    Hi Everyone,

    After reading through these forums for a number of years saying to myself one day i will build a motion sim, I'm finally taking the plunge!

    I've built several static sims over the years which i will try and dig photos up of to show everyone

    Have also built things like diy Cheap custom shifters and handbrake, button box, just having a go and making things work haha

    So my plan is a 2dof with traction loss, taking insperation from Noorbeast's, Avenga76's, Halloween2go, Blame73's and P00ky's combination of ideas

    So far i have already:

    Arduino Uno x1,

    Md30c rev2 X3 Motor controllers, Have started testing using Blame73's updated code had a few dumb moments last night but managed to work it out and had a succesful test on with motor motor

    6127V1A180L.5FS X3, i bought these hall pots as Noorbeast mentioned them and i was racking my brain trying to work out what direction to go in so that made that simple lol

    Logitech g27 wheel and pedals, Shifter gave up years ago, Will replace this at some stage not sure what with yet

    Arduino leonardo powered button box, Also controls my custom H pattern/Seq shifter

    Generic racing seat that is comfy and in good nick still

    Also Ordered:

    Rose joint 8 pack
    4 point harness
    8x skateboard wheels with bearings

    Annnd:

    About to order a cheap usb handbrake as i found one that i cant even get the parts to replicate for the price lol

    I need to find some motors now

    there are a few options i can go with but they vary from around $600 for three to my door to around $850

    not in a rush for that part atm as i dont have the cash to willy nilly throw about haha

    so i want to nail the motor choice before i even think about a purchase, I'd like to go with Avenga76's units but i dont know if the md30c will suffer the same issue that his Jrks had and i dont want to do this twice


    Any input along the way is muchly appreciated! i will try and post up little bits of info and some photos as we go, I really will! haha i usually get carried away in the job and don't remember until the end.....Just like my 1jz hilux project was kinda supposed to do a full log on that :(

    Cheers

    Alrighty we have movement on all three motors in Smc3 Woot Woot

    Can't wait to mount it all in a neat box Permanently, I'm over playing with the arduino pin wires hahaha

    Check out the Video:


    Also @Blame73 @p00ky Do i need to heatsink these or will fans be ok?

    Stay Tuned.....

    Haha Thanks P00ky,

    Yeah i should bloody hope so i'm a qualified fabricator/welder lol, going to start by mounting all the electrics into a box, while i research and draw up my frame

    Heh probably a good place to start, mine are still nailed to a plank of wood :D You have at least inspired me to purchase some proper pots though. I'll look forward to seeing what you come up with & steal any potentially good ideas *cough... I mean....... "Standing on the shoulders of giants" as the great Newton once put it :)

    I always use heatsinks and fans.

    You could probably be fine with just fans, but what you'd want to avoid is to find out that an heatsink would have avoided a damage when it's already too late.
    A few bucks for heatsinks won't surely break your budget

    yeah too easy mate cheers for the input, How did you mount them?

    Just looking at them i wonder if i could thermal paste them and then in the middle section where its all open put a small dob of sika, put a weight on it while it sets, Thoughts?

    I use the ones made for arduinos, raspberries... they already have an adhesive strip, ready to use

    edit: unless I got heatsinks from cpus, in that case I cut them to size and use thermal adhesive stripes

    friend, first congratulations for the initiative, you will get involved and feel how it is like to learn everything.
    I would like you to inform me the brand and model of the pots you are using, I built them with common pots and I didn't like it very much.
    thank you.

    Main Switch/Isolator: 4-Position 200A Battery Isolator Switch with AFD x1
    Main fuse: Fuse Holder with Gold ANL Wafer Fuse 150 AMP x1
    Motor Driver fuses: Unsure? Drivers are 30a (C) and 80a (B) 1sec x3
    Batt-block-3 drivers cable: 6 Gauge Figure 8 Power Cable x2m
    Drivers-block-motors: 8 Gauge Figure 8 Power Cable x4m
    Distribution blocks: Twin M8 Power Distribution Posts x1
    Twin M6 Power Distribution Posts x3
    Emergency stop: Latching Emergency Stop Switch x1
    Relay for E stop: Automotive Relay 150A SPDT x1
    Motor Driver Heatsinks Black Heatsink (H)46mm(W)75mm(L)150mm x1
    Thermal adhesive sheet: Thermal Transfer Tape 100x100x0.5mm Pk 2 x1
    RGB Fans with controller: ID-COOLING XF Series 120mm RGB LED Fan x4

    Battery: Unsure? I’ve never ran a battery with a power supply!
    Cable Glands: Various sizes x6
    Stand offs for boards: 10mm Standoffs x16


    Let me know your thoughts, I need to finalise pricing and i will probably switch some things around a little depending on price as this whole list is made from Jaycar and im sure i can find some parts at a better price

    Cheers

    Update Time..

    So over the weekend i started on the control hub and got my hands on a driveshaft for the uni joint,

    I'm using a rather large box but i wanted everything well spaced out and easy to get to, The threee motor drivers are wired up as is the arduino, i used some servo lead for the wiring between the arduino and the driver plug, and i chopped up a usb extension lead for the pot wiring,I'm hoping i dont get to much feedback from the pot lines as i have little ceramic blocks where the wires are terminated as per pics attached,

    Need to buy two more Rgb fans and cut the holes out, Also need the large relay and cable glands.

    Will this size relay be suitable? Automotive Relay 150A SPDT From Jaycar, On the input to all drivers

    How does everyone prefer to isolate thier rig? before the driver or before the motor?

    Another Question

    Fuses: I relate most of this to cars as thats what i'm used to so: I would put a Large main fuse at the battery, Relay for emergency stop right at the drivers inside the box, then say 40A fuses on each motor? or is that too high or low? or set them at 30A as thats the continous rating of the controller?

    Forgot to take a photo with the lid on :( I will grab one tonight!

    Any Input Apreciated!

    Might have found the perfect power supply today,

    Saw these on Ebay:

    IBM EMERSON SERVER POWER SUPPLY 1975W

    Total output power on 240v Input is 162A@12.2V

    Question is......

    I was planning on having a Battery on the rig as a buffer to the power supply, I'm not going to blow shit up by potentially pumping 160 odd amps into the battery am i?

    Someone with more experience chime in if you have time please, Google is adding to the confusion

    Update.....

    More work on the control box, wiring almost complete, Still need the final two fans, lid is done now, Trying to decide whether to paint :think

    Then onto the frame next week :grin
