Basic Capabilities:
- WiFi
- Local SSH identity (hardware backed?)
- Mosh (wishful thinking)
- Text mode interface
- Batteries with decent life
- Good keyboard
- Local UI for some configuration options
- Non-trivial fonts
Electronics:
- Application: Teensy 4
- Very many hertz
- Well supported by rust
- Easy to get both the Teensy stick and the dev kit
- Network: ESP*
- Vendor firmware for wifi coprocessor (AT and something fancier I can't remember the name of)
- Possibly keyboard processor
- Offload matrix scanning and maybe reduce wires between halves
- RP2040 would mean circuit python keyboard
- Atmel/PIC/etc would probably mean less power usage
Keyboard:
- MX
- Layout based on X-Bows Crystal
- Mostly because it's vaguely ergonomic while staying flat
- Also, the Crystal variant uses standard-sized keycaps
Screen:
- eInk has insufficient refresh rate for interactive TUI
- Plus, fancy shell setups benefit from color
- So, probably something traditional
- About 10"? Depends on final keyboard size
Software:
- Rust
- Async?
- Use existing modules when possible
- Rich font
- Emoji
- A few languages
- Icon glyphs (a la powerline, devicons, codicons)
- Local TUI to configure WiFi, SSH settings, other?
- Instant boot, instant shutdown
Case:
- Honestly, don't know
- Big chunky hinge maybe?
- Got a goth magical girl keycap set I was thinking of using
- Leather?
- Strap?
- Short but thick, kinda the hot dog of laptops?
