free electronic circuit simulator

[koffijunior]

does anybody know a free electronic circuit simulator and can help me test my circuits?

LTSpice

I have posted hundreds of running LTSpice circuit simulations on these forums (and others).

I also use LTspice.
It's probably one of the best free circuit simulators available.
It has a somewhat steep learning curve, but it's well worth the effort if you are designing circuits and/or learning about electronics.
It finds a lot of circuit errors before you built your breadboard.
LTspice has some good tutorials and many sample circuits to help you get started.

I third the LTspice suggestion.

Fourth.

Just keep in mind that you will likely need to create a lot of models yourself, or at the very least import them from third-party sources. By default LTSpice mostly only contains Linear Technology components and a few other standard parts. But chances are you'll need to import your own models for a lot of circuits.

thanks. any tutorial to help me?

thanks. any tutorial to help me?

Besides the "official" ones, those by Simon Bramble will show you how the basics work.

i have a nice ltspice constant power load here...

Also here is a useful voltage controlled switch, for when you want your sim to turn something on or off at a specific time

and some quik start guides

and a nice nand latch using logic components

just get into it and start your sim.....dont be like me and be afraid of starting it because you somehow convince yourself that the PC will blow up if i mis-wired something

I attended the Del Mar Electronics show this week. There was an Analog Devices/ Linear Tech booth. I asked about LTspice and the convergence of AD parts with LTC parts. I was informed this was in the works. This convergence should add a large amount of component coverage in LT Spice which will make this free tool just the more valuable
