Hello,

I finished making this last night and wanted to say thank you for the design and offer a few comments. The design is quite good, and is one of the few things I've been able to print that has multiple pieces that fit together with each other (as well as with other components) easily, with no adjustments to scale or post-print sanding needed. Even the arduino lines up with the hole right where it should!

That said, my first suggestion would be to add an image of the underside of the perf board--you don't show it in the video or the instructables page, and it took a little planning to figure out where everything needed to sit and where the traces should go. I tried wire wrapping first, but it didn't work so well with short leads so I tried drawing out the lines with a conductive ink pen and ultimately touching that up with solder, but it would be nice to see how you connected everything.

I would also suggest adding a switch and/or button and a battery to your next version. Having the USB cable is nice if you want to change the speed or have external control, but if you just want to mount this on a tripod somewhere it's a slight hassle to manage a USB battery as well. Not a major issue, but worth considering, I think.

As for the lens being off-center, it doesn't seem to make a tremendous difference (although I do think it's pretty close right now), but I have found that the weight of the phone is tilting the mount a bit, and if it's not on the tripod it can tip over.

For the cardboard camera, I'm finding that it works better when slowed down to a single rotation in a minute. It's a little jittery at that speed (and you hear the clicking of the motor in the recorded image), but so far the image is clearest for me at that speed--although I've also found that the built-in camera app's "panorama" mode is significantly sharper than the cardboard camera...it's just too bad it doesn't capture a full 360 that way.

Lastly, another thing to consider in future versions is tilting the mount a bit (the part that holds the phone). As it is, I'm finding the picture looks up more than down, and if I tilt the whole thing on the tripod the rotation isn't level anymore. In fact, if you could have a few angles for holding the phone, this would be a terrific way of doing photospheres too!

Oh, and one question: what's the extra hole on the top for?

Anyway, great design and thanks for sharing it!

Hi,

I really like your idea, but there is a small thing that can easily be improved.
Your lens should be directly above the tripod mount, not a few centimeters to a side. This will compensate for the nodal point and give you perfect overlaying pictures no matter if the subject is far away or close to the lens.
It's an easy fix in the 3D model, so not much of a problem to do.

Great post. Thanks for sharing it. :-)

Sincerely,
Brian.

hi , thank you for your comment
you are right , it should be directly above the tripod mount but i did this in the first prototype to minimize space and because of the stepper motor shaft is not at the center.
i'll fix that in the next update :)

Sincerely,
samir.
