Hi All,
I'm an ecology graduate student trying to do a bit of electrical engineering and having zero success. The goal: broadcast bird songs for about 6 hours each morning for an experiment I'm doing, preferably somewhat autonomously so I can have sufficient replication.
I have a mini boombox connected to a 12V marine battery with an on/off timer in between. The problem is, when the timer interrupts power and then returns it to the boombox, I have to press the play button to start the track playing again (and if I leave the button taped down, it pauses play on the boombox). So my first question is: does anyone have an idea of how to design something that can make noise for 6 hours, then stop, then start again the next day better than this design? Alternatively, are there any "fixes" that would get around the fact that I need to press the play button every time power is returned to the system?
I realize this question might be a bit more involved than is appropriate for this forum, but I'm just looking for some ideas. Thanks.
