1959 Tesla Coil

1959OctEIThe young woman shown here is startling and impressing her friends by demonstrating the Tesla coil she constructed according to plans published 60 years ago this month in the October, 1959, issue of Electronics Illustrated. She is shown lighting up a neon tube and fluorescent tube thanks to the high voltage produced by the coil.

The article noted that most Tesla coils presented a problem for storage and transport, since the coil is so large. However, this one solved that problem by making both of the coils removable thanks to color-coded banana plugs. The smaller primary coil had color coded connections, and the larger secondary coil plugged right into the base. After dazzling her friends, she could unplug the coils and easily transport the set to the next location.
