Mini Polybius Bartop

(1/6) > >>

BeastlyBoy:
Hello! I'm about to start making a tiny Polybius 'bartop' cab. My idea for this is that it's going to look sort of like the full size Polybius cabinet but much much smaller (roughly 30x30x30cm with an 8" screen). Based off those grainy old photos that are floating around of 'original' Polybius cabs. For reference:



So I want to take some of the form factor and design from the full-size version and shrink it down - square cab shape (I think the 'original' is a Galaga cab), nasty 70s woodgrain, black trim. Almost like it was found in an old warehouse some time, a relic from a lost time. Here's my first Sketchup mockup:





Going to run off a Raspberry Pi. It's going to be a little smaller than a Picade kit. I would go with the Picade HAT which looks like a cool piece of kit but I didn't like that to add illuminated buttons I'd have had to pay so much for their add-on set (£50?!). So I'm going to botch it together myself with a few breakout boards and some kind of USB hub or something.

Definitely took some inspiration from markc74's gorgeous Micro Polybius build. And edekoning's super high-quality Nes bartop.

Going to build it over the next few months but would love any feedback / comments / suggestions before I dive in! What do y'all think of the initial design so far?

Cheers!

I'm leaning towards the 1-button (with a few utility/coin/start buttons stashed on the side) for weirdness factor alone, especially since that's what's traditionally on the Polybius cabs. 6 would be cool but I already have a fully playable cab so playability is not hugely vital with this project.

What do you think?

guess it depends what games you are planning to use on it, that will decide how many buttons you need  :)

what size screen are u going to use 15",17" or 19" ?

Yeah I think I'm happy for it to be just for 1-button games, since I'm building it more as a 'thing' than a totally useful/functional machine.

And the screen is going to be 8"  >:D

Mike A:
Seems pretty pointless to build a functioning arcade cab that is just going to sit on a shelf.

Why not just build the shell? It would save time and money and still serve the same purpose.
