Got some empty plastic bottles in your recycling bin or cluttering up your desk?

He shows the machine in operation and then spends several real-time minutes showing how he made the heart of it using plastic bottles, the conductive brush from a laser printer, discarded CDs, and a bunch of copper wire. As a bonus, he removes the conductive material and paint from a CD with a homemade taser. As a super special bonus, there’s no EDM soundtrack to this video, just the sounds of productivity.
