STRATEGIES To Do:

Shown is the panel as supplied by PC Flights assembled with PC Flights supplied meters and Push Button.

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.

KIT BASHING

Isometric view of completed unit.

Get 4 DZUS replica bolts (PC Flights and Sismo both supply them).

Fabricate 1 new circuit board:

This board uses surface mount LEDs to backlight around the push button and also contains the connectors to accept the 3-servo connectors, wire to the push button, and connect to the simulator electronics.

Solder LED's, resistors, and connectors to this board.

This board is mounted using the same mounting bolts used to attach the pushbutton cover to the backplate. Add a nut between the backplate and this circuit board for clearance of the LEDs.

Make 2 cylinders to fit around the meters with sufficient allowance for mounting LED lighting strips on the inside of each cylinder. I used 0.022 inch 2-layer actylic sheet from inventables. This sheet cuts easily and is very pliable. I cut the cylinder 1.5" high although I should have cut it 1" to allow better cooling of the servos.

Glue a row of LED lighting strip along the inside bottom of each cylinder.

Circuit Board

Circuit Board Mirrored

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.

Side view of assembled unit. Note the circuit board, leds and connectors.

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

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
