How do you know it's cosmic rays (muons?) and not just background radiation here on earth (eg from radon gas, which accounts for around half the earth's background radiation)?
Having spent a big part my career with video cameras I’m thinking this may be a bit open to discussion. I was working for a Japanese supplier who in the mid 80s began supplying the 1st 2/3” sensor TV broadcast 3 chip CCD cameras over more traditional tube technology. Based in London, we soon discovered if a spare Optical Block (the dicroic prism with all 3 CCD pre-attached) was sent by air, flying over the Nth pole from Japan, pretty much half the pixel of the 3 CCDs would be dead. The picture a camera made looked like the sky on a clear night, so many pixels failed, wrecked by cosmic impulses that were more prevalent at the Poles at high altitudes. My thoughts here though is that the single chip sensor in this little USB camera will likely be a MOSFET device as opposed a CCD. Without seeing its datasheet we don’t know exactly whether it’s a an inter line or frame transfer device or the spec for pixel Noise Floor in zero light. Pixels will all have a different output & under no light with a little gain in a system you can see the mad randomness. Over time certain pixels with higher outputs will become more visible usually related to ambient substrate temperature and parameters like substrate pre-bias voltages. Using a little sensor for a cheap USB camera in this experiment may be more about the performance of the ic device than its ability to detect ie reaction to genuine cosmic particles...
Thanks for sharing your experience. Life on Earth is lucky because we are protected to a large degree from space rays by the atmosphere but not so much as altitude increases. Permanent damage to the CCDs would equate to permanent damage to humans' tissues too, I'd guess. Life is a gamble.
I missed the lower part of your comment. The software has a threshold setting (I used 5) to prevent noise from the CCD being captured as a 'hit'. The makers of the software did extensive testing with different sources of radiation (not only cosmic rays) using the same camera. It was a coincidence that I had one of those cameras so I expect my results are valid due to their extensive testing. Here's is their website: physicsopenlab.org/2016/05/22/misure-con-webcam-particle-detector/
Today i am totaly agree with this comment. Because i did this experiment with the same camera and with faulty power supply of my pc and in the morning i got more dots than our Milky way has. But when i took very good power supply for my PC in the next morning i had only five dots. This experiment i did with other brand of camera result was not trustfull. So cheap camera it is cheap. And i think todays video is only for entertainment one. :)
@@JimsRadioShop NOOOOO! say it ain't so Joe.... I mean Jim . I read somewhere that if I wrap my house w/ chicken wire, it makes a faraday cage. Will that work?
You could duplicate this with a small radiation source (United Nuclear sells a small source, uranium ore sealed in a card) which should work the same as cosmic radiation but faster. Bionerd23 (she left YT 4 years ago) has a video showing how the camera on a phone will pick up particle hits from a radiation source - she put tape over the objective lens and you could see the white dots as they appeared. Harder radiation, the kind you don’t want to be exposed to, will permanently damage the chip in a digital camera.
This reminds me of whistlers on very low frequency. You would probably find this interesting Jim. You can build a vlf receiver quite cheap. Lots of websites have info. Here's one www.backyardastronomy.net/natural-radio-receiver/
I love that you can see something potentially from another galaxy without using any expensive equipment or anything
You can see light from stars. That's from another galaxy. And it's very old.
Really enjoyed this one. What a great, simple idea. Kudos to the developers of the software. Thank you for showing us this.
Wonderful! Thanks. Do you think it would be possible to hook up the detector to an LED lamp that lights up whenever a cosmic ray strikes it?
Can you do an update video about cosmic ray detectors. From my research there seems to be a correlation between cosmic rays and "virus outbreaks".

Да , это основная проблема этого детектора.может быть только герметичная, металлическая, толстостенная емкость поможет избежать помех.

I guess it's a little difficult for me to absolutely prove. I'm experimenting more with it.
link for download?
which software are u using for this?
Привет, это "Theremino"
higgs bosons!! (watch out for creating a black hole with that particle collider ... )
Hey, that's my webcam! Well... was.
JIM! I use aluminum foil hats to deflect the cosmic and. HAARP rays......:D lol happy April
Well your hat doesn't work.

Ask a chicken.

Впринципе подходит любой контрольный источник для проверки радиометро
The obvious question here is why do we need a cosmic ray detector?
To detect cosmic rays.
