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

Schematic here:
http://open-source-energy.org/rwg42985/russ/The%20Russtic%20WFC%20Frequency%20Generator%20%20v3.1.bmp

  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

Does the 4N35 have a fast enough switching time?
If you want to get it faster take that one:

I have found a fast and cheap optocoupler for voltages up to 1000V.

It has to get a power supply voltage of 5V and that way it´s TTL compatible and really fast.

I took a long look at the schematic and simulating it I would change the following;
- SW1 Connect the Synced pin to COM of sw3 instead of X4.

Also the gating is not synced and that will cost you a mosfet to make synced try this;
- Connect gate ouput to U12 /CLR pin.
- maybe remove U13 and U10 to save 2 chips.

Have to correct myself there was a bit late yesterday, it should be more like this;
- Connect gate ouput to an AND gate input.
- Connect other AND gate input to Q or /Q of U12.
- Connect AND gate output to second AND gate input.
- Connect second AND gate output to U12 /CLR pin.
- Connect second AND gate other input to pull up resistor
- Connect second AND gate other input to gating On/Off switch to ground.
- remove U13 and reuse U10 for and gates.

Or even just connect to gating output to the RST input of the 555 timer U1 but again with and gates of output of U1 so gating is synced.

So gating only begins when signal in in defined state so the 50% duty pulse of main freq will be completed before gating is turning signal on or off.

Hello all,

Just wanted to give a little look at what I have been messing with this week.  :)  I started brushing up on my PCBexpress skills and started laying out Russ' circuit on a Radio Shack sized dual layer board.  I still have a ton of work to do on it, but I'll be posting the file and the part numbers of the components I designed the board around.  I really would feel more comfortable with the design after I bread board one of these circuits. lol  This is my second try at it, the first one got messy. :P I might be done with the design by the end of next week.:cool:

Here's an updated look at the Russtic WFC Freq. Gen PC board.  I still need to "proof read" it to make sure I have everything right.  I also need to get the physical parts so that I can be sure the holes are all in the correct spots.  I'm not sure if I have the correct capacitor size and/or shapes.  Also need to check spacing for the POT's and SPDT switches.  I didn't modify the circuit in any way, and kept with the TIP120 transistor.  I'm sure that might have to change if Russ finds a better way.:D
  I tried to design the board so that all the controls and indicators were on one side of the board.  That way they could be mounted 90 degrees and put directly through a project box with out extra wires.  The SP4T rotary switches can be replaced by a dual row 90 degree 4 pin header, using jumper to select.  I plan on using regular straight header pins with wires soldered to a socket, that will go to any kind of rotary switch.  Otherwise wires could be soldered directly to the board from a rotary switch.
  Does it look like I'm missing anything obvious?  :huh:

Im having to do alot of trouble shooting on my circuit... Found one bad flip flop IC chip.

Seem like I have to add .1uf cap(s) in the power rails between the two 555 chips or else one seems to affect the other

*** Also I have some chips that say DM74LS90N they give me a good signal :) .... If I use the ones that say SN74LS90N things don't work right :(

This may be important.... What chips do you have russ?

CLR = Reset (Clear)
CLK = Clock
PRE = Set
D    = Data
Q    = Output

Some companies use little different naming but functions are the same.
Also the X vs /X means; X=active low & /X=active high.
So note that the 74xx74 in schematic has /PRE active high and the D-flipflop in the simulation is PRE active low so maybe there need an extra inverter or use the other Q as input.

Some some more info and function tables see;

Jep, basicly every chip on the board needs a small cap.
The 555's even needs decouples power like in the lawton circuit, a small resistor to from the Vcc to the Vcc of the 555 and large+small cap to stablelize it so the 555 don't affect the other.

I bought another 7490 Chip today just for fun. Its label is HD74LS90P.... It does NOT work Either

SO.... All good results with the DM74LS90N chip !!
So, I wonder what the difference is, do both have the same pin outs? I used an SN7490AN, they work great, https://www.youtube.com/user/nadingjeff?feature=mhee#p/u/3/3dwonCXH5EI , Jeff.

I have everything working nicely up to the 4N35. Seems like I cant get a clean signal threw the 4N35... kinda like its not switching fast enough or something. Check it out

i am having the same kind of problems...

what is interesting is that Stan's original VIC cards from the GMS did not have opto-couplers... just a 5 amp blocking diode...  but all other circuits that we know of did... this could be part of the fix that helped the system???

see attached photo.

this is a hand sketch i did from the VIC CARD... there is alot of other systems that go in to this... si it may not make sense unless you understand it all. but you can see there is no opto-couplers...  

i have built this circuit, but i have not had the time to get it working properly.

Ha Will, the picture you posted with your switching problem did not come out, all I see is a blank page and your text, is this a schematic or something else, Jeff.
