When the Ninth output goes high the 10th LED is lit. When the first completes the count, on the next clock pulse the first sends a “Carry Out” signal which acts like a clock input to the second. The second moves from output 0 to 1, turning off the first transistor and turning on the second.

This “Carry Out” command can be used as a clock input for the second. No need for any gates.

Every time the first carry’s out, the second one clocks to the next position. Each transistor is tied to the negative lead of 10 LED’s each. The 74 series does not have a carry out. There is probably a way to use the last output from the first counter to act like a carry out.

But you’d be limited to 9 outputs on the first, and up to 10 transistors to complete up to a 90 LED string of a chase light. You would probably also have to use the master reset with output 9. I’ll have to investigate that further. My parts arrive tomorrow. The next question is what to do with the 10 74HC’s I have arriving tomorrow. I certainly have enough ‘s.

Plus, what I really like about the push button idea is that the kids can send any chain of lights up that they want. But now I have to order SR’s. Can I send the last shift register back to the first?

If so, and the kids hold the button down a long time there could be an endless stream of lit lights. That’s bringing up a problem: If all the lights are lit at once, my power supply won’t ddatasheet strong enough to power that many devices.

One to send highs 1’s and one to set low’s 2’s.

Sounds like good advice. I can send the single pulse to start one soldier marching up the chain. When it gets to the end he dies. But the is sending more soldiers. Meanwhile, the kids can keep sending more and more soldiers off to war, each dying at the end of the string.

I think I’m beginning to settle down on a plan. The choice now is whether to go with the 74HC’s or to order some SR’s. For your question about power, use high cd4017hcn LEDs and 1mA is plenty if you have a whole mess of them. A little 1 amp 3.

Aug datashete, 4, Seems a comet tail was mentioned so here is a simple tested version for either or SR like 74HC The LED used were a disappointment as viewing angle is about 30 deg.
