TDA_Fragile-box-circuit

I got this today (9/2/2009) from the TDA (Training and development agency) as you open it light on a sensor triggers a sample af Breaking Glass. The note inside says "By this time of year most resolutions are broken." its supossed to get me into teaching!!

 

The circuit of the TDA glass breaking sound parcel. There is only one resistor which controls the pitch and the LDR triggers the sound when light shines on it.
