Basic Tools Required
A few basic tools are required to build this kit.
1.
Soldering iron – adjustable temperature recommended, but not necessary. Your soldering iron must
have a sharp conical tip. I do not recommend a “flat-head, screwdriver-type” soldering iron. DO NOT
USE A SOLDERING GUN. They are usually rated at 100Watts and are overkill for this project.
