Is this something more people than just you might need?
I like this project as its fairly straight forward and has a very clear application which makes sense to me. However if I would build one of these for you and charge you for it I would need to ask for more money than I am comfortable charging an individual with. (does that make sense?)
So - I would find this interesting if we could make say 100 or 1000 units and sell them at a profit. Maybe find interested people through Kickstarter once we have a working demo.
Do you think this is potentially possible?
Where are you located?
