There are tons of of keyboard fashions accessible on the market as of late. There are keyboards with mechanical and dome switches, there are fashions with and with out numpad, there are keyboards with card readers and trackpads. However there are not any trendy keyboards with a classic rotary cellphone dial that serves as a numpad. However apparently it’s potential to construct one your self.
The Rotary Keyboard undertaking by Squidgeefish (by way of MiniMachines.web) shouldn’t be precisely meant to allow new performance or enhance productiveness, however fairly than to make an Aprils Idiot prank. For a similar purpose, the keyboard lacks not solely its numpad, but additionally its numeric row as effectively to make the prank really work.
Arguably the largest problem with attaching a classic rotary cellphone dial to a contemporary gadget is that it’s analog and produces a pulse prepare as a substitute of a sign. Against this, trendy keyboards are digital, so there isn’t any technique to make the dial work with out putting in any further components. So Squidgeefish took a DFRobot Beetle Board based mostly on the ATmega32U4 chip which has 10 digital pins, 5 analog pins, 4 pwn pins and will be programmed to learn a pulse prepare with a easy program whereas nonetheless sustaining compatibility with an ordinary USB interface.

Bodily set up of a rotary dial seems to be fairly difficult too because it entails chopping a printed circuit board with out actually understanding which traces go the place. But, after a number of makes an attempt the modder managed to make issues work. To make the keyboard look kind of aesthetic, Squidgeefish needed to 3D print some components, together with the dial and the substitute for the numeric row which simply needed to go to make the dial worthy.
The top end result seems to be unusual, but it surely works: the dial can be utilized to enter numbers and symbols. It has nothing to do with steampunk keyboards with typewriter-style keys, however this was not the purpose of the undertaking anyway.
The entire price of the undertaking was in all probability decrease than $30, but it surely actually took a bunch of time to assemble it and make it work.
