Hello everyone,

Test. Test. Test.

This is my version of Stan's frequency generator.

(See Attachment)

I have giving it the name “The Russtic WFC Frequency Generator” just for fun so we can call it “the Rustic circuit” for short.

This is basically a dual circuit consisting of some 555 timer’s and some divide by 10 chips with a d flip flop for true 50% duty cycle switching. With an and gate for combining the signals for gating.

I have included some information I have done while building this circuit…

I’m posting this some what un finished. The circuit will work as is, but I would like to ad some MOSFET drivers and some inverted outputs so I can run the GHH and EEC.

I will add that as I go.

Any suggestions are welcome.

Once all is done I would like to make some PCB so this can be nice and neat.

Enjoy,

~Russ

Some calculations for the The Russtic WFC Frequency Generator (True 50% Duty Frequency Generator W GatingV3.1 ) Schematic

Here you will find the calculations I maid while building this frequency generator. It may be of some help so I added it to the files.

The 555 timer will run at a frequency of 19.894khz to 220.845khz with a .33nF capacitor.

The 555 timer will run at a frequency of 1.989khz to 22.084khz with a 3.3nF capacitor.

The 555 timer will run at a frequency of about 198.941hz to 2.208khz with a 33nF capacitor.

This means I can get from .099hz up to 110.422khz frequency with this a 50% duty with the 74LS74 and the 74LS90 IC’s. Using these deferent capacitors, 33uf , 3.3uf ,.33uf

Here are the Minimum and Maximum values.

Max Values With a .33nF 74LS74 and the 74LS90 IC’s

220.845khz / 2 = 110.422khz /10 = 11.042khz / 10 = 1.104khz / 10 = 110.422hz

Minimum Values With a .33nF 74LS74 and the 74LS90 IC’s

19.894khz / 2 = 9.947khz /10 = 994.7hz / 10 = 99.47hz / 10 = 9.947hz

Max Values With a 3.3nF 74LS74 and the 74LS90 IC’s

22.084khz / 2 = 11.042khz / 10 = 1.1042khz / 10 = 110.42hz /10 = 11.042hz

Minimum Values With a 3.3nF 74LS74 and the 74LS90 IC’s

1.989khz / 2 = 994.5hz / 10 = 99.45hz / 10 = 9.945hz /10 = .9945hz

Max Values With a 33nF 74LS74 and the 74LS90 IC’s

2.208khz / 2 = 1.104hz / 10 = 110.4hz / 10 = 11.04hz / 10 = 1.104

Minimum Values With a 33nF 74LS74 and the 74LS90 IC’s

198.941hz / 2 = 99.470hz / 10 = 9.947hz / 10 = .9947hz / 10 = .09947

So if you need lower or higher Hz for your cell you can change the capacitor selector.

But this should cover anything you will need
