Makes a great repeating plink sound!
Create a pleasant alarm signal
It's somewhere between a dripping faucet and the electronic chime dinger in a new car! The EDF1 makes a pleasant but very attention getting repeating sound! Plink plink plink plink just like the water faucet dripping into a bowl of water! Use it for anything that requires a different audio alarm signal or simply to drive your friends nuts! Plus you will learn how a simple transistor oscillator together with the eternal 555 timer IC can make such a sound!
