Making an ARC Welder – Part 1 of 2

When I burned up the wires on my first Metal Melter, I decided to turn the transformer core into a stick welder. But one transformer wasn’t enough to actually make it weld anything. In this project we’ll be modifying 2 microwave transformers, because more transformers means more power. For this project I scavenged parts from […]

How to Make The Metal Melter

In a previous video I used a modified Microwave Oven Transformer as an electrical metal melter. In this video you’ll learn step by step how it was made, and what I’m using it for now. In a previous project, I found an old microwave in a dumpster and hacked it open to see what components […]

Why 3 Phase AC instead of Single Phase???

Hi. In my last video, I talked about how Tesla won the AC-DC battle against Edison. But then he shoved three-phase AC down our throats instead of single-phase AC. Edison: “Oh no, he didn’t. He always asked for too much” Ah, get lost Eddy! Obviously Tesla had a good reason. What is a three-phase AC? […]

The Scariac (Poor Mans Variable Power Controller)

Mixing water with electricity is typically discouraged, and for good reason, but in this project we’re pumping electricity into water, and a bit of drain cleaner to create a poor mans power controller. You might have heard of a Variac. This is the Scariac. In a couple of other projects, we fashioned a homemade stick […]

Make a Spot Welder for Cheap!!

A typical resistance spot welder like this can range in price from around $200 to over $800! That’s a little out of my price range, so for this project let’s make this one from common materials, and for just a few bucks! This modified transformer is the heart of the Spot Welder, and you might […]

Why Use AC Instead of DC at Home??

Hi. Why do we ever use AC to power homes instead of DC? Haven’t I showed you that AC is typically more dangerous than DC? [Painful Gurgle] Can we run everything on DC? Yes! In fact pretty much every device at home has to rectify AC into DC first before it can use it so […]

Making an ARC Welder – Part 2 of 2

In part 1 of this project, we scavenged some parts from household appliances, and modified them so we could weld metal. In this project, we’ll be rigging up the electrical system, and adding some finishing touches so that our homemade stick welder is ready for operation. I started this project with a scrap piece of […]

Homemade Stick Welder – From Microwave Parts!

I found this microwave in my neighbors garbage can. So I took it home, and turned into an AC stick welder. In this project, we’ll be testing out this contraption to see if it actually works. Because if it does, we’ll have the metal welding power to make a puzzle for entertaining guests, or build […]

Start a Fire With a Water Bottle

Normally, we’d think of using water to put out a fire, but in this video, you’ll learn how to use water water to start them. If you’re ever lost in a survival situation, here’s a little trick you’re gonna be so glad to know. To practice this technique we’ll use 3 sheets of paper, and […]
