I used two 74LS164s and conneced anodes of LEDs to the outputs, cathodes to GND (I know it is absolutely violating each design rule, but, hey, this IS a toy!) Take care, the built-in 120R resistors can abnormally heat-up and can make the die die! A 74164 might resist this torture a bit longer (200R resistors). Why don't you use current limitng resistors and connect the cathodes to output? By the way, can you make a wmv-file of the blinking? Kai |
