I would eventually want (4) motors moving on the road...but right now I'll settle for one motor turning in the almost friction less air. so for that it would be the initial current required to start the motor which, from the amazon specifications, means it would require 200 mAmps. The angle of...

I am working on building a solar powered toy car for my own edification. The problem I have is that I do not have enough power to start and continue the dc motor(s). I could add a bigger solar panel but I am trying to think of a way that the solar panel could simply collect the energy, store...

Hi, I am trying to build a solar powered toy car. And no its not for my son, its for my own curiosity. The problem I am having is that...while the solar panel is sufficient to rapidly turn the (4) micromotors 6 inches away from a lightbulb it isn't sufficient to even turn the wheels when I put...

Hi I am trying to do a DIY with a servo and I was wondering... If I have a power source (e.g. 4V with 50 mAmps) connected to a 4V servo with a running current requirement of 200 mAmps...where will the current from the power source go? Will it just heat the motor of the servo? Or if there was a...

If I have a power source (4V and 50 mAmps) going into a motor that is 4V with a running current of e.g. 200mAmps. What will happen? e.g. will the current from the power source just heat the motor? Or if I had a capacitor attached to the motor that was e.g. was 4V and 200mAmp...would a charge...

what about "people have been using wood for fire for thousands of years. Just because someone discovers the chemical structure of wood and the process of combustion with oxygen doesn't make the use of wood for fire patent-able.

Hi, I was wondering- how would a normal winged airplane (jet/propeller) stay level as it increased in speed? In other words, increasing the velocity over an airfoil will generate more lift. But what if a pilot just wants to go faster and not higher? Where does that increased upward force from...
