Quad Output
What is the best desktop to buy today?

Budget £ 400 – 700, need for Intel Quad, 4 GB RM, HDMI, if possible, sound card optical output. Dell is good …. Studio Slim also is it's better – a digital coaxial or optical cable for sound card amplifier?

I would not buy a Dell, since their support is horrible. They hardly speak English, and have no ownership of problems. The difference between optical and coaxial is not much. Allthough cables Fiber optics have the ability to move more data, we are nowhere near the limit of coaxial. The other terms as the jitter is a load of nonsense. Allthough it is measurable in the digital domain, there buffereing within its receptor that is responsible for that. Coaxial cables are cheaper … BTW, you do not need a luxury coaxial cable if not going over long distances. The cheapest cable patch you have laying around will do well ..

Flat Coaxial
Ok i need help RF/RCA Adapters and/or modulators?

Alright. My little sister got a Coby 19 inch Flat screen tv for christmas. The problem is when we cant connect Coaxial to it. So is there anything out there that does the opposite of a RF Modulator?Where can i buy it? That would be really helpful. and ive tried the old vcr thing. it doesnt work. unless i have the wiring wrong.
so essentially i need something that has this on it.

COAX-IN
COAX-OUT(optional)
RCA-OUT
RCA-IN(again optinal)
it can have more but i need the coax in and rca out.
i looked at the box and it says its a tv. but the problem is i can connect say an antenna in…but if i connect the coaxial cable in. it doesnt work,
The tv does have an antenna in but when i connect the coaxial in it. Nothing shows up and on the dish screen i have it on the right channel and everything but i still cant see it..

With no RF input, your sister got a Monitor NOT a TV.
You need a tuner or a set-top box or a converter.

The VCR should work.

Power Cord
How do I fix one end of my AC cord 2 points of power?

One of the tips broke the AC cord feeding 2 points subwoofer to my face, how do I go about repairing this? The other end of the plug is connected to the subwoofer, ie not is removable. It buily in subwoofer. What should I do?

Change the plug. Make sure the polarity is the same. hot leg has more legs narrow, the neutral carries the widest points. the color will plug replacement screws. Gold is hot and white is neutral.

Power Cord
Can I use the power cord from my old dryer for a new one?

I have an older (probably 1980’s) dryer which I am looking to replace. When I place my order on the Sears website, it asks if I want to purchase a new power cord. Shouldn’t I be able to use the power cord from my old dryer? Or do I really need to buy a new one. I just figure that these sorts of things are universal. Thanks for the help.

Yes it will work just be careful when you have the screws almost out they are real small and if they fall down in the machine it wont be fun getting it out better yet just go buy a magnetic screwdriver takes care of that problem

Dual Polarity

Dual Polarity
DUAL POLARITY power supply?

can someone show me how to make a +/- 12, +/- 5 dual polarity power supply?

I can try to describe it or you can find schematics online.

A lot depends on how much current you want, I’ll guess at 1 amp each. I’d start out with a 12-0-12 VAC transformer. After 4 diodes and 2 big caps, you will have ±16 volts DC. Then use some 3 terminal regulators with heat sinks. Like LM7812 and LM7912.

If you don’t want a lot of current, you can use 5 volt regulators from the same raw ±16 volts, again, on a heat sink, or you use a different transformer, perhaps with about 8-0-8 volts secondary.

Download the data sheets for the 3 terminal regulators, and study them.

Connectors Plug
What Polarities are the Red and White connectors for TV’s?

like the connectors you use to plug in VCR’s, Video Games, sound systems…
i mean like is the inner Point on the plug negative? Or is the outside ring part negative?
Thanks!

For RCA connectors, the pin/hole is the signal and the outside ring is ground.
Generally there’s no true polarity although the pin/hole would correspond to positive and the ground to negative, but if you’re connecting speakers or what not, just be consistent with both so there’s a common ground.

Surge Protector
Can you put a 5300 BTU air conditioning in a surge protector?

My boyfriend just bought a 5.300 BTU room air conditioner. There is no wall outlet near your window and you buy a surge protector with an extension of time to arrive. My question is … Is it safe an AC plug into a surge protector?

Sure you can, provided they do not have a very long extension cord … anything less than 10 meters will be well.

Flat Coaxial
LCD Cable Help …?

Here's my question: I have a 47 "Toshiba flat screen 1080p Lap issued Friday. Right now, I have a TV normal, a digital cable box and DVD player connected to everyone. I'm not getting the HD service for a couple of months, but wants to prove what I can on the new TV before then. Do I have to buy new cables to connect the new TV without using the HD? Should I buy all new cables coaxial for all my other connections (VCR, etc)? I know I will need HDMI, once you select the HD, but I need to know what I get now. Any help is appreciated. Thanks for your help. That last guy with the analogy of the speed boat was in a bad mood, eh? Thanks for being so nice man and patient.

Your new TV probably has a QAM tuner. QAM will screen digital cable TV, including HDTV without a cable box. You should receive at least in local broadcast television stations, including HDTV. Hook-wire directly to the coaxial input on your TV and scan the channels. As for new cables are concerned, The cable company probably hook the HD box with component cables. In general, there is little difference between component cables and HDMI cables. His team the other is SD and can be connected with composite cables or S, and S is preferred. Assuming your DVD player is not a conversion rate up, is also SD. If conversion is upward, then it can not properly issue unless you use HDMI not pay more than $ 20 for an HDMI cable. See link.
