March 13 2016 The following was developmental work, I now use the Hivetool sensor interface board I have been working on a hive scale base utilizing the Phidgets #1046 4 cell USB bridge (cost $90). The 24 bit USB bridge is supplied with numerous software drivers and a basic PC interface. We constructed a rigid aluminum frame using 1.25" X .75" solid aluminum bar stock. The scale frame perimeter matches the Langstroth hive body and sits under a standard wooden hive base. Four 1/4" thick load compression pads (not shown) at each corner are used to equalize the load across the four Zemic L6D 30 kG load cells (Ebay $19.99). Maximum hive weight 265 pounds.
