friday against Kalshi, an online prediction market platform, alleging it actively circumvents state gambling laws so users can place “prediction wagers” on sports, elections, entertainment awards, and other events. - MyNorthWest

@NWS Hopefully the developer access will be improved as well. Looking forward to it.

Thick smoke is rising into the air as crews work urgently to contain the blaze and prevent it from spreading throughout the building. The incident is unfolding near St. Patrick’s Day parade activity, drawing significant attention as heavy smoke can reportedly be seen from miles away.

The explosion heard across Northeast Ohio was possibly a sonic boom from a meteor breaking up in the atmosphere 😮
NWS Cleveland@NWSCLE

@jacecraftmiller The latest GLM imagery (1301Z) does suggest that the boom was a result of a meteor.

Yosemite Valley is getting pounded by heavy snow this afternoon, with @OpenSnow estimating that 33 inches of snow have fallen in Yosemite Village since Tuesday.

@HackingDave For the drone idea, I did try to design a trailing wire antenna like they do on aircraft for low power. Never went and tested after I added it though. I probably should bust it out again and start building some more.

Nice. Is the antenna actually rotating or is that visual effects? I had mine do the same thing but dropped the visuals for render speed. I planned on a direction antenna at some point but never seen too much of a range gain on directional. At least not enough to justify the build.

Added a new gui to btrpa-scan, sonar effect. Will track and pinpoint based on distance as well as utilize GPS data if you have it. github.com/HackingDave/bt…

@HackingDave If you are playing around with some tech ideas and would like company, let me know where or if so can help. I have a ton of things lying around.

I plugged in what we know about the Nancy Guthrie case and the pacemaker into AI to calculate the probability of finding her within a 120 mile radius. Couple key things we know are true: 1. We can collect much further than the distance of 15-30 ft with signal amplifiers and high gain antennas (best case 800ish ft, but probably more like a few hundred feet). My testing with a 8db omni antenna and a 4000mw transmitter was 813ft for detect a faint signal that recorded in my btrpa-scanner. 2. She has a bluetooth compatible pacemaker which does broadcast at certain intervals (minutes) for a second trying to pair for the phone. This is well documented and well-known from a technological perspective. 3. LE has access to the phone thus having access to the physical address of Nancy's pacemaker. 4. We know drones can be augmented with this tech, using off the shelf stuff at my house I was able to achieve 813ft. 5. Using omni directional antennas to get a wider spread of detection in a 360 degree view vs directionals which are super sensitive to the direction pointing in. You would use directional antennas to pinpoint once a hit on omni's. AI says 85% probability and can rise with more drone coverage. Optimistic for sure, but it's definitely an avenue I hope they are exploring as a viable method to find Nancy. Takes into consideration flight times (40-70 mins on average for commercial drones). Heavy payloads reduce this timeframe but not significantly. A 70 min drone would get 50-55 mins. Area to search: A 120-mile radius circle has an area of A=π×1202≈45,239 A = \pi \times 120^2 \approx 45,239 A=π×1202≈45,239 square miles (a vast region, comparable to covering much of southern Arizona if centered on Tucson).

Iran has floated pausing uranium enrichment for up to three years and sending some of its highly enriched uranium abroad, while seeking sanctions relief. U.S. officials say broad sanctions relief is not being considered – WSJ
