    Hello Everyone,

    First off big Thanks to the many people around the community for providing tons of informative information required to help me try to achieve may goal.

    The Idea

    The idea of building a motion simulator came from seeing many diy projects across youtube and some sim racing forums. After seeing so a large number of motion units I fell in love with the unit of Tommy06, with that design it look's simple and it does not takes much to make me happy :). Seeing this has gotten the creative juices flowing as I'm capable in fabrication, really happy that Google is round so I decided to do search for DIY Motion Simulators and here I'm today (Icing on the cake) that search provided a page with the works of RacingMat walk around which has proven to very beneficial in given me the Inspiration to push myself. Thanks RM for you continuous help.


    Direction

    I have chosen to use the Arduino UNO board, Moto Monster and the HP DSP-600pb power supply. As I currently don't have a consistent job right now I'm going to use 2 wiper motors 12v, and when more monies come my way I will purchase a set of worm gear beasts recommend by (Eaorobbie). I have to get 2 potentiometers, some wires and maybe some other little things nuts and bolts etc.

    Software

    Arduino IDE ver 1.0.5 and Sim Tool

    With the downloads completed I have gotten both software install now an looks to be working

    Well today is the last day of the year here on this side for the world an I just got the power supply today after ordering it about 3 weeks ago :), so out goes 2013 and in comes 2014 hoping to have a Awesome start to the new year.


    A very blessed and prosperous new year to the X Simulator Community

    Wipers will get you moving if your sim is all balanced nicely, should last long enough if you dont wind the motion up to the extremes its capable of, or the internal gearing will eventually wear, and again I can not stress this enough,
    wipers have a gnd connected to the body of the wiper if you do not mod or remove this the frame will become live with 12v's and because pots gnd the earth to the body as std the 12v will travel through the pot to the motor driver gnds and because on most usb devices , the Usb ground is interconnected too and you end up frying the usb controller on the pc's motherboard, or worse the controller of an expensive steering wheel.
    Please be ultra careful using wipers, This is why I don't recommend them, seen too many destroy too much. Plus most wipers don't have the same speeds as each other.

    Not all Wipermotors are grounded to the body, you have to measure it before. My old Wipermotors wasn`t grounded to the body. Now i`m updating my Simulator with 2 big worm gear motors (12V , 15A, 180W, 177rpM)
    If you have different Speed, you can influnce that whith the Kp-Settings for each motor. That was possible with the AMC-board, don`t now if this possible with the SimAxe Motion Controller too?.

    Does the car manufacture has a lot to do with this ground design problem?

    My country mostly use Japaneses vehicles hope that is not a problem, but I was thinking of getting myself motors from the "Ford Explorer"

    But if I do come across the gnd connected body type, is there any documentation on how to remove/reposition it?

    @Michael N. Thanks for providing some info on the isolating of the motors, after reading the post I saw a photo of a AE101 wiper motor which I my case that is either/or a Toyota Levin or a GT Corolla 93-95 models, and quite attainable here in my little Island :thumbs :cheers:);):);):D:thumbs

    test the wipers regardless, spending 30 mins testing to see if they are grounded to the case is better than blowing the control boards and or the pc.
    As for earth isolating, depends on the wiper, sometimes a rewire or finding the wire going to the earth of the case can be changed, sometimes it means pulling apart the motor and hacking the inside.
    I know wipers are cheap, Ive been through heaps, but since going to big worm gear motors, which are already earth isolated, they have saved me more time than the extra money spent.

    Finally bought me (1) length of 1" tube for the rear section of the motion chassis, going to do some cutting and welding today :)

    Hello
    In the picture I see that you have three circuit boards, can you tell me name of boards.
    Thank you

    @Ramok His using a Arduino R3 and Monster Moto Driver to control 2 wipers. All in his first post.

    Due to not owning a rig before I decided to build a complete unit :)

    Cutting by hand is not fun at all :( but it makes the finish job worth cherishing more:cheers

    Wow I love that back support style ... Great progress indeed :thumbs...
    If I may suggest, give it a little backward bend to make more room for the chair if not well seated ...
    And you have more followers now :popcorn... you may have some and get back to work .:grin

    I agree, having and angle behind the seat lets you make the sleds overall size smaller. I did the same thing. I made mine at a right angle, found that it does not work well like that and then cut it apart and made it at an angle to fit the chair.

    Overall well done!

    @Kevin thee Bajan one quick thing , I might be seeing wrong thou, the pivot point is close to the base of the chair because if it is not the weight and resulting motion will be an issue later. The further away the centre of the pivot is from the cg of the rig will cause your motors to work very hard. Pivot needs to be as close as possible to the base of the chair.
    How did you work the balance point out, I would suggest building the top part completely and placing everything on the top part, as in wheel, pedals, keyboard, etc and placing a round object under the the rig with you sitting in it to find the exact place the rig will balance at, this point is where the centre of you uni needs to be and as close to the bottom of the seat. All done to get the best out of your motors and H Bridge. The more balanced it is the better the resulting motion will be.

    Hello Kevin, I am also using an Arduino Uno and a Monster Moto Shield. Do you have a wiring diagram for these ? also how did you set the SimTools game Engine up? in the Interface settings ?

    Regards Nath
