Project Title
Seismograph
Abstract
In recent years, news of an upcoming large scale earthquake in California has been increasing. Having a seismograph would allow us to directly see any seismic activity. In addition, by adding an LCD screen, we would be able to add plots of the data in a time series manner for any research purposes. Most importantly, the seismograph device would allow to help with search and rescue efforts. When a large scale earthquake is detected, it would allow a signal to be detected via your cellphone in order to ping your GPS location in case of a building collapse.
Objectives & Introduction
Our seismograph would help bring awareness to the realities of earthquakes in California. In addition, it has the possibility to help save lives by aiding in search and rescue efforts when a large earthquake does come.
- Create a working seismograph and store data onto a microSD card
- Write software to display data onto an LCD screen
- Add to software to send signals to cellphone via Bluetooth
- Write a small mobile application to receive data via Bluetooth
Team Members & Responsibilities
Both team members will be working on all areas of development with specific focuses as follows:
- Mina Yi
- Focus on software
- Display data on LCD screen
- Mobile application to recognize signal
- Focus on software
- Andrew Ahwal
- Focus on hardware portion to build a working seismograph
Schedule
- Responsibility and leadership of the task is indicated by the Assignee.
- However, it does not mean that they will be expected to complete the tasks alone.
- Subtasks are listed in the comments section and are numbered.
- Subtasks will be delegated as seen fit.
- Any deviation to the schedule due to technical issues will be covered under the Testing & Technical Challenges section.
NOTE: Documentation is not specifically listed in our project schedule. However, each task has a documentation phase before and after each task.

Design & Implementation
The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.
Hardware Design
Discuss your hardware design here. Show detailed schematics, and the interface here.
Hardware Interface
In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.
Software Design
Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Testing & Technical Challenges
Documentation Issues
One of the largest deterrents in our project was due to poor or little to no documentation.
Working with the ST7735
There were problems initializing the LCD screen since the documentation was not very helpful. In addition, the board was originally intended to be used with an Arduino so we had to port the Arduino code over to work with our board.
HC-06 Bluetooth Module
Bus Contention Issues
Conclusion
Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
