Hardware Casing for Nodes (2020)

Deprecated / shelved! Current lasercut case is in main repo

Constraints

  • nodes can vanish, wander

    • fixate

    • keep inconspicuous (under desk an option?), make it look official / blend in

  • nodes can spook new people in the same office

    • must look professional, official

    • be transparent about the function (inform current people in office, but also use sticker to provide a FAQ-Website

  • must support cooling (direct sunlight, proximity to radiator)

    • convectional cooling would be the easiest

  • must contain

    • BBone with shepherd Cape (75 x 55 x 25 mm)

    • POE-Converter (81 x 55 x 25 mm)

    • Target nodes (20 x 30 x 4 mm) - orthogonal on capelet or in direction of longest edge of capelet)

    • < 20 cm Network cable

    • power-connection

    • USB-Stick (45 x 20 x 9 mm)

    • opening for one RJ-45-Socket

  • must be transparent to RF

  • input Marco:

    • open and transparent is fine and wanted (!)

    • boxy is ok

    • preferable hard mounted to the wall with just one cable attached

Layout

  • flat on one level

    • X: 75 + 45 + 30

    • Y: 55 + 55

    • Z: 25

    • 150 x 110 x 25 (412 cm²)

    • pro: clean,

    • contra: harder to cool, less optimal RF-performance (antenna near to ground)

  • Stacked

    • X: 75 + 45

    • Y: 55

    • Z: 25 + 25 + 30

    • 120 x 55 x 80 (528 cm²)

    • pro: more boxy, would better fit on top of the cable canal

    • contra:

Solutions

  • 3d-Printing

    • flexible and custom case

    • way to expensive for 30 Nodes

  • Casing in laser-acrylic or plywood

  • off-the-shelf case with custom front

    • can look professional

    • you have to take what the market offers

    • way around custom front is: just include an opening for the cable with a gasket (or right there where two halves meet)
