I want to build a wearable computer around a raspi and this 1cm wide CRT i salvaged from a camcorder.

Case

  • Needs notching/interlocking connection from system to batterypack
  • This?

Battery system


  • will connect to the raspi with a 3 pin connector (+v, 1-wire data, gnd)
  • there will be two 3 pin connectors to swap batteries while staying online (or maybe just run on two batteries)
  • on raspi there will be a attiny (or something) on uart0 to interface with the 1-wire
  • raspi will get an internal 2a 5v regulator (with display woohoo)


Screen

  • crt will be mounted on cap
  • beamsplitter will be mounted under the cap, reflecting visual into eye
  • lenses will be needed between beamsplitter and crt for focus
  • beamsplitter will be mounted on a swivel, and rotatable for higher flexibility
  • another 3 pin connection : +5v, composite, gnd


Input


  • keyboard nearly finished...
  • add a mouse? maybe a trackpad on top of the wrist, or a mini joystick on the thumbpad?

Have

  • Raspberry Pi
  • mini CRT (second found, first seems dead now :s )
  • teensy (for usb keyboard emulation)
  • wrist frame (soon on thingiverse)
  • Beamsplitter (ordered)

(on the way)

  • good power source
    • needs a proper bms! gauging and maybe built-in charging?
    • just needs 5V! but a lot of amps ...

Want

  • magnifying lenses
  • better case
  • some wireless card(s) on usb ?
