Probably with a bunch of these or something close to it.

Looks like a remix of the under-veneer LED display in EightBySix's Insert Coffee build.




The first thing I would try is make a mockup with the real materials and just light up a few LEDs on a single matrix (no scrolling) just to see how well you can see the individual pixels.

The results are in.

This picture is regular thickness veneer (0.6mm). Not really workable.


And this is with me having sanded it down so it's as thin as I dare make it

Looks amazing, but.....
...then they use garbage buttons (and probably a garbage joystick).

I should just get a t shirt made.

People will break the bank to make their cab light up like a Christmas tree, but they will always go cheap with the controls and the artwork.

  I would have to think this is not done with the intent to use inferior parts but more a result bad parts and counterfits from shady venders, Normally nobody goes out and spends the most money possible to build a machine start to finish because it would be really easy to spend big,  Doing the research and knowing what your buying and buying it from a trusted vendor (at any price) IMO is the only way to ensure quality.... Jennifer would have to say this matrix thing is quite cool, my concerns however are the thin of the veneer would lose its structure and would have to be laminated to a sub structure, However steel IMO would be a poor choice given the expand contract properties as compared to the wood. Delamination would surly ensue.... Unless possibly there was a third layer of aluminum sub structure beneath that as a mounting plate acting as a heat sink.

I would tend to agree with you, but...

Some of the most common questions are "What is the cheapest encoder?" or "How do I get my Aliexpress LED buttons wired up?"

Well that's not stuff from trusted parts venders , But don't forget buying high end components can get really expensive, so rather than spend 3 times the cash on a build try to save a few dollars here and there it does seem apealing.... I would think they would learn there lesson however, and be a bit more conscious on their second machine or the redo.

The problem I see is that if the machine plays like ---steaming pile of meadow muffin--- with bad controls, there will be no second machine.

Expanding on innovation such as the point of this thread is far removed from the new guy thinking he can build a machine on the cheap. Its not a choice but a lifestyle, consciously planning every detail day and night, and dropping everything to test some random theory such as this matrix.... Those guys buying cheap junk have just that when their done if it even ever gets finished or working, and most don't ever come back.

It's a cool idea if you could get LEDBlinky to maybe output the button info through a serial connection.

My wish for the future of arcade buttons would be to have an arcade button house an oled screen. This would not only allow the button to change color to match the game being emulated (which can already be done) but it would also allow symbols to be displayed to mimic console system button labels.

On topic though; how or what software was used?

My wish is that everybody wakes up one day and figures out that light up buttons on arcade machines look like crap. It makes the cab look like a redemption machine.

Everyone is entitled to their opinion. I think lighted buttons look like crap when people use that metal trim around them.

I'm not a fan of illuminated buttons, but do like the idea of button labels (on the CP) that change on the fly to match the game.
It would be great to launch a random sports game in MAME and know what all the buttons do without using trial and error.

I did some tinkering with printed labels underneath dark plexi, each of which could be illuminated by a single LED.
Being limited to already printed words, I never came up with a layout that accomplished what I wanted.
Small OLEDs would be cool.  It would be hard to squeeze SHOOT/BLOCK onto one of those matrix displays.

Yeah, the problem with dot matrix is that you would be limited to a single letter or symbol.  You could try to scroll on it but I don't think that would look or work well. 

However... LEDBlinky has the ability to assign custom names to buttons.  If LEDBlinky could shoot out the button name info over a serial feed, it should be relatively simple to use something like this which would give you pretty good resolution to spell out more words.  About 3000 pixels instead of 64.
