There is something very magical about typing on those old-school manual typewriters. From the satisfying snap of the spring-loaded keys, to the gleam of the polished chrome accents, to the crisp marks on the printed page, typewriters make for a sublime writing experience. Now, the USB Typewriter lets you enjoy the magic of writing on a manual typewriter, without forfeiting the ability to use word-processing, email, web-browsing, or other modern desktop conveniences. Or, instead of using the typewriter as a computer keyboard, you can turn off your monitor altogether and type directly onto paper -- while discretely saving a soft-copy for later use!
In this instructable, I'll help you bring your old typewriter back to life by converting it into a USB compatible keyboard for your PC, Mac, or tablet computer. The hack is intended as a full keyboard replacement, so you can get rid of that piece of disposable plastic you call a keyboard and use the desk space for a classic, functional work of art -- A USB Typewriter!
Read on, and you will see that this modification is surprisingly easy to implement -- It shouldn't take longer than a weekend to do, and is within reach of any electronics novice. You might imagine that the project involves jumbles of wires and dozens of switches and sensors, but actually there are very few wires and absolutely no mechanical switches involved! However, because this project requires some custom components and circuit boards, you will need to purchase a USB Typewriter D.I.Y. Kit, which I have made available in my etsy store (usbtypewriter.etsy.com):

Signing UpStep 1: OVERVIEW
Under the hood of almost every manual typewriter is a spring-loaded crossbar that runs underneath all the keys (see picture below). Whenever a key is struck, part of that key pushes on the crossbar, and this causes the carriage to advance, the ink roll to move, and so on. We are going to repurpose this crossbar as a place to mount an array of metal contacts, which are attached to a long, narrow circuit board called the Sensor Board.
Take the time now to identify where the crossbar is on your typewriter -- just look for a bar that swings up and down when you press a key.

Thanks.
on the side of the device, so the buttons can be reached with the left hand while typing. You could of course mount your own buttons somewhere. Every typewriter is different -- that's why its a fun project!
but the mini pc is how much?

The "personal computer revolution" must be credited to both Altair, who "made the ball", so to speak, with their "8800", and IMSAI, who "got it rolling" with their "8080". As far as I know, both used the same INTEL "8080" processor, virtually the only "micro" in existence at the time. By adopting as "standard" many of the features of the Altair while improving significantly on their design, IMSAI helped create much of the market they both then, brielfy, supplied. (Altair's only real "advantage" was Bill Gates' BASIC, quite possibly one of the last pieces of software Bill can LEGITIMATELY claim to have WRITTEN HIMSELF...)
Of course the result will be less flexible but the USB connector is an expensive accessory.
Ebay/sparkfun doesn't seem to have bluetooth breakout boards with HID support wonder why =\
