CoBox - Building blocks for a co-operative cloud

Diese Dokumentation ist eine alte Legacy-Dokumentation und dient nur als Referenz! Wir nutzen CoBox selbst nicht.

CoBox is a distributed, encrypted, offline-enabled data hosting cloud platform. It's software! But each software needs to run on a hardware platform. For your own mini CoBox cloud you can create one with ease using an Olimex A20 Olinuxino Lime 2 and some hard disk. This page describes how to do this plus some basic information for installing the software. For more details about CoBox in general please see the dedicated project page of the developers at https://cobox.cloud.

Possible feature enhancements

  • self-printed bolt spacer could be replaced by a distance bolt M3x16 mm

Production steps

  1. print parts (base, top, cylinder)
  2. lasercut parts (with protection foil) → top and back plate, base plate
  3. make thread into cylinder
  4. smooth edges at printed parts (using cutter knife or sanding paper)
  5. remove support material on printed parts
  6. create coutersunk shapes in lasercut parts
  7. remove protections foils
  8. screw together printed top base with lasercut plate sing 4x M3x4 screws
  9. create sticker with Plotter
  10. put sticker on top plate (must be screwed together before!) → sticker will hide screw heads
  11. add missing parts: screws, bolts, rubber feet
