Toward a DIY smartwatch

The original inspiration for this is Tinkernut's project. (Gerd Lobmeyer, Open Green Energy and others have done similar projects.)

Considerations

  • Power
  • Size

Components

Display

Old school LCD

I'm thinking of pulls from old mobile phones, esp. Nokia. Power use should be minimal. Availability (used) should be good.

New school LCD

What's available? Again power consumption should be small when backlight isn't used. Looks like finding something suitably sized with workable I/O connections is going to be difficult.

OLED

What's the power consumption?

Controller

w/ integrated BLE

w/o BLE

Other

  • Use a Nordic BLE module for everything?

Bluetooth

Classic

  • HC-06: $TODO, TODO mA, size is a bit big.
  • HC-05: $TODO, TODO mA, size is a bit big.

BLE

Battery
