Missing components in the library...

Former Member

Hello,

Still using the free version and still at newby silly question level.

I am creating (at least trying to) my first PCB board which is going to be a PMW. I started by ordering all the coponents from digikey (got an head acke with their web tool..)

 

My coponents are in my ordering list:

* SN74ACC14N: Found it sounds good

* EVU-F3lFL3B14 (potentiometer): even with the datacheet I do not find it

* 1N5817 (diode): can not find it... 9there is of course some close enough)

* BUL704 (NPN) was not able to find it directly but using the number of the datasheet TO-220 whihc was not in the database either I end up finding it using TO220...

* 1N914BTR (diode) was not able to find it... (same thing found stuff close enough after some time but my electronic level is limited)

 

And the list is going a like that on every conponent.

My frustration level in rising, I spent more time looking ofr the components that I will spend on creating the board (step that I have note reached yet...)

 

 

So simple questions:

1) I am doing something wrong?

2) If I am not doing anything wrong where can I find an extended library of components?

3) If netheir one or two are possible, how do you proceed on your side to order components? you try to see if they exist in Eagle then in DIgikey (for example) and then only order them?

 

Thank you for your help

    Sorry, no email adress to send the extended lbr.

     

     

    • 1N5817 (diode): can not find it...

     

    Use diode.lbr -> device DIODE- with package variant DO41-10 and set the

    VALUE to 1N5817.

     

     

    • BUL704 (NPN) was not able to find it directly but using the number of the datasheet TO-220 whihc was not in the database either I end up finding it using TO220...

     

    Use transistor.lbr -> device *-NPN- with package variant TO220 and set

    the VALUE to BUL704.

     

    • 1N914BTR (diode) was not able to find it...

     

    Use diode.lbr -> device DIODE- with package variant DO35-10 and set the

    VALUE to 1N914BTR.

     

     

    And the list is going and going like that on every conponent.

    Thank you both for your answers.

    My mail adress is abessy@free.fr ;-)


    I was hoping to spend more time to design the PCB and less on the components selection but I understand that all of them can not exists. It is just hard from the point of view that I am not doing PCB often (in fact it is the first) nor I am working in the electronic field so I am not fluent with the components equivalence (yet).

     

    But I will get at it then...

     

    Thank you again for your answers.

    Thank you all for your help.

     

    Marius: I will try it right away.

     

    Gary: For the grid being french I went for mm which is may be not wise with some of the existing components of the library.

    My circuits are going to be home made (at least the first few to see if I can do something by myself) so coarse is ok for now. I will remember it for next time.

     

    Jorge: I have not tried yet and I will.

     

    Joerg: I am sad (but also veyr happy) to say that I am currently living in the US and undertsand perfectly what you mean concerning the cheese!!! Trust me...

    I keep struggling but sure for no reason I must be doing something wrond becasue a component as simple as a resistor gives me issues:

    [IMG]http://i203.photobucket.com/albums/aa14/badbad214/Eagle/R1_Position2.jpg[/IMG]

     

    [IMG]http://i203.photobucket.com/albums/aa14/badbad214/Eagle/R1_Position1.jpg[/IMG]

    As you can see my resistor (that I picked from the library) is oscillating between two posiitons AROUND the grid... I think that I have the snap on the grid function activated (I did Grid On command but not sure if it is the right one). I tried to move the component using the Alt but it does not stop right on the grid and the connection does not create itself. I did not chage the size of the grid...

    Hold the CTL  key down when you select the resistor. It will snap the

    resistor to your 0.1 grid

    Back on business Thank you Warren.

     

    Another question (tell em if I need a new post by the way):

    when I run the check I get warning on wires close but unconnected:

    http://i203.photobucket.com/albums/aa14/badbad214/Eagle/WiresNotConnected.jpg

     

    The fact that I put a junction should not have fixed the issue?

    as an example:

    on this component from the library how do you know if the pin and gates are numbered as in the datasheet of the component?

    SET PAD ON or OFF

    or go to Options/Set/Misc menu and look for "Display pad names".

    Costco often carries Boursin, the three-packs with different flavors.

    Occasionally they have a Camembert that's actually fairly good if left

    outside the fridge for an hour or so. But not very often image

     

    World Market and Trader Joe's are also good places to hunt for tasty

    European cheeses, if you have those store in your area. Bread is another

    story and we sometimes bake our own, in the barbecue.

    always bake my own.

     

    @OP: lay out your board in mm if you wish ( I often do ),

    but keep schematics at 0.100".

    Very good. We also bake our pizza in the barbecue, over charcoal. Most

    of the time coals from real firewood. Even when it hails.

    Yes, except for library symbols. In order for the more complicated ones

    to look good it is important to switch the grid down to 0.025" or so.

    But make sure outlines and pins are on the 0.100" grid.
