ProFPGA Banned Feb 18, 2015 #1 Hi All, have any one worked on or studied derive circuit for a PIG or PIG Signalers , these are used to inspect gas/oil pipelines , these are inserted into pipelines . they either maintain a constant magnetic field around them or produce pulsating field . I want to build one and make its circuit . see pics attached Thanks
