Hi there

If your main focus is on randomizing stuff then you can use any ADC pin, instead of a RTC, for the same task. What I mean is read values from any ADC pin and then process it to give you the seed for rand( ). You need not to connect that ADC pin with anything alse, not even GND; well this will be the reason why you would get randon analog values. Try it out.
