Well I want the the LED's to function as bright as possible, without damaging them. So would in series be better than in parallel like I have them now? Also how can I find out what type of resistor I need without using these online calculators? Thank you/

Here is what I have already Powered by a 4.8V battery pack, using 6 Cree XP-G LED's.

I am building a LED array and most of these LED resistor calculators like this one http://led.linear1.org/led.wiz, seem to suggest that I need more than one resistor for the array. From my Calculations I need 1.2 Ohm resistor/s. So my question is given a 6 LED array, why use 6 resistors rather...

Im still a bit confused. So any signal is wave like, so all magnetic fields are wave like? If they are wave like, how does the system tell them apart.

I understand the general aspects of how a hard disk drives works. I have gone deeper and have learned about the various types of magnetoresistance, both AMR and GMR. I understand the fundamentals of how these systems work compared to older units. But people keep telling me that the data...

I have noticed that when one looks at a stopwatch or timer, which counts up or down respectively. if you watch the time being displayed continuously on the clock it seems smooth and uniform. Though if you watch them change, then close your eyes and open them in the middle of the change, the...

I have a minor bit of circuit experience. As a fun project id like to build a shortwave radio. Does anybody have any tips on where to start.

My LA class had a few integrals and derivatives, but that as just for proofs, which we didnt need to know.

I think I've just noticed that I am good with my hands. I like designing Physical system, rather than theoretical computer ones.

A few days ago I interviewed at a financial analysis firm, before I even stepped in the door they made me sign one. so is this one not binding.

I used to be a Computer engineering student and was a bit behind in math, so I went through the majority of my CS course without doing the EE. In 1 more year I will graduate with a CS degree. I don't like the EE stuff to be honest, but like the other more mechanics type engineering. I don't...

So I have been going on a lot of Job interviews, some for big companies. The bigger companies usually make you fill out a disclosure agreement. In the text it usually says something along these lines. It differs from company to company. But I am worried to the true impact of signing these...

Just want to start slow and work my way up. As for math and Physics I've taken Engineering Physics 1-3 and math from calc1-calc 3, Linear algebra and differntial equations.

i like Lays book.

I was to design my own rocket and build it eventually. I am a Computer engineering student and want to go for the other side of engineering. I want to learn all the math and everything. So how an I go about this? Is there some good books? just a general introduction would be great.
