Car alternators... Answered

Isnt a car alternator just an electric motor that is acting as a generator? is there anyway to put two old matching ones on a base, attach tires, and power them with a car battery?

Alternative to keyboard

On top is a joystick like an NES joystick. It registers 8 different directions: up, down, left, right, and the in-betweens of those and is controlled by the thumb. Then there are 4 buttons, one for each finger. The joystick replaces the trackpad of a laptop and hopefully is also 'clickable'  to act as a 'left click button. I'm not sure what would do the right click button. Combinations of button presses and joystick directions would replace the keys on a keyboard. I only have the use of my right hand. I initially thought of this as a device for handicapped people like myself, but it would also be good for people lying in bed. The concept maybe could be made into a cell phone case with physical buttons that would allow people to text without looking at their phones. The device is a lot like the nintendo wi remote, but not quite. Maybe a wii remote could be hacked to make a prototype. I wouldn't know how to do that and I wouldn't know how to program it, that's why I'm posting, to see if someone could tell me what kind of skills/knowledge would be needed to make this idea happen. Any suggestions or offers to help are welcome. Thank you!

best way to test an alternator?

We are having some electrical problems with a john deere tractor, and received an error codes 61f, 018, 023, 026, 049, and 051. These error codes are not cleared when the problem goes away, and from memory, the first few meant low fluids at some point, and one of the later ones is indicating the output of the alternator is outside of normal operating range. The problems experienced: * The tractor would start, and "lunge" forward but never actually go any go further than 4 feet. * reverse does absolutely nothing. * hydraulics work fine * Engine would start in any gear, when it should only start in neutral. * Replaced a few dead fuses and a missing relay but these did not change anything important. * oil / hydraulic fluid was very low, we fixed that. * this lunging behavior was intermittent before, only requiring some wiggling of the gear shift. * requires jumping in order to get started. Does not always crank fast enough by itself to start on its own. Today, we plan to test the alternator to see what's going on there, It is rated to deliver 115 charging amps to a huge 12V battery. what is the best way to test this with a basic multimeter or some basic around the house parts? I measured the voltage across the battery rise from 12V up to 14V, so it would seem that it's fine, but I'm going to take that with a grain of rice. Is there a better way to measure the alternator?

Help me reduce my carbon footprint and big fat gut!

So I'm trying to arrange a set up where every morning I pedal my bike, in a training stand, attached to a car alternator, attached to a deep cycle battery which will ultimately be feeding all those computer peripherals that I have scattered across my desk. No exercise, no DSL, etc. (And no, I don't do subsistence farming in my back yard (yet) so I know I'm not really doing much environmentally besides reminding myself how much energy all those littler peripherals suck.) Anyhow, I've seen numerous articles where people are easily getting 12-14 volts out of their alternator. At a level of effort that feels like 20 mph on level ground I'm getting maybe 3v. Any idea what I'm doing wrong?

New ball alternator

Hey I was thinking about having a new ball alternator well at least a idea. I made a model on this knex modeling thing. Well how It SHOULD work is that it is encased in a cage where the ball falls down and a motor will be turning the fan like things. Underneath the fan there might be 1-4 ball path. The fan will move and thus it will make the ball fall randomly in one of the 4 paths. I'm running out of pieces and I don't want to take apart my ball machine that i'm making so you guys can try to make this is you want. It might also be hard to see the yellow rod behind the red one.

Our main source of  energy right now is nuclear energy. Although Nuclear energy  might seem to be a reliable source of energy, it is not.  Nuclear energy is not a reliable source of energy  because you need to extract Uranium ore from the earth's core which might seem as a good  source of Uranium it is not. This is not a endless supply  of uranium because it will eventually  run out of uranium .   So what can we do to solve this issue? The answer is alternative energy.  Alternative energy  is energy that can be renewed  and that is reliable. One solution is replacing Uranium fuel rods in a reactors core with Tritium. Tritium can be used  as a substitute for uranium because it has the same properties as uranium except that it has a shorter  half life.  Tritium is made by fusing solid  Hydrogen With Lithium  in a Farnsworth reactor.  This also has its problems one major  problem is the radiation and heat that is generated during the process  of fusion. Tritium can be then used as a fuel  pellet for a Nuclear reactor when it is mixed with Deuterium which is a solid. Tritium is also a good fuel pellet because it only has a life span of about 12.4 years, then  it decays into Helium 6 which is very harmless. Uranium on the other hand is not  safe because it has a life span of about 2000 years and it gradually decays into other radioactive material such as Thorium, neptunium, ECT.... This is Called the Uranium - Thorium cycle. The tritium is also ecologically friendly because it  can be made from H1 which is found in water H2O.  H1 is called Portion and is extracted through a process called electrolyses in which water is charged by a D.C current.

Alternatives to kite power

I was looking though my old MAKE magazines, and found the schematics for a Kite Aerial Photography rig. For those unfamiliar with the term, it's a camera attached to a kite that allows for aerial photographs to be taken remotely. However, I live in Texas, and the only time the wind blows here is when it rains. And rain means lightning. So, rather than risk electrocution, I'd like to come up with some alternative methods of lift. I was considering a large helium balloon (like a weather balloon), but I was wanting something that I could say I made myself. Then I considered hot air, but I'm not sure how large a homebrewed hot air balloon would have to be to lift a camera. Any suggestions?

alternative to conductive thread.

Ok guys, so i was finishing up a project with my guitar, and i ended up replacing the strings. so i though to myself... what can these be used for. I decided to use them in a project im working on involving a belt, and regular wire would not work well. So, i weaved the guitar string throughout the belt, like you would with conductive thread, and its very very strong, and also flexible. And since its meant to withstand a beating it should last nearly forever. The strings i found to work best are the 3 smallest ones, E B and G, the others are too rigid to bend as much as needed. in the picture that is the third string, so it is more rigid then the first on would be, and i found it to work excellently for what i needed it to.
