fine job. we really need free thinkers

I believe that it could be, but could you use that device and cut out an actual cardboard model so we can see a better profile..... thanks!

Your quite cleaver with the inventions you've come up with. I love the water dripping solar tracker device. No electric motor is needed all natural and gravity is used.

pretty close ncbookz! Just swap your "x" and "a" around and you've got it...
f(x)= ax^2 so your variable is squared instead of your constant :)

DUDE! I thought of that too, after seeing how one can use a string to trace an ellipse! When a distance is constant, a tight string can reproduce it! good job, buddy. the formula is x^2=4px , where p is the distance of the focus from the center point of the parabola. Thumbs up to you

Interesting. I wonder how one makes one of those.

There are many ways. I have another video called "The parts of the mechanical mathematician" that shows a generalized mathematician. You can also check out the vid of the one I used to make my cob parabolic dish. It was made from old junk! The most important thing is you do not have to make an entire dish to have a working reflector

f(x)=xa^2 ? is this the right formula? if not please remove

I actually do not know the formula anymore. It is in 3 Dimension (It traces a dish) so there are x y and z numbers involved, I expect. Thats why I call it the mathematician.
It does pretty hard math.

I hope the other mad scientists will run with this tool and boldly go to new places.

excellant vid this is a nice way to get it done without doing a lot of math and drafting every time you need a parabola

Thanks, I think it could also be done with an existing gate frame swinging on its hinges. You do not need to make a dish. Part of a dish works just as well. (Perhaps better because you can have easy access) Brian
