World's Smallest Arcade Machine (Guinness Record)

[Demon]

Crystalfontz also has 42x65, only downside is ST7565P controller with SPI interface. Too bad 'cause these are less than half the size.

and joysticks to correct scale of the arcade machine.

That leaves out joystick and pots, pretty much only buttons using a stylus.

Galaga; with left-right-fire.

Oooooh, asteroids!

I don't think that the buttons and joystick will be a problem.

The ones I use in my cabinet are normal "through hole" ones and the caps are a bit big because I wasn't looking for scale detail for this.
instead I was looking for some great looking buttons with the ability of backlight.

Anyway...

There are many miniature tactile buttons and joysticks on the market today. And these joysticks have 5 positions ( left/right/up/down and click center ) The center contact can be ignored and a couple of miniature tactile buttons can be added next to this for fire or any other function that the game will need.
Just look at the ones used for cellphones. The button/joystick cap can be custom made easy.

Art,
I have the cabinet designed in cad with the measurements already scaled to the size of my project.
I can send you the files for you to take a look and check.

Will send you a PM regarding this.

Regarding the cabinet, why not ask for a sponsor from a 3D printer manufacturer? Instead of a wooden one, this plastic will be much thinner and smaller at the end. Is ther any rule that cabinet must be wooden, Art?

Breakout, I like the idea of a pot for the control, there was a breakout arcade machine with a knob,
but I need trigonometry that I have not yet solved in PBP (ball bouncing off walls at inverted angles).

Regarding trigonometry, I think it can be made easier, with just two cordinates that move the ball. The perimeter is known, the ball has two cordinates it moves (x,y) and then if it hits the wall, the appropriate coordinate is reversed (-x,y or x,-y or -x,-y).

There is.

...The game has to be based on a real arcade machine,
and the arcade machine made from the same material as the arcade machine (I'm glad that's mostly ply then)...

Somehow they permit LCDs to substitute CRTs.

Ooops, I missed that. Thanks Robert.

Yes, that's right. I was going to suggest that to Art, but you beat me to it first. Anyways, very interesting thread and a nice project.

Also, nobody has mentioned how to power the cabinet. In a picture posted by Art of somebody's else work a cabinet is powered by a 9v battery. Instead, I think some coin cell batteries would do the job. They are smaller in size, and it doesn't have to last for hours. It's just for the show and the display for the record.

The rule was the cabinet must be made from the same materials of the original machine the game is based on.
It's possible that Marcus only showed them one game, and the fact that it also runs others might be superfluous,
but I've not yet figured out how it is based on any particular cabinet.
There is no mention about the screen or joystick material, just the cabinet.
It is likely that some of the parameters are based on the first record.

If anyone wants to create a new record, you can simply apply with that.
Say you think you can jump the highest, and there was no record....
then you can apply for a new record category, but if you're white like me, your record will be beaten,
and that's what I think will happen here, no matter who does it.

I have some screens on the way in matching pairs, but not till the new year,
and I've also made enquiry to Madway and Tatio with regard to Space Invaders.
It was originally to be called "Space Monsters", and that name is not licensed.
Since looking at my Canon port in detail, I really like the idea. It is a landmark arcade machine.

If you look at the Canon port on YouTube, there are ways I made allowance for the low res screen.
rather than compromise on sprites, it's just as possible to reduce the number of invaders (oops, I mean Monsters)
on the screen. For the Canon port, I also ditched the barricades.

It would be possible to alter the cabinet graphics enough to be familiar I think,
without running into licensing issues... not that I think there would be any legal action anyway.

Space Invaders does an awesome trick I found on Wikipedia.
As you shoot Invaders, less sprites have to be drawn to the screen, and the game naturally speeds up!

To top things off... look at the cabinet design, and joystick arrangement:

Hey Art, any progress to report? I don't mean to be pushy or nosey, just well... very interested.

So often I have difficulties with the physical construction of a project. The idea is sound and the programming works, but some part fails to meet the parameters I require (for the money a hobbyist will spend) or some unintended consequence is included with part that did not show in the picture or, oh pooh, I just calculate incorrectly. I'd love to see/ read/ hear how it goes for others.

I'm hoping you are enjoying every success!

how your project going art ???
