OK....Here goes....I was briefly in contact with Wayne Esaias of NASA as they have a global hive weight scale project. They map them from space and recored weight gains and losses during the whole year for study. I had seen pictures of the scales beekeepers are using to weigh their hives and they are usually the old Fairbanks baggage or cargo scales. He mentioned to me that one can build a high tech scale using load cells. I had never heard of these so naturally I "googled" them and lo and behold. One can construct a scale using these nifty devices. I am trying to figure out exactly how to do this so if anyone out here has any ideas I would appreciate a collaboration of sorts. Wayne also mentioned to me about "HOBO" data collectors. These are quite nice devices which are placed inside the hive (they are small) and can record temp, relative humidity, CO2 etc every few seconds or minutes. Every couple weeks you trot out to your hive with your laptop, plug in the USB cable and download the data. These 2 devices would make us all high tech beekeepers. I just need some help in figuring out how to make these work and hopefully we can share our info. Any takers????....Please let me know.
