Hello, i am a beginner and an electrical college student.
so, i have a project to try Magnetic Direction Finding (MDF) method to lightning location
because natural lightning occurence is hard to predict, my lecturer suggest me to model it into a spark gap from lightning impulse generator.
i have a question
can antenna for ligtning location system can also work to detect signal from a spark gap? or i have to make another antenna because the difference characteristic between lightning and spark gap? thank you! i hope you understand my english.

Piksekiirus ja väljamõeldis |

Olen lihtsalt segaduses pärast seda, kui kohtasin kedagi, kes üritas mulle Enelit (üks tükk) seletada.
Põhimõtteliselt oli idee, et kuna meie poolt välk pärineb tagasitulekust (mis tekitab välgu valguse), peab igaüks, kes reageerib piksenoolile, reageerima tagasituleku kiirusele (1/3 LS).
Mul on inimesi, kes ütlevad, et välgulappe ei saa enamasti tagasitulekuni mõõta, kuid miks see idee vale on?
Kas sellepärast, et tegelik välk pole sama kiirusega kui tagasitõmme?
Kui see nii on, siis miks ei saa lihtsalt öelda, et igaüks, kes reageerib välgule (mida me näeme), reageerib tagasilöögile?192.168.0.1 routerlogin 192.168.l.l

How accurate is my lightning tracker? |

Hi! I’ve been using my lightning tracker to track where lightning is going, I tend to start using the app more or less when there’s lightning in my area, more so since I live In Florida. One thing I’ve noticed is that it’ll tell me that there’s a lightning strike 300 ft from my house.. and I won’t hear anything... so more or less is this app as accurate as people say it is or am I overstating it’s value?
I use the weather channel app too to track rain and lightning as well.usps tracking showbox speed test

Free to loving UK home - two system blue digital filters |

I bought six of the System Blue digital filter chips from Ebay, but used only four of them. LTC1569CS8-7 LTC1569-7 SOP-8.
I offer the remaining two free to a good UK home. (I've nothing against the rest of the world, but I don't fancy fighting customs forms, etc.)
They were stupidly expensive (and not in stock) from normal UK component distributors, but cheap from Hong Kong. The four I've used seem to work.
(Back when I worked for a UK chip manufacturing company, some of our chip batches that failed production test would sometimes turn up in Chinese-made products.)
