Physics project ideas

  1. Nov 15, 2012 #1
    I need to make a project for my school practical exams but I am at a lack of ideas.
    I want to create a project using semiconductor devices and then I have to write a report file on it. Any ideas from your side are appreciated.

    Here's a pdf of the chapter on Semiconductors in my textbook so that you can have an idea of what devices i can use while making the circuit:

    I can use other things too like capacitors and inductors.

    I'd go with the logic devices and build a circuit like a half adder with some AND and OR gates or some kind of simple logic game with LED output.

    You might get some ideas searching on arduino projects although those may involve some programming?

    I will have to see about it although i haven't ever used logic gates except writing truth table for them. :tongue:

    Nope, i am not allowed to use programming. Did you check the pdf i posted? :smile:

    Starting out ...

    This site can help you get more confidence in building circuits - start with the simple ones before going on to more complex experiments. The links are on the left-hand side of the page

    Yes, I scanned your pdf it's rather long to read that's where I noticed the logic gates.

    Another example would be to develop a simple binary LED counter you could tune it to count in seconds or faster.

    Another would be a shift register with LED display where as you press a button and a ONE is propagated thru the register.

    I guess it depends on how complex you want to make and what the goals of your project are.

    Logic gates are nice because you can use truth tables and boolean algebra to design your circuit. They are also simpler to debug than say an amplifier or detector...

    Thanks, those ideas are nice. :smile:
    Do you have any link to pages which have more information about these circuits and the circuit diagrams?

    My circuit don't need to be a complex one, i have to make some simple use of these semiconductor devices and make a simple circuit. I have thought of making a circuit where i can blink the LEDs one by one and i have found some relevant circuits too on the internet.
