Hi Doug,

For simulation of analog circuits, there is a very nice (and free) version of Spice at:
http://www.penzar.com/

This is a very user friendly program and it's good for getting a feel for how circuits operate.
You can plot the currents and voltages versus time and also do frequency plots.

For drawing schematics and laying out small pc boards, a useful and also free program is at:
www.expresspcb.com

Has anyone used an electronic circuit design software package?  I am mainly interested in being
able to draw decent schematics, but
have noted that there are several packages that seem able to emulate some circuitry.  I am
relatively inexperienced and would like
to learn more about solid state digital and analog circuits.  My latest electronic training was in
1968 where learned all about
tube-based television circuits.  Not very useful today.  I was also thinking of buying one of
those electronics trainers where you
can do hundreds of experiments.  Thought it might be a good way to get exposed to the "new" stuff.
Does anyone have any thoughts on
those?  Ramsey sells some nice ones. (http://www.ramseyelectronics.com)

Building the K2 and K1 and a variety of the add-ons was a great experience and wetted my
long-dormant appetite for experimenting
with electronics.

Thanks in advance for any opinions shared.

Hi Doug,

The freebies/cheapies are ok to start out with. However if you get serious
(eg more than about 50 connection points) you will need something with good
functionality. I use EDS 3.1 Advance which is extemely functional,  has good
routing capability and includes copper pour which is nowadays almost
essential for minimising RF noise. It also has spice capability which I
admit I have not used much as I mostly do digital embedded controller stuff.

Regards,

Tony

Just have to voice my opinon on this one.  Eagle is very impressive.  Just
laid out a few components in a project and it works great.  And lots of
components in the library.  A great recomemendation.  Thanks to all.
