Me Motor Music Box Project Report for Team #4

Project Summary

Our goal was to make a music box that played the song “Are you Sleeping”. We were give the frame and bells, but we were given the task of building the gearing and drum. We attached the motor to a block of wood and placed it just so that it will hit the CD that is also attaches the block of wood. The CD drove the belt that was attaches to the drum. The drum was a piece of material that was cut 32 times and then shaped around foam circles to make it perfectly round. We placed a piece of paper around the drum and glued pegs to it in the order of “Are You Sleeping”, as the drum turn the pegs trips hammers that hit the bells

Project Challenges

There were a couple of challenges that occurred during the project. The main one was trying to make a motor mount that hit the CD at just the right place. We ended placing a piece of foam between the motor and  that gave it a little bit of wiggle room. The second major problem was that we glued the pegs on backwards, so the hammers didn’t have enough time to reset between notes. Also some of the notes were a little off, we also fixed that.  The supports inside the drum ended up being too small for the drum. We fixed that by cutting new circles on the foam cutter. We also had a hard time finding a way to meet outside of school because of work and other challenges in our lives

 

Me Motor Music Box Project Report for Team #3

Project Summary

It was the task of our group to build a musical instrument that could play the tune of “Are You Sleeping” at 60-90 bpm. With the use of a drum, motor and hammers, we had to build a musical device whose notes were played by pegs moving hammers, which in turn struck chimes to make the tune.

Project Challenges & Insights

 The main problems we encountered were those having to do with the timing of the drum itself, as well as the hammers not being moved by the pegs (as well as the opposite when the hammers got caught on the drum itself). We overcame these difficulties by a mixture of sanding the hammers and general tinkering. It also turns out the drum was more of an oval shape in some places, this we overcame by adjusting the rest of the pieces. We learned that teamwork is necessary to build a well-functioning musical instrument.

Me Motor Music Box Project Report for Team #2

Project Summary

Our team constructed a motor music box with several components: a gear box, a cd to slow the turn speed, a drum, a wooden base, hammers, and bells. Over two weeks we spend several hours planning and constructing the parts for the project. From there we assembled everything with out fair share of trial and error. 

Tom worked on the gearing and assembling the project parts to make it a whole. This included attaching the wooden base, the gears, the bells, and the fine tuning of the project. Alex Harrison drew the lined paper ( 3 times due to the fact that we messed up the notes once)  for the the notes and calculated where the notes should go. He also created the drum by measuring and cutting the drum itself. Rachel helped  Tom sauter the wires and took the majority of the pictures for the video. She also assisted Alex in cutting the foam. Austin made and put the video together. He also helped Tom with attaching the parts to the wooden base, the gears, and the bells and the fine tuning of the project. The other Alex cut out the styrofoam for the inside of the drum.

Project Challenges & Insights

The planning phase of our project actually went the most smooth until we deviated from the plan. Our original idea was to mount the the motor right next to the mounted cd and the drum. But instead we tried to use wires to hold up the cd next to the motor in order to give us some room for error if we mounted it in the wrong spot, but the wires were not strong enough and the idea failed. So we went back to our original idea and it works well.  The second problem we encountered was that the metal hammers were too close to the drum and would catch and slow the speed. From there Tom and Austin filed the hammers down so that they would still catch on the wooden knobs but not the drum. Another problem we encountered was the notes themselves, one of our group members put the notes on backwards so it required us to make a new lined paper and start again. From there we used some small metal to glue to the paper to save the old song that was backwards so we could hear what it sounded like. Yet another problem arose because the metal pieces were not tall enough and it messed up on eighth notes. After this the group was tired so we salvaged the wood chips from the first failed attempt and used them on a third lined paper for the drum and it worked perfectly. If our group were to start this project over we would stick to our original plan instead of trying to change without trying it because it could have saved us some time. The second thing we would differently  would be too take in consideration what other groups are doing. If we see they tried something and it failed it will save us even more time. If something they did worked we could make our own version of it to see if we like it. From this project our grouped learned that not everything is simple and that engineering is all about trial and error. Most times it will not work out the first time and it will take persistence. Some advice for future groups is too stick to one idea to the end and to delegate the easy things but do the hard tasks together so everyone is on the same page.

Me Motor Music Box Project Report for Team #1

Project Summary

We built a wooden base to hold the motor and attached the first gear to it. The next gear was attached to the end of the drum. The two gears were connected and ran by a belt made of electrical tape. The drum material for the drum was cut into 32 even sections so that it could bend into a circle. Then foam discs were inserted inside to make it almost perfectly round. Once the drum was assembled and sturdy we hot glued the pegs onto the music roll and taped it onto the outside of the drum. When the motor runs it turns first one gear and then the other gear which is attached to the drum. The drum then spins. As it spins the pegs on the music roll come in contact with the hammer. They cause the hammer to rise and then fall down on the bells, thus playing the song “Are You Sleeping.”

Project Challenges & Insights

There were a few challenges as we progressed through the project. The first being how to make a mount for the motor. We decided to build one using wood, that way it would be very sturdy. The next problem was the support discs for the drum were too small so we wrapped them in tape so that the fit inside the drum and supported it better. Finally we had the problem, at the very end, that some of the notes of the song couldn’t be heard. We had to change a few of the pegs so that they were larger and would make the hammerer actually hit the bell. We also had to move a couple of pegs slightly farther apart so that the hammer had time to fall and hit the note and then go back up and fall again.
