How to DIY a Tennis Ball Launcher

(P.S. This is the Project Showcase from Makeblock Fan - slulu226)

One of the Makeblock projects got hot recently on Instructables about How to Make a Ball Launcher by slulu226. We contacted with this author, who is one of Makeblock big fans for over 2 years. This is the first time, she held a home workshop to build something awesome with friends last weekend. Here is the full part lists for her ball luancher. Most of them are from Makeblock official site
