737 Tiller & Operating Mechanism

This was a fun video to create, short and simple! The video shows the creation of the 737 Tiller and operation. It's 3d printed and works amazeballs!
The fun comes halfway through the video, P3D has given me a serious beasting! It refuses to load! Takes over 2 hours to load Gatwick and sucks like a 1980s MTV music video looking back on a past era.
Then the magic happens! Im taxing around Gatwick, P3D comes to life. Planes appear, textures appear and generally, it stops sucking!
One more video to come in short order! The building of the display and graphics. However, MSFS is just too gorgeous to show in this cockpit video.
It's in a different league!

[@stephencampbell9886]

You should put this in a shipping container mounted on hydraulic jacks!

[@helimech8152]

Hi Stephan, I think that's the million-dollar question that everyone has. That would be the ultimate dream. But for me, this is just a hobby and the sim will remain a fixed base. Over the years I have thought about making a moving base unit. But for the 737 is not currently an option. The last time I looked at the hydraulic jacks they came in at around 6000-12000 pounds each, to which I would require 6. Then you have all the equipment required to run and control the unit. I really can see why the real simulators cost so much. To make things even harder, where would I put it? This thing is already massive and I dread the day we have to return home to our little house in the UK. I am currently designing a heli sim, which is lightweight and hopefully, electric actuators can be used. But that's a future project. probably a bit more of an in-depth answer than you were looking for, but I have thought about it many times over the years. Kind Regards Karl

[@stephencampbell9886]

@@helimech8152 Thanks Karl! There are a lot of wires to connect everything ! I wondered whether you could connect all the devices via network cables and UDP protocol. ipMidi allows you to connect MIDI devices over a computer network. It doesn’t use TCP/IP but instead uses Multipacket UDP which gives it a lot more bandwidth than standard MIDI. If you were to use a UDP layer, you would almost want it to be invisible to the existing client/server software you are using.

[@sundar999]

Inspirational video again, thank you Karl! I will use a standard European 75mm drainpipe for the yoke column since Markuspilot says it is 76mm in the real NG. I hope to find a yoke neck that fits the 75mm or a 3D print file for the same:)

So for the time being and to get in the air on both P3D and MSFS2020, im going to get the Captains yoke done first. Once the parts arrive, like carrier bearings, inline turnbuckles, sprockets and chains, then i will convert to dual yoke setup. Also, been thinking a lot recently on the centering mechanism, force feedback and force trim. Hopefully i can get this sorted on the captains side and use is also for the FO side. Kind Regards Karl

G’day Karl, Fantastic project you’ve made - your wife must be incredibly patient! Your design is just an amazingly simple yet effective solution. So thank you! However, I’m wondering about your pedals? All of your other designs are fantastic, so I’m obviously a bit intrigued what you use. I’ve designed some pedals loosely off the 787, but they aren’t the pedestal style. I’m going to try and adapt your tiller mechanism for the centre and sensor pickup, I think it would be perfect. Perhaps with some increased scale for added strength. Finally, you mentioned using a capacitor to remove the jitter when calibrating. Can you explain this a little more in a video or blog post on your site? I’m sure you would do such a fantastic job at enlightening us all. Best regards down there in Brunei.

[@lestaylorB737sim]

G'day Karl, Two little snippets for you. Check that you have not got your tiller active in the main FS program ( PrePar3D) and FSUIPC. There is conflict if you try to calibrate with both active. It causes the jitters you mentioned. assign in one only. When you assign the "card" in the P3D configuration ....move the tiller so you get a reading on the top bar, the just hit the "A" box next to the assignment box and hey presto ...it finds your Bodnar card assignment automatically. I will try to put something up on my channel soon.

[@helimech8152]

Hello Les, Great to hear from you again! You wouldn't believe the hassle i have of deselecting all the controls in the different programs! You are completely right, if theirs a duplicate control, we spend days trying to figure out why we had no elevators despite the PROSIM showing in the config page all was good. In the end i had move the Elevator control from Prosim, and move it to FSUIPC. Tony that came to have a ho in the sim, had to bounce the aircraft off a hill, or house to get airborne. That flummoxed me. As always Les, Thank you for the advice, it really is appreciated. Im on holiday with my wife Helen right now, but am determined to get the control column sorted next! Kind Regards Karl.

Hi. It is immediately obvious that you are a trained avionics/aircraft tech because of the way you wire it up - lovely. My degree was in avionics so I have done this sort of wiring before and it is mega rewarding to see it all beautifully loomed and laced. Question: have you used a VR headset in your 737 simulator? I know that kinda defeats the point of building such a faithful, accurate cockpit, but I want to get back into the air soon (PPL & IMCr holder), and would like to use the new MS flight Sim (or maybe even Xplane11) to practise cockpit checks/memory items, but It is much, MUCH more realistic to have a real instrument panel. I'd really like to be in a VR headset, but able to operate switches on a real instrument panel - do you think VR headsets (specifically the tracking technology) would present an accurate enough virtual panel that the panel switches would feel exactly where the VR picture shows them to be? I am kinda suspecting that's a 'no', but I'm asking in case the tech is better than I'm giving it credit for? Sorry for the long question!

[@helimech8152]

Hello Edward, sorry for the delay in getting back to you. Thank you for the great comment. I haven't tried MSFS in virtual reality, but I know a lot of people cant get enough of it. Is it good enough to carry out cockpit checks and muscle memory programming. Really im not sure. But i would hazard a guess to some extent. But nothing is going to beat sitting in a full sim cockpit to practice just that, especially when there's no consequences when you get it wrong. The good thing about Prosim is the included instructors station, which tells you what ha been missed or needs to be completed as you go through the checks. Prosim however, is type specific, where as MSFS in virtual reality, you download the aircraft type and your ready to go. I think what I'm trying to say here, is that i have no real quality advice to give here! Either option can be a costly experience to start out with! Kind Regards Karl

I have got to say what a GREAT SIM in every way m8e. Whats your view on Air Manager with touch screen buttons? I am at the cusp of either building a fully functional 737 home cockpit like you have based your sim on. I have got FS2020 as you can imagine. Do you think I should use Air Manager for all the functions to get the same overall feeling of the sim?. The noises are important as well yes? I have 400mm square Creality CR-X dual colour FDM and Resin Photon printers but the costs can be immense when you start adding up the costs of the buttons/interface boards and god knows how much MDF you have used yeah!. Your comments are welcome on that. I think you in IT like me yes! I come from the 8bit days 20yrs ago and building a home cockpits would have cost £30k and 5xCRT monitors/computers... You get the point. I have tried before with an AutoPilot Self Contained (Blackbox solution) with other bespoke hardware which cost £500+ from Australia for AP and list goes on. And other add-ons which in all via FSUPC was clunky.... Look forward to your reply. Regards, Andy ps.
