Mk150

Hi!

I have some problem with this kit. At first it worked just fine, but not anymore.

The dice should be activated by the rolling ball switch (SW1), but it seems to be conducting at all times. Grounding pin 4 of IC1 will trigger a new dice roll.

Does this means that the switch is defect? Or is something else wrong?

/Per

Either the switch is defective or there is a problem around R8
Remove switch from circuit and check with multimeter.
