I've fixed one problem, in yellow, on the schematic. The PCBs are too small to see properly and seem to be missing a layer?:

You forgot to post the bottom layer. You've shown the top layer twice though.
 
Back to the drawing board

Your ground plane doesn't seem to be connected to anything.:confused:


The original design used one IC 556 I tryed to convert by using two IC 555 the reason I tryed to convert it is could not understand the design.

I will put the disign into the program I use and convert it.

Thank you for your help.

Have included Schematic Diagram for the Chip 556 Timer any help you can give me on this matter would be much appriciated.

You have your tuning capacitor in series with your inductor, which will never work. Go back to having it in parallel.
Your reply to my comment about the ground plane being floating was a non sequitur. You need to connect everything that goes to your negative battery terminal to the ground plane. You won't need to connect this node on the bottom side of the board if you do that. You can use thermal reliefs at each connection.

You are correct I have put the tuning capacitor in series will fix that soon but thank you for letting me know about it that could have been a disaster.

I am still trying to get to grips with the CAD program PCB Wizard 3 as you already know I have not set it up properly that is because I don't know how to if you can help me with setting up CAD program PCB Wizard 3 that would be great I will try and do it myself today.

I need to set up the thermal reliefs on the Pads and different colours for the + rails - rails is there anything else that I need to set up in CAD Program

Thank you for all your help so far


Peter
 
Thank you

Maybe someone else is familiar with PCB Wizard 3.



Could you please look at these designs tell me what you think.


Thank you for all your help it means a lot to me.

A schematic would be helpful.

So what is this supposed to be? Your schematic has two 555s in it, but you have one 14 pin IC in your layout. If you're going to provide a schematic, it needs to match your layout.
You seem to have confused the + and - terminals of your battery.
What kind of transistor is that? Different types have different pinouts.
There is a questionable connection in your schematic (see below). Is it connected, or not?
