New, Improved Theremin Mk.2 - This design is an upgrade of our most popular Theremin which was featured in the August 2000 issue. We have added a voicing control, incorporated a larger loudspeaker and increased the power output. We've also changed the power supply to avoid problems with switchmode DC plugpacks.__ SiliconChip One Transistor Theremin - This design is from a magazine called "Divirta-se com a Eletrônica", which translates to "have fun with electronics", and, indeed, is very fun. For those who don't know what a Theremin is, it's one of the first synths ever made and it's named after his inventor, Mr. Leon Theremin (a Russian guy). it's perhaps the only instrument which you don't actually touch: there's an antenna, and as the musician moves his hand near it, the pitch changes. That's the thing Page used in "Whole Lotta Love" (he used it with an echo, to get even weirder). This circuit is a very simplified version of a theremin, but is also very easy to build and really works! __

Theremin for Tube Enthusiasts by Craig Sellen - Nearly everyone who has ever watched television or attended a motion picture has heard music and background effects produced by a Theremin, yet relatively few could recognize the instrument, and fewer still have had the chance to own or play one. With its astounding tonal and dynamic ranges, it has been used to produce background music and special effects in scores of science-fiction, fantasy, horror, and mystery shows __ Designed by C. Sellen
Theremin Model Introduction - Since the publication of the type 144 theremin project article in September, 1998, many of them have been successfully constructed. As in the 144, and its forerunner, the Southwest Technical Products model 142, the 145 theremin retains a heterodyne topology similar to that used by Mr. Theremin in his original instruments.

Wien-bridge Theremin - This circuit is a basic theremin with only a pitch control. it uses the "heterodyne" technique, as did Theremin's original instrument. Heterodyning is advantageous in its simplicity, and is made further attractive in this design by eliminating the coils that are usually hard to find (electronic design 10/05) __ Designed by Arthur Harrison |
