    ok friends i need help whith building a square wave presicion oscillator,brainwaves,theta 3.5hz,6.3hz,alpha 7.83hz,7.0hz 10.0hz,betha 14.1hz,dave jhonnson sugest to use a LTC1799 IC and then a divider CD4020 I WANT TO USE A 6 position sw to switch from frecuencies,:confused::confused:any good help it is 4 my new chi generator:D:D:D thanks to all have a great one

    Hello,

    How accurate do you want the frequencies to be?
    Can the 7.0 Hz be derived from the 14.1?
    This would give 7.05 Hz.
    And the 3.5 Hz?
    This would give 3.525 Hz.

    And what do you want to connect to this precession oscillator?

    Can't see how those frequencies would generate one.

    a chi generator,or more simple life force energy,im planing to do deep maditation,when listening this tones pasing this sounds thru mi orgonite chi generator,but not all people can design this multiple oscillator ,it need a good knoledge,of electronics it is a presicion square wave oscillator:confused::confused:

    Hello,

    The LT1799 uses a resistor to set the frequency.
    The accuracy is about 1.5 % (according to the feature list).

    I also attached the complete datasheet.

    How can you be sure that one of the six you choose will help you. Every living thing responds slightly differently to different waves. If you use 3.3hz 3.9hz 4.1hz 5.8hz 6hz and 7.8hz as your 6 selections, but your brain and body just so happens to only respond to 3.45hz? You dont have that available on you 6 selector switch.

    Actually, you should use a pot, rather than a selector so you can achieve every frequency in between
