I wasn't aware of how mass production can substantially reduce prices! Thanks for looking into my question and helping me out.
I'll definitely look into digikey.com.
Thanks!

Compare the cost of even a surface mount resistor when you're buying 1 versus buying 15000. One is probably about 10-15 cents, 15000 is probably about a cent or less, I imagine if you buy a million units its probably a fraction of a cent each.

They might have decided to sell the product at a loss for six months to get a stable userbase and increase marketshare.
Isn't there a local radio shack in your neighbourhood? There's also some online stores like Conrad[^], depending on your location.

You're right. I got my HTC Inspire for $45 at Sams Club, but probably took over $500 to make it.

You're right, this has been the model that many have taken the last ~5-7 years, but usually only on most products that have a service associated with it.

Eddy has it right. They are LOSING money on the phone, but they make it back on the contract you are tied into.
Same with printers and cartridges. How can a printer cost $50 and a cartridge $10?
Anyway, $100 for an electronics kit and tutorials is cheap IMO, espcially if it leads on to you learning something you can sell.

You have a point, but the device I am planning to make would require a Bluetooth adapter, video adapter, etc. That would probably go over $200. Still, I hope to learn something from it.
Thanks!

Even at 200 bucks your education is worth it.
When you are earning that kind of money per day doing embedded code for PC comms devices, you will laugh that you ever thought it expemnsive.

If you want to start with something very basic, Ti has a board for only $4.30[^]. Dunno how far you can get beyond blinking LEDs without having to buy extra parts though....
Edit: ...and even then, the highest end cpu in the series only has 16k flash for your software and 512bytes of ram.

Hi,
I have an mp3 player which I use for the radio in my car (much easier and faster than burning new CDs all the time).
Today, the radio suddenly wouldn't read from the mp3 player at all (it has been an issue all the time, but most of the time it has managed to start playing from it). So I took it inside and plugged it into my laptop, which then started installing the neccessary drivers, which I thought was odd, as it had been plugged in before. Then, when I tried accessing the drive, it said:
F:\ is not accessible. Incorrect funtion.
No matter what I did, I couldn't get access to it. So, I tried plugging it into my other pc (which is running XP), and it said:
The disk in drive F is not formatted. Do you want to format it now?
When clicking Yes, another box appears saying:
There is no disk in drive F. Insert a disk, and then try again.
Is there any hope of rescuing it? If yes, how?
Thanks in advance.

If its an mp3 player, you probably don't want to format it anyway, since you'll probably end up wiping configuration files if not even software that it needs. Time for a new one... 
I've had one do this in the past, just ended up buying another after trying a few things.

Dang. Oh well, it was only 120 DKK (~ $23) anyway 
Thanks.

Considering how they mass produce these things, I'm surprised they even last as long as they do.

This one didn't even last a month before this problem arised. I guess you get what you pay for.
|
|

|

oh... guess that is what you paid for...
...better luck on your next one!

Hi!
I am trying to figure out how the video card talks to a projector. I am trying to code a small device that will be able to display images on the projector. I plan to expand this project, but before I even begin I need to know how I can talk to the projector.
I tried Google, Bing, and CodeProject but couldn't find the answer. I don't necessarily need the code, just a guide, or a paper explaining what happens behind the scenes and what data is exactly sent by the video card.
Thanks!

A video card sends exactly the same signals to a projector as it does to a monitor. It could be VGA/SVGA/XGA/**GA or HDMI or component RGB or just about any other video standard (even composite video  ). A projector, after all, is just a monitor built funny.
Cheers,

OK, here we go:
Preliminar information:
- No UPS sistem mounted.
- Several power cuts.
- Computer that was ON. (yes I know, I know...)
When I try to start up the computer:
The computer can't go further the bios message telling me that I should press F1 to continue as the BIOS has detected some changes (not specified).
If I press F1 nothing happens.
What would you do to recover that computer?
Thank you in advance!

Richard, this looks as an interesting answer. I'll check it when I'll be in front of the computer again.
Thank you for answering!

You were right... after a while it has shown a message telling that the battery had died... after using the bios to set a proper date and time the OS has started again...
|

Try a different keyboard?
If it's getting that far it appears to've POSTed correctly.

ermmm... it is not the same computer I'm using to write those messages... 
Nevertheless I've found what happened... the battery died, the date of the system was resetted and therefore the OS did not started.

I never said it was. This:

Only occurs after the POST is completed.

I've never heard of a system not letting you into the BIOS or an OS boot failing because the battery was dead before.

Me neither... it is amazing: the user told me that nothing happened this morning... after sitting in front of the computer and pressing F1 to continue after a warning telling me that the battery was dead... the Windows loading bar appeared and after that the mouse cursor on a black background. the fact is that nothing else happened... I've restarted a couple of times the computer and the same happened each time... After that, I've entered the bios and set the correct time and date and then all was back to normal... 
Who knows why but it works...
