NewsBlur is pretty good and does exactly what it is intended for.

Wow, very impressed by the free Chapter 1. I like that it does not only look at integrated circuit, which have been covered many times already, but also looks at passives and discretes. The image quality and sample preparation looks to be t

This doesn't even cover all the neat assembly tricks with self-modifying code that you would actually use on a 6502 to speed up memory transfer.

The technology used by PragmatIC is not based on organic semiconductors though. The only organic material is the substrate (Kapton, I assume). The transistors are based on IGZO (Indium Gallium Zink Oxide), which is a relatively new material

It's one thing to build a few samples, it's another to mass produce with high yield. The GDR produced a 1 Mbit DRAM chip with great fanfare, but was never able to mass product it with commercially viable yield.

What unit is "Efficiency" in? Wh/km? It's interesting that VW seems to use a standardized 82kWh battery back in their MEB platform and achieves basically the same range as the Tesla 3 with 75kWh. Appears this is engineer

>The chip achieved a maximum operating speed of 71.4 kHz (at Vdd=3V/Vbias=6V) while consuming a maximum of 134.91 mW. Likewise, the chip can run as low as 10 kHz at 2V while consuming just 11.6 mW. That's really not that impres

Looks like it is not really a GPU ("Graphics Processing Unit"), but a video signal generator.

No, there is no series diode. There is an antiparallel diode to prevent solar cells from turning current into heat when they are shadowed.

I wonder how that compares to South Korea? They also managed to keep the number low for a long time. During Decomber 2021 there was a huge panic because suddenly there was a peak above 5000, but it subsided again. Now with Omikron it appear

I think it has never been easier to enter electronics (especially embedded stuff) than it is now. You can get a starter set including RPI/Arduino/Breakboard/Components for less than $100. Also, with a breadboard no soldering

I may be mistaken, but Teslas Dojo chip still seems to be relatively small. They can connect many of them into a 2D fabric, though. Cerebras still seems to have an advantage here, because they can use on-chip interconnects, which potentiall

It's a pretty clever process as some of the more critical steps (gate oxide, poly deposition) are done elsewhere. This allows for very stable transistors without a lot of Vth shift. I also like his use of resits for the ILD. Maybe it w
