Camera microphone

I bought an internet camera with a USB cable, no microphone jack, but it has a built in microphone.
I attached an external microphone to the computer with a banana jack, but the sound is still recorded from the camera microphone.
How to transfer the sound reception from the USB of the camera to the microphone jack?

Drive isn't recognised in Explorer

Sat, 2012-11-24 18:24 by Karol · Forum/category:

I inserted another hard drive into my computer, but connected it through a switch to the power supply.
The drive is connected to the motherborad, just like the main hard drive, which holds the operating system.
This is to prevent viruses, etc', since i intended to switch it on only for backup.
At the beginning it worked even when the computer was on, i mean when i turned the switch on, i saw the backup drive in the browser and could transfer files to it, but now i don't see it anymore, even if i shut down the computer and restart after switching on.

Problem first occured when iTunes was installed, years ago. Sound skips, plays slow and disorted. Spend many hours trying any and all options. Just found this solution and I can now play my music. It was quick and easy. Thanks so much!

RAID at home

Sun, 2011-08-21 09:18 by admin · Forum/category:

This is a report of some experience with RAID 5 in the home.

We started out here with a HighPoint RocketRAID 2300 controller that does part of its work in hardware, but relies for another large part of its duty on an elaborate driver.

The idea is fine and should work much like a pure hardware RAID controller, if only it had the same quality. But there are some obvious problems, like:

  • This kind of controller is not used much in the professional area and therefore gets less scrutiny and testing.

Car navigation by smartphone

Fri, 2011-05-13 18:50 by admin · Forum/category:

So you want to use your phone while driving. Good idea! Smartphones are excellent navigators. Google Maps has by far the most timely and the most accurate traffic information and dynamically routes you around traffic jams. If your time is valuable, you have hardly any choice but to use it.

But first you may stumble over two problems.

1. Where to put it

The three good ways to mount a smartphone in your care are these:

a) A suction cup windshield holder

b) A vent grid holder

c) A glue-to-the-dashboard holder

I recently formatted my Hard Drive & reinstalled Windows XP. Now, when I insert a new CD or DVD disk I'm given false information about the Disk(s). I click on My Computer...right click on Dvd Drive (D;)....Properties. Here's what I see. A blue disk (Drive D:) Used space...0 bytes 0 bytes
Free space...0 bytes 0 bytes.

Why ?
Grateful for any help.

CD/DVDrom wont play DVD Movies

Wed, 2010-09-29 12:14 by Falkland · Forum/category:

I run a LG desktop 153gb Hard Drive with 2gb Ram: OS = WinXP Home SP3.
Initially I had a problem with DMA and PIO, but thanks to your Forum Topic "DMA reverts to PIO"; I followed all the suggestions ( uninstalling primary & secondary channels, running resetdma.vbs and manually deleted datachecksum using REGEDIT and checked Bios); which cured by PIO mode and sound issues. Hard drive is now UDMA5 and the CDROM is now UDMA4.
But when I try to play a DVD movie (Powerdvd10) the program starts but does not respond and just hangs and yet does not drop out of UDMA4 and will not play.

CD dislodged in drive

Mon, 2010-08-09 07:32 by iantheevil · Forum/category:

It seems a CD I was using to install a program somehow came off of the tray and is still inside my DVD drive. The tray ejects fine and I can see the CD in there. It would be tough to get at it but it looks like it might be possible to remove it from the front. I could try putting a blank CD in the drive to see if it would jar the first one loose but I really don't want to aggravate the problem.
