Write problem/project Goal
What is your wording of the overall problem/project goal?

My First Task
What are you going to do for the team this first weekend?

Summary of actual work over first weekend
In this week I wanted to determine what kind of music project I wanted to do. So the beat maker seemed to be a very interesting and I begun to do research.

Week1 Narrative
After researching there is a video of the project I want to make Ball bering beat maker

Along with this video there is a tutorial on Make magazine on how to build it Here are some pictures of what the project I want to do looks like.





My Second Task
For my second week task I plan on building the plastic board to hold the bearings.

Summary of actual work over second weekend
In this week I didn't get around to building the plastic board. Most of my time was working with the Arduino and midi shield to control a midi device.

Week2 Narrative
The first task was to connect the midi shield and solder the midi plugs and pins to connect to Arduino.

Before I show the process of soldering the midi shield here is a video of how to solder.

How to solder

The first thing I did was solder the midi connectors onto the midi shield. Shown below is the process of soldering the connections.







Now that the midi connectors are soldered on I needed to add the pins that allow the shield to connect to Arduino.



After the pins were soldered I connected the Arduino and midi together.



My Third task
My third task will be to construct the ball bearing board.

Summary of actual work over third weekend
In week three I planned on making the board, but I decided it would be more beneficial to learn how to use a CAD software and draw a 3D model of the board.

Week3 Narrative
In week three I thought it would be really cool to learn how to use a CAD software. So at work I have access to a program called Pro Engineer. It took me a very long time to learn the basics of the program, but once I did it was very fun and excited to create this 3D model.



My Fourth task
For my forth weeks task I plan on using my CAD model to have a board CNC machined at my office. I figure that this will help out the next group who decides to try and make the beat maker.

Summary of actual work over fourth weekend
In week 4 I planned on drawing a complete detained CAD model to have CNC machined. I completed the CAD model but would have not been able to have it machined in time.

Week4 Narrative
in the beginning of week for I drew a complete detailed CAD model of the board that we wanted to make. Below is the step by step screen shots of the drawing.

Here is a link to the code that can be used to regenerate the CAD modelBeat_bearing_CAD_code



After drawing the board I begun to work on the wiring the consisted of soldering ribbon cable onto washers that had been cut in half. I cut 32 washers in half to fit the 4x8 grid that is molded in the CAD drawing. Then the ribbon cable was cut periodically shorter as it moves down the row. After that the washer needed to have a rough surface on them to help the solder adhere to the smooth surface. While cutting the washers and soldering them to the ribbon cable I made to video tutorials of how it was done.

Here are two video tutorials I made for this process.
