They can't output enough current to drive a motor directly, but several pins could switch a module with two solid state relays like this one.

Thanks Scott - does this also apply to getting a ServoStik to rotate? I'm about to try and get that working with a pi and not really sure where to start...

I'm not sure how much current the Servo-Stik draws, but IIRC most GPIO pins are limited to 15mA.
- A typical LED draws about 20 mA so you'll definitely need an external power souce for the servo.
The tutorial below and ZoOl007 (author of RGB Commander) both look like good starting sources for info on this subject.

Part 8 should have a bunch of info that is very helpful for what you want to do.

RGB Commander can control Servo-Stik switching within linux.

Maybe the GPIO pins on the pi could be used to rotate it? You could have a .cfg file for each game that gets read prior to launch to determine orientation and the motor will react accordingly? I have no idea how to implement this but food for thought.
EDIT: I love the design. How are you going to access the insides? There is no door! This seems better to me because a door needs a handle and hinges and it leaves seams whereas this design will look nice all the way around.

I'm not planning on automating it when it takes half a second to physically rotate it ;D. And things are tight enough in there already! In terms of access, the whole thing will be accessed from the bottom which I'll show below.
--- Quote from: Alejo I on March 19, 2019, 10:28:33 am ---The design works from a visual perspective because it doesn't ignore the most important thing: proportions.
So many modern LCD cabinets look like utter arse because thin profiles make them look ungainly, frail and lacking stability. This one doesn't. Moving the display outwards is a brilliant idea.

Thanks chap. I was kinda using this sort of thing as my original design but then thought if I was going to square off the front then I could easily rotatable (naive idiot I was!)

Made some progress over the last few days. Mostly lots of sanding and a couple of primer coats but then realised that it was pointless getting it shiny perfect while I was still working on it on the bench. I’ll come back to the sanding/painting later once everything has been squeezed in and I know it won’t be thrown around too much.
I’ve temporarily added the front buttons to make sure the lazy susan clears the buttons and it does which was a nice bonus as I completely forgot to measure the depth of the buttons when I was designing it!
Access is via the base as it will give access to the CP and the Pi and leave the top part nice and smooth. Added some rubber feet to keep it stable and they seem to work pretty well. The angle looks off in this pic but it rests square on the table so happy days
I know I’ve went overkill a little on the hinges but they were all I had to hand and figured that with the weight of the cab and people resting on the CP the base needed some support. You’ll rarely see them anyway.
Here’s an inside shot of the cabinet. The only real thing of note is the block of wood that I’ve glued to guide the speaker pieces into place.
Speakers will come next and then the spinny display which I think is going to be pretty tricky. I still haven't worked out how the back control panel is going to work (power/volume etc) but it’s fun to improvise on the go.
