Microwave gun detection?

[ryanb9]

If we assume my neighbors are aliens from the future with futuristic microwave guns (just for the sake of argument) sent here to microwave me, is it theoretically possible for me to build a detection machine that could record the levels of radiation, wavelength, etc?

I have a basic understanding of electronics, arduinos, raspis, soldering, etc and I can make some basic things.

Thanks guys. And I'm sorry if I'm making this post wrong or in the wrong place. I'm a newbie here.

Get a RTL-SDR

Holy fuck, not again.

yes you want to make a fast RF peak detector that will trigger if a pulse of microwave energy travels through its antenna, set to trip at a high threshold.

Basically connect a RF power meter with fast response (typically a bolometer) to a threshold circuit that will light up if a high enough intensity EM pulse goes through the broadband receiver antenna.

This sounds familiar to me as well. Was this posted elsewhere?

Don't you know the greys don't use Kardishev zero RF paleo-technology, its just their mind control nanites that make you think they do?

From the guy freaking out at the 100picowatts 400MHz signal?

Sure, set out a bowl of water on the counter.  If it starts boiling then someone is blasting your house with microwaves.

Put two thermometers, one mercury, one alcohol based. If they suddenly start to deviate from each other, you know something's going on.

On a serious note, it's easy to build a wideband detector. You need low capacitance RF diode, a couple of smd resistors, capacitor and multimeter at the output. Add a high pass filter at the input to cut all the lower frequency stuff.

Ahh yes, that was it.

ryanb9, I'm not quite sure where you're going with your posts, but it's starting to sound a little tin-foil-hatty. You mentioned in another thread that you didn't want to disclose details, and that of course is up to you, but consider how an outsider reading your posts might come to the conclusion that something isn't quite right.

Unless you happen to be some kind of high-value or high-profile target to foreign intelligence agencies (in which case you wouldn't be on this forum talking about it), it's entirely doubtful anyone is trying to spy on you, irradiate you with anything or even pay attention to you in any way.

Detecting microwaves has practical uses. Many years ago I was repairing my microwave oven door. Microwave door is quite a precise thing made for shielding. After repair I was adjusting it for minimal leakage, as to not make an interference source. If it's misadjusted, it can leak pretty badly, even disrupting WiFi connectivity.

Aliexpress is full of all types of radiation and Karma protection stickers for your cell phone, maybe you could buy one and slap on your phone to put your mind at ease.

never assume, their is a dead certainty, either you and any one like you, or the wider population are mad. You choose.

Well you will feel the heat directly which would be easily noticed (unless they aim precisely for your eyeballs).  Chronic exposire to broken/poorly sealed microwave ovens has been known to cause eye damage, as the humour in the eye is not directly cooled by blood-flow and warms up over time with modest microwave heating (which you might not feel).

Thanks for sharing your opinion. You have opened my eyes and I've decided to trust you on your word instead of following my own feelings and using science to test reality.

This is a true story. A couple years ago I was talking to a disturbed man in a hospital who was in a lot of pain and under a lot of stress. He was making strange claims that weird things were going on and he was hearing things that disturbed him. His friends and family wouldn't believe him and they decided to call him crazy, which only added to his pain. I told him he should consider getting a microphone and recording what he was hearing, that way he could test weather it was real or not. He looked at me like no one has ever looked at me before, and I think it was because I tried to help him without judging him.

This can absolutely be an easy way to considerately and gently deal with such things in a one on one interaction.

In an online community it's an easy way to become overrun with kooks and conspiracy theorists.

This is 15 years old technology:

(if we assume the video is not a hoax)

What does 15 years of technological advancement backed by billions of dollars via the full force of the USA military machine lead to? They wont tell you. If you want to know what it feels like, come to America and start talking about how fucked up the USA government is in front of your cell phone. You will find out real quick.

these stickers are made from radioactive waste materials and have pretty high radiation level, it is not safe. Just test it with Geiger counter and you will be surprised with very high radiation (up to 1000 times higher than normal level and some of them even more radioactive)...

[Bud]

You don't get it mate, the sticker radiates its radiation 180 degree out of phase of external radiation, therefore effectively cancelling external radiation.
