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
solid, custom
may look also unprofessional, like a building kit
design without screws ⇾ https://hackaday.com/2013/02/27/acrylic-enclosures-use-integrated-clips-to-do-away-with-fasteners/
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)
Off-the-shelf Cases
