10 Led chasser

Recommended Posts

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.
