For all those who swore off or even at the 555

I have a bunch, just haven't used them for anything for a long time. I do like the 555's wide power supply range.

The largest known prime number: 282589933-1

In my humble opinion, I'm always right.

Have not used one in 20+ years. Hope never to again.

In my case, why bother with a 555 and a bunch of other parts when I have a tiny somethingorother right here that will do the whole job itself with less bother, and less cost.

I probably still have one in the IC stash somewhere. In my youth I tried to build something that would beep when a code-locked door was kept open for too long. Never got it to work. Always been ignorant or plain stupid when it comes to that analogue witch-craft..

Had I needed that beeper today, any tiny would have done just fine and I would have a prototype running in less than an hour..

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

The 100ma current spikes on the power always seemed an abomination to me. The spec sheet won't tell you about them. CMOS is better but still has power supply spikes.

The last time I 'needed' one I used an ATtiny11 which was cheaper, didn't require all the external components and was more stable.

At my job 10 years ago
(cheap products with millions per year)
it has been said: If you can do it with a 555
nobody can do it cheaper. :lol:
