Unwind from China? Can It Be Done?

 

This is a subject that has come up first in the comments with the @jameslileks post “Watching the CCP Press,” and which @iWe explored further by asking “whether one would trade with Nazi Germany.” We need additional information, indeed hard data, to even begin to look at the practicalities. Some here have mandated that we somehow absolutely cease trade with China. Others (and indeed most, I should think) would argue that an absolute embargo is both undesirable, and indeed impossible in any situation short of open warfare, but that we should certainly reevaluate what we are trading with China, and how we are doing so.

But to even have that discussion we need to know something of the extent of what we buy from China (and really, from everywhere else too), and how that really affects us, otherwise, should the absolutists be granted their immediate wish and all trade cease, the results may be distinctly unpleasant. I own and run a company that manufactures electronics, and so, at least as far as electronics go, I do have rather a lot of insight into what exactly comes out of China, and whether alternatives exist. I have done a Country of Origin query on the bills of materials (BOMs) for a couple of my products, and will detail those below, and what the implications are.

How to Build a Computer 5: Fundamental Chemistry

 

I know I promised simple transistor uses last time. Thinking about it though, I’d rather go into a bit more detail about the electron golfing I described earlier. It’s a neat analogy, but it doesn’t cover some things you can do with diodes. Interesting things. Therefore we’re gonna dive in for a deeper understanding of chemistry, atoms, and cartoons. Let’s look at a model of an atom using common household objects:

You all have your Ricochet mugs, right?

How to Build a Computer 4: Diodes and Transistors

 

We all love blasting things with ions, and most of us could spend all day shooting at wafers, but eventually someone is going to ask you to build something useful. What am I doing with all this mess of silicon anyhow? Here’s where we see the use of all that stuff. What do you suppose happens when you put a p-doped chunk of silicon next to an n-doped chunk of silicon?

One last cookie photo, then I’m going on a diet. Swearsies.
