I wanted to show the circuitry that I used for the Boba Fett and Custom Chest displays. I hand drew them so pardon my chicken scratch. All integrated circuits (IC) have labeled pins 1-whatever. If it has 8 pins then it is 1 through 8. The way to tell which one is 1 there is a small dot placed in the upper left of the chip closest to the 1. If there is no dot then the notch side is always up and top left is always labeled as 1.
This is the 4017IC
The outputs are labeled as 0-9 and those are the outputs that go to the top led sequence for the Boba Fett display using 0-4 or my custom displays using 0-9, or 0-8.
This is the 555 timer that drives the 4017 Decade counter.
R1, R2 and C1 determine the pace of the timing of the circuit. For reference the equation is 1 Meg Ohms times 1 Micro Farad equals 1 second interval of OFF time. The R1 resistor determines the ON time at about the same rate. So connected like this you get the Boba Fett display.
If there is anything you need to know about this circuit or wiring please let me know.
