10 Led chasser

[mixos1]

This light chasser , i used to power 96 leds and used it as a lotto number picker , by tapping to each side of the electro. and runing the wires to a push button switch ,enabled me to create a short when the button is pushed, this stops the leds in there tracks . where the numbers for the lotto was below each led . this was tried with the other light chasser. but may still work the same with this.the other version had a 105 poly in place of the electro and allso had a logic ic instead of the timer. so ill post that one next time.

Steven,
Wow! You did a fine job doing that many-wires project.
If I ever need a pixel-screen built, I'll call you.
