Huge TFT Display with Arduino

Looking for new TFTs for my MSLA printer project, I found this 7" 800 by 480 pixel one. Using Bodmer's TFT_eSPI library I was able to control it.

How microchips are made?

This is a semiconductor microchip wafer and look how cool it looks, right? And the same wafer under a digital microscope and we can see all sorts of elements. Is made out of silicon and it contains millions and millions and millions of transistors. They are so small we can’t even see them under a laboratory microscope. You would need something such as an AFM microscope to do that, basically this is nanometer technology and in this video I want to go step by step how we go from rocks or basically sand, to silicon wafer, to microtechnology mask exposure and creating integrated circuits. Basically how semiconductor microchips are made. I also want to use my powerful laser engraver and maybe expose some chips and transistors and see inside them. I hope my laser is powerful enough to do that…  So, let’s get started.
