Drawing schematics?

This is Mousey the Junkbot's schematic...does he even have a third wheel?

I would be very much obliged to anybody who can anybody draw this schematic out:

Worked out the circuit wiring for you two ways. The 3d wheel could be a swinging one or roller ball

When you say "I don't want to use this ic" - do you mean "I would be very much obliged to anybody who can anybody draw a different schematic that doesn't have an IC in it"?

LM386 schematic

Iceng gave a sufficient answer.

You awarded him a best answer, thanks - the system work better when people use that button.
But I think that while "sufficient" is adequate, you could have been more positive? - he's good.

I wanted to sound smart.

Good use of language, nowt wrong with that.
Next time you could sound smart and kind.

What do you mean?

To say something more positive than "sufficient" in future.

Such as...???

"Iceng gave the best answer!"

Iceng, you wrote a few comments I can't see...

what happened?
Reworded and deleted mistyping errors.
One small revision to your schematic, iceng. Break the connection between pins 2 and 3 of the IC. As drawn, both pins are always at the same potential and the IC will either never change state or oscillate wildly, neither of which was intended, I believe.

You can find a clear, large, original at Mousey's site.

Also, when substituting IC's, you must verify similar output capacity. Some of those you listed look like they as capable as the LM386. Some of the others look like they are a bit underpowered. I don't have personal experience with most of them, so i will defer to your experience with them.


To blinkyblinky - what is the aversion to using the LM386? It is cheap enough to go buy at the local "electronics" store (Radio Shack et al) that it precludes any reason not to use it.

Not enough milliwatt power...

This is exactly what I don't want to follow.

Has the OP altered the question??

Yes it has a 3rd wheel not powered so not shown on the diagram.

What's the OP?
