Project Title

Bulb Ramper

Abstract

Time-lapse photography is the process of taking many exposures over a long period of time to produce impressive short videos and photos, which create a feeling of traveling quickly through time. While the ability to create time-lapse videos or photos is available to anyone with a camera and a fairly inexpensive with a trigger controller, the ability to increase exposure time (bulb ramping) while moving the camera is not. Moving bulb-ramping device currently on the market cost hundreds of dollars. Our team intends to create a bulb-ramping device that can rotate 360 degrees around and, will trigger the camera shutter in sync with travel and will also have the ability to pan as it travels.

Objectives & Introduction

The goals of the mechanical design will be to create a physically robust gear that has a professional appearance and has little environmental impact, all while performing its job in an efficient manner. The goals of the software design will be to create efficient and professional C code that performs all required tasks while minimizing the possibility of software and hardware conflicts. 
The microcontroller will be the operating brains for this project, interfacing with the motor driver to provide linear motion from the stepper motors and rotate the camera panning head. Coding will allow the operator to set a variety of attributes related to camera function. For example: 1. Number of pictures to take 2. How much exposure time to ramp in a specific period 3. Time between pictures 4. Rotating the camera platform Overall all the design will be handled with a top-down systematic and methodical approach.

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

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Issue #1: Need to decide task importance. After camera task starts taking pictures, what do we need to do to interrupt it (i.e., stop it?) Issue #2: Modification of individual variable are complete. Need fine tuning. For example, "A" & "G" buttons increase/decrease values. Need to implement two other buttons to select which decimal place to change. For example, instead of increase by 1 every time, increase it by 10 or 100 instead.

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?

Project Video

Upload a video of your project and post the link here.

Project Source Code

Send me your zipped source code and I will upload this to SourceForge and link it for you.
