Question First timer 2/3DOF build questions

Hello all! This is my first post here and I just had a few questions before I got started ordering and searching for parts. I've looked at a few tutorials (I'd mostly be following the 2DOF Motion Simulator Wiper motor tutorial, but depending on how much I can get motors for I might go for a 3DOF) and was wondering what kinds of truck wiper motors would be effective for a sim? If someone has any experience with say F-150 wiper motors or any other kind of truck wipers that I could find at a PickAPart I'd love to hear about it! Along with these wipers I would be buying an HP DPS-600PB B and following the tutorial on how to mod the PSU to use with the motors. In addition to these parts I'd be buying 2 or 3 10k pots, a MotoShield, and an Arduino UNO once they get back in stock or I'm recommended a suitable replacement that doesn't cost an arm and a leg! If anyone has any recommendations or advice I'm all ears. One more thing. Is the difference between 2 and 3DOF notable enough to warrant spending that money on another motor? I haven't been able to find very many comparisons online of the two and I wondered what you guys think? Thanks for reading, and thanks in advance for your help!

Thank you for the reply! I haven't been able to find a spec sheet for the motors, but my buddy has the same model truck so I'm going to measure the speed when I find time. I'll be sure to check that calculator out for when I start designing thanks for the link! As for the 3DOF is there a notable difference between 2DOF and traditional 3DOF?

Sorry for the late reply, its been a busy couple of weeks. I've thought about what you've said about the 3DOF systems and I've looked at a few members setups (including your awesome compact design) and decided that since this is my first time working with these things to just take it slow and do a 2DOF non-compact build. Instead of using metal for the seat/controller mounts I started looking into using 2" PVC pipe. Its both cheaper and easier to work with than metal, at least for me personally. I'm planning on doing shoulder mounts so that I can get away with weaker (cheaper) wiper motors. I've also been throwing around the idea of switching from the UNO to a JRK for the motor boards and using Hall sensors instead of pots. What do you think about that? Is there anything you would recommend or advice you'd give?

Would I need one or two PSU's to run the JRK's and motors? I've noticed people using just two wiper motors use just one PSU, but would there be any advantage to having one PSU per motor?

Okay so I should be fine using less powerful wiper motors then. I'll order one for now and see where that gets me. Thanks again for all your help!

Okay so I've finished my summer classes, moved into my apartment, and have a week before classes. Time to finish this thing! I've decided (a month or so ago) to change away from the pipe dream of a full frame mover to just a seat mover with wiper motors. My dad and I grabbed a U joint from a friends junk pile, cut it and welded it to a bracket I designed (finally got to use those Solidworks skills Ive been working on ) on the bottom of the seat. That bracket also has a metal T with a bar near the top that runs up the back of the seat for a shoulder mount. The bottom of the U joint is welded to the bottom bracket bolted to the PVC. Motors are mounted on metal plates and bolted vertically and horizontally to the pipe. Shes not pretty but she works Motors are attached to a piece of metal we dug out of the steel pile out back with a bolt welded to the end for the hiem joints. I've wired the PSU for 12v and tested it with the JRK's and motors without pots attached and they work! I just attached the pots with hot glue and a cardboard holder. They stay put when they need to and when the motors accidentally spin uncontrollably because you forget to apply settings to device it just tears off and saves a pot! I haven't tried working with Simtools yet because I still need a licence, but I've been reading tutorials and getting a lot of information on the subject so I'll be prepared when I get there. But I've got a question about how sims behave in aviation simulators; What happens when you go inverted in the program? Obviously the sim can't turn that far, but would it just go as far as it could one direction and then really fast move to max on the other side and come down or how would it handle that? I've been playing around in DCS and wondering how it would work out in a chair?

Okay awesome, Ill start the download on that now and work on it this weekend. So when you roll the sim will max the direction you begin the roll, then return to the normal when the roll ends? That makes a ton of sense and I can see how that would work well with VR. For now I just have my phone, a Google Cardboard, and a $15 application that fakes Vive sensors for VR, but it works surprisingly well with DIRT Rally and DCS. My school allows us to check out a Vive or Rift from the engineering library so I'll have to try those when its all said and done. Thanks for shedding some light on that roll issue though!
