NOTE: These instructions are for my original "Solder-It-Yourself" conversion kit. However, I have since come up with a much simpler, no-soldering-required version of the USB Typewriter Conversion Kit, and -- take my word for it -- it is is much easier to install. If you want to learn about how to convert your typewriter the hard way, read on! Otherwise, check out the No-Soldering Instructable to learn more about the newer version of the kit.
Step 1: Introduction:
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):
