We did this with our kid for years, including after-school programs as they got older.

During that time, my employer changed plan providers at least three times.

One made it easy, with a debit card that we would use for payment, others required we scan and submit receipts, and we would get reimbursed, either by direct deposit or a paper check.

There's no downside.

Because an individual photolithography machine costs millions of dollars to build.

The first prototype usually costs several times that.

To get smaller features, you have to keep using shorter and shorter wavelengths of light.

The latest machines use ultraviolet light. So, in order to see what's happening, you need UV cameras, and software to convert the images to something the human eye can perceive.

Then, you need to develop techniques that can etch those tiny features; it's roughly analogous to writing with a marker; what works when the letters are 4" tall doesn't work when they're 1/8".

You need ultra pure chemicals in an ultra clean environment. But many of those chemicals require special handling and materials to transport and apply them. Those materials in turn require exotic techniques to make and machine them.

So you might have to become the world expert in welding a particular metal, at incredibly small scale, without contaminating anything.

The world is full of failed attempts at all of these things.

You might spend hundreds of millions of dollars just to fail.

I think you might find a small table saw is more versatile. You will get straighter cuts than can be achieved with a circular saw, blade accessories will let you cut dados, and angle cuts for prettier joints.

Yes, you will still have to plug it in.

I have purchased all my books through bookshop.org since the scummy treatment of their employees by Amazon started surfacing. It usually takes a couple of extra days for a book to arrive, but that has made them more of a 'surprise' in the mail.

Also, if a book you want isn't available on Bookshop, it's usually because the publisher is in an anti-competitive agreement with Amazon, and you should call/email/tweet/toot the publisher (never the author) to complain.

Assuming your diagram is correct, your fixture is already wired incorrectly.

From the breaker panel, by convention, the black wire is Line, and the white wire is Neutral. The switch should be interrupting the Line, not the Neutral.

Code does not allow connections to hang in the air; they must be enclosed in a junction box.

The easiest way to have a neat arrangement is to use Wiremold products, which has boxes for junctions and switches, and flat conduit that can be run along the walls.
