help for our project we need a pcb layout ready to be printed...needed badly

[xtine0491]

we have a project in our subject this semester, it is a gaming buzzer with seven segment display and a speaker..here is the circuit diagram..what i need is the pcb layout of this one which is ready to be printed..i will attach the diagram..thanks.

Changed my mind - just ignore

If you post your PCB layout for checking thru, someone will help with that, BUT no one is going to do the layout from scratch.

Lets see what you have done so far.

I would do it on vero board.

thank ! i need it badly...help me pls

If you need the PCB design badly you should provide more information, mainly about the switches to be used (manufacturer and type or data sheet). Further I suppose S1 through S8 are individual switches connected to the PCB via cable.

What components are off the board? Do you need connectors? How about some decupling caps?

im just a beginner in this kind of project.. also im not familiar with eagle software which happen to be use for making schematic diagram,,

 

[Boncuk]

No matter if you are familiar with Eagle or not.

Not even answering the questions concerning YOUR design shows me you're not much interested anyway.

I have a PCB layout finished today and will keep it for myself if you don't answer those simple questions.

Boncuk: You are one mean teaser! E

 

[4pyros]

ya but I can see it.

boncuk: only 3 capacitor is needed from the given diagram,, but in your design there are six capacitor...??

You are free to design your own circuit board.

When counting the ICs the result is six.

A decoupling cap for each IC is not a MUST, but good practice. Two decoupling caps seem to be pretty poor to me.

Your critizism is really remarkable considering that you want the board design served on a silver platter and free!

 

[xtine0491]

thanks anyway..i'm just confused of your design... now i understand.. what decoupling caps is.... can i have the design for free>??? thanks...

Sorry I don't understand that. (language barrier).

Even translator software fails.

 

[4pyros]

maybe, whats it worth to you? Do you what free support too?

Boncuk: I believe your native tongue is German:

This was ment in the spirit of pleasant aproval! E

 

[Boncuk]

OK, thanks a lot for the explanation. Now I got it.

Hi xtine0491,

if I had worked the PCB design from your schematic you'd never hear the buzzer.

The BC547 in an NPN-transistor and the symbol is that of a PNP-transistor. So I allowed myself and changed that to BC557 without consulting you. (Beg your pardon )

Here is the image of the revised PCB layout with the reset button underneath the display for easier operation.

Please PM me your email address giving me your full name (for the contact list). I will send you the Eagle files.

Be advised that you cannot apply any changes to the PCB since it's dimensions are larger than the free Eagle version allows.

You can just load the board and prepare to print. You might also create Gerber files.

Hi xtine0491,

here are some screen shots of the circuit.

Note the difference on the 7-segment display with RBI connected to ground and connected to VCC
