Workshop on biofilms with Katja Bühler
Workshop Pocket Science Lab (PSLab): Measurements and Robot Controls with Marco Antonio Gutierrez and Mario Behling
Introduction
During this workshop in January, we learned about the PSLab - Pocket Science Lab -, which is an open-source project. A small hardware extension board enables the collection of measurements and data with the phone or PC through different sensors.
PSLab can function as a:
Oscilloscope I Multimeter I Logic Analyzer I Wave Generator I Power Source I Accelerometer I Barometer I Compass I Luxmeter I ...
Sensor experiments
After learning about the functions and possibilities we started experimenting by connecting the PSLab sensors to the PC and giving commands in Python.
coding in Python
We were using the board as an oscilloscope to graphically display varying electrical voltages. For that, we connected two points on the device and changed the script to generate waves with different characteristics.
first setting: the waves are not visible, and the spectrum needs to be adjusted
adjusted waves
measuring two inputs
changing the displayed wave type
comparing the results to a living organism - ourselves-. Displaying the electrical voltages in our fingers.
conclusion
The experiments during the workshop are showing a small piece of the possible measurements with the small device of PSLab. For the results above only one sensor was used out of hundreds of existing options. The device allows us to understand the invisible factors of our environment without a laboratory or expensive devices. It works as a translator between different mediums, the extracted information can be easily converted into an image, video, or sound.
