does anybody know a good car video game for xbox 360, wii, or nintendo ds?
i’m not looking for super fast cars, or don’t care even if the cars in the game are similiar to the real cars,
I’m looking for a car video game that has a variaty of vehciles,
I want a video game with Minivans, SUVS, trucks, pickup trucks, busses, ect!
not just the regular sport cars that are in most car video games,
does anyone know a video game like that?
thanks!

Well, Grand Theft Auto has a good variety of cars, but its a little violent. try need for speed ar forza motorsports, they have a few vans and trucks

We’ve got a very small yard of bermuda grass. We’re currently shopping for electric lawn mowers, but don’t know what an acceptable amount of amps would be? We saw one in our price range with 6.5 amps, but for $40 more, we can get a 9 amp mower. Is there a big difference between the two? Would I need more amps? And is it worth the $40 price difference? Thanks so much!

With your very small yard you will not need the higher amp model. You need to keep the grass at a reasonable height each time you mow. In other words do not let it get too long before you mow. That is what will cause a strain on the smaller motor. The difference between the two motors you are looking at is very small. The 6.5 amp is approximately 1/2 horsepower and the 9 amp is approximately 3/4 horsepower. So that is very little difference. I think you should save the 40 bucks for something else.

hi I have a gemini xl 300 turntable and a set of eltax liberty 5+ loudspeakers and I cannot connect the two the RC has a red and a white lead along with a horseshoe shaped metal lead the speakers each have 4 inputs with screwable heads the bottom two on each are labled with + and - I also have four double ended copper wires any help would be much appriciated thanks

What amplifier are you using?

You cannot connect a turntable directly to a pair of speakers - it simply won’t work. You need an amplifier with a phono input (or an off-board phono stage) if you want to hear anything.

I am very interested in car audio and others things like car security etc. Is there a training course in london that specifically makes you become a mobile electronics engineer or something like that? Im not looking for car electricians course but more to do with in car entertainment.

Don’t know about London, but MECP is the certification program here in the states. http://www.mecp.com/home.asp

There’s a jack that the sub-woofer had that went straight into my old tv and the new one has no where to plug in the jack. where do I plug it in? The sub-woofer also has a port to plug in those red and white cables.

You need a receiver to use audio with HD tvs. You plug your speakers and sub into the receiver. There is an optical audio output on the tv where you connect the tv to the receiver. Or buy a receiver which can process HDMI audio and video and just run HDMI from everything into the receiver the one HDMI from the receiver to the tv.

You can’t do things with HD tvs that you did with CRTs.

Is it possible to convert an electric guitar amplifier into a normal output speaker for your computer, iPod, etc, or even a sub-woofer?
If so, would you just need a cable with a 3.5mm jack and a 6.35mm one on the other end?

You could use it as a "normal speaker", but it will sound terrible, so don’t even bother–I mean really awful. Also, the input is a bad match for any output from an audio component. It won’t work at all as a subwoofer. Guitar amps have NO deep bass or even mid-bass output at all!

I need to know the amount of amps each of the receptacles can carry for electric heater purposes. My circuit breaker box says 200 AMPS on the main kill switch, and each of the two rows of switches has tiny numbers on them which don’t seen to indicate how many amps each socket or switch can safely carry. Is there a way to find out? My wall receptacle becomes pretty warm when running 1500 W and I am concerned about fire. Can you help me? Thanks!

Each breaker should have the rating number on them or written in the panel door. 20 for 20amp

My sub woofer is great,but when I crank it up and a song has a lot of bass or in a movie scene and there’s a lot of bass the air port gets kinda loud and it worries me.Any info will help THANKS.

If you’re pushing it that hard then you’re probably going to wear it out quickly. Sounds like you’re pushing it pretty hard into distortion. This is also one of the big problems with ported subwoofers, personally I never use them. The problem is that the air velocity through the port is too high. You’re just trying to get too much air through the port and in order to do this it just has to go too fast. You can stuff the port lightly with Quilt Batting material and possibly improve it some. Otherwise just get a sealed box subwoofer. Porting is a quantity enhancement not a quality enhancement. Go with sealed subs and use more than one. That will get you a lot better bass. Actually open baffle is the best sub, infinite baffle is the 2nd best sub, large sealed box, small sealed box, ported, bandpass is pretty much the order of best to worst bass quality.

In a typical home hi-fi system what is the potential difference across the amplifier terminals that feed a loudspeaker? What is the typical current the loudspeaker wires carry? What is the typical resistance of a loudspeaker?

Loudspeakers are typically 4 or 8 ohm, though there are other impedances.
Note it’s Impedance, not Resistance - as they have a wound coil (effectively an electromagnet), the actual resistance is low at low frequencies and higher at high frequencies.

As an example, assuming an 8 ohm speaker (calculated as a resistance for simplicity) with ten watts RMS power in to it from the amp.

The RMS voltage (think of it as the equivalent DC to give the same power) would be 8.94V
The current would be 1.12 Amps

As the amp signal is AC, the actual voltage & current would be peaking at about 1.4x those figures and dropping to zero at each half cycle.

Power out is ’square law’ ratio to voltage or current, so eg. at 40W RMS, both the voltage and current would be doubled. (Watts are Volts times Amps, so doubling both gives four times the product).

Just wondering if technology has it such that the frequency no longer allows this.

(Two years ago, someone’s cell conversation at my work was heard over the intercom speakers … and there was a lot of cussing going on.)

Nothing is impossible, as your story demonstrates. But even two years ago, that was an extremely freaky set of circumstances that could allow it. Very doubtful that you could re-create that incident using the very same cell phones in the very same locations with the same intercom speakers.
