    Hey just to point out that if the smoke detector or banna is giving off alpha particles the plexi glass will stop them and it looks thick enough to stop beta particles aswell. not hating actually really cool to see this stuff

    Most new smoke detectors don't have radioactive material and use an optical sensor - just an LED and a photodiode mounted in a way that the LED doesn't shine at the photodiode, but smoke particles can reflect some of the light to it. If you want a radioactive one, it must say so on the box or at least it must say that the sensor works for a certain amount of years and not say it is optical. Radioactive ones are more sensitive but they are expensive and have limited life time. You can get tritium vials that glow for a few years from China for just a few dollars, but I don't know if you can import them to Canada. They are pretty small and virtually harmless- the amount of radiation I got from a 22mm one wit a Geiger counter at the university was about 3 times the background radiation with vial pushed right to the detector. The brightness is similar to a chemical glowstick of the same size that was activated two or three hours ago and green ones appear brightest- the output is the same, but human eyes are most sensitive to green light.

    i just thought of something.....
    if the peltier device always has a set difference in temp between the hot and cold side and you therefore have to cool the heated side in order to get the coldest temps on teh cold side, what if you rigged up somne sort of ducting and a fan or two to pull cold air from the cold side nd blow it over the fins of the heatsink on the hot side? then you have a fully self contained little unit with the best possible outcome (if your desired outcome is the coldest colds)

    That is so freaking cool! Hopefully one day you decide to revisit this invention and beef it up to make it colder and have some kind of radioactive substance to shoot particles in the chamber. Also, really good production overall on the video Mehdi.

    Are you sure your seeing Alpha radiation in that? It's been a while but as far as I can remember Alpha radiation will not penetrate your plastic box, or even the roof of your house? Probably not even the outer atmosphere?
    So I'm pretty sure you are seeing muons (and maybe gamma rays) or other decay products that come about, when cosmic radiation hit's our atmosphere..
    There are also a lot of neutrinos but you won't see them with this setup.
    Like I said though, It was along time ago when I learned about that stuff and I could be wrong.

    That is a one good example of a phenomenon your common person wouldn't have the faintest idea what it is. And the world is full of stuff like that.
    Now think of how many reports there are of ghosts and aliens around the world. There's no way there's a connection there, right?

    Sigh...was expecting you to use an Alpha source of some sort such as Am241 from the smoke detector. The results would have been so much better than normal background. Still a decent setup. Never seen P chips used for this before and good idea with the sponge and resistors.

    Hi There.
    Just to remind you that my parents asked me to buy the electrical socket with negative, positive and ground for its two laundry machines back in India because the washing machine connected with negative and positive poles without the ground and the washing machine conducts its garments with electric shock. I have experienced touching my MacBook Pro charged with negative and positive socket and it feels like a bit of shock so I am wondering if I connect the extension cord with negative, positive and ground to the wall socket I feel nothing while using the computer.
