To accomplish this task, he looked over the internal block schematics of a 555 timer and constructed a pair of high-power 555 timers himself, using discrete components to mimic those usually found ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

The 555 timer is a surprisingly versatile chip, and this project shows that there is some element of truth to the folks claiming that projects need naught but a few 555s.

An astable 555 multivibrator circuit, where the timing characteristics are determined by the interplay of an inductor, resistor, and diode.
