Interesting website
« on: December 19, 2008, 04:12:19 AM »
I thought this might be useful for some of the newbies,and even some of the pro's. (make sure you have Java enabled.)  You can change component values and all of that fun stuff.

Wow,


Very useful indeed for the electronically challenged which includes myself. Plus no sign up required, no b.s. I will be using this tool to design my booster circuit a la "Flux".


Thanks for posting much appreciated.

Absolutely - It's like SPICE on steroids! Excellent find!

Ive done some somewhat lengthy experimenting with this thing today.


Props to the author! Best I've seen in a while. It's got the typical SPICE-like issues, and has room for improvement in a few ways, but very useful and definitely entertaining. What a way to blow a few hours!


The cool part about this is, with the export feature, we could share not only schematics, but visually share some of the theories behind what we are thinking for a given idea, right here in the posts (its in text format).


A few heads up that I noticed that aren't made really clear on the web site:


Import/Export seems to require Shift/Ctrl Insert respectively. Right click (at least for me) to copy and paste doesn't work.


Don't close the browser if you use the main applet, it will exit without a clue and you'll lose whatever you haven't exported.


I still have yet to see a SPICE modeler that can accurately handle certain oscillators very well, this one is no exception. They usually involve a transformer; a simple hartley confuses it.


Anyway, like I said, this looks like fun! Can't wait to see what you guys come up with...

This is both fun and easy to use.  Now I have one more toy to play with over Christmas vacation!


Attached below is the code I just exported.  If you were to go to the www.falstad.com site and open the Java applet, you could select "import", copy-paste this into it, and you will instantly see my circuit running!


(PS for anyone posting their JavaCircuit code like this, I suggest looking carefully at the forum's posting options, and selecting "plain text" format instead of the default "autoformat".  This will prevent the forum's software from doing "helpful" things to your code.)

No one believes the theory except the one who developed it. Everyone believes the experiment except the one who ran it.
