Prototype 3

Posted by James Flynn on

  Prototype #3 This 3d printed prototype was made at Shapeways It fits perfectly on the iPhone 4    That one step closer to the final product.  The integration dome is working well and getting good readings.  I think it could be bigger to collect more light for the camera.  We tried to use printed domes, but they were not the correct translucent material.   The dome needs to have 18% light transmission.  Luckily we found stock sheet material that has these exact properties.  We then had to form that material in to the dome shape we needed.

Printing Prototypes

Posted by James Flynn on

We have made some cad Models of our prototype and are sending them off to Shapeways.   They will take our 3-d model and make a real physical prototype.    It's amazing to see a virtual model you have made in a computer just arrive in the mail.     3-d printing is awesome!

Light Meter Prototype 1

Posted by James Flynn on

Our first try at an integration dome to use as a light meter.  I made it to fit my iPhone 4  covering the front camera ( used for facetime)  We also found a lightmeter app that can access this camera.  The first proto actually works!   The Pocket Light meter app seems to work the best. We will have to test it against a real light meter soon.

Light meter added to an iPhone? Hmm...

Posted by James Flynn on

  Using a light meter as a learning tool.  After playing with my brand new D5000 for a while I wanted to try some manual settings. I took some photography classes in college so I knew the basics.  How the aperture and shutter speeds effected the exposure. I was in the dark on how to work with the automatic light meter. In auto mode the the settings are all over the place. Even the film speed was running all over the place.  This gave me the idea to go back to basics. So, I borrowed a friends light meter.  This...
