Integrated System Build & Test
Team Vision for Integrated System Build & Test Phase
In this phase, it was our main goal to assemble most, if not all, of the subsystems of the Martone and integrate them with one another in order to proceed with integrated test-plans. In an ideal scenario, all of the individual test-plans will have been completed at the beginning of this phase if not earlier, allowing preliminary construction to take place.
Due to the current epidemic crisis and the efforts being taken to minimize the spread, and the fact that the various facilities on campus that have the equipment needed to complete these tests being closed, several of the test plans were not able to be completed, and hence the construction was also not possible. As a result the test results and their summaries are now being shifted to instructions on how they were meant to have been carried out.
Project Plans and OutlookBased on the current Pandemic, a recovery plan had to put in place to make sure that even though the actual building of the Martone is stopped, we deliver all the necessary documentations for future use.Please find below the updated Plan of MSD2.
- All items purchased and received have been handed off to Juan; the system assembly and presentation at imagine RIT will no longer be a reasonable deliverable due to COVID-19
- The electrode board is currently being shipped to Juan's location
- One final purchase order by the MSD team was made: Order #15254. This order was for speakers, a header pin, and a missing part for the main PCB. The team has discussed this final order with Ken, and will follow up with managing the situation in the final phase. Click here to view the order.
Update: Martone Physical AssemblyThe Martone is not assembled as the frames were never finished. Some parts are printed, others are not. All parts are in the customer’s hands now as prototyping has ceased.
Update: 3D Mechanical ModelingThe Martone is fully assembled. Newly added features include tripod legs, new speaker grill, new speakers, connector inserts, electrode tongue, and all connectors. Optional models that can be made are the press for the speaker grill and the Martone strap clips. Everything else is done. Drawings for the new tripod holder (what the machine shop would need to machine it) need to be remade as the geometry has changed.
Full assembly photos, cross sections, and important views can be found in this folder.
What was Added/Changed/Improved
Jacks & Inserts
- Design of the jack-holding inserts have been
finished. The models take into account:
- Fitting the latest designs for legs designed by Matt S (retracted and expanded).
- Accessing the legs with at least 2 fingers to pull them out of the instrument.
- Wires from jacks and proximity sensor going back into the instrument.
What was Missed/Overlooked
- When feet are expanded for vertical position, they allow access to the 1/4" and 1/8" jacks but block access to the USB breakout board.
- When instrument is setup for vertical positioning (standing on a surface), there is very little room for plugs to be inserted into the jacks. For USB and headphones, they may be able fit. However, many 1/4" plugs will extend further than the legs will rest, making impossible to have the 1/4" plug inserted while the instrument stands on a surface. This has no effect on horizontal positioning.
- Some fit testing has been done with jacks and inserts. Minor changes are still needed to make sure fit is snug.
- Fit testing of inserts with body has not been performed due to the global pandemic.
- Testing of USB board with charge controller to ensure it can provide the necessary current has not been tested (same as above).
- Testing of audio jacks to make sure they direct signals appropriately based on what is plugged in has not been tested (same as above).
Update: CAM for Martone FramesI (Sylvain) had just finished a class on Fusion360 G-code generation for a spoon that needed flipping for two-sided CNC milling. This module prepared me perfectly for the needs of the Martone frame. However, as all prototyping was ceased, I have yet to create the CAM for the upper Martone model as other priorities came up (3D modeling, writing, etc.). I need to create three g-codes: (upper Martone Frame, spoil board pin holes, hole drill in stock). Once these are made the CAM will be completely ready for final assembly in the future.
- Recall, lab tests for the current speakers were done in the previous phase as well as the newly ordered speakers. That lab report can be found on the phase 6 edge page.
- From the report, we know that the audio shield by itself cannot supply enough power to the external speakers to satisfy the ER.
- Therefore, feasibility analysis was done and a new solution was generated here
- Future outlook: Add an audio amp to the output of the audio shield to boost power, and order new speakers to do test this with.
Update: Battery and Voltage Controller
- Lab report and results for this module done in phase 6. See the phase 6 page for details on the lab and the results.
- NO CHANGE in phase 7 to this part of the project.
Update: LED PCB Test Results
- The LED PCB Test results can be found here.
- There were no issues with continuity and the 5V travelled through each PCB individually with no issues.
- The total time delay (assuming enough samples were taken and all LED PCBs had the same time delay) came out to 1.04ms
