Here is the electonic schematic that i have develop and experiment on a lab-board.
This is to simulate the Stargate lighting sequence of the 9 chevrons, to be integrated in a full scrach of the gate.
A integrated circuit NE555 in astable mode at 1Hz frequency, rate of work 2 shift register 74HC164 to memory a logical "1" on these outs, for drive 9 Blue LED 3mm diameter; and fine, the register are "reset" by a NPN transistor for the sequence restart.

For the electronic epoxy card execution, you can follow http://www.abcelectronique.com/acquier/typon.html
http://www.selectronic.fr/article.asp?a ... .3304-9999
some sellers could do it for you ?
Or use a card with holes, to weld the components, and make the connections with wires between the components yourself

And here with a little modification, cause i was doing a electronic mistake who cause the 3 lasts blue Led not shinning in the good intensity.
