LED Help

[Rick1805]

Ok I am building a case and have the theme of stargate
I am looking for a led set up that would turn on leds from 1 to 7
then flash then start over anyone have any ideas???
here is a sample of my window

You may be able to modify this to do what you want.

Id say thats ideal mojo.

maybe you could get that inner "ring" to spin too?

It would be relatively simple to modify the circuit that Mojo's highlighted, if you have some knowledge of electronics. The chaser circuit without modifications will give you ten outputs that will 'chase' in one direction. With a bit of work with some extra diodes, you can make the behavour look a bit more interesting.

Doctronics have a page that features the chip at the heart of the chaser circuit, so you can get a feel of what might be capable.

The 'ultimate' version would be one based around a programmable microcontroller, but this requires you to have a good familiarity with both electronics and programming.

What level of understanding do you have of electronics?

[Rick1805]

I have a good understanding of electronics figuring either
one would do what I need it to do I can modify either board to do what I need thinking I might buy the chaser one and mess around to see what i can come up with
and yea it would be cool to get the inner ring to look like it spinning was thinking of a rulet (sp) wheel type game would work for that

With the chaser one, you can diode OR lines together to drive LEDs in the pattern you require. Think of the decade counter outputs as an input to a matrix of diodes which shunt signals to where you want them to be.
