== More Approaches == | |||
After having built the microscope and knowing its strengths and weaknesses, I started to think about more things to with this and other microscopes. Here are some ideas I wanted to follow: | |||
==== 3D microscopy ==== | |||
Basically, there are three methods for getting 3D images of your specimen: | |||
* having a special lens so that the camera is able to look at the specimen from multiple view points at only one certain point in time ([http://phys.org/news/2011-03-stereo-lens-d-microscope.html| see this article]), | |||
* using two cameras to get two images at one certain point in time, or | |||
* using only one camera and move either the camera or the specimen after capturing the first photo to capture another one at a different point in time. | |||
The special lens is far too expensive for our little project. For the second method, one would need two very tiny cameras or a mirror system to achieve good results. Since we cannot mount cameras and/or mirrors with such a high precision, this approach did not work either. Same holds for the third one. | |||
==== Low-Cost Microscopes for Schools ==== | |||
Today almost every teenager owns a smartphone with a camera on board. Max came up with the idea that it might be really interesting to use this camera with a special mounted lens to have a low-cost microscope for school lessons, particularly in biology teaching. With my old smartphone I just tinkered a little around, but could only try very few lenses lying around with really bad results. However, this idea should definitely be followed in the future with more knowledge about complex lens systems. | |||
==== Making Electricity Visible ==== | |||
This one is quite easy: I wanted to create a spark and view it under the microscope. One could even try to melt sugar to caramel, or burn a piece of paper and record a slow motion video of this process. Unfortunately, I have not found a battery in an appropriate price range that was strong enough to produce a spark that is visible. Maybe this approach can be followed by someone who has an old car battery standing around. | |||
==== Tracking Blobs ==== | |||
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. | |||
