To Do:
Shown is the panel as supplied by PC Flights assembled with PC Flights supplied meters annunciators and switches.
This panel is the correct size although the width between bolt holes seems to be a bit shy of the DZUS standard (as I understand it). This hole spacing allows the PC Flights DZUS replica bolts to fit without interference with bolts on an adjacent panel.

The challenge is to backlight this panel and meters as well as to provide connection to simulator hardware.

Isometric view of completed unit.

  • Get 4 DZUS replica bolts (PC Flights and Sismo both supply them).
  • Fabricate 2 new circuit boards:
  • The first board uses surface mount LEDs to backlight around the toggle switches and annunciators. Note the cutouts to make room for the annunciators.
  • The second board is for the connectors to the outside world and also has mounts for the interface electronics.
  • Add caps to switch handles (see note below).
  • Solder LED's, resistors, and connectors to these boards.
  • The first board is mounted using the toggle switches. 4-flat-head M3 bolts are mounted to the back panel with nuts spacing the circuit board behind the back panel.
  • The connector board mounts on spacers attached to the 4 flat-head bolts.
  • Make 1 cylinder to fit around the meter with sufficient allowance for mounting LED lighting strips on the inside of the cylinder. I used 0.022 inch 2-layer actylic sheet from inventables. This sheet cuts easily and is very pliable. I cut the cylinder 1" high to keep from overheating the servos.
  • Glue a row of LED lighting strip along the inside bottom of the cylinder.

    Here is the end result.

    Circuit board with LED's, resistors and connectors mounted. The parts are not perfectly lined up, but it's what you get when hand-soldering SMD parts.

    The toggle switches and rotary switch are first mounted on the LED circuit board.

    Mount the circuit board and switches to the Fuel backplate.

    Side view of assembled unit. Note the circuit board, and led's between the toggle switches and Fuel panel. Also note the rotary switch is mounted to the circuit board.

    Wiring to connector circuit board.

    Rear View - Note the cylinders around the meter holding the LED strips.

    Switch Caps
    Lowes has a product called "White Screw Protectors" for a 1/4" screw (Hillman # 881038). These protectors fit nicely on the handle of a toggle switch although you will need to add a small cylinder of heat-shrink tubing to the narrow part of the switch shaft.
    Surface Mounting
    Most of the units use CREE CLM1C-WKW-CWBXA453. I wanted 2400mcd brightness, 4500-5650K color temperature, 20ma.
    For a 12V supply, I use 2200 ohm resistors when driving 3 LEDs in a string or 3600 ohm for 2 LEDs
