Missing components in the library...

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 order all the coponents for m digikey (got an head acke with their web tool..)

 

My coponents are:

• SN74ACC14N: Found it sounds good

• EVU-F3lFL3B14 (potentiometer): even wiht the datacheet I do not find it

 

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.

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...)

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.

Just a comment from a guy who does electronics design for >25 years:

Packaging, component selection and the creation of library parts is

boring but it is often 50% of the job. Especially on cost critical

designs. So it is very important to learn the library editor of a new

CAD system very soon. Eagle isn't particularly easy to learn in that

respect but with persistence you'll get there.

Afterwards, when you haven't used the program for a while it is normal

to forget things.

By the way, the Digikey search engine is hands down the best there is,

there ever was. If you learn how to use that (easy) it becomes a

wonderful tool to find electronic parts. And now they also let you sort

by price.

But I will get at it then...

 

En peu du vin rouge, du fromage et la bonne musique ... and it will all

come together nicely

Thank you Joerg.

Quoi comme frommage, un chevre par exemple? le boursin ne me dit rien pour l electronique...

I have been able to create my two first items in my library (thanks to kd7vnn http://www.instructables.com/id/How-to-make-a-custom-library-part-in-Eagle-CAD-too/).

I undertsand what you say about 50% of the job but when you are just doing it once in a while it is a bruden... but it is ok.

Now that I here one more question: Why do I struggle so much to have a connection between my wire and my components? one time out of two it does not requognize each other... is there a parameter to make that more automatique?

Maybe your component is off the grid and you have to press "Alt" for the

alternate grid. I had some unconnected components due to this when I

first started using Eagle.

Hi Alex,

I know making components in the library can be a pain. Have you tried

out the make-device-package-symbol-bsdl.ulp included with EAGLE? It

doesn't do everything but can speed up the process of creating ICs and such.

Maybe it's worth a look.
