I will happily use an entire arduino clone to produce a periodic pulse when it could be done with an NE555 timer. One will take me approximately 2 minutes, the other more than 2 hours.

When your build quantity == one, the concept of overkill becomes less meaningful.

I recall some Keysight "educational" video where the guy says, "This is my million-dollar cellphone charger" and plugs his cellphone into a USB port on a fancy oscilloscope.
