[Hardware] 6 buttons stick

[MooZ]

Yo!

I'm trying to build a 6 buttons stick using Emanuele Bettidi schematic. I remade it under Eagle (link).
Here's an image export is you don't have Eagle (link).
I'll try to make the circuit this week. But it promises to be painful as the original board has 2 layers (hires phoso)

Please let me know if I made any mistakes.

you could simplify the circuit by just using a microcontroller to do everything directly. it would be a much simpler design and cheaper.

I don't want to write code that emulates a dump ttl chip that may cost 20 cents

Anyway, I found some errors in the schematics. I also did a board layout. It's not the final version. The 2nd layer is ugly and some paths can be optimized. But it will be enough to run some tests.

Here's the version without auto-fire.

• Schematic (image), (eagle file)
• Board (image), (eagle file)

I'll try to solder a prototype in the next weeks.

Here's a little 3d render of the card I did with this online 3D gerber viewer.

Looks nice. Did you ever put it into an arcade stick?

[MooZ]

Not yet. I received the board last week. I have everything except the enclosure
Maybe I'll take the lazy path and buy one.

I finally started working on the case.

I can't count to 6...

I was at a bbq this week-end. I snatched a japanese hardware hacking book and took some photos with my cell phone
It's basically an article about how to make a 6 buttons arcade stick for the PC Engine.
