For this smartwatch project I'm trying very hard to avoid adding too many features. I intend to do a few revisions of this project as I learn the skills needed to complete it. Recently I've acquired access to a proper solder reflow oven through a club at my university which allows me to construct boards using components that aren't hand solder-able, making a project such as this feasible. 

Alright, lets talk about features (and mind you this is revision 1 I'd like to add more later on) 

  1. Wifi/bluetooth connectivity 
  2. 3 button interface (couldn't source a touchscreen at this size) 
  3. 450mAh battery (USB rechargeable of course) 
  4. 1.44" TFT display 

More or less I want a micro controller on my wrist that tells time, and allows me to write my own extra code whenever I want. Naturally the biggest challenge here is going to be the PCB layout, everything needs to be thin so the board needs to have a cutout for the battery in order to keep a low profile. Overall I'm looking forward to this project.
