One thing I noticed with a scoop hookep up is that the resistor from the transistor's base to ground is realy needed and must be ~ 1k, 10k results in a too-slow switching off. If you want to use the internal osc you might need a lower value pull-up resistor than I recommend, maybe 1k too. > I agree to a point.
