I am trying to find a certain type of heat sink. I am looking for these heat sinks that are closed on four sides with open ends as shown in the picture. Can anybody tell me what these are called or where I can purchase them?
Actually, that's not the point of this project. The point is writing and presenting a proposal. The idea for the product does not need to be mine. It merely needs to be something new and needs to have merit.
Please do not try and lecture me on the details of my project when you don't even...
I have an EE course that requires me to write a product development proposal and right now I am looking for ideas for new products. Are there any new products (EE focused) that you think should be developed or wished existed, but doesn't? Keep in mind that the budget is one million dollars so...
I am taking a senior electrical engineering course in which I and other group members will write and present a research proposal. I am looking for ideas for a research topic and was wondering if anyone knows of good sources to checkout to help find an original research topic. Please note that...
Let the horizontal axis be denoted by (i hat) and the vertical axis be (j hat) and call the function g(n). The function would be something like:
g(n) = sin(n*pi/31)*(i hat) + (sin(2*pi*n/31)+n/10)*(j hat)
If I use a choke ballast rated for 220 volt at 110 volts, will it still work the same? In other words, if the label says 220 volts 400 watts, will it still operate at 400 w from 110 volts or would the output be reduced to 200 watts?
I am trying to find a high voltage transformer with the configuration shown below. The guy that took the picture says that it is an x-ray transformer that he modified slightly, but after all my searching, I can't find a transformer like it. Has anyone seen this type of transformer or know...
I am reading a textbook about communications systems, and just came across a part that I believe to be wrong. As shown below, it says that if you take a vector g = [g(t1) g(t2) ... g(tN)] and take the limit as the number of samples goes to infinity, the result is a continuous function of t...
They are actually not for lighting. I need ballasts to control the amount of current that goes into a variac.
I am using the variac as in input to a high voltage, step-up transformer designed to exceed the dielectric strength of air. Once the arc is established, I need the ballasts to keep...
That's the problem. All I have are these pictures. I am looking for some very robust ballasts with those wattage ratings and I know the ones used in this unit would work perfectly, but I don't know exactly what they are or where they are sold.
I am just hoping someone might recognize that...
I'm looking for a certain type of ballast and was hoping someone could help me find them. I'm looking for the ballasts shown in the pictures. I believe that they are magnetic ballasts. Two of them are 250W, two are 400W, one is 700W, and one is 1000W. Just for scale, the panel in the...
This may seem trivial, but for some reason I am having trouble with it. For a and b in the complex plane, I am trying to prove the following:
|a|^2+|b|^2 >= |(a+b)/2|^2
I need this for part of a larger proof.
In my thermodynamics class, we were shown an equation that gives the work done by expanding pressurized gas given as the integral from v1 to v2 of C/V*dV where C is a constant and v1 and v2 are initial and final volumes respectively. My question has to do with the fact that this is basically...
I just bought a new rigol DG1022 function generator and I noticed that when I turn the voltage higher than 2V peak to peak, the FG emits a faint high pitched sound. It's barely audible; maybe around 15 kHz. Is that normal for a digital function generator, or does that mean that something is...
