Free Circuit Simulation Software

Just though I should point all the DIYers on this forum to this piece of software
Yenka
It's a
good free (for home use) circuit simulation software. Great for testing out simple
circuits and microcontrollers.
It's basically a new version of the Croccodile Clips
software that I used at school and it is very realistic.
As I have said before the
home licence is FREE (the only limitation is that it cannot be used between i think 9:00
and 3:00 weekdays (to prevent schools form just using the free version).
It also
does other things such as science sims Etc. but I think that the electronic circuits sim
will be most useful (even does PCB's too! if I remember correctly)
To
download go to http://www.yenka.com/en/Free_home_licences/
Works on PC,
Linux AND Mac!

Yes is quite useful, especially when you blow something up!
Also the fact that you
can have Mega Volt batteries!
Used the previous generation software crocodile clips
at school and when I found I could get it for free I was well chuffed!

Try also LTSpice from linear technology, IMHO a better simulator.
Got to be a
little careful with simulations, they are only ever as good as the parasitics you set up.

I've also installed — but not yet checked out — Circuit Lab (circuitlab.com) which is
a free app extension for Google Chrome. DroidTesla for Android is also worth checking out,
though a bit fiddly on a mobile screen...

I just use a notebook for the electronic design process and a breadboard to try it out
 I can see the attraction of a virtual design process though, especially where
expensive components are involved  Martin

That's fine Martin, but you try say calculating the noise spectrum of a multiple feedback
filter that way......
Spice should never be allowed to over rule common sense,
but it does have its place.

I must say I'm another bread boarder. Most of the stuff I do is pretty simple and I can
usually have an idea working and tested in a few minutes. Also I frequently take delight
in using obscure features of components. Last time I used a simulator (admittedly quite
some time ago) it failed miserably to account for this. One of my 'classics' is
this little beastie. For anyone who's interested, the prototype
used BC108s and I made the point that C2 must be low leakage (that meant Tantalum in those
days) and you should not fit a supply decoupler. P.S. An alkaline
PP3 lasts up to 2 years  P.P.S. Warning: SVG file. Some {cough} inferior browsers can't display it.

It doesn't have simulation tied in, but TinyCAD is a good schematic editor.

I've got several hundred of the things still boxed away, although it was always the
BC109D that got everyone excited for its higher gain and lower noise

What is rather amazing is that these are still listed as 'current' types unlike many of
their, um, replacements

I wonder if that could be because of the retro brigade still copying 1970 stomp box
designs and searching for germanium transistors for better 'tone'?
