How can I make an object emit a single particle with predefined frequency I have no actual blend file for this, as I have not managed to make it work, but in essence I would like something along the lines of a tap that drips water every 1/2 sec or so. Is this at all possible? Any tutorials I have found simply emit a no. Of particles at random with no set frequency.
If the frame rate of the output is 25, and the particle system duration is 200, we need 16 particles to have one every half second.

You can for instance use a mesh with a single vertex (if you want the drip to be at an exact position):
