Gracias sir.

I wasn't sure exactly where I should have posted this but here I go... I was reading that Voltage is a measure of potential energy. With that same mind frame would it be correct to say that PSI is also a measure of potential energy? Specifically referring to the psi in an pneumatic line for...

[FONT="Comic Sans MS"] Spork, at your request, I have posted my questions below. Anyone with insight please feel free to chime in. Also I have now a better understanding of what the term perpetual motion means. At the time when I contacted you I hadn't taken into account that A)the wind is...

You are correct. Many compressor wheels are made in that fashion. I was more concerned with the surface area relative to more blades then the actual amount of them.

I do have a multimeter and soldering iron. Originally I was going to just use an old dimming switch from a junk car and wire it solely to this gauge but I decided to go the route of wiring in a resistor for various reasons. I now know what I need to do though and I thank everyone for their input.

The LED's are soldered onto a pcb board(I'm not sure if that's the proper terminology). Which are inside the gauge. Only way I can easily lower the intensity is to wire up a resistor.

Hey man I really appreciate your input. This is very easy for me to understand. Also I just checked out the Arduino web page and I'm definitely going to give them a shot. Again thanks for the insight. :smile:

I'm not sure I follow you about when you say I wouldn't be able to put 6 volts across a 12volt rated lamp? I used the 2.29amp value because at 24volts that would equal 55watts. So I was seeing wheter or not 55watts is universal or not. Obviously from what you are saying, it is not...but why is...

Also can you please tell me what will happen if say I use a head light bulb that is rated at 12v/55watts and apply it to a 24 volt circuit with only 2.29amps? If it's a 12v bulb I would imagine that it cannot go any higher then that, but seeing as I don't know much about electrical properties...

I do appreciate your insights. Though this is going a little over my head. I hadn't realized that a bulb would have a difference in resistance in relation to temperature. Also I don't know whether or not it's important to note, but the light is a series of LEDs. The particular gauge I have is...

I am trying to get a light in a gauge in my car to become dimmer. How do I go about doing so? I want to keep the voltage at 12 volts but I want to lower the amperage by half. Would I have to by a 2ohm 72watt resistor in order to do this? Also I trying to find some sort of learning kit...

Hello can anyone please provide me with some insight about turbo charger design? Specifically referring to the compressor and turbine blades? My inquiry is more directly aimed at the number of blades. On different turbos they use different numbers of blades and I'm wondering if a higher number...

I am trying to understand a personal dilemma. I would like to hook up an automobile headlight bulb to a custom made battery pack. What I don't understand is how amps are related to the circuit. Let's say I took (2) 6volt lantern batteries and wired them in a parallel circuit. Now that would be...

Anybody?

Also some variables to consider are that air does have mass and therefore has momentum and inertia and that the whole process of the engine sucking in air does take time. I don't know if this adds more difficulty in solving my issue but these are certainly things that must be accounted for. Also...
