Overall System Requirements
Mechanical
- All major subcomponents (Main Instrument Panel (MIP), Left Console, Right Console, etc.) shall be capable of movement through a standard 30-inch-wide interior residential door.
- All major subcomponents shall be able to be assembled and disassembled from each other with minimal hand tools for transit purposes.
- System will be designed to occupy a minimal overall footprint, with the exception of major accessories, including, but not limited to, PC or LCD/TFT/TV/projector visual outputs.
- Minimum tooling required shall consist of:
- a hobby-grade 3D FDM printer (Prusa i3 MK3 or equivalent.)
- a hobby-grade resin 3D printer (Anycubic Photon Mono or equivalent.)
- a hobby-grade CNC Router (XCarve 1000x1000 or equivalent.)
- common hand/power tools (Drill, screwdrivers, sanders, wrenches, ratchets and sockets, calipers, tape measure, ruler, square, marking devices, etc.)
- basic electronics assembly equipment (multimeter, soldering station, magnifier (optional), desolder vacuum, desolder braid, solder, flux.)
- All components shall be designed with a major consideration for ease of future maintenance.
Electrical
- Input electrical requirement: 120AC @ 60hz.
- Overall system shall run on +12V, +3.3V, and +5V buses (with the exception of major accessories, including, but not limited to, PC or LCD/TFT/TV/projector visual outputs.)
Panel Requirements
Panel Stackup
Panels shall consist of the following plys:
- 0.125 (1/8) inch clear acrylic (Backplate)
- 0.1875 (3/16) inch clear acrylic light plate (Light Plate)
- 0.0625 (1/16) inch Rowmark Ultra-Matte, White on Black (Legend Plate) (Equivalent 2-ply rotary engravable materials may be substituted as desired.)
Panel Construction
- Light Plate and Legend Plate shall be bonded with Weld-On #4 or equivalent, then painted IAW FED-STD-595, 37038, Lusterless Black, prior to engraving.
- Backplate shall be painted IAW FED-STD-595, 37038, Lusterless Black.
- Bonded Light and Legend Plate assembly shall be assembled to the Back Plate with #6 screws, unless otherwise required for specific application.
- Backplates shall be installed to consoles with #8 flathead screws with printed DZUS head replicas.
Panel Typography
- Legend Panels shall be engraved to the minimum depth as specified by the material manufacturer.
- All fonts shall be Gordon Medium Bold or Gordon Medium Condensed Bold as required for specific application.
14-point sized font shall be standard, increasing and decreasing as required for specific application.- On panel revision, the following font sizes shall be adhered unless deviation is required for specific purpose:
- Panel Label (ECS, SNSR, etc.): 21pt
- Main Label (MODE, TEMP, etc.): 17pt
- Position Label (ON, OFF, AUTO, etc.): 14.5pt
Structural Requirements
- Major structural components shall be fabricated from .75, .50, and .25 MDF or birch ply as required.
- Any component designed to bear the weight of a human shall be able support a 250 lb static load.
