Update:

The new parts for Helm arrived last week, so I was able to measure, design, and cut the engine and attitude panes. Looks like the slider for warp is going to fit, so it's in the design. Here is a photo of the test fitting with the new parts.

Everything checks out, so it's on to finishing the frame and wiring next.

In terms of wiring, this is the most ambitious of the panels yet in terms of real estate used on the Teensy-LC. I have only two pins left unused. Here is my planned layout in terms of pin assignment.

I look forward to sharing the results!

Very nice! I look forward to seeing it come together.

Update:

Helm is coming together slowly but surely. Since it is a major feature of this panel, I want to share some more details about the dynamic lights (as opposed to the on-all-the-time lights).

For reference, Weapons had two dynamic lights: an LED for "ARMED" and an LED for "LOCKED":
IMAG0617 - Copy.jpg 
These indicators were made by cutting out a rectangular hole in the transmission and diffusion layers and replacing the hole with an isolated transmission and diffusion layer just larger than the text, plus room for an edge-lighting LED. This arrangement worked well for a large illuminated area with relatively diffused intensity.

For Science, the 3x3 array of LEDs form a dynamic display, capable of representing various controller states with different patterns.

Science MFD - Copy.png 
Because of the small size of each square, it was possible to direct light them using the high-intensity LEDs (run at lower current) to create a bright effect visible in any lighting.

IMAG0647 - Copy.jpg 
To make each light perfectly square without light spilling over into the adjacent squares, I cut a lighting shield from 1/8-inch MDF using a side-cutting drill bit. I am using the same concept for Helm. The biggest difference is that there are now 22 dynamic lights, grouped into three different shapes (circle, triangle, and character). The circle and character shields were cut with regular drill bits, giving a clean final appearance (triangles not so much):

IMAG0711 - Copy.jpg 
Any misalignment will be compensated by the transparency film, which has the crisp, laser-printed lines on it. The center two shields (each with six holes) are part of the same assembly -- the small holes are for the LEDs to fit, the large holes are placed above it as follows.

First, I needed to sand down the tops of the LEDs, because they are too tall to fit between the top and bottom acrylic layers otherwise:
IMAG0716 - Copy.jpg 
Next, the LEDs are placed in the MDF shield assembly:
IMAG0721 - Copy.jpg 
Finally, the space around each LED is filled with hot glue. The hot glue has nearly the same refraction index as the LED housing, so it neatly repairs the tool marks from the sanding and also distributes the light to fill the entire shield opening. This allows me to take the light directly from these narrowly-focused high-intensity LEDs and spread it out over a slightly larger area. As seen from Science, the most intense light is still concentrated in the center, offering stronger contrast than for weapons.
IMAG0729 - Copy.jpg 
Over the top of the MDF shields with hot glue, I place the color filters:
IMAG0730 - Copy.jpg 
The panel is now ready for final assembly and wiring:
IMAG0731 - Copy.jpg 
There has been a lot of good discussion about how to create various lighting effects in the forum. I hope this contribution has some useful ideas for others.

Looking great! I had plans to make backlit controls for my stations. your side lighting idea is really neat and one I may have to utilize.

I must agree with all the others.  This is turning out very nice looking.

Thanks everyone for the kind comments. I am very glad that these controls turned out so well.


Update:

Helm is now fully operational:
IMAG0763 - Copy.jpg 

It includes lights for impulse and warp:
IMAG0765 - Copy.jpg 
It also includes a heading selector in addition to the joystick-style controls for yaw and impulse speed:
IMAG0767 - Copy.jpg 
It took some time to wire up everything as there are 5 analog inputs, 10 digital inputs, and 10 digital outputs to create the thumbstick/slider controls, button matrix, and LED matrix, respectively:
IMAG0757 - Copy.jpg 
So far the interface with the game seems to be working smoothly. I will need to do some more testing.

Thanks! Here is some more detail showing how the LEDs are mounted. It took some trial and error, but I am now generally pleased with how the effect worked out.

The control panel style I am emulating was definitely back-lit. The classic starship console looks like a light box (or light bright) for that very reason. I was hoping to get something that lays flat and requires a minimal amount of hardware, hence the edge lighting. Fortunately, the modern super-bright LEDs are up to the job.

Wow! That is looking really good. I can't wait to see it at Armada!

Im liking what you have done with the controls. very unique way to configure the interface and it looks like it will be very natural to use. well done. what did you use as the knob for the slider? is the knob on the heading control the same thing?

Thanks!

The knobs for the slider and heading control are both cut from 3/4" hardwood dowel rod and painted reflective silver. The knobs are formed to the control stems using hot glue inside the mounting holes. I put black electrical tape on them for grip surfaces. I think the color scheme goes well with the rest of the design. However, these particular knobs ended up looking a bit lumpy because of how I sanded them. They come off easily, so I may just try again with new ones.

The unpainted knobs are also visible near the top of the frame in some of my progress photos. They look like wooden Cheerios.

Where did you get the slider? Can you link to the source?

 

Thanks in advance!

 

This is a great setup!

Thanks!

I bought nearly all the parts new as I did not want to try to get odd-fitting parts together throughout the project. Fortunately, there are some good-quality parts out there from the electronic hobbyist websites at prices that fit my budget for the project.

Here's a list of some of the key parts:

slider: https://www.sparkfun.com/products/9119
rotary encoder: https://www.sparkfun.com/products/9117
bright-white LEDS:  https://www.sparkfun.com/products/9850    (Helm dynamic lights)
  https://www.adafruit.com/product/754    (all others so far)
buttons: https://www.adafruit.com/products/1010
thumbstick: https://www.adafruit.com/products/2765
controller:  https://www.adafruit.com/products/2419

For LED projects on our Artemis bridge build (check facebook for HMS Artemis Bridge Simulator for photos) I primarily use superbrightleds.com

BangGood.com has also been a great source for components, you justhave to wait for them to get in from China.

Thanks again for the sourcing, I found a 10k slider for a couple bucks on Ebay, may order a few NOW...

 

Thanks again!
