    I didn't get you.. What do you mean by a 'contraption sequence'? Do you need any help in building a contraption or do you want us to share our experience with our contraptions?

    sorry for being unclear.What I meant is we could create a sequence.Like anybody could suggest a conversion of energy.Lets say to start with:we have a stone which using a catapult dislocates a series of dominoes😁

    i want do a contraption
    the aim is to open the window curtain in morning to wake persons
    the 1st operation can be using a alarm and then using a mic to convert sound to electrical
    could u please give me some idea about this one and regarding various energy conversions
    please reply it soon
    as i have to do it by 30th of this month

    How about starting with a sequence.How many steps do you want in?

    Aha, a Rube Goldberg machine. I love these. So we aim to open the curtains? Why not begin with an old fasioned alarm clock that uses a gear actuated hammer to ring two bells? We can attach a cord to the hammer to begin the sequence at the desired time. Perhaps going to Cranky's idea, the cord releases the catapult to set off the dominos.

    I've never had the chance to do a Rube Goldberg machine 😔 Though here's an interesting one done by honda:

    Some parts look a little unbelievable. Can any of you explain how the tires go up the ramp? 😉

    It is a cool video, however I feel some parts are animated. Case in point, the tires going up the ramp!!

    Well, the story goes that it took more than 600 takes to get the sequence right. Not sure if thats true or not!

    Possible explanation of the tire.. something really heavy attached inside the tire at the front, causing it to move forward a little 😛 Plausible?

    Now that you mention it, it does seem possible.

    hi i am a new CE user.i would like to participate in an event called contraption in iit hyderabad(elan).can anyone give me a clear idea of "contraptions".i know that it is a sequence of energy conversions to complete a required task but i would like to know a little more than that.

    Contraption amused me a lot since college daya only where I won first prize at a national level tech fest.

    @ Raja - Idea,
    1. Start with Alarm, use sound to convert sound in electrical and start your computer,
    2. start a song (set it at wnidwos schedular), use voice recognizer to switch on a circuit that is connected to a electrical burner,
    3. Using that flame burn a thread of a pendulam
    4. attach this pendulam with the fan which inturn will be connected to pile of cassets,
    5. drop them on a notebook or hard board (a few pins would be sticked to it)
    6. This board (means pins) will tear a ballon which would e filled with water,
    7. let water drop in a tub which will complete a circuit and in turn that would be connected to a motor
    8. This motor would start a fan a thread attach to a fan
    9. Than fan would open the window curtain.
    Should I make it a bit more lengthy 😀
