I’ve lost count of the similar mods I have done on various household items over the years. Often timer related like this one… but I would have used an attiny85 or similar MCU instead of the 555 because of the lower parts count and less analog parts to drift out of spec or dry out. I’ve found that just with a drawerfull of attiny chips I don’t have to keep a cabinet full of other stuff, and so far I’ve only noticed improvements in reliability despite the fact that I’m throwing 100,000+ times the complexity at the problem to be solved. For many jobs it’s 6-8 pins and you’re done, and a dead-bug SOIC in shrink wrap is tiny.
