Hey guys, got the clock home, made it and its fantastic
making up a housing for it for our airsoft game modes, only problem I have is its really quiet (well, not REALLY quiet but we need to have it audible over a firefight)
I bought a cheap £4 smoke detector, removed the radioactive detector part and now wondering what the best way of "piggy backing" on the pizo speaker would be? the detector is a Connect-it Smoke alarm http://www.mackay.co.uk/images/product/Jegs//connect-it-smoke-alarm.jpg
and it works with a A5364CA chip (data sheet: http://pdf1.alldatasheet.com/datasheet-pdf/view/55132/ALLEGRO/A5364CA.html
) and it also conveniently works on 9v too so I was going to connect it up to the boards supply provided I can get it to all work.
All in all I'm just trying to get the smoke detector board to peep at the same time the pizo speaker on the clock does, just so its more audible. any help on the matter would be appreciated
