Rube Goldberg Machine: Choosing (Entry #1)

For my 20% project I chose to do the Rube Goldberg Machine. I chose this for my project because I enjoyed doing the first Goldberg machine and would like to take it to the next level. Creating a Rube Goldberg Machine requires a creative mind, which I posses.   I would like to learn more about the physics part of creating a Rube Goldberg Machine.  Although I would like to learn more about Rube Goldberg Machines, I would not like this to be my job.

Rube Goldberg Machine: Intro Research (Planing) (Entry #2)

To start the planning process first we read the instructions and watched some videos.  The videos were on how to build the machine and what they do.  I am pretty sure that I have a good idea on what we have to do to make our machine.  All we need to do is draw it out, get the materials, and build.   We have now begun to plan and will decide who will bring in what materials.

Rube Goldberg Machine: Intro Research (Planing) Part 2 (Entry #3)

We watched a video on a man who built a Rube Goldberg Machine.  It took him a couple months and was very complex.  He had balls rolling on tracks,  domino effects using a whole bunch of different objects.  Also how to rig some of the contraptions.   

Rube Goldberg Machine: Questions Answered (Entry #4)

Today we planned our project, what our machine will look like, and how it will work.  We made a drawing showing all of this.  On that same paper we labelled our items, said who would bring each item, and how it works.  We asked Mr. Ternet if  our drawing was OK to make into a machine and he approved it.  What materials you need, what items it takes to build a Rube Goldberg Machine, and how you combine the stages all answer questions on how to complete my project.  

Rube Goldberg Machine: Building (Entry #5)

Today we built our zip line and our track for our rolling balls.  The zip line will send a ball down on a pulley.  The ball that is on a pulley will hit the base of the track causing a set of balls that is resting on the track down.  The balls will go to a contraption that we hope to build soon.

Rube Goldberg Machine: Building (Entry #6)

Today we set up the course so that the zip line will hit the base of the track sending a ball down.  The picture bellow shows how the two contraptions join together into one big one.

Rube Goldberg Machine: Technical Terms (Entry #7)

To complete this machine I need to know what terms like pulley and zip line mean.  Pulley- a wheel with grooves that when a force or weight is applied to one side then the other side will raise upward.  Zip line- a cable mechanism used to transport.

Today I built a pulley-like system that will, when it is on, carry a set of yellow balls up and drop them into a bucket that will be attached to a pulley.

Rube Goldberg Machine: New Information (Entry #8)

Today we combined all of our stages together to get one big contraption.  We aren't done yet though.  We still need to build two stages and combine them into the larger contraption.   Hope we can get to the fine tuning soon!

Rube Goldberg Machine: Technical parts of the machine (Entry #9)

Today we built a bucket and added it on to the machine.  The bucket catches the dropping balls.  The bucket will be on a pully that will when the balls are in, weigh down the the pulley causing it to raise a curtain that is covering a poster. The  poster will be reveiled.

Today we were working on  the bucket and connecting it to  he main part of the machine.  The machine still has some parts that need a little work, but it I like it all the same.  We made the bucket but it is to heavy.  We need to make a new bucket that is lighter, I think we will lay off the duct tape.

Today we are working on our presentation in google slides.  We still need to do a few things to our project, but for the most part it is good.  We made the presentation and are adding our information to it.

Today we took apart our bucket and are trying to salvage as much duct tape from it as possible.  So far we have salvaged about 1/3 of it.  We are planing to make another bucket, but have it lighter and with less duct tape.  Today we also are replacing a lot of our duct tape and string because it is getting old a not working right.

(Entry #13)

Today we added another stage.  The stage that we added is a ball that is dropped into an air pump.  The air pump triggers the zip line that is in our machine.  The ball is a 4-lbs. weighted ball.  The air pump is a pump that goes with a toy rocket.  When we drop the ball onto the compression pad that the air pump contains, it should trigger it to shoot air.

Today we built the bucket that we mentioned earlier.  We built it using paper and duct tape.  the bucket is light enough that the pulley will raise up the curtain.  We still need to adjust the pulley system that is raising the curtain.  Also we need to work on our zip line because it is not working everytime we use it.

(Entry #15)

Today we were testing our machine.  There were some flaws with it and we were trying to work them out.  So far only our last stage has flaws and we were trying to fix them.  Our  machine has all of the stages in it and is ready for action!  Tomorrow we will test it and show our teacher our final machine.  Wish us luck!

Rube Goldberg Machine:
(Entry #16)

Today we are setting up and fixing the final kinks of our machine.  On our machine when we tested it, it turned out that the last stage, the pulley did not work.  The balls that were supposed to fall into the bucket did not always land in the bucket.  We had to fix this problem.  When the end of the class came we were not able to fix it in time.  Hope we can fix it tomorrow.

Rube Goldberg Machine:
(Entry #17)

Today we were trying to get are whole machine to work properly all of the time.  We had a little bit of trouble with the last stage again but we were able to videotape our machine working properly.  All of the balls fell in the bucket, all of the stages connected nicely, and our task was revealed, we revealed a poster/sign.   The curtain covering the poster/sign could have lifted up a bit more but it worked.

Rube Goldberg Machine: Reflections (Entry #18)

I learned a lot about engineering while doing this project.  I learned how to work pulleys, zip lines, convener belts, and how gravity can effect them.  Learning these things can help me later on in life, even if it is not building things.  Just because something should work (like in the Rube Goldberg Machine) does not mean that it will work.  We had many trials and errors in our machine.

My Rube Goldberg Machine in the end turned out great!  I think we did a good job and had a machine that turned out nicely. 

We had trouble with our last stage and had to do a lot of tweaking with it.  We eventually got it to work though, and that's all that matters. 

I enjoyed building the machine and I think that I will work on building one for fun, like over the summer.  Even though I enjoyed making the machine, I do not think that I would like to do this as a job or be an engineer.   

I do not regret my choice of choosing the Rube Goldberg Machine.  I enjoyed planning it out, building it, and fixing the mistakes in it.  I do not think that I would have enjoyed another project as much as I did this one.  The Rube Goldberg Machine really lets your creativity shine through.
