i need an idea for a simple machine project?

oh man i remember those... i loved those. I got first at state.\n\nMy plans were:\n\ncut a rope\ndrops a weight\nmoves a lever\nmoves another lever\ncar goes down the lever\nhits a pillar\npillar falls down\nball drops off of platform on pillar\nrope attached to ball spins a fan\n\nfan is attached to another string that winds a platform \nupwards\n\nplatform hits a switch\nswitch sets a pendulum in motion\npendulum hits a cup of beans\nbeans fall and land on a mousetrap\n\nmousetrap has a piece of metal on it that flips the page in\na book\n\nMouse trap also pulls a piece of string with metal attached to it.\n\nmetal was holding back a ball\nball falls down a bunch of gutters\nball reaches end of gutters, goes thru Ubend pipe\nball hits another pillar with a screw in it\nscrew pops baloon\nsequence done.\n\nIt took my contraption about 20 seconds to complete and was 3'x3'

If you get two cotton reels and string one to a weight and ine to, say, the top of the desk, then you can put diferent amounts of loops of string round each on and make a simple pulley.\n\nTo do levers all you need is a screvdriver and a pot of paint thatv you can't open. Ask your teacher to try and open the paint. when he cant, take the screwdriver and put it under the lid and prize it off. this is a lever because it makes the work required smaller but the distance greater.

Perhaps the illustrated link and description will help you.  Good luck with your project.

You could do this in a MS Word document by typing the instructions and supplementing them with hyperlinks to where files are stored and to the useful websites.\n\nIf you are looking for specific software there is a huge range to consider. You might want to look at ones focused on GTD (Getting Things Done) - see below - but the learning curve for any specialised product is going to be substantial. Do you have that sort of time?\n\n///

The best project would be one that interacts with the people. Maybe a USB camera connected to a computer and voice output. The camera might read the number of fingers a person holds up then says "three". Hardware and software both, plus fun interaction is always a winner!\nMIKE

Well it is pretty easy to build a simple motor. There are instructions at this website.

Yes, you need a lab to do this! If that wasn't clear to you, this may not be the best project to try to copy!\n\nWhy not have an idea of you own, something you can do with what you have at hand at home? You might learn something!

Go to http://www.elance.com and post your project. I get all of my web programming done there.

hmmm..... media player? boohh......\ndns server? boooh....\nit's so lame.\n\nif you want to find a 'bunch' of inspiration for your project, goto this site\nhttp://sourceforge.net/\n\nbtw, if you have decide what program you want to build, post it in your comment later.

What might be an interesting project is making a simple 'projector' with a magnifying glass, perhaps for showing film strips or images drawn on cut pieces of transparency sheet fed into the 'projector'.\n\nYou could opt to use a posterboard as a screen, or calculate how far away from the wall your project would need to be in order to see it somewhat clearly.

Start with a multi-cut-out prototype & tape.  Once you've figured the sizes for your parts, disassemble and use a prototype 1-piece pattern with tabs & slots to hold it together.  Work it till it works  :-)

Designing one is relatively cheap. Building a prototype is not so cheap. You would need to use precision linear stepper motors or other actuators and their power supplies and  cooling systems and so forth.\n\nI suppose that if you already have a lathe or milling machine you could possibly modify it by replacing the manual positioning and stock feed or tool advance controls with the above computer-controlled steppers, etc. I don't think it would do as good a job as a commercial unit. You would have to have a separate controller for each axis or each degree of freedom that the machine can work in. \n\nHave you tried looking for a used cnc machine that someone might be replacing with a newer unit? It is rare that they would just junk them; you might be able to find a used one or a model that is no longer in production. Try contacting manufactureres. Those are my best ideas, Hope they help.

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask. It is done by using the principles of the kinetic theory of matter.\nAnother cool project might be doing something with dry ice. Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions. Make some dye molecules or something.\n\nHope one of these ideas works for you.
