Final Project - Making my own camera

My goal of this project was making my own lens with material such as a small magnifier which can be found easily rather than using existing one. I wondered if I can actually make a camera with it. I tried to make my own lens while testing with several types of magnifiers and came up with choosing two different sizes of magnifiers to simulate a lens. 

I placed a smaller magnifier closer to the sensor and placed a larger one farther from the sensor. And then wrapped it up with duct tape to block all the light.   

I decided to make a prototype with a sensor and two magnifiers. I placed materials in line and put them in a cracker pack and tested while manipulating the distance between the sensor and magnifiers.

I ended up with getting a result that is showing blurry enlarged image when I pointed at the power supplier blinking green and red light. 

Here is the video that I recorded while I was shooting it with my prototype. I loved seeing the image that showing really beautifully out-focused green and red light. 

I decided to make an actual camera using Lego.  And I got the same result which is that I can barely see the color difference of an image.

I changed a material with really thin black foil and ended up with making a pinhole camera at the last minute. it gives me more clear image when I shot in really bright place. 

I was trying to make pinhole camera using a lens cap as well. it shows more blurry out-focused image than when I use the thin foil previously. When I used the foil, the sensor was getting really low exposure, so I thought it was because the hole is too small. So I made a bit of larger hold on a lens cap and it caused a result that more blurred image. Also, the thickness of a lens cap was thicker than a foil, so it might be another reason for this result. 

This is the image I took when I was shooting a rainbow flag. I got this blurred rainbow image from it. I think I can get more focused image if I make the distance between the sensor and a hole much closer and make a hole a bit smaller. But I'm not sure how to manipulate it to get the right exposure.
