Origami Helps Cellphone Cameras To Focus

Sea Monkey writes "New Scientist has an article on the development of novel and ultra-cheap micromotor technology. It's a new type of linear motor, 'using a technique closer to origami than engineering' to cut slits out of tiny piezoelectric ceramic parts. One of the envisioned applications is taking a sheet of the material with the motors, wrapping it into a tube and moving a lens up and down it - instant tiny movable focusing element for cellphone camera lenses."

Cellphone camera focus improvement - geek way

[Krapangor]

Well you can do the same with standard geek tools.
Take 2 empty Pringles cans with intact lid. In fact one can with 2 lids will be sufficient.
Remove the bottom of one can.
Put one lid on the bottom and glue it hot glue.
Fill can with water.
Put the other lid on the top. Make sure that there are no bubbles in the can.
Glue the top lid.

What have you now got is a high quality ultrasonic lens with will greatly improve the focusing of your cellphone cam or any other cam with ultrasonic focus.
