a ds is a Nintendo product and is very famous.Some of the ds games are Pokemon black,white,white2,black2,mario,Mario Kart, Pokemon diamond,pearl,and platinum Pokemon heart-gold, soul-silver,a bunch of Pokemon Mystery Dungeon,etc.

the improved version is the 3ds a nintendo product and can turn 3ds games to 3D

some are Pokemon x and y(comeing october 3rd),mario kart 7,lego city undercover the chase begins, pilotwing resort,and etc.

What is difference between mAh and volt?

A milliamp-hour (mAh) is a measure of quality of a battery. It tells you how many hours the batter can provide one milliamp of current before it will die. A volt is the unit of electric potential. AA, AAA, C, and D batteries are all 1.5 Volts. A 9 Volt is 9 Volts. Car batteries are 12 Volts. AA's are typically rated in thousands of mAh. Cs and Ds are more, AAA and 9 Volts are typically less. If you know the power that a device consumes [i.e. Remote, wireless game controller], you can calculate how long your batters will last in the following manner. Time = [mAh / 1000] * [# of batteries * battery voltage] / device power Ex: Device is rated at 1W using 4 AA [1.5 Volt] batteries rated at 1000mAh. Time = [ 1000mAh / 1000 ] * [4 * 1.5 Volts] / 1 W = 6 Hours


What resistor will take you from 4.9V to 3.3V?

The nature of your question suggests that you are trying to convert 18VDC down to 3.3VDC Perhaps to power a microprocessor running at that voltage. If you just used a simple divider circuit then there would be two resistors involved, not just one. You cannot "take" 18VDC down to 3.3VDC with a single resistor. You could limit current but not "divide" the voltage down. Really a divider circuit is not the best way to do this either because you probably want to draw at least some current at the 3.3V level. A simple divider circuit voltage would be dependent on the load.. So... I would recommend either a switching or a linear regulator (non switching, and not very efficient). There are a bunch of DC-DC switching regulators that would do the job nicely... I like the ST Micro L5981. It will output up to about an amp at 3.3V and work from 2.9V to 18VDC input. You can find the datasheet athttp://www.st.com/stonline/products/literature/ds/13004.pdfOh, and I'm not pushing the STMicro solution, there are many other good regulators available from Analog Devices, Linear Tech, as well as TI, and National... So Google a bit and you will discover many things for yourself...
