    6DOF
    Edited May the 4 2017: May the Force be with you.
    Edited December the 9th to the 15th 2017: One year update

    I have not yet finished my 6 DOF (far from it), but I thought to add in the first post all the thing I bought so far for it, and how much it cost, while I have the information. I decided to trow in the HTC Vive, the 3D printer and the computer I use to run all this. They are indirect part of the build. It's been a year now. When I started, I knew nothing.

    A computer. Okay, we all have a computer. But is it strong enought to run VR. My laptop was not. Here I was, a Vive in my hand with no computer to run it. I had to build one in a local shop and go with it. It didn't need to be that strong, but hey, it's my thing. I don't smoke, don't do drugs, I don't even drink... I do computer! Video card: Nvidia 1060.

    $1985.35 CAD

    My HTC Vive (helmet, 2 controllers, 2 bases). Because today, a simulator without it, would be a big waste of good fun.
    Total:
    $1,332.78 CAD

    I'll be using 3 arduino's. So far, I had already one and it is sufficient for testing. They are about 30 Canadian Dollars (CAD) each.

    But for now, back to post 1:
    ______________________________________________________________________

    Hello everyone.

    I am starting my own thread about building a 6DOF Simulator like I was recommended to do so.

    I'm am calling it "6 DOF from scratch" because I know about nothing on how to build such a thing. I am open to any kind of design, advices, solutions that may help me get that thing done.

    My motivation is "Elite Dangerous". I love simulated environments. This is why I own a HTC VIVE. I want to feel the movement now. I have a friend who wants to help that is good in mechanics. He wants a car simulator.

    Even though I read as much as I can on the forum, I already made my first mistake by buying stepper motor for testing:
    12V 0.4A 36oz-in Unipolar Stepper Motor
    Now, it look like brushless DC motor are taking over. Oh, well. Better not get discouraged by first of many mistakes. Like I wrote somewhere else, it is not the worst mistake of all, as they are nice little motors that will help me understand the connections with the drivers/plugins/softwares needed to make a simulator move. I will probably recycle them for other little projects later.

    I possess a harduino and a rasberrypi. I have knowledge in electronics and programmation. I am the worst handyman. What could go wrong?

    I want to go for the linear actuator design. I read a lot about the ACTUATOR TWISTING PROBLEM. Can someone develop a bit about this, or pointing some thread that talks about this in detail. I know I am still far away from that part, but I am really intrigued by this. I guess it has to do with rapid direction changes that put too much stress on the actuator structure. I want to understand the causes and the possible solutions to avoid that problem as much as I can.

    Thank you all for your time. Let's see how far this will go.

    It seems to be a tradition to take pictures when we receive parts we ordered. I guess it is a nice way to share the pure excitement we always have when we open those little boxes, like a kid the morning of Christmas.
    IMG_1379.JPG
    My little stepper motors and some ULN2803A to control them. I've never used those. I saw them on a youtube video and they look like a nice choice. Some little proto boards. Its been so long since I have done pure electronics.

    IMG_1381.JPG
    I started cleaning up my workbench. It looked more like a storage place. After some clean up, I started demolition. I had this old music amplifier with burned part. It was time for it to be taken apart. With about 6 type of screw, it reminded me how electronics was design at the time. Most of it will end up in the trash, but it is a nice case, a big heat sink and some serious capacitor. Also, when you get warnings about 8 amp, you know that the power supply can drive most of your electronics project. At the right, it is the board of a internet switcher, that you can see the nice case under the bench. Far left, some wires of a computer power supply. It could come handy one day.

    @SeatTime's build thread is worth every moment of your time, so too is @wannabeaflyer2's DIY actuator thread, if you are interested in building your own: https://www.xsimulator.net/community/faq/calculating-basic-linear-speed-and-forces.89/

    But all of the 6DOF projects are also worth a review, a bit of research is well worth it for such a complex and potentially expensive project.

    I'm up to page 14 of SeatTime build. The think that what surprised me the most, beside he's doing everything out of carbon, is this comment from Speedy.

    Really? A simple computer power supply to drive motors. Even with a car battery or an array of capacitor for back up current, I find this hard to believe. One thing I am sure, I know nothing about DC Motor.

    Let's keep on reading...

    About my stepper motors:

    LOL. Definitively, I am good at choosing the worst option. Since I've done nothing yet with those motors, let's see what Roboshop may offer me for an exchange. If exchange is possible, this bring the question: "What do I exchange them for?". Other motors? I already have little toys motors laying around. Maybe some "Arduino"? I'm starting to be afraid to take decisions.

    Just finished to read SeatTime build. I wan't to copy some info from his thread to make sure I don't forget them.
    Ball screws are around 90% efficient, worm screws around 65% , tried belts -noisy under load. Direct drive ball screws is a win for me.

    I would invest in some Sabertooth 2x32's or 2x60's ;) Good luck with your build lots of learning to be had, I knew nothing really before I came here and I have been on one continuous long learning journey, loved every minute of it.

    Really? I was thinking more some Chinese MM's.

    Kidding of course. Wow! About 250$ CAD, even before the taxes. And that would only be the first one out of three (if I don't burn any). This is what I call an investment into the futur. But I hate to "buy cheap, buy twice". I am sure this would be a nice incitative for roboshop to exchange the motors. We will see what they say.

    I am so close of a finished 6DOF simulator with me on it.
    Okay, maybe not that close. But hey! I am controlling 2 dc motors with my Arduino and a ULN2803A. Powered with the 5v of a computer power supply.

    I used the wiring schema from this page:
    http://newmediaartist.org/index.php/chapter-12/211-maxuinoarduino-motor-drive-with-transistor

    And this tutorial for the Arduino control program:


    Next step, using simTools to control those motors.

    Good news, Roboshop will exchange my stepper motors for a sabbertooth, with no shipping charge. Wait, this is bad new for my wallet... Oh, well.

    Should we really be calling you "Peter Pan" ???

    Good news for the Sabertooth its worth the money ;)

    Pierre, Peet, Peter, whatever you like.
    That multimeter date from 1991. I was working with a girl, repairing Sonatest ultra sound testing device (from England). We all bought those multimeters and she wrote that name to know which one was mine. The name stuck to the multimeter, but never to me.

    I have learn a lot of things this week:

    My electronic is rusty. Fortunately, I have found this little web app (chrome only, 15 ca$) that helps you build circuits that you may simulate after. What I like the most about it is that it shows the curent flow into the circuit. For me, this is a big plus in understanding how things work.

    http://everycircuit.com/

    Waiting to exchange my motor for a Sabertooth motor controller, I try to learn how to control them with the Arduino and small toy dc motors. Motors can be controlled in both direction using simple h-bridge configuration circuitry. But, 3904 and 3906 transistors are bad choice to build them, as the suck out the voltage to be able to provide the current. I should be using Zetex ZTX1049A/ZTX968. I learn all of this in this great site.

    This site also point out to a nice electronic board designer app, free:

    Also, I had this great illumination this week. My brother works at designing micro controlled system for farm and plants. He must know everything about DC motors (D'oh). I talked to him, he showed me stepper motors. I said no. He showed me DC motor controllers (500 ca$, ouch!). I talk about the saberTooth. He talked about 10 turns/10khoms potentiometer. All those great informations. But the thing he was the most emotional about was that every DC motor controller should have a rechargeable battery connected to them, to provide the extra amps needed in big surge. For him, a DC system should never go without them.

    Hi there!

    Another great circuit simulator is LTSpice, which is used often in industry, it's 100% free and incorporates many high-end functionalities.

    Also, a good free PCB design software is Kicad, which is 100% free and open source, and comparable to many $1000+ EDA software suites.

    You might also look into using MOSFET transistors to control your motors, rather than bipolar transistors, as they will get much less hot.

    I tried LTSpice, and it look really good. A bit plain and technical. I prefer everyCircuit because of all the flashy stuff and animation. Research on everyCircuit for other design is a breeze and I already have a MOSFET H-bridge design to look at.

    Kicad looks really good, but I could not find easily a example to compare. It looks more complete and a bit more complicated. I will look at it for sure, even though I don't expect to do a board anytime soon.

    Edit: Just found the time to dive into Kicad and find the examples folder (d'oh). Much more complexe and complicated. Way beyond my actual board manufacturing needs ( which for now are NONE). I keep it for sure, just in case.

    I am still doing research on everything in the field of DC Motors and I am slowly bringing my brother into the field of simulators. He showed me this power supply for driving motors, and I would like to know the opinion of all the experts about it. Good? Bad? Neutral?

    mean well make industrial quality PSU's, better than the cheap Chinese knockoffs.
    i swaped to a small 24v one for driving my AMC1280 after having problems getting stable 24v from the chinese ebay copies, but cant you just buy used PC server PSU's like everyone else? much cheaper

    Of course I can. This is why I posted here. To get feed back, because my first attempt to buy anything for a simulator turns out ridiculously bad. PC server PSU`s, I will be looking for those.

    the Dell 2650 PowerEdge units are nice and beefy for a decent price.
