Heating food with electricity only

In this video, I’ll demonstrate how to reheat food in minutes by using electricity. To do so, we will only need a fork and an old electric wire. Let’s begin with some noodles! We will wrap the wires around the fork and spoon. Now, we will put both into the bowl in such a way, […]

Make your own Li-Ion Battery Pack

I recently got myself two spools with five meters of white LED strip that I want to utilize in a future portable lighting project, so once again It was time to choose a suitable battery type. Due to the superior gravimetric and volumetric energy density I wanted to either use Lithium Polymer or Lithium Ion. […]

What is electricity? – Electricity Explained – (1)

Electricity is vital to our civilization. So what is electricity and how does it work? To explain electricity we need to zoom passed the molecular and into the atomic level. Atoms are the smallest things we can kind of see, but not with the naked eye: Only with a scanning tunnelling microscope can we get […]

First, I’d like to make a celebration candle, which I’ll make out of a Jacob’s ladder; And second, …I’m gonna *give away four* of these Lulzbot mini to you, my viewers and patrons, […]

How to Make a Shunt Current Sense Resistor

Hi, I want to make a *beep* I said shunt! I want to make a *shunt* current sense resistor. Basically the way we measure current is by converting it into voltage passing it through a known resistor which we call a shunt and so the current is the measured voltage divided by the known resistance. […]

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? […]

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 […]
