Where can i find (scavenge) a 555 timer and other commonly used ICs?
A mini-question: what is the main application of the 555? I've seen it mostly controlling dc motors and
blinking lights and in some amps. Knowing the use of it is another way to know where to find it.
So, just like a stepper motor can be found in most (if not all) printers and scanners, where can we find ICs and other crucial parts for projects?
