"I can't find any potential customers." Is a dandy excuse.

It's not sympathy, it's sarcasm, and if its "comforatable" enough for
you to not need to look for work then, in reality, you probably don't
want to work.

Since your unfamiliarity with the device itself from a hands-on point of
view suggests that you only learned about the problem from Kamenzind's
book, I suggest you're the one suffering from a lack of circuit design
experience since the rest of us generally solved the problem by
connecting an adequate reservoir capacitor across the chip's supply
terminals.

With the advent of CMOS 555s, however, (Maxim's ICM7555 for instance)
the problem has been eliminated.

You don't seem to see it.

And yet I see no self-referential satire in anything you write.
