OTM-02 IS A 3D printed wristwatch

We like checking out roll-your-own wristwatch projects. getting a job little sufficient to bring around on your wrist is a genuine challenge. however we believe the OTM-02 wristwatch truly hit the type aspect ideal on the mark.

OTM means open source Time Machine. It’s the work of [Hairy Kiwi] as well as he handled to bring the digestive tracts of the enjoy in at a thickness between 6.5 as well as 7mm. That includes the LCD, PCB, piezo diaphragm, as well as the battery. The PCB itself is a four-layer board developed on 1mm thick substrate. It’s running an EFM32 (ARM) microcontroller which includes hardware USB support. The bit door sitting open on the side of the 3D printed enclosure supplies gain access to to the micro USB connector which can be utilized to fee the 150 mAh battery inside. That may not noise like much juice, however if you set the screen to show minutes only [Hairy] calculates a battery life approaching 175 days. If you just have to have the seconds displayed you can expect about two weeks between charges.

Like the name says, this job is open Source.
