a 150 components circuit schematic

[mona:)]

Hi everybody;
I need a circuit schematic with at least 150 components to capture it to Altium designer to make its pcb layout. I looked for it in net but there is no more than 50 components.
Thanks
mona

p.s: its beter to be contained resistors & caps & teransistors & diod which have more common footprints

Would 1247 components be enough? https://www.transistorclock.com/
You could make somehting similar, say a counter from transistors, all the blocks should be in that manual.
Or a 10x10 matrix LED display that graphs volume in frequency bands or something similar could fit the bill.

first of all thank u, but dear its to much components ,I am beginner with altium ,how to drag and design components on board……

 

[kubeek]

So why does it have to be 150 components? And please stop using text speak and use sentences, paragraphs etc, this is hard to read.

 

[mona:)]

so actually, it’s what my professor has said. It is a project for us to learn how to use altium designer to make a pcb board. It’s dead line is Saturday…. but that circuit was so interesting thank you.

 

[kubeek]

This saturday is deadline to choosethe circuit, or a deadline to make the pcb?

 

[mona:)]

yes i am so poor the second one is correct ,deadline is for make it's pcb board ....

 

[kubeek]

Then you'd better choose the circuit today.. Does it have to be a working circuit, or can it be just anything and the layout is the important thing?

 

[mona:)]

the layout is important as i mentioned it's for learning .

So have a look at this: https://forum.allaboutcircuits.com/showthread.php?t=16553#post102267
If you duplicate it 9 or 10 times with different band pass filter values all connecting to one singal source, then it will make ~180 parts + power supply, and stil be a meaningful design.
EDIT: note the two wires going from the filter need to be swapped, so output of opamp goes to pin 5 and the other goes to pin 4.

i couldn't find any circuit in above link. could u attach it

[mona:)]

there is no easier way?

 

[kubeek]

Easier way to what?
EDIT: well if you can get away just with connecting 150 resistors together and calling it a heating circuit, then why are you doing all this exercise with trying to find a schematic?
What i posted is as simple as it can be while still doing something that isn't complete bollocks.

 

[mona:)]

no i mean i want something like 741....i didn't get what you said about duplication...

 

[kubeek]

I meant that you draw that circuit 10 times and then make the pcb. The two wires going to the "signal source" will be all connected together.

It is up to you to decide what you need to do, and I doubt there is any schematic with 741 or other opamps that is readily available and has more than 150 components.

thank you i think i got.
