why is that exactly?

@@ahmetyusufsalim Because he has little hesitation and smooth, consistent data flow, complete with model demonstration and explanation.

Old school presentation. Ironic given the subject.

I would think that he gives this speech a lot.

Nerds are fluent in nerd speak

^ Exactly what I was going to write. :-)

It could be done quite effectively in a 3D program as well; namely VR for the easier interactivity of it.

@@MsHojat Thats actually a good idea, such a simulation could also have visual elements to highlight stuff too, and I don't mean just components being highlighted from context in description, but also stuff like where there is current and how it travels when the user tries sending stuff into the inputs.

Normal youtube comment would be "you dont want aids in college nerd... hehehe..." but I was thinking the same thing... i´ll see myselfe out.

Absolutely.

The 555 probably has too many components to get a quick and simple grasp of basic chip construction. It's a very useful chip though.

@@maximosh Actually no, it's surprisingly simple. there's maker kits you can get of it that are jumbo IC (shaped) PCBs with nothing but discrete components. ukposts.info/have/v-deo/m5Gap4F5g5uk1Hk.html

@@RonLaws it is not at the same magnify factor of the acrylic model of not gates. There are too many components

I grew up behind the Iron Curtain and studied electronics. I'm not sure whether it is due to the place I grew up or whether my teacher was exceptionally good, but this is almost exactly how I learned how chips are made.

Yes!

plexi+glue gun + saw +time = profit

Thanks! I was wondering why there seem to be resistors sitting there not connected to anything. Thank you so much for the explanation. It makes such great sense that you could make, I wouldn’t call it a universal chip, but you could certainly make a chip that could be turned into a couple of different final chips based upon the metal layer.

I am extremely curious as well. All it looks like it was doing was blinking at alternating intervals.

You will need SEM for that. Plus, you it wouldn't be easy to see actual transistors of the ARM cause it's covered by a lot of circuitry removal of which would be kinda tricky.

It seems that they have etched away the top portion of the microcontroller to show what the insides look like.

@@0lleman Good spot!

This is pretty common saying in my university in europe and it was so funny to hear him say it in english lol

You should learn more words. Some are quite useful - But I agree, it's exceptionally educational.

It's a possibility. But to me it looks like they tried to cram in a third gate but gave up on it and never bothered to manufacture a cleaned up stencil.

Sometimes features are built into chips simply for testing to make sure the process is in control, a "quality control only" feature. I am uncertain that this is the case with this chip.

I also want to know what the unused components are for. Are they artifacts from the development process? Are they there for structural integrity? other? I would also have liked a better explanation on what the transistors in the chip was made of. Like the "gap", the word implies its air or vacuum, but the model had something solid there which implies the real one does too, and I am unsure how the base would be held in place away from touching the collector if the gap wasnt solid and the base has air on all sides.

@@feha92 look up pnp and npn transistors on UKposts. It's basically 2 different types of silicon duping, so the different layers of materials are basically just n silicon and p silicon.

@@feha92 One possibility is that the same silicon was used to make chips with different functionality. If you have enough transistors, etc., in the silicon, you can implement different functions just by changing the metal layer(s) that wire(s) things up. Making new masks only for one or two metal layers is much cheaper than creating a complete stack of masks for new silicon. (This is even more true today now that many, many layers of masks are needed and the bottom (finer) masks are much more costly to make than the top ones for the metal layers. Today's complicated silicon devices typically contain lots of extra transistors, gates so that if you are lucky, bugs can be fixed by only changing metal wiring.)
