Team Vision for Detailed Design Phase

With major strides being taken in the last design phase, we were looking to end the semester and MSD1 properly. In order to do this, we needed to create a real wooden coil and develop our plan for MSD2.

With great hustle and, at other times, patience, all of our real wooden coils were assembled. Additionally, our MSD2 plan came together showing how we speculate next semester is projected to, ideally, happen.

Revised Cutting Pictures

With the realization that out previous sketches were not optimizing our wood use, we went back and redid the cut patterns. With more plywood research, we also updated the size of the plywood. This resulted in us needing to buy less plywood and save money. Each sketch is for each piece of plywood, respectively.

Wood Selection

We opted for two .25" x 60" x 60" pieces of baltic birch plywood. This wood was chosen for the following reasons:

Painting & Sanding

Now that our coils are assembled, we need to sand off glue residue and apply two coats of our spar urethane to finish the job.

Wrapping (Proposed Method)


Bill of Material (BOM)


This is the most recent BOM. The most significant change is that the plywood has been purchased.

Design and Flowcharts


This is the proposed circuit to give the coils the full range of voltage. Ideally, double pull double throw relays would be used to switch both coils using only one input, but for the relay boards available that are compatible with the Arduino, they are limited to single pull double throw. It is important to note that the coils will only switch when the voltage on them is zero. Due to this, any inductance can be ignored.

Magnetometer Development

We were granted access to use a calibrated magnetometer in order to further verify our method of calibration. Unfortunately we were unable to obtain correct readings from the calibrated magnetometer in relation to what we were expecting. As we were in a lab with a lot of metal and electronics, we are inclined to believe the exhibited error was due to the local environment.

Risk Assessment


This is the risk chart with minor updates.
