We appreciate your desire to help, but as has been said, its open source - the whole thread is there for you to look at. If you are not engineering minded, and your motivation is to make it cheaper for everyone, then you'll have to step up your engineering mind and figure out your own way to take what is already done and put it into production. As dcb said, Paul already
sells a pre-made kit so you don't have to assemble it, and I'm sure I'm not the only one here proud to spend every penny of what it costs for him to send out a pre-made kit. We all witnessed the conception and birth of the project and we're very proud of it and want to support him directly. Maybe its something you should PM him about and discuss it directly with him. I can see where you're coming from, and we don't mean to fervently tear your proposal up, but I hope you see where we are coming from too.
