15 dollar BGA working Camera

Such a camera cost 250 dollars or more from china. I give you the way to make a working one for 15 dollar !!!

Get the materials :

1 5MP webcam orderded on aliexpress.com for 6 dollar
1 X8 zoom for iphone 4 on aliexpress.com for 9 dollar
1 2" plastic tube
some electrical tape or heat shrinkable tube

A 8x zoom for iphone has a 5 or 6 meters focal length. We want to get this point at 30cm in order to install the camera on or near the machine to focalise on the balls. All you have to do is to shift the first lense of the zoom of few centimeters (about 4) to get the focal length smaller. (More you shift, more you reduce the focal length)

Disassemble the zoom

Unscrew the ring and the small lense.

Make the assembly for the lense

Make a hinged support
You must make this support in order to make fine focus adjustment

Assemble the webcam on the zoom

First result with a bad quality webcam 640x480

And with a 2MP camera from china(7$)
