Why? Is there something special about using 555's that I don't know about? A 2 bit full adder is a really simple circuit...

- pavel_lishin 16y agoI think the specialness comes from the fact that they're just timers.
- sagacity 16y agoYes. What you're saying is probably because you don't (yet) know what uses can a (simple circuit built around a) 555 be put to. Back in 1985/6, I built a (simple, ham) radio transceiver mainly utilising 555s, 741s (and some crystal oscillators + other discrete components) with which, I actually communicated with people from more than 50 countries around the world, without spending the cost of international phone calls (which was prohibitive then). Edit: And long before I did that, other hackers used to do similar - or even better - things. :)
