I have several multi-voltage (12/24) power supplies, for phones, PDA etc, and I would like to know what type of circuitry is used to regulate the output voltage. Given that the 24 volt input can vary from 19 to 26volts how does it regulate the output to 5 volts or whatever? How does it determine the input volts in the first place?

I picked up an old fashion 3M overhead projector at an auction. I would like to show some of my old family photos on the wall with it at a family reunion as well as some old childhood drawings on construction paper that are done with crayon. Can you tell me how to run this machine so it shows up on a wall. Thanks!!

I was thinking of using the VGA cable over the compontes cables, but im not sure if i will get a better picture quality out of the VGA. I'm using a Westinghouse LTV-27w7 HDTV, its Native/Optimum Resolution is 1366 x 768. So if i use the VGA cable and set my TV to 720P will i be getting a better picture than using compontes cables.

When I plug in the adapters to my various electronic devices (modems, guitar amps, etc.), both the adapters and the devices are getting hot. This has never happened before. Could this mean that there is faulty electrical wiring at my new apartment? Also, is it safe to keep my devices plugged in?

I have some old vhs home movies I want to copy onto dvds. What is the easiest and perferably least expensive way to do that? Can I make dvd menus and chapters for it? Where can I get it?
PS: I have a very old and slow computer, so count that out.

My cell phone battery isn't holding a charge like it used to. I heard that you can carefully slam it on a hard surface to break up established memory or putting it in the freezer overnight. I'd rather not take the time to charge it all the way and drain it all the way 3-5 times or spend the money on a reconditioner. Any suggestions? Thank you!

I understand that all electrical devices will draw a certain amount of current. For instance a given device that draws .15A at 120v consumes 18W. What I don't get is how to equate this to usage over time. Is that 18W for one second? One hour? One cycle? Certain that this is documented somewhere but I sure can't find it.

Once I know this I can equate this to all the devices in my house and get a better handle on my electricity usage.

I actually don't live in the UK anymore- but I bought mine in Singapore.
Total garbage and a total load of geek and Apple-philiac hype. Lucky where I live- I can trade it in.
I'm buying another Nokia- probably a goldplated N8800 as I have an N95 for business- which is far superior to the Apple- for music and web surfing.

Any experience yet?

I strongly advise you not to waste money on Apple- they are total pants- just like their iPod- a million other far better products out there half the price.

I got confused when trying to buy a flashlight today.
When the flashlight says 3 Watts, is that the same wattage output than a light bulb in my house? 3Watts seems very low to me, yet it was the highest wattage I could find.
How does a lumen compare to a watt?
How does a candlepower compare to watt?
Do volts have anything to do with brightness output? Some flashlights only say how many volts.
Some flashlights only say how many LED's it has, is there any way of telling how bright it is?

How am I supposed to compare if every company uses a different method of measuring light? WHY are there all these different measurements for light now? What was wrong with sticking to watts?

Hi I have a venturer portable dvd player and I hooked up the yellow and white cord thing into the player and my tv. It doesn't show the DVD on it. It just shows the regular channel when I turn the DVD player on. Is there a specific channel or mode my tv needs to be in to view the dvd? The DVD player works fine by itself.

I have a string of lantern lights (essentially christmas lights) and to turn them off, they must be unplugged. I am looking for some kind of on/off switch that will allow me to turn them off without unplugging them. I run other appliances through this separate ports on the extension cord so it is essential that this device only turn off the lights. Where can I find such an item? Does it even exist?

Is there such thing as a coaxial cable entender, that works similar to an ethernet extender (plug the 2 pieces into an electrical wall outlet)?

I am trying to install a satellite dish, but I cannot mount it anywhere outside and that would be close enough to to just run a coax to. If this coax extender exists, I could mount it somewhere farther away, plug it into the outlet, then plug the other end of the extender into the outlet right next to the TV.

I have this idea for a "radio scanner". What this little device will do, is constantly scan the radio stations that are coming in, and let you know which ones come in. Its like a little device that will let you know when a "rock" station (or whatever your choice, ie: oldies, country, etc) is listenable.
For example, your in your car, listening to the oldies and it starts to fade out. You can look down at your device and it will tell you the other oldies stations that are coming in, so you can switch to that one without having to scan. Great for travelers that are not from the area.
Anyways, i have more on this, anybody want to help me?!?

I'm looking for a high-quality portable digital audio recorder in the $100-500 range. I'd like to be able to hook it up to an external microphone and download the audio directly to a computer as an mp3 or wma file. My primary interest is good sound quality with little background noise. Any suggestions are appreciated.
