hi, could anyone suggest from where do i download free software for drawing circuit diagrams on the cmptr instead of having to draw them on paper and scan them for sharing it with someone? i tried 'smartdraw'. but it does not get downloaded, though the web site claims it. thanx.

Several CAD packages have free evaluation versions that are limited say to a certain number of components.
Orcad for example has a limit of 50 components IIRC.

This sounds like a question better suited to sci.electronics.basics. Your IM-speak assures it.

Here is a site that has free, presumedly unlimited software:

The schematics drawing software is part of the package.

Writing stuff like i, cct, cmptr, thanx, posting from Google Groups, and not being able to find a free schematic editor all go very well hand in hand.

They also go in hand with him being a young Indian.

I like ExpressPCB's schematics. Free, easy to use, and look good. Easy to make your own components. I use it for documentation, even when I'm not doing a board. They can also be exported as a 300 DPI bitmap, if I want to remove their stock frame.

Robert, you andJeff probably should try some exlax and maybe you will feel a litttle less grumpy. ;)
Actually I suspect they do better in Indiana than in California.

Pardon ! ?
I already gave you a good link for Orcad.
What's your problem ?

Just use the schematic capture part.
Google "cad freeware".

No, no, no - PLEASE don't encourage people to use nasty closed programs of this type. The sole purpose of that software is to tie people to that particular PCB vendor.
I agree with Lewin. If folks are going to recommend this Lock-in-ware, at least have the decency to point him to a page that shows the hoops you have to jump thru to get hard copies.
I find ExpressPCB rather economical for one-offs.
Not really that hard...
If you have PaintShopPro:
(1) Print desired layer to a file using a *color* Postscript printer driver (I installed a Tektronix 780 Graphic printer in Win2K). (2) Bring into PaintShopPro (at 300/inch) (3) "Posterize" the image (4) Using "Magic Wand" tool select one piece of trace (5) Selections > Modify > Select similar. This will select all instances of that color on the image. (6) You can then copy and past that selected content. (6a) You may need to "Resize" the image to make it actual size. (7) Save as desired file-type.

I love to cook with wine. Sometimes I even put it in the food.

Straightforward, small, clean. Lots of predrawn components and minimal PCB baggage. john
