Nope. An ordinary Cmos inverter or gate won't ocillate with a single resistor and capacitor. You must have used a 4093 Schmitt-trigger Nand gate.

At power up you have to follow next procedure to setup a certain counting mode and divider into the 4059.

1) With no power to the circuit set the 16 jam inputs J1 to J16 at a correct level depending on your divider.
1a) Let say you have a divider of 5070 and want to use the divide by 4 mode.
1b) Calculate the divider to set into the counter: 5070 / 4 = 1267 remainder 2
1c) Jumper setting:
J1: remainder "1" = 0 remainder = 2
J2: remainder "2" = 1
J3: divider "1" * 10E3 = 1 thousands of divider = 1
J4: divider "2" * 10E3 = 0
J5: divider "1" * 10E0 = 1 units of divider = 7
J6: divider "2" * 10E0 = 1
J7: divider "4" * 10E0 = 1
J8: divider "8" * 10E0 = 1
J9: divider "1" * 10E1 = 0 tens of divider = 6
J10: divider "2" * 10E1 = 1
J11: divider "4" * 10E1 = 1
J12: divider "8" * 10E1 = 0
J13: divider "1" * 10E2 = 0 hundreds of divider = 2
J14: divider "2" * 10E2 = 1
J15: divider "4" * 10E2 = 0
J16: divider "8" * 10E2 = 0

2) Set all inputs Ka, Kb and Kc to a low level. Enable the "Master Preset Mode"

3) Apply power to the circuit

4) Apply at least three clock pulses on CP input

5) Set inputs Ka, Kb and Kc at a correct level according to the used "divide by" mode. For divide by 4 mode Ka low, Kb and Kc high

That sequence is implemented by the gates in the "Logic.jpg" file.
Set the 16 jumpers with no power to the circuit, then apply power.
Wire i is low for at least 3 clock pulses from wire g. After that it has a high level setting the counter in de divide by 4 mode.

IC4 makes 50Hz pulses from 24Vac after transformer. That is my counting frequency.
During normal operation I need to count only when there is 24Vdc across D3 but since I need at least 3 pulses to setup the divider I made an OR gate with D4 and D5. Set up via D5, normal operation via D4.

I'm assuming that "Crazy Inventor" is trying to create the circuit for a hydrogen generator coil circuit. I am trying to make this circuit as well. the manual i have has been very descriptive to this point. it simply states that i should connect pin 3 of my 555 timer in my electrode circuit to pin 2 of the 555 timer in my coil circuit by means of a CD4059A divide by n chip.
there is no schematic in the manual showing how to set this chip up at all. it says it needs to be set for "15 kHz - 20 kHz/1000"
i've found the datasheet on this chip, but am still none the wiser as to how to set it up in a circuit.
It looks as though you have already drawn this circuit out, but i'm not sure if you drew it with the specific settings i need. i'm not sure what Vdd or Vss (pins 24 and 12 respectively) stand for.
My electronics expertise branches only from a "basic electronics" class in high school (1993-1994) I can read a schematic- for the most part anyway - and assemble the circuit, but my ability to design... well there is very little of that going on
i understand what the circuit is supposed to do, but i don't know how to set up this chip.

I looked at the jpg on your response and have a good idea about how to assemble it, but i'm not 100% sure about it. which jumpers should i close?

Would you mind helping me with this?
* i'm using a 12-15 Volt supply.
* the frequency going in will be 15 - 20kHz
* The output frequency needs to be 15 - 20Hz (Divide by 1000)
* i already have the CD4059a chip

Thank you for your time

 

The OR gate made with diodes that feed an input of the CD4093 won't work without a pull-down resistor.

I think that should be ok.

 

("From: support@ti.com

Tie pin 24,10,13 and 14 to power. 15V

tie pin 1 to clock 20Khz

the output will come out on pin 23. 20Hz

Tie all other pins to gnd.

The input clock signal must swing lower than 4.5V and higher than 10.5V in order for the part to see it.")


Are you- by chance- working on a hydrogen generator circuit? Just curious because the requirements you described are for the same circuit i'm working on and came to a screeching halt on.

 

Hi everyone,


I found this on the internet on how to program CD4059A for N = 1000

I have enclosed the GIF picture.

Enjoy,

Johnny

have u or any built this circuit yet and does it work?

 

Are you talking about a HHO generator? Well they're very inefficent and worthless as a fuel.
