Midterm Review and Project Planning

Objectives

Show progress on final project

Make a plan for remaining tasks

Final Project Progress

I have been picking away at different aspects of the project. I have in particular spent a lot of time trying to project rainbows on to walls and people and have built some of my weekly assignments around trying to find a workable solution that fits in a relatively small form factor.

Link to conceptual development which has lots of prior work.

Link to Output Week where I did some work to create rainbows.

Questions to Answer

My final project will have 3 functions:

Rainbow projections

Rainbow flares

Adjustable color vignetting

Rainbow Projections

This still has the most work left to do. I have found that the quality of the rainbow projection depends on the quality of the LEDs as well as the quality of the diffraction grating. So I still need to tune on this.

Rainbow Flares

I have found a number of materials that will help create these and it is just a matter of putting the diffraction grating over the lens. This is mostly a mechanical packaging challenge.

Adjustable Vignette

I have an idea of how to do this by molding a silicone snoot for the lens. This will be the priority for molding in week 13. Then I will just have to figure out how to get the LEDs to pipe light through it properly.

General

I do have some questions about how much power it will take to run the device. Once I lock onto an LED system that works, I will be able to properly spec the battery. This will be a primary driver for the overall size of the device.

I also want to make the product look sleek and integral to the camera. So I want to be clever about the design and will try to make it so the effects can be merged. This will be worked out in system integration week.

I also want to add an app to control the color of the vignette. This will worked out in week 14, Interface adn Application programming

Final Project Skedge

Concept Modeling

Complete by end of April

Figure out the featureset that makes sense

Figure out what LEDs work for flare

Find a good way to make rainbow projections

See if can get good light through silicone/ stretchy stuff
