Help with bussard led schematic

Would anyone happen to have a schematic for an led rotating bussard for TOS Enterprise or NX-01...with a trimmer pot to adjust rotating speed. I've made a search.....unless I missed it. Thanks for any assistance.

in the sticky portion is the Johnson counter, that's the meat of the circuit.

I'm afraid you lost me sparky. My electro-know how is somewhat limited.

I'm making adjustments to a working circuit kit I got going now...I have to build and test on it some more. But the circuit so far in the domes works OK and ajustable. The pair of discs in front the ones with all red LEDs of this picture is the prototype disc boards for the 1/350 NX-01.

Fifteen (15) 3mm Red LEDs with a 3 step chaser circuit gives the illusion of 5 red rotaing lights in the NX domes.

The main board will also do the Red and Green position lights and I will add a LED strobe like blinker circuit for flashing White (4) LEDs

Hello Don,
When do you think the NX-01 lights would be ready?
Thanks

Not sure how soon but I have the circuits laid out, parts handy...I just got to build it. Looks to be a busy week if all goes well on other projects already commited to.
