Need some help

Hi,

 

I just started with making a PCB, but even after reading "how to's" i still can't figure out how to do it.

 

This is what i want to make, but only with 8 power LED's instead of 4:

So i made this in eagle:

But when i want to make a board i only see this:

 

http://members.ziggo.nl/nl1bzw/PCB1.jpg

 

Can someone help me get started with this?

 

Tnx already.

 

Bart

    Hi Bart,

     

    Firstly, people might be struggling to work out what you are asking here as the actual links above all appear to link to PCB2.jpg even though the text above is correct.

     

    So it looks like nothing is connected in PCB1.jpg and looking back at the schematics in PCB.jpg when looking really closely it looks like the nets are overlapping the LED pin connections. This makes me wonder if things are off grid and not making connections correctly. You can confirm this by trying to move one of the LED's in the schematic. If a net moves with it then it is connected, if not then it's not connected.

     

    If it is not connected as I suspect then do the following.

     

    1) Ensure the grid is set to 0.1" as follows:

     

    grid in <enter>

    grid 0.1 <enter>

     

    2) Move each LED back onto the grid as follows:

     

    move <enter> (or click on the move icon in the toolbar)

    ctrl + left click each LED in turn.

     

    3) Redo all the wiring as follows:

     

    del <enter> (or click on the delete icon the the toolbar)

    click on each net in turn to delete it.

    net <enter> (or click on the net icon in the toolbar)

    click to add new nets as appropriate to reconnect all your LED's.

     

    Best Regards,


    Rachael

    Hi Rachael,

     

    I updated the links, so they should all work fine now. Thanks for mentioning it.

     

    They were not connected as you said. Probably because i'm using centimeters and the objects in the program are made in inches, so i just started a new project.

     

    This is how the project looks right now:

     

    http://members.ziggo.nl/nl1bzw/PCB3.jpg

     

    I couldn't find the same high power led symbol like this in the library list:

     

    http://members.ziggo.nl/nl1bzw/PCB4.jpg

     

    So i used another one from the library list. Does it matter that the symbol crosses the line a bit? I guess this is only the drawing that crosses the line?

     

    And how do i make the copper lines wider? When i change the setting in the top nothing seems to happen.

     

    Thanks already.

     

    Bart
