This is just the "narrative", isn't it? You can see the same events being given different narratives depending on the race, political persuasion etc of the victim. Nothing at all new here if you're even remotely interested in how event get described in any medium.
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
I saw a 'gator right at the edge of the VAB parking lot last month. In a drainage ditch, up to the fence, cars parked right on the other side.
With luck, they'll start incorporating our radio transceivers. I hear that SpaceX flies with several USRPs now, so that's not completely unrealistic. That might be as close as I can get. Anyone who can get me a base invitation, though, would be greatly appreciated and I'd be happy to do some entertaining speeches while there. I need a base invite for Vandenberg, too. I got in to the official viewing site for the first try of the last launch (and that scrubbed too), but this next one is on Pad 6.
I totally didn't know that! That's awesome!
Here's one I found with four components: http://solomonsmusic.net/FM_Cr...
I am curious how that tiny antenna can produce enough energy to drive even a crystal earpiece. Most crystal radios need huge antennae, don't they? And from the writeup it looks like the FM decoding more or less happens by accident as a side effect of signal interference.
If this really works, I reckon it should be possible to build a miniaturised FM crystal set into a pair of headphones. I wonder if you could do stereo?
I was in Florida to speak at Orlando Hamcation and went to see the DISCOVR launch at Kennedy Space Center. I paid $50 to be at LC-39 for the launch, an observation tower made from a disused gantry on the Nasa Causeway between the pads and the Vehicle Assembly Building. A crawler was parked next door! A hot sandwich buffet, chips, and sodas were served. It was cold and windy! I watched for a few hours and unfortunately the launch scrubbed due to high stratospheric winds.
The next day, Delaware North Corporation, which operates tourism at KSC, decided not to open LC-39 or the Saturn 5 center for the launch. This was the third launch attempt and I guess they decided most people had left. I was annoyed.
The closest beach was going to be closed in the evening, it's a sensitive ecological area. I ended up seeing the launch from Jetty Park. This turned out not to be such a great location, the tower wasn't visible at all and the first 10 seconds of the rocket in flight were obscured before we saw it over a hill.
What's a better viewing location?
...telling us to stay the hell away from their base on Ceres.
We should retaliate by beaming Youtube comments at them.
Apparently it uses 1.5mW at 1V.
You can get batteryless radios. Crystal radios (which don't necessarily contain a crystal) get all their power from the radio signal, and they're scarily simple. During the second world war foxhole radios were built out of a razor blade, a pencil, some wire and a set of headphones (instructions: http://www.bizarrelabs.com/fox...) Prisoner of war radios used coal
AFAIK, however, the much lower energy VHF signals for FM isn't capable of running an FM decoder, and probably not an earpiece either.
I wonder if a modern crystal earpiece could usefully pick up low-power AM transmissions from a cellphone in your pocket without spamming everyone around you with radio waves?
Yeah, sniffing and snorting like animals. Seriously what's that about?
Test equipment is allowed to transmit and receive on those frequencies. If it looks like a radio, it can't. I have a number of cellular testers hanging around here that can act like base stations, mostly because I buy them used as spectrum analyzers and never use the (obsolete) cellular facilities. Government has different rules regarding what it can and can't do in the name of law enforcement, although FCC has been very reluctant to allow them to use cellular jammers.
If you can afford it, something from Ettus would better suit your application.
I left when they ran a "story" about Indian food delivery. Has it improved yet? I see they've not changed the stupid name. For all its faults, I see no reason to drop Slashdot for a site that looks worse than slashbdot did 15 years ago, fewer stories and less than 1000 readers.
If you don't have it, you'll make bad decisions. For example, answer the question, "should I use framework A, or should I write some code myself?" If you can't estimate how long it will take to use the framework and compare it to how long it will take to write the code yourself, then it is impossible to make a realistic decision.
That's a bad example because that's almost never my criteria. I could write my own framework almost as quickly as I could suss out the quirks of someone else's, and that's usually a teensy part of the overall project lifetime anyway. Instead, I judge on things like "do I want to spend the rest of my time here maintaining this thing?" and "who's going to own security updates?" and "will it be easier to hire people with experience on this one or on the one I haven't written yet?". Sometimes there's no good framework A to use, or maybe framework A exists and is popular but is unfit for this specific purpose, so we write something in-house. Either way, notice that "time to get started" is a trivial or nonexistent part of the equation.
I can't read sig-files - the text is superimposed on the line of text below that.
We think after we build this new PCB we can go for the croudfunded manufacturing run. It's mostly surface-mount, and we expect to sell assembled boards in this run, and then the next version will be fully-packaged radios.
