Instructables user [Bruno] sent in his most recent creation, a robotic arm controlled using an old NES game pad. He scavenged the majority of his parts from a pair of old HP printers, including motors pulleys, belts and more. In fact, most of the metal and plastic components that he used come from the old printer chassis as well. He has included copies of the templates he used when manufacturing both the plastic and metal components, which should come in handy should anyone try to replicate his work.
[Bruno] also included all of the source code for the robotic arm and mentions that the project required two PICs due to pinout requirements. He ultimately decided to use two cheaper models over a single more expensive unit that would have supplied all of the pins he needed. His cost conscious build is impressive and undoubtedly demonstrates just how many old components can be reused in new projects if you really put some thought into it. Great job with this build, keep up the good work!
Be sure to keep reading to see some video of the arm in action.
