I’ve been studying the deflection of neutrons and isotope types, and believe it could be useful to use massive amounts of waste fuel in a tungsten sphere to split large amounts of deuterium and have it directed at a small source of U to convert it into Pu. What are your thoughts?

Hey, ich bin momentan selbst an meinem eigenen Röntgenprojekt das in den nächsten Tagen abgeschlossen ist. Ich wollte mal fragen welchen Strom die Röhre im Betrieb benötigt ? Was zeigt das eingebaute Amperemeter an ?
@stoppi 9 күн бұрын
Hallo! Ich hatte meinen Röntgenapparat schon sehr lange nicht mehr im Betrieb und kann daher nicht wirklich was zur Stromstärke sagen. Während des Betriebs der röntgenröhre habe ich damals den Strom auch nicht überwacht. Gutes Gelingen und bei Röntgenstrahlen immer sehr vorsichtig vorgehen und genügend mit Blei abschirmen... 😉

Which arduino library did you use for the HX711? I'm using the bogde one and tried to figure out the commands to get it to plot the change in resistance but I'm not seeing any signal in the plotter after I get it started with the button. I verified that the wheatstone bridge is working and I can see a huge change in resistance across the filament when I blow on it, so I suspect it's an arduino command issue. If I could use the same library as you and follow your commands that would be super helpful as a check.

A fluid dynamics analogy to the Lorentz force. Wind being the magnetic field (aether in motion) and the motor being the current that force the magnetic flux to rotate. So the electric motors in this experiment could work because of what is described in this experiment. And why can't we build an electromagnetic equivalent to a wind turbine and extract free energy from a magnet ? 🤔😂 Why do you need a changing magnetic flux ? Does a changing wind from your propeller make your cylinder rotate ?

Hi, your project is good. I have a question: could it be done using only a common LED as a color sensor, since polarizing it in reverse would generate a small current. Obviously it would not be that precise, but it would work. I have put together a colorimeter but using only the webcam and it works pretty well. Now I wanted to see about doing it with a simple LED.
@stoppi Ай бұрын
@@MiguelRodriguez-wn8mc hello! A reverse connected led will work like a photodiode. But I don't know how sensitive it will be compared to a real photodiode and I don't know the spectral response of the led. Maybe if you want to create a whole spectrum with the photometer it won't work with the reversed led. You will have to find it out experimentally. Good luck with your project, cheers stoppi

Beim Titel könnte man im ersten Moment denken, dass Katamarane tatsächlich instabiler wären. Die Grafik bei 4:05 zeigt, dass sie nicht instabiler sind, sondern einfach ein komplexeres Handling haben, wenn man bei Segelboten in höhere Krängungswinkel geht, nehme ich an. Bei einem Motorboot gehe ich nicht davon aus, dass Katamarane oft kentern oder ist es auch da der Fall? Zumindest für die Passagiere ist es vermutlich angenehmer, wenn es sich im Normalbetrieb weniger neigt.
@stoppi Ай бұрын
Hallo! Da haben Sie schon recht. Das Drehmoment ist ja beim Katamaran zu beginn sehr hoch und sollte in den allermeisten Fällen zur Stabilisierung ausreichen. Aber wenn nicht, dann gerät man beim Katamaran durch das abnehmende Drehmoment in eine instabile Lage. Das wollte ich auch experimentell zeigen 😉

Absolutely great project ! Very awesome ! I do wonder how does the gas sensor work ? Does resistance of the filament change in different gas mediums ?
@stoppi Ай бұрын
Hello, thank's. Different gases remove different amounts of heat from the wire. Those gases that remove more heat cause the coil to be slightly colder, which reduces the coil's resistance. The Wheatstone bridge then delivers a different output voltage... 😉
@photonik-luminescence Ай бұрын
@@stoppi pretty neat and simple method ! Absolutely genius ! Also, one last question if you don't mind. Is the distance of the peal from 0 always the same ? If so, we could chart out gases and use this as a method to identify gases. I know that in paper chromatography you divide the length of the traveled solvent and the distance traveled by the test material and get an index. No idea if that index is always constant in a controlled environment. Hey, maybe a cool idea to build would be a Arduino calorimeter. It's not any magic, but maybe a automatic temperature difference monitoring system could be coded onto an Arduino. You could technically do the entire calculation in the Arduino using the "Kalorimetrische Grundgleichung", but again the the use would be a bit questionable.

@@photonik-luminescence the peaks are only then always at the same place, if the circumstances don't change, f.e. The power of the pump...

@@stoppi I very much appreciate your reply. I am looking forward to ways to identify chemicals at home without the use of the way to expensive gas mass spectrometer, so i looked into calorimetry for potentially being able to tell home chemicals apart and maybe gas chromatography for gases like demonstrating CO2 from baking soda with such tools (off course using aqueous calcium hydroxide is quicker and reliable, but who knows if it is always calcium hydroxide...), basically just a second affirmation. I would also try to analyse the compounds that come of a burning candle (wich in theory in a well burning reaction is always water (vapor) and carbon dioxide, so this way i could observe what comes off a candle and demonstrate what compounds are given off when saturated carbohydrate chains burn ideally (without soot). Either way, thankyou very much for reading and going through my comments.
