The USB Typewriter is the coolest keyboard that I have ever seen. These 'keyboards' are designed by Jack Zylkin, who turns an old typewriter into a fully functional keyboard.
Jack Zylkin custom builds USB Typewriters and sells them out of his Etsy shop. Prices range from $400-$500. If you are electronically-inclined, however, you can buy a kit to create your own USB Typewriter for $75-$150. Check out the video above to see the USB Typewriter in all of its retro glory.
