Trying out a hardware side project this time. Figuring out a way to track your surf board or kite board once it's lost at sea during a session. It's a pretty interesting challenge.
I've got a number of things I would like to work on that are more into the realm of hardware. One thing I'm really wanting to work on is a way for me to manage and interact with my cars ECU through a web interface. Would be useful for a number of things, such as keeping a better maintenance schedule, useful statistics, maybe even tuning...Seems pretty fun.
As far as tracking goes, I can't think of a need for it with my idea, but I know it's used a lot commercially already.
