SNK Positional Gun Interface

[baritonomarchetto]

I am working on my first interface for positional guns. In particular, this will be compatible with SNK guns from Beast Busters.
I have just uploaded a video with my progresses.

The PCB will be the subject of a dedicated article on Instructables and Gerbers and sketches shared.

I have just published a small video showing the PCB in action.
For those interested, here is the link

Nice work on creating this! I was wondering if I can run the recoil arduino as a standalone for just recoil? I already have a button and joystick solution with my APAC Board but I would like a good solution for the recoil in my mounted guns. Are the schematics or wiring diagram available somewhere too? I did see some things in the arduino script but I'm still learning in that department. Thanks

Sure, you can use a cheap Arduino nano to manage outputs. I wrote a full tutorial years ago, with info about driver circuits too. I used the MOSFET driver circuit in this project. Take a look if you are interested (ITA, but you can have it translated)

In the linked Instructable you will find a generous Step about emulators configuration.

Thank you for your help and for all the info you provide. It has helped tremendously with my mounted guns build.

You are welcome

i've done something similary with Lwclone2u ( ledwizz clone ) and a arduino leonardo , outputs for recoil are on the same board with controller input
This project is for an SPACEGUN arcade cabinet
I have a question
When you launch two player and shoot at same time , example in Space Gun , Beast buster etc , recoil doesn't work correctly seem miss sometime
Is it Okay with your configuration?
thanks

I also recently updated the code to work on a single microcontroller board.
I have not noticed recoil losses in two players mode, but to be honest I mostly play alone, like a dog in the desert looking for water and something to eat
Maybe toying with per-gun de/energize times you will have better results (especially considering that, in my experience, two "same" guns could work differently each other)
