I always wanted a Rhythm Tengoku Panel for my Naomi Universal Cab. After seeing skate's Panel, I reached out to Alberto.
He said that he already had a panel that would fit the original Sanwa buttons, just in smaller sizes to fit the available space. After a Rakuten -> Buyee journey I had the buttons in hand and Alberto sent me a panel.
As always the quality of the panel is fantastic and the buttons were a perfect fit. Alberto also sent me the stickers that go into the buttons.

After a lot of crimping I had the buttons wired up. Two connectors for P1/P2 and a third custom one for the lights.

The panel is a perfect fit and works great.

To make the lights work I had to switch the I/O in my NUC from a type 1 to a type 3.

Buttons used are:

2 x OBSAX-C30UM (Start Button)
4 x OBSAX-C45UM (A/B Buttons)
8 x OBSAX-C30UK (Directional Buttons)

bought from the Sanwa Denshi Store on Rakuten via Buyee:

thanks a lot to Alberto for the fantastic work on his panels!

the buttons are quite expensive but I was able to buy them without the LEDs. That brought the price down by about 7 USD per button which is a lot. Then I just installed normal 5V LEDs. The sockets in the buttons can handle up to 30V.
 
Great work! The illumination wiring is totally worth the IO upgrade, it's so nice how the game instructions light up the buttons to show you how to play each minigame.
 
thanks skate, your post really triggered this build. I am waiting for some RGB stripes to put them near the speakers and wire them up on the I/O. Should be fun.
 
I'd love to have something similar for an Egret 2 :) Great job!
 
Hey nnap, sorry to resurrect such an old thread but inspired by your post I also reached out to Alberto for a Rhythm Tengoku panel and I just received it a few days ago. It looks truely stunning (though unfortunately I did put on the A sticker a little too sloppy)! I do have one issue however, The right P1 button and the P1 start always seem to light up. The switch works, but the light doesn't respond to the game and it's just always on for just those two buttons.

I'm also using a type 3 I/O and the harness from Alberto. If I switch the cables to a different button it also lights up, so i'm assuming it's either the I/O or the harness is wired incorrectly. Any of this sound familar to you? Any thoughts how I can start troubleshooting this? Thanks!

looking nice! On the buttons you sort of have 5V, Ground, Button Signal and Light Signal. I could imagine if the Ground and Light Signal were switched, the button would be lit all the time. Check the order of the cables on the connector to those buttons versus the rest. You can also check if those 2 buttons work in the IO test.
 
Thanks! I'll run the I/O test first and see what the results are, and take out the multimeter to check the pinout.
