Best Electronics or DIY electronics for proton pack? GBfans kits?

hey so I am researching for the electronics i want to use in my proton pack build and there is alot of different out there but i wanted to see what was popular or good electronics kits or diy electronics to use for the pack.

i just want to have the lights and sounds for now nothing else.

has anyone used gbfans electronics? they look pretty good. does anyone know where i could maybe get the schematics on them?

any help would be appreciated. again open to any kits or diy suggestions. i would rather build the electronics myself possibly.

thanks
