  • Hello from Brunei, In this episode, I apply power to the 737 cockpit and sort some of the errors that show. Moving onto the construction of the 737 start switches and installation.

    A couple of people have asked if I have a Patreon account, I finally got around to creating one. If you fancy showing support for the videos and build, and I have switched off advertising for videos now:

    Guys pls You don't need that much arduinos, just Buy multiplexors or shift registers, is rlly easy to use and You can expand 6 or 8 i/o with 1 analog pin, Even You can expand analog pins. More cheapy

    • @helimech8152
      @helimech8152  3 ปีที่แล้ว

      Hi Ulises, Im guessing your using X plane and probably SimVim or have a good knowledge of programming. P3D and MSFS both require FSUIPC and mobiflight. Mobiflight doesn't accept multiplexers or shift registers to keep things simple. People on my site range from 8 year olds to senior citizens, i struggle to keep up with all the wiring requests and fault finding as it is. Adding another 5 Euro Arduino mega is much simpler than asking another person (usually someone who has zero experience in electronic theory) to create the circuitry/wiring for mutliplexors/shift registers. For analogue uses, i highly recommend the Arduino Micro Pro, for 3 to 4 Euros each. Thank you for taking the time time to comment, Kind Regards Karl

    Again a well designed piece. I wish, I could model as good as you in Fusion. I'm shocked a little bit that you have to do so many settings concerning this could and dark feature. I would have thought that prosim has modeled this basic behavior. Why should any light be on in the cockpit when the main power is off?

    • @helimech8152
      @helimech8152  4 ปีที่แล้ว

      Hello! I never thought of it that way, and indeed, perhaps when the software becomes more arduino friendly, this will happen. But I don't mind putting a few extra clicks in here and there. I also think it might be mobiflight glitch too as I have so many cards. Random displays will come on when I start mobiflight. I have to run, stop and run again to get everything perfect.

Not just for fun, we are deciding wether or not to build a simulator for ourselves like this, so we would LOVE to enjoy the experience and decide on that.. But we are based in The Netherlands, and renting a sim flight at a company is 150 bucks per 30 minutes flight, and not even with startup, just on the runway and ready to get in the air... So if anyone is in, or near The Netherlands with a sim, give me a message..?
