Dark Welder 2: My DIY battery tab spot welder

Dark Welder 2: My battery tab spot welder!After the failure of my $16 battery tab spot welder, I saw Kevin Dark’s DIY version.

But it wasn’t exactly what I needed, so I decided to build a modified version.

The Modified Dark Welder, or Dark Welder 2.0, has a foot switch that triggers a precise welding current pulse that is always the same length of time – no matter how long you hold down the button.

The best part is: IT WORKS!

While it may seem simple, it turns out that you need to do some investigation first.

In this video, I describe the different types of patch panels you may find in your home, how they work, and how you will use them (or not).

Why is my light switch popping and sparking?

Sparking Light SwitchOne day, you flip a light switch and notice a lovely popping sound. The pop might even be accompanied by a brief blue flash of light from within the switch.

Everyone has a home router, whether they know it or not.

For most of us, our router is the DSL / Cable / Fiber “box” given to us by our ISP.

You can, of course, add your own home router in between your home network and your ISP’s box. This provides an extra level of safety – among other things.

Those of us who are a bit more techie (and crazy) like to roll our own router. There are many reasons for this, not the least of which is security.

Unfortunately, not all routers are created equal, even when they’re “created” by you!
