ROMNI - My 3D Printed New tiny RecalboxArcade :)



  • ![alt text](0_1493615945927_Romni_03.jpg image url)

    I would like to present my new project. My 3D Printed tiny recalbox Arcade. with sanwa control, 3.5 screen (composite), sound, batteries, etc. Hope you guys like it ! :)
    (The shaft will be replaced by a shorter one soon). :)
    I can´t wait for Recalbox 4.1 so the project will be "more" complete. :) And i have a question...Is it possible to have composite video working and auto-change to HDMI output when using the hdmi output ? My Romni arcade has a hdmi extension on the back, but when i plug it, the hdmi only show the first colored box on Pi boot then it goes to the composite... I followed the tutorials to have composite output, and maybe they FORCE the composite output... But i would like to be able to use the internal screen and the external monitor (hdmi). NOT at the same time of course...

    Is that possible ?! 
    
     This is my first post on this forum. Glad to be here. :) Thanks !

    Hello

    good projet :D , screen too small for me,
    recalbox 4.1 https://archive.recalbox.com/updates/v1.0/unstable/

    @Marcelo-Souza I love it, really beautifull !

    But maybe a short handle for the joystick would be better ? It seems to stick out a little too much compare to the size of the bartop

    I love it. Great job

    Yes. Certainly ! :)
    I ´ve mentioned that the shaft will be replaced by a shorter one. This one was used just because it´s the only one i had at the time i´ve built it. :) It´s 7cm long, but i don´t have all this space inside the case, so, i rebuild all the internal parts of the original sanwa with 3D Print, to reduce the size, and leverage the shaft by 1cm (this red ring on it´s base)... Using a shorter shaft, like 6cm i will be able to remove that red ring, so the shaft will be lower. :)
    But anyway, it´s working perfectly and not getting in the way of the screen. So it works for now. :)

    Hello

    Thx Acris !
    I am waiting for the stable one. But but maybe i will test the unstable for curiosity sake. lol.

    I agree that  the screen is not for everyone. But it´s a design/cost option. It´s very hard to find bigger screens, not SO big to have to change the entire design/power scheme, that has composite input and it´s cheap. That screen i am using is around $25... And i live in Brazil, so it´s not easy to get anything i want to + the import taxes can be like 100% the price + shipping... So, the decition has a lot of constraints. But it´s a nice screen for it´s price, and it´s bigger than my dingoo a320 screen. If i am able to find a good Cost Vs enefit on a 5 inch screen that would be perfect. And as it´s a 3D printed case designed by me it´s just a matter of modifying the 3D model and printing the top part again. 
    
    
     BTW...Any clue about my Composite/HDMI question ? Is it possible to auto-switch to hdmi output when a HDMI cable is present ? (Even if i need to reboot it) ? 
     BTW 2 : I don´t know why my posts here are being showed on a black box... :(


  • More Pics ! :) BTW this project is not 100% finished on it´s design. It´s the Prototype #6 (6 case printed until now). So there´s some minor updates/differences between some pics. :)
    This is the prototype #6 :

    Some shots of the new Back with removable plate, so, i can use any different board, and have a more futureproof design. I just need to reprint the red plate to fit a new configuration for the board ports. :)

    A shot of the front control pannel. With Power ON/Off button, Hotkey, Select and Start buttons. :)

    Hello @Marcelo-Souza

    I have the same problem to buy products.

    for your question hdmi :

    try these :

    mount -o remount,rw /boot
    edit this filenano /boot/config.txt
    add this line : hdmi_force_hotplug=1

    when you start without hdmi cable, normally it's ok
    et when you plug hdmi cable, normally it's boot to TV screen



  • Thanks for the Tip. I will try it now ! :)

  • Hi ! Nice game&watch arcade cab ^^

    For your question regarding composite/hdmi auto select ... Hard to tell, i'm not sure anyobe ever succeeded here



  • I am back to this posts. Just to post a possible "solution" for my obvious question... A way to Auto-Switch between HDMI<>AV... It seems that this guy made a script that Detects the hdmi plug and switch the config settings...

    Hope it works ...

    @acris Hey.

    I´ve changed the lines with hdmi_Force_hotplug=1 and then it worked, the recabox and games apearead over hdmi (video and audio) but now , even after unplugin the hdmi and turning off and on the system again, it´s sticked with hdmi output... The monitor i am using only turns on if some signal enters over the composite in... so it seems that pi isn´t sending composite signal anymore after i unplugged the hdmi cable. I will reverse the config edition to check...

    I love it all very much



  • Finally reach the beta stage with my project. :) Hope you guys like it.
    Now i need to build a custom theme, since the latest recalbox has "SMALL SCREEN" themes, but the gamelist font stills VERY tiny... Unreadable. :(

    You can edit the themes and increase the font size very easy.
    By the way, I also find it very nice, and having some 4.1" compo spare screens, I think about it.



  • It looks just amazing.



  • Much better than the neogeo mini !
    And you can have all the neogeo games collection in it ;)


  • Themer

    @marcelo-souza beautiful !

    how are the buttons ? I've always wondered of those kind of mini buttons were and felt as good as the standard ones


  • Team

    @voljega if it is small "service buttons"... they are very hard; and it is difficult to play with.
