    28 LED clock

    What exactly do you need help in?  Is it schematics, theory or something similar. Here is a project with a (28) LED clock. Its about mid-way down the page. IMO, this seems like a rather difficult project for a 2nd semester engineering student. I spent my first two semesters doing most of my...

    Engineering Electromagnetics Solution Manual?

    I dont know how the other guys do it. But you can find some books by using a p2p program such as emule. You can also search the bittorrent network. You can search for edonkey/emule files here http://www.filehash.com/edonkey Once you've what you are looking for, open the ed2k link with emule...

    IEEE Potentials. I've only read a few IEEE Pot. in school. Its really good though. http://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=45

    simulation softwares

    Virtual components allow you to set their parameters to any value you like — even if you could not actually find a part with those values in real life. Great for illustrating theoretical concepts.

    High Quality electronic sites

    Not exactly a full electronics site. But I started this site to provide links for students to aid them in studying. Topics include math (algebra - differential equations), physics and some electric circuits tutorials. <link> removed by slackjack

    Ohmfree.com - Electronics Resources

    Great looking site. The best part is that its not tool cluttered with unnecessary stuff. And I also love the wallpaper  :) Good job  8)

    Flip Flops with Multisim

    I think I figured it out. I will have to use a 555 timer to generate the clock pluse. I will also need a POT to adjust the resistance and that would change the frequency of the pluse.

    Flip Flops with Multisim

    Hey guys, I'm trying to design a counter using FF in multisim. I know that I clock signal must come along to for any change to occur in the circuit (I'm forgetting about CLEAR and PRESET for now). What should I use as the souce of the clock in multisim? And another question, what exactly is the...

    Help with IR motion sensor

    Thanks for the link Shahriar. It seems they have integrated the emitter and receiver circuits. All what this circuit does is detect an object as it moves toward it, in this case the car right? If thats so, then this circuit would do just fine for experimental purposes. A vehicle is relatively...

    Help with IR motion sensor

    So without the latch, the output would not remain high when its activated right? What kind of latch do you recommend. Probably a NOR latch?

    Help with IR motion sensor

    I was just asking if its possible. Mayb it would just be easier to build one circuit instead of two...or did I miss something.

    Help with IR motion sensor

    I'm trying to buld this Left = transmitter Right = receiver This circuit has a transmitter and a receiver. So from what I understand, the interruption in a modulated pulsating beam that is transmitted by an infrared diode and received by an infrared transistor sets off the alarm. So what I...

    motion sensor help

    Hello, I need help with building a motion sensor. Nothing fancy, just something simple that I can learn from. If anyone can tell me the parts that I need and how to build it, I would appreciate it. Or you could just point me in the direction of the nearest tutorial, that would be cool. --thank...
