Cloud chamber construction

[@Nighthawkinlight]

Neat. One of the nicer looking cloud chambers I have seen, and I don't think I've seen one that works with only one layer of peltier coolers.

[@pickle.rickmemes]

Yo!!! cool seeing you here.

[@mattfleming86]

No criticism, just admiration and appreciation. Thanks for sharing!

[@indeathsembrace666]

stunning. excellent work and explanation. bravo!

[@AdvancedTinkering]

Thank you!

[@Haryo-f9h]

Very nice work. What kind of surveymeter that you use to discover this uranium stone? Is it available in the marketplace? Thanks a lot.

[@Ano_Niemand]

nice build man and great job explaining!

[@Gnifl]

Schönes Teil! Total faszinierend

[@40hup]

What is the power consumption (Overwall and for one peltier element) and how long does it take to cool the vapor down to -35°C starting at room temperature?

[@pelos6945]

more details how you use the hight voltage sourse and what mesuars you take to be save

[@handyreiter1310]

This is very impressive. My question is: where does the isopropanol condensate go? shouldnt there be a liquid on the cold plate?

[@gajanan25]

can you show video as how you build from A to Z steps?

[@ChrischiHH]

Tolles Projekt 👍👍👍

[@randomaztec2208]

Very nice . The cooling elements are new to me ..now off to research them a bit. What radionuclide are you using in the chamber. Am241 is commonly found in smoke detectors. it would be interesting to see that placed in the chamber

[@lazymillennialjobseeker9282]

Falling hard into this and other rabbit holes, maybe you can help me from falling further. My understanding of how cloud chambers work is that it’s the supersaturated alcohol that condenses in response to several types of radiation and that’s why you need a temperature gradient, to cool alcohol saturated air that falls from the felt. Is it possible to get this same effect by manipulating the pressure of the saturated air rather than the temperature? Like, say, by using a sufficiently sized alcohol-containing bulb attached to a vacuum chamber? Made from glass joined together by chemically resistant putty? In the shape of a retro reflector? That is coated with two-way mirror film on the outside? Lit inside by those tiny LED balloon lights imbedded in said putty at the corners? Yes, those are the cloud chamber, infinity mirror, and retro reflector concepts taking up space in my attention span at the moment.

[@ivanfranco2363]

Hello! I’d love to get detailed info on how to build this cloud chamber! It’s quite elegant. Is there a website where I can learn how to?

[@IW2MXP]

How many KV did you apply on the high voltage grid? Thank you.

[@BLASTCOMICS999]

how did it get bigger? was that a different specimen?

[@patriksadjak9716]

Eine der schönsten nebeldkammern die ich bisher gesehen habe. Denkst du es wäre möglich das ich die druckpläne haben könnte dammit ich mir auch eine bauen kann ? Bin leider in cad zimlich schlecht Wie viel kv hat die hv versorgung ? Was gibt es dazu zu beachten ? Ac dc, frequenz ??? Vielen Dank und beste grüße

[@mattsmedley.onehandedgamin9029]

Make & model of Geiger counter please.

[@DrunkMouse2030]

Very nice I subscribed

[@mattnottingham3663]

Looks good. Where did you obtain the glass 'bell jar' from?

[@AdvancedTinkering]

Thank you! I bought it on Amazon for around 30 €. If you search for "glass bell jar" you should find it. It is the biggest one I could find.

[@Dormikon01]

Sehr schönes Projekt, Kompliment! Zwei Fragen: Hast Du bei der Bodenplatte bzw. in dem gedruckten Teil eine Rinne o.a. vorgesehen, um ggf. kondensieren Alkohol aufzufangen/abzuleiten? Oder war das kein Problem? Und wenn ich das richtig sehe, ist da keine Heizung für den Alkohol? Es reicht also das reine Verdunsten durch die Raumtemperatur in der Glocke?! Wie lange "läuft" das dann? Schon einmal Danke vorab, ich überlege gerade, eine Nebelkammer aus einer alten Eismaschine zu bauen, da ist ja ein potenter Kältekompressor schon an Bord. Grüße aus dem Ruhrpott! :-)

[@AdvancedTinkering]

Vielen Dank! Nein, die Nebelkammer ist nicht als dauerhaft laufende Nebelkammer gedacht. Nach ungefähr 30 Minuten ist kein Isopropanol mehr auf dem Filz, sondern ist auf der Platte kondensiert. Eine Heizung für den Alkohol braucht man nicht wirklich. Er ist weit genug von der Platte entfernt, um von selbst zu verdunsten. Wenn man eine kleine Rinne mit einer Pumpe einbaut, die den Alkohol wieder auf das Filz transportiert, wäre es möglich, dass man eine Heizung benötigt, da der Alkohol, der von der Platte kommt, sehr kalt ist. Ich hatte dieselbe Idee: Ich wollte mir eine Nebelkammer in einem Couchtisch bauen. Da die Peltier Elemente nur für kleinere Flächen geeignet sind, habe ich mir auch eine Eismaschine gekauft. Das Problem ist, dass man eigentlich nur den Kompressor nutzen kann. Der Verdampfer ist fest in dem „Topf“ verbaut (mit irgendeinem Isolierschaum verklebt). Ich habe es nicht geschafft, die dort unbeschädigt herauszubekommen. Man müsste also das Kältemittel ablassen, einen neuen Verdampfer anbringen und wieder Kältemittel einfüllen. Dazu bin ich bis jetzt nicht gekommen. Falls du es versuchst und Erfolg hast, würde ich mich freuen, von dir zu hören! Grüße!

[@Dormikon01]

Danke für die Infos! Ich dachte an einen anderen Weg, als die ganze Maschine auseinander zu rupfen, denn das da viel verklebt ist, hatte ich befürchtet. Aber im Netz bin ich auf die Idee gestoßen, einfach eine Art Stempel zu bauen: unten eine ca. 10-20 mm dicke runde Platte aus Vollmetall (Alu?) und darauf ein dickwandiges Rohr, das oben wiederum durch die Kälteplatte abgedeckt wird. Das ganze (zumindest an der Bodenplatte) mit Kupfergeflecht umwickelt und in den "Topf" der Eismaschine gedrückt sollte eine hinreichend kraft- und formschlüssige Verbindung ergeben, um schnell genug die Wärme abzuführen. Aus dem vollen Block gedreht wäre da wahrscheinlich noch besser, aber schwer, teuer und vor allem eine so hohe Wärmekapazität, dass man stundenlang vorkühlen müsste. :-) Ich habe einen Nachbarn, der in der Metallbranche arbeitet, den werde ich Mal ansprechen, ob er mir so einen Alu-"Stempel" drehen kann. Wenn denn Mal Zeit wäre ... ;-)

Awesome job. I’m currently also planning on building my own Cloud Chamber and I’m looking forward to watercool it. Now I’m running into some budget issues with a whole custom watercooling loop as a single pump with reservoir costs 150$~ which is too much considering the additional costs of the radiators and fans. Which radiators and pumps did you use, and what was your rough cost of the project? Cheers -Noah

[@AdvancedTinkering]

Thank you! I also thought about using a pump with a reservoir designed for water cooling loops in PCs. But just like you said. They are pretty expensive. The pump I am using is a cheap 10 € Pump for ponds and similar purposes. You should find similar ones on Amazon. I also bought a reservoir from AliExpress for around 10 € but I didn’t use it. Filling the loop without a reservoir is a pain, so I would definitely recommend a reservoir. The radiators are also cheap ones from China. They were around 20 € per radiator. I don’t know the overall cost. I lost track of it. I would guess it was around 300 € with all the changes I made.

[@noahshrktr]

@@AdvancedTinkering Thanks for the reply! I'll do some further research and report on how it went. But i think that this might just make watercooling possible. Thanks!

[@noahshrktr]

​@@AdvancedTinkering Hey there! How high was the HV grid above the coldplate and what was the approximate voltage that was used? Thanks.

[@A5TR31N]

Sehr cool. Was hast du dort auf die Kühlplatte geklebt?

[@AdvancedTinkering]

Wenn du die radioaktive Probe meinst: Americium 241

[@yaykruser]

why is the Radiation not traveling in a straight line?

[@anonyme894]

Hi ! After several prototypes, I ended up following your advice and purchased tec2 25408 elements, they work very well, thanks for the reference!🥰 On my former prototype I got the right high voltage by luck (my voltmeter can't read high voltage). I can't get the high voltage right on my last one: do you have any idea of which voltage you reached please? If you have the reference of your high voltage generator that would be even better !

[@okanarhan2109]

Thanks for sharing. If we want to buy such a setup, what is the price :)

[@AdvancedTinkering]

No problem :) Probably around $ 500 to $ 1000. Building it yourself will be cheaper.

[@TheFanatic155]

Eu não entendo nada sou do Brasil e acho incrível não sei nem como parar aqui mas acredito que é sobre peças de computador e resfriamento ?

[@ShadyTheKing]

Wie oft müsste man den alk fetz befeuchten wenn man es dauerhaft als Design elemente im Wohnraum haben will

[@AdvancedTinkering]

So ungefähr alle 30 Minuten muss man neuen Alkohol zugeben und den kondensierten Alkohol von der Platte entfernen. Das ganze kann man aber auch mit einer Pumpe, die den Alkohol von der Platte wieder noch oben transportiert, automatisieren.

[@garyfoster-adams6911]

Wie hoch ist die Spannung deiner hochspannungsplatte? Kannst du mesons oder muons auch sehen? danke

[@AdvancedTinkering]

Kann ich dir leider nicht genau sagen, da ich einfach den step down converter so eingestellt habe, dass ich die besten Ergebnisse hatte. Myonen und Mesonen sollte ich auch sehen können. Aber ich habe derzeit keine Möglichkeit es zu prüfen, da die Nebelkammer meine einzige Möglichkeit zur Messung diese Teilchen ist.

[@manishaghevade4141]

Is that harmful

[@ggixxler8904]

Tolles design. Kann man dich dazu ein wenig ausfragen? 🤭 Technische Grundlage ist vorhanden, doch wenn strom, hitze und leicht entflammbare stoffe hinzukommen gehen die glöckchen an. 😂

Sehr cooles Projekt, endlich wieder etwas gefunden, was ich nachbauen möchte. Gibt es eine Chance an mehr Details/Baupläne zu kommen?

[@AdvancedTinkering]

Wirkliche Baupläne habe ich nicht. Aber wenn du Fragen hast versuche ich gerne zu helfen!

[@couplingconstant]

Very nice cloud chamber. It seems to work very well. I have a few questions: 1) You mention that there are drawbacks to stacking multiple single stage Peltier elements. What are some of the drawbacks you observed? 2) What voltage do you get from your HV converter? 3) What metal do you use for cold plate and what is its thickness? 4) What water temperature do you get, or how many degrees above the room temperature? 5) What plastic did you use for the 3D printed elements? I am interested in building cloud chambers too. Here is my most recent cloud chamber: kzbin.info/www/bejne/rKDZaqmuhLycmM0

[@AdvancedTinkering]

Thank you! It is not perfect but it works. 1) Since you also have to remove the waste heat from the upper element, you either have to use two different peltier elements or you have to drive the upper element at a lower voltage. Calculating this or finding the sweet spot by trying can be a hassle. And I wanted to use one power supply, so using the TEC2 Elements was the best choice. Since the thermal coupling between the layers of stacked TEC1 elements will be worse, than between the layers in a TEC2 Element, you will lose some cooling efficiency there. Even with a good thermal compound. They also can shift if you don’t use thermal epoxy or bracket. 2) I don’t know the exact voltage. I just adjusted the step-down converter, that drives the HV generator, in until I got the best results. It is pretty low because I got electrostatic effects when the voltage was too high and my vapor layer got disturbed. 3) It is a 3 mm aluminum plate. I am using black self-adhesive foil as a top layer. 4) I never measured the temperature, but I would say it is 30 °C at max. 5) I used PLA. Until now I had no problems with the temperature or the alcohol weakening the PLA. Your chamber looks great! What kind of peltier elements did you use? And how many? What type of alcohol are you using?

[@couplingconstant]

​@@AdvancedTinkering Sorry for the late response. I used TEC1-12706 modules. I basically had them in the same configuration you had, but stacked two TEC1s instead of having a single TEC2, with a total of 8 Peltiers. I used a computer power supply and ran the top Peltiers at 5V and the bottom ones at 12V. I have a 3D printed bracket to prevent them from shifting. Luckily 5V for the top Peltier seems to be very close to the sweet spot, and the 8 Peltiers draw about 300W in the steady state and are able to bring the copper plate down to -35C. I think I initially went with TEC1s because they were cheaper ($3 / piece) than TEC2s, although you have to deal with more cables and thermal paste. I used 91% isopropyl alcohol from CVS.

[@Informative-and-unfortunate]

Great information. Ever since I discovered cloud chambers I've wanted to make one myself that can continuously run without large upkeep. Preferably to sit on the coffee table. EE background so it wouldn't be overly difficult on the electrical and thermal side, but understanding what needed to be done with with the alcohol was the largest unknown.

[@Mrentropy-y6p]

Easy just put uranium on top/cold side of a peltier element 😂

[@gownerjones]

Yeah this totally sucks man. Add some weed stickers.
