I have never understood how this was effective against a determined adversary. An arbitrary limit like 100ml is pointless when there is no limit to the number of times you can pass…

I was left wondering the same. My best guess would be that slope detection could be converting the FM signal into AM. This happens in circuits where the response is strongly depend…

I've been down to McMurdo for a research trip. A couple of things that outsiders find surprising is that most of the people there are support staff and only a small fraction (maybe…

I second this. I picked up one second hand a while back. The placard indicates it was built in 1997. It needed a good cleaning and had clearly seen a lot of use, but is perfectly f…

Seems to work OK for me. I will point out that it is very "coarse" and only has 4 possible settings. Perhaps not the best choice for a slider, but perhaps they made that UI choice …

Very nice project. Much better than dealing with the raw tables/curves from Fair-Rite which seem to have been photocopied again and again over the ages.

Really nice of them to release this. However, unless I'm missing something, the HDL for the FPGA on the Time Card is not part of the release. It looks like it uses a proprietary IP…

I built out a simple "technology access" solution for my late grandma about five years ago. It was just some simple scripts running on a raspberry pi. The scripts would fetch email…

Many modern FPGAs now include dedicated logic for config SRAM "scrubbing." This logic continuously checks config frame checksums to identify upsets. These can then be fixed in real…

If I had to list one thing it would be this: People everywhere, regardless of their race, religion, politics, or wealth are generally decent and primarily interested in making a be…

I left my job when I was in my late 20's to make a year-long round-the-world trip. Leading up to it, I was up for a promotion at work and my managers and colleagues were very skept…

Plane or inclination changes are expensive. Phase changes are cheap, relatively speaking.

Not necessarily. Watermarking an audio stream like this wouldn't require that high of a bit rate. It could easily be hidden "under" the content using coding techniques like direct-…

Interesting because HughesNet as it exists today is serviced with GEO satellites. These can't hit the latency requirements of the RDOF program Only the OneWeb sats at LEO can deliv…

Does anyone know why Hughes, a OneWeb investor, placed and won bids solely within the state of Rhode Island? Is this some sort of squatting play to qualify them for future solicita…

Yes. Guided munitions. Some artillery shells incorporate guidance electronics that survive these sort of conditions.

It is also worth noting that propagation velocity in glass fiber is about 60% slower than free space. Once the constellation is dense enough and OISLs are working, they'll be able …

I'd be surprised if that is the outcome. MIT facilities tends to be quite tolerant of stuff like this.

That is correct. US Citizenship is not a requirement, however, I believe you do need to have a US mailing address.

The MIT Radio Society (W1MX) has gotten their online process up and running and is regularly scheduling sessions. http://w1mx.mit.edu/ham-exams/

PCLATH stands for Program Counter LATch High (byte). In this case latch refers to the digital design technique where you have a register that holds bit(s) until some other event ha…

Not quite what you are describing, but Universal Radio Hacker is a useful tool for reverse engineering protocols. https://github.com/jopohl/urh

Similar story here. I didn't completely tank my GPA due to solar racing (Rose-Hulman, ASC2001) but it certainly didn't do it any favors. None of that mattered though as the practic…

Thanks for this alternative. One suggested edit: Savor should be Sabre
