Gamification of the Dar Si Hmad Fog Water Harvesting Project in Morocco: Creating a role-playing course to integrate STEM and the Humanities

Our team created a role-playing curriculum based on the world’s largest fogwater harvesting project, pioneered by Dar Si Hmad, a Moroccan NGO. We created processes to gamify a course that integrates STEM and humanities content within the social, scientific and engineering context of the fog project. We developed characters, team activities and assignments to help students better understand social and cultural factors embedded in engineering problems. We also developed material for the NGO to use at the COP22 climate conference

Off-Grid Inverter with Regulated Output Voltage Amplitude

The paper discusses the design, simulation, and implementation of a 60W, 115VAC, 60Hz off-grid power inverter. The off-grid inverter creates a mains-level voltage from a 12V lead-acid battery input without connection to a conventional electric grid. The inverter includes a low-voltage H-Bridge circuit that is controlled with 3-level Pulse Width Modulation (PWM), and uses a low frequency step up transformer from 12V to 115V. A feedback system based on IQ sampling and a Proportional, Integral, Derivative controller (PID) is implemented to maintain a constant output voltage amplitude over an input range of 10 to 15VDC. A microcontroller is used to generate PWM and implement the feedback loop. The inverter successfully powers small household loads such as a desktop fan and laptop
