Ben and team might be onto something. While the logic gate board game had its issues, the "Hex" game is a lot more fun -- and part of the fun is learning to solder. Ben and Felix plan to turn the Hex game into a kit that could teach basic soldering skills as well as binary or hexadecimal arithmetic. Using Autodesk Eagle, Ben designs a printed circuit board and discusses whether a Lipo or AA batteries are a better choice for powering it. What would you do differently, or what do you think the team should keep the same? Let us know over on the element14 Community.
