Abstract
The evolution in design philosophy for a portable test instrument for estimating the starch content of cassava roots is described. The instrument uses a radio frequency reflectometry technique to measure return loss using a coaxial probe. An on-board microprocessor then determines the starch content of the cassava sample based on a pre-stored calibration table. The design evolution started with a minimum viable hardware platform that was used for proof of concept and to gather preliminary field data. The next generation added wireless connectivity for cloud data collection and analysis, user interface improvements and rechargeable battery capability. Design focus then shifted to cost reduction, robustness and suitability for mass production so that the instrument can be put into the hands of farmers.
