👐 Introducing Playwrite for @playdate

A dock and software combo that let you use the gorgeous screen of the Playdate for all your slow-tech typing needs, using a #teensy microcontroller and a bit of hackery.

The dock charges the Playdate – of course, and can also be used to play games with a keyboard or third party controller, so you can Executive Golf on your executive desk, using the input method that you're most comfortable with.
