Are you a fan of The Most Useless Machine Ever?

Now you can have one with you all the time with The Most Useless iPhone Case Ever!

Check out the video to see it in action: http://youtu.be/eyYIcQd2hkE

For some more details about how it was built, check out http://jherrman.com/2012/03/the-most-useless-iphone-case-ever/.


The case is split in two below the volume buttons on the iPhone. The lower portion is actually two pieces screwed together - one that holds the iPhone, and one that holds the electronics.

In addition to the prints themselves, this project uses a number of components.
These should be as small as possible. I was able to find a small motor and
gearbox from an old digital camera and webcam. I had the battery case, toggle
and lever switches leftover from various projects.

DPDT Toggle Switch
SPDT Lever Microswitch
DC Motor
Gearbox for motor
Battery Holder 4xAA
4 AA Batteries

This file depends on an iPhone 4 openSCAD model.

Just a warning: The OpenSCAD code is messy and was thrown together pretty quickly. I started a big refactor but ran out of time.

That's not useless. It would be perfect as part of a pinball machine. :-D At first I was actually thinking it was a case that turned the phone off as soon as you turned it on like this http://www.youtube.com/watch?v=Z86V_ICUCD4http://www.youtube.com/watch?v...

It actually is exactly like the machine you linked to, except it can hold an iPhone. You're right - it would have been great to get the case to hit the power button on the phone!
