Arcade joystick help

Ecks

Also thinking about the bottom part to maybe cut it a little more.

@tmntturtlguy I wanted to ask you personally as well do you think this system could handle RetroPie with no problem because i know the HD 8550G can handle certain PC games good but more or less for games like Killer Instinct you know because if this stick works out well i plan on building a full size 2 player arcade system and thought of using a mini PC like this one and it will only be a RetroPie mame machine as well.

@ecks in regards to the control panel, typically you need to use a router and take 1/2" out of the bottom of the wood. This should be sightly larger than the joystick, the joystick unit then sits in this area so that the stick is the correct height and so the bolts can hold it in place nicely.

I understand you 8 button setup, what are your 2 buttons way to the right? Are you doing a coin button and an exit button over there?

In regards to the mini pc, I guess if it is a windows pc it should run the pc version of retropie, I am not very well versed on this, I only run retropie on raspberry pi 3's. I do know that retropie does not run on all of these other little computer boards like the asus Tinkerboard. You might want to start a new thread and post some more info on that mini pc and see if anyone who runs the pc version can help you.

@tmntturtlguy Thanks and the 2 buttons on the right hand side is start and select or start and coin also as for RetroPie on PC you can install it with the Ubuntu OS as you can see here and also to regards to the bottom area i have the joystick area like drawn out so i know where to shave it down right now.

@tmntturtlguy I have an off topic question about power plug for the Pi because recently with Dreamcast for some games i get the low power warning and the one i am using now is a 5v 2.5a power supply and was wondering if i got something like this or like this if it would help with the low power warning and also i got a newer case recently that uses a fan as well which is why i am looking at that 3A - 3.5A plugs.

TMNTturtlguy

@ecks I can't help you with that. I use a 5v 2.5 amp with a .15 fan and never have issues. That is all I know in this area.

Ecks

@tmntturtlguy Ok thanks just wanted an opinion if i should just get one with 3A on it because i might do other things like adding a LED indicator and a power switch from the GPIO.

@ecks
Are you using an official power supply or a third party power supply?
2.5 amps should be plenty and I've always found the official power supplies to be reliable but have heard some third party power supplies can't supply the current that they advertise.

Ecks

@ruckage I am using a third party and i have tested it out it is generating what it should because i also have a 2a one from my tablet which always gave me power warning when playing SNES games and also Dreamcast would use more juice anyways as well and like i did mention i plan on adding more things to me Pi like the power button and LED indicator light.

@ecks
A rpi3 draws significantly less than 2.5amps even under full load so the most likely cause is that your power supply simply isn't good enough. 2.5 amps is only recommended so that enough power is available if you have power hungry devices connected to the pi. For example I had the pi and a 7inch touchscreen both being powered by a single official 2.5amp power supply without issues.

A power button and LED isn't going to have any impact, as @TMNTturtlguy said I also have a Fan and LED powered through the GPIO using the official PSU and have never had a power warning.

You either have something very power hungry already plugged into the pi (hard drive maybe?).
Your raspberry pi is faulty.
Or you need a better PSU (I think this is most likely, just buy the official one - it's not expensive and works well.)

@tmntturtlguy I am going to redo the top part of my stick just because i dont have the router to make the joystick area thinner so i bought thinner wood and also the back panel where the wire comes out from will be thinner as well.

TMNTturtlguy

@ecks Sure - makes sense. You can also just buy a joystick extension as well. Joystick extender

Not sure where you are buying from, but they have them on ebay, amazon, and most arcade parts suppliers.

Ecks

@tmntturtlguy Ok i redid my board which the buttons i find is a little far apart now but alright with my big hands anyways and also used Plywood.

also i messed up where to screw my joystick and just going to use wood putty over it and do the holes again.

simonster

I did my 6-button layout using the StarCade layout from http://www.instructables.com/id/2-Player-Bartop-Arcade-Machine-Powered-by-Pi/ . This helped me to get a consistent layout with good button spacing.

Ecks

@simonster Well i wanted to have the normal way for street fighter 6 button but also for neo geo 4 button layout as well.

TMNTturtlguy

@ecks looks like good progress, putty and sand paper should do the trick.

Ecks

@tmntturtlguy I got to ask when using wood putty do i have to wear protective gloves?

TMNTturtlguy

@ecks I have no idea what plywood putty is, but if you just use a common wood putty or wood filler there is no need to wear gloves, you just use your finger and or putty knife to apply it. Read the instructions on your wood putty.
