Abstract:In this project the goal was to improve the bug zapper that Ruud van Laar and Martijn van der Ouderaa started with. The sound localisation had to be improved and the laser had to be implemented. The sound localisation is still done by five microphones, with one of them as reference microphone. We improved the set-up by changing the positioning of the microphones. The average error in the xdirection is 1.1 cm (maximum 3.5 cm), in the y-direction it is 0.6 cm (maximum 2.6 cm) and in the zdirection it is 1.0 cm (maximum 2.4 cm). The measurable space is approximately spherical, with a diameter of 15-20 cm. The calculation time is a 130 times faster, which is mainly due to the substitution of the Matlabnodes by Labview functions and a shorter sample length. The laser is controlled with a two-axis galvano-system. The combining of these two parts is simple, the output from the sound localisation is the input for the galvano-system. The total success rate of our device is 85%, which means that only 15% of the mosquitoes that fly through the measurable space will survive.
