Best Electronic Soldering Badge Kits For Classrooms
Learning how to solder is a right of passage for any maker. Personally, I remember holding out for the longest time, relying on alligator clips and breadboard jumpers to complete beginner projects and simple circuits. Soldering is intimidating, and the prospect of mangling a project while you learn the basics technique can compound the anxiety.
The best way I’ve found to dip your toe in to learning to solder is with a fun, inexpensive soldering badge kit. These come in dozens of varieties, with a wide range of cost, which I’ve outlined here.
Boil them down, they’re essentially a simple LED circuit, powered by a coin cell battery. For both students and instructors, they offer a quick project with a high payoff. Plus, you literally get to wear your new skill as a badge of accomplishment. How cool is that?

Hakko FX-901 Cordless Soldering Iron Review
This is the Hakko FX-901 portable soldering iron (available on Amazon: http://amzn.to/2sh7g0t). It runs off 4 AA batteries that you can swap out really fast with this removable cartridge design. I use rechargeables in mine and I get over an hour of use out of it before I notice the temperature drops. Alkaline batteries will run hotter, but not last as long.
