How to convert an air pump/vacuum into a two mode machine which can blow and suck? Answered
Hi, I'm trying to build a simple robot gripper under a budget using this idea http://makezine.com/projects/universal-robot-gripper/. So from what I understand I need a vacuum cleaner that can change into an air blower with a flip of switch using the same nozzle. Is there any cheap option where i can make something similar? I was thinking of buying a cheap car vacuum cleaner or a cheap air pump and reverse the mode by reversing the motor polarity. Will that work? Really need a quick answer for my project, please help. Thank you!
