Macro lens for a Nexus One

[Thomas] tipped us off about a macro lens attachment for his Nexus One. As you’d expect, adding the lens helps the phone’s camera bring tiny details into focus. He re-purposed a lens from a pair of mini binoculars, using epoxy putty to make a mounting bracket. Now the last time we saw this putty used with a phone it was for a snap-in bracket that cradled the phone and included a lens adapter. Rather than go that route [Thomas] made use of the headphone jack just above the camera lens. An old headphone plug has been epoxied to the macro lens ring, holding it in place securely while remaining easily removable.

    using the headphone jack to hold it there is a good idea, and his photos look cool but the lens seems to be off-center and you can see a black partial ring around the edge of the pics

  2. zool says:

    also there isn’t that much of an improvement, just a sharpening/focusing rather than any derastic change in magnification

    my droid does a rather good job at macro but the camera SUCKS but this is an ingenious approach at it
    i prefer my nikon macro lens setup X3

    He could use the headphone plug for data transfer and adjust the properties of the lens, like some tiny motor or something.

  5. Elias says:

    @zool I think having the phone focus on something that close is kinda what macro photos are about for a phone, it is not supposed to be super magnifying. But I agree that the placement is quite bad as indeed you can see the black ring on the left side.

    epoxy putty is some of the best stuff to have on hand

  7. Hirudinea says:

    Using the Headphone jack is smart but what about phones that have the jack ina different location?

  8. Whatnot says:

    It’s odd that the phone manufacturers didn’t start putting some sprocket of sorts on phones near the lens yet to add such attachments.

    Whatnot: You might have a billion-dollar idea there. Get on it!

    you can get this with a lens from a dvd laser (the one that moves up and down). this was taken with 2mp cell camera and those pads are for 0603 and the wires are 32 gauge

  11. mick says:

    and yes i know the soldering is horrible but my iron’s tip was on its last legs

  12. Bharath P says:

    I did that not [Thomas]

  13. Quabinah says:

    This is a great idea, and a very well engineered prototype. The only thing I would add is rubber feet, and a screw-type attachment for the lens for fine focus.

  14. Spork says:

    Nice hack idea, but it seems that the “macro” capability just shifts the FOV closer to the camera and actually makes it smaller. Not exactly what I’d want from my camera, but if you *really* need your phone to photograph ram, then I guess it’s great.
