Wolverton M., Wolverton R. How To Build A Lie Detector, Brain Wave Monitor & Other Secret Parapsychological Electronics Projects - Your passport to the world of the paranormal using everyday electronics

TAB Books, 1981. —310 p.Technical, but approachable, books about fringe science are rare, and this is one of the classics. (Which is one of the reasons it’s hard to find a copy.) And it is very nearly cover-to-cover esoterica. This book features ESP testers, UFO detectors, ley line apparatus, ghostly voice recorders, Kirlian photography, and so much more. (Sadly, there is not an Orgone energy accumulator.)
Not only is each subject accompanied by detailed instructions on building an electronic gadget to experiment with, there is also a historical (and sometimes personal) discussion of the phenomenon. Back in the day (as in, before the internet), this type of information was rare gold.
