    Hi guys!

    So ive finally decided to go for this and ive got most of the parts. It will be based on the berginsons and Rift flyers builds https://www.xsimulator.net/community/threads/riftflyers-g-seat-project.8418/ I will build the seat in wood. I just need to borrow a saw to cut the side parts. I live in such a confined space at the moment that it will also be my comfy chair with wheels and some extra pillows in that mode. Think Tokyo living spaces.

    I have started wiring up some ardunios for testing with a pot and the motors and i hope to start building the actual seat tomorrow. I still need some bearings for the wooden wheels so that will probably take a week or so. Id love to see a tutorial on exactly how but i think i got it correctly

    Ive been thinking of connection the pots in a direct linkage instead of using gears. I have a 3d printer so i can do either if i so wish. Perhaps someone with more experience in this could say something about the resolution the pots would need. Perhaps a 2:1 gear ratio or is it fine with direct?

    The rest is a bit trial and error. My motors are a bit on the small side but i dont weigh much.

    So far i have
    4x motors
    2x Ardunios and 50 amp controllers
    4x pots 10k ohm
    Wiring
    Wood
    Wood wheels to be made, have access to lathe. Need bearings
    All the linkages and rods.
    Lots of drilling holes, learned how to sharpen bits!

    I need to get a hold of the link arm you see one that one motor (the black plastic) in metal as they didnt come with one, any tips on name of those are welcome!

    Didnt have a chance to edit so when i ask about tutorials thats about the Ardunio wirings. just so there is no missunderstandings ;)

    So i couldnt sleep at all so i went on building instead. I think i will be able to build most of it today and perhaps even start the electronics. At the very least unless i hit a snag i should do most by tomorrow. I have decided to skip the wooden wheels for now and add that in later.

    I got some new tools and some wheels for the seat. While they do have brakes on them im going with two in front and use rubber on the back so im sure it wont be moving around.

    Had a bit of a setback with both my drivers being bad so ill have to wait for new ones. This rather sucks haha

    In the meantime im finishing the build. My biggest cost is actually the tools to make things but luckily i can borrow some too. Like this lathe here to make wooden wheels. You can never have to many tools of course!

    Apart from the tools the wood so far have been scavenged and about 25$ for the frame panels, not much at all! Since the wood one is mostly an experiment to see what work for me Im always on the lookout for a used car seat or perhaps even using my DxRacer and building bottom and back box for it, as compact as possible but might be a mix of servo and wiper motor's. This will be a lot easier with some experience with dimensions and such

    So i decided i just wasnt happy with the previous stuff. Im lacking the saw's i need to get a proper straight cut and it felt a little wonky. Instead i just decided to start on my Dx racer chair and it turned out to be easier (so far) than expected.

    Here's the general idea. The wood panels are actually very sturdy attached like this. The PSU and all wiring will be in a box under the seat. I may build a box in the back later but for now it will be open but with the cabling hidden as much as i can. Thankfully the material i already had was a perfect fit! Ill get aluminium panels to save space for the flaps later. I got a machine shop 10 minutes away where i used to work so i should get that cheap.

    PS this is my office chair too so im currently backless haha!

    As this will mainly be for flight sims im looking to get the most realistic G sense. I maybe actually use paddles (for better ground takeoff/landing noise) and a pneumatic system thats driven by the same motors. its an idea but will see on torque and stall

    Getting a little further in my build. The backrest is essentially complete and working but the final position of things are not decided. I 3d printed some brackets for the pots but ill be replacing these with halls sensors later on. Ill use the same brackets though.

    I am skipping the wheels for now as my tools just isnt up to the job of getting a true cut and holes so that will wait. I also have 2x sabertooth x32 on the way and may get another motor to do the belts for a more realistic feel.

    One thing that bothers me is that the pressure you get from the flaps just dont feel right so as a go between i think i will cut them in half and use a hinge. That way i will get more hug feel from the pressure.
