The Penna is a new Kickstarter project from a company called Elretron that looks to cash in on the current retro-tech craze by fusing the old-time aesthetics of a typewriter with the technology of a modern-day mechanical Bluetooth keyboard.
The Penna comes in two versions: the far nicer-looking (but presumably harder to type on) chrome-edged circular typewriter keycaps, as well as a more conventional square-shaped version. The mechanical switches offer a choice between Cherry MX Blue, Red, or Brown options, depending on the level of resistance and “clickiness” that you like from a keyboard. The keyboard itself comes in a choice of five colors.
The Penna connects over Bluetooth, and claims to be compatible with Windows, iOS, and Android devices. It runs off AA batteries instead of a rechargeable option, which is a bit annoying, and while Elretron notes that the keyboard lasts up to six months when idle, it isn’t giving any estimates for how much time you'll get in active use.
