I had a crazy idea but this just may work. I have been investigating RFID Chips. These are the little chips, literally the size of an asterisk, which are used by stores, by companies for asset management, shipment tracking etc. I want to glue one to my queen. This way I can locate her easily, determine if she is in the hive at all, and maybe narrow the search down to a particular frame. I am still studying it. I want to find (or build) a cheap scanner etc. The chips themselves are cheap enough (less than a dollar). The key is the scanner. I will let you all know if I can find a cost effective (cheap) way to do this.
There are these other devices called HOBO data collectors. They are also relatively cheap (about $30 or so), and small. They can sit in the hive and record things like temperature, humidity, CO2 levels etc. at any interval you want. It can measure these stats every 2 seconds or 2 hours which ever you set it to. The HOBO device then stores this data inside of itself. Every week or couple of weeks you take it out of the hive, hook it into your USB port on your PC and download the data. Now that would make an interesting graph. I am a bit of a tech head so I might get this to work.
My question is, is there any interest out there for this type of stuff? Please let me know. Maybe it's time to use 21st century tools to help us in our beekeeping. Totally noninvasive and benign.
