This blog will keep to a simple theme of my tinkering with electronic and computer related toys, gadgets, projects and the like. I do hope from time to time there is something for someone to find when they are exploring these things for themselves. From an early age, I was always attracted to electronic gadgets an I continue to enjoy myself with my hobby. Unfortunately with a busy life, time becomes short an I can not indulge myself like in the past.

The SM-200K kit is to help one get familiar with working with Surface Mount Technology. The SM-200K Decision Maker will answer any question the user asks. When the asked button is pressed, six LEDs are driven on and off; in addition, a buzzer will sound. After a few seconds one LED will remain lite answering ones question. Over a few minutes this LED will dim and then go out. The Theory of operation of the SM-200K is six LEDs are driven by a decimal counter and two oscillators. The decimal counter is driven by one oscillator and the buzzer is driven by the other oscillator.
