I have a small circuit on file but am unable to open it into the editor. I have firefox on my system as well. The circuit is public. What am I doing wrong?

Try that blue button that says "open in editor".

You will be presented a screen with space to draw on the right and an array of parts on the left. Click which part you want and place it on the drawing area. Investigate the menu items to discover the options you are allowed.

It may take a bit of time, just like any tool, to get the "feel" of it. It helps a lot if you have had experience with schematic capture tools before.

I would suggest you get a book or friend that has run SPICE simulations if you want to simulate stuff here. The SPICE syntax is pretty standard - so if you ever messed with one, this one is pretty standard.

It took me a few hours messing with this tool before feeling comfortable with it. Thats why the authors of this tool gave us the ability to make our circuits public. Quite a few of us have placed little snippets out for others to play with,

Play with a public one or two and get a feel of what we did to make it work - move some parts around - make and break a few connections and get a feel for this thing... and when you feel comfortable - open your own up in the editor.

You were trying to post a jfet amp? I have a public one you might wanna play with - it simulates as well.

Go ahead and play with it - you will get a copy to play with - and you can do anything you want with it. Me ( and the CircuitLab people ) are the only ones who can change or delete the original.

The guys who made this site in my mind are geniuses. Its a great playground for us circuit freaks.

I have Firefox too. Ver 8.01. You probably need Java on. Hopefully one of the masters of this site read this and fill you in if you still having problems.

Guess what... I just opened up to create a new circuit and I got that JavaScript required page!

I may have misunderstood your request as I saw you had posted a blank drawing and thought you may be having "newbie problems". FWIW, I got nailed too... I am a little loathe right now to say too much because I just finished installing a slew of Microsoft updates and sometimes my machine is quite unpredictable after a diet of these..

I checked,,, my JavaScript is enabled. I opened up an existing drawing no problem.. then CircuitLab let me create a new drawing. Maybe you stumbled onto a bug. Watch what you do and see if you can create a sequence of events that makes this repeatable. Things like this can get hard to trace until a way of making them show up is found.

Hi Anubi. Many tnx for your insight. getting a response to a querey is heart warming and encouraging. all around. I must be really doing a lot wrong for you to only get a blank page. and there maybe one problem. One spice programme I have played with was Tina, I couldn't fathom out how run simulations on it at all. I'll try and redraw the circuit and post. Hopelfully it will show up this time.

Tnx again..

Good Lord!

After all the respect I have had for TI , I read this?!!?!?

It made me sick to my stomach to see something like that in print.

I had always thought of "TI" and "top-quality cutting-edge high tech" in the same thought. TI has done such a great job making graphing calculators for teaching math in schools.

After this, I think of them like the RIAA trying to make sure none of their artists are seen on the internet. In my day, the "labels" were desperate to get their artists worldwide exposure on the "Ed Sullivan Show", "American Bandstand", and of course played often by every town's local DJ. So desperate they would buy the station to insure they could guarantee airplay.

Wasn't it UCBerkeley, funded by the public, which coded Spice in the first place, and wasn't it the public who funded TI through government contracts, and they do this?

I guess this kind of thinking is why I no longer think "TI" and "linear" in the same thought; instead "Linear Technology" and Maxim immediately comes to mind.

Sorry for using the CL forum to vent, but I had to say something.

Although I do not "teach" per se, I am always open to mentoring some youngun build stuff and understand what he is doing. Anything from refrigeration to robotics to RF modems. I am in my 60's and a bit old to be considered as an employee in this field, but if a kid has a burning curiosity as I do, I'll show him the ropes and share the tools I have collected.

I have been very interested in this site and will study it, so that I can use it show one of the neighborhood kids how to design circuits.
