World's Smallest Arcade Machine (Guinness Record)

[Art]

I haven't written Space Invaders, but I ported it to Canon Digital Cameras:



I would see what I can come up with on a test board,
but there might be trouble if licensing for that game and it's cabinet graphics wasn't granted first.

What about pong, brickout and tetris?

It doesn't have to have any or all of the games of the current one.
I'd like to do one game, but make it a better one, hence the original driving game idea.
Tetris, I already wrote for my 144 LED matrix, so it's a bit too easy.

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).

Your pm is full

Hi :)

In a nutshell, I'm wondering if you're interested in participating,
as in building a cabinet as small as you can, keeping it's dimensions to yourself,
and sending me the schematic so I can write a game on a bigger breadboard version.

I can probably arrange the joystick and buttons for free, and am also going to try to get some displays.
I think Sparkfun will play ball for this kind of project.

In that case, I would reapply to Guinness as a PBP group.
It is good to leave my application open in any case, as I can check the record daily.
It's fine if you're not into that, but I would certainly opt to avoid building the hardware if possible.

Cheers, Brek.

Hi Art,

Sorry for the PM inbox being full.

About the cabinet, i will be happy to participate.
The design i have right now is the smallest i can go because of the nokia lcd ( breakboard ) and for my tactile buttons but it's possible to do it smaller.
The MCU i'm using is a 18F2520 which has alot of programming memory ( great for storing lots of screen pictures ).
The same PCB can be used in a way that instead of sensors you can use joystick or other goodies.

Here are some more recent pictures of the cabinet with buttons and pcb:

It's possible to use a small joystick instead of the buttons.

Does your game have to be "perfect" in the sense of variable angles depending on where you hit the ball on the paddle? I'd keep things simple with a fixed angle, say 45deg for example, and then it's just a simple math (addition/subtraction) of coordinates within a set range.

Does Guiness impose your gameplay to be "exactly" like the one in arcade?


About the controller, are you allowed to use a stylus to operate it? Then you could use a tiny potentiometer with a dimple on the surface of the cap to act as grip for the stylus tip.


Does the unit have to respect the proportions of an actual arcade machine? (case, display, controller) If you do, where would you get those?

Have you considered a 64x64 graphic LCD?



There has to be competition out there to use 128x128 again. I'd look seriously at staying one step ahead of the next guy; no more than 2/3 the size of the current record holder.

I would think a smaller LCD would also mean simpler gameplay.

It mustn't have to be spot on, as the current record isn't in terms of cabinet or games.
I don't think there was ever an arcade machine with those three or four games.

If it does turn out that I don't have to be responsible for a cabinet,
then I think I should, and can do better than any of my previous games /gfx.
Even if the screen res doesn't allow for proper sprites,
playability, and true to life nature would still nail it.

ruijc, without giving dimensions in public, do you think your current cabinet is small enough?
It does certainly look like it can be made look real very easily.
The record is an easy target. There are a lot of people in this world capable of this.

I will reapply today in the name of a group, no matter, since it takes so much time for them to look at.
Give me a day or two.. I'll also see if Sparkfun will do anything to help.

Hi Art and PBP group

I've been silently following this thread for the interesting stuff going on here. Have you considered the 0.96" 128x64 monochrome OLEDs out there? It is about the smallest you can get today. I have used such in the recent past and they are really small. much smaller than the Nokia 4k color display or the Nokia monochrome. Programmable via SPI just like the Nokia.
