ProTechTrader started with just one employee and kept it in the family for ten years. We are committed to supporting DIY, makers, and hobbyists of electronics. We are proud to provide components that can be tricky to find. Our premiere offering is the complete kits that we developed with Charles Platt for his book "Make: Electronics". Perhaps our biggest pride is our dedication to answering questions personally and directly with intent to teach.
