A USB Typewriter?

This may be an elaborate hoax, but it sure looks real.  The tagline looks like a joke, though:

The USBTypewriter™ is a new and groundbreaking innovation in the field of obsolescence.

The claim is that this fellow has developed a circuit board that can be attached to any old-fashioned mechanical typewriter, converting it to a USB keyboard input device.  From a technical perspective, this is completely plausible.  From just about any other perspective, it's some degree of crazy (and leaning toward very crazy).  Here's the company page, the Etsy storefront, and below is their marketing video.




I'm pretty much speechless...
