iFixits teardown of Nintendos Alarmo revealed a magnet and Hall effect sensor in the alarm clocks control dial. | Image: iFixitNintendo is still shipping the Switch with Joy-Con hardware that will potentially develop issues like joystick drift and false inputs over time. Well have to wait until April 2nd to find out if Nintendo is fixing the issue with the new Switch 2, but as iFixit discovered during a teardown of the Alarmo alarm clock, the company is already embracing more reliable Hall effect sensors in at least one of its devices.Unlike disassembling most modern smartphones, iFixits teardown of Nintendos Alarmo appears to be relatively painless. Removing a single tri-point screw on the bottom of the alarm clock allows its faceplate to be simply twisted off, providing easy access to its internal hardware.There arent a lot of surprises inside Alarmo. Below its 2.4-inch LCD screen, youll find the 24GHz mmWave presence sensor the alarm clock uses to detect your body movements and whether youre sleeping through an alarm. Theres also an easy to replace CR2032 coin cell backup battery thats used to preserve settings while the clock isnt getting power from a USB cable.Somewhat unexpected, given Nintendos refusal to update its Joy-Con hardware, is the presence of a magnet and Hall effect sensor inside the rotary dial button atop Alarmo. That tech, which is already in use in many third-party controllers, should not only improve accuracy while using the dial to navigate the alarm clocks menus, but it will also help ensure that in five years time Alarmos dial can still work as reliably as it does today.
