I have been thinking of creating an instrument to measure bee activity using a microphone and a data logger. The standalone data logger is only 16 bucks and plugs into a USB port. The microphone is cheap and I don’t yet know what I need to make the microphone talk to the data logger, but I am thinking I would convert the SPL (sound pressure level) to a voltage and trigger a time stamped data point whenever the SPL reaches a threshold. More data points = more bees. <o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>We could make these things for fifty bucks, ja? One way or another, we need some kind of standard instrument to measure bee activity. I think I am with Dave and BillK: we are seeing a combination of cumulative toxicity, parasites and starvation working together against our beloved partners in food production.<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>spike<o:p></o:p></span></p></div></div></body></html>
