Has anyone created an Opto-Coupler Element?
Preferable left handed and right handed.
I am really struggling to use Element Creation !

Re: Optocoupler

hello Robert,

you only have to use the search field of the collections panel and type "opto".

What are your problems by creating elements?

Re: Optocoupler

The issues I had creating an element were two things;
First the 'zoom' function on my iMac was driving me crazy.
Second I was always missing a text called 'tagg'
I gave up in the finish and moved to a PC

I found the Opto-Coupler, its perfect, but its read-only and I need a 'mirror' of it (with the led to the right of the transistor)

Re: Optocoupler

mmm... no idea, I have no mac, I'm on Ubuntu.

Second I was always missing a text called 'tagg'

could you post a screenshot of the dialog?
(in this forum, in order to post an image, you have first to write and post your message, then click on "modify" so that the buttons to upload images appear).

I gave up in the finish and moved to a PC

with Windos or with Linux?

I found the Opto-Coupler, its perfect, but its read-only

DO NOT paste the elmt file I gave you in the QET collection. This collection is marked as read-only because this is the official librairy of QElectroTech.

To edit the elmt file, do the following:

On Windows, open with the windows explorer this path:
[drive]:\Users\[username]\Application Data\qet\elements
Of course, you have to replace [drive] and [username] by the values used
in your system.
paste the elmt file there or in a sub directory you created.

On Linux, open with the file manager this path:
/home/[username]/.qet/elements
paste the elmt file there or in a sub directory you created.

Then start QElectroTech, go to the "collections" panel and open the "User collection".
Double-click the optocoupler to edit it. That's it!

Tip: if you want to have the whole QET collection with read access, copy with your file manager the whole collection into the root folder of the user collection.

you have to create it by yourself. The element editor of QET is really easy to use.
When you are finished with it, you can upload your elmt file in the elements repository so that it is integrated in the official QET collection (in a future release).

But, just need drag and drop all official collection folders into your User collection directly.

You mean this message when trying to save your element?

Re: Optocoupler

Hi...as per my knowledge Selection is more about V ratings and speed than for CTR or current ratings.  Though if you have weak sources, you may want to save a few mA and shop for something with a higher CTR, perhaps even a darlington type. Expect low CTR for faster devices, for a number of reasons.
