Meters Pack Led
Does a resistor not effect voltmeter readings?
I'm doing a LED light project for my computer desk and I found a whole bunch of LED's to use, I noticed some of them had a lower voltage rating than 3.2 so I got some resistors and measured the voltage of my AA battery pack with a series of resistors I had, and I realized none of them blocked anything. So I got out a nine volt to see if that might help and again the volt meter showed no difference with a 1k Olm .5 Watt resistor, so does that mean the resistor will have no effect on the power readings or what's going on? I tried 2 of the same type and they did nothing at all to the power readings.
when using a resistor(s) when making up a LED array its purpose is to limit current(amps), not voltage. At a given required LED voltage, the resistor limits the LEDs ability to draw excess current and burn itself out. check out this site to calculate different resistor needs. http://led.linear1.org/1led.wiz

Nice Triband Cell Phone Sony Ericsson K800
Sony Ericsson K800's simple candy-bar form is covered in velvet black coloured casing. The 262k TFT colour screen produces great images and acts as a perfect viewfinder for the powerful camera hidden under the silver lens cover.
Images can be taken in four different resolutions. The camera is equipped with 16x zoom, focus in auto, macro and infinite mode, red-eye correction, camera stabilizer other than special effects, white balance, metering. Ordinary LED flash won't do justice to the camera, so it is fitted with full-fledged impulsive Xenon automatic flash so you can even take decent shot in full darkness. BestPic- an impressive feature that takes four shots immediately before the camera key being pressed and four shots afterwards, so that you can select the perfect frame.
Other features of this 3G phone is equally good. Tri-band GSM and UMTS mobile network support, High speed net access through GPRS/3G, Access NetFront web browser with RSS feed, and remote access through Bluetooth, Infrared and Fast port USB ? The Sony Ericsson K800 is your master key for global connectivity.
Sony Ericsson K800 features one of the strongest camera present in any camera phone. The picture quality and a wide array of imaging features of the phone can be compared with any mid-end digital cameras. Packed with a 3.2 megapixel, Cyber Shot digital camera, made by CMOS-technology, the Sony Ericsson K800 is a decent substitute of your costly digital camera.
Sony Ericsson K800 is a landmark model and is a step forward to change the face of mobile imagining. The difference between K800 and the other Sony Ericsson's Cyber Shot model, K790 is 3G capabilities of the former. Please purchase on online www.phoneandbeyond.com
