Project Update

June, 2019: The product was successfully field tested and handed off to the client. Scoreboard functions worked with manual and wireless controls. Bluetooth Speakers and soundboard functions worked well, however, the individual Bluetooth speakers were discoverable devices the made unintended connections sounds from random people attempting to connect during the game. Fortunately, these speakers were intended for this situation and are wired as AUX-out setting to a MUX Bluetooth module that needs manual press and connect Bluetooth pairing for a new device to pair and play sounds trough the scoreboard.

Nov 20, 2018: The project CPI and SPI are within the new limits. This means that the project is currently on schedule and budget . The prototype scoreboard is functional using push-button control, as well as through wireless control via SSH to the PI. The Raspberry Pi is able to send the desired values to the Arduino Uno and have them display on the scoreboard. Testing of the scoreboard is completed with the exception of wireless control using a webpage. The testing protocol for the scoreboard and user manual for the scoreboard are completed. The final scoreboard enclosure is welded and has been painted. Wire labels have been printed and put on all electrical connections. The prototype scoreboard is wired and ready to be transferred to the final enclosure.

Nov 6, 2018: The project CPI is within the new limits, and the SPI is slightly above the new upper control limit. This means that the project is currently ahead of schedule and on budget . The prototype scoreboard is functional using push-button control. The speakers, microphone, and Bluetooth module are wired and mounted in the scoreboard enclosure. Testing was done using a loudspeaker app in lieu of a physical microphone, and it works as intended. Testing of the scoreboard has continued, and the first draft of the operation manual and testing protocols are written. The final scoreboard enclosure is manufactured and has been delivered. The weldment assembly has yet to be completed but has been started. The Raspberry Pi is set up as a router with a static IP with an Apache web server on it to give access to a default web page. The default web page is being designed for wireless control of the scoreboard.

October 23, 2018: The project CPI is once again 20%+ above the upper limit, and the SPI is approaching the lower limit, which means that the project is once again behind schedule and under budget. The prototype scoreboard is functional using push-button control. The speakers, microphone, and Bluetooth module are wired and mounted in the scoreboard enclosure. Testing was done on the speaker system and Bluetooth module to ensure they operate as intended. Testing of the box has started, and the testing protocol has started to be written. The final scoreboard enclosure is being manufactured and is expected to be delivered by the end of the month. The Raspberry Pi has been flashed with Raspbian, set up to operate as a wireless router, and has software installed for it to default to a website when accessed. More work on the Raspberry Pi will be done this weekend and in the coming weeks.

October 16, 2018: The project CPI is 20% above the upper limit, and the SPI is approaching the lower limit, which means that the project is currently behind schedule and under budget. The prototype scoreboard is functional using push-button control. The speakers have been placed into the box and ready to be wired with the Bluetooth module. The Raspberry Pi has been flashed with Raspbian, set up to operate as a wireless router, and has software installed for it to default to a website when accessed. Testing of the box has started with more testing to take place in the coming weeks. There were grounding issues with the buttons to increment and decrement the displays, as well as an issue with the relay controlling the globe lights for the top and bottom of innings. There was also an issue with being unable to download software to the Raspberry Pi once it had been configured to operate as a router. The speaker system needs to be tested with a microphone and wireless controls are still in development.

October 9, 2018: The project is currently behind schedule and under budget. The build phase of the scoreboard prototype is 65% complete according to the Gantt chart. The LED control boards have been soldered and confirmed functional with the Arduino micro-controller. The Arduino code to control the scoreboard with buttons is complete and verified using 2 LED segments and the buttons from the scoreboard. Two of the three LED control boards have been integrated into the prototype scoreboard. The wiring of all LED segments and globe lights is nearly complete. The push buttons to increment and decrement the displays will be wired next, and another button to reset the micro-controller will be installed. Wireless control is still in development and is planned to be finished by the start of November. The next step is to set the Raspberry Pi as a wireless router and test connectivity with various devices. The current plan is to begin testing the prototype assembly after October 17^th.

September 26, 2018: Wooden prototype box was built successfully, and to the same scale of the final unit. Code for the Arduino to output to the segments and globe lights is completed. Test rig containing one pair of segments attached to the Arduino was successfully assembled and operates properly. Raspberry PI flashed to have Linux, and work has started to allow it to operate as a wireless router. Started initial wiring and mounting of the prototype unit. Terminal blocks were mounted and installed, wiring for power lines to segments and control boards was started, and segments were mounted to the board. LED driver boards were soldered for the prototype, but when connected to the test rig the segments were displaying incorrectly. Weekly meetings have been started as a part of a collaboration with a Manufacturing Technology student to build the stand for the final unit.

Sept. 21, 2018: Design revised to version 1.4. Components purchased, prototype construction in progress. Scope package (Scope Statement, Gantt Chart, Risk Assessment, Budget) updated to version 2.0.

May 5, 2017: Design version 1.0 completed. Working on improving the circuit design and making a parts budget. Mechanical layout in progress. Scope statement and Gantt chart completed. Risk assessment in progress.
