I need a 10 SECOND pulse stretcher!

I vaguely recall doing that using a counter, but can't recall the
details.

In spite of my analog background I like the precision and stability of
digital, but I've fallen back to complete simplicity, a single 555
Timer... that ought to make Slowman and Jerkin happy ;-)

(I found some high quality 2.2uF film capacitors in my junk :-)

Excellent choice, and having the *******s grit their teeth makes it
even better!

555, hilarious! Sounds like digital scared him off again.

To me it sounds like: "smaller, faster, better, cheaper." won.


Yep. Digital was elegant, but required a clock (555 :-) and a counter
chip and some gating. As a pure stretcher, all you need is the 555.
The only thing pushing me to digital was that I didn't know I had some
high value, high quality capacitors on-hand. Once I discovered those
it was no contest.


I noticed no solutions of any kind from you, bigmouth, so I don't
think you have room to talk.

Jerkin's "suggestions" would be laughable (as usual), thus his
reticence :-)
