I've been tinkering with the Radio Shack Recording module to develop a repeating bird call. Something I learned from trial and error is you can remove the mic and land the wires on an output from a 1/8 mini plug and record direct from an MP3 player etc. You have to tweak the volume just right to reduce distortion.
Anyway, to trigger the 20 second bird call loop I spliced in a small NO spring loaded push button. It takes a quick button push on/off to start the 20 second recording.
Any ideas on how could I automate this button push every 20.5 seconds?
