In this project, we designed a permanent magnet moving coil galvanometer with parts that are universally available. Our aim was to build a robust prototype that can be used in the lab to demonstrate the working principle of a d'Arsonval galvanometer.
The project won first prize in Instrument Design Challenge 2k15 for EE-221 Measurements and Instrumentation course at CECOS University.
Here is a little teaser of our project.
