kjennejohn said:Dude, you posted a truncated (the "..." bit) URL and pasting it into the address box would have shown it wasn't going to work. Here's the complete site address, if anyone cares:

You couldn't be bothered to check this yourself and correct it so you foisted it off on us to figure out. I'd like advise and help you but you are obviously clueless and lazy and helping you would eventually end up being a total pain.
The bottom of these threads usually contain four former thread links that relate somehow to the present topic. I've seen four relevant threads at the bottom containing "traffic light" in their titles. I highly recommend you check these out and see how these other school projects ended. You might find exactly what you need.
'Luck on your project!

Point taken on the truncation, but I DID check that it actually brought up a page before posting it.jikes64 said:Thanks again. you should look at the "correct post" you pasted for the url link so u see that it still has the truncated ...... thingy! Its not like I dint paste it correctly!
Anyway I totally understand where ur coming from and I appreciate it. Such Reprimands and sacarsms are what actually put me in check. I hope that someday, I will actually get to where i aspire in life despite the fact that I may not be as privileged as you guys are.
Thanks again.

What normal circuit? Post it so we can help. Do you know anything about your SDK? can you light an LED with it?"If im not able to cross over this hurdle, im gonna have to modify the normal circuit with the timers to somehow incorporate something new."
Wait a second, didn't you say this was a final year project for CORNELL?! That's a privileged education I'd never be able to afford. Then again, I seem to remember doing a cross-walk project for a final year assignment in high school, albeit not a four-way.jikes64 said:I definitely dont have a very privileged education/ tutorin like u guys

1. Hardware design, even of digital circuits, is inherently analog design, albeit not always with the textbook building blocks, but always with the challenges.
2. Good analog engineers generally are self-selected as a pool of guys/gals who like to tinker with hardware.
3. My understanding of the conventional engineering college curriculum is that it has become more and more rarified in the direction of theory and software, not very attractive to these types.
4. High-school science fair participants tend to be hands-on types.
So---What if a university boldly and baldly offers a 3rd & 4th-year curriculum in the fun and headaches of designing and building electronic hardware, built around challenging hands-on projects? And advertises it as such to prospective students? The curriculum would include basic analog (including digital) circuit design, properties of components, lab instrumentation (bought and homemade), sources of degradation, distortion and interference in electronic circuits, plus lab
courses and a design project in each semester. And do bring in industry design and application engineers for an occasional guest lecture.

I think no electronics students should be allowed to graduate until they can show that they can successfully find faults in circuits. This should be a required, practical (Lab) class, with no chance of graduating until the students get an “A”! No simulator tells you exactly where the problem is, no automated tester tells the test engineer what the problem was. Only a breadboard sometimes gives you help by means of smoke signals from the incorrectly hooked up or broken device!
Like fault finding, error analysis is another forgotten science. It used to be done a lot when simulators could not be used to check for every permutation of process variations, supply voltage, temperature, component tolerances, etc

well enough info for anyone who really wants to do the task!blueroomelectronics said:There's not enough info on the site to copy it. Hall effects sensor, little wooden cars with magnets, model traffic lights.
I hadn't interpreted it like that at first, but I see now that you must be right. I can't understand why he insists on following that particular project in light of the suggestions you've provided, some of which might have much more explicit information and no doubt more practical for the equipment he has available to him. What's the criteria for this project? Using an mcu to impress his profs (all power to him, I know how hard it is to make a case in a new area with diehards), and getting it done in a two-month time frame? If that's all I think he should have a little more faith that he can get it done, and just surf till he can find someone who can ship whatever parts he needs to him.blueroomelectronics said:I was not under the impression that was his hardware but a link to a similar project at Cornell.
