Hi all,
First I'm sorry for my poor English (French Inside

), but I search a reply to my question and the only forum which I find is here

Well, I realise my first arcade cabinet and I would like a control panel with a control of led for sticks and buttons.
So I have bought pacled64 from arcadewolrd (better place I think for my country) with 1 pacled64, 2 illuminated joysticks 12V power, 16 ultralux RGB illuminated arcade buttons, and some chrome effect illuminated buttons 12V power.
I would like to power the pacled64 by 12V and connect all leds from buttons and joysticks to it. I had not data sheet, and now, I see a big problem : RGB illuminated arcade buttons have 5V power!
So, I would like to know if it's possible to mix 12 V and 5V powers (I know it's possible to use two pacled boards but it's very expensive with the price of the card and the shipping). I do not have much knowledge in electricity and electronics, so i take an idea from pacdrive web site in the part called 'Advanced Connection Methods' :
http://www.ultimarc.com/pacdrive.htmlSo Is is possible to realise connections like in the attachment or is it crazy

(Grounds from 12V and 5V power supplies are connected)
