In this video we will be having a look at a very versatile component, the TL431 IC. I used it in the feedback loop of my DIY switched mode power supply and thus got interested in it. That is why I will show you how it works, how you can use it in lot of different circuits and also how it functions in feedback loops of for example voltage converters. Let's get started!
0:00 TL431 is amazing! 1:25 Intro 2:28 Basics 3:19 TL431 as a Comparator 4:32 TL431 as a 2.5V Zener Diode 5:51 TL431 as an adjustable Zener Diode 6:30 Various other applications 7:20 SMPS Feedback Loop Theory 8:46 TL431 in DIY SMPS ... https://www.youtube.com/watch?v=isutYMU2HHU

In this video we will be having a closer look at AA NiMH batteries and find out whether they are obsolete nowadays. That means I will compare them to Li-Ion and LiPo batteries in order to find out all their advantages/disadvantages. Topics will include safety, price, size, weight, proper charging and discharging. Let's find out!

In this video I will try to create off-road tires as well as an overpowered battery pack for my electric longboard. For the tires I will be using TPU filament and 3D printing to create them and for the battery pack I will be using LiFePo4 100Ah cells. Let's find out whether both ideas will work out.

In this episode of DIY or Buy I will show you how I built a really sturdy DIY greenhouse over the course of 5 days. I had to build a new one because my old commercial one got destroyed during a storm. That is why I used the opportunity to create a DIY greenhouse by myself in order to find out whether it makes sense to DIY such a project or whether we should stick to the commercial solution instead. Let's get started!

I wanted to build an "Ambilight" clone for my TV ever since i bought the Raspberry Pi one year ago. After I finally managed to order the necessary special WS2801 LED strip a couple weeks ago, I started the build and everything went better than expected.
Join me for this awesome build.
