katuuuz Posted August 19, 2015 Share Posted August 19, 2015 So, sounds pretty impressive, yah? Please anyone with coding knowledge let know if it's possible GameEx-wise.So, along with a useless dell dimension I picked up for $40, came a monitor. It's nothing special, only in that it rotates to stop at horizontal, and it also rotates and stops at verticle... By manually turning it with your hands. (envision monitor model EN7220).Now, upon thinking of how I could incorporate the rotating display into my arcade I figured it would be cool if it could done electrically... which lead me to want it to be done automatically.I couldn't beleive it when I found it, (and so cheap at $12USD) but I'm sure some of you heard of RaspberryPi. Apparently you can get This circuit board and a program called Python to run 2 DC motors, in forward and reverse, at a programmed amount of time.So, if a program on my computer can operate physical motors that turn my motor vertical or horizontal, can't GameEx run that Python program?And if GameEx can run that program to send that command to the monitor motors, couldn't we just get completely crazy and have it send the horizontal or vertical signal to the monitor PER GAME? Imagine selecting Frogger from the games list only to watch it boot up vertically as the screen rotates into vertical position!! Then boot back out to a vertical GameEX and then select Mortal Kombat and watch the screen go back to horizontal?!Maybe I'm a little over ambitios, but if a basic motor, gear and some sort of chain or pully can make this happen, I want to do it. The only thing I'd need help with is the software end, launching the Python program and commands end... Quote Link to comment Share on other sites More sharing options...
tthurman Posted August 19, 2015 Share Posted August 19, 2015 Where there's a will there's a way!One of the coolest features I've ever seen incorporated into a cab.Anytime it's something really cool, RockyRocket's probably done it Quote Link to comment Share on other sites More sharing options...
tthurman Posted August 19, 2015 Share Posted August 19, 2015 I looked at this some time ago too, your post has sort of rekindled that rotating desire A link to a mechanism is in these comments.There are lots of creative methods. Quote Link to comment Share on other sites More sharing options...

stigzler Posted August 19, 2015 Share Posted August 19, 2015 Will watch with interest. Seen a few different approaches, including bycycle wheels, expensive actuators and cheaper stepper motors. Guessing the cheapest would be two motors with stopper switches when a monitor reaches 0 or 90 degrees.so wish I had designed a rotating into mine.Look forward to seeing your build.

Trying to work the kinks out of my mame compile, getting GameEx ready, (still waiting on MAMEDVDS to get me my 1063 set) then the manual labor begins On a very early and weak first note: I ordered a 4.5v dc motor today. 1500rpm, probably going to be too small to do the job. But I wanna have a look. Quote Link to comment Share on other sites More sharing options...
katuuuz Posted August 20, 2015 Author Share Posted August 20, 2015 Hmm. Got in touch with Jrok who has built a non-motorized rotating display... The giant bearing he used that I asked him to point me to costs $115! Have to wait until the girl gets back from vacation and see what she thinks, she's already displeased with the proposed arcade budget not including this bearing.

Draco1962 Posted August 20, 2015 Share Posted August 20, 2015 Are you using a CRT or LCD/LED monitor? Quote Link to comment Share on other sites More sharing options...
Adultery Posted August 20, 2015 Share Posted August 20, 2015 I'm more impressed personally that she approved the budget prior to that! :-) Quote Link to comment Share on other sites More sharing options...

katuuuz Posted August 20, 2015 Author Share Posted August 20, 2015 Hahaha I know. If it were up to me our 3rd bedroom would be an arcade. She is a doll and deserves a lot of credit for putting up with my inner nerd. Plus she'll be all over it when it's done 😉Draco: I would love to use a crt, I have a 22" tube tv I had plan to use, but if I can muster a way to get rotating, I might have to opt for a lighter weight LCD.

Draco1962 Posted August 20, 2015 Share Posted August 20, 2015 An LCD monitor would definitely be light to mount and probably would not require such a heavy bearing. Have you checked out the BYOAC forums for similar build projects? Quote Link to comment Share on other sites More sharing options...
katuuuz Posted August 20, 2015 Author Share Posted August 20, 2015 I've seen those videos in this thread and jroks. Haven't seen any type of motorized instructional or anything like that.. Quote Link to comment Share on other sites More sharing options...
Draco1962 Posted August 20, 2015 Share Posted August 20, 2015 Here are a few links from TopJimmyCooks:BYOAC: http://forum.arcadecontrols.com/index.php?topic=112424.0and the correct companion link: http://forum.arcadecontrols.com/index.php?topic=112424.0One thing to consider an LCD over a CRT or TV is that there may be some video distortion due to changes in the magnetic fields as most CRTs are designed for a single orientation.

nullPointer Posted August 20, 2015 Share Posted August 20, 2015 One thing to consider an LCD over a CRT or TV is that there may be some video distortion due to changes in the magnetic fields as most CRTs are designed for a single orientation.Spot on. I'm sure most of us old timers remember having to do this with our monitors from time to time. Quote Link to comment Share on other sites More sharing options...

Holy shit man that kid is like the ancient alien of arcades! Thanks what a great read Drac. Just googled the parts, and the motor, driver, controller, are about $160. I mean doable, but damn, way off budget. That dude is crazy, that's way out of my league. I did get a better understanding of how it all goes, moving parts etc so thanks man, I can try and take that knowledge and try and whip up some sort of, *ehm* ghetto apparatus.

Draco1962 Posted August 20, 2015 Share Posted August 20, 2015 For a low tech solution, you could mount a VESA mount to a lazy susan type setup and manually rotate the monitor. When are just pricing the bearing at $115, $160 ain't that bad. Quote Link to comment Share on other sites More sharing options...
katuuuz Posted August 20, 2015 Author Share Posted August 20, 2015 I totally understand when comparing the two... when the girl gets home can I give her your email?? Honestly, haven't purchased ANYTHING yet, save for $40 worth of abandoned materials. DVI to VGA cord and a shitty graphics card for a PC i've since abandoned for this luckily free win7-64 hp machine my sister threw out bc it was "broken". So I'm already starting neggy.If I can try and make it happen all together for like $50 bones, I could probably swing it. Quote Link to comment Share on other sites More sharing options...
Draco1962 Posted August 21, 2015 Share Posted August 21, 2015 Hey, I have my own lady I have to convince to let me spend on the hobby, so your on your own, pal! Honestly, I have seen some great ideas come from frugality and ingenuity. Quote Link to comment Share on other sites More sharing options...
katuuuz Posted August 21, 2015 Author Share Posted August 21, 2015 I hear ya. Got a pretty tech-savvy friend to whom I've pitched the idea. I'm sure we'll rig something up. And hey, if not maybe I convince her down the rd to build a Nintendo style cabaret if the rotation plan runs out of funds and I go fixed horizontal 😁 1 Quote Link to comment Share on other sites More sharing options...
Draco1962 Posted August 21, 2015 Share Posted August 21, 2015 If you do some searches... OK, lots of searches, you will find where people have rigged electric screw drivers, drills, even DC headlight motors as solutions. I will be curious to see what you come up with!
