Build a Hand-Held Microcontroller-Based Scoring Device

A design-for-manufacturing approach was taken for
the construction of the aluminum-chassis prototype. The main
two-sided PCB has ample room for parts, mainly because of
the housing size needed to fit the AAA battery pack and LCD

The QuizWiz is an innovative hand-held device that teachers can use to score multiple choice tests. It’s unlikely that you’ll need such a device, but you’ll surely learn a lot from Paul Kiedrowski’s description of the design process. He covers … Continue reading
