Halving Pulse Width/ Pulse Width Division

ng. So that is 30 cents a piece.

It was there, but is not there now. Must have been a mistake on the vendor s part. The cheapest I find now is $1.17 for one.

If your are using google groups, then go to the little triangle menu pull down and select "show original". Otherwise change the font of your email program to Courier.

I can't make head nor tail of it here either. Looks like this schematic's suffering from "Bloggs Disease." ;->

They just demonstrate that Bloggs doesn't understand the inner workings of a 555 and has generated a kluge. ...Jim Thompson

$5 isn't cheap enough for a Linux computer?

It's the earliest astable circuit the original designer had in mind and published. Of course you're going to disparage it after embarrassing yourself with that contraption you call a circuit.

Wow!

Thanks. I must have had the "free shipping" button on the second time I looked.

It's really not that bad. If you watch a video by Mike Engelhardt, the creator of LTspice, he shows you a lot of quick ways to draw the circuits. I am pretty used to it now and don't find it too clumsy.

If someone will hold my hand and show me how to make an instructive video, I'll demo original crispy flavor PSpice Schematics, which will out-run anything you can buy today, at any price. ...Jim Thompson

Really, LTSpice isn't so bad, really not bad at all.

Common components, R, L, C, GND, net labels, wires are just one keyboard hit away. Rotating and flipping components is just ctrl-r and ctrl-e, F7 and F8 allow reorienting or dragging components around, without or with the wires moving along. The mouse wheel zooms in and out, centred on the cursor location.

I particularly appreciate how one can draw wires through components and all the straight bits that short the pins of any single component together will magically vanish when you're done. A real time saver.

Can you detail one or two features that are missing or clumsy in LTSpice, and how they are dealt with in PSpice?

It's all about the user interface... so many to describe, but one example, to move in PSpice just click on the object to highlight it and drag it to where you want... in LTspice, you have to hit F7, then click and drag the object... those extra steps are annoying.

And the create your-own-part graphics editor in LTspice is on a level with MS Paint.

As a simulator, LTspice is fast... very fast... if you don't mind subtle errors like non-linearities linearized. I use Alternate Solver to avoid such issues.

If anyone happens to be visiting the Phoenix area and would like a demo, come on by... after I get my office organized... it's still a pile of boxes. The library is about complete, so the office is next.

Ah, right you are. Needs to be pulled up.
