Matterdaddy was a hardware company I started with a friend. The product was a game controller for the PC that enabled you to use it in your left hand while still using the mouse in your right hand thereby obviating the need to use a keyboard while playing stressful first person shooters.

I ripped apart several different controllers to build a working prototype to test with customers recruited off of Craigslist.

I worked with Plasticine/modeling clay to from ergonomics shapes based on measurements from my old human factors books from college.

We employed a third party industrial design and prototyping company to help us in forming a 3D printed model.

We then needed a windows app to configure the controller and share button/keyboard mappings through a cloud based service that we wrote.

We put the product on Kickstarter and managed to raise close to $45,000, but short of our goal.

In all it was a good experience, not a great experience... just a good one.
