Or program a PIC microcontroller with a button for each 10 minute
increment and a simple DAC to create a soft chordy gong noise in
software. Bit harder than a CD though.

The person who posted the "5 silent tracks and a chime" idea should
consider that this is exactly the sort of thing that would sell to
hippies on ebay.

Ahem !
The idea for 'x mins silence + a sound' actually came from the
Spiritualist Church I used to work for in Ipswich.


Not the bethesda baptist church ?
