With Karen's laser cutting design skills and Felix's soldering, the team has created a prototype of the logic board game using Karen's magnetic clasp design. Now it's time to give the concept a test run with help from The Game Craft proprietor JT Smith, whose experience with game design includes The Captain is Dead. JT says creating a game that's both educational and fun is one of the hardest concepts to pull off, and usually the design includes some compromises -- but where? While Karen contemplates JT's input, Ben and Felix hack an LCD display with the Pic32 Microcontroller and a DE0-Nano FPGA. Hopefully this will lead to a design that doesn't rely solely on LEDs! What do you think the team can compromise on? Or do you have experience driving an LCD screen with a microcontroller? Weigh in on build design over at the element14 Community.
