Graphics
Content
Here you can find some graphics that I have created for various purposes. You can use them for your own projects, because I have released them under the GNU GPL. The graphics are provided in PNG and SVG format.
A doorbell
This is a doorbell I made for a card on which my girl-friend and I gave out our new address. You can change the name in Inkscape, it is a text-object. Download: SVG - PNG.
LASER: Medium, resonator and FPI
The first picture shows the combined effect of the resonances of the LASER-medium (red) and the resonator (green) which produce the possible longitudinal modes (blue). The second picture shows the schematic result of scanning this LASER with an FPI, as seen on an oscilloscope. Both images were created with GNUPLOT. You can also download the GNUPLOT-script that was used to create them. The script is commented, so you can easily see how it works.

A capacitive humidity sensor
A thin plastic-foil with a thin, porous gold-layer on each side. Water from the environment goes into the plastic and changes the dielectricity and thus the capacity of the sensor. When used in an oscillator, the presence of water will change the output-frequency. Download: SVG - PNG.
