The maximum Build

While thinking about this little project there might happend some featurecreep. But i will put all the Ideas for this little Gadget into the wild, so other will maybe give tipps for even more features.

Hardware
- Output
  - Display
    - LCD or OLED
    - eInk (maybe as backpack for showing pager information)
  - LED
  - Vibration Motor
    - page like functionality
- Input
  - Blackberry Q10 Keyboard
    - maybe a stm8 based keyboard controller to not use up all the main MCU pins
  - NFC Tag Reader/Write
  - Buttons
  - Rotary Encoder
- Other
  - Realtime Clock
- Main CPU/MCU
  - ESP8266
    - not enough pins?
  - ESP32
    - could be main MCU or also just wifi coprocessor
  - STM32
    - no build in WiFi
    - could try to code in rust-lang
Batteries
- would love to have 2 to 3 days of usage
- Charger via (micro)USB(-C)
- 18650 (Between 1 and 3)
Storage
- SD/microSD
- create eeprom cartridges?
  - need to find a small/cheap pcb edge connector for this

So, what about software? I'm actually writing a worklog right now about the software side of "personal information managers", so I wish this project expanded on this, too =)

Are you sure? yes | no

since i want to have wifi, i would love to have owncloud sync for notes and calendar.

AND i need to find out how to get random bin files loaded as executables so i can load apps from a sd card

Are you sure? yes | no

ouh, tell me when you find stuff about the last one, I need that (although for the ESP8266)

Are you sure? yes | no

I'm missing one important item in this list: size and weight. It's good idea to consider this at the beginning, as it may interfere with some other items. Also, it may help to cool down the feature creep.

Are you sure? yes | no

so there is the keyboard + the (most probbably 3.2 inch) display and the 1-3 batteries determing size and wheight

maximum size would be PocketCHIP size

Are you sure? yes | no

Q10 Keyboard Adapter (My first hot air experience)

Blackberry Q10 Keyboard (destructive) Disassembly
