Commercial-Off-The-Shelf (COTS) Software-Defined-Radio (SDR) products have been traditionally used for Military RADAR and ...

Yeah, I went with some TrackRs because of the replaceable battery… but Tile now has two models with replaceable batteries.

The release said “smoke and steam were seen coming from the door leading to a transformer vault on the second floor,” and Commonwealth Edison was called to the scene — with a request to expedite their arrival.

As for SunEdison, which rocketed solar into the mainstream before burning up, Brookfield brought it back from bankruptcy after taking controlling interest in its core renewable energy assets for $1.7 billion a year back.

What is the Exif data of picture? • It contains Camera settings, for example, static information such as the camera model and make, and information that varies with each image such as orientation (rotation), aperture, shutter speed, focal length, metering mode, and ISO speed information. • It also includes the GPS ( Global Positioning System) tag for holding location information where the photo was taken.

This sounds impressive, but electric vehicles represent only 1% to 3% of all passenger cars today. “It’s absolutely taking off with high compound annual growth rates, but it comes from a very small base,” said Guy Moxey, senior director of power products at Wolfspeed. “Still, the portion of battery-electric vehicles compared to the overall number of vehicles made is very small.”

Dear Hackaday, this information might be redundant for many of the readers. However it is great info for newbies. This isn’t the first item that falls into this category. I would like to compliment Hackaday with this source of additional easy to read and stimulating educational information, which is spread evenly across the many project related items / posts.

The key feature of this LRC circuit is that it has some natural frequency that depends on the values of L and C. Suppose I do something a little different. What if I connect an oscillating voltage source to this LRC circuit? In that case the maximum current in the circuit depends on the frequency of the oscillating voltage source. When the voltage source is at the same frequency as the LC circuit, you get the largest current.

Ward also points out Tesla coils aren’t very efficient radio transmitters, as they aren’t able to radiate much of the RF energy produced due to the classic situation of poor free-space radiational efficiency that results with an electrically short antenna.

Global Market (Actual Period: 2012-2016, Forecast Period: 2017-2022) • Total Power Transformer Market (By Value, By Capacity) • By Rating (Small, Medium, Large) • By Output Voltage (Step-Down, Step-Up) • By Core Materials (Solid Iron/Steel, Silicon Steel, Amorphous Steel) • By Cooling/Insulation (Dry-Type, Liquid Filled)

Yes, most of what we have known for 60-80 years is still valid, though some new materials help. I think Nylon was what broke open much of radar’s capabilities, which I believe is one of the reasons nylons were so hard to get as depicted in the movies of the day.
