The Clapper! – Science Fair Project progress

by on Apr.04, 2010, under science fair

So, after putting it all together and trying it with success several times, we realized it was time for the ultimate test — triggering it with Robbie’s actual alarm clock. Off Robbie ran to get the clock, and a few minutes later we had an alarm going off.

But not the circuit.


Talking loudly worked. Clapping worked, very well in fact. But the alarm did not. Even when held quite close to the condenser mic.

We have not created an wake-up alarm light trigger, but instead have created “The Clapper” Everybody join me for a chorus of “Clap on! *clap* *clap* Clap off! *clap* *clap* Clap on! Clap off! The Clapper!”.

Hmm, what to do about this though. Robbie decided he could simply talk about the invention at the fair and show them that it triggered by voice, and hope that is good enough. But it is a disappointment to not have it fully function as we wanted.
