A M4 thread has a pitch of 0.7 mm, which means that one rotation about its own axis will move the lower sled 0.7 mm and consequently the upper sled about 0.2 mm. As a result, the microscope can be adjusted very fine in its height. | A M4 thread has a pitch of 0.7 mm, which means that one rotation about its own axis will move the lower sled 0.7 mm and consequently the upper sled about 0.2 mm. As a result, the microscope can be adjusted very fine in its height. However, compared to the cases built by my fellow students (see [[GMU:DIY-Microscopy#Works|Works]]), my approach is quite complicated and a bit more expensive just to fulfil the same functionality. | ||
''Note:'' Unfortunately the 3D printer became damaged; so, the case itself is built out of Balsa wood and could not be printed during this course. The sleds were printed before the printer fell off the table. | ''Note:'' Unfortunately the 3D printer became damaged; so, the case itself is built out of Balsa wood and could not be printed during this course.

Currently, I am working on a [http://puredata.info/| Pure Data] patch to help Max with a blob tracking algorithm. Since I am new to Pd, I just did not finish my work yet, but I will upload the patch as soon as it works. | Currently, I am working on a [http://puredata.info/| Pure Data] patch to help Max with a blob tracking algorithm.

In her talk about the basics of microscopy, Adriana showed us some nice images captured with microscopes such as the ones on [http://scienceblogs.com/retrospectacle/2007/01/30/beer-microscopy-project/ this site]. Since I liked the way the artists colored their specimen, I asked myself how to achieve a similar effect with possible cheap equipment. | |||
So, I considered to dye sugar, salt and meal with food coloring and then take gaudy images of it. In the photo to the right, one can see the condiments drying at a radiator after coloring. | |||
Here is a gallery of some images I shot: | |||
