My bro (Steeeven1 here on YouTube) was able to get hold of 2 fire bells, and he connected them to his usual combination of 'motor speed controller' and 'microcontroller'.

The program is extremely simple and is just to test the circuits, really. A few minutes ago (before uploading this video) I programmed an on-the-hour chime, where they pulse the appropriate number of times (according to the hour) when the hour changes. Maybe I'll upload a vid of this soon, but it's not particularly much more interesting. :P
