From Instructables user hydronics comes this electronic bee-counter that mounts over a hive’s entrance, dividing it into many channels, each as wide as a single bee, and each equipped with a pair of IR reflectance sensors. When a bee passes through, the order in which the sensors are tripped reveals if it is coming or going. The sensor array is mounted on a custom PCB designed and printed through a local hackerspace, and mounts a Teensy++ for control and USB communication with a laptop, wbere a Processing script uploads the data in real time to Google Drive. Code, circuits, and parts lists at the link, below, or check out the whole project at World Maker Faire this weekend!
