Re: [TCML] 24 Issues of "The Electrical Experimenter" are now available online

Volume 6, Number 11 (March 1919) has an interesting article on Tesla's "Egg of Columbus" rotating-magnetic-field demonstrater. I'd never seen any info on the frequency Tesla used to drive the two-phase winding, but the article states that it worked best at 35-40 Hz (although it had been tested from 25-300 Hz.).
 
Also shown in this article is a photo of Tesla's Houston Street laboratory with a large portable "Tesla resonant transformer primary" that "collected" energy from an "oscillatory circuit" that surrounded the entire lab.  A one or two turn "secondary" coupled to this coil provided power to lamps, motors, vacuum tubes, and other devices. I'd not heard of this setup previously.

Hi all,

Twenty four issues of Hugo Gernsback's "The Electrical Experimenter" magazine are now available online at the Archive.org website. These issues make an incomplete set that goes from May 1917 to June 1919. They can be downloaded in a variety of formats including PDF.

The issues include a number of articles authored by Tesla in Aug 1917, and his five-part series, "My Inventions" in the Feb - June 1919 issues. Articles about Tesla's Wardenclyffe tower being dynamited by the US government (Sept 1917) and Tesla's "pointless" lightning rod (Oct 1918), and "Egg of Columbus" (Mar 1919) are also included. Lots of other interesting articles from the period as well as fascinating scientific speculation.

As you probably know, these magazines have become virtually impossible to locate, and the few that remain command exorbitant prices. Thanks to Bill Beaty for discovering and passing this along in a Usenet forum. I've shortened the URL to make it easier for TCML'ers to link to:
