Team Vision for Integrated System Build & Test PhaseSummarize: In this phase our team originally set out to finish both the 3D printing and soldering while taking great strides with respect to construction and software development.
During this phase our team was able to finish 3D printing, coil detailing, and construction. Progress was also made with respect to software development an soldering.
- All of the pieces required for construction have been printed.
- The coil resistances were compared against pairs and the expected resistances and were modified to match.
- Then the coils were attached to a power supply and the Gauss was measured using a magnetometer and the same voltage.
- The current was also examined to ensure they were matching.
- Once this was complete a silicone covering was used to help protect the coils and form a more permanent construction.
- A silicone layer was also applied to the inside of each coil to prevent any damage to the coil wire.
- Three zip ties were added to each of the coils to hold the flexible wire in place to prevent any damage if the wire is pulled
- A silicone layer was added over the extruding wire to prevent any further damage as well
- This is a temporary build, which used duct tape instead of permanent glue
- This is the completed execution of our design
- Silicone was used in place of the cyanoacrylate in some locations because of it's "void-filling" qualities
- For strength reassurance, a new "cross-bar" was built
- Cyanoacrylate was used to adhere the PLA pieces to the wood.
- Many wires were made to connect the coils to the relay board and the power supply to the relay board
- Banana plugs were attached to the wires for easy connection and disassembly
- Heat shrink was used to protect the wire where soldering occured
- The wiring followed the previous schematic
- The wires were attached to the relay board according to the schematic
Power SupplyThere was successful communication between the power supply and PC using MATLAB. The power supply outputs were controlled from MATLAB using a simple script. The power supply code can now go through further development.
Initial TestingThe apparatus was setup and inital testing was performed. The results can be seen in the video here.
Initially you can see the testing apparatus and the power supply it is attached to. A magnetometer is shown in the middle of the apparatus. Then a single pair of coils is turned on at a time. The magnetometer records the readings and graphs them on a 3D space. The results show each coil pair produces a a change in magnetic field in one direction as desired.
Some screenshots displaying the results can be seen below. Again, the three distinct axes can be seen.
Risk and Problem Tracking
Plans for next phase
- Commence testing
- Work on Final Paper and Poster
- Finish developing software
- Put electronics in a housing
- Finish Construction (including setup protocol)
