Building this very special Anti-monster flash light & buzzer is a nice way to experiment an electrical circuit a bit more complex than the usual battery/bulb/switch one.

 

Avertissement Beware that once completed, this is a very noisy device...

 

This DIYs project uses a very energy efficient LED (light emitting diode) that has also a very long lifetime. Household light bulbs using this technology are now on the market and might replace one day fluorescent light bulbs.
