Make Your Own!

It’s now possible to make your own spectrometer out of plywood. Just get a piece of 6mm thick wood and download our file. Simple as that! Download our file here.

The Science Fair

Tuesday the 28th, a science fair was held to conclude all projects. Below is an image of our table setup.  On the table the following things were displayed; – A poster shown as on the image below. – A test setup meant for smartphones. – A test setup connected to …

The final two prototypes

We are nearing our deadline so we spent most of today, Monday the 27th, working on our final prototype. Our last prototype consisted of a handmade wooden box without integrated webcam.  Last week we already laser cut the same design that was previously handmade. This already increased the strength and precision …

Results fluoresence spectrometry

Last Thursday we went to the TU Delft ChemLab for fluid testing with a fluoresence spectrometer. The difference between this type of spectrometry and the type we use in our own home made spectrometer can be found in a previous post. Our spectrometer is based on absorption spectrometry, which is …

Homemade Spectrometer Results

Yesterday we went to the TU Delft ChemLab, these results will be posted soon. But we also did some experiments with our own third prototype. We tested the fluids shown on the image below plus a control test: Left image: Tonic, sweet white wine, dry white wine, red wine, Sisi, …

Third prototype

Monday the 20th of October, we started on our third prototype. This prototype is made out of MDF wood and is the basis for a soon to be designed final prototype. We hope the wooden prototype will outperform the paper and cardboard prototypes because of it’s increased strength and precision. …

Visiting the TU Delft ChemLab

Today is the day we will visit the TU Delft ChemLab to test different types of fluids using fluorescence spectrometry. We are eager to find out what the difference is between our “amateuristic” spectrometer and a professional one. Since we will be using fluorescence spectrometry, our sample choice is limited. We have …

Some Background Info

What’s spectrometry?  Colored light is often a blend of different colors. A spectrometer is a device which splits those colors apart, like a prism, and measures the strength of each color. A typical output of a spectrometer looks like this spectrum of the daytime sky, with the actual light spectrum …

First Prototypes

The first prototypes have been made! It is a foldable spectrometer from publiclab.org: http://publiclab.org/wiki/foldable-spec With the instructions on this site we created the following prototypes: Test results are shown under the header ”test results” at the top of this page.
