To handle our family of 20 for Thanksgiving I made an extra table from
4'x8'x3/4" oak plywood, and finished the edges with some solid oak
trim.
This sits on top of a standard Costco 30"x72" folding table (alignment

Is there any SPICE model for a TIP102 darlington transistor?
Thanks!!

Title says it all, really... I want to have a couple of interconnected
monostables but am not at all sure how to do it... I may be missing
the obvious...
Any ideas gratefully received...

I am having problems to simulate a well known circuit
(astable) with CircuitMaker. I include the CKT file,
could someone tell me why the simulation does not work ?
Here is the file.

   I have a 0.8mm pitch BGA device to be routed. It has 256 balls
arranged as three rows on the periphery and all ground and a few
signal pins inside. I have ample space on the board to fanout. I have
arranged an array of free via matrix around the device and assigned

Does anyone know which program can create a schematic
like this one:

thanks,

I've downloaded the demo of Micro-Cap 7. Great program.
But now, I have a doubt: I've added more models to the libraries,
and would like to have my models show in the menus. Is that possible?
And I have an op-amp model that uses the pinout: + - OUT V+ V-, how do

In case anyone is interested,  I have just released a 'Carbon'
version of MacSpice. The interface has had a major overhaul [*],
it runs native (aqua) on Mac OS X and is compatible back to OS 8.6,
and it's still free:

Mike,
Any chance of adding Eagle support to your list of supported netlist exports... ?
Thanks,

I need to simulate a simple analog circuit which has a led,
an scr, and all other components are passive. I tried Eagle,
but couldn't find any simulation tool there. I tried Circuit
Maker and I couldn't understand how to do it. Are there

How do I do the noise simulation in LTSpice?
I get syntax error when I put in the spice op eg.
.noise vn001 v3 dec 20 50 500k
vn001 is the output node v3 is the input generator.

I am trying to simulate a simple led on/off astable on circuit-maker.
The diagram is here

My problem is that the simulation always seems to stop after 5 useconds

Where I can find LTspice models for UC3842 and UC3843 IC's?
Thank you very much.

I have downloaded the spice program from linear.com ;
I now want to simulated a circuit which contains an scr ;
It seems that there is an scr symbol, but when I try to
simulate the symbol is not recognized. Any ideas ?
