- 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.
PATREON
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:

Karl, it is always so motivating to see your work, thank you for taking the time to make these videos!
Thank you for the kind words! Humbled.
Finally someone who indexes the dzus replicas correctly.
If I didnt, I would never live it down at my workplace and other greenies/avionics around the world!
Another great video, great to see how things are coming along. Glad to see your design is working sweet as a nut. Keep them coming , really enjoy watching your progress. Looking amazing 👍🏻👍🏻
Awesome to hear from you Daren and thank you for taking the time to comment. I'm Back to designing again today for the throttle quadrant. Kind Regards Karl
Bless ya mate! What you've done for us all is HUGE ... thank you SO much - KEEP GOING!
Thank you for the kind words
Fantastic build. I'm really enjoying seeing it progress, especially since I can't get to mine due to the lock down. Many thanks for sharing this.
Thank you very much! we too are in lock down, but that just gives me more sim build time! Kind Regards Karl
Your start switches look very nice. Once again I am impressed by your attention to detail in your wiring practices. I really like the wax string you use to tidy the wire bundles.
Thank you very much!
Estas cañón brother. Veo y vuelvo a ver tus videos. Eres un crack!!!! 😀
¡Gracias! Genial escuchar en México!
induction loads are always a trap for new players lol! Glad you sorted it out before you burned out a USB port on the PC. Well done and I love the start switches you came up with!
LOL! It was close in burning something out! I had a sneaky suspicion that was the problem. Still going strong now, but i want to move away from using the analogue pins in mobiflight. They do strange things on startup. Kind Regards Karl
@@helimech8152 you could use an optó through a relay then into the solenoid? Or use the optó into a triac into the solenoid from just a small see rate PSU just to make sure they are completwly isolated from the rest of the machine?
fantastic job, wish all the best.
Absolute mad skills!
I'm thinking of starting this project, I've been looking over your webpage.
Great work!
Hi Randy, I think that's the Solenoid version, there's now a servo version which i much prefer as they don't require a huge current load or create back EMF!
Wow incredible job captain. You are the Best. Super neet. I'll trie to do one for my fligth school. Congrats. From Monterrey, México.
Hello Oscar from Brunei! Once again thank you for the kind words and i hope your build goes well! Kind Regards Karl
You Should be very proud of what you have built ,
We live in a world where people are more happy destroying things , to sit in your own sim and know that you built it , just looking at it i think awsome.
Hi Mick, Thank you for the kinds words. There are times that i'm very happy with certain parts, but also sometimes i sit down in the cockpit and think, wow there's still lots to do. Kind Regards Karl
amazing wiring job on th OVH! I wish that you'll never see mine :-D thanks for this vid, very detailled.
Thanks again!
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
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
Perfect karl as usual
Thank you
You have realy-realy good cockpit, 😱
Thank You Deni!
Thanks again for such an interesting video and explanation. Hope you will not finish your build soon, so we would be able to have more videos from you :D Sim on!
Hi Sergej, i really am going flat out at this end to get as much done as possible. But designing, filming and the website takes a lot time. Still having fun though and its when when people take the time to drop by and comment. Thank You.
I have been waiting for your invitation when your cockpit was ready to fly, 😜
You and me both!
Absolutely, 😃
The switch should reset at 56%. Very impressive!
Thank you
i just discover your work !!! your rock !!! next step is to make your own pcb ?
Thank you, and indeed that will be my last step creating PCBs for all the panels.
Hello again a nice project. i think better to protect the ralay or arduino board to use a diode by the soleniod ?
Hi denis, your absolutely right. They are on the leads to the solenoids. The closest point I could get them as they are self contained units
hi, congratulations for the videos, i'm building a mcp, i'm using 7 segment displays, i would like the displays to remain blank when the cabin is in cold and dark mode, i noticed that you used a precondition, exactly how to use it, for example how do i create the battery on condition?
thank you
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?
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. Kind regards karl
Inductive loads can kick the USBs off. I've had to physically separate wiring. I'm guessing my door lock actuators don't have fly-back diodes.
Hello Commander! Congratulations on the project! How did you configure the operation of the solenoid next to prosim737? I ask then when I assign the output to the Gate "Starter Solenoid" in the prosim returns the Switch from "GRD" to "Off.
I remember having difficulty with this but can not remember what it was. I think you have to assign all the switch positions for the starter to enable the gate to work. Google will know! It's where i found the answer. If you find it let me know and I will put it on the website for others. Kind Regards Karl
It just occurred to me. You want to be careful of what kind of grease you use. Some greases emit solvents that can damage plastics. Petroleum jelly aka Vaseline is a better choice.
Again amazing to see ! As I dont have a 3d printer, would you know anyone who could sell your engine switch units as a whole ?
Hello and thank you. I dont know who sells these. I can not sell them as I have no postal service here, sorry. I just received a camera tripod today that I ordered in November. That's some wait! Kind regards Karl
@@helimech8152 :-))). That is why you are such a handy man ! You cannot rely on shipments so have to do all yourself :-).
Brilliant! Can somebody tell me how the solenoid is activated? Is this something achievable with mobiflight?
Hi John, for me the solenoid was activated by Prosim software and send a signal at 53% Ng, sent to Mobiflight and output to a relay to switch from 5v to 12v. Kind Regards Karl
So many of us are wondering I think how the inside of that overhead looks. Lol...
I specifically would be interested to know where you sourced all your switches, rotataries and encoders from, as well as seeing a closer look at how you connected the wiring to what looks like the mega 2560 boards.
Hi Mark, there are several videos on the overhead and i have listed all the parts on the website, just not by quantity required. One day ill get around to it! The wiring diagrams for the overhead are also on the website. But I'm sure you probably have found this already by now! Sorry for the delay. Kind Regards Karl
@@helimech8152 I have found em since I posted this. I just need to find a way to get all the panels and hardware in the most affordable way possible. Then I’ll be working on the overhead. Just ordered the PCB board for the MCP, gonna tackle that for now.
Hello. Incredible job. I tried to download the stl files but I couldn't find it. Is it still possible to download it?
Hello Jose, I removed the Solenoid version as too many people were damaging their computers. I have now switched to the servo-operated one.
Hi Karl, which IC2 LED are you using? it doesn't look like a normal 16x2 that you usually couple with MF? would love to get the same one as you.
Hi, it can be found on this page:
www.737diysim.com/mysimparts
It doesn't come with the I2C driver. It's an extra large 1601 screen. Hope that helps, kind regards karl
@@helimech8152 great and this works with mobiflight?
Wich Sim are you using ?
Thank you so much for all your amazing videos. A buddy of mine and me are trying to find someone that has built a 737 sim so that we can try a flight in it. Why? 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..?
Hello Inferno Fury, Great to hear from you and good luck! Start Small and aim big! Hopefully someone will get in touch before you make any decisions on starting sim. Kind Regards Karl
@@helimech8152 Thanks! I really like your videos. In case you need an editor for them, I work for television and film and I'd love to help you out, editing-wise. Just an offer ;-) You can contact me at infernofuryshell (at) gmail (dot) com, everyone may contact me there. :-)
Hi Heli, how do you programme Starter solonoids with ProSim 737? to turn off when reach N1 50%
I am trying to figure it out. I am using Prosim and FDS relay card and sys1 boards.
If you cak give me little help, that would be nice..
Thanks regards Kapila
Hi Kapila, not used FDS kit as it never arrived. Contact me on Watsapp via the website and ill try to help. Kind Regards Karl
Hi do you have the STL files for the engine start in your website? I look for them but could not find them. Thanks
Hello they can be found here:
www.737diysim.com/product-page/737-start-switch-servo-operated
Kind Regards Karl.
@@helimech8152 Thank you, do you have the solenoid version as well? Thanks
I am just thinking, seeing the solenoids working fine, what about the Yaw Damper switch, that is self-cancelling as well, what do I have to do if I want to mimic that behaviour?
Good question, I have not tackled auto returning toggle switches yet. I do however, have many real aircraft ones I can use, but that doesn't really help the rest of the sim community. Something i will have to work on in the future along with the MCP AT switch. Kind Regards Karl
@@helimech8152 Thanks for your reply!
For the start: if I wanted to buy these kind of switches, what exactly am I looking for?
I don't even have the fantasy for any search terms, when using somthing like electronically operated switch I get relais or solenoids... :D
Found this thread with some interesting links:
electronics.stackexchange.com/questions/102808/is-there-such-a-thing-as-a-switch-that-can-be-actuated-automatically
And hooray: these switches exist, although I am not pleased with the price :D

@@helimech8152 And here is a datasheet of one of these:
www.farnell.com/datasheets/2145064.pdf
A switch, but pricey if you need at least two (don't recall more than that in the 737 cockpit)...

is the whole cockpit a "plastic" 3d printed one ?
Hi Dennis, not quite, but it is primairliy wood (MDF) and Plastic. Most of the panels are laser etched and then the workings are 3d printed.
What is the name of the program for setting the overhead?
I use mobiflight, Prosim & FSUIPC.
What is the Offset for the Engine starter ?
Hi Klaus, You find the offsets on the offsets page of the website. Merry Christmas Karl
Can we used normal toggle swt?
If thats is all you have, then yes
I was wondering for the view is projector, 😃
Hi Deni, I am still undecided yet for the views. I love the 4k 65" tvs. The picture quality is amazing! But of course they have bezels. I only have one projector, but would at least another, which seem impossible to find here in Brunei that do not cost the price of a large car.
🤔
you work in Brunei?
Hello Syair, Yes i'm in the gorgeous country of Brunei! Jungle to the left, beaches to the right!
Is it very humid in Brunei? Your plastic filament is really waterlogged.
Hello! It is very hot and humid here, but I have no idea how you can tell that from the video. If I leave the filament out for a few days, it's useless as it becomes too brittle to unwind from the roll.
@@helimech8152 I've heard that freeze drying it might help?
Starting to think you have Alien connections?
Chuckle, shhh.........!
