Kiosks 2.0


Components


Computer

The computer in the 2.0 kiosks will not have its own enclosure. Instead, the frame of the kiosk itself functions as the primary enclosure. This has many advantages; among them a unified cooling system.

Preliminary hardware:

Hard disks:

Under consideration:

Base station

There are a number of concerns with integrating off-the-shelf parts, as there is some variability of size amongst both ATX PSUs and microATX motherboards.

For the PSU:
  • Standard dimensions are 150x146x86mm
  • The 150x86 dimensions are fairly static. Our reference PSU is very close on these dimensions.
  • The 146mm dimension (approximately how "deep" the PSU is) can vary much more. Our reference is larger, but not by much, say 5mm.

For the motherboard:
  • Standard dimensions: 9.6in x 9.6in
  • Reference: 9.6x7.6
  • Variation can occur in both dimensions
  • Our design can currently support at most 9.6x8.35in motherboard, assuming that we want to plug in cables with headers no longer than 2.25"
  • Motherboards for lower-end processors fit this quite easily; high-end processors (Core 2, etc.) almost universally utilize all the space.
  • There are sufficient boards on the market of our current processor type that meet these demands

Intake size:
  • Our fans have an intake area of ~1.25*1.25*pi = ~5 sq in.
  • Assuming an intake width of 5.5 in (1/2 in border on either side) and a grill that obscures approximately 1/2 of the area, the height required for the intake is approximately 1.8 inches.

Modifications

  • Move data drive to ceiling of peripheral side
  • Add holes ad slots for keys and locks
  • Move motherboard holes away from edges
