•open the switch next to the battery to begin• Made this one months ago but never posted it. I pulled it of the shelf because I see how I can use it as an example. This is a astable multivibrator- that's right, it's got the same topology as that infamous little blinkie. More or less, that is. The components are all connected the same but I've added another transistor and the resistors and caps that go along with it.
I want to show that your blinkie doesn't have to be limited to the boring old "back and forth", or be made to march endlessly down a blinking straight line. You can make your blinkie do all sorts of fun stuff!
In this example I used three segments, each one driving four parallel LED's. Each segment got it's own color, and I arranged all the LED's into four groups. Each group has one LED from each segment, and they're all positioned to do a fun, spinning around motion.
You see?- with a little imagination you can turn a worn out "please just put me into a trash compactor" blinkie, into a shiny new "hey everybody check me out i'm the amazing fantastiblink!" blinkie..
