I did a couple of mods to Lavaguavas circuit it should hopefully do the job nicely :)

the 5 - 10VDC can be derived from the 13V AC that the existing bell uses

This is a first, one of my designs working (almost) first time :), thanks for the feedback Adam.

Good luck with the modifications Dave, thankyou for valuing my input.
