That will just remember one wifi signal, delay it for 3 seconds and resend it while ignoring every signal that comes after it within that 3 second timespan. You'd be better off using a WATR delay line because it can hold more sparks than just one.
Let's agree that the signal record and replay must be user activated to make the challenge a little more difficult. (IOW the user must click/spark something to start the recording and click/spark again to replay it.)
