Abstract

A modern low cost microcomputer and accessories were used to create a very low frequency (VLF) receiver for geophysical prospecting. The signals were detected by induction coils, which were then amplified, digitized by a sound card, and analyzed by a Raspberry Pi computer. The computer used a Linux operating system and the Python programming language. The peripheral devices were "off-the-shelf" commercial items except for the preamplifiers and the induction coils, which were designed and constructed by the authors. A test profile showed typical VLF anomalies across a weak conductor.
