How to transform a USB Webcam into a microscope? | |||
== Microscopy stage == | == Microscopy stage == | ||
One of the first steps is to work on the design of the stage to fix the microscope. | |||
< | |||
It is important to make the drawing in the right scale. For my design, I took up the idea from the origins of the microscope where the eyepiece, the lenses and the arm are on top and the light, the aperture and the object are on the lower part. | |||
In this case, the lens is placed on a platform that can be moved up and down trough a threaded rod. This rod is fixed with nuts to the stage. The base consists in a kind of box with a hole to put the slide, which contains the object. | |||

The disassembly of the camera is not an easy task. All the pieces have to be removed, including the LEDs (unsolder), until only the PCB is left. | |||

The lens has to be inverted and fixed to the PCB. | |||

== 3D Model == | == 3D Model == | ||
During the whole design process some small changes were made. An example of this is the platform slot, which allows the movement in every direction, also the size of the aperture and later the small pieces to hold the slide. | |||
The 3D Model shows different views of the prototype. | |||

== Cardboard Model == | == Cardboard Model == | ||
The best way to know if the prototype works is to build an actual size model. | |||
I used model making cardboard because is cheap and excellent material. You will also need some kind of adhesive, a cutter, screws, nuts (butterfly, hex, cap), a threated rod, washers and a small piece of acrylic. | |||

I decided to use Acrylglas for the final design. Because of the material and the size of the pieces, it was necessary to use a laser-cutting machine. | |||

==Inspiration== | |||
I saw an exhibition last month in Mexico, the pieces [http://www.youtube.com/watch?v=M-NMwnToWwE shown in the video] are like portraits of a microscopic world. The artist's name is Fernando García Correa. | |||
