    I would also say that those prices is a bit too much, i would love to help you, but i live in Denmark, and then there is the Postage / Shipping Price.
    So it will no doubt be cheaper for you if someone here on the forum, that live closer to you could help you out



      hey guys not sure if anyone has asked or done this before but i have spent the past few days trying to get these plans to print on a large format printer so i can use them as a template to cut out the wood. i have no idea what im doing when it comes to this. i use draftsight to open the files but i try to convert to pdf (the printer cant use dxf) it cuts some off or it is way too small any help would be great also what is used for the front dash in this pit

        That's pretty high.... I'm not going to lie, it takes time finding someone who not rip you off!

        Maybe $500 for the seat cut max...


          I took my plans into a local school and had them cut on a laser cutter, and I made a donation to their current fundraising. The compromise was that the max thickness of ply it would cut was 9mm. This actually worked fine as long as you use interior ply. I think it cost £60 in wood and £150 donation.

            I'm back baby!

            After many years on hiatus, I am restarting my pit build. I have a new, simplified set of plans based on a modified version of Deadman's outer tub, and a complete redesign of my original inner consoles. This new pit should now be easier and cheaper to build, and more accurate in several places.

            My first modification was to split the tub lengthwise into 3 parts so it can be disassembled and fit through a standard doorway, as well as providing a hinge point for swinging the sides open to enter and exit the pit without climbing. The next modification was the shorten the pit on both ends so that it fits within a 5ft. x 5ft. profile. The pit measures 60" x 53.75" with some spill-over from the seat and HUD frame. I also lowered the pit by a couple inches and plan to use 2x6 lumber for the floor rails. Finally, I cut corners (literally!), so that I could snug the whole thing up to a corner of my room, get the screens closer, and still be able to swing the side open by about 15-20 degrees.

            My inner side consoles were redesigned to do away with the cross-sectional ribs and go with a mostly longitudinal structure, inspired by the Lynx design. This simplified the whole thing, especially around the Warthog throttle mount. The whole front panel structure was also redesigned to replace the aluminum angle construction with 1/2" plywood. I left room behind the center pedestal for my new TM TPRs.

            For visuals, I was thinking about starting with 3 vertically mounted TVs on a custom 80/20 hinged frame. I also have an Oculus Rift, and although it will probably not be my preferred way to fly, the immersion is undeniable, so I will be experimenting with VR in the pit as well. The ultimate setup, I think, would be to use 3d glasses to get a bit of both worlds.

            I'm sorry for the terrible renders, I'm still using Sketchup for this project and it doesn't seem to have a decent renderer anymore.


              CDU Build

              Here are some shots of my CDU build. The guts are driven by a raspberry pi and some custom software that is available on my github here I will post a more complete tutorial IF there is enough interest, on how to turn an out-of-the-box raspberry pi into a working CDU using my interfacing solution.

              In a nuthell, data is extracted with DCS-BIOS and sent to a Pi running NodeRED. The NodeRED "node" is the heart of my interfacing solution, and there is logic built into the software running on there to parse the DCS-BIOS stream, filter it down to just what is needed, and transform everything out into MQTT messages. The MQTT server (Mosquitto) also runs on the Pi. Then, all interfacing from the NodeRED hub to the panels happens via MQTT messages over ethernet. I will eventually release all of my interfacing software, hopefully as an official "alternative" set of libraries under the DCS-BIOS project.

              But before I go into any more of that, here is my build.

              I still have some light bleed to resolve, and I will be remaking the buttons, but other than that, the dimming is fully functional in the sim. It gets a bit too bright at the highest setting, so I will limit the max PWM value in software.

              The bottom of the case shows slots for Molex power and the Raspberry Pi SD card.

              Only the ethernet port is used for interfacing.

              The back of the perf board, mounted to the base plate shows the crazy amount of soldering. Somehow I managed to get it right the first time, phew... The male pin headers connect key rows and columns to the MCP23017 board. The female pin header connects the LCD screen to the RPi. The wire labeled HDD connects the LED back lighting to the dimmer module.

              The buttons feel fantastic, with no wobble and a nice long travel, but they look like hell. I need to find a better way to make them. The N,E,S,W,5 and MK buttons are built a bit taller than the rest.

              Most LCDs at this size are 3.5" or 4.3", but neither are suitable for this panel. This screen is a 4" made for the RPi, which allowed me to make fewer deviations from the original design with my button positions. I ended up with a very close replica in the end. In order to get perfect alignment of the LSK buttons with their corresponding row on the LCD, .1" spacing would not work, so I had to do some tricky off-center positioning of the hole for the key cap to sit on the buttons.

              Shots of the top of the perf board with and without the light plate.

              The innards of the case shows the Pi with a pin breakout board, and above it the power input board with MCP23017 attached.

              Over top of the power board is the LED dimmer which receives PWM signal from the Pi. The Pi itself gives out a very inconsistent PWM signal and cannot dim the LEDs directly (I originally tried this through a MOSFET). The dimmer board smooths out the Pi's signal and sends its own clean PWM to drive the LED strips.

              The light panel is made from laser cut styrene sheet, and sprayed black on the back side. Light strips and wires are held on with the help of some CA glue. You can also see clear acrylic triangle pieces which act as a fulcrum for the rocker switches. When one side of the switch is pressed, it's not possible to press the other side.

              Some more shots of the individual pieces.

              The bottom of the perf board connects rows of the key matrix, and brings them up to the top row of header pins. There is a pull-down resistor connecting each row to ground so the GPIOs do not float. The MCP board does not have built in pull-up or pull-down resistors.

              The top of the perf board connects key columns. There is a diode at each button to, so I am able to press unlimited simultaneous keys and each one is picked up correctly. One important thing when soldering up a button matrix like this is that no two buttons should share both the same row and column with each other.

              Well that about wraps it up. My next post will be a video showing the screen and buttons in action with the sim.

                Nice, how do you adapt the raspberry pi screen to run off DCS?


                  Hello y2kiah, very impressive work you have done.
                  I used your former plans to build my own cockpit and it worked very well. Thank you for that.

                      CDU data is extracted with DCS-BIOS and then run through my NodeRED program. From there it goes to the Pi as MQTT messages over ethernet. The CDU display, buttons and backlighting is run from a single python script, available on github I added some setup instructions to the project to further explain how it's all set up.


                        Very nice CDU build you have gotten there sir. I seem to recall from the C-130 CDU I have got that they have placed a small piece of foam ring around each button, which then seals to prevent bleed light.

                        Looking forward to seeing more progress on your pit sir.



                          CDU Demo

                          Thanks for the tip Hansolo, that would help for sure. I may try that on my upcoming UFC build. I fixed some of the CDU light bleed with touch up paint on the buttons and electrical tape around the screen perimeter, and the pictures actually make it look a lot worse than it does in person, so I'm pretty satisfied with it for now. If it works out for the UFC, I'll probably come back and work it into the CDU.

                          Here is a demo from CDU boot to shutdown:

                          0:00 - power-on and boot
                          0:43 - waiting for telemetry
                          0:50 - start simulation
                          1:18 - back lighting
                          2:40 - go to menu (hold NA1 for 5 seconds)
                          2:56 - key matrix test
                          3:28 - quit sim
                          3:35 - shutdown RPi


                            Any further progress on this build?
