A NE555 could be sufficient and even more reductionist. =;-) Circuit example <a href="https://theorycircuit.com/ic-555-ic-741/adjustable-duty-cycle-pwm-generator-circuit/" rel="nofollow">https://theorycircuit.com/ic-555-ic-741/adjustable-duty-cycl...</a>
This does the typical "two short buzzes with a break in between". I think that would be hard with a singe NE555, and of course much more annoying/complicated to fine-tune.<p>Also, the random delay between the notifications.
A CD40106 could do the same and would even be more reductionist (and uses less current).
That’s brilliant. A phone’nt, if you will.
Really needs an update, the No-Tiff-ier, that also doesn't display an image, in addition to the other features.<p>For 2026, the No-Tiff-AIer extension is planned to also not bury you in slop.
