Build This Giant Chip

Follow along as we build and test one of our favorite kits of all time, the Discrete 555 Timer! Build a huge version of one of the most iconic and surprisingly versatile integrated circuits of all time from transistor and resistors.

The 555 chip has been used at one time or another by nearly every E.E. alive, and you can use it to detect pulses, make lights blink, debounce inputs, trigger alarms, and even make music (terrible music, but music nonetheless!). We first wrote up the kit in our Hands On column in Spectrum (link below), and this is second version, which features some improvements over the original.
