Introduction: Cheap Soldering Iron Upgrade

Picture of Cheap Soldering Iron Upgrade

I Bought this cheap soldering iron for ten dollars. Because i like make things and upgrade them, I decide to upgrade thist stuff a little bit. The reason to upgrade was, that i several times leave it alone plugged by mistake. It can be dangerous regarding fire, so i needed indicating light. The simplest way for me was use switch with pilot light. Problem is that the electric cord leads to soldering iron, so the switch would have be on cord, but it´s weird :D

So i decided for this:

Step 1: Material & Tools

Step 2: Prepare Snatd

Nice. I put an inline rotary cheapo switch on my iron which already had lights on it and also plug it through a 3 speed fan control so I have a medium heat range as it got so darned hot it wouldn't tin. It just boiled off. Good job though.
