LTSpice newbie

P.S. Where are the .mod files? Also, does LTSpice use them? What are they?

HELP!!!

Hello Jimbo. Please go to this LTspice group:

Read the text on the first page carefully.

First of all always read LTspice help before searching for the answer on the group.

Hello Jimbo,

Transformers in SPICE are done by using two or more inductors and define their coupling ("1" for the ideal tranformer). Look at the very first example "Transformer2.asc".

Play with it, but most of all, read the instructions that come with the help file. Start with "Contents" to learn. If that's too over the top for you at this point I'd suggest to buy a book about SPICE. LTSpice does require some familiarity with circuit simulators. But heck, it is so much easier to learn than the strictly text based SPICE I started with in the 80's.

Thanks for the help guys. Learning all of this software is becoming a full time job in and of itself! Also, the PCB layout program I'm using may drive me to insainity! I guess it's time to start a brewing a few gallons of coffee for this weekend!

Hello Jimbo,

Try Cadsoft Eagle. It's pretty easy, except maybe for the library editor.

I guess it's time to start a brewing a few

Nah, I'd brew a batch of pale ale.

That will be for the Superbowl. Funny that you mention that...me and my dad have been making our own beer. Making some electronics to control the process is next on my to-do list.

If you look around in the Help area, there is an option for printing out the whole manual. 104 pages for the version I printed.

Hello Jimbo,

I used to do that as well, back in college with a few friends. Until that day when we had stacked all the newly filled crates in one of the guys' dorm room. Sometime after midnight PHSSSSST ... KABOOM ... BOOM ... POOF. The Grolsch bottles we used were strong but obviously not strong enough for a bottle fermentation process.

Nice article in the last QEX on inductor modelling with LTSpice. You might visit arrl.org and see if they have the article up as a .PDF; they sometimes do.

It's a shame no one has written an "LTSpice for Dummies" book. There's a wealth of information out there, but it's scattered around in mailing- list archives and poorly-organized docs.
