Happy 50th Birthday to the Signetics 555 Timer IC

Signetics announced the NE555 timer/oscillator IC in 1972, 50 years ago. Over five decades, this simple 8-pin chip has consistently sold in the billions, each year. It’s a perennial hobbyist favorite. Well-known authors such as Walter Jung wrote 555 timer cookbooks, and 555 circuits have been popular for new circuit designs since the 1970s. Engineering acceptance has been mixed. Some engineers routinely put 555 chips in their circuits. Others … Read More → "Happy 50th Birthday to the Signetics 555 Timer IC"

" actuation actuated " feedback ( which clicky-feel does inherently ) saves me from personal aggravation at being forced to wait on the dumb bucket of bolts, presumably to appreciate agape the digital wonder of it all even from the list of feedback second-bests ( display, beep ), the control is tolerable if not too awkward

Good article. Brings back a flood of memories of when I was a "digital" chip designer at Cal-Tex Semiconductor (purchased by Fairchild) during those times.

I do not know why this level of technology poses as consumer gear, except that it's built down to a price. User interfaces in the form of buttons and displays cost money.
