Details

DoWatch, A DIY watch, software & hardware open sources

Overview

This is a totally hand-made watch, but wait... we won't made it for you. The only one that can bring it to life, is YOU!

Functionality

Default functions :

  • Displays Time, Calendar, and Temperature
  • Woken-up by shaking (configurable)
  • Custom reminder

More :

  • Step counter & Timer (coming soon in V2.0)
  • Customized functions

PS : all the functions can be modified based on the open source program, up to you.

Features

  • Case : actually, there's no case. It is formed by stacked PCBs. 
  • Gesture sensor : steel ball combined with PCB copper pads. ZERO power consumption if no gesture detected, not like any other sensor. 
  • Button : pressure-sensitive buttons, achieved by copper pads on two adjacent PCBs with very little clearance. 
  • Monitor : 1.3inch 128x64 OLED.  
  • RTC : high precision RTC chip RTC8025.
  • Temperature sensor : high accuracy sensor LM75.
  • Battery : wireless magnetic charger & rechargeable lithium battery, up to 15-30 days standby time after fully charged. 
  • Strap : standard 22mm strap horn, easy to change the strap. 
  • Packing : LUXURY.

Specifications

  • Idle power consumption : 4uA
  • Time display power : about 10mA
  • Full display power : about 30mA
  • Lithium battery capacity : 3.6V 40mA/h
  • Dimension with strap horn : 45 x 49 x 9mm
  • Dimension without strap horn : 45 x 39 x 9mm
  • Total length with strap : 241mm

Note :

  • For programming the DoWatch, you need a serial module : CP2102 USB UART Board (mini) OR CP2102 USB UART Board (type A)
  • This is a DIY kit, soldering tools and soldering experience for LQFP chips are required.     (If there's any problem, we are happy to solder the MCU and OLED for you, just leave us a message while placing an order)   
  • Double-sides tape, clamps, are also needed for installation but not included in the kit.
  • The default  program is still under developing, functions like timer/step-counter are unavailable for the moment, and maybe there are some BUGs (we'll fix them on the follow versions)
  • If any component is opened or soldered, which means the kit can not be sold anymore, therefore, refund or return won't be accepted, hoping for your understanding.

Weight: 0.249 kg
