6 commentsI wear mine every day. I've been helping out with the firmware's maintenance too. We recently merged dozens of pull requests. People actually wrote games for this watch, it's insane. The movement software is undergoing a major refactoring in preparation for the new board's release so it should be even better in the future.
Really looking forward to getting the new Pro board and the custom LCD which has more features than the Casio LCD as well as none of the limitations. It's showing hints of becoming a fully custom watch. People have designed and manufactured custom titanium cases. Who knows what the future holds.
I would love an SPL meter on my watch with weighting filters! Don't know much about piezo buzzers but I wonder if it could be used as a microphone for this purpose.
