Does anyone know of a freeware program which can create electronic
schematics?

Thanks.

Electronic Design Studio Version 3 Freeware
03/01/02 9x-ME-NT-2K-XP
Publisher's Home Page Setup & Uninstall 9340kb EXE File

Electronic Design Studio 3 is an integrated EDA. The project and netlist
navigators let you move around your project easily, and the comprehensive
range of tools including the fast powerful Viper II autorouter, and new DTM
mean that you can spend less time swapping between packages and more time
designing. Other features include hierarchical schematics, integrated
SPICE/XSPICE simulation, CADCAM, active shape based copper pour zones,
realtime DRC, online connectivity, advanced Polyblend and shaping tools and
a totally customisable user interface. The built in project wizard also
makes starting new projects easy, creating all the necessary documents,
importing and capturing netlists and then generating a PCB document with
the board size required. Once this is done, creating schematics in EDS
couldn’t be easier. Drag and drop symbols into documents from the browser,
and wire them using the automatic 'follow me' wiring tools. Simple.

It depends a little on what you need it for.

The short answer is to download a freeware spice simulator which include
schematics capture.
Then you can not only draw schematics, you can start a simulation and see
what happens if you had built it and turned on the power.

The spice simulators which are available are many, and it is not easy to
recommend any definitive best choice.
I use Electronics Workbench version 5c, the last version before EWB changed
to a buggy new engine and changed name of the company.
But that program is not so easy to get hold of anymore.
That is the best for beginners though.

The easiest to download and start using is Switchercad III.
It is the fastest and most modern spice simulator, but it is not so easy
and intuitive to work with.

If your needs are different, maybe you want a way to produce beutiful
schematics for showing on a web page you can use any paint program and get
a library of symbols somewhere.
The disadvantage with this solution is that the program has no electronics
intelligence, the wires do not follow when you drag a component to a new
position as they do in a spice simulator.

If you want to create ascii schematics you can use a freeware program like
http://www.tech-chat.de/AAcircuit.html
It is used to show shematics in text-only electronics newsgroups.

If you need more help you can ask in sci.electronics.basic
There are always a lot of helpful experts there.

Was it this one:

Doesn't matter. The site is under development and it doesn't look like
freeware.

I was hoping to find a freeware version of this one, but unfortunately
there isn't one, just demos.

Thanks for all the great info. I download the SwitcherCad program you
suggested. It's a bit over my head at the moment, and the help isn't
all that explicit about how to do stuff...I may just have to mess with
it a bunch until I can get an understanding of how it works.

Take care.
