Weight scale

In this chapter we build a 25kg / 55lbs rated weight scale to monitor the weight of a Hempy bucket. The scale is made out of two 35cm / 14inch round cutting boards with a full bridge load cell sandwiched between them. The cutting boards have several layers of lacquer for water proofing and anti-slip sticker on both sides to keep the bucket stable. The scale connects to the Hempy module with a 4 pin waterproof connector.
