Thing is, the bogies (set of wheels) twist, it makes no difference to the engine if the tracks are bent or straight. Jobrag is right, if each car in a train has an engine and each wagon is therefore working, makes things easier, the strain on the links between them is smaller. If on the other...

I know this can't be done, else everyone would be doing it, this question is more of a "why can't it be done? and what are the difficulties that make this impossible?" rather than a "Why is no one doing it?". We have a motor, naturally we would connect it to our mains and draw power, the...

Thanks a lot to everyone, all the answers have been what I was looking for and extremely helpful.

Thank you Mike. Excuse me, one other question. When in college, I remember having to obviously connect the PIC to a computer, this was done through a device that look rounded. While the Atmel and PIC websites offer free programming software, I can't see anything about this piece of kit, how...

Thank you berkeman, that looks like a great help.

I am an Electrical & Electronic Engineering student who has previously used a PIC micro controller for one of my previous college's projects, in that case we didn't have a choice we had to use that particular micro controller, partly because all the class using the same would be easier to teach...

Right, sorted cheers!

Right, I understand Fourier no problem, its the stupid simple integration that is giving me headaches :( if it was \int 1 + sin(nt) then you would get \left[t + \frac{1}{n} cos nt \right] Wouldn't you?

I am studying Fourier for an exam and came across something in my notes that I can't get my head round, might be a simple integration issue. Let me explain. Homework Statement The tutorial question in my notes that I am studying is as following: 1. Consider the periodic function defined...

Thank you for the suggestions. The race car timers actually sounds amazing, as it is the institute supplying the components and all parts to our projects, we have limitations on the pricing and type of components to use. I will have some talks with the teachers and will check to see if I can...

I've got about 8:45 hours of project at my institute per week, I am prepared to spend a few more by myself, also got the whole year until the summer of 2008, don't think time is a problem. I would like to base the project on a PIC microcontroller due to course requirements, this decisions was...

I have to design, test and build a project for my final year of my HND Electrical & Electronic engineering course, and I am unsure of what I will do. I would appreciate any ideas, no matter how difficult or easy they are, these will just be ideas which I might use to adapt into my own...

Thank you. Thank you all, I am surprised at all the replies and really appreciate it. I haven’t follow any of the suggestions here because I have just checked back now and right now I am at work, I will however go back home this evening and take the time to slowly and patiently follow your...

I have a one-year-old PC and it is going as slow as Christmas, and giving me millions of problems. It’s just loaded with stuff and full of crap (Spy-ware, maybe viruses too). I backed all my files on CDs so I can keep them safe and have hardly any memory used on my PC, I tried system restore...

Thank you So, So much. I was along the right lines, but the relationship between the imaginary and real numbers confused me a bit. Starting to make sense and I am starting to get the idea. Thank you.
