Back at the parish, Diviš became responsible for the management of farmland belonging to it. He undertook the construction of water conduits on the property. As a result, he became interested in a popular new interest in the scientific community of his day, electricity. He began a series of experiments over the next years, mostly on plant growth and therapy with small electrical voltage. He published the results and allegedly demonstrated at the Imperial Court in Vienna. Diviš also constructed the Denis d'or, which allegedly imitated the sounds of various musical instruments. This instrument is dated to 1753, though only one prototype was built, and it vanished soon after Diviš death. The novelty instrument produced electrical shocks as practical jokes on the player. It is disputed whether the Denis d'or sounds were also produced by electricity or if it was an otherwise acoustical instrument.
